Preparation of Nylon 56(PA 56) Fibers and its Mechanical Properties and Dyeing Behavior
Nylon 56(PA 56) and nylon 6(PA 6) fibers were prepared using the melt spinning method.The effects of drawing conditions on mechanical properties, moisture absorption, dyeing behavior were investigated by means of tensile testing measurements, moisture absorption test, as well as color strength measurements.It was found that the tenacity, Youngs modulus were significantly increased, while the elongation at break decreased as the draw ratio increased.The improvement in mechanical properties may be attributed to the increase of orientation along the fiber axis and thecrystallinity.Nylon 56 fibers showed a little lower mechanical properties and much higher moisture regain than nylon 6 fibers at different draw ratios.This can be attributed to the amide groupcontent in the polymer backbone, which yields higher moisture regain in nylon 56 fibers than nylon 6 fibers.The dyeing behaviors of nylon 56 fiber, in terms of dyebath exhaustion, color strength, and wash fastness are similar as those of nylon 6.Those results indicated that nylon 56 is a competitive novel fiber for textile material.
