탄닌에 의한 견섬유의 증량 = Tannin Weighting of Silk Fiber

다국어 초록 (Multilingual Abstract)

The studies were performed to investigate the optimum condition for tannin processing of silk by use of Chiness Gallotannin and synthesized tannic acid, which was aimed at weighting.
1. It was found that the concentration of tannin solution for the efficient weighting of processed silk was 30gr/l of Chiness Gallotannin and 15gr/l of tannic acid. The optimum temperature and time for tannin treatment were 80℃, 60 minutes and the optimum acidity of tannin solution pH 2 to 3.
2. In dyeing the tannin treated silk by Acid Orange II , the dyeing temperature of 60℃ and dyeing time of 90 minutes were appropriate for the desorption control used for weighting of silk.
3. The colour differences of dyed silk fabric by soaping could be remarkably narrowed by tannin treatment, resulting in improving the washing fastness of tannin treated silk by two grade more than that of untreated one.
4. The light fastness of tannin treated silk could be drastically improved by reducing the dye - loss of dyed silk fabric which was coused from the ultraviolet irradiation.
5. The rubbing fastness and water repellency of tannin treated silk was at the same level with that of untreated one. However, the drape coefficiency of tannin treated silk was decreased more than that of untreated one, which is closely related with fabric softness and dressing appearence.
