Masters Theses
A comprehensive study of the structure development during high speed melt spinning of nylon-6 was performed. The major emphasis of the research was on the effect of molecular weight in the structure development of high speed melt spun nylon-6 filaments. The various measurements done on the filaments to determine their morphology included diameter, tensions in spin-line, density as well as x-ray diffraction and birefringence measurements. The effects of mass throughputs were also studied. Tensile properties of conditioned fibers were measured and related to the spinning variables and molecular weight.
The spin-line stresses measured increased rapidly with take-up velocity and molecular …
