Abstract

The invention can be used in silk-woking industry in the processing of coconut waste. The purpose of the invention is the superior qualities of silk fiber. For this, in the method of obtaining silk mass from coconut-waste, including drying odonok, clearing free yarn, cutting shells, removing the pupal and aging the shells in an acidic environment, the shells of odonok before boiling them are boiled in portions at a temperature of 90-95 ° C and pH II - 12 for 10-15 minutes 2 tab. co 00 co co

Description

SUBSTANCE: invention relates to silk industry, can be used on silk-weaving enterprises for processing coconut waste and is additional to the main one by auth. M 1245625,

The aim of the invention is to improve the quality of the silk mass obtained from odonok and cocoon failure due to the reduction of fatty substances.

This goal is achieved by the fact that according to the method of obtaining silk mass from coconut-waste, which includes drying, cutting shells, removing the pupa and keeping the shells in an acidic environment, the shells are aged before boiling in portions at 90-95 ° C and pH 11-12 for 10-15 min.

The method is carried out as follows.

Arriving from the coconutary shop of the odonki and cocoon unwort is squeezed in a centrifuge and dried, for example, in a conveyor dryer according to the mode of decreasing temperature at a temperature equivalent of 25-10 and dried to 7-8% residual moisture. Dried odonki clear of svog

bodysupply rollers. The cleaned shells of the odonok are cut and separated from the pupa.

Next, the odonok shells are boiled in small portions for 1015 minutes at a pH of 11-12 and a temperature of 90-95 ° C. Then, according to a known method, odonok shells are kept in an acidic medium with a pH of 3.0-3.5 at 55-60 s for 20-25 minutes.

The resulting silk-like mass is washed, dried, loosened and processed according to a known method. The information on the effect of the processing conditions for odonks on the properties of the obtained canvas is given in Table. one .

The tabl data indicate that the proposed method provides obtaining silk mass of the best quality at pH 11-12 and temperatures of 90-95 ° C for 10-15 minutes. With these cooking parameters, the optimal amount of sericin is achieved, which ensures the necessary strength of the fiber and the minimum amount of grease and clogging of the fiber.

Example Odon and non-stocked cocoons coming from the coconutary shop are squeezed out on a centrifuge and dried by a convection method on a band saw to a residual moisture content of 8%. Drying is carried out in a mode of decreasing temperature from 110

up to 60 ° C for 50 minutes at a temperature equivalent of 25-10 "

The dried blend of odonok and non-stocked cocoons is treated on a CA-70 peeling unit to remove free filaments. Next, the odonki are cut and separated from the pupa on ICA coconut-cutting units.

The cut shells of odonok are packed in bags in portions of 200-250 each.

g and boil in the apparatus PLASH-1 at 93 C, wring out, washed. Then odonki kept in an acidic environment at pH 3.0 and a temperature of 58 ° C for 22 minutes The resulting blend mass is treated and prepared for spinning according to a known method.
