Problems solved by technology

Phellodendron officinalis mainly contains about 1.6% berberine, and it also contains tetrandrine palmatum, cortexine, jatrorrhizine, phellodendron, kurerine, cochinealine, magnolialine, limonin, etc. About 9% of berberine is isolated from the root bark, and it still contains jatrorrhizine, phellodendronine, and cochinealine. The content of berberine in Sichuan Phellodendron is relatively high, reaching 3%. However, there is no documented use of Cork Phellodendron extracts for textiles

Abstract

The invention relates to an amur corktree bark extract-containing natural antibacterial textile. The amur corktree bark extract-containing natural antibacterial textile comprises a base cloth and microcapsules attached to base cloth fibers, wherein the microcapsules are prepared from amur corktree bark extract, polyvinyl alcohol, glutaraldehyde and an emulsifier. The amur corktree bark extract-containing natural antibacterial textile has the advantages of strong antibacterial activity, safety, environmentally friendly characteristic, washing resistance, simple preparation processes and good adaptability for industrialized large-scale production.

Description

technical field [0001] The invention relates to a textile, in particular to a textile with a natural antibacterial function. Background technique [0002] Microorganisms are ubiquitous in nature, and they multiply rapidly under suitable conditions. One bacterium will become 8 million in 8 hours. The human body is an ideal growth environment for microorganisms. Textiles will stick to human secretions such as sweat and sebum during wearing. These are the nutrients necessary for the growth of microorganisms. The porous shape of textiles is also conducive to the attachment of microorganisms. Therefore, textiles are Good medium for bacterial growth and reproduction. Under normal circumstances, we do not feel the harm of bacteria, but the excessive reproduction of bacteria will produce odor, and cause harm to human health through the skin, respiratory tract, digestive tract and blood, which can lead to dermatitis and other infectious diseases . In recent years, the SARS cri...
