ことができない。Problems to be Solved by the Invention Conventional fake leathers such as the above-mentioned 7'C leather are broadly classified according to the degree of breathability. Therefore, even if moisture permeability is ensured, sufficient waterproofness cannot be obtained.

問題点を解決するだめの手段
多孔質ポリテトラフルオロエチレン膜と通気性樹脂層を
接着形成したことを特徴とする特許透湿性材料。``Structure of the Invention'' A patented moisture permeable material characterized by adhesively forming a porous polytetrafluoroethylene membrane and a breathable resin layer.

通気性が得られることから全体として透湿性が維持され

ルオロエチレン膜を保腹する。Porous W polytetrafluoroethylene membrane provides waterproof properties while ensuring moisture permeability.Breathable resin membranes maintain moisture permeability as a whole and maintain moisture permeability as a whole. A polytetrafluoroethylene membrane is used to preserve the abdomen.

しめ、しかも通気を阻止する。A hydrophilic resin layer can also be used in combination, and this hydrophilic resin layer prevents the porous polytetrafluoroethylene membrane from deteriorating its waterproof properties due to oil stains, surfactant contamination, etc., and also prevents ventilation. .

水性樹脂層は薄いものでよく、耐久性に優れた防水透湿
性材料となる。The hydrophilic resin layer has no air permeability, so if you try to obtain moisture permeability only with this hydrophilic resin layer as a waterproof and moisture permeable material, there is a limit to the coating thickness K, so you can achieve high durability while maintaining high moisture permeability. It is difficult to be used as a material. For this reason, a material in which an air-permeable side fat layer is bonded to a porous polytetrafluoroethylene membrane on which a hydrophilic resin layer is formed is thick and strong with this air-permeable resin layer, and air permeability is ensured. The resin layer may be thin, resulting in a waterproof and moisture-permeable material with excellent durability.
