PURPOSE:The titled filament having specific intrinsic viscosity, specified titanium oxide content, specific amount of carboxyl residue, high toughness, high modulus, improved resistance to fibrillation and high fastness to wet friction and slightly slackening. CONSTITUTION:The titled polyester monofilament having 0.7-1.2 intrinsic viscosity, <=0.1wt% titanium oxide, <=25<eq>/10<6>g carboxyl residue amount and preferably 9-20 denier fineness. The polyester is preferably polyethylene terephthalate. |
