Description
表４に示すとおり、実施例１〜１３の膜分離活性汚泥処理用半透膜用支持体は、延伸ポリエステル繊維と、バインダー繊維として未延伸ポリエステル繊維とガラス転移点が４０〜８０℃の共重合ポリエステルを鞘部とする芯鞘型ポリエステル複合繊維とを含有する不織布であり、層に含まれる繊維全体に対し、芯鞘型ポリエステル複合繊維の含有量が５〜５０質量％である第一表面層と、層に含まれる繊維全体に対し、芯鞘型ポリエステル複合繊維の含有量が５〜３０質量％である第二表面層とを有する多層不織布であることから、半透膜用支持体とフレーム材との接着強度及び第一表面層と第二表面層との接着強度に優れ、半透膜との接着性が良好であった。
As shown in Table 4 , the support for a semipermeable membrane for membrane separation activated sludge treatment of Examples 1 to 13 is a copolymer of stretched polyester fibers, unstretched polyester fibers as binder fibers, and a glass transition point of 40 to 80 ° C. 1st surface layer which is a nonwoven fabric containing the core-sheath-type polyester composite fiber which uses polyester as a sheath part, and content of a core-sheath-type polyester composite fiber is 5-50 mass% with respect to the whole fiber contained in a layer And a multi-layer nonwoven fabric having a second surface layer in which the content of the core-sheath polyester composite fiber is 5 to 30% by mass with respect to the entire fibers contained in the layer, the semipermeable membrane support and the frame The adhesive strength with the material and the adhesive strength between the first surface layer and the second surface layer were excellent, and the adhesiveness with the semipermeable membrane was good.
