Abstract

The invention discloses a thermoplastic hydrophilic degradable waterproof moisture permeable film, which can be produced with the process comprising the steps that: polyester slices or polyamide slices and polyurethane slices are well mixed according to a weight ratio of 100:10, such that mixture slices are formed, wherein the polyester slices or polyamide slices are dehumidified and dried until a water content is below 0.02%; the mixture slices are placed in a high-temperature material cylinder, and are stirred and mixed under high temperature, such that a fused slice mixture is obtained; the fused slice mixture is stirred, and a nano-grade mixture and an anti-oxidant are sequentially added into the fused slice mixture, wherein the nano-grade mixture and the anti-oxidant are dehumidified and dried until the water contents are below 0.02%; the obtained fused slice mixture is subjected to a blow molding process, such that the degradable waterproof moisture permeable film is obtained. The degradable waterproof moisture permeable film provided by the invention has high-temperature resistance and high wear resistance. According to the invention, the function of the film surface is improved, and a produced fabric is provided with higher wearability and wider application scope.

Description

technical field

[0001] The invention relates to a thermoplastic hydrophilic degradable waterproof and moisture-permeable film, which belongs to the technical field of textile fabrics. Background technique

[0002] At present, the moisture-permeable membrane widely used in clothing composite materials is basically thermoplastic polyurethane (TPU). The thermoplastic polyurethane (TPU) film is molded through a thermoplastic polyurethane resin and calendered through a screw extruder. The nature of thermoplastic polyurethane (TPU) raw materials determines its poor wear resistance, and the temperature resistance of the membrane body itself is lower than 130°C, so it is not resistant to acid and alkali erosion.

[0003] This process solves the weakness of TPU's low temperature resistance and low wear resistance, improves the function of the membrane surface itself, and makes the fabric have higher wearability and use surface.

[0004] The existing one in the market that is closes...
