Research on application of composited auxiliaries in cocoon cooking process of practical reeling

Sulfonated castor oil and polyoxyethylene castor oil both have excellent surface activity, and they can be used as cocoon cooking additives. A new composited auxiliary was prepared based on the weight rate of polyoxyethylene castor oil：sulfonated castor oil：water with 1：25：15, which were used in the process of cocoon-cooking. The effect of the composited auxiliaries on silk reeling was studied, and the silk cohesion and silk strength was comparatively analyzed. The effect of composited auxiliaries on crystal structure of silk was studied by XRD and FT-IR. The results showed that, after adding the composited auxiliaries based on the traditional automatic silk reeling process, silk reeling results improved obviously, the average raw silk classification improved by 0.68 A, the cohesion testing times increased by 8.2, and the tensile strength of silk slightly improved. The raw silk crystal structure remained relatively constant, which was mainly 茁-sheet structure. It will be helpful for the application and popularization of the composited auxiliaries in the field of reeling.
