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.
This kind of fabric is usually used in a humid environment and does not have the function of antibacterial

Embodiment Construction

[0025] Specific embodiments of the present invention will be further described in detail below.

[0026] like figure 1 As shown, a kind of waterproof breathable bacteriostatic coating cloth of the present invention comprises base material cloth (1), and the single side of base material cloth (1) is printed with primer coating (2) and surface rubber coating (3) successively , the surface of the other side of the substrate cloth (1) is dot-printed with a bamboo charcoal powder layer (4).

[0027] The composition and weight ratio of the 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 surface active Agent, 0.7-0.8% defoamer.

[0028] 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% nonionic surfactant, 0.7% defoamer, 0.07% leveling agent, 4.0~5.5% white c...

Abstract

The invention discloses waterproof breathable bacteriostatic coated cloth, which is characterized in that: the cloth comprises substrate cloth; one side of the substrate cloth is orderly printed with a bottom glue coating and a surface glue coating; the bottom glue coating comprises the following components by weight: 76-80% of polyurethane, 0.9-2.2% of 5-50 um artificial zeolite powder, and 16-20% of DMF solvents; the surface glue coating comprises the following components by weight: 72-76% of polyurethane, 2.5-3.5% of 5-50 um artificial zeolite powder, 15-18% of DMF solvents, and 0.3-1.5% of anionic surfactants. The waterproof breathable bacteriostatic coated cloth of the invention combines microporous polyurethane with cloth by microporous film processing technology of thermoplastic polyurethane, has an additionally-disposed bamboo charcoal powder layer, and thus has the advantages of waterproofness, breathability, moisture permeability, bacteriostasis, wearing comfort, etc.

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 ...
