SPONSOR
This activity was sponsored by the National Bureau ofStandards in cooperation with the American Standards Association(ASA) which represents both the industrial and Governmentalinterests of the United States in international standardsorganizations. The Pan-American Standards program of ASA isdirected by Committee L23 of ASA, To accomplish this work^Committee L23 receives technical guidance from other nationalorganizations concerned with the development of textilestandards: Committee D-13 on Textile Materials of the AmericanSociety for Testing and Materials (ASTM)i the Executive Com.-mlttee on Research of the American Association of TextileChemists and Colorists (AATCC)i the National Bureau of Standards(NBS)^ assigned the responsibility for the Federal StandardTest Methods for Textiles of the General Services Administration(GSA).
3 • TliE INTERNATIONAL SEMINAR ON TEXTILE PRODUCTS
3 , 1 INTRODUCTION
By way of introduction , the first International Seminaron Textile Products^ held in 1963^ was eminently successfulin that of 18 PASC Draft Recommendations approved by theSeminar j, I 5 have since been accepted as Pan American Standardsby the member countries of PASC (CPANT).
2
The second International Seminar on Textile Products,under the auspices of the Organization of American States (OAS),was a working meeting of Technical Coimittee 6 on Textiles ofthe Pan-American Standards Commission^ (PASC/C6). It washeld in Lima, Peru, from October 26 through November 14 at theInstitute Nacional de Normas Tdcnlcas Industrlales y Certlficacion(INANTIC). INANTIC, the official standards organization ofPeru, holds the Secretariat for Pan-American Standards forTextiles
.
The objective of the Seminar was to develop textilestandards for Latin America, a continuation of the programinitiated in I96I and advanced in I962 and I963. Two reportsby Dr. Herbert F, Schlefer, NBS Consultant on Textiles, andone by this writer discuss the programs and accomplishments ofthese years. They are NBS No. 7585 (August 6, 1962)1 NBSNo. 7770 (December 19, I962); and NBS No. 8I96 (February 26,1964).
The Seminar form of meeting, so successful in 1963, wasthat of the 1964 working meetings of PASC/C6. Again it broughttogether, at one time and in one place, delegates of themember countries of PASC and provided the time required forthe discussion, development, and approval of a number of standardsconstituting a most ambitious program. In addition to thesevery obvious advantages, the Seminar afforded an excellentopportunity for the delegates to become acquainted (or to renewthe friendships of I963), and to discuss and cooperate onmatters of mutual interest to our American countries.
Because of representation by the member countries of PASC,and attendance by all of the active members of the TechnicalCommittee, the Recommendations developed and approved by theSeminar were equivalent to one of the stages of the PASCprocedures (Article 5 of the By-Laws) for their acceptance.Consequently, the Seminar provided a means for acceleratingthe adoption of international standards for Latin America.
Thirteen countries were represented by delegates at theSeminar: Argentina, Brazil, Colombia, Costa Rica'^, El Salvador^,Guatemala^, Honduras^, Mexico, Nicaragua^, Peru, Uruguay, theUnited States, and Venezuela, Chile, a member country of PASC,was not represented, but participated by letter.
“I
“^Formerly, the Pan American Standards Committee.^The Institute Centroamericano de Investlgacion y TechnologlaIndustrial (IGAITI) in Guatemala has been designated as theofficial standards organization to represent the CentralAmerican Textile Association, of which the five Central-Americancountries are members.
- 3 -
The agenda for the Seminar comprised 24 PASO Recommendations.The subjects of these had been decided upon at the 1963 Sem.inarof PASG/C6 on the basis of their meeting the Immediate needsof the textile industries of Latin America. The preliminarywork and the drafting of these Recommendations was mostcompetently accomplished by the Technical Secretariat and itsSubcommittees
.
Senora Le Roux de Carrillo^ adscript to the Direction ofINAlfPIC and PASC/C6^ was Director of the Seminar. The preparationfor the Seminar by INANTIC ^ involving^many details and muchwork^ was complete and excellent. Senora de Carrillo's splendiddirection of the Seminar^ and the seemingly tireless energyand friendliness of the entire staff of INANTIC ^ contributedimmeasurably to Its success.

