Generally, compounds formed as a result of acid and base reactions are called salts. Salts have a wide range of uses.
A significant amount of salt is consumed in the dyeing of cellulose, protein and synthetic based fibers with different dyestuff groups in different processes of textile finishing and textile dyeing. In textile dyeing, especially when dyeing cotton fabrics with reactive dyestuffs, a lot of salt is added to the liquor. According to the extraction method with reactive dyestuffs, approximately 10-100 g/l salt is used depending on the substantiveness of the dyestuff, dyeing darkness and liquor ratio. If we give an example from other dyestuff groups, working with direct dyestuffs is about 10-30 g/l depending on the light and dark of the color, 5-25 g/l according to cold and warm dyeing methods (IK and IW type dyestuff) for cube dyestuffs, 5-20 g/l for sulfur dyestuffs. In acid, chromium, 1:1 metal complex dyestuffs used for dyeing g/l, wool and PA fibers, about 5-10 g/l salt is used depending on whether the color is light or dark. In addition, for dyeing PAC fibers with basic dyestuffs, it is recommended to use 5-10 g/l salt in some dyeing methods. Apart from dyeing made by shrinkage method, salt is also used in some dyeings made by impregnation method and in wet fixation of prints. Therefore, salt has an important function in textile dyeing.
It is used in dyeing processes in the textile industry.
+ Increases color efficiency.
+ Prevents abrasion caused by not melting salt properly.
+ Increases the repeatability (RPT) values of colors due to being standard.
+ Eliminates the labor and cost required to dissolve salt.
+ Since it is completely clean and free of impurities, it prevents the average 6% collapse loss.
+ Saves energy costs as it is offered as liquid.
