Wipe and manufacturing method thereof

Abstract

A wipe comprises upper and lower melt-blown fiber webs and an intermediate wood pulp fiber web containing a hot-melt adhesive substance. Melt-blown fibers of the melt-blown fiber webs are interwoven in the wood pulp fiber web. A manufacturing method of a wipe can manufacture a water-absorbing wipe, effectively prevent the wipe from shedding fibers when in use, and effectively prevent agglomeration of short wood pulp fibers after the wipe has absorbed a liquid.

What is claimed is: 
     
         1 . A wipe, comprising upper and lower layers of melt-blown fiber webs and an intermediate layer of a wood pulp fiber web that contains a hot-melt adhesive substance, wherein melt-blown fibers of the melt-blown fiber webs are woven into the wood pulp fiber web. 
     
     
         2 . The wipe of  claim 1 , wherein the hot-melt adhesive substance is polyester fibers having a low-melting-point, ES short fibers, two-component spunbond long fibers or a blend thereof. 
     
     
         3 . The wipe of  claim 1  or  2 , wherein the hot-melt adhesive substance is present in the wood pulp fiber web in an amount of 1-15 g/m 2 . 
     
     
         4 . The wipe of  claim 1  or  2 , wherein the hot-melt adhesive substance is present in the wood pulp fiber web in an amount of 2-5 g/m 2 . 
     
     
         5 . The wipe of  claim 1 , wherein the melt-blown fibers are polyolefin fibers, polyester fibers, polyamide fibers, polyurethane fibers, polylactic acid fibers, or a blend thereof. 
     
     
         6 . The wipe of  claim 1 , wherein a weight percentage of the wood pulp fiber web in the wipe is greater than 50 wt %. 
     
     
         7 . The wipe of  claim 1 , wherein a weight percentage of the wood pulp fiber web in the wipe is 65 wt %-80 wt %. 
     
     
         8 . A manufacturing method for the wipe of  claim 1 , comprising steps of:
 (1) mixing wood pulp that has been opened and scattered by an opening roller with the hot-melt adhesive substance into a mixture, and blowing the mixture using a blowing nozzle in the presence of an auxiliary air stream to form the wood pulp fiber web containing the hot-melt adhesive substance;   (2) performing a melt blowing process involving heating and melting a thermoplastic resin; dispersing melt streams of the thermoplastic resin that have been extruded from spinneret plates into fiber bundles having a diameter of ≤10 μm using a high-temperature, high-speed hot air stream, thereby forming the melt-blown fiber webs in the presence of the hot air stream; and joining the melt-blown fiber webs with two side surfaces of the wood pulp fiber web containing the hot-melt adhesive substance, so as to form a multi-layer fiber web having the melt-blown fiber webs at its two sides and having the wood pulp fiber web containing the hot-melt adhesive substance in its middle; and   (3) binding the fiber webs in the multi-layer fiber web together using a heating device, so as to form the wipe having the upper and lower layers of the melt-blown fiber webs and having the intermediate layer of the wood pulp fiber web containing the hot-melt adhesive substance.   
     
     
         9 . The manufacturing method of  claim 8 , wherein the hot-melt adhesive substance is polyester fibers having a low-melting-point, ES short fibers, two-component spunbond long fibers or a blend thereof. 
     
     
         10 . The manufacturing method of  claim 8 , wherein the heating device is a hot air oven, a hot rolling roller or a combination thereof.