3,3 AGENDA
The px’ogram for the Seminar consisted of 24 PASO DraftRecommendations on subjects proposed by the I963 PASC/C6Seminar as those which should be given priority because oftheir immediate usefulness to the textile industries ofLatin America, The drafts were prepared by the TechnicalSecretariat ( INANTIC ) and its Subcommittees, The majorityof these were based on previously submitted standards ofthe ISO, ASTM, AATCC, and to a lesser degree upon methodsof test developed by the Latin-American countries.
Before the Seminar, the Draft Recommendations werecirculated for review and comment within the member countriesof PASO by the national standards organizations in Centraland South America, Mexico and the United States. The commentswere then considered by INANTIC and the Recommendationsrevised accordingly. The revised Recommendations v^rere againcirculated for comment and review. The composite of commentsthus obtained represented the official opinions of the countriesrepresented and were those expressed by the respective delegatesat the Seminar.
The agenda comprised 24 Draft Recommendations: 7 on wool;10 on fibers and yarns; 2 on colorfastness, and 5 on cloths.Consideration was given to these In the order scheduled.
The agenda Is given in the Appendix,
3.4 OPENING OP THE SEMINAR
The formal inauguration of the Second Pan-AmericanSeminar on the Standardization of Textile Products was heldon October 26 at the National University of Engineering uponInvitation by Ing. Mario Samame Bogglo, Rector of the University,President of the National Comission of Technical Standards,and President Elect of the Pan-American Technical StandardsComm.lttee (CPANT),

The program was under the auspices of the Organizationde Estados Americanos (OEA)^ the Comlte Panamericano de NormasTecnicas (CPANT)^ and the Institute Naclonal de Normas TecnicasIndustriales y Certificacion ( INANTIC ) , It was interesting
j
Informative j and Inspiring.
Senor BoggiOj other eminent personages from the UniversityOEAj CPANT, and INANTIC presented brief addresses whichemphasized the success of the 19^3 Seminar. It was stated thatthe principal objectives of the Seminars are l) to acceleratePan-American standardization and^ 2) to make available in ashort time standards that permit commercial interchangebetween the American countries ^ facilitated by a technicallanguage common to all the American countries^ and soessential to the commercial transactions on both nationaland International levels. This second Seminar^ it was emphasized^is of the utmost importance in furthering and achieving theseobjectives
.
On conclusion of the program^, the guests and dignitarieswere guests of SerTor Boggio at a cocktail reception. It wasmost enjoyable and provided a relaxed atmosphere for furtherdiscussion and the initiation and renewal of friendships,
3.5 CONDUCT OF SEMINAR MEETINGS
Professor Juan V. Cabrerizo, Field Director of OAS,opened the first technical meeting of the Seminar saying thatthe work of the Seminar is that of an international committeestudying matters of great Interest to the continent. Heexplained that^ l) the Seminar would be conducted accordingto the OEA (OAS) and CPANT ( PASC ) rules 5; 2) that mattersdecided by the Delegation to be of Importance would be votedupon^ 3) that those making the decisions (voting) must bepresent at least 85 per cent of the tlmej 4) that each countryhad one vote (to be cast by the leader of the Delegation);5) that approval of actions and Recommendations requires aunanimous ballot; 6) that voting abstentions constitutenegative votes.
5A detailed account of the rules of conduct to which theSeminar conformed is given by this author in NBS report 8I96(1964);, available upon request.

The meeting was then turned over to Serfora de Carrillowho provided further information:
1 - The morning and afternoon sessions would conveneat 8:30 AM and 2:30 PM^ respectively^
2 - That Editorial Committees^ appointed to preparerevised drafts of Recommendations discussed duringthe dayj would meet at the conclusion of the after-noon meeting and remain in session until completionof the revision. (These hours ranged from 10-11 PMand sometimes 2-3 AM.
)
3 ” That an appointed secretary would write the minutesof each session which^ with the revised Recommendations.,would be available (in Spanish and English) for thenext day's meetings. (The fact that this was accomplish-ed is a credit to the long hours worked by the INANTICstaff,

