Internship report on “An overview of Antim Knit Composite Ltd”. Project report on “Polyester/Cotton Fabric Blends Dyeing”

Abstract

This project is on “Blend Dyeing on Cotton/Polyester fabric with disperse & reactive dye”.This is a dyeing process where polyester part with disperse dye and cotton part with reactive dye.The experiment was conducted in the laboratory of DIU, Department of TE & lab of NTL. The aim of this project is to dye the fabric with disperse, carrier method & reactive at60 degree centigrade in textile processing.‘The use of salt & soda makes the effluent toxic for the environment. In conventional method of dyeing on cotton fabric with reactive dyes, alkali pH should be maintained in bath. This method requires more electrolytes for exhaustion and fixation.In this project, fiber modification technique based on polyacryl amide has discussed. Color fastness test is done after dyeing the cotton & polyester fabric. It is to be hoped that by the end of this thesis paper the reader will have a better idea about “Blends dyeing 0n cotton/polyester fabric with disperse & reactive dyes”.
