The present application belongs to the field of textile dyeing and finishing technology, and particularly relates to a production method of pure cotton imitated hemp fabric, comprising the following processes: spinning, singeing, desizing, mercerizing, super softening, tentering, super softening, and preshrinking, wherein the spinning process uses 40% pre-spinning recycled cotton and 60% fine cotton to blend, and cotton imitated hemp slub yarn is spun, because the recycled cotton fiber is shorter, the slub length is shorter than the conventional slub, the slub is naturally uniform, and is closer to the appearance of hemp, the fabric has the hand feeling and appearance of hemp, and the wearing comfort is improved by combining the weave, specification design, and finishing process.

This application provides a composite wound dressing and its preparation method, belonging to the field of medical dressing technology. The composite wound dressing includes an outer support layer and an inner functional layer. The outer support layer is a modified ramie fiber nonwoven fabric, the modification including low-temperature plasma treatment and acetylation modification of the ramie fibers. The inner functional layer is a composite of ramie woven fabric and low-antigen collagen sponge grafted with carvacrol. The collagen sponge penetrates the yarn gaps and pores of the woven fabric, forming a structure in which the collagen sponge and ramie fibers mutually wrap and interweave. The dual-layer structure design of the dressing, with its outer support layer and inner functional layer, provides stable mechanical support through the outer layer to maintain the dressing's shape, while the inner layer enables efficient absorption of exudate and sustained release of antibacterial components, actively promoting wound healing. It exhibits excellent biocompatibility and low immunogenicity risk.

The application provides osmanthus fragrans plant extract mosquito repellent spray with long-acting mosquito repellent and itching, swelling relieving effects and a preparation method thereof, and relates to the technical field of mosquito repellent products. The raw materials of the mosquito repellent spray are as follows: osmanthus fragrans flower extract 7-9 parts, melaleuca alternifolia leaf extract 8-11 parts, chrysanthemum artemisia extract 1-2 parts, radix morindae officinalis extract 12-16 parts, platycodon grandiflorum root powder 16-19 parts, plant essential oil 20-24 parts, glycerol 18-23 parts, sucrose stearate 6-9 parts, p-hydroxyacetophenone 0.2-0.5 parts, stabilizer 3-5 parts and peppermint water 110-120 parts. The mosquito repellent spray can interfere with the activities of mosquitoes to achieve a good mosquito repellent effect, and can form a uniform and stable protective film on the skin surface to prolong the mosquito repellent effect, and can also play a good soothing and skin converging role, reduce local inflammatory reactions, promote skin barrier repair, and effectively relieve itching, swelling and other discomforts caused by mosquito bites.
