Problems solved by technology

However, silk floss on the market is mostly produced through traditional cooking, hand peeling, stretching, scouring and other steps. Basically, it feels hard, has many scars, yellow color, dark luster, heavy pupa oily smell, poor softness, and is not fluffy. , Easy to harden, its production process is long, time-consuming, high energy consumption, low economic benefits

Embodiment 1

[0033] Take 37.5kg of Shuanggong cocoon and divide it into 150 bags, add 750kg of water to the cocoon cooking pot, and add 2.25kg of Na when the water temperature reaches above 98°C 2 CO 3 , 2.5㎏H 2 o 2 ,, 600 g Na 2 SiO 3 , Stir evenly, put it into the cocoon bag, cook at 97°C for 30 minutes, then cook at 92°C for 20 minutes, and turn it every 10-15 minutes during the cocoon cooking.

[0034] Rinse the pot with clean water. After there is no sewage, open the sponge for dehydration. The specific process is to stretch the boiled cocoon on the left palm by the worker with a fixed small stretching technique. During the process, impurities such as silkworm chrysalis and peeling must be removed. After rinsing with water, a small cotton sheet is completed for every 6-8 cocoons, and then 8-12 small cotton sheets are evenly stretched on an oval-shaped bamboo stretch by a large stretcher to complete a large bag of cotton and dehydrated.

Abstract

The invention provides a method for producing silk floss from double cocoons, which is characterized in that: (1) cocoon selection and subpackaging; (2) cocoon cooking; the cocoon cooking solution is composed of water, Na2CO3, H2O2, Na2SiO3, and its liquor ratio is 1 : 20; (3) clean; (4) open cotton, make small cotton sheet, then make small cotton sheet into bag cotton, dehydration; (5) post-processing; bag cotton is placed in softening liquid for soaking treatment, The softening solution is composed of water, silk cotton softener A and silk cotton softener B, and the bath ratio is 1:15-18; (6) dehydration and drying to obtain silk cotton. Fluffy, white and high-quality silk floss can be obtained through the above method, and the pollution to the environment can be reduced in the production process.

Description

technical field [0001] The invention relates to a method for processing biute cocoons into high-quality silk floss. Background technique [0002] Silk is a kind of animal protein fiber, it contains 18 kinds of amino acids, (including 8 kinds of amino acids necessary for the human body), can promote metabolism, improve sleep quality, has the reputation of "second skin" of the human body, silk made of silk The quilt is fluffy, soft and close-fitting, with strong warmth retention, and can automatically adjust the temperature and humidity inside the quilt, making people feel more comfortable. Silk floss can also be used as fillers for clothes, pillows, insoles, etc., and its uses are quite extensive. [0003] Shuanggong cocoon refers to a silkworm cocoon made by two or more silkworm babies. Its shape is larger than that of a single silkworm. Because it is intertwined when spinning, the cocoon silk is messy and thick and cannot be reeled into genuine silk. It is the best raw ma...
