This invention discloses an anaerobic biodegradable masterbatch for cast film of sanitary materials, characterized in that its main components, by mass percentage, include: 0.5-3% cypermethrin, 3-6% copper sulfate, 0.1-0.5% metal inorganic salt coating agent, 1-4% ammonium molybdate, 5-10% PLA, 5-10% nano starch, 1-5% carbamide, 7-12% fumed silica, and the balance being a biodegradable resin carrier. The preparation method includes dispersion treatment, centering treatment, structuring treatment, carrier implantation, and plasticizing granulation. The invention also discloses an anaerobic biodegradable cast film for sanitary materials, comprising the following components by mass percentage: 83.4%-97.13% PE-based cast film substrate for sanitary materials, 1-5% PE wax, 1-7.5% degradation masterbatch, 0.15-0.3% dispersant, 0.02-0.2% antioxidant, 0.2-0.6% white oil, 0.5-3% PE grafted maleic anhydride, and 0.2-2% stabilizer. The manufacturing method includes: material preparation, calcium carbonate pretreatment, melting, filtration, and casting. This invention achieves complete anaerobic biodegradation of PE cast leak-proof and breathable films, and also has antibacterial properties during normal use, making it suitable as a breathable film and base film for disposable sanitary materials.

This invention provides a plant-based gel patch and its preparation method. The plant-based gel patch is prepared by mixing and freezing the following components, including modified polyvinyl alcohol, modified chitosan, functionalized borate ester, and distilled water; the preparation method is as follows: (1) modification of chitosan; (2) synthesis of functionalized borate ester; (3) preparation of allyl dihydrocaffeic acid; (4) graft modification of polyvinyl alcohol; (5) molding of the plant-based gel patch; the plant-based gel patch prepared by this invention can be used as a dressing for skin wound healing, and has antibacterial, good adhesion and self-healing ability.

The invention relates to the technical field of raw materials of skin care products, and particularly discloses an acne-removing composition as well as a preparation method and application thereof. The acne-removing composition comprises the following components in parts by mass: 1.32-4.6 parts of a composite extract; 0.01 to 0.02 part of a skin repairing agent; 10 to 20 parts of a humectant; 75.38 to 88.67 parts of a solvent; the composite extract is prepared by compounding codium tomentosum extract, cryptomeria fortunei bud extract, nymphaea tetragona flower extract, reed extract and ganoderma sinensis extract. The acne-removing mask has the advantages that the acne-removing effect is more thorough, and acnes are not easy to relapse.

The application belongs to the field of functional building materials, and particularly relates to an antibacterial cement mortar with Bi5O7I / BiOBr composite nano-material doped therein, a preparation method of the antibacterial cement mortar, and application of the antibacterial cement mortar in bacteriostasis, antibiosis and improvement of mechanical strength. The antibacterial cement mortar with Bi5O7I / BiOBr composite nano-material doped therein is composed of Bi5O7I / BiOBr composite nano-material, water, cement and sand; the mass of the Bi5O7I / BiOBr composite nano-material is 0.5% to 1.5% of the mass of the cement. The Bi5O7I / BiOBr composite nano-material is constructed, introduced into a cement-based material system to prepare the antibacterial cement mortar, so that the antibacterial cement mortar has antibacterial performance and mechanical strength is significantly improved.

The utility model provides a kind of lyocell hemp jeans fabric, including perspiration wet layer, moisture-permeable layer and microchannel structure, perspiration wet layer is by cotton / lyocell blended warp and lyocell / hemp blended weft yarn alternative beating weft interwoven, moisture-permeable layer is by first warp and first weft yarn alternative beating weft interwoven, first warp uses cotton / lyocell blended yarn, first weft yarn uses lyocell / hemp blended yarn, microchannel structure is set between perspiration wet layer and moisture-permeable layer and is used to guide moisture from perspiration wet layer to moisture-permeable layer flow, perspiration wet layer, microchannel structure and moisture-permeable layer are sequentially arranged from inside to outside.The utility model sets up microchannel structure between perspiration wet layer and moisture-permeable layer, guides moisture from perspiration wet layer to moisture-permeable layer flow, not only increases the wet path of fabric, is favorable to improve wet efficiency, by setting microchannel structure also can enhance air permeability, with good practicability.
