NON-WOVEN TABLECLOTH FORMED WITH VERY THIN ENDLESS THREADS

摘要

A non-woven fabric web of continuous filaments which may or may not be crimped, is made by direct controlled spinning and has a weight of 5-600 g/m<2>, formed after laying composite filaments that are separable in the longitudinal direction. The composite filaments have a titre of 0.3-10 dTex and are each made up of at least three elementary filaments made from at least two different materials, having between them at least one plane of separation or cleavage, each elementary filament having a titre of 0.005-2 dTex and the ratio between the cross sectional area of each elementary filament and the total cross sectional area of the unitary filament being 0.5- 90%.
