Porosity of PTFE clothing membrane
PTFE clothing film is made of polytetrafluoroethylene resin as raw material and is stretched in two directions through a special process Stretched microporous film. It is waterproof, breathable, windproof and warm. Widely used in cold-proof clothing, sportswear, fire protection, military, public security, medical care, biochemical protection and other special clothing as well as shoes, hats, gloves, sleeping bags. Tents etc.
In order to achieve waterproofing and windproofing, shoes, clothing, tents, and sleeping bags were first covered with waterproof glue on the fabric to achieve waterproofing purposes. Products made of this material and technology, It can withstand a certain amount of water pressure, but it is definitely not breathable and has poor waterproof and breathability. PU film is a material with good water pressure resistance. By combining the product fabric with it, it can achieve better waterproof stability. Its high-end products may have some moisture permeability, but the effect is not ideal.
The porosity of the polytetrafluoroethylene clothing membrane can reach 80%~90%, and after high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, and its surface is Filtration mechanism, easy dust removal, strong hydrophobicity, low surface energy, good non-adhesive ability, effectively removes dust accumulated on the surface, and can restore performance by washing with water or backflushing, greatly extending the service life, and the filtration efficiency can reach 99.999995%.
