BINDER FIBER AND SEPARATOR FOR ALKALINE CELL USING SAME

摘要

A binder fiber comprising a polyamide component in at least part of a surface thereof is prepared. The polyamide component contains a senini-aromatic polyamide at least having an aromatic ring unit and a C 3-7 alkane unit which may have a branched C 1-3 alkyl chain. In the binder fiber, the polyamide component may be (a) a semi-aromatic copolyamide having an aromatic ring unit, a C 3-7 alkane unit which may have a branched C 1-3 alkyl chain, and a C 8-12 alkane unit which may have a branched C 1-3 alkyl chain. The polyamide component may be (d) a combination of (b) a semi-aromatic polyamide and (c) a semi-aromatic polyamide, wherein the polyamide (b) has an aromatic ring unit and a C 3-7 alkane unit which may have a branched C 1-3 alkyl chain, and the polyamide (c) has an aromatic ring unit and a C 8-12 alkane unit which may have a branched C 1-3 alkyl chain.
