Embodiment 1

[0022] A method for manufacturing a high moisture-permeable and highly waterproof coated fabric, comprising the following steps:

[0023] ① Mix the following components by weight to form a fabric coating agent:

[0024] Polyurethane polymer 100 parts

[0025] Polar solvent butanone (or methyl isobutyl ketone, isopropanol) 50 parts

[0026] Non-polar solvent benzene (or toluene, xylene) 50 parts

[0027] Water repellant 4 parts

[0028] 9 parts of film former

[0029] Cross-linking agent 2 parts

[0030] slip agent 4 parts

[0031] 90 parts of water;

[0032] ②Apply the prepared fabric coating agent evenly on the base cloth to form a coating, and put the coating into an oven for drying treatment before the fabric coating agent is dry. The drying treatment temperature is 50-150°C (for example 50°C, 100°C, 150°C), the processing time is 30 seconds to 3 minutes (eg 30 seconds, 1 minute, 2.5 minutes, 3 minutes).

[0033] After step 2. drying treatment, also carry out post-d...

Abstract

This invention was a public high permeability high waterproof coating fabrics manufacturing methods, including polyurethane polymer, an organic solvent, allocation of water, as agent, crosslinking agents, other agents, water mixed into a fabric coating agents will be made of fabric coated with the coating in uniform as coating on the fabric, Fabric coating agent had dried occasion of the coating for drying processing steps. The invention manufactured coated fabric is not only an excellent waterproof and good moisture permeability but also has good rubbing sex and the feeling of fullness soft features. Product hydrostatic pressure 5000mm H2O over Al permeability to 8000g/m2 . 24hr above Tolerance washing and rubbing. Such coated fabric has broad prospects for sales, which can be used to produce rainwear, breathable, ski clothes, cool suits. Have greater economic and social benefits.

Description

Technical field: [0001] The present invention relates to a method for the manufacture of coated fabrics. Background technique: [0002] The existing waterproof and moisture-permeable coated fabric is made by uniformly coating the polyurethane polymer coating finishing agent on the fabric to form a layer of porous film on the surface of the fabric. [0003] Commonly used polymer coating finishing agents are solvent-based and water-emulsion-based. Solvent-based coating finishing agent has the characteristics of easy drying and tough and glossy coating film, but the pollution is serious and the cost is high. The water-emulsion coating agent uses water as the medium, which has the characteristics of no pollution to the environment and low cost. However, the water-emulsion coating agent takes a long time to dry and needs to be baked, and the process is more complicated. All in all, both types of coating agents have their advantages and disadvantages. [0004] As we all know, ...
