The effect of the usage of fiber protecting agent and dye class on the damage of Angora fibers occurred during dyeing process

Abstract

Angora fiber's properties are affected adversely when dyed for prolonged periods at the boiling temperature, and to preserve its luster, one of the alternatives is to use a fiber protecting agents in dyeing. This study has focused on the use of fiber protecting agent to preserve Angora fiber during dyeing treatments carried out at boiling point. Furthermore the effect of dye class on fiber damage during dyeing was also determined. According to the experimental results, in dyeing process at 100 degrees C by adding fiber protecting agent into the liquor degree of fiber damage decreases and reaches to damage value of fiber dyed at 80 degrees C. Furthermore, it can be concluded that bifunctional reactive dye usage is advantageous for the aim of fiber protecting during dyeing.
