Problems solved by technology

[0003] Silk is smooth, breathable, soft, moisture-absorbing, non-itchy, and anti-static, making it an excellent material for making skin-friendly products; and because silk is attached to the surface of sericin, it will slightly dissolve when exposed to moisture at temperatures above 38°C; Sericin is an extremely nutritious substance that will accelerate the growth of bacteria. Therefore, when used as a medical material that is close to the skin, it may accelerate the reproduction of bacteria, which is not conducive to wound healing, and may further cause skin infections

Embodiment example 1

[0023] Implementation Case 1: A Manufacturing Process of Silk Staple Fiber

[0024] A kind of manufacture craft of silk short fiber, wherein: described manufacture craft step is as follows:

[0025] 1) Cocoon opening: open the cocoon, the opening is not larger than one-third of the cocoon;

[0026] 2) Cocoon selection: Remove the silkworm chrysalis, choose the cocoon without silkworm excrement on the inner wall, discard the silkworm cocoon with silkworm excrement on the inner wall; avoid the silkworm chrysalis and excrement from polluting the purity of the extracted sericin;

[0027] 3) Cocoon washing: Wash the selected cocoons with clean water to remove pollutants, such as dust in transportation, pollutants in the atmosphere, and pollutants from hands when cocoons are opened and selected by hand, and dried for later use. Drying can be done manually or by hand. drying machine;

[0028] 4) Degumming for the first time: Put the spare cocoon into the high-temperature still, set...

[0035] Implementation Case 2: Clothes Woven Using Silk Staple Fiber

[0036] Step 1: Reference implementation case 1 for the method of obtaining short silk fibers;

[0037] Step 2: Weave silk yarn from short silk fibers using modern spinning technology;

[0038] Step 3: Weave the woven yarn into cloth by traditional methods, and cut it into clothes.

[0039] Clothes cut using the short silk fiber as raw material have the advantages of good warmth retention, no bacteria breeding, no sticking to the skin, close fitting and not easy to wrinkle, etc.

[0040] Implementation Case 3: Sanitary napkins woven with short silk fibers

[0041] Using the non-woven fabric water weaving process, the silk staple fiber is woven into a non-woven fabric. This kind of non-woven fabric can be used to make high-end mask paper, and can be used to make band-aid inner cloth, feminine hygiene cloth inner cloth, etc. This kind of sanitary cloth does not absorb water, does not stick to blood, does not melt and swell, and is not easy to breed bacteria. It is a very good biological material sanitary cloth.

Abstract

The invention discloses a silk chopped fiber manufacturing process. The manufacturing process includes steps of cocoon opening, cocoon selecting, cocoon washing, primary degumming, secondary degumming, spin-drying, scattering, carding and chopping into chopped fibers; water-soluble sericin components are completely stripped from silk fibers, and high silk fiber purity is achieved. After the silk fibers are made into finished products contacting with human skin, less proneness to bacterium breeding, water absorption and adhesion to skin, blood and flesh is realized. Therefore, the silk chopped fibers are optimal raw materials for manufacturing adhesive bandages, toilet paper and wound bandages.

Description

technical field [0001] The invention relates to the technical field of silk utilization, in particular to a production process of short silk fibers. Background technique [0002] Silk is a natural fiber that integrates lightness, softness and fineness in nature. It is known as "the second skin of the human body" and is called "the queen of fibers" by the industry. Its main component is pure natural animal protein fiber. Its structure is the closest to human skin, 87% of which are exactly the same. effect. [0003] Silk is smooth, breathable, soft, moisture-absorbing, non-itchy, and anti-static, making it an excellent material for making skin-friendly products; and because silk is attached to the surface of sericin, it will slightly dissolve when exposed to moisture at temperatures above 38°C; Sericin is an extremely nutritious substance that will accelerate the growth of bacteria. Therefore, when it is used as a medical material that is close to the skin, it may accelerate...
