Problems solved by technology

The processing method described in Chinese patent 91111324.X, although a small amount of cocoon clothing is used to fix the cocoon clothing in the blended fabric, does not fully utilize the cocoon clothing and does not change the performance of the cocoon clothing silk; while the Chinese patent 91111324.X Although the processing method fully utilizes the properties of the cocoon, and makes the sericin in the cocoon silk easily denatured by the aldehyde group to make high-elastic silk, it does not solve the problem that the sericin is still degummed and hardened after being boiled in a weak acid or weak alkali solution. question
In addition, due to the denaturation of the dialdehyde-based solution used in this method, the solution contains a large amount of formaldehyde, which does not meet the national standard requirements for formaldehyde content. Therefore, the silk produced by this method can only be used as fillers that are not close to the body. extremely limited range

Embodiment 1

[0017] Screen the cocoon coat to remove impurities, weigh 500 grams of the cocoon coat, and put the cocoon coat in the mixing tank to soak for 1 hour. The pH of the solution in the tank is 2, and the acid solution weighs 5 kg. Turn it every 0.5 hours, and use a dehydrator for dehydration after soaking; put the dehydrated cocoon into a glutaraldehyde solution for 6 hours, the pH of the solution is 2, and then put it in the dehydrator for dehydration after soaking; Put the dehydrated cocoon into an alkaline solution with PH=10 and soak for 14 hours. Heat the alkaline solution to 60°C, turn it over every 1 hour, and then dehydrate after soaking; put the dehydrated cocoon into the last Soak it in an alkaline solution containing water glass with pH=10 for 18 hours, wash and dehydrate the last soaked cocoon, and dry it at a temperature lower than 100°C to obtain 450 g of silk spun refined dry product.

Embodiment 2

[0019] Screen the cocoon coat to remove impurities, weigh out 1000 grams of cocoon coat, put the cocoon coat into a pH=3 acid solution bath and soak for 3 hours, turn it over every 1 hour, and dehydrate after soaking; dehydrate the cocoon after soaking Put the clothes into a solution containing glutaraldehyde and soak for 10 hours. The pH of this solution is 4, and then undergo dehydration treatment; put the dehydrated cocoon clothes into an alkaline solution with PH=12 and soak for 18 hours. The solution was heated to 80°C, turned once every 1 hour, and dehydrated after soaking; the dehydrated cocoon was finally put into an alkaline solution containing water glass with PH=12 and soaked for 24 hours. The last soaked cocoon clothes are washed, dehydrated, and dried at a temperature lower than 100° C. to obtain 950 g of spun spun refined product.

Abstract

A technology method for softening solid sots baves to manufacture schappe spinning fine products includes the following steps: Selecting cocoons - swelling - protected by sols-solid sols softened - protection sols softened - cleaning and washing - drying, finally silk spun fine products are got.

Description

Technical field [0001] The invention belongs to the silk spinning industry, and particularly relates to a process method for preparing spun spun refined products by softening solid rubber and using cocoon garments as raw materials. Background technique [0002] Cocoon silk is the chaotic part of the outer layer of the cocoon, which accounts for about 5% to 7% of the cocoon. It is characterized by short and messy fibers and high sericin content. It melts in water and becomes a hard lump after drying, and has a peculiar smell. Therefore, it is rarely used in actual production, and only a small amount of cocoon yarn can be spun into cotton or wool blend. In order to turn waste into treasure and make rational use of cocoon clothing silk, Chinese patent 91111324.X discloses a processing technology of cocoon clothing silk staple fiber, and Chinese patent 95111290.2 discloses a process method for denaturing cocoon clothing silk to produce high-elastic silk . The p...
