Title:
SPUN-BONDED COMPOSITE WIPING NON-WOVEN FABRIC AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/000641
Kind Code:
A1
Abstract:
A spun-bonded composite wiping non-woven fabric (14), which is of a layered structure, and comprises an upper surface layer (12), an intermediate fiber layer (13), and a lower surface layer (12') in sequence, wherein at least one surface layer of the upper surface layer and the lower surface layer of the composite wiping non-woven fabric (14) is mainly composed of spun-bonded long fibers, the intermediate fiber layer (13) is mainly composed of viscose fibers, the weight of the intermediate layer fiber (13) accounts for 65% or more of the total weight of the composite wiping non-woven fabric, and there is a fiber interweaving interpenetrating area between adjacent layers of the upper surface layer and the lower surface layer and the intermediate fiber layer (13). By means of the non-woven fabric, when a viscose fiber with a longer fiber length is used as the intermediate fiber layer, the viscose fiber is not prone to unthreading from fiber pores of the upper surface layer and the lower surface layer, such that not only is the breaking strength of the composite wiping non-woven fabric increased, but also the phenomena of "powder loss and fluff loss" are prevented during use; and the spun-bonded long fibers in the surface layers (12, 12') increase the mechanical properties of the wiping non-woven fabric, which is more conducive to the application of the wiping non-woven fabric in the fields of makeup removal, facial cleaning, stain removal, etc.
