Abstract

Filament à auto-texture et procédé de fabrication de ce filament. Le polymère de polyester est extrudé dans deux capillaires convergents à des vitesses différentes de façon à former à la sortie filière un courant combiné Les vitesses des courants et l'angle de convergence sont déterminés de façon que le premier des courants soit plus lent et se déplace sensiblement en ligne droite après le point de premier contact et d'union des courants, et que le second des courants soit plus rapide et forme des boucles sinueuses en va-et-vient entre les points successifs d'union avec le premier des courants Application au filage de fils à auto-texture.Self-texturing filament and method of making this filament. The polyester polymer is extruded through two converging capillaries at different speeds so as to form a combined stream at the die outlet.The speeds of the streams and the angle of convergence are determined so that the first of the streams is slower and moves substantially in a straight line after the point of first contact and union of the currents, and that the second of the currents be faster and form sinuous back and forth loops between the successive points of union with the first of the currents Application spinning of self-texturing yarns.