Although the approval of the sampling plan wasunanimous, Brazil did so with the reservationthat further statistical study be made.
Approved was a proposal by Peru to circulateto all member bodies of PASO a standard sampleso that a study might be made to determinestatistically whether the results of measurementsare affected by using different specimen lengths.
PASC 6-003, WOOL - METHOD OP TEST FOR DETERMININGWOOL FIBER LENGTH USING A COMB SORTER.
This method, based on the Schlumberger apparatusused by the IWTO, was tabled pending Informationon lengths of Intervals to be obtained fromIWTO by the Technical Secretariat and thencirculated to the member countries of PASO.
Discussions on this Recommendation were animatedand extensive. Many opinions were expressed;the Schlumberger is practically unknown in theUnited States or in Latin America but (accordingto Mexico) used by the IWTO to arbitrate inter-national transactions of wool top; the Schlumbergeris already a part of a DGN Project Standard inMexico; the Schlumberger is in an ISO methodcorresponding to that of IWTO and, according toPASC principles, ISO procedures should havefirst priority. (Its status remains Draft lA.)
There was unanimous agreement that a method onthe Suter apparatus be written correspondingto ASTM D 519. (See PASC 6-007

This method, based on ASTM D 1770-62T, wasapproved as Project 1 following editorialmodification which included changing thelength ranges and segment of reference lengthfor vegetable matter. Figure 2 (ASTM), frominches to millimeters.
PASO 6-006, WOOL - METHODS OP TEST FOR DETERMININGWOOL CONTENT OP RAW WOOL (LABORATORYSCALE),
This method, based on ASTM D 584-57, was approvedas Project 1 after extensive editorial revision.
PASC 6-007, WOOL - METHOD OF TEST FOR DETERMININGFIBER LENGTH IN WOOL TOP.
This method, based on ASTM D 519-58 and theuse of the Suter wool fiber stapling apparatus,was written by the Editorial Committee uponunanimous vote of the Delegation following with-drawal of PASC 6-OO3 on the Schlumberger apparatus.Its development during the time of the Seminarwas permitted by the fifth article of the By-Laws of CPANT.
Following a continuation of the lively discussionof the Schlumberger vs the Suter apparatus, avote to approve this method as Project 1 wasdefeated: l)it refers to an apparatus andtechnique not studied in two of the membercountries of PASC and, 2) because, beforeapproval, it should be circulated for studyand review by all member countries. Thismethod was subject to minor editorial changesinclusive of substituting 10-mm class intervalsfor 0.5-in. intervals in Table I. It finallywas approved as Draft 1 so that it may receivefurther study before advancement to Project 1.
PASC/C6 requests the ASTM to provide the D 519“photograph required. (Granted.)

This method, based on a method of the ShirleyInstitute, was approved as Project 1 aftersome discussion and extensive editorialrevision. The major modifications were:limiting the method to the Shirley analyzerjinclusion of a statement that the definitionsincluded are "for purposes of this Recommendation"modification of Tables I and II on the speedsand settings of the analyzer; classificationand expansion of the chapters on sampling andprocedure; and addition of a statement onprecision as related to raw cotton.
Following approval by the Delegation to retainparagraph 9»1«2,7 on residual lint, as givenin Draft Recommendation 2, the Chairman requestedthat all delegates discuss it upon return totheir respective countries, in preparation fora final "yes" or "no" vote when the Recommendationis submitted to their countries for approvalas a PASC Standard.
PASC 6-037 , YARNS - METHOD OF TEST FOR THEDETERMINATION OF BREAKING LOADAND ELONGATION (SINGLE YARN METHOD).
Because of the many objections to this method,it was withdrawn. After much discussion ofan ISO method (considered a project) and studyof ASTM D 2256-64, it was agreed to draft anew method based on that of ASTM, The develop-ment of this method during the time of theSeminar was permitted by the By-Laws of CPANT.
This new method, "YARN - TENSILE TEST FORSINGLE YARNS", was approved as Project 1.It IS not applicable to yarns made from fiberssuch as asbestos, glass, flax, hemp, ramie,kraft paper, or to products such as cords fortires and cables.

