Problems solved by technology

[0004] Forsythia is the dried fruit of Forsythia suspensa (Thunb.) Vahl in the family Oleaceae (Oleaceae), which has pharmacological effects such as antibacterial, cardiotonic, diuretic, and antiemetic. It is the main raw material of traditional Chinese medicine preparations such as Shuanghuanglian Oral Liquid, Shuanghuanglian Powder Injection, Qingrejiedu Oral Liquid, Liancaojiere Oral Liquid, Yinqiaojiedu Granules, etc. , but there is no documented use of forsythia extract in textiles

Embodiment 1

[0019] Example 1 A preparation method of natural antibacterial textiles containing forsythia extract

[0020] (1) Preparation of microcapsules: Weigh 10 parts of forsythia extract, 1 part of polyvinyl alcohol, 30 parts of glutaraldehyde, and 2 parts of emulsifier, mix the forsythia extract and polyvinyl alcohol aqueous solution, mix well and inject The continuous phase of 1 part of emulsifier was emulsified in n-hexane at high speed at a speed of 700r / min to prepare emulsion A; mix glutaraldehyde with 5 drops of 10% hydrochloric acid aqueous solution, mix well and pour into another part of continuous phase containing 1 part of emulsifier High-speed emulsification in n-hexane at a speed of 700 to prepare emulsion B; mix the two emulsions A and B at 10°C, stir at high speed for 0.5h, filter, wash with petroleum ether three times, and freeze-dry at -10°C to obtain microcapsules;

[0021] (2) Use the printing method to fix the microcapsules on the base fabric:

Abstract

The invention relates to a natural antibacterial textile containing fructus forsythiae extractive. The textile comprises a base cloth and a microcapsule attached to the base cloth fiber, wherein the microcapsule is prepared from fructus forsythiae extractive, polyvinyl alcohol, glutaraldehyde and emulsifier. The textile prepared by the invention has strong antibacterial activity and characteristics of safety, environmental friendliness and washing resistance; besides the preparation technology is simple and suitable for large scale industrialized 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...
