Problems solved by technology

Although PTFE fabric has good waterproof and moisture permeability, it generally has poor hand feeling, poor washing fastness and wind resistance, especially it is not easy to be naturally degraded, and the burning temperature is high, so it will cause damage to the environment.

Embodiment Construction

[0020] Specific embodiments of the present invention will be further described in detail below.

[0021] Such as figure 1 As shown, a waterproof and breathable coated cloth of the present invention includes a base material cloth 1, and one side of the base material cloth 1 is sequentially printed with a primer coat 2 and a top coat 3.

[0022] The composition and weight ratio of primer coating 2 are: 76-80% polyurethane, 0.9-2.2% 5-50um artificial zeolite powder, 16-20% DMF solvent, 0.5-2.0% anionic surfactant, 0.7~0.8% defoamer.

[0023] The composition and weight ratio of the top coat 3 are: 72-76% polyurethane, 2.5-3.5% 5-50um artificial zeolite powder, 15-18% DMF (dimethylformamide) solvent, 0.3-1.5 % anionic surfactant, 0.7-2% non-ionic surfactant, 0.7% defoamer, 0.07% leveling agent, 4.0-5.5% white color paste.

[0024] The process of making the waterproof breathable coated cloth of the present invention comprises:

[0025] Glue adjustment: Stir the above base glue a...

Abstract

The invention discloses waterproof ventilated coated cloth. The waterproof ventilated coated cloth is characterized by comprising substrate cloth; a primer coating and a surface adhesive coating are printed on a single surface of the substrate cloth sequentially; the primer coating comprises the following components in percentage by weight: 76 to 80 percent of polyurethane, 0.9 to 2.2 percent of artificial zeolite powder with the grain size of 5 to 50 micrometers, and 16 to 20 percent of dimethy formamide (DMF) solvent; and the surface adhesive coating comprises the following components in percentage by weight: 72 to 76 percent of polyurethane, 2.5 to 3.5 percent of artificial zeolite powder with the grain size of 5 to 50 micrometers, 15 to 18 percent of DMF solvent and 0.3 to 1.5 percent of anionic surfactant. In the waterproof ventilated coated cloth, the polyurethane and the cloth are combined by a thermoplastic polyurethane film processing technology. A polyurethane film has no pores, so that the polyurethane film has high wind resistance and waterproofness; meanwhile, the polyurethane film has high hydrophilcity, and realizes the moisture-permeable function by using pressure difference of internal and external water vapor, and the polyurethane can be easily degraded naturally, and is soft, so that the cloth has the advantages of environment-friendliness and comfort in wearing and the like.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a waterproof and breathable cloth. Background technique [0002] Usually, in the case of fabrics with high water resistance, the two properties of breathability and moisture permeability are contrary to each other, and only one of them can be selected. Non-breathable and moisture-permeable fabrics cannot keep human skin dry, that is, it is easy to breed mold, and it does not keep warm. There are many studies on waterproof, moisture-permeable and breathable fabrics, and there are currently three solutions: high-density fabrics treated with water repellency, laminated fabrics and coated fabrics. Among these three methods, the cost of coated fabric is low, and the production process is simple, so it is widely used. Coated fabrics are usually made of a polymer waterproof and breathable material (PTFE membrane) plus cloth. Although PTFE fabrics have good waterproof and moisture ...
