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.
Phenylglycidyl ether 處理 絹纖維의 Gas Chromatography-Mass Spectrometry
南成祐 成均館大學校 科學技術硏究所 1992 論文集 Vol.42 No.2
Gas chromatography and Mass spectrometry of the hydrolysate of phenylglycidyl ether treated silk were studied. The GC and GC-MS analysis were carried out by the linear temperature-programmed method on OV-17 column, after the amino acids in the hydrolysate being convertied to n-butyl esters of N-trifluoroacetyl(BTFA) derivatives. The peaks of O-(2-hydroxy-3-phenoxypropyl) tyrosine and 2, 3-dihydroxypropylphenyl ether were observed in the gas chromatogram and mass spectrometry of the PGE treated silk.
