TPU belongs to imperforate hydrophilic membrane, as the membrane itself has no aperture, the waterproof effect is good,also keep fabric windproof and warm. permeability achieve through its hydrophilic feature, rely on diversity between inside garment and outside garment, make steam transfer from high pressure position to low pressure position, thus achieve permeability function. main function is as following: waterproof, permeability, breathable, insulation, windproof, warm. This fabric can eliminate inside steam quickly at the same time that it enhance the fabric impermeability and water proofness.
