Quick wash denim: Quick wash denim fabric is dyed with modified
technique of dyeing. So that during wash cycle, indigo dye can be removed
quickly. Giving washed look at shorter washing cycle. This results in more
economical washes i.e. low water consumption, less usage of chemicals, less
time and retaining fabric strength.
Tinted denim: With increase in demand of tinted/ over dyed look on
garment, garment processor is using an additional process of tinting/over
dyeing, which is time consuming. It consumes large quantity of water and
chemicals. It is also associated with the risk of patches and unevenness on
garments. Now the denim fabric is also available in tinted form which saves
processors time and risk.
Grainy look denim: Different chemicals and processes are used to get
grain look on the denim garments. To meet this requirement special denim fabric
has been developed which gives grainy look after processing of denim garment
Soft feel denim: To meet such requirement, different varieties of denim fabric
are available, which are having inherent softness. These fabrics require
minimum application of softener at the garment stage.
Recent Developments in Garment Processing:
It was considered impossible to obtain wrinkle free finish
on white garments in wet processing. It was rather difficult to achieve
wrinkle free performance with minimal yellowing and strength loss, and good
handle. Achieving any of these attributes implied compromising on the other
two. Now, thanks to recent product developments, it is possible to strike a
good balance between these features, with the help of a wrinkle-free system
containing an inbuilt catalyst and softener.
Also, microencapsulated fragrance finishes are becoming
important value-adds in garment processing. When these finishes are applied on
to the garments, in the same way as perfumes, the active ingredients get
gradually released on to the skin.
Laser-based processing is another emerging versatile
technology in denim finishing, which permits application of laser-based
photographic effects, abrasion effects and new laser-based stone washes.
Recent developments have also made it possible to use
antimicrobial finishes, water and oil-repellent finishes, flame-retardant
finishes, antiozonate finishes, UV absorber finishes and coatings individually,
and in combinations of two or three.
Avoiding the Environmental Hazards of Garment Processing:
Textile processing uses vast amounts of water, chemicals and
energy, and therefore, has considerable effects on the environment in the
textile manufacturing regions. The effluents from wet processing of garments
cause similar environmental hazards as fabric processing. Moreover, the garment
processing sector is highly unorganized; effluents are released in to municipal
drains causing environmental problems.
Apart from investing heavily in effluent treatment,
pollution loads can also be reduced by 30-50%, by using pollution prevention
techniques. Heres list of wheat can be done.
1)
Reduce
wastewater volume by:
• Good
housekeeping
• Counter flow
processing
• Re-using process
water,
• Automating
machinery,
• Processing
alternatives i.e., green cleaning over conventional dry cleaning where
perchloroethylene is replaced by CO2 in liquid state,or by organic
hydrocarbons, ozonated water and ultrasonic cleaning.
2)
Reduce the
amount of dyes and chemicals used by:
• Good
housekeeping
• Process
optimization,
• Recovery and
re-use of process chemicals,
• Automation of
machinery,
• Replacement of
conventional chemicals with eco-friendly chemicals.
The dyestuffs, pigments and chemical products saved by
these methods mean less effluent in the system.
