Problems solved by technology

The current laminated fabrics are mainly moisture-permeable and waterproof 20K / 20K. This laminated fabric already has good waterproof and moisture-permeable performance, but it still cannot achieve warmth, waterproof and breathable in some relatively extreme or harsh environments. wet multifaceted requirements
Research on the current bonding products found that, for the bonding layer, the waterproof and moisture-permeable performance of the surface rubber layer is generally high, but the waterproof and moisture-permeable performance of the primer layer is low. The main reason is that the primer layer needs to have sufficient adhesion. At the same time, it also needs to meet a certain feel. Therefore, after the primer layer is compounded on the fabric layer, the moisture permeability of the fabric is seriously reduced. The moisture permeability of the composite fabric is 30-50% lower than that of the surface rubber layer. Therefore, if it can provide A laminating layer that improves the moisture permeability of laminated fabrics, then has a huge impact on the status quo of laminated fabrics in the textile industry

Embodiment 1

[0033] A method for manufacturing a laminated fabric that improves moisture permeability. The laminated fabric includes a top rubber layer, a primer layer, and a fabric layer. The fabric layer is a fabric with a relatively high surface roughness. The manufacturing method includes:

[0034] a. Glue configuration: Mix 100 parts by weight of hydrophilic waterproof and moisture-permeable polyurethane resin with a solid content of 25-35%, 10 parts by weight of surface glue solvent, 1 part of anti-sticking agent, and 1 part of release agent Surface glue, the surface glue solvent is selected from DMF or toluene, and the anti-adhesive agent is selected from silicon derivatives, more preferably waxed silicon dioxide. The release agent is organic macromolecular silicon, and the hydrophilic waterproof and moisture-permeable polyurethane resin is one-component polyurethane resin. The viscosity of the surface glue is controlled at 500-3000cps;

[0035] The configuration process of the sur...

Embodiment 2

[0047]This embodiment is basically the same as Example 1, except that there are differences in the formulation. The proportion of the top glue in this embodiment is: 100 parts by weight of a hydrophilic waterproof and moisture-permeable polyurethane resin with a solid content of 25-35%, 50 parts by weight 10 parts of surface glue solvent, 5 parts of anti-adhesive agent, and 10 parts of release agent are mixed to configure the surface glue; the proportioning of primer is: 100 parts by weight of polyurethane resin with solid content of 40-60%, 50 parts of Peptizer, 10 parts by weight of bridging agent, 5 parts of bridging accelerator, 30 parts of hydrophilic waterproof and moisture-permeable polyurethane resin with a solid content of 25-35% in the surface glue, and 5 parts of PUR additives are mixed to configure the bottom Glue, the viscosity of the primer is controlled at 2000-8000cps. The addition of PUR additives in the primer can enhance the bonding strength of the primer, s...

Embodiment 3

[0060] This embodiment is basically the same as Example 1, except that there are differences in the formula. The proportion of the surface glue in this embodiment is: 100 parts by weight of a hydrophilic waterproof and moisture-permeable polyurethane resin with a solid content of 25-35%, 25 parts by weight 10 parts of surface glue solvent, 3 parts of anti-sticking agent, and 6 parts of release agent are mixed to configure the surface glue; the ratio of primer is: 100 parts by weight of polyurethane resin with a solid content of 40-60%, 25 parts of Peptizer, 5 parts by weight of bridging agent, 3 parts of bridging accelerator, 15 parts of hydrophilic waterproof and moisture-permeable polyurethane resin with a solid content of 25-35% in the surface glue, and 10 parts of PUR additives mixed to configure the bottom Glue, the viscosity of the primer is controlled at 2000-8000cps. The addition of PUR additives in the primer can enhance the bonding strength of the primer, so the prim...

Abstract

The invention discloses a method for manufacturing a bonded fabric with improved moisture permeability. The bonded fabric comprises a surface adhesive layer, a bottom adhesive layer and a fabric layer, and the method for manufacturing the bonded fabric comprises the following steps of: a, preparing an adhesive, namely preparing the bottom adhesive and the surface adhesive, wherein a primary adhesive of the surface adhesive is added in the bottom adhesive preparation, so that the moisture permeability can be improved; b, coating the surface adhesive on release paper, and drying the surface adhesive so as to form the surface adhesive layer; c, coating the bottom adhesive on the surface of the surface adhesive layer, and semi-drying the bottom adhesive; d, uncoiling the fabric layer and the release paper at a same speed, bonding the fabric layer and the bottom adhesive layer under a pressure of 4-6 kg / cm<2> so as to form a semi-finished product, and coiling the semi-finished product; and e, after the semi-finished product is cured, stripping away the release paper. According to the manufacturing method, the proportions of the surface adhesive and the bottom adhesive in the bonded fabric are improved, and hydrophilic waterproof and moisture-permeable polyurethane resin in the surface adhesive is added in the bottom adhesive, therefore, the moisture permeability of the bottom adhesive is improved, and then the moisture permeability of the bonded fabric can be improved, so that the waterproof and moisture-permeable properties of the bonded fabric break through 20K / 20K.

Description

technical field [0001] The invention relates to a manufacturing method of a laminated fabric, in particular to a manufacturing method capable of improving the moisture permeability of the laminated fabric. 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 moisture-permeable and waterproof 20K / 20K. This laminated fabric already has good waterproof and moisture-permeable performance, but it still cannot achieve warmth, waterproof and breathable ...
