Abstract

The invention discloses a breathable and moisture-permeable coating. The breathable and moisture-permeable coating is prepared from 70-80 parts of polyurethane, 30-40 parts of polyvinyl chloride, 10-14 parts of polytetrafluoroethylene, 7-9 parts of a super absorbent polymer and 0.5-0.7 parts of wood pulp. Coated fabric comprises a base fabric and the breathable and moisture-permeable coating bonded to the base fabric; the base fabric is nylon fabric with the thread count of 100-136*80-96 count/10 cm; the thickness of the breathable and moisture-permeable coating is 0.1-0.5 mm. A preparation method of the coated fabric comprises the steps as follows: weaving nylon fabric; making the nylon fabric into large rolls; stacking the large rolls in a sodium bicarbonate environment; spreading and cleaning the large rolls; performing dyeing and hot tentering finish; mixing and stirring the breathable and moisture-permeable coating and water uniformly; spraying the mixture onto a plane; leaving the mixture to stand for solidification; bonding the breathable and moisture-permeable coating to the surface of the nylon fabric. The breathable and moisture-permeable coating has water-repellent property, moisture permeability, windproof property, thermal insulation, flexibility and high structural strength, and breathability, moisture permeability and waterproof property can be adjusted as required.

Description

technical field [0001] The invention relates to a coated cloth, in particular to an air-permeable and moisture-permeable coating, a coated cloth and a preparation method thereof. Background technique [0002] During outdoor activities, we often face severe weather such as rain, snow, and strong winds. At this time, clothing is required to have good waterproof, breathable and thermal insulation properties, and different solutions are required for different application fields. General waterproof and breathable fabrics have complex structures and manufacturing processes, and are expensive, so no specific solution can be given. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air-permeable and moisture-permeable coating, a coated cloth and a preparation method thereof, which are water-repellent, moisture-permeable, windproof, heat-retaining, flexible and structurally strong, and can be adjusted as required.