This method, although finally approved asProject 1 , was the subject of intense andprolonged discussion revolving around;expansion of the Scope to include detei’mi-nation of moisture of all fibers (rejected);deletion of the alternate method on the useof the dessicator (rejected); addition of achapter on sampling of fibers, yarns, andother products not covered by existing drafts(rejected).
The method as approved contains a number ofchapter modifications and editorial changesto be incorporated by the Technical Secretariatprior to Its future review.
Because of the diverse opinions expressedduring the discussions, the strong plea ofUruguay for a method with an expanded scopeand sampling plan, the information made avail-able on a method used successfully in Brazil,and the offer of Mexico to collaborate on thepreparation of another method (on "lota" offibers and yarns, and to include sampling),a technical committee vi?as appointed to preparethe draft. The committee was chaired byUruguay and assisted by Mexico, Argentinaand others who prepared the draft after hours.
The resultant method, DETERMINATION OP MOISTURECONTENT IN COTTON BALE LOTS, with additionalinformation to be supplied by Uruguay and Brazilwas submitted to the Technical Secretariat forits later presentation as Draft Recommendation 1 ,

This method, based on ASTM D 2495-61T, wastabled because no agreement could be reachedon the instrument to be used. Discussed werethe causticalre^ microscopic counting, anddifferential dyeing techniques, although thelatter is not considered by the United Statesto be an indication of maturity.
The method was returned to the TechnicalSecretariat for redrafting using as referenceB. S, Standard 3O85,
PASO 6-040, YARNS - METHOD OF TEST FOR UNEVENI^SSOF YARNS, YARN INTERMEDIATES, ANDSIMILAR PRODUCTS.
This method was tabled to permit further studyfollowing discussion of the Uster evenesstester, a Hungarian apparatus said to be similarin principles and results obtained, and otherevenness devices such as the Fielden and Brush.
Although the Uster was acceptable to everyone,agreement was reached to redraft the methodto include devices other than the Uster onlyif they give the same or equivalent valuesas the Uster; if not, the revision is to bebased on the Uster and the ASTM procedure.
The preferred sources of Information wereagreed to be ASTM D l425-60T, an ISOTentative Recommendation, and the Uster manuals.These are to be turned over to the TechnicalSecretariat for evaluation and use in thepreparation of the method indicated,
PASC 6-029, FIBERS - METHOD OF TEST FORDETERMINING THE LENGTH OF COTTONFIBERS BY MEANS OF COMB CLASSERS.

It was agreed, upon a proposal by Argentina,to include in this method the trade namesof fibers common to Latin America when andas they become available.
SUMMARY: SECTION II
Of the 10 Recommendations considered^ 7 were approvedas Project 1^ 2 were tabled for further study and revision^and 1 was withdrawn. The significance of these standardslies in their being of practical value to the textile millwhether used in quality control or as bases for the buyingand selling of man-made and cotton fibers and yarns.
3.6.3 SECTION III; COLORPASTNESS^ FABRICSChairman; Senora Le Roux de Carrillo
DatesDiscussed Recommendations; Modifications of; Actions on
11/10,11 PASC 6-030, COLORPASTNESS - TERMINOLOGY,DEFINITIONS AND GENERAL PRINCIPLES.
This Recommendation, prepared by the TechnicalSecretariat, was an extension of ISO R 105,Part 1. After much discussion and revisionto a Recommendation titled COLORFASTNESS -
GENERAL PRINCIPLES OP TESTING, a counterpartof ISO R 105, Part I only, it was approvedas Project 1.
The reasons for this modification and revisionare explained in subsequent paragraphs.
There was much discussion of the first draftand a lack of enthusiasm for it. Argentinaproposed its replacement by one it submittedto the Technical Secretariat (in Spanish)and also based on ISO R 105, Part I, butnumbered according to the PASC system; theUnited States stated it considered the titlemisleading and that the deviations from theISO document present in PASC 6-O3O detractedfrom its value, and did not cover, as indicated,terminology and definitions.
-l6-
DatesDiscussed Recommendations: Modifications of; Actions on
PASO 6-O30 (Continued)
Although discussed, there was no agreementon the suggestion to revise PASO 6-03Ointo two Recommendations; Argentina express-ing a desire for action on the Argentinedraft before drafting a Recommendation ondefinitions, and the United States maintain-ing a preference for a revision of PASC 6-O3Obased only on Part I of ISO R I05.
Following a United States proposal "thatPASC/C6 accept ISO R 105^ Part I (verbatim)to replace PASC 6-O3O and to considerterminology and definitions as subjects fora new standard at a later date" (Approved),and the proposal of Argentina "that theArgentine draft be translated into Englishand be studied during the Seminar" (Approved),the Chairman appointed an Editorial Committeeto translate and compare the Argentine draftwith that of the ISO and to prepare the revisedRecommendation in collaboration with theUnited States.
The resultant Recommendation PASC 6- 03Otitled COLORPASTNESS- GENERAL PRINCIPLES OPTESTING is synonymous with ISO R 105^ Part Iexcept that it conforms in form and decimalnumbering system to that of PASC. It wasnoted that the only definitions included arethose pertinent to its understanding.
Of additional interest to the reader m^ bethe statement made by the Chairman, Senora deCarrillo, during discussions on colorfastnessterminology and definitions, that a newStandard on this subject would be submittedin the future; that a Technical Sub-Secretariatis already working on its preparation.
The United States informed the Delegation thatword had Just been received by cable of itsacceptance of the Sub-Secretariat on Color-fastness, and was extremely pleased to havethis responsibility.

