Problems solved by technology

The current laminated fabrics are mainly 20K / 20K. This laminated fabric already has good waterproof and moisture-permeable properties, but it still cannot achieve warmth, waterproof and moisture-permeable properties in some relatively extreme or harsh environments. Require
Research on the current lamination products found that in the lamination layer, the waterproof and moisture-permeable performance of the top rubber layer is high, but the waterproof and moisture-permeable performance of the bottom rubber layer is low. The moisture permeability of the fabric, the moisture permeability of the laminated fabric is 30-50% lower than that of the surface adhesive layer, so if a bonding layer can be provided that can improve the moisture permeability of the laminated fabric, the moisture permeability and waterproof performance of the laminated fabric can reach 40K / 20K, then it will have a huge impact on the status quo of laminating fabrics in the textile industry

Abstract

The invention discloses a fitting layer for improving the moisture permeability of a fitting fabric and a preparation method of the fitting layer. The fitting layer comprises a bottom adhesive layer and a surface adhesive layer, wherein the bottom adhesive layer comprises the following components by weight ratio: 100 parts of double-liquid type polyurethane resin, 10-50 parts of a bottom adhesive solvent, 1-10 parts of a polyisocyanate bridging agent, 0-5 parts of an accelerator, 5-30 parts of a one-liquid type polyurethane addition agent, 5-20 parts of a single-component moisture reactive polyurethane (PUR) addition agent and 0-5 parts of a softening agent and a tear-resistant agent; the surface adhesive layer comprises the following components by ratio: 100 parts of one-liquid type polyether polyurethane resin, 10-50 parts of a surface adhesive solvent, 0-2 parts of a release agent and 0-5 parts of a wax synthetic amorphous silica antisticking agent. By utilizing the fitting layer, the moisture-permeable and water-proof property of the fitting fabric reaches 40K / 20K.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a bonding layer used on a bonding fabric to improve the moisture permeability of the bonding material and a preparation method thereof. Background technique [0002] Fitting fabric refers to setting a fitting layer on the fabric, and using the performance of the fitting layer to endow the fabric layer with new functions. The general bonding layer includes a top rubber layer and a bottom rubber layer, and the bottom rubber layer must have sufficient adhesion to closely fit the top rubber layer and the fabric layer. Due to the addition of the fitting layer, the moisture permeability of the fitting fabric is an important parameter to measure the performance of the fitting fabric. The current laminated fabrics are mainly 20K / 20K. This laminated fabric already has good waterproof and moisture-permeable properties, but it still cannot achieve warmth, waterproof and moisture-permeable...
