A Study on the Evaluation of Functional for Naturally Dyed Using the Liquid Extracted from Lacquer

This paper was carried out to investigate the fastness to washing, perspiration, rubbing and light of the hemp, ramie, and silk fabrics dyed with naturally dyed using the liquid extracted from Lacquer. Three kinds of natural plant colorant extract solutions were obtained by extraction from sappan wood, barberry root and polygonum indigo using water at 90℃ for 90 min with a liquer ratio of 1:10. The fastness to washing and perspiration in the three fabrics dyed with mixed dyeing improved in 4～5 grade. But the fastness to rubbing in a dry-type and light of the silk fabric improved in 3～5 grade. The bacteria reduction rate of the hemp and ramie fabrics increased at 98.2～99.1% by mixing naturally dyed using the liquid extracted from Lacquer without heavy metal contents. In view of the results, it obtained visible achivements for fastness and Antimicrobial property and environmentally friendly fabrics through the mixed dyeing with naturally dyed using the liquid extracted from Lacquer.
