This invention discloses a long-lasting antibacterial and mildew-resistant artificial leather, relating to the field of artificial leather preparation technology. It comprises a base fabric layer, a foaming layer, and a surface treatment layer sequentially composited. The foaming layer is prepared from the following raw materials in parts by weight: 100 parts polyvinyl chloride resin, 40-80 parts plasticizer, 2-8 parts stabilizer, 1-10 parts foaming agent, 0.5-8 parts antibacterial and mildew-resistant composite agent, and 1-10 parts additives. The antibacterial and mildew-resistant composite agent includes a supported inorganic antibacterial agent and an organic mildew-resistant agent. The supported inorganic antibacterial agent is one or more of silver-loaded zeolite, silver-loaded zirconium phosphate, nano-zinc oxide, and nano-copper oxide. This invention employs a dual-layer structure design where the foaming layer and surface treatment layer synergistically support the antibacterial and mildew-resistant composite agent, enabling the antibacterial active components to form a reservoir within the material and continuously exert their effects on the material surface, thereby significantly improving the long-lasting antibacterial and mildew-resistant performance of the artificial leather.

This invention proposes an ultralight yarn to address the problems of poor practicality, high material cost, and easy deformation of existing monofilaments. Using I-shaped PET fibers as raw material, it is prepared through specific spinneret orifices and processes. The monofilament consists of a first horizontal section, a vertical section, and a second horizontal section, with the I-shaped monofilaments interlaced and combined. Different parameters are designed for the length, width, and corner radius of each section. By controlling the angle distribution of the I-shaped spinnerets and optimizing the spinneret parameters, the fiber becomes ultralight and its performance is improved. The I-shaped design disperses stress, heat treatment optimizes performance, and the concentric spinneret orifice distribution ensures quality. This invention achieves lightweight and multifunctionality while maintaining fiber strength and elasticity, resulting in significant economic benefits and broad market prospects.

The present application relates to the technical field of bioengineering, and particularly relates to a fermented liquid of Gomphrena yatschekii, a fermentation method and application thereof.The present application provides a fermentation method of Gomphrena yatschekii, comprising the following steps: (1) mixing Gomphrena yatschekii with mixed enzymes for enzymolysis, and sterilizing to obtain an enzymolysis liquid of Gomphrena yatschekii; (2) mixing the enzymolysis liquid of Gomphrena yatschekii with a compound microbial agent for fermentation, and filtering and sterilizing after fermentation to obtain a fermented liquid of Gomphrena yatschekii; the compound microbial agent is Lactobacillus plantarum LZU-J-TSL6 and Lactobacillus plantarum LZU-J-QA25.After fermentation by the method, the effective components in Gomphrena yatschekii are fully dissolved, the drug activity is improved and increased, the body can rapidly absorb the drug, inflammation and oxidative stress can be regulated, and gastric ulcer can be resisted.

The application relates to the technical field of layered composite fabrics, and discloses a layered composite fabric based on an anti-ultraviolet coating, a preparation method and application in sunshade fabrics, the preparation method of the layered composite fabric based on the anti-ultraviolet coating comprises the following steps: in-situ growth of zirconium-doped nano cerium oxide on a polydopamine modified ZIF-L surface, then modification with a silane coupling agent to obtain a surface-modified ZIF-L hybrid nanomaterial; the surface-modified ZIF-L hybrid nanomaterial is treated with a modifier and 1-chlorohexane to obtain a functional filler; an anti-ultraviolet emulsion containing the functional filler is used to treat a polyacrylonitrile base cloth to form an anti-ultraviolet coating, so that a sunscreen fabric is obtained; and the polyester base cloth fabric, the antibacterial fabric and the sunscreen fabric are compounded to obtain the layered composite fabric based on the anti-ultraviolet coating; the product is excellent in water-proofness, sun-proofness, antibacterial and mildew-proofness and mosquito-repelling effect, and can be used in outdoor or indoor sunshade fabrics.

This invention relates to the field of medical pharmaceutical technology, and in particular to the application of peony oil in the preparation of a drug for treating benign prostatic hyperplasia (BPH). The preparation method of the peony oil includes the following steps: selecting peony plants, peeling peony seeds from the plants as raw materials, crushing and grinding the dried peony seeds using a crushing device to obtain granular raw materials, placing the granular raw materials in a container and adding an organic solution, soaking them in a cool place, then heating and refluxing for extraction, collecting the volatile oil to obtain peony oil, and filtering the peony oil through multiple layers to form peony oil. The application of this peony oil in the preparation of a drug for treating BPH utilizes abundant raw materials for peony oil extraction, and the preparation method is simple and low-cost. Peony flowers are used as the sole active ingredient in the extraction of peony oil, which can be effectively used to treat BPH, expanding the medicinal value of peony flowers and alleviating the suffering of patients during their illness.
