Different ingredients of the fabric, the application of dyes and dyeing methods are not the same, such as cotton fabric for sulphur dyes, reactive dyes, vat dyes, etc., and polyester fabrics for disperse dyes, and hair fabrics and more use of acid dyes.
Different kinds of fabrics are suitable for different dyes and dyeing methods, such as denim dyes commonly used in denim, indigo dyes, etc., but not suitable for reactive dyes. Medical uniforms use Shihlin dyes, not suitable for sulphur dyes.
The same fabric, different dyes coloring, fabric style and performance will also be very different. The color of cotton vulcanized black fabric is enough, but easy to brittle, strength reduction, low color fastness. Cotton active black fabric blackness is not enough, but the friction color fastness is good, no brittle phenomenon.
Therefore, it is of great significance to understand the properties and characteristics of various dyes and to select the appropriate dye dye according to the composition, style and use of the fabric.
