Sustainable Development

Sustainable Development was originally definedby the Brundt land Commission in 1987 as

Meeting the needs of the present generation, without compromising the ability of future generations tomeet their needs .


4/50


This definition usually comes with the footnote that itencompasses environmental, economic as well associal needsIn this context industry has the dual role ofsupporting and counteracting sustainabledevelopment at the same time

Support is provided by industry through its role aseconomic motor, employer, provider of infrastructure,supporter of education, health care etc.

SUSTAINABILITY

Need to believe in environmentalsustainability taking incremental steps in

supply chain processes to make it happenNeed to be aware about the social,economical and ecological benefits ofenvironmentally sustainable products anddevelopment processes.


7/50

Care for the Environment

Influence the supply chain to use SustainableProcessesRun business operations in an environmentallyfriendly wayWork to conserve energy and reduce waste.Sustainable design approach - Explore and

implement sustainable materials and products.

Eco Textiles


20/50

Back Ground

Measurable improvement in sustainability

Key element and areas in the textile production chain

Economic, social and environmental aspects ofsustainability

Proper selection of dyes and chemicals.


21/50

Sustainable Textile Fibers

Establishment of third party certification

Dystar anticipate these challenges

They introduce the new Eco fibers

Which help in a solid formation of textile industry


22/50

Organic Cotton

More sustainable choice of todays

Globally established standards

First choice for the brands and retailers


23/50

Dystars Efforts Towards OrganicSustainability

Developing and implementing the global organictextile standard (GOTS)

Leading global supplier of dye for cellulosic fibers

Responsible for environmentally friendly dyestuffproduction

Wide range of shades by all application methods.


24/50

Bamboo Fiber

Natural fiber

A quick-growth plant

Renewable plant

Doesnt need pesticides or fertilizer during growthphase

Three method by which bamboo produce


25/50

Bamboo Fiber

1. MECHANICAL PROCESS

2. CHEMICAL AND MECHANICAL SPINNERTS

3. CLOSED SOLVENT SPINNINGLOOP

Bamboo can be dyed with all dyes recommendedfoe cellulose fibers

But for Eco friendly purpose it should be selected

Recycled Polyester

Two kinds of recycled polyester are available onthe market

1. Mechanical recycled polyester

2. Full chemical recycled polyester


28/50

Organic Wool

Different from conventional woolTwo major factor

1. Sheep cannot be dipped in insecticides2. Organic wool formers do not exceed the natural

carrying capacityDystar recommends in GOTS-approved EHFreactive dyes for organic woolGOTS approved wool auxiliary chemicals areavailable

SUSTAINABLE TEXTILE WETPROCESSING


30/50

Wet processing

Important environmental concerns relatedto textile wet processing:Chemical intensive wet processing scouring,

bleaching, mercerizing, dyeing , printing etc.Heavy metals iron, copper, lead etc, found indyestuffs auxiliaries, binders etc.Residual dyestuffs, chemicals in water: due to

poor fixation of colors.PVC and phthalates: used in plastisol printingpaste.Formaldehyde : found in dispersing agents,

printing paste and colorant fixatives.


31/50

Sustainable Processing

Textile wet processing using environmentally friendlyagents and sustainable methods of processing inorder to have environmentally safe processing withless chemicals inputs and problems in effluentdisposals etc.(e.g., use of peroxide bleaching, natural dyes, azofree dyes.)


32/50

Sustainable Processing of Textiles

Exp lor e in to Bio P roc ess ing of T ex tilesB io-processing can simply be defined as the

application of living organisms and their componentsto industrial products and processes, which aremainly based on enzymes.B io processing also offers the potential for new

industrial processes that require less energy, lesswater and less effluent problems with effective

results.Enzymatic DesizingEnzymatic ScouringEnzymatic B leachingB io polishing and Enzyme based softeners etc.

Back GroundTextile industry is the most polluting manufacturingindustries in the world

Textile processing generate air, water and soilpollution through often untreated-effluent

In order to achieved reduced load on environment, weneed to optimize and standardize the entire supplychain & resources


36/50

Sustainable: Exhaust Dyeing

Reactive dyeing of cotton fabricMain effluent is TDS, COD, BOD, colour and pHConcept of RFT (Right-first-time)Use of Remazol Ultra Reactive dyesThis dyes have following advantages

1. Tinctorial strength

2. High fixation3. Minimize dye blocking
