Problems solved by technology

In the article "Polylactic acid fiber modification by grafting polyvinylpyrrolidone on the surface", polyvinylpyrrolidone was grafted on the surface of partially hydrolyzed polylactic acid fiber to obtain a modified polylactic acid fiber with certain water absorption, but this method is not convenient for large-scale production. Large-scale production, and there is still a big gap in the water absorption of fibers compared with absorbent cotton, and further modification is required

Embodiment Construction

[0016] An antibacterial and deodorizing medical cotton swab containing neem oil, which is composed of a cotton swab and a composite fiber cotton wrapped around the end of the cotton swab, and the composite fiber cotton is made of the following parts by weight of raw materials: polylactic acid particles 15, seaweed Carbon 2, polyvinylpyrrolidone 1, neem oil 0.001, sodium alginate 5, dopamine hydrochloride 5, Tris-HCl buffer solution, calcium chloride 6, deionized water 300.

[0017] The preparation method of the composite fiber cotton is:

[0018] (1) The polylactic acid particles are mixed with seaweed charcoal, polyvinylpyrrolidone, and neem oil, mixed at high speed, and then melt-spinning. The spinning temperature is 220 ℃, and the spinning speed is 2500 m / min. 10μm composite polylactic acid fiber spare;

[0019] (2) First take 100 parts by weight of deionized water into the reaction vessel, then add dopamine hydrochloride, stir until it is completely dissolved, add Tris-HCl buffe...

Abstract

The invention discloses an antimicrobial deodorant medical cotton swab containing neem oil. The antimicrobial deodorant medical cotton swab comprises a cotton swab and composite fiber cotton wrapping the end of the cotton swab. The cotton swab uses renewable and degradable composite polylactic acid fiber cotton to replace the traditional absorbent ball so that a production cost is reduced. Through use of seaweed charcoal, polyvinylpyrrolidone and neem oil, the composite polylactic acid fiber has good hydrophilicity and health effects of resisting bacteria, killing injurious insects and promoting wound healing and has good biocompatibility. In addition, the fiber surface is modified with polydopamine-calcium alginate gel so that an adsorption capacity is high and wound cleaning effects are good. A production process of the cotton swab is simple and efficient, materials used in all processes can be recycled, and adverse influence on the environment is avoided.

Description

Technical field [0001] The invention relates to the technical field of medical cotton swabs, in particular to an antibacterial and deodorizing medical cotton swab containing neem oil. Background technique [0002] Medical cotton swabs are a very common medical care product. They are obtained by rolling cotton swabs made of plastic sticks, paper sticks, wooden sticks and so on. The main functions are disinfection, sampling, etc., and they are widely used. Because cotton swabs are in direct contact with the wound, it has high requirements on the quality of absorbent cotton. The absorbent cotton used in traditional medical cotton swabs is mostly obtained by degreasing cotton with lye. Although it has good skin affinity and water absorption, it is It is natural cotton, which is easy to breed bacteria, and the production cost is relatively high. As a result, there are many sterile cotton swabs made of low-quality absorbent cotton on the market, which directly affects the health of use...
