Document Type and Number:
WIPO Patent Application WO/2020/147228
Kind Code:
A1
Abstract:
Provided are a wear-resistant wipe (16, 26, 37) and a manufacturing method therefor. The wear-resistant wipe (16, 26, 37) has upper and lower layers of melt-blown fiber webs (13, 14, 23, 24, 34, 35), and an intermediate layer of a wood pulp fiber web (12, 22, 33), wherein the melt-blown fiber web (13, 14, 23, 24, 34, 35) contains melt-blown fibers with fiber surfaces of a high-melting-point resin and melt-blown fibers with fiber surfaces containing a low-melting-point resin, the difference between the melting point of the low melting point resin and the melting point of the high melting point resin is greater than or equal to 20°C, and the percentage of the melt-blown fibers, with the fiber surfaces containing the low-melting-point resin, in the total fibers of the melt-blown fiber web (13, 14, 23, 24, 34, 35) is greater than 5%; and the melt-blown fibers of the melt-blown fiber web (13, 14, 23, 24, 34, 35) are woven into the wood pulp fiber web (12, 22, 33).
