Mechanical Properties of Kanekalon, a Vinyl Chloride-Acrylonitrile Copolymer Fiber

Abstract

We seek to inquire experimentally into the mechanical properties of the single filaments of Kanekalon, a vinyl chloride-acrylonitrile copolymer fiber, at temperatures ranging from 10° to 90°C and humidities ranging from 30% to 90% R. H., and to compare these properties with the similar properties of the fibers dealt with in onr previous reports. ^[1_??_3]
The tensile properties of Kanekalon are also quantitatively represented by the seven tensile characteristics values-the first modulus of elasticity, yield point, yield elongation, elongation of the yielding part, secondary modulus of elasticity, elongation and tensile strength-used in our previous reports. ^[1_??_3]
The behaviors of creep and recovery from creep in Kanekalon nearly follow the general formulas of creep and recovery from creep given in the previous reports. ^[1_??_3]
Kanekalon is somewhat similar in their mechanical properties to terylene, but is poorer in tensile strength and rate of recovery from tensile elongation. Kanekalon is larger in the amount of relaxative elongation than terylene but shows a much lower rate of recovery from relaxative elongation.
The effect of temperature upon the mechanical properties of Kanekalon is as remarkable as on terylene. The effect of humidity upon the mechanical properties of Kanekalon, though slight, is slightly larger than on the similar properties of terylene.
