Waterproof, breathable and moisture-permeable green recyclable fabric

Abstract

The invention relates to the technical field of recyclable fabrics, in particular to a waterproof, breathable and moisture-permeable green recyclable fabric, which comprises a surface layer, an air storage layer, a one-way passage layer and a heat preservation layer. The one-way passage layer is treated by adopting corresponding sorting equipment during recovery, and then is melted into yarns; thesorting equipment comprises a machine body, a screen belt, a cutting strip and a controller; due to the difference of the structures of convex covers in the one-way passage layer, two products with different components can be produced by directly crushing the convex covers and are mixed together to form impurities; therefore, an arranged steam box is matched with the cutting strip, water vapor inthe steam box permeates out through a capillary pipeline in the one-way passage layer, the convex covers at the end openings are jacked up and cut by the cutting strip above the screen belt, separation of the convex covers in the one-way passage layer is completed, and independent treatment of different material structures in the fabric is met, therefore the recycling effect of the waterproof, breathable and moisture-permeable green recyclable fabric is improved.

Description

technical field [0001] The invention relates to the technical field of recyclable fabrics, in particular to a waterproof, breathable and moisture-permeable green recyclable fabric. Background technique [0002] Waterproof, breathable and moisture-permeable fabric is a new type of textile fabric. Its composition is composed of polymer waterproof and breathable material and cloth. According to different product requirements, it can be made into two-layer composite or three-layer composite. It is widely used in clothing production; waterproof The air-permeable and moisture-permeable fabric not only enhances the air-tightness and water-tightness of the fabric, but also its unique vapor-permeable performance can quickly discharge the water vapor inside the structure, avoiding the breeding of mold in the structure, and solves the problems of ventilation, windproof, waterproof, and warmth; airtight quality The intact polyester fiber fabric can be processed twice, dried, crushed, me...

Problems solved by technology

[0003] In the prior art, there are also some technical solutions about waterproof, breathable and moisture-permeable green recyclable fabrics. For example, a Chinese patent with application number 2018216878912 discloses an energy-saving recyclable fabric, including a fabric center layer and a surface layer. The fabric and the inner layer fabric, the lower surface of the fabric center layer is fixedly equipped with an antibacterial layer, and the fabric center layer is composed of No. 1 fabric fiber and No. 2 fabric fiber, and the outer surface of the surface layer fabric is fixedly installed with a deodorization strip. And the inside of the surface fabric is provided with an elastic layer, the surface fabric is fixedly connected with the center layer of the fabric, a corrosion-resistant layer is arranged at the position where the inside of the surface fabric closely fits with the upper surface of the elastic layer, and the internal elasticity of the surface fabric The lower surface of the layer is fixedly installed with a toughness reinforcing layer; the energy-saving recyclable fabric in this technical solution is provided with a deodorizing strip, a waterproof layer and an insulating layer, which is convenient for absorbing odors to ensure that the fabric has no odor, and can effectively waterproof and avoid The fabric is wet, which can improve the heat preservation and cold resistance effect of the fabric, and bring better use prospects; however, the technical solution does not solve the fiber structure difference between the fabric layers in the process of fabric recycling, which is formed in the processed fabric mixture. Mutual impurity interference, it is difficult to effectively separate the functional structure of the fiber in its classification
