Problems solved by technology

The pupal lining has always been used as a tweezer, and its cotton sheets are mixed with a large number of pupa bodies, pupa shavings, molted skin and other impurities, and have a high oil content, so they can only be used as raw materials for silk spinning. The production cycle is long, occupies a large area, consumes a lot of water and soda ash, causes environmental pollution, and does more harm than good
[0003] Notification number CN1069532A, the date of the announcement is a Chinese invention patent on March 3, 1993, which announces a kind of production equipment and production process of pupa lining silk cotton. After dehydration, process methods such as transverse stretching and bulking to process the pupal lining into silk cotton, but the cotton sheet produced by this process method is not effective in removing impurities and oil, and the cotton sheet still contains many impurities and oil, and the cotton sheet is not soft enough 1. The color of the produced silk cotton is yellowish, the color is not white enough, the quality of the processed silk quilt is not high, and the cotton sheet is easily deformed during processing. Silk quilt, high cost, complicated operation, not suitable for industrial production

Embodiment 1

[0027] ⑴Feeding: Add the pupa lining into the pupa basin of the silk cotton machine;

[0028] (2) Alkaline water spraying: use NaOH solution with a mass concentration of 0.3% to spray on the pupal lining, and the temperature of the NaOH solution is 40°C;

[0029] (3) Rolling: Start the silk cotton machine, and the pupal lining after spraying with alkaline water is rolled into a primary cotton sheet with a thickness of 0.3cm and uniform thickness under the action of the silk cotton machine roller and blade;

[0030] (4) Cutting and soaking: Cut the primary cotton sheet from the drum, put each primary cotton sheet flat into a rectangular high-temperature-resistant shaping bag to form a shaped cotton sheet, and then soak it in clean water for 1 day, and the temperature of the clean water is room temperature;

[0031] ⑸Dehydration: Put the shaped cotton sheets soaked in step 4 into a dehydrator to dehydrate to a water content of 20%;

[0032] (6) Degreasing, degumming, and bleach...

Embodiment 2

[0039]⑴Feeding: Add the pupa lining into the pupa basin of the silk cotton machine;

[0040] (2) Alkaline water spraying: use 0.6% NaOH solution to spray on the pupal lining, the temperature of NaOH solution is 60°C;

[0041] (3) Rolling: Start the silk cotton machine, and the pupa lining after spraying with alkaline water is rolled into a primary cotton sheet with a thickness of 1cm and uniform thickness under the action of the silk cotton machine roller and blade;

[0042] (4) Cutting and soaking: Cut the primary cotton sheet from the drum, put each primary cotton sheet flat into a rectangular high-temperature-resistant shaping bag to form a shaped cotton sheet, and then soak it in clean water for 3 days, and the temperature of the clean water is room temperature;

Abstract

The invention discloses a process for processing a basin residue into a silk floss quilt. The process mainly comprises the steps of spraying with alkaline water, rolling, cutting, soaking, degreasing, degumming, bleaching, drying, beating, puffing and the like. By the process, the basin residue can be directly processed into the silk floss quilt; the process is simple, convenient and smooth in operation, low in production cost and suitable for industrialized production; and the produced silk floss quilt has uniform specification, little impurity and good grease removing effect, and is soft, pure white and high in quality.

Description

technical field [0001] The invention relates to the technical field of silk quilt production, in particular to a process for processing pupa lining into silk quilts. Background technique [0002] When the silkworm spins a lot of silk and the body shrinks greatly, the swing speed of the head and chest slows down, and there is no certain rhythm, and the silk spinning begins to appear messy, forming a loose and soft cocoon silk layer, which is called the pupal lining. In silk reeling, in order to ensure the quality of high-grade raw silk, measures are taken to remove the pupal lining in advance. The resulting cocoons are not fully utilized and become waste materials. The pupal lining has always been used as a tweezer, and its cotton sheets are mixed with a large number of pupa bodies, pupa shavings, molted skin and other impurities, and have a high oil content, so they can only be used as raw materials for silk spinning. The production cycle is long, it occupies a large area,...
