· Singeing is the first step of pre-treatment. The process by which loose, hairy, and projecting fibers are removed is called Singeing. Desizing Desizing is the second step of pre-treatment. Through this process, gummy materials are removed. Also, size materials are removed by this process. Scouring Scouring is the third step of pre-treatment.

 · Basically, the dyeing process is all about absorption and diffusion. Absorption is transferring of dyes from the aqueous solution onto the fabric surface and diffusion is dyes getting diffused into the fibers. Of course, the temperature and other controlling factors play a major role. This dyeing can be either done by hand or machine.

 · Yarn dyeing is carried out by either one of the following three dyeing methods: 1) Skein dyeing, 2) Package dyeing and 3) Space dyeing. Among these, package dyeing is the most common yarn dyeing process. Skein dyeing is performed by suspending skeins of yarn in an agitated dye bath with possible additional movement of the skeins during dyeing.

Waterless Technologies for Sustainable Dyeing. The dyeing process of textiles varies depending on the type of fabric. Cotton dyeing is a longer and more water and heat-intensive process, due to the negative surface of cotton fibers. This means that usually cotton only takes up about 75% of the dye that is used. In order to make sure color holds ...

Crocking. Crocking defect occurs in the fabric when the color of the dyed fabric rubs off onto other fabrics easily. The causes for this type of defect can be as follows -. The scouring done at the end of the dyeing process was not done properly. There was insufficient penetration of the dye in the fabric.

 · Citric acid is found to be one of the most effective cross-linking agents for crease resistant finish. High concentration of citric acid and Trisodiumcitrate shows excellent crease resistance, where whiteness index became reduced at higher concentration of citric acid. The optimum curing temperature of 160°C gives best crease recovery angle.
