Embodiment 1

[0015] Take 100 kg of natural yellow silkworm cocoons, first pick out impurities, then infiltrate with 85°C, 0.75% sodium hydroxide solution for 8 minutes, and then spin and peel the cocoons at a temperature of 85°C and spray with a concentration of 0.75% sodium hydroxide solution, and then remove the silk and peel the cocoons The silk floss is washed with tap water and then dried and dehydrated with a dryer.

[0016] The dried silk floss is treated with 0.25% sodium peroxide and 0.3% hydrogen peroxide solution at a bath ratio of 1:25 at 100°C under normal pressure for 60 minutes, rinsed with clean water and then dehydrated for 3 minutes.

[0017] According to the bath ratio of 1:12, add 0.3% silk softener TF-404A, soak for 60 minutes at room temperature (above 10°C), adjust pH4 with glacial acetic acid After 8 days, it is dehydrated and dried to obtain yellow silk floss, which can be used to produce products such as natural light yellow mulberry silk quilts.

Embodiment 2

[0019] Take 100 kg of natural yellow silkworm cocoons, first pick out impurities, then infiltrate with 0.5% sodium hydroxide solution at 75°C for 10 minutes, then spin and peel the cocoons at a temperature of 75°C and spray with 0.5% sodium hydroxide solution, and then remove the silk and peel the cocoons The silk floss is washed with tap water and then dried and dehydrated with a dryer.

[0020] The dried silk floss is treated with 0.2% sodium peroxide and 0.2% hydrogen peroxide solution at a bath ratio of 1:20 at 90°C under normal pressure for 50 minutes, rinsed with clean water and dehydrated for 3 minutes.

[0021] According to the bath ratio of 1:12, add 0.2% silk softener TF-404A, soak for 60 minutes at room temperature (above 10°C), adjust pH4 with glacial acetic acid After 8 days, it is dehydrated and dried to obtain yellow silk floss, which can be used to produce products such as natural yellow mulberry silk quilts.

Embodiment 3

[0023] Take 100 kg of natural green silkworm cocoons, first pick out impurities, and then infiltrate them with 80°C, 0.5% sodium hydroxide solution for 5 minutes, spin and peel the cocoons at a temperature of 80°C, sprayed with a concentration of 0.5% sodium hydroxide solution, and then remove the silk and peel the cocoons The silk floss is washed with tap water and then dehydrated with a dryer.

[0024] The dried silk floss is treated with 0.2% sodium peroxide and 0.2% hydrogen peroxide solution at a bath ratio of 1:25 at 100°C under normal pressure for 50 minutes, rinsed with clean water and then dehydrated for 3 minutes.

[0025] According to the bath ratio of 1:12, add 0.3% silk softener TF-404A, soak for 60 minutes at room temperature (above 10°C), adjust pH4 with glacial acetic acid After 8 days, it is dehydrated and dried to obtain light green silk floss, which can be used to produce products such as natural green mulberry silk quilts.

Abstract

The invention discloses a production method of natural colorful mulberry silk floss. The traditional common technology is difficult to reserve the natural color of the colorful cocoons, and the color is faded into white in the processing process. The production method disclosed by the invention comprises the following steps of: selecting cocoons and removing impurities from colorful cocoons; permeating with alkaline water; reeling silk from cocoons to remove the pupa; cleaning and dewatering; adding a degumming agent to keep color and refining; removing gum and grease; decontaminating, rinsing and dewatering; adding a spun silk softening agent; regulating the pH value to 4-8; and dewatering and drying to obtain the silk floss. The method has the advantage of simple technology, and the produced silk floss has the advantages of colorful appearance, even color and luster, low trash content, soft mouthfeel, good tearing toughness and no peculiar smell and can achieve the standard of producing high-quality mulberry silk floss quilts.

Description

technical field [0001] The invention belongs to the technical field of home textiles, and in particular relates to the production of natural colored cocoon mulberry silk floss and a processing method of mulberry silk floss keeping the natural color of silk. Background technique [0002] Our country is rich in resources of natural colored cocoon silkworm varieties. With the advancement of science and technology, natural colored cocoon silkworm varieties have been bred, such as golden yellow silkworm cocoon varieties, green silkworm cocoon varieties, etc., and are being developed and applied. The production, use and wearing of natural colored cocoon silk clothing has also become fashionable, and it is a symbol of today's low-carbon environmental protection concept. [0003] Existing studies have shown that the intermolecular porosity of silk protein in natural yellow cocoon silk is 37% to 53% larger than that of conventional white cocoon silk in production. It is speculated th...
