POLYMERIC FILAMENT HAVING AT LEAST ONE LONGITUDINAL ETOFFE CHANNEL COMPRISING THESE FILAMENTS, ARTICLE FORMED THEREFROM, AND METHOD OF MAKING SAID FILAMENT

摘要

Polymeric filament (1,6) comprising on at least a portion of its length at least one longitudinal channel (7,8,9,10,16), solid or empty, forming, in a cross section (VA, VB, VC) said filament (1,6), an externally surface opening orifice or an internal closed orifice (16a), characterized in that the disposition of said orifice (16a) differs from a cross section (VA, VB, VC) to the other along the length of said portion, whereby the longitudinal channel (7,8,9,10,16) has a longitudinal disposition which is not the longitudinal direction of said filament.In a variant, the filament (1,6) is rectilinear and comprises over its entire length at least one continuous longitudinal channel (7,8,9,10,16) having a continuous spiral disposition in the same direction along the entire length of the filament (1,6). also relates to a textile fabric, in woven, knitted or non-woven form, comprising said filaments (1,6) from which it is made a textile article, especially for the practice of sport, and a method of manufacturing said filament (1,6).
