Dyeing of silk with Procion HE dyes

摘要

The effect of various dyeing parameters on exhaustion and fixation of bifunctional monochloro-triazine dyes (Procion HE dyes) on silk has been studied. Factorial design has been used to obtain the optimum conditions of dyeing. Maximum exhaustion has been obtained with 110 g/L sodium chloride and 3 g/L sodium carbonate. Temperature in the range 60-80℃ has no influence on exhaustion. Improvement in mechanical properties of dyed silk suggests the formation of crosslinks in the fibre by these dyes.
