Description

Technical Field

[0001] The utility model relates to a flame-retardant and antibacterial composite non-woven fabric, belonging to the technical field of non-woven fabrics. Background Art

[0002] Non-woven fabrics, also known as nonwovens, are fabrics that don't require spinning or weaving. Instead, they are made by aligning or randomly arranging textile staple fibers or filaments to form a web structure, which is then reinforced using mechanical, thermal bonding, or chemical methods. These fabrics transcend traditional textile principles and feature a shortened process, fast production, high yield, low cost, a wide range of uses, and diverse raw material sources. Non-woven fabrics are also frequently used in household products, such as wall coverings. These wall coverings are also becoming increasingly popular. Since non-woven fabrics for wall coverings cover a large surface area, their ability to absorb dust particles in the air can improve the indoor environment. Furthermore, these non-woven fabrics are required to have excellent flame retardant and antibacterial properties. Therefore, the challenge is to develop a composite non-woven fabric that is both flame retardant and antibacterial and can also absorb dust from the air. Utility Model Content

[0005] The flame retardant and antibacterial composite non-woven fabric of the utility model comprises a flame retardant non-woven fabric layer, an antibacterial non-woven fabric layer and a bamboo charcoal fiber non-woven fabric layer which are composited by a dot-shaped, line-shaped or mesh-shaped flame retardant adhesive;

[0006] The flame retardant fiber used in the flame retardant non-woven fabric layer includes a fiber body, a polydopamine layer and a ferrosoferric oxide nanoparticle layer.

[0009] On the basis of the above solution and as a preferred solution of the above solution: flame retardant microcapsules are attached to the surface of the antibacterial non-woven fabric on one side close to the bamboo charcoal fiber non-woven fabric layer 3 through a dot-shaped, line-shaped or mesh-shaped flame retardant adhesive.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the flame retardant microcapsule includes a capsule wall and a flame retardant gas filled inside the capsule wall; the capsule wall is made of polyester, and the flame retardant gas is nitrogen, carbon dioxide or helium.

[0011] On the basis of the above solution and as a preferred solution of the above solution: the bamboo charcoal fiber non-woven fabric layer is compounded with a mesh cloth layer on the side away from the antibacterial non-woven fabric layer.

[0012] The beneficial effects of the present invention are as follows: the flame-retardant and antibacterial composite nonwoven fabric of the present invention possesses flame-retardant and antibacterial properties. Furthermore, the ferroferric oxide nanoparticles attached to the surface of the flame-retardant fibers have a good electrostatic effect, which can absorb dust particles in the air.

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combine Figure 1 and Figure 2 , the embodiment is described in detail. The flame-retardant and antibacterial composite non-woven fabric involved in this embodiment includes a flame-retardant non-woven fabric layer 1, an antibacterial non-woven fabric layer 2 and a bamboo charcoal fiber non-woven fabric layer 3, which are compounded by a dot-shaped, line-shaped or mesh-shaped flame-retardant adhesive; the flame-retardant fiber used in the flame-retardant non-woven fabric layer 1 includes a fiber body 11, a polydopamine layer 12 and a ferroferric oxide nanoparticle layer 13. The ferroferric oxide nanoparticles used in the ferroferric oxide nanoparticle layer 13 have good electrostatic effects themselves and therefore have good adsorption properties. The flame-retardant and antibacterial composite non-woven fabric involved in this embodiment can absorb dust in the air when used as a wall cloth, thereby playing a role in improving the living environment.

[0020] Furthermore, the flame-retardant fibers in the flame-retardant nonwoven fabric layer 1 are flame-retardant viscose fibers, aramid 1313 fibers, aramid 1414 fibers, flame-retardant polyester fibers, flame-retardant nylon fibers, or polyacrylonitrile pre-oxidized yarn fibers. In this embodiment, flame-retardant polyester fibers are selected. The flame-retardant nonwoven fabric layer 1 serves as the outermost layer of the wall covering.

[0021] Furthermore, the antibacterial nonwoven layer 2 is a rod-shaped nano zinc oxide / polypropylene nonwoven fabric, which can also be a melt-blown nonwoven fabric with nano silver antibacterial agent attached to the surface. It has a good antibacterial effect and can prevent the growth of bacteria inside the nonwoven fabric.

[0022] Furthermore, flame-retardant microcapsules are attached to the surface of the antibacterial nonwoven fabric 2 on one side near the bamboo charcoal fiber nonwoven fabric layer 3 via a dot-, line-, or mesh-shaped flame-retardant adhesive. The flame-retardant microcapsules include a capsule wall made of polyester and a flame-retardant gas filled within the capsule wall; the capsule wall is made of polyester, and the flame-retardant gas is nitrogen, carbon dioxide, or helium, with carbon dioxide being selected in this embodiment. During combustion, the high temperature of the flame destroys the capsule wall, releasing the flame-retardant gas in the flame-retardant microcapsules. This isolates the flame of the nonwoven fabric from the oxygen in the surrounding air, preventing the fibers of the nonwoven fabric from burning due to the lack of oxygen.

[0023] Example 2

[0024] Combine Figure 3 This embodiment is described in detail. The flame-retardant, antibacterial composite nonwoven fabric of this embodiment differs from the first embodiment in that the mesh fabric layer 4, laminated to the bamboo charcoal fiber nonwoven fabric layer 3 on the side facing away from the antibacterial nonwoven fabric layer 2, increases the strength of the entire nonwoven fabric. Specifically, the mesh fabric layer 4 is made of nylon crack-proof mesh. When this composite nonwoven fabric is glued to a wall covering, it provides a crack-proof effect.

[0025] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
