Polyester cationic

Cationic dyeable polyester, aha kemịkal: polybutylene terephthalate (polyester na-agbanwe); Aha Bekee: cationic polyester a na-esiji; abbreviation: PBT, nke a na-ejikwa na CD ụlọ ọrụ mmepụta ihe. Cationic polyester bụ nke polyester denaturered/gbanwetụrụ ma enwere ike iji akwa cationic siji ya na 110 C.
