    摘要： A filtering medium which is unchanged in the maximum pore size even when heating sterilization, high temperature filtration, etc. are carried out, yet has a high tensile strength, can be processed into pleat-form and also is applied to high precision filtration, is provided,
       which filtering medium is a product having a nonwoven fabric composed of 20 to 80% by weight of lower melting point microfine fibers and 80 to 20% by weight of higher melting point microfine fibers having a melting point higher by 10°C or higher than that of the lower melting point microfine fibers, the respective fibers being hot-melt-adhered to one another through the lower melting point microfine fibers, hot-melt-adhered to a hot-melt-adhesive net, and having a maximum pore size of 120 µm.

    摘要翻译： 即使进行加热灭菌，高温过滤等时，最大孔径也不变化，而且拉伸强度高，可以加工成褶状，也适用于高精度过滤。 该过滤介质是具有由20〜80重量％的低熔点微细纤维构成的无纺布和80〜20重量％的熔点高于10℃以上的高熔点微细纤维的产品 比较低熔点的微细纤维的纤维通过较低熔点的超细纤维彼此热熔粘合，热熔粘附到热熔胶网上，并具有最大孔径 120亩。
