Definition and working principle of waterproof fabric

Waterproof Fabric is a new textile fabric , its composition by the polymer waterproof breathable material (PTFE membrane ) plus composite fabrics made ​​of cloth . Waterproof breathable fabric main features are: waterproof, breathability , insulation, windproof and warm. Speaking from the production process , the technical requirements of waterproof breathable fabric waterproof fabric than the average much higher ; also from the quality point of view, waterproof and breathable fabric also has other waterproof fabrics do not have functional features. In strengthening the fabric waterproof breathable fabric tightness , water tightness , while its unique vapor permeability resistance, can be quickly discharged water vapor inside the structure , to avoid structural breed mold , and always keep the body dry , the perfect solution breathable and windproof , waterproof, warm and other issues, is a healthy and environmentally friendly new fabric .
Truly waterproof fabric long in a humid climate environment can withstand the pressure of water seepage , water seepage . Such as a long walk outdoors in wet and windy , kneeling or sitting on the wet ground , are not water seepage.
In the vapor state, the water particles are very small , according to the principle of capillary movement , can successfully penetrate into the capillary to the other side , so that the phenomenon occurs vapor permeability . When moisture condensation becomes drops , the particle becomes large , because the surface tension of water droplets ( water molecules to each other " counter pull " ) , the water molecules can not penetrate the drops smoothly from the other side , which is prevented water penetration occurs , the membrane with the water vapor permeability function.
