NON-WOVEN FABRIC WIPE AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2023/245843

A1

A non-woven fabric wipe having a layered fiber web structure. A first layer, a second layer, a fourth layer, and a fifth layer of the non-woven fabric wipe are all melt-blown fiber webs mainly composed of melt-blown fibers; a third layer of the non-woven fabric wipe is a wood pulp fiber web mainly composed of wood pulp fibers; the melt-blown fibers in the melt-blown fiber webs of the second layer and the fourth layer are partially interwoven in the adjacent wood pulp fiber web of the third layer. Because the non-woven fabric wipe of the present invention is composed of five layers of fiber webs, when the melt-blown fiber webs of the second layer and the fourth layer are consolidated, the portions interwoven with the wood pulp fibers would consolidate the interwoven wood pulp fibers at the same time, thereby forming a protective web that prevents the wood pulp fibers from moving; moreover, the first layer, the second layer, the fourth layer, and the fifth layer of melt-blown fiber webs located on the outer sides of the third layer further protect the wood pulp fibers layer by layer, thereby preventing the occurrence of linting.
