Soft antibacterial non-woven fabric and preparing method thereof

Abstract

The invention belongs to the technical field of non-woven fabric preparing, and particularly relates to soft antibacterial non-woven fabric and a preparing method thereof. The soft antibacterial non-woven fabric is formed through mixing of cotton fibers and polypropylene staple fibers, the proportion of the cotton fibers in the soft antibacterial non-woven fabric is 75 to 80wt%, and the balance isthe polypropylene staple fibers; the polypropylene staple fibers are fine denier fibers, and contain a silver-loaded chitosan antibacterial agent, the adding amount of the silver-loaded chitosan antibacterial agent in the polypropylene staple fibers is 5 to 10wt%, the prepared non-woven fabric has the good antibacterial property, meanwhile, through soft arranging in the physical manner, softnessis good, treatment without a softening agent is achieved, and no softening agent remains.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabric preparation, in particular to a soft antibacterial nonwoven fabric and a preparation method thereof. Background technique [0002] Woven fabric, also known as non-woven fabric, is composed of oriented or random fibers, and is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Antibacterial non-woven fabric is a new generation of environmentally friendly materials. This type of product has the advantages of high strength, excellent protective performance, breathable comfort, environmental protection, non-toxic and tasteless, etc. Excellent, but antibacterial substances will seriously affect the softness of non-woven fabrics, resulting in the technical defect of poor softne...

Problems solved by technology

Antibacterial non-woven fabric is a new generation of environmentally friendly materials. This type of product has the advantages of high strength, excellent protective performance, breathable comfort, environmental protection, non-toxic and tasteless, etc. Excellent, but antibacterial substances will seriously affect the softness of non-woven fabrics, resulting in technical defects of poor softness in non-woven fabrics

[0003] There are also some solutions in the prior art. For example, the Chinese patent with application number CN201911164699.4 makes polypropylene fibers from polypropylene masterbatch; Spraying soybean fiber short fibers on the propylene fiber to obtain a fiber web; performing the first hot rolling on the fiber web to obtain a non-woven fabric; finishing the non-woven fabric to obtain a non-woven fabric; performing a second hot-rolling on the non-woven fabric to obtain a non-woven fabric Skin-soft non-woven fabrics, but this solution only considers the softness of non-woven fabrics, and fails to guarantee the antibacterial and antibacterial properties of non-woven fabrics during storage and use. There are still shortcomings in this solution; for example, the application number is CN201810960296. X's Chinese patent includes the following steps: (1) After mixing N,N-dimethylaminoethyl acrylate and tert-butylaminoethyl methacrylate, continue to add absolute ethanol as a solvent to it, and stir evenly with, Add an initiator, heat up, condense and reflux, rinse with deionized water, and dry to obtain a white powdery antibacterial agent; (2) α-Arbutin, sodium stearoyl lactylate, octylphenoxypolyethyleneoxy Add it into acetone to make a softener; (3) mix the antibacterial agent, softener, dispersant and acetone evenly to make a non-woven fabric finishing solution; (4) soak the non-woven fabric in the non-woven fabric finishing solution at room temperature After soaking in the liquid, the non-woven fabric is taken out, pre-dried, rinsed with deionized water, and dried to obtain a soft antibacterial non-woven fabric. In this scheme, the softness of the non-woven fabric is improved while maintaining a good Antibacterial, but the softness of non-woven fabrics is obtained through softener treatment, which may cause softness and residues on the surface of non-woven fabrics, which will have adverse effects during use
