Problems solved by technology

Due to the limitation of technology development, the production of colored cocoons is still carried out through the traditional silk cotton processing technology, which brings defects such as poor color retention and easy fading of the product. At the same time, in the processing technology, high-concentration caustic soda is used. Reduce the pressure of wastewater treatment, and reduce the flexibility of the product to a large extent

Embodiment 1

[0032] The production process of colored cocoon silk cotton, the steps are as follows:

[0033] ①, vacuum infiltration

[0034] Pour the colored cocoons into a vacuum tank (total volume 0.6 cubic meters, effective use area 0.45 cubic meters) and lay it flat, put the cocoon pressing board, cover the tank lid, and close the water inlet valve, drain valve and steam inlet valve. Turn on the motor, open the vacuum valve, and pump out the air in the tank.

[0035] When the vacuum degree reaches -0.098Mpa, open the water inlet valve, and close the water inlet valve after the water level exceeds the cocoon pressing plate by 5-7cm. Open the steam inlet valve, and use the pressure difference to press water into the cocoon cavity (cocoon cavity).

[0036] After the vacuum degree returns to "0", close the steam inlet valve, and the vacuum penetration is completed.

[0037] Open the tank cover and the cocoon pressing plate, open the drain valve to release water, when the water level is ...

Embodiment 2

[0057] The concentration of the soda ash solution A injected in the cotton making machine in the step 3. is 0.58%, the concentration of the soda ash solution B that the degumming and degreasing process adopts is 0.48%, and the soft and fluffy treatment is prepared by glacial acetic acid: softener: water is 0.1: 6.2: 990 Solution C, others are the same as in Example 1.

Embodiment 3

[0059] The concentration of the soda ash solution A injected in the cotton making machine in step 3. is 0.63%, the concentration of the soda ash solution B that the degumming and degreasing treatment adopts is 0.51%, and the soft and fluffy treatment is prepared by glacial acetic acid: softener: water is 0.1: 6.25: 980 Solution C, others are the same as in Example 1.

Abstract

The invention discloses a production technique for colorful cocoon silk cotton. The production technique is characterized by comprising the procedures of vacuum infiltration, cocoon cooking, silk cotton production and the like; the degumming and degreasing treatment adopts solution prepared by a ratio of (4.8-5): (980-1020); and the softening and fluffing treatment adopts solution prepared by a ratio of 0.1: (6.1-6.3): (980-1020) amongglacial acetic acid, softening agent and water. The production technique for the colorful cocoon silk cotton, disclosed by the invention, finally prepares the colorful silk cotton products through the innovated procedures of vacuum infiltration, cocoon cooling and silk cotton production; and the soft degree and the fluff degree are largely improved. And at the same time, the color retention of the products is higher, and the products are difficultly faded. Soda ash beneficial to the environment is adopted to replace caustic soda in the traditional technique, so that the waste water treatment pressure is relieved, and the products show the incomparable advantages of the traditional technique in the aspects, such as color and appearance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production process of colored cocoon silk cotton. Background technique [0002] At present, silk quilts, pillows and other products manufactured by dyeing process are easy to fade when used, and long-term use will cause certain harm to human health. [0003] With the development of silkworm breeding industry, colored cocoons are gradually being widely promoted. Products such as silk quilts and pillows produced by using colored cocoons have gradually attracted widespread attention. Due to technical development limitations, the production of colored cocoons is still carried out through the traditional silk cotton processing technology, which brings defects such as poor color retention and easy fading of the product. At the same time, in the processing technology, high-concentration caustic soda is used. The pressure of wastewater treatment is reduced, and the flexibility of th...
