REAL-TIME STUDY OF COCOONS OF SILKWORM SHADE

In order to produce high-grade raw silk, it is necessary to sort the cocoons according to the shade of the shell color. Visually, the white cocoon shells of the Mayin Tola-1 and Mayin Tola-2 hybrids turned out to be about 67.9-46.2% purple, 2.06-15.4% yellow, 23.0-30.2% cream and 6.5-7.5% yellow-brown shades, respectively, under ultraviolet irradiation. Cocoons with a purple shade of the shell had the highest technological indicators. With the help of dyeing, it is shown that silk produced from raw materials of the same shade, established with the help of ultraviolet transmission, received a uniform color, and the control, consisting of raw materials of various shades, was dyed with a defect, unevenly. It has been established that for the production of smooth-dyed silk fabrics of delicate tones, it is necessary to use raw silk as a raw material, produced from cocoons with the same shade of shell color.
