Abstract
The physical properties and dyeability of the nylon 6 fibers prepared by high speed spinning at take-up speed of 4,100∼5,600m/min were investigated. The strain decreased as the take-up speed was raised from 4,100m/min to 4,400m/min, but further increase of take-up speed could not decrease the strain. The stresses of the fibers spinned at various take-up speed did not make any noticeable differences. Birefringences, densities and crystallinities of the fibers increased with the take-up speed and then reached to a nearly maximum value at 5,300m/min. In DSC diagrams, the γ form of crystal became dominant at higher take-up speed.The dye uptakes of C. I. Acid Blue 113 on the fibers decreased a little with the increase of take-up speed.