Recommendations; Modifications of; Actions on
PASO 6-015, COLORPASTNESS TO BLEACHING WITHHYPOCHLORITE
Background Information .- This Recommendationwas considered during the I963 Seminar atwhich time agreement could not be reachedon the method because of the differences ofopinion regarding the test temperatures;substitution of the AATCC test temperatureof 27 ± (proposed by the United States)for the 20 ± 2®C specified by the ISO, theUnited States maintaining that the formerwas more representative of the alterationfactor which takes place in practice.
As a result of the lack of unanimity, them.ethod was tabled and a decision made toconduct experiments to compare the AATCCand the ISO test methods employing thesetwo temperatures, the Technical Secretariatto conduct the study.
In the summer of 1964 PASC 6-OI5 wasdistributed to the member countries of PASCfor approval as a PASC Standard. The UnitedStates cast a negative vote, not havingreceived word or results of the experimentsin question.
Upon arrival at the 1964 Seminar, the U. S,Delegation was informed that both the AATCCand ISO methods had been studied, and thatthe results had been circulated to themember countries of PASC informing themof the favorable results obtained withthe AATCC test temperature.
Action at the Seminar . - The Chairmanexplained to the Delegation that the approvalof PASC 6-015 is pending due to the negativevote cast by the United States because, forreasons unknown, information was not receivedon the Technical Secretariat's studies whichshowed no significant differences in theresults obtained using AATCC and ISO testtemperatures

This method was approved as Project 1,following much discussion and both technicaland editorial revisions.
The basic changes in the method were:providing for the use of cut and un-cutspecimens j providing two procedures, adirect-counting and a ravel method, forcounting yarns per inch, the second to bedesignated as the reference method;specifying that 3 warp and 3 filling specimensbe tested from each test sample; deletionof chapter 5 on "sampling and inspection"except for relocating paragraph onpreparation of the specimen.
Interest was expressed in developing, forfuture needs, a similar standard applicableto circular and warp knits,
PASO 6-033^ CLOTHS - METHOD OF TEST FOR THEDETERMINATION OF BURSTING STRENGTH.
This method, based on manufacturers Instructionson the Schiller machine, was withdrawn: itwas thought not a good method; sufficientinformation was not available on it; it wasconsidered unsuitable for use in LatinAm.erica,
Although it was pointed out that there isnot yet a Subcommittee on Knit Goods, theDelegation favored developing a diaphragmbursting strength method for knit goodsbased on one distributed last year(Method 5122 of U. S. Federal SpecificationCCC-T-191b). Accordingly, a proposal was
approved to remove PASO 6-033 from theagenda and send it to the Technical Secretariatwith the suggestion that its revision beconsidered in 1965,

