Abstract

Sumithra M and Arasi D

Nylon is a synthetic fiber made from petroleum products which was developed as an alternative to silk. Nylon is valued for its light weight, incredible tensile strength, durability, and resistance to damage. It also takes dye easily, making the fabric available in a wide array of colours for consumers. Nylon has conventionally been dyed by using Acid dyes on a major extent. In this study Nylon 6,6 was dyed with commercial di-chlorotriazinyl reactive dyes .using 100% nylon woven fabric was taken for this study. Nylon fabric GSM was 50 g/m2, EPI-20 and PPI-32. The pH was kept at 4 and the temperature was maintained at 98°C, this temperature was used in subsequent experiments. The blue reactive dyes and acid dyes are used for dyeing and it was concluded as good to excellent fastness to washing and rubbing. And light fastness was almost equal for both reactive dyed and acid dye. In acid and reactive dyes Blue MR had good colour variation,good colour strength.
