Title:
SILKY, FINE-DENIER NON-WOVEN FABRIC AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/070981
Kind Code:
A1
Abstract:
A silky, fine-denier non-woven fabric, the silky, fine-denier non-woven fabric comprising an upper fine-denier fiber web composed of two-component melt-blown fibers having a fiber denier ≤ 1.0 denier, and a lower coarse-denier fiber web composed of fibers having a fiber denier of 2.0 to 12.0 denier. The upper fine-denier fiber web has an air permeability of 100-300m3/m2/min. The two-component melt-blown fiber uses a melt-blown sparse carding process to directly form fine-denier fibers. Furthermore, the fineness of the melt-blown fiber and the air permeability of the upper fine-denier fiber web is controlled by means of controlling a distance between adjacent spinneret holes and the pressure of a hot gas flow. This not only satisfies the condition of the fiber denier of the fine-denier fiber ≤ 1.0 denier, the formed fine-denier fiber web having a silky, delicate and smooth feel, it also effectively prevents the problems of difficult carding and processing of fine-denier fibers.
