The development of modern science and technology is becoming more mature, and many membrane materials have become available. Among them, the Polytetrafluoroethylene microporous membrane with lower resistance and higher efficiency has been continuously developed and put into use.
The use of ePTFE membrane in outdoor garments: The diameter of the micropores of the clothing membrane varies from 0.1 to 0.5 microns, while the diameter of water vapor molecules is 0.0004 microns. The smallest diameter of light mist in rainwater is The diameter is 20 microns, and the diameter of drizzle is already as high as 400 microns. The pore diameter is between water vapor and rainwater. The micropore diameter is smaller than the smallest light mist among water molecules, and much larger than the diameter of water vapor molecules. It can allow water vapor to pass through but water droplets cannot. By using this microporous structure, excellent waterproof and breathable functions can be achieved, so it is an excellent waterproof and breathable material.
Polytetrafluoroethylene microporous membrane is a three-dimensional mesh structure with no through holes. Open porosity and pore size distribution are important indicators for measuring membranes. The porosity of Teflon membrane is generally between 80% and 95%. A high opening rate will increase ventilation; a concentrated pore size distribution indicates that the membrane pore size is uniform. With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
