[0049] Put the gelatin (food grade) raw material into the reaction kettle, add 10 times the weight of deionized water, heat in a water bath at 50-65°C, stir and dissolve, and then prepare the gelatin aqueous solution for use;

[0050] Take 100Kg of edible gelatin aqueous solution and put it into a reaction kettle, heat and stir in a water bath at 50-55°C and dissolve to prepare a solution. Add 0.1Kg of glycerol (softener) to the solution, add 1Kg of siloxane defoamer, heat and stir in a water bath at 50-55°C, add 0.5Kg of melamine, add Kh-560 to 0.1-0.2Kg, keep warm Stir for 4-7 hours until filaments appear when dripping, which is gelatin cross-linked spinning liquid. The gelatin cross-linking spinning liqui...

Embodiment 2

[0052] Raw materials: gelatin (industrial grade). Solvent: deionized water. Cross-linking agent: Kh-560. Glycerol (softener, technical grade), silicone defoamer (composed of polydimethylsiloxane and silicon dioxide, technical grade), melamine (technical grade).

[0053] Take gelatin (industrial grade) raw material and put it into a reaction kettle, add 10 times the weight of deionized water, heat and dissolve in a water bath at 55-60°C with stirring to prepare a gelatin solution, and set it aside.

[0054] Take 100Kg of industrial gelatin aqueous solution, put it into a reaction kettle, add 0.1Kg of glycerol (softener) to the solution, add 1Kg of silicone defoamer, heat and stir in a water bath at 55-60°C, and add melamine 0.5 Kg, add Kh-560 to 0.1-0.2Kg, keep warm and stir for 4-7 hours, until filaments appear when dripping, it is gelatin cross-linking spinning liquid. The spinning liquid passes through the spinneret, sprays out silk, and then dries. The gelatin cross-lin...

Embodiment 3

[0056] Raw material: gelatin (food grade). Solvent: deionized water. Cross-linking agent: Kh-560 (industrial grade). Glycerol (softener, technical grade), silicone defoamer (composed of polydimethylsiloxane and silicon dioxide, technical grade), melamine (technical grade).

[0057] Put the gelatin (food grade) raw material into the reaction kettle, add 8 times the weight of deionized water, heat in a 50-65°C water bath, stir and dissolve, and then prepare the gelatin aqueous solution for use;

[0058] Take 100Kg of edible gelatin aqueous solution and put it into a reaction kettle, heat and stir in a water bath at 50-55°C and dissolve to prepare a solution.

Abstract

The invention provides a degradable spinning material and a preparation method thereof. The material takes gelatine and a small quantity of melamine as raw material and is prepared by certain crosslinking technology, can satisfy the requirement of daily clothes, and has no pollution in the production and use processes. The product is degradable after used, so that the degradable spinning material is safe and healthy to use. The material takes gelatine as raw material. The preparation method comprises the following steps: putting the raw material into a kettle; adding deionized water the weight percent of which is 8-10 times of the ram materials; heating by a water bath of 50-65 DEG C; after stirring and dissolving, preparing the aqueous solution of gelatine for later use; adding 100 parts by weight of aqueous solution of gelatine into the kettle; adding 0.1-0.2 part by weight of glycerol and 1-2 parts by weight of polysiloxane defoamer; heating by a water bath of 50-65 DEG C; under the condition of stirring, adding 0.5-1 part by weight of melamine and 0.1-0.3 part by weight of crosslinker Kh-560; keeping temperature, and stirring for 3-9 hours until filaments is dripped and drawn out; and obtaining the gelatine crosslinking spinning solution.

Description

1. Technical field: [0001] The invention relates to a new degradable spinning material for clothing and a preparation method thereof. The material is a degradable and environmentally friendly new clothing spinning material developed from edible gelatin (Edible Kglutin) or industrial gelatin (Industry Kglutin) , has some characteristics of natural silk cotton, has a certain affinity to the skin, has no side effects, is a good material to replace chemical fiber products, and plays an important role in the development of green spinning. 2. Background technology: [0002] Gelatin is made from cattle, pigs and other animal bones and leather industrial wastes. After a series of pretreatments and purifications, the collagen is extracted, degraded appropriately, and then thermally denatured. Gelatin is both a protein and a polymer biomaterial. [0003] Gelatin is a typical polypeptide chain amphoteric polymer electrolyte, and the side chain group is highly reactive. Gelatin is sol...
