Embodiment 1

[0024] A kind of antibacterial non-woven fabric, the surface of non-woven fabric is provided with antibacterial film-forming agent layer, is prepared by following method:

[0025] (1) Preparation of polymer film-forming agent

[0026] The polymer film-forming agent is made of the following raw materials in mass percentage: 80% of polyacrylate emulsion, 10% of polyhexamethylene guanidine, and 10% of polyvinylpyrrolidone. The above-mentioned raw materials are mixed to prepare the polymer film-forming agent. The viscosity of the polymer film-forming agent is 50cp; the solid content is 5%, and the liquid rate of the film-forming agent is 10% (based on the dry weight of the non-woven fabric).

[0027] (2) After the non-woven fabric is formed, the polymer film-forming agent is coated on the front and back of the non-woven fabric by a roll coating method. The roller coating method can use the roller commonly used in printing and dyeing as a tool with liquid for roller coating. The l...

Embodiment 2

[0029] A kind of antibacterial non-woven fabric, the surface of non-woven fabric is provided with antibacterial film-forming agent layer, is prepared by following method:

[0030] (1) Preparation of polymer film-forming agent

[0031] The polymer film-forming agent is made of the following raw materials in mass percentage: 85% of polystyrene emulsion, 5% of benzethonium chloride, and 10% of polyvinylpyrrolidone. The above-mentioned raw materials are mixed to prepare the polymer film-forming agent. The viscosity of the polymer film-forming agent is 100cp; the solid content is 20%, and the liquid rate of the polymer film-forming agent is 10%.

[0032] (2) After the non-woven fabric is formed, the polymer film-forming agent is coated on the front and back of the non-woven fabric by a roll coating method. The roller coating method can use the roller commonly used in printing and dyeing as a tool with liquid for roller coating. The liquid tank is located under the roller, which ca...

Embodiment 3

[0034] A kind of antibacterial non-woven fabric, the surface of non-woven fabric is provided with antibacterial film-forming agent layer, is prepared by following method:

[0035] (1) Preparation of polymer film-forming agent

[0036] The polymer film-forming agent is made of the following raw materials in mass percentage: 90% of polyacrylate emulsion, 4% of triclocarban, and 6% of polyvinylpyrrolidone. The above-mentioned raw materials are mixed to prepare the polymer film-forming agent. The viscosity of the polymer film-forming agent is 100cp, the solid content is 15%, and the liquid rate of the film-forming agent is 20%.

[0037] (2) After the non-woven fabric is formed, the polymer film-forming agent is coated on the front and back of the non-woven fabric by a roll coating method. The roller coating method can use the roller commonly used in printing and dyeing as a tool with liquid for roller coating. The liquid tank is located under the roller, which can evenly roll-coa...

Abstract

The invention provides an antibacterial non-woven fabric and a preparation method thereof. Both the upper surface and the lower surface of the antibacterial non-woven fabric are provided with antibacterial film-forming agent layers; each antibacterial film-forming agent layer is obtained by thermally curing a polymer film-forming agent; the polymer film-forming agent has the viscosity of 50-20,000cp and the solid content of 5-55 percent; the film-forming agent has the fluid rate of 2-20 percent; and the polymer film-forming agent is prepared from the following raw materials in percentage by mass: 80-94 percent of a high polymer emulsion, 1-10 percent of a bacteriostatic agent and 5-10 percent of an addition agent. The polymer film-forming agent is selectively roller-coated on the non-woven fabric after the non-woven fabric is formed, so that an antibacterial effect of the non-woven fabric is improved, the antibacterial time is prolonged, and the really long-term antibacterial purpose is achieved.

Description

technical field [0001] The invention belongs to the field of non-woven fabric manufacturing, and in particular relates to an antibacterial non-woven fabric and a preparation method thereof. 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. Low cost, recyclable and so on. Polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because it has the appearance and certain properties of cloth. Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. , it is not made of yarns interwoven and knitted to...
