Abstract

Dyeable polypropylene fiber was woven and evaluated its dyeing characteristics and fastness using 22 commercial disperse dyes. Higher exhaustion yield was achieved at $130^{\circ}C$ compared to $120^{\circ}C$ dyeing where it ranged from 30% to 88%. The dyes contain diacetoxy or dinitrile group in the coupler ring and substituted by a nitro group in the diazotizer ring exhibited higher exhaustion yield. The calculated solubility parameter of suitable dyes for DPP fiber was in the range of 22.8-27.7. Color fastness, such as wash, rubbing, perspiration, light was revealed to be similar to those of PET dyeings.