This method, the complete revision of whichwas based on ASTM D 1682-64, was approvedas Project 1, titled FABRICS - TENSILE TESTS,following extensive discussion on the testingrequirements considered essential.
The revised Recommendation, prepared by aspecial Technical Committee, establishesgrab and ravel-strip procedures for determiningthe maximum load and elongation of wovencloth, based on the use of CRT and CRE machines,respectively.
PASC 6-042, CLOTHS - METHOD OF TEST TO DETERMINEWATER PERMEABILITY.
Because of general dissatisfaction with thismethod it was withdrawn as not being applic-able to the needs of Latin America.
Discussions of water repellency indicatedthat the spray, hydrostatic, and droppenetration methods were those used chieflyin Central and South America,
The submission and discussion of two tests,Spanish versions of AATCC Standard TestMethods 18-1964 and 22-1964, resulted inthe approval of a proposal by Argentinathat these tests be given the status of"Schemes*', They will, consequently, besubmitted to the Technical Secretariat forstudy and action according to PASC procedures.
These new "Schemes", considered suitable foruse in Latin America are;
PASC 6-046, CLOTHS - METHODS OP TEST FORDETERMINING WATER RESISTANCEBY THE HYDROSTATIC PRESSURE METHOD.(AATCC Standard Test Method 18-1964)
PASC 6-047. CLOTHS - METHODS OF TEST FORDETERMINING WATER REPELI.ENCE(ARTIFICIAL RAIN METHOD), (AATCCStandard Test Method 22-1964)

SUMMARY s SECTION III
Of the 7 Recommendations considered, five wereapproved as Project 1, 2 were withdrawn because notapplicable for use by the textiles industries ofLatin America, and 2 new "Schemes " were drafted. Theacceptance of these Project -1 Recommendations as PASOStandards will make available to the Latin-Americantextile Industries procedures for determining theconstruction, colorfastness to bleaching, and strengthand elongation of fabrics. Their use will make possiblean Improvement in the quality and uniformity of fabrics,

3.7a ROUND TABLE DISCUSSIONS
Wool
A round table discussion, chaired by Senor Goyret,the Uruguayan Delegate, was held on October 31* Itspurpose was two-fold, l) to discuss the length of fiberscut by the microtome, for inclusion in 6, A,
3
of PASO 6-002ProJect-1 Recommendation, and 2) to discuss subjects tobe prepared for 1965 standards on wool, these to constituterecommendations for the working agenda of the PASC/C6Subcommittee on Wool,
The discussion of fiber length vs fineness, and ofthe length cut by the microtome, was extensive and wasresolved by l) a suggestion that the statistical aspectsof varying fiber length be the subject of interlaboratorystudy, and 2) a ^recommendation that the length cut by themicrotome be 0,5 mm.
Eight subjects for standards were unanimously approvedfor recommendation to the Subcommittee on Wool as a workingprogram for 19o5o

The development of tentative specifications foralpaca types according to fineness constitutes the I965program of the Subcommittee on Camel Hairs.
PASC/C6 Seminars
A Preliminary Report on PASC/C6 Seminars ^ presentedon November 2 by Mexico^ ICAITI^ Argentina^ and Uruguayresulted in a round table ^ chaired by Senhor Von Rankeof Brazil. The principal points brought forward were:provision of English translations during technical sessions;2) that all countries should be consulted and participatein the preparation of first drafts; 3) that^ in future^only 1 draft should be considered daily^ its basic pointsin plenary sessions j, and its editorial revision in EditorialCommittees; 4) that plenary sessions be held in the morningsand Editorial Committees in the afternoons; 5) that the workprogram.s for the next year be prepared by the current Seminarand that it Include subjects for standards needed for freetrade and industry; 6) that some consideration be given toa Seminar sponsor for I965. (We had been informed that OASProject 207 is ended, )
An interesting and constructive point - by-pointdiscussion ensued. It was emphasized that: 1) countriesshould be consulted on all basic points before drafts areprepared; that this had been attempted in 19^3 when theSeminar proposed the I964 agenda and decided upon the basictechnical points for "Schemes"; 2) that the proposed agendawas that approved by the General Secretariat of PASC; 3)when the agenda for the 1964 Seminar was distributed by theGeneral Secretariat ^ only Chile and Brazil replied; 4) thatwhen the subjects for 1964 drafts were distributed to themember countries of PASC by the Technical Secretariat,requesting all related technical information, replies andInformation were sent only by Chile and the United States.(Communication problems were shown to be partially responsiblefor non-receipt of the request.)
It was agreed that l) in future a deadline be set bythe Technical Secretariat for the receipt of informationrelated to subjects for drafts; 2) that, upon receivingthis information and related material, priority will beassigned; 3) should comments not be received by the datespecified, the Technical Secretariat may assume that approvalis given by the country or countries in question.

