3.5 Selection of Appropriate Finish on Protective Clothing
for Petrochemical Industry
The chemicals selected in the research process were ecofriendly, sustainable, and
feasible in terms of cost and availability. Also, according to research on indigo dyes
and current course of research results, it was found that the use of indigo dyed fabric
would make it essential for long-term usage. Application of anti-microbial finish on
indigo dyed denim ensures additional resistance to microbes.
3.6 Flame Retardant Property
The qualitative assessment of flame retardancy of the denim samples was carried
out. The flame-retardant properties were compared with the control sample here,
and it was found that the finished sample bare excellent results in all the weights of
fabric. As far as fire catching was concerned as per ISO 15025, all the combinations
exhibited an excellent rating with no flaming on vertical or horizontal edge, no after
flame, nil in afterglow spread, no occurrence of debris observed, and hence, no debris
that ignites the filter paper nor hole development in multilayer specimen.
3.7 Selection of Appropriate Finish on Protective Clothing
for Welding Industry
From the preliminary experimental work for anti-microbial, flame-retardant finish in
the last section emerged as the optimum option followed in the protective clothing
for welding. During the course of work, it was found that finish applied for moisture
management had to be withdrawn from combinations because of the decrease of
water vapor permeability value in the results. The presence of moisture management
finish with organo-phosphorous compound rendered not much absorption of moisture/water vapor. Thus, moisture management finish was not used for further study.
In this view of development, the next finish from comparative assessment of three
anti-microbial and one flame retardant finish was taken up.
Thus, it was evident that the combination anti-microbial [Sanigard 7500 (L.N.
Chemical), Fabsheild AEM 5700 and Microban PB 80150–050 (Rossari Biotech
Limited)] and flame retardant (organo-phosphorous compound, i.e., Glogard CP
new); anti-microbial and stain release [Aquarepel XC-630 (L.N. Chemical)] offer a
good option for a durable anti-microbial and flame retardant; anti-microbial and stain,
oil release finish applicable on 100 % cotton denim fabrics. Addition of Fixer ALN to
the finishes improves its durability to laundry. The chemicals used do not adversely
affect the other properties. The garments were found to be effective against microbe
penetration, flame or fire spark penetration, and stain or oil releasing, as shown by
