당유자 과피 추출액을 이용한 직물의 천연염색

Abstract

This study examines the dyeability of fabrics in relation to dyeing temperature, time, concen tration, and the number of repeated dyeings. For this study, at first we extracted natural dyes from the peel of C. Dangyuza, which is fast as a dye and considered as recycling agricultural wastes. Additionally, it represents the image of Jeju Island. Then, we dyed cotton, wool, silk and nylon fabrics with the extracted dyes. The findings of this study are as follows.1) Dyed cotton, wool, silk and nylon fabrics with the extract of C. Dangyuza peel are gene rally yellow.2) Wool, nylon, silk, and cotton, in this order, are of good dyeability; Wool fabrics have the highest dyeability and cotton fabrics have the lowest. The dyeabilty of cotton fabrics was not improved even after dyeing in different conditions.3) Colorfastness with washing, rubbing and perspiration are all good, while colorfastness with light is poor.4) Higher dyeing concentration makes better dyeability.5) Dyeability is enhanced as the dyeing temperature increases, while the dyeability of silk and nylon is relatively good even at low temperatures.6) Looking at dyeability according to dyeing time, the longer the dyeing time, the better the dyeablility. Sixty minutes of dyeing time is appropriate to dye fabrics.7) With an increase in the number of repeated dyeings, increased dyeability is obtained.
