一、 PTFE微孔薄膜簡(jiǎn)介Introduction to PTFE Microporous Membrane
PTFE微孔薄膜由高結晶度的PTFE分散料，經(jīng)過(guò)擠壓、縱向拉伸、橫向拉伸，最終形成帶有立體三維結構的薄膜。其孔徑在0.02～5um之間，薄膜厚度在8～30um，孔隙率在80～97%之間。
PTFE micro-porous membrane is made up of high crystallinity PTFE fine powder and shaped into 3D structure through compressing, vertical and horizontal stretching. The membrane pore size is between 0.02~5μm, thickness is 8~30μm and porosity is between 80~97%.
金由iTEX高性能PTFE微孔薄膜特點(diǎn)
金由iTEX高性能PTFE微孔薄膜在生產(chǎn)之初，嚴格控制PTFE分散料品質(zhì)。配合18年P(guān)TFE微孔薄膜的生產(chǎn)經(jīng)驗，在生產(chǎn)過(guò)程中，對于細節精益求精。加上多處“獨到”的生產(chǎn)工藝，使金由iTEX高性能PTFE微孔薄膜具有高耐水壓力、高透濕性、高機械強度等性能。
Features of Jinyou iTEX PTFE membrane
The PTFE fine powder is controlled strictly before to be used as approved material.
And thanks to our 18-year experience and unique technology in producing PTFE membrane, we have consistently improved the product in every detail.
Therefore, iTex membrane is featured by high water resistance, high breathability and high durability.
高耐水壓力：在20次水洗以后，按美國ASTM D751-2006標準測定：C型達20,000mm耐水壓力。S型可達67,000mm耐水壓力，已達美國MIL-DTL-31011B水平（美國軍方標準），特別適用于軍、警、消防官兵服裝。
High Water Resistance
According to ASTMD7751-2006, water resistance for type C reaches 20,000mm H2O and Type S reaches up to 67,000mm H2O after 20 times washing, which meets the standard of US MIL-DTL-31011B. Therefore, it becomes ideal material to make uniforms for army, police and firefighting.
高透濕/透氣性：洗滌前透濕量（汗液形成的水蒸氣）按日本標準JISL099B1標準測試，C型達5000g/m2·24h以上,S型達7500g/m2·24h以上。
High breathability / Air Permeability
According to JISL099B1, the moisture breathability for Type C reaches over 5000g/m2·24h and Type S over 7500g/m2·24h before washing.
高耐用性：金由iTEX高性能PTFE微孔薄膜，由于在生產(chǎn)過(guò)程經(jīng)過(guò)的特殊的處理，使其具有極好的防油污性能。即使多次洗滌劑水洗后，仍具有高耐水壓優(yōu)點(diǎn)。解決了目前中國國內市場(chǎng)上一般PTFE面料，經(jīng)水洗后耐水壓急劇下降的難題，使用壽命大大延長(cháng)。
High Durability
Jinyou iTEX PTFE membrane has excellent oil and stain repellence due to special treatment. It also maintains high water resistance after being washed many times by detergent.
In contrast, water resistance from other companies’ membrane garment in Chinese market still drops dramatically after being washed.
So Jinyou iTEX PTFE membrane can greatly extend the service life and be a leader in the market.