This discussion brought to the attention of eachDelegate the intricacies, problems, and inter-relationof many facets of the Seminar form of meeting. A betterunderstanding of the cooperation and work required resulted.The report which led to this round table, the opinionsexpressed, and the concensus of the Delegation werereferred to Professor Cabrerizo, Field Flrector, forimplementation

3.7o2 VISITS TO FACTORIES AND LABORATORIES
Factories
Scheduled visits were made to three large, modern,and well-equipped mills where the Delegation obtainedfirsthand Information on plant layouts, equipment, andmanufacturing processes. In each mill all stages ofmanufacture, from raw material to finished product, wereperformed. We were impressed with the excellent equipment,laboratory facilities, versatility, and large productionof each mill. It was interesting to learn that only newmachinery may now be purchased for expansion or replacement,and that another economic burden is the difference inworking hours of employees: 7 hours daily for women, andeight for men.
Sincere appreciation is extended to the executivesof the following mills for their cordiality during our visits
Cinsa Woolen Mills (llama, alpaca, and blends:llama/alpaca; alpaca/reworked wool)
Santa Catalina Worsted Mills (worsted and worsted/cotton blends)
Textil Algodonera S, A. Factory (cotton)
Laboratories
Laboratorio de Lamas, Programa de Qvlnos y Alpacas ,
Unlversldad Agrarla .- The Delegation, on October 31
j
visited the Laboratorio upon invitation of S^nor JuanVlllarroel, Director of the Alpaca Laboratory and aPeruvian delegate. The tour of the laboratories, theinformation obtained on the correlation of field work andresearch, the improvement in fleeces and yield resultingfrom the introduction of mechanical and yearly shearing, abrief account of the new program planned for testing alpaca,and an exhibit of wool and alpaca fiber and yarns, andvicuna fabric made this a most pleasant, rewarding visit.

The hospitality of Senor Villarroel, the Head of theDepartment of Animal Industry Technology and the Dean ofAgriculture of the Universldad Agraria, and the staff ofthe Laboratorio, as well as the very delicious al frescoluncheon served on the lawn contributed immeasurably toour enjoyment,
Laboratorio de Came .- Following the tour of theAlpaca laboratories j, the Delegation visited the enclosuresof laboratory cattle ^ hogs^ rats, and chickens and thenthe experimental sections of the Laboratorio de Game,located on adjacent grounds at La Molina.
We were fascinated to hear of the very importantresearch on fish and on cotton seed meal conducted toalleviate the chief dietary problems in Peru: lack ofcalories and protein. Fresh fish (abundant in Peruand treated chemically to destroy the fish taste andodor) is fed to hogs and chickens instead of fish mealwhich is more expensive. The Laboratorio is studyingits effect on the nutritive value and quality of theresultant products. The Delegation was shown linkedsausage made from, hogs given fresh fish (treated withchemicals), and was told one could not detect a fishorder or taste when eating them.
Other research was in progress on feeding concentratesof cotton seed meal plus vitamins to rats, the objectivebeing to develop a baby food (needing only the addition ofwater) to provide a cheap source of calories and vitaminsfor the many people for whom the availability and cost ofmilk made its use impossible. Tnis research is both essentialand humanitarian.

