Abstract

Improvements in zipper closures, of stable dimensions of polyester single strands, characterized in that the intrinsic viscosity J of the single strand is 0.80 to 1.07, the orientation angle of the crystallites is within the single strand between 17º and 26º, because there is a numerical relationship between the intrinsic viscosity J and the orientation angle of the crystallites, orientation angle = 8 (4 x J - 1) the equation being considered fulfilled, when the measured angle does not exceed the value previously given by the equation, in excess or defect, by more than 2º, and because the average width of the crystallites, in the transverse direction of the wire, amounts to 80 to 200 Å and the mean oscillation of the size of the crystallites in the direction of the wire, indicated numerically by the width of the average value of the reflection of the small angle of X-rays, is a maximum of 0.40 °.
