Abstract

Deep coloration of cotton fabrics with concentrated Rhus verniciflua extract was carried out using large amount of Glauber's salt and a mordant in order to improve dyeability and functional properties such as deodorizing and antimicrobial activity. With increasing in the salt addition upto 80% in the dyeing liquor containing 0.45% extract concentration, K/S value and exhaustion increased threefold from 1.2 to 3.5, indicating that the salt reduced the electrostatic repulsion between the dyes and the cotton fibers. Also the concentrated extract solution to 8% can increase the color build up upto a K/S of 11.1. In addition the combined pre- and post-mordanting methods with potassium alum enhanced the dyeability upto a K/S of 22.2. The ammonia deodorizing property increased with increased color yield of the dyed fabrics. Also the dyed and post-mordanted fabrics with 8% extract concentration showed antimicrobial activity against both Klebsiella pneumoniae and Staphylococcus aureus.
