[0002] Composite fabric is a new type of material, including one or more layers of textile materials, non-woven materials and other functional materials, which are bonded and bonded. Compared with conventional fabrics, it has many excellent properties. PE composite fabrics A kind of fabric obtained by preparing a functional layer from polyethylene and bonding it with other materials. The polyethylene film made by biaxial stretching, due to the properties of polyethylene itself, the distribution, number, and size of pores on the surface , the material of the composite fabric, etc. will affect the air permeability of the composite fabric, and the realization of the air permeability of some existing PE composite fabrics often leads to the loss of water resistance, and the hardness is high, and the comfort is relatively low.

Abstract

The invention discloses a highly air-permeable PE composite fabric and a preparation method thereof, comprising a functional layer and a lining. The fabric is prepared by compounding the functional layer and the lining. Olefin membranes include the following components: low density polyethylene, ultra-high molecular weight polyethylene, and high density polyethylene. In the present invention, through the arrangement of the functional layer in the composite fabric, the wrapping layer is wrapped and attached to the surface of the polyolefin diaphragm layer and occupies the pores on the surface of the polyolefin diaphragm. A number of micropores are formed in the lining, which increases the porosity of the wrapping layer, improves the air permeability of the functional layer, and ensures the waterproof performance of the functional layer. Water resistance, anti-ultraviolet, anti-friction, anti-aging and other properties, realize the protective performance and high air permeability of the composite fabric, suitable for wide promotion and use.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a high air permeability PE composite fabric and a preparation method thereof. Background technique [0002] Composite fabric is a new type of material, including one or more layers of textile materials, non-woven materials and other functional materials, and is made by bonding. Compared with conventional fabrics, it has a variety of excellent properties. PE composite fabrics A fabric obtained by preparing a functional layer with polyethylene as a raw material and bonding with other materials. The polyethylene film made by biaxial stretching has the characteristics of polyethylene itself, the distribution, number and pore size of pores on the surface. , the material of the composite fabric will affect the air permeability of the composite fabric, and the realization of some existing PE composite fabrics often leads to the loss of water resistance, and the hardness is high and the ...
