摘要
针对天然彩色蚕丝纤维精练过程中色素随丝胶的去除而流失的问题,以保留天然彩色蚕丝纤维中色素和颜色特征值为目标,采用生丝接枝、交联和汽蒸的方法,探讨不同工艺及条件对天然彩色蚕丝相对增重率和颜色特征值的影响。结果表明,先接枝后交联的同浴工艺对提高纤维相对增重率和表观色深度是有利的,其中以柠檬酸为酸介质,丝纤维颜色特征值的变化较小。预汽蒸后,先交联后接枝工艺整体优于先接枝后交联工艺。与未处理的丝纤维相比,处理后丝纤维的饱和度降低,色调偏向绿光。
For the problem of naturally colored silk′s pigment lost with the removal of sericin during scouring seriously,this paper aimed at preserving the pigment of naturally colored silk and color feature,and investigated the effects of different processes and process conditions on the relative weighting percentage and color feature through such methods as grafting,cross-linking and steaming.The experimental results indicated that： it is favorable for increasing the relative weighting percentage and apparent color depth by one-bath process of first grafting then cross-linking.In this method,when citric acid was used as acid medium,the change of color feature was insignificant.After pre-streaming,the process of first grafting then cross-linking is obviously better than the technology of first cross-linking then grafting.Compared with the untreated silk fiber,the saturation of processed fiber was lowered,and the color tone trended to green.
