The invention relates to a method for producing water-soluble sericin proteins with different molecular weights by using silkworm cocoons as raw materials. The cleaned cocoon shells, waste silk, etc. are immersed in water or slightly alkaline solution, and after high temperature and high pressure degumming treatment, an insoluble sericin solution is obtained, and the pH value of the solution is adjusted to 8-12, and then the second High temperature and high pressure degradation treatment, by adjusting the process conditions such as temperature or pressure during degradation treatment, treatment time, pH range of degumming solution, etc., to control the molecular weight of water-soluble sericin required to achieve, so as to prepare easily water-soluble silk for different purposes Colloid solution or powder, used in biomaterials, textile finishing agents, health care products, cosmetics, polymer synthetic materials and other fields.

The invention provides a type of aliphatic diisocyanate with a novel chemical structure, which is C21-36 aliphatic diisocyanate, has the same excellent performance with other traditional aliphatic isocyanates, and is used for preparing polyurethane varnish, coating, elastomer, adhesive, textile finishing agent, rocket propellant and the like. The invention also provides a preparation method of this type of substance, which comprises the following steps that: (a) unsaturated dicarboxylic acid with a special structure or the ester solution thereof are catalyzed and hydrogenised to prepare saturated diacid; (b) the saturated diacid is dissolved into inert solvent and added with chloride agent to react and prepare binary acid chloride; (c) sodium azide is added in to react and prepare the corresponding azide; and (d) the azide is isomerized and decomposed to prepare an aliphatic diisocyanate crude product. The method is characterized by lower condition requirements, safety, environmental-friendliness, fewer side effects, high yield and easy wide popularization in industry.

The invention belongs to the field of textile finishing agents, in particular to a long-acting antibacterial, deodorizing and deodorizing finishing agent for woolen sweaters. It includes components at the following concentrations: 8-12g / L DCMX-coated microcapsules, 20-30g / L aluminosilicate, 50-60g / L binder, 30-40g / L softener , 10‑15g / L penetrating agent, 2‑6g / L dispersant. The technical scheme provided by the present invention makes the woolen sweater after its finishing have very ideal antibacterial, deodorizing and deodorizing effects through the synergistic effect of the microcapsules coated with DCMX and aluminosilicate. Adhesive, so that the above effects still maintain a high antibacterial and deodorizing effect after repeated washing.

The invention relates to the field of textile cultural relics protection, and discloses a method for preparing an antibacterial textile finishing agent by using ursolic acid extract. The invention combines the two-phase extraction method and the microwave extraction method to shorten the extraction time and improve the extraction efficiency. The present invention adopts (NH 4 ) 2 SO 4 The mixed solution of solution and ethanol is used as the extraction agent, which is beneficial to reduce the viscosity and improve the diffusion ability and solubility of the liquid, so that the extracted ursolic acid content increases. In the present invention, ursolic acid and nano-zinc oxide are used as antibacterial agents to improve the antibacterial activity of textiles, and simultaneously, 3 (trimethoxysilyl) propyl dimethyl octadecyl ammonium chloride is added in the preparation process of textile finishing agents and 3-imino-N-nitrided acetamidobutyrolactam, so that the finishing agent can not only chemically combine with the cellulose fiber, but also polycondensate into a film, so that the antibacterial component of the finishing agent has washing resistance.
