Abstract:

Extraction of natural dyes for the coloration of textile substrate is one the most important research area to the researchers. These dyes are considered to be very good for their colour experimentation quality, excellent for their endurance and soft lustrous colouring. They do not create any pollution problems as they are applied with simple chemical reactions. The wide verities of exotic shades produced by natural dyes are parallel with the synthetic range and hence can replace them with ease. Natural dyes are being considered as a more environmentally friendly substitute for synthetic dyes. The major advantage of natural dyes is the fact that they are produced from renewable sources. Among the few drawbacks of natural dyes low colourfastness property is one. It was tried to improve the Crock Fastness and perspiration fastness Properties of Annatto natural dyed cotton with eco-friendly dye fixing agents. In this research, after mordanted and dyed samples were treated with fixing agents which are helped in fixation of natural dyes on fabric. The 100 percent cotton fabric was selected and desized to remove starch from fabric. Then the fabric was pretreated with morobalan solution for 24 hours. As mordant, Potash Alum [K2Al2 (SO4)3.24H2O], Stannous Chloride (SnCl2) and Ferrous Sulphate (FeSO4) were used. Here pre-mordanting was used for mordanting the fabric. The mordanting procedures were followed same for all the experiments. The treatment runtime was 30 minutes at 600C. After mordanting each sample fabric was dyed with annatto seeds dye extraction for 45 minutes. After dyeing, all the samples were post-treated with five eco-friendly dye fixing agents such as alum, ammonia, lime juice and calcium chloride. Five percent fixing agent was selected and kept the dyed fabric in the solution for 30 minutes. Finally the fabric samples were cold rinsed and soaping was done and dried. Finally the color fastness like Color fastness to crocking and Color fastness to perspiration were checked and found satisfactory result.
