Pattern Making In garments making; different types of modern equipment are added to ensure the quality of the products. Day by day; man wants to design their pattern by the modern system. For this man introduced CAD and Digitizing system for making the pattern design. This system also decreases the rate of defects in garments. … Read more
Warping In textile language; warping is defined as the parallel winding of yarn from a cone or cheese package onto a warp beam. It is needed to confirm that the warp beam is made from good warp yarn otherwise weaving performance will be hampered. So it needs to require to provide a good warp beam. … Read more
Direct Dyes Direct dyes are sodium salts 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 at at low temperatures. After absorbing dyes it tends to bleed the dyes, which produces an uneven 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
Basic Dyes Basic dyes and their application in the dyeing and printing processes are interesting. Jute fiber and its generated products are treated with basic dyes. I have written about jute fabric printing with basic dyes in one of my blog posts. I think that’s will help you to know about the printing process of … Read more
Sulphur Dye Sulphur dyes are one of the most commonly used dyes for producing bright black and brown shades on cellulosic fiber products. The chemistry of sulphur dyes dyeing is similar to that of vat dyes dyeing. In both cases, the final colour is developed by the oxidation process. Although, reactive dyes, azoic colour is … Read more
