Softening Agents Softening agents are one of the finishing agents which give softness, better handle, drape, cutting, and sewing qualities to the fabric. It is applied on the fiber, yarn, woven or knitted fabrics during the dyeing process. Softening agents are applied to the materials at the last stage of the dyeing process. Most of … Read more
Direct Dyes Direct dyes are sodium salt of sulphonic acid and most of them contain an azo group as the main chromophore. Additionally, direct dye dyeing is carried out in alkaline conditions. This dyeing process is done comparatively at low temperatures. After absorbing dyes it tends to bleed of dyes which produce unevenness of shade, … Read more
Vat Dye Vat dyes are different from reactive dyes, disperse dyes, basic dyes, acid dyes, or azoic color but their application process is near similar to sulphur dyes. Vat dyes are used for coloring cellulosic fiber especially cotton fiber. It is widely used for running the dyeing process of cotton yarns which is used for … Read more
