the laboratory results. Special design feature was incorporated to ensure adequate
protection against hazards and better carrying capacity for tools and other things.
The use of protective clothing is essential for the protection of workers in the process
and OEM industries. Use of protective clothing developed is also recommended for
workers in any other chemical industries.
4 Conclusion
The salient findings of the experimental work undertaken for the selection of
appropriate finish and preparation of the finishes applied on denim were as follows:
• 100 % cotton denim and its 3/1 twill weave structure gave good durability which
was observed to be long-lasting as compared to the blends with polyester and/or
spandex that are currently and easily available in the market.
• Indigo dyed samples proved to give inherent anti-microbial properties that were
long-lasting and better than that of reactive dyed samples.
• Denim washes for aesthetic appeal may reduce the amount of indigo dye in
the fabric, which may or may not reduce the anti-microbial effect; hence, antimicrobial finish application was made primary in the research, resulting in 99.99 %
resistance and more than 85 % resistance even after 5 wash cycles.
• Application of two finishes opposite in nature (moisture management and flame
retardant) resulted in lowering of water vapor permeability. Hence, considering
moisture management as one of secondary finish was not accepted.
• It was observed that the flame-retardant property and moisture absorption was
better without moisture management finish, probably due to use of 100 % cotton
denim fabric.
• Application of finishes on 9 and 11 oz resulted in most suitable values for
protective clothing regarding comfort and textile handling properties.
• Other textile properties such as air permeability, thermal conductivity, tensile
strength, tear strength, and abrasion resistant increased significantly in 13 oz,
which made the denim heavier.
• Incorporation of Fixer ALN in flame retardant and stain release finish improved
its durability to laundry up to 20 wash cycles, which is recommended as per the
Indian standards.
• The evaluation of protection of finished fabrics against test methods was carried
out using standards IS, ISO and AATCC. A marked improvement in every property
was observed.
