Abstract

The invention relates to a high-strength waterproof breathable composite non-woven fabric which comprises a first non-woven fabric layer, a second non-woven fabric layer, a wear-resistant layer, a waterproof layer and an anti-tearing layer, wherein the wear-resistant layer is arranged between the first non-woven fabric layer and the waterproof layer, the anti-tearing layer is arranged between the waterproof layer and the second non-woven fabric layer, the waterproof layer is arranged between the wear-resistant layer and the anti-tearing layer, the waterproof layer is a PTFE (polytetrafluoroethylene) film, and the anti-tearing layer is latticed glass fiber yarns. The invention has simple structure, the waterproof layer formed by the PTFE film (polytetrafluoroethylene) can effectively play the role of waterproof and ventilation, the effect is obvious, and the added latticed glass fiber yarn anti-tearing layer can effectively improve the tensile strength and the bending strength of the non-woven fabric, improve the toughness and the mechanical strength of the non-woven fabric, prolong the service cycle of the non-woven fabric, expand the application range of the non-woven fabric and be beneficial to the wide popularization and application of the non-woven fabric.

Description

High-strength waterproof breathable composite non-woven fabric
Technical Field
The invention belongs to the technical field of non-woven fabrics, and particularly relates to a high-strength waterproof breathable composite non-woven fabric.
Background
The non-woven fabrics on the market are the non-woven fabrics, though the non-woven fabrics are called as the non-woven fabrics without weaving, the application field of the existing non-woven fabrics is very wide, the non-woven fabrics are heat-insulating, flame retardant, breathable, tear-proof, radiation-resistant and the like, the non-woven fabrics are various and various, but the application environment is single, the limitation is large, the waterproof effect of most of non-woven fabrics is poor, the non-woven fabrics cannot protect equipment or chemical materials which cannot meet water, the tensile strength of the non-woven fabrics is also poor, the non-woven fabrics are easy to tear due to improper operation in the using process, the damage is caused, and the wide application of the non-woven fabrics is further limited.
Disclosure of Invention
The invention aims to solve the defects and provides the high-strength waterproof breathable composite non-woven fabric.
In order to overcome the defects in the background art, the technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a waterproof ventilative composite nonwoven of high strength, includes first non-woven fabrics layer, second non-woven fabrics layer, wearing layer, waterproof layer and anti-tear layer, the wearing layer sets up between first non-woven fabrics layer and waterproof layer, anti-tear layer sets up between waterproof layer and second non-woven fabrics layer, the waterproof layer sets up between wearing layer and anti-tear layer.
In a preferred embodiment of the present invention, the waterproof layer is a PTFE film (polytetrafluoroethylene), and after the polymer material and the cloth are compounded, the waterproof and air-permeable effects are high.
In a preferred embodiment of the present invention, the anti-tearing layer is a grid-shaped glass fiber yarn, which has high tensile strength, high bending strength and high toughness, and is beneficial to prolonging the service life of the non-woven fabric.
The invention has the beneficial effects that: simple structure, it is practical convenient, the waterproof layer that utilizes macromolecular material PTFE membrane (polytetrafluoroethylene) to form can effectually play waterproof ventilative effect, and the effect is showing, and latticed glass fiber yarn anti-tear layer that adds can effectual improvement non-woven fabrics tensile, bending strength, improves the toughness and the mechanical strength of non-woven fabrics, the life cycle of extension non-woven fabrics.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
In the figure, 1 is a first non-woven fabric layer, 2 is a wear-resistant layer, 3 is a waterproof layer, 4 is an anti-tearing layer, and 5 is a second non-woven fabric layer.
Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
As shown in fig. 1, a waterproof ventilative composite non-woven fabric of high strength, including first non-woven fabrics layer 1, second non-woven fabrics layer 5, wearing layer 2, waterproof layer 3 and anti-tear layer 4, wearing layer 2 sets up between first non-woven fabrics layer 1 and waterproof layer 3, anti-tear layer 4 sets up between waterproof layer 3 and second non-woven fabrics layer 5, waterproof layer 3 sets up between wearing layer 2 and anti-tear layer 4.
In a preferred embodiment of the invention, the waterproof layer 3 is a PTFE film (polytetrafluoroethylene).
In a preferred embodiment of the present invention, the tear-resistant layer 4 is a grid of fiberglass filaments.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
