Expanded polytetrafluoroethylene-based thermal insulation moisture permeable garment material and preparation method thereof

Abstract

The invention discloses an expanded polytetrafluoroethylene-based thermal insulation moisture permeable garment material and a preparation method thereof. At least a fabric layer is connected on a microporous thin layer of the expanded polytetrafluoroethylene of the garment material through a bonding layer; the preparation method of the bonding layer being a chemical bonding layer comprises the steps that the bonding layer is applied on one side or two sides of the microporous thin layer of the expanded polytetrafluoroethylene and the fabric layer is composited on a chemical bonding layer, a multi-layer material is laminated through a roller, solvent is removed through drying and baking and solidification; and the preparation method of the bonding layer being a hot melting bonding layer comprises the steps that hot melting non-woven fabric is laid on one side or two sides of the microporous thin layer of the expanded polytetrafluoroethylene, a fabric layer is composited on the hot melting bonding layer, and air cooling shaping is carried out after laminated bonding through hot melt. By adopting the method, the expanded polytetrafluoroethylene-based thermal insulation breathable garment material has the characteristics of being soft, moisture permeable and beautiful, and keeping warm; and the fabric has breathable, moisture permeable and thermal insulation performances, thus eliminating uncomfortable wet feeling caused by wet gas.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a heat-preserving and moisture-permeable clothing fabric based on expanded polytetrafluoroethylene and a preparation method thereof. Background technique [0002] At present, the thermal insulation effect of underwear fabrics on the market is very poor, especially in spring, autumn and winter. The heat dissipation is fast, the temperature of the human body drops quickly, and people often feel cold and heavy; or wearing leather and artificial leather clothes, because the fabric clothes made of artificial leather are impermeable to moisture, and form a sealed artificial climate environment with the human body, people will feel cold. It is stuffy and humid, and wearing it for a long time will cause adverse reactions such as skin itching and allergies, which will affect healthy life; there are also thermal fabrics that use ultra-thin PVC plastic air-tight film in the lining to enhance ...

[0002] At present, the thermal insulation effect of underwear fabrics on the market is very poor, especially in spring, autumn and winter. The heat dissipation is fast, the temperature of the human body drops quickly, and people often feel cold and heavy; or wearing leather and artificial leather clothes, because the fabric clothes made of artificial leather are impermeable to moisture, and form a sealed artificial climate environment with the human body, people will feel cold. It is stuffy and humid, and wearing it for a long time will cause adverse reactions such as skin itching and allergies, which will affect healthy life; there are also thermal fabrics that use ultra-thin PVC plastic air-tight film in the lining to enhance wind resistance and prevent heat from leaking out, which is prone to static electricity and stuffiness The static electricity accelerates the dryness of the skin and the generation of dermatitis, and the strong feeling of stuffiness causes the sweat vapor of the human body to stick to the underwear and the surface of the human body, causing dermatitis and eczema; General effect
