The physical properties and the dyeability of the nylon 6 fibers prepared by high speed spinning according to godet roller draw ratio form 1.1 to 1.6 were investigated. The strains of nylon 6 fibers were decreased against the increase of the godet roller draw ratio. The stresses of nylon 6 fibers were increased with the increase of the godet roller draw ratio.Birefringences, densities and crystallinities of the nylon 6 fibers were increased with the increase of godet roller draw ratio. In DSC diagrams, the γ form of crystal became dominant at higher godet roller draw ratio. The dye uptakes of C. I. Acid Blue 113 on the fibers were decreased against the increase of godet roller draw ratio.
