Description

Technical Field

[0001] This utility model relates to the field of flame-retardant nonwoven fabric technology, specifically to a flame-retardant nonwoven fabric. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming a web from polymer chips, short fibers, or filaments through airflow or mechanical means, followed by hydroentangling, needle punching, or thermal rolling for reinforcement, and finally finishing processes to form a non-woven fabric. Flame-retardant polyester nonwoven fabric, which possesses flame-retardant properties, is mainly composed of polyester. Viscose fiber is a chemical fiber, a polymer product of terephthalic acid or diethyl terephthalate and ethylene glycol. Its characteristics include: high strength, good elasticity, good heat resistance, smooth surface, good abrasion resistance, good light resistance, corrosion resistance, and poor dyeability. Its flame-retardant mechanism mainly relies on the addition of flame retardants, which are material additives. Flame-retardant nonwoven fabrics are generally used in polyester plastics and textiles. They are added to polyester to increase the ignition point of the material or to hinder its combustion, thereby improving the fire safety of the material. Polyester flame-retardant nonwoven fabrics are mainly used in soft furniture, mattresses, toys and home textile products. At present, when polyester flame-retardant nonwoven fabrics are used in the flame-retardant protection of soft furniture, they are basically single-layer structures. Although they can have a flame-retardant effect when exposed to open flames, they cannot block the high temperature generated by the open flame. The high temperature generated by the open flame can easily penetrate the polyester flame-retardant nonwoven fabric and come into contact with the inner furniture to be protected. After the open flame occurs, the probability of damage to the inner furniture is relatively high, and the practical performance needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to provide a flame-retardant nonwoven fabric to solve the problem mentioned in the background art that when polyester flame-retardant nonwoven fabric is used for flame-retardant protection of soft furniture, it is basically a single-layer structure. Although it can have a flame-retardant effect when exposed to open flames, it cannot block the high temperature generated by the open flame. The high temperature generated by the open flame can easily pass through the polyester flame-retardant nonwoven fabric and come into contact with the inner furniture to be protected. After the open flame occurs, the probability of damage to the inner furniture is relatively high, and the practical performance needs to be improved.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flame-retardant nonwoven fabric, comprising a base fabric layer, wherein an enhancement layer is provided on the inner side of the base fabric layer;

[0005] The enhancement layer includes a heat insulation layer, sewing thread, metal wire, and coating.

[0006] The heat insulation layer is located on the inner surface of the base fabric layer. The heat insulation layer is sewn to the base fabric layer by sewing thread. The interior of the heat insulation layer is mixed with metal wires. The coating is set on the outer surface of the base fabric layer.

[0007] Preferably, the density of the multiple sewing threads is 5-12 threads per square inch.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This flame-retardant nonwoven fabric has the following advantages over traditional technology:

[0009] By combining the base fabric layer and the enhancement layer, when the base fabric layer with the enhancement layer is laid out and exposed to open flame, both the coating and the base fabric layer have certain flame-retardant properties, which can reduce the chance of damage to the furniture wrapped inside the base fabric layer after the open flame is laid out. At the same time, the high temperature generated by the open flame will be blocked by the heat insulation layer, which can reduce the chance of damage to the furniture inside the open flame, thus enhancing the practical performance.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2This utility model provides a technical solution: a flame-retardant nonwoven fabric, comprising a base fabric layer 1, which is a polyester flame-retardant nonwoven fabric with certain flame-retardant properties. An enhancement layer 2 is provided on the inner side of the base fabric layer 1. The enhancement layer 2 includes a heat insulation layer 201, sewing thread 202, metal wire 203, and a coating 204. The heat insulation layer 201 is located on the inner surface of the base fabric layer 1 and is made of ceramic fiber cloth, possessing certain heat insulation properties. The heat insulation layer 201 is sewn to the base fabric layer 1 by the sewing thread 202, which is made of polyester thread capable of withstanding friction and dry cleaning, and has low elongation. The high strength and low elongation ensure excellent sewing quality. The insulation layer 201 is internally blended with metal wires 203, which are stainless steel filaments with metal memory properties. This means that after the metal is deformed, it can still maintain its deformed state after the external force that caused the deformation is removed. The coating 204 is applied to the outer surface of the base fabric layer 1. The coating 204 is a water-based PU flame-retardant adhesive layer. The density of the multiple sewing threads 202 is 5-12 threads / square inch. The multiple sewing threads 202 are densely distributed, which ensures the sewing strength between the base fabric layer 1 and the insulation layer 201.

[0016] In the process of using flame-retardant nonwoven fabric, before the base fabric layer 1 is put into use, the operator first lays the heat insulation layer 201, which is internally blended with metal wires 203, on the inner surface of the base fabric layer 1. Then, the heat insulation layer 201 and the base fabric layer 1 are sewn together using sewing thread 202. Finally, the coating 204 is evenly sprayed on the outer surface of the base fabric layer 1. At this point, the base fabric layer 1 with the enhancement layer 2 can be laid and used. During the laying process, because the metal wires 203 internally blended in the heat insulation layer 201 have a certain metal memory property, the heat insulation is enhanced. After being bent and deformed, layer 201 can maintain its bent shape, which makes it easier for the insulation layer 201 to fit into furniture with folded grooves. This provides convenience for operators in laying, installing and using the product. When exposed to open flames after installation, both coating 204 and base fabric layer 1 have certain flame-retardant properties, which can reduce the chance of open flames damaging the furniture wrapped inside the base fabric layer 1. At the same time, the high temperature generated by open flames will be blocked by the insulation layer 201, which can reduce the chance of high temperature from open flames damaging the furniture inside, thus enhancing its practicality.
