Multifilament textile yarns with hollow section, method for making same, and textile surfaces obtained from said yarns |
摘要 |
The invention concerns a multifilament textile yarn whereof the filaments or staples have a hollow section, a method for making said hollow yarn, and textile surfaces obtained from said yarns. More particularly, it concerns a method for making multifilament yarns comprising hollow filaments obtained by melt-drawing of a polyamide composition having a yarn count less than 10 dtex for each staple and whereof the staples with hollow section have a central hollow surface representing at least 5% of the total surface in said staple transfer section. The invention is characterized in that the yarn has an USTER coefficient (U %) less than 3% and a number of staple with arc-shaped section less than 30% of the total number of staples with hollow section. The flat yarns, twisted and textured are used in particular for mixing textile surfaces, such as woven or knitted fabric.