4. DISCUSSIONS; PAN-AMERICAN STANDARDIZATION ACTIVITIESIN CENTRAL AND SOUTH AMERICA
4.1 GUATEMALA CITY, GUATEMALA; UNITED STATES EMBASSY]ICAITI
The organization of the Central American TextileAssociation, under the leadership of ICAITI, was completedin the early summer of 1964. Consequently, it is a greatpleasure to knov/ that the Central-Amerlcan countries are,through ICAITI, cooperating fully in the standardizationactivities of PASC. This was evident at the Seminar andwas comjTiented on most favorably during a very pleasantconversation with Mr, Jay Phillip Freres, Second Secretary,U, So Em.bassy,
A most cordial and Informative morning was spent atICAITI with Dr. Manuel Noreiga Morales, Director. Sefiorhnnllermo Gonzales GSmez. Assistant to the Director, Dr.Pio Gonz'S.les, Director ^of the Standardization Division,Senorita Rocio M, Marban and Senor Roberto Arriola de Leon,
From discussions and observations, I ' learned l) thatthere is a tremendous Increase in activity at ICAITI’ andin Central Am.erica since the formation of the CentralAmerican Textile Association^ 2) that, in
-31-
cooperation with the Agricultural Department, Guatemalaand other Central -American countries are growing andstudying new breeds of cotton having longer length,greater fineness and strength; 3) ICAITI has a pilot plantfor studying cotton length, an excellent small laboratoryfor studying the drawing, drafting and spinning of cotton(this, under Senor Arriola), a new paper laboratory (usingTAPPI and German standards), and a food laboratory whichis studying the drying, concentration, and processing offresh fruits and vegetables with the object of expandingthe market for these products and thereby increasing theeconomy in this area,
I saw the well-stocked general library and alsothe standards library, both of which are expanding.It was gratifying to hear that the NBS Journal ofResearch and NBS Technical News Bulletins (in which aninterest was expressed last year on an exchange basis)are being received.
At the time of my visit. Dr, Pio Gonzales mentionedthat the duplicating and printing problems are the sameas those of last year. His request for Information onspecific printing m.achines and for standards for aeronauticalmaterials, in which his Division is interested, have beencomplied with since that time.
It was a disappointment to me that Dr. Ing, EberhardSchafer, former United Nations Technical Advisor to theTextile Industry, had left Guai^emala for a temporaryassignment to the Institute de Pomento Nacional in Managua,Nicaragua, and so was not available for my anticipatedappolntnjent . Because it was impossible to acceptDr. Schaefer's cordial invitation for a meeting in Nicaragua,and because of my interest in the current developments andfuture prospects of the textile industry in Central America,Dr, Schaefer had delivered to me in Lima a copy of the"Programa de Desarrollo de la Industria Textil de Hilados yTejidos Pianos de Algodon", a very excellent and comprehensivereport.
4,2 LIMA, PERUs UNITED STATES EMBASSY
Several very cordial meetings with Mr. Frank A, Mau,Second Secretary, took place during the weeks of theSeminar, each providing an opportunity for the writer andother U, S, delegates to talk with him on the textilestandardization program and various aspects of the textileindustry in South America,
-32 -
It was pleasant to renew my acquaintance of I963and to hear from Mr, Mau praise of the expanding knowledgeof^ and interest in, the standardization activities ontextiles manifest throughout Latin America.
Prom Mr, Mau and the Agricultural Attache, Mr, Traeger(who also gave generously of his time and knowledge wcohta.ined a great deal of Information on the cotton industriesof North and Central Peru, the impact on production of theincreasing number of hydro-electric plants in making moreland available, and Government regulations on the plantingof cotton, fruits, and vegetables. We were told thatcotton Is planted first and then some of the landconverted to corn which will provide 2 crops a j^^earj thatone must plant Ip-lS percent (of land) in fruits andvegetables, and that one is fined if more are planted]that often this law is violated, the fine is paid, and onemakes a profit.
Discussed also during these visits were: the newUo S, cotton price vs its affect on manufactured products;comparison of American Upland, Peruvian , and Egyptiancotton quality] the origin of textile machinery used inArgentina, Brazil, and other South-Am.erican countriesvisited by several of the U. S. delegates.
To all of the persons visited in Guatemala City andIn Lima, I extend my sincere thanks for their hospitality,time, and information so graciously given.
