摘　　要：从触蒸过程中丝胶微观结构变化和茧层结构变化着手,探讨触蒸前处理提高生丝洁净成绩等的机理。认为丝胶在触蒸过程中既发生变性又发生变质。就一般干茧触蒸,在较高的触蒸温度下,丝胶溶解性提高。触蒸可增加丝层之间的胶着抵抗,这在茧层结构比较疏松的茧子中显得比较明显。本文还分析了触蒸前处理对缫丝成绩和生丝品质的影响,指出真空触蒸工艺比常规触蒸工艺触蒸均匀。Through investigations of the changes in sericin microstructure and shell structure of cocoonssubjected to direct steaming, the mechanism of the process for improving raw silk neatness isstudied. It is believed that the denaturation and deterioration of sericin will occur in directsteaming, causing higher dissolvability of sericin of dried cocoons at a higher temperature.Morever, direct steaming will reduce the adhesion between cocoon layers, especially for loose-shellcocoons. The article also points out that vacuum direct steaming, in comparison with theconventional one, can obtain more evenly-cooked cocoons, resulting in better raw silk.
