Wipe and manufacturing method thereof

Abstract

Disclosed is a wipe. Upper and lower layers of the wipe are melt-blown fiber webs, and an intermediate thereof is a wood pulp fiber web, wherein an adhesive is attached to the surfaces of the melt-blown fiber webs and to the interiors thereof that are adjacent to the surfaces, and the melt-blown fiber of the melt-blown fiber webs penetrates into the wood pulp fiber web. Also disclosed is a manufacturing method for the wipe. When the wipe is used, fluffiness and piling phenomena are prevented, such phenomena being caused by mutual disengagement of cementation between the melt-blown fibers under the action of external force since the surface melt-blown fibers are subject to multiple instances of friction.

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, wherein an adhesive is attached to surfaces of the melt-blows fiber webs and to interiors of the melt-blows fiber webs that are adjacent to the surfaces, and 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 melt-blown fiber webs contain one-component melt-blown fibers each having a high-melting-point resin at its surface, fibers each having a low-melting-point resin at its surface, or blend fibers of the two. 
     
     
         3 . The wipe of  claim 2 , wherein the high-melting-point resin and the low-melting-point resin have a melting-point difference therebetween of ≥20° C. 
     
     
         4 . The wipe of  claim 2 , wherein the fibers each having the low-melting-point resin at its surface are one-component melt-blown fibers, two-component melt-blown fibers, or a blend of the two. 
     
     
         5 . The wipe of  claim 4 , wherein the two-component melt-blown fibers are two-component skin-core melt-blown fibers, two-component segmented-pie melt-blown fibers, or two-component side-by-side melt-blown fibers. 
     
     
         6 . The wipe of  claim 1 , wherein the adhesive is hot-melt adhesive or solvent adhesive. 
     
     
         7 . The wipe of  claim 1 , wherein a weight percentage of the wood pulp fiber web in the wipe is greater than 50 wt %. 
     
     
         8 . The wipe of  claim 1 , wherein a weight percentage of the wood pulp fiber web in the wipe is 65 wt %-80 wt %. 
     
     
         9 . The wipe of  claim 1 , wherein the wood pulp fiber web contains a hot-melt adhesive substance. 
     
     
         10 . The wipe of  claim 9 , 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. 
     
     
         11 . A manufacturing method for the wipe of  claim 1 , comprising steps of:
 (1) opening and scattering wood pulp using an opening roller, and forming the wood pulp fiber web using a blowing nozzle in the presence of an auxiliary air stream;   (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, 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 in its middle;   (3) performing an adhesive spraying process using blowing nozzles in the presence of a high-pressure hot air flow to spray an adhesive on two side surfaces of the multi-layer fiber web having the melt-blown fiber webs at its two sides and having the wood pulp fiber web in its middle; and   (4) binding the fiber webs in the multi-layer fiber web after the adhesive spraying process 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 and having the adhesive attached to the surfaces of the melt-blown fiber webs and to the interiors of the melt-blows fiber webs that are adjacent to the surfaces.   
     
     
         12 . The manufacturing method of  claim 11 , in the step (2), heating and melting two thermoplastic resins having a melting-point difference therebetween of ≥20° C.; dispersing melt streams of the thermoplastic resins that have been extruded from the spinneret plates into the fiber bundles having a diameter of ≤10 μm using the high-temperature, high-speed hot air stream, in which the melt-blown fiber webs contain fibers each having a high-melting-point resin at its surface, fibers each having a low-melting-point resin at its surface, or blend fibers of the two. 
     
     
         13 . The manufacturing method of  claim 11 , wherein the spinneret plates have two-component spinneret orifices. 
     
     
         14 . The manufacturing method of  claim 13 , wherein the two-component spinneret orifices are arranged in a skin-core form, a segmented-pie form, or a side-by-side form. 
     
     
         15 . The manufacturing method of  claim 11 , wherein the heating device is a hot air oven, a hot rolling roller or a combination thereof. 
     
     
         16 . The manufacturing method of  claim 11 , in the step (1), mixing the wood pulp that has been opened and scattered by the opening roller with a hot-melt adhesive substance into a mixture, and blowing the mixture using the blowing nozzle in the presence of the auxiliary air stream to form the wood pulp fiber web containing the hot-melt adhesive substance.
