Abstract
The invention relates to an ultrathin leisure fabric with windproof and breathable functions and a manufacturing method of the ultrathin leisure fabric with the windproof and breathable functions. The method includes the steps that material is mixed; a blank is manufactured; pushing and pressing are performed; calendaring is performed; ungreasing treatment is performed; longitudinal stretching is performed; bi-directional stretching is performed in an arc shape; after transverse stretching, agglomeration and solidification are performed; films are attached through a release paper transferring method; the ultrathin leisure fabric is formed through glue compositing on textile fabric. The ultrathin leisure fabric manufactured through the steps is used for the fields of down garments, leisure sportswear, shoemaking and others, the thickness of the teflon microporous film is 2 micrometers-5 micrometers, the pore diameter is 0.5 micrometer-2 micrometers, and the porosity is over 80%. The ultrathin leisure fabric has the multiple functions of being light in weight, windproof, waterproof, breathable and resistant to ultraviolet and corrosion, discharging sweat and keeping warm and is suitable for various products, which are made of functional materials, for kinds of sports, leisure and women and children.
Description
Technical field: [0001] The invention relates to the field of fabrics, in particular to an ultra-thin casual fabric with windproof and breathable functions and a preparation method thereof. Background technique: [0002] Expanded PTFE microporous membrane is a porous material formed by multi-directional stretching (i.e. expansion treatment), calendering, heat treatment and other processes. It is a flexible and elastic microporous material with high porosity and pore size distribution. Uniform membrane with sterilization and filtration functions. The surface of the material is smooth and soft. However, under the scanning electron microscope, it can be seen that there are a large number of micropores of 0.4 μm to 1 μm inside the material, and its porosity can account for more than 80%. This material has the following characteristics: non-hazardous, light in weight, corrosion-resistant, resistant to environmental changes, overcomes the cold flow (creep) of pure PTFE sealing mat...
