Dyeing process in textile-100% applied process for knit fabric

dyeing process in textile

Dyeing is a process of coloring the textile fiber. Dyeing process in textile depends on some factors-

  • Fiber type
  • Fabric type
  • Dyes behavior
  • Machine condition
  • Raw materials
  • Shade %

Some dyeing process in textile industry are discussing bellw. These process is so efective for factory level. All the process are 100% applied process. So that every one can use this process to get better productin and better quality fabric.

100% cotton fabric Dyeing process in textile

Cotton is a cellulosic fiber. So that dyeing process will be reactive dyeing process. Because reactive dyeing process is widely used in textile industry. A dyeing process is given below:

100% Viscose fabric dyeing porcess:

Viscose is a regenerated cellulose fiber. So that we use here reactive dyeing process. The absorbency of viscose fabrc is so higher. Strength is also lower than other collon fabrc. So dyin process of this favric is so sencitive.

Lubricant + oil remover= sequestering agent= Inject

Temp 40c*= Fabric Load
