Abstract:
A method of deepening the color of fibers comprising applying from 0.1 to 8 weight percent of a water-based fiber treatment agent to the fibers, based on the weight of the fibers, (i) the fibers being selected from the group consisting of regenerated fibers, semi-synthetic fibers, synthetic fibers, raw yarn, mixed yarns, raw cotton, cotton wadding, fabrics, tows, knits, or weaves, (ii) the water-based fiber treatment agent containing (A) about 100 weight parts of a silicone oil, (B) about 5-200 weight parts of a silicone rubber powder having an average particle size of 0.1-500 &mgr;m, and (C) water, and (iii) the silicone rubber powder (B) being an aqueous dispersion of silicone rubber powder produced by addition curing, condensation curing, organoperoxide curing, or ultra-violet light curing of a silicone rubber composition while the silicone rubber composition is emulsified in water using an emulsifying agent.
