정향 추출물을 이용한 염색직물의 염색성 및 기능성

Abstract

This study was accomplished to examine the dyeing property and functionality of both cotton and silk fabrics dyed with clove extract. The purpose of this study was to investigate the effects of dyeing property, antibiosis, and sun protection effectiveness for a clove. The study method used in this study was the experimental research to extract dyestuffs from a clove, to treat dyestuffs with a mordant, and then to measure dyeing colorfastness, antibiosis, and sun protection for dyed fabrics. As a result of the test for dyeing colorfastness, in the case of colorfastness to laundry, the degree of discoloration showed grade 1～4 and the degree of pollution showed grade 4～5. Colorfastness to perspiration for both cotton and silk fabrics dyed showed grade 1～2 to 4～5. Colorfastness to sunlight showed grade 2 to 4～5. Colorfastness to rubbing showed grade 3～4 to 4～5. In the colorfastness to dry cleaning, the degree of discoloration showed grade 3～4 and the degree of pollution showed grade 4～5. As a result of the antibiosis test, for the Staphylococcus aureus, both cotton and silk showed the bacteria reduction rate of 99.9% even after five times laundry, and for the Escherichia coli, cotton fabrics showed the bacteria reduction rate of 99.9% only after one time laundry, but silk fabrics showed the bacteria reduction rate of 99.9% even after five times laundry. As a result of the test for sun protection effectiveness, dyed silk fabrics showed the result more excellent than dyed cotton fabrics.
