Problems solved by technology

Traditional antibacterial non-woven fabrics are mostly bonded together by the base layer and the antibacterial layer through adhesives; however, this bonding structure will contaminate the material itself and cause adverse post-sterilization risks due to the presence of adhesive solvents
The structure is relatively complex, and the antibacterial effect cannot meet people's requirements

Abstract

The invention provides an antibacterial plant cellulose fiber which contains a natural antibacterial plant extract microcapsule. The invention further provides a preparation method of the antibacterial plant cellulose fiber. The method comprises a step of preparing natural antibacterial plant extract emulsifying dispersion liquid, wherein the step of preparing the natural antibacterial plant extract emulsifying dispersion liquid comprises the processes of mixing 5-8 parts of a natural antibacterial plant extract and 10-15 parts of a peach gum solution, heating the mixture to 52-60 DEG C and stirring and emulsifying, wherein the stirring speed is 200-300r / min; and emulsifying and dissolving disperse particles to 1-2 microns. Any organic antibacterial agent or inorganic antibacterial agent is not added, so that the prepared antibacterial plant cellulose fiber is safe and environmentally friendly, can be naturally degraded and has good social significance; and the prepared antibacterial fiber is more lasting in antibacterial effect by adopting a special microcapsule slow-release technology.

Description

Technical field [0001] The invention relates to the field of fiber manufacturing, and in particular to a plant antibacterial cellulose fiber and a preparation method thereof, as well as a medical waterproof non-woven fabric prepared using the fiber. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials that are moisture-proof, breathable, flexible, lightweight, non-combustible, easily degradable, non-toxic and non-irritating, and rich in color. , low price, recyclable and other characteristics. For example, polypropylene (PP material) pellets are often used as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing. It is called cloth because it has the appearance and certain properties of cloth. [0003] Non-woven fabrics are short fibers or filaments that are orie...
