Study of the effects of dyeing process with reactive dyes on cotton Knit fabrics

Abstract

Dyeing is one the most important part in the textiles manufacturing. Various types of fabric coloration are performed in dyeing section based on the requirements and demand of the buyer. Lots of traditional dyeing processes are running industrially in different manufacturing unit to dye the fabric. Different dyeing factories perform different dyeing process. But all of the dyeing processes are not practically suitable for the coloration of the fabric to maintain the exactly required shade and quality of colored fabric. Dyeing process is very common in textile industry and this process changes the physical and chemical property of fabric. There are various types of properties changes during knit cotton dyeing. It is very important that the changing property measurement. In this study I investigate the changing property such as WPI, CPI, Stitch Length, GSM, color fastness to Rubbing and color fastness to washing on cotton knit fabric that ensure to get the required product.For uniform dyeing, the fabric absorbency must be uniform. Here I investigated thus property of cotton knit fabric dyeing with reactive dyes. This paper tries to find out the major changes property of knit fabric from grey to finish. Hope this paper will help those people who are in textile dyeing industry.
