YARN COMPOSED OF BICOMPONENT FILAMENTS TN THE FORM OF A SHEATH CORE STRUCTURE AND A METHOD OF PRODUCING THE SAME

Abstract Yarn composed of core-sheath filaments with or without further monocomponont filaments, wherein the core and the sheath of the core-sheath filaments have been produced by extruding spinnable polymers and at least almost dll the core-sheath filaments have a complete sheath, characterized in that of all the core-sheath filaments in the yarn, the proportion of core-sheath filaments P in % of which each core-sheath filament has (5 t 0.1 5) % of sheath content in the total volume of the particular core-sheath filament meets the following conditions at one and the same time: This yarn can be produced by a process wherein the core component is fed via a first spinneret plate to a second spinneret plate in a plurality of individual streams, and between the first and the second spinneret plate each individual stream of core component is ()nvolflllo.[ IJY lll~' c1!-1c)nl_11 L:UIllPUIIUIIL 'UU1IlY r~u onto .it, dnu the two components are conjointly spun, drawn and wound up, and at least in the area surrounding the individual !1 t rOilll\!\ u f curo C()lIIpullunL, the shettth component 18 subjected to a flow rAR i Rtt'tnc-:o. 1\ A\l i t.i1hl 0 flow ron i n- tance is provided by a wire mesh.
