Problems solved by technology

[0005] However, in the prior art, most non-woven fabrics are formed by spunlace treatment. During the spunlace treatment process, it is difficult to ensure that uniform through holes can be formed between the fibers of the non-woven fabric, so it is difficult to meet the high requirements of practical applications.

Embodiment 1

[0037] A kind of preparation method of antibacterial spunlace nonwoven fabric, comprises following preparation steps:

[0038] First, prepare antibacterial non-woven monomer fibers:

[0039] a) Take alkali-resistant glass fiber as raw material, mix it with molten polyurethane and antibacterial agent under the action of slitting and shearing, and fully stir to form the surface layer of non-woven monomer fiber; among them, the alkali-resistant glass fiber, polyurethane and antibacterial agent The mixing mass ratio is 1:2:1;

[0040] b) Take nano-scale tea fiber as the core material;

[0041] c) Extrude the core material through the round hole of the extruder die, and extrude the surface layer of the non-woven monomer fiber through the outer ring of the extruder die to obtain the antibacterial non-woven monomer fiber wrapped with the core material.

[0042] Then, antibacterial spunlace nonwovens were prepared based on antibacterial nonwoven monomer fibers.

Abstract

The invention belongs to the technical field of non-woven fabrics and discloses an antibacterial spunlace non-woven fabric and a preparation method thereof. The method comprises the following steps ofperforming opening; performing film covering: stirring and dissolving protein hydrogel to obtain a film coating solution, immersing the opened non-woven fabric monomer fibers into the film coating solution at least once, performing drying, and performing compounding on the surfaces of the non-woven fabric monomer fibers to form a hydrogel film layer with a specified thickness; performing cardingto form a net, wherein the fiber net at least comprises two layers of non-parallel fibers, and the carding of each layer of fibers is as follows: laying, in a flat way, a plurality of non-woven fabricmonomer fibers coated with the hydrogel film layer in parallel through ultrasonic vibration; and performing spunlace molding: placing the carded and molded fiber net on an injector, first carrying out spunlace treatment on the fiber net for 5-10 minutes with a sodium hydroxide solution having the pH value greater than 11.5 and the temperature from 30 DEG C to 85 DEG C, and then carrying out the spunlace treatment on the fiber net for 25-30 minutes with atomized water to prepare the porous antibacterial spunlace non-woven fabric, wherein the uniformity of the sizes of through holes in the non-woven fabric can be effectively ensured based on the steps.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to an antibacterial spunlace nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing The formed non-woven fabric has the advantages of good flexibility, high output, and low cost. In the prior art, the non-woven fabric has been widely used in the fields of medical treatment, clothing and other industries. [0003] Taking the use in the medical field as an example, most of them are used as dressing gauze, so it is necessary to ensure that the non-woven fabric has good antibacterial properties and air permeability; [0004] In addition, taking the utilization in the industri...
