견직물에 대한 유채의 염색성 및 항균성

Abstract

This study was investigated to establish the optimum conditions of dyeing silk fabric with Brassica campestris.This experiment was done under different dyeing conditions of dye concentration, dyeing temperature, dyeing time, dye-mordanting were evaluated in terms of dyeaffinity(K/S value) and CIE-Lab color factors. Also, the effect of mordantingon color fastnesses was assessed. The dyeaffinity increased remarkably as dye concentration increased up to 200% owf.The dyeaffinity increased continuously with dyed temperature and reached dyeing equilibrium at 80oC. The maximumdyeaffinity was observed at 30minutes of dyeing time. In the relationship between the K/S value and dyeing repeatingtimes, the K/S value became higher as repeating time was increased. The changes of surface color and colorfatness ofdyes were not increased greatly on all mordanting states. The extracts of Brassica campestris produced mainly yellowcolor in silk fabric. The antimicrobial activity existed slightly as the ratio of 22.7%.
