生丝的草酸脱胶工艺研究
Research on degumming of raw silk with oxalic acid
摘要
Abstract
With oxalic acid as the degumming agent of raw silk ,the influences of oxalic acid con-centration ,reaction time ,bath ratio and reaction temperature on the degumming were investi-gated by single factor experiment .The optimal degumming conditions of silk degummed with oxalic acid are oxalic acid 4 g /L ,reaction time 40 min ,bath ratio 1 : 40 ,and reaction tempera-ture 100 ℃ .Silk was degummed with oxalic acid under the optimal conditions ,then reacted with 2 ,4 ,6-trinitrophenol-carmine solution .The results show that the degumming effect of ox-alic acid is the same as the degumming effect of sodium carbonate .The breaking strength and breaking elongation of silk degummed with oxalic acid are better than that of the control group . From the microphotographs , silk degummed with oxalic acid and the control group are slimmed .The surfaces of two degummed silks are sheen .But the cracks on the surface of silk degummed with oxalic acid are less than that of the control group .From infrared spectrum ,the structure of silk is not destroyed after degumming with oxalic acid .关键词
