PURPOSE:To obtain polyamide filament producible by cold drawing, having a set shrinkage percentage by hot water at the boiling point, comprising a polyamide resin composition consisting of a specific aromatic polyamide resin and an aliphatic polyamide resin. CONSTITUTION:Polyamide filament which comprises a polyamide resin composition consisting of (A) an aromatic polyamide resin obtained by polymerizing a polymer containing >=85wt% aromatic polyamide-forming component obtained from terephthalic acid and/or isophthalic acid and an aliphatic diamine such as hexamethylenediamine or ethylenediamine and (B) an aliphatic polyamide obtained by subjecting a three-membered or poly-membered lactam, a polymerizable omega-amino acid, dibasic acid, diamine, etc., to polycondensation, has >=20% shrinkage percentage of hot water at the boiling point and extremely excellent latent crimpiness and enables industrial production of conjugate yarn. |
