[0002] see figure 1 In the silk degumming in the prior art, except that the temperature of the enzymatic refining process is controlled at about 40°C, other prepreg, primary refining, and re-strengthening processes must be carried out at a high temperature of 90-98°C, so that it is possible to degumming the silk. Sericin is removed cleanly

Embodiment 1

[0014] 30-60 g / m² natural colored silk. The concentration of the degumming solution is 15g / l sodium hydroxide, 5g / l sodium tetraborate, and 15g / l Remibond A. After soaking or padding the silk fabric, put it in cold storage at 20°C for 24 hours, and then wash it with water. Auxiliaries and hydrolyzed sericin on silk fabrics are washed and finally dried.

Embodiment 2

[0016] 30-60 g / m² natural colored silk. The concentration of the degumming solution is potassium hydroxide 15g / l, sodium tetraborate 5g / l, and Remibond A 15g / l. After soaking or padding the silk fabric, put it in a cold stack at 30°C for 16 hours, then wash it with water, and absorb it on Auxiliaries and hydrolyzed sericin on silk fabrics are washed and finally dried.

Embodiment 3

[0018] 30-60 g / m² natural colored silk. The concentration of the degumming solution is sodium hydroxide 15g / l, sodium tetraborate 5g / l, and Remibang A 15g / l. After soaking or padding the silk fabric, put it in cold storage at 40°C for 10 hours, and then wash it with water. Auxiliaries and hydrolyzed sericin on silk fabrics are washed and finally dried.

Abstract

The invention relates to a method for degumming natural color silk. The method comprises the steps of preparing degumming solution, dipping or padding, cold stacking, water washing and drying, wherein the proportion of the degumming solution is as follows: strong base with pH value of inorganic over 12 accounts for 1.5 to 3 percent of total weight of the degumming solution; sodium tetraborate accounts for 0.5 to 1.5 percent of the total weight of the degumming solution; Lamepon A accounts for 1.5 to 3 percent of the total weight of the degumming solution; and water accounts for 97.5 to 92.5 percent of the total weight of the degumming solution; the Lamepon A is an anionic surfactant, and is a condensation compound of oleoyl chloride and protein hydrolysate. The invention provides the technology which not only ensures that sericin can be removed from the natural color silk completely, but also ensures that the color of the natural color silk cannot be removed. The method has the advantages: 1, sufficiently degumming the natural color silk, and maintaining the original color of the natural color silk; 2, saving energy by adopting cold stacking in the degumming process; and 3, never heating or seldom heating to reduce the temperature of a workshop and improving working environment.

Description

Technical field: [0001] The invention relates to a method for degumming natural colored silk. Background technique: [0002] see figure 1 In the silk degumming in the prior art, except that the temperature of the enzymatic refining process is controlled at about 40°C, other prepreg, primary refining, and re-strengthening processes must be carried out at a high temperature of 90-98°C, so that it is possible to degumming the silk. Sericin is removed cleanly. However, if this process is used to degumming the natural colored silk, it will remove the sericin of the natural colored silk and at the same time remove the natural pigment in the natural colored silk, and lose the color of the natural colored silk, making the high-grade Natural colored silk becomes plain white silk. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a kind of natural color silk that...
