The invention discloses a traditional Chinese medicine insole. The insole comprises a hollow layer of styrene-butadiene latex, and there is deodorant traditional Chinese medicine powder in the hollow layer. The deodorant traditional Chinese medicine powder is composed of the following raw materials in parts by weight: Sophora flavescens 25-35, Phellodendron 25-35, Purslane 25-35, Plantain 25-35, Atractylodes 10-20, Phellodendron 10 ‑20, Fructus Cnidii 10‑20, dry alum 10‑20, the present invention uses phenothiazine-modified methyl methacrylate as a monomer, which can effectively improve the weather resistance of polymers, and phenothiazine has a good The insect repellent performance of the finished shoe sole can also be endowed with a certain insect repellent property. The present invention uses light calcium carbonate doped polymers, which can further improve the mechanical strength of the finished insole and increase the elongation at break.

The invention relates to a method for producing blended yarn of Shengma fiber and cotton. A required cone yarn is produced by selecting suitable Shengma fibers and cotton fibers, combining the Shengma fibers with a cotton comber on a drawing after blowing, carding and predoubling, and performing a roving process, a spinning process and a winding process. In the method, the blowing process has thecharacteristics of carding more and beating less, catching frequently and rarely, low beater speed, less fly fiber, and heavier pressure; the carding process has the characteristics of suitable carding; the drawing process has the characteristics of light quantitation, heavy pressure, low speed, primary predoubling and secondary blending; the roving process has the characteristics of light quantitation, heavy pressure, low speed and high twisting degree; and the spinning process has the characteristics of low speed, high twist factor and suitable temperature and humidity. A plus material of the blended yarn of the Shengma fiber and the cotton produced by the method of the invention has cotton texture; a fabric has the characteristics of soft, smooth and fluffy handfeel, high moisture adsorption performance and ventilation property, high warmth retention property, high bacteria and mildew resistance, high drapability, bright color and luster, plump and smooth fabric surface organization, lightness and comfort for a wearer, and capacity of being used for knitted underwear, leisure wear, towel supplies, beddings and the like.

The invention relates to a soaking solution for preparing an anti-mold sheet, an anti-mold sheet and a preparation method thereof. The soaking solution for preparing the anti-mildew sheet is composed of A liquid and B liquid; the A liquid is composed of the following components in weight percentage: 0.1-3% of glucose oxidase, 2-10% of glucose, and 34-65% of ethanol , water 30-55%; the B liquid is composed of the following components in weight percentage: essence 0.05-5%, ethanol 95-99.95%. The preparation method of the anti-mold sheet of the present invention is simple, and the obtained anti-mold sheet has good antibacterial and anti-mold effects, and when used in food, it will not cause bitter taste in the food, and the reagents used are completely non-toxic, and long-term use will not affect the health of the body. In direct contact with the fresh food.

The invention discloses a natural antibacterial and anti-mildew type PLA refrigerator fresh-keeping liner and its processing technology. The PLA refrigerator fresh-keeping liner comprises the following raw materials in parts by weight: 40-60 parts of polylactic acid, 20-30 parts of polyethylene glycol , 4-6 parts of glycerin, 6-10 parts of active antibacterial agent, 5-8 parts of natural antifungal agent, 2-6 parts of active antioxidant; processed by the following steps: step S1, preparing modified polylactic acid raw material, Step S2, preparation of mixing materials, step S3, preparation of antibacterial and anti-mildew polylactic acid sheets by hot pressing, step S4, vacuum forming semi-finished liner, step S5, trimming and trimming of semi-finished products to obtain natural anti-bacterial and anti-mildew type The finished PLA refrigerator fresh-keeping liner; the invention solves the problem in the prior art that the refrigerator fresh-keeping liner is prone to mildew and produces bacteria that affects people's health, and at the same time solves the problem that the inner liner is not degradable and pollutes the environment when the refrigerator is scrapped. .
