Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically a composite nonwoven fabric with good waterproof performance. Background Technology

[0002] Nonwoven fabric, also known as non-woven textile, is made from oriented or randomly arranged fibers through friction, cohesion, bonding, or a combination of these methods. Unlike woven fabrics, the fibers in nonwoven fabric cannot be pulled apart into individual threads, which is a key characteristic distinguishing it from other fabrics. The raw materials for nonwoven fabric production are diverse, including chemical fibers such as polyester, polyamide, polyacrylonitrile, and viscose, as well as natural fibers such as cotton, linen, wool, and silk. Nonwoven fabric has many advantages, such as being lightweight, soft, breathable, non-toxic, non-irritating, antibacterial, and resistant to chemical agents. It is also an environmentally friendly material with low pollution levels after disposal.

[0003] Non-woven fabrics themselves are not waterproof; they require special treatment to achieve a waterproof effect. Therefore, there are two main existing methods for achieving waterproofing with non-woven fabrics: surface coating and adding a layer of PVC material. Surface coating involves covering the non-woven fabric surface with a waterproof membrane, which effectively prevents water penetration. Adding a layer of PVC material involves adding a PVC coating to the non-woven fabric surface. PVC itself has waterproof properties, further enhancing the waterproof effect of the non-woven fabric. In addition, "one layer, three coats" is another common waterproofing method, which involves applying three coats of waterproof coating to a single layer of non-woven fabric or mesh fabric to achieve waterproofing.

[0004] However, whether it is surface coating or adding a layer of PVC material, waterproofing can only be achieved on the surface of the non-woven fabric. The cut ends of the non-woven fabric are not waterproof, which makes the non-woven fabric lack all-round waterproofing effect, leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a composite nonwoven fabric with good waterproof performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite nonwoven fabric with good waterproof performance, comprising an outer layer and an inner layer, wherein both sets of the outer layers cover the sidewalls of the inner layer, and the inner layer comprises a waterproof inner seat and a waterproof outer seat, wherein the interior of the waterproof inner seat and the waterproof outer seat are filled with sealing adhesive.

[0010] As a further embodiment of this utility model: a composite nonwoven fabric with good waterproof performance, wherein the glue used for filling is 502 glue.

[0011] As a further embodiment of this utility model: a composite nonwoven fabric with good waterproof performance, wherein an inner seat thin ring is fixedly installed on the side wall of the inner seat partition, and both the inner seat thin ring and the outer seat partition are made of low-cost and highly sensitive polypropylene film material.

[0012] As a further improvement of this utility model: a composite nonwoven fabric with good waterproof performance, wherein the thickness of the inner seat thin ring and the outer seat partition is 0.1cm.

[0013] As a further embodiment of this utility model: a composite nonwoven fabric with good waterproof performance, wherein the outer layer includes a nonwoven fabric and a gasket, one side of the gasket is bonded to the nonwoven fabric with environmentally friendly adhesive, and the other side of the gasket is bonded to the inner layer with environmentally friendly adhesive.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
