氨酯膜，其通过KS K 3054测量的100％模量在约2.5至3.5的范围内， 通过ISO 0811测量的约13,000至18,000mmH_2O的范围和通过氯化钙测试（JIS L 1099A-1方法）测量的在大约15,000至20,000g / m 2·24小时范围内的水蒸汽的透水性。 疏水性多孔型聚氨酯软质膜通过以下步骤制造：（i）通过将聚氨酯树脂组合物涂布在剥离纸上形成聚氨酯膜; （ii）使形成在表面上的聚氨酯膜的剥离纸通过凝固物凝固聚氨酯膜; 和（iii）将分离纸与凝结的聚氨酯膜分离。 这里的剥离纸是剥离衬里织物。 本发明具有以下效果：防止由于汗，雪，雨等而使表面膨胀而导致美观或触觉感觉降低; 在保持水压的同时提高水蒸汽的渗透性; 提供柔软的触感（柔软触感），以及优异的耐洗涤耐久性。 因此，本发明可以有效地用作制造运动服装，工业服装，军服或医疗服装的材料。
The minority of the present invention is a conformal polyurethane flexible membrane and fine pores are formed non-uniformly composed of a polyurethane film is not swollen by water, a 100% modulus of 2.5 to 3.5 measured by the KS K 3054 method, ISO 0811 how a water pressure is 13,000 ~ and 18,000㎜H
2 O, which is a water vapor transmission rate is 15,000 ~ 20,000g / ㎡ · 24 time measured by JIS L 1099 a-1 calcium chloride method to measure.
The small number of the polyurethane conformal step of coating a polyurethane resin composition on a flexible film (ⅰ) release liner film is formed of polyurethane; (Ⅱ) a step of solidifying the polyurethane film was passed through a poly urethane film having a release paper into a high response; And (ⅲ) separating the release paper from the coagulated polyurethane film process; the minority through the preparation of conformal polyurethane film is produced using a fabric with the release paper.
The invention sweat, snow, is the swelling surface by rain and can aesthetics are dropped or can touch are effective in preventing the deterioration problem, while maintaining a water pressure resistance significantly improve the moisture permeability, soft feel (soft touch) and excellent washing durability can also be granted.
Thus, the present invention is useful in sports clothing materials, industrial clothing materials, clothing materials, or taking military medical materials, etc..
