INFLUENCE OF THE LUMPY STRUCTURE OF THE COCOON SHELL ON THE TECHNOLOGICAL INDICATORS OF UNWINDING

Abstract

In the article, the influence of the sizes of tubercles on the wettability of the shell by layers is studied. The granular part of the cocoon shell is poorly wetted with water than the smooth inner part of the shell. But in cocoons of the Chinese hybrid, the wallpaper layers are almost the same. This is due to the height of the tubercles. Studies of the effect of cocoon grain size on unwinding performance are given. The results showed that the more tubercles per 1 cm2 of the shell area, the higher the unwinding and the yield of raw silk, respectively, at 122 and 38 tubercles, the unwinding was 80.53 and 69.65%, and the yield of raw silk was 42.3 and 32.9 %.
