Antibacterial nonwoven fabric and preparation method thereof

Abstract

The invention discloses antibacterial nonwoven fabric and a preparation method thereof. The antibacterial nonwoven fabric is prepared from raw materials in percentage by mass as follows: 40%-60% of polypropylene fibers and 60%-40% of copper modified polyester fibers. The preparation method comprises steps as follows: 1) the polypropylene fibers and the copper modified polyester fibers are weighed according to a formula; 2) raw materials are simultaneously placed in a feed box and automatically and uniformly mixed; 3) the mixed material is carded, and a net-like semi-finished product is obtained; 4) an upper roller and a lower roller are arranged, the temperature of the rollers is set at 120-150 DEG C, and the net-like semi-finished product is conveyed to the rollers for hot pressing; 5) a finished product is obtained. The technological process is simple, and resources are saved; the copper modified polyester fiber has antibacterial, sterilizing, bacteriostatic, deodorizing and anti-mite effects, so that the nonwoven fabric has sterilization efficacy, a good antibacterial effect, a lasting bacteriostatic effect, high stability and safety and good breathability and water absorption, and can be widely applied to the fields of various hygienic auxiliaries of hospitals, home, clothes, masks, baby products and the like.

Description

Technical field [0001] The invention relates to the technical field of non-woven fabric preparation, in particular to an antibacterial non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics are made of chemical fibers and plant fibers on wet or dry papermaking machines under the conditions of water or air as the suspension medium. Although they are cloth and are not woven, they are called non-woven fabrics. Woven fabric is a new generation of environmentally friendly materials, and its applications in different fields usually need to have different characteristics such as strong, antibacterial, waterproof, environmentally friendly, flexible, non-toxic and tasteless, and cheap; all cotton non-woven fabrics are soft and comfortable, and have high skin-friendly properties. Characteristics, it is widely used in household, clothing, medical and sanitary products. However, cotton fiber does not have good antibacterial and adsorption propertie...

Problems solved by technology

[0002] Non-woven fabrics are made of chemical fibers and plant fibers on wet or dry paper machines under the condition of water or air as the suspension medium. Although they are cloth without weaving, they are called non-woven fabrics. Woven fabric is a new generation of environmentally friendly materials. It is usually required to have different characteristics such as strength, antibacterial, waterproof, environmental protection, flexibility, non-toxic and tasteless, and low price in different fields; cotton non-woven fabrics are soft, comfortable, and skin-friendly. It is widely used in home furnishing, clothing, and medical and sanitary products. However, cotton fiber does not have good antibacterial properties and adsorption properties, and is easily damaged by microbial contamination. It needs to be sterilized by adding chemical components or soaking in drugs. Not only is it easy to cause drug resistance of bacteria and other microorganisms and produce mutated strains, but the antibacterial ingredients may enter the human body after dissolution, destroying the micro-ecological balance of the human body, and the safety and stability need to be improved
