Polyurethane windproof air-permeable coat compounded textile fabric and preparation method thereof

Abstract

The invention discloses a polyurethane windproof air-permeable coat compounded textile fabric and a preparation method thereof. The preparation method comprises the following steps: on a transfer coat compounding device, compounding a solvent-type polyurethane slurry with phenylmethane, methylethylketone, porogen, a leveling agent, color paste and the like to form a surface layer coating working slurry; coating the surface layer coating working slurry onto a transfer carrier to form a polyurethane micropore structure layer; coating the solvent-type polyurethane binding resin, which is matched with the phenylmethane, methylethylketone, porogen, bridging agent, leveling agent and the like, on the surface layer to form a porous air-permeable binding layer; compounding textile cloth on the polyurethane coat resin, and curing by drying; separating from the transfer carrier to obtain a roll which is a semi-finished product; and compounding another kind of textile cloth on one side of the polyurethane coat in a dotted or reticular sizing mode on the compounding device to form the windproof air-permeable coat compounded textile fabric. The compounded fabric has the advantages of windproof property and air permeability.

Description

technical field [0001] The invention relates to a composite textile fabric with a polyurethane windproof and breathable coating and a manufacturing method thereof. Background technique [0002] With the progress of society, the vigorous development of outdoor sports, the rise of fitness sports, the improvement of people's living standards, and the needs of diversified living conditions, people not only have higher requirements for clothing styles, fabrics and other external aspects, Moreover, more and more attention is paid to some internal quality and internal functions. Textile fabrics with windproof and breathable properties have a wide demand in sports and leisure wear, morning exercise clothes, thermal underwear, windbreakers, etc. [0003] Some people used to punch holes in common plastic films (such as polyethylene, polypropylene, polyvinyl chloride) to produce some breathable films for the composite application of textile fabrics. But this approach has the following...

AI Technical Summary

Problems solved by technology

[0004] ① Due to the relatively large hole diameter, usually around 0.1mm, the windproof performance is poor. In the case of strong outdoor wind, it cannot block the intrusion of cold wind, and the warmth retention property is not good, which limits its application.

[0005] ②Plastic materials are non-hydrophilic materials, so they do not have the function of actively absorbing moisture and guiding sweat

[0007] ④The cold resistance of plastic film is not good, and it will become hard and brittle in cold conditions (below -20°C)

[0008] ⑤Plastic film cannot be degraded naturally and does not meet current environmental protection requirements
