Calculation Method
Example: Front yarn 30s 100% cotton Back yarn 16 s 50:50 P/C Consumption ratio
Front Two kgs Back one kg
Total consumption three kgs Total consumption three kgs Calculation: Calculation: front yarn 2 kgs 100 % cotton Back yarn 1 kg ( ½ Kg polyester and ½ kg cotton Total Cotton consumed 2 + 0.5 =2.5 Kgs Total polyester consumed ½ kg Ratio: cotton= 2.5/3*100= 83.33% Polyester= 0.53*100=16.66% Such ratio is normally called 80:20 Fleece
Main characteristics of Main characteristics of ThreeThree Highly absorbent High weight is possible Can use entirely different yarn on both
sides( even dyed yarn) Pattern is possible ( diagonal stripes etc) Very common in use
Fleece problems and their Fleece problems and their remedies remedies Uneven loop – control yarn supply Loop stretch– control cam tension Needle line on front side Wales thickness variation on front side due to
fluff contamination between the needles, needs regular cleaning, more cleaning is required due to course yarn
Poor brushing–due to high TPI yarn– use low TPI
Dyeing variation due to different percentage of yarn… calculate exact % by using Skelton test
Steak problem after dyeing due to heavy weight fabric--- use anti creasing agents in dyeing
High shrinkage --- use compactor or tumble dryers
