DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a cleaning pouch and a manufacturing method thereof according to the present invention will be described in detail with reference to the accompanying drawings. For purposes of this specification, like reference numerals in the drawings denote like elements unless otherwise indicated.

FIG. 2 is a perspective view showing a cleaning cloth according to an embodiment of the present invention, FIG. 3 is a sectional view showing a cleaning cloth according to an embodiment of the present invention, wherein (a) FIG. 4 is a cross-sectional view showing a state in which foreign matter is collected into the embossed space of the cleaning cloth according to an embodiment of the present invention. FIG. 4 (b) is a cross- .

As shown in FIGS. 2 and 3, the cleaning cloth according to an embodiment of the present invention is formed by stacking a plurality of unit sheets formed with protrusions for spacing on one surface or both surfaces.

The unit sheet is made of a nonwoven fabric 100 and the nonwoven fabric 100 is made of 100% or more of any one selected from polypropylene (PP), polyethylene (PE), and polyester (PET) Or may be one produced by mixing at least one selected from among polypropylene (PP), polyethylene (PE), and polyester (PET) at a certain ratio.

Further, the nonwoven fabric 100 has a basis weight of 15 to 50 g / m < 2 > so as to be soft and to increase the generation of static electricity.

The spacing protrusions 110 formed on one surface or both surfaces of the nonwoven fabric 100 may be stacked in the form of facing each other or stacked in a zigzag form when the nonwoven fabric 100 is laminated with a plurality of layers.

Further, the gap maintaining protrusions 110 are preferably semi-spherical for friction between the cleaning surface and friction between the nonwoven fabrics.

In addition, a groove 120 may be formed in the nonwoven fabric 100 to accommodate a foreign substance 200 adsorbed on the nonwoven fabric between the spacing protrusions 110. Herein, the foreign substance 200 includes dust, hair, food waste, and dead skin that fall from the skin of a person.

As shown in FIG. 4, the foreign matter 200 on the cleaned surface is washed by the protrusions 110 of the nonwoven fabric 100 and is collected in the groove 120, so that the cleaned surface can be cleaned more cleanly, It is possible to prevent the foreign matter from separating from the cleaning surface and falling back to the cleaning surface.

In the present invention, embossing is carried out on both sides of the nonwoven fabric so as to have both the gap retaining protrusions 110 on the nonwoven fabric 100 and the grooves 120 for accommodating the foreign substances.

The spacing-maintaining protrusion 110 increases the mobility of the nonwoven fabric 100 stacked when an external force acts, increases the frictional force between the nonwoven fabrics 100, and the frictional force between the nonwoven fabric 100 generates static electricity

The reason why static electricity is generated is that ions or electrons move between two objects due to friction. Since the amount of electricity held by the object is proportional to the friction area, if the nonwoven fabric 100 is laminated with a plurality of layers, the friction area is increased and the amount of static electricity generated increases in proportion to the friction surface area.

In addition, the nonwoven fabric 100 made of a thermoplastic material has a high insulation property to prevent electricity from being transferred, and therefore, there is a tendency that the nonwoven fabric 100 keeps holding electricity. As a result, the amount of static electricity is increased.

As described above, according to the present invention, the nonwoven fabric 100 having the gap holding protrusions 110 is laminated in a plurality of layers to increase the friction area, friction between the nonwoven fabrics 100 laminated by the action of external force is generated, Thereby increasing the amount of static electricity generated and increasing the attraction force of the foreign matter.

Further, the outer surface of the nonwoven fabric 100, which is in contact with the cleaning surface, generates static electricity by friction with the cleaning surface, so that the attraction force of the foreign matter is further increased.

Since the external force acting here is an external force applied to the cleaning cloth during cleaning, the external force is constantly applied during the cleaning, so that the friction between the nonwoven fabric 100 is constantly generated and the amount of static electricity generated is kept constant. Therefore, even if the cleaning area is wide and the cleaning time is prolonged, the attraction force of the foreign matter does not deteriorate.

In addition, since foreign matter is contained and collected in the groove 120 of the nonwoven fabric, the cleaned surface can be more cleanly cleaned, the wider surface can be cleaned, and the foreign matter can be prevented from falling off the cleaning surface.

In addition, static electricity is generated constantly without coating the surface of the nonwoven fabric 100 with paraffin, so that the adsorption force can be maintained, and the bottom is not slippery after cleaning, thereby improving the stability.

In addition, the soft touch of the nonwoven fabric 100 and the protrusions 110 of the nonwoven fabric increase the slipperiness with respect to the cleaning surface, thereby improving convenience and efficiency of cleaning.

5 is a flowchart illustrating a method of manufacturing a cleaning cloth according to an embodiment of the present invention.

As shown in FIG. 5, a method of manufacturing a cleaning cloth includes the steps of preparing a flat nonwoven fabric 100, forming a spacing protrusion 110 on one or both surfaces of the nonwoven fabric 100, A step S30 of laminating the formed nonwoven fabric 100 into a plurality of layers, and a step S40 of fixing the rim of the laminated nonwoven fabrics 100.

First, in step S10, any one or two or more polymer materials selected from among polypropylene (PP), polyethylene (PE), and polyester (PET) are put into an extruder and melted. Then, the molten polymer material is spun on a distribution plate using a spin pump and a nozzle, and is solidified and drawn in the form of fibers. Then, the stretched polymer material is integrated in a web form on an integrated belt, bonded by heat bonding, and the thermally adhered polymer material is cut to a size of 15 to 50 g / m 2 in weight to prepare a flat nonwoven fabric 100.

The nonwoven fabric 100 prepared in this way has a high insulation property to prevent the electricity from being transmitted, which causes the static electricity to increase and the moisture absorption is not good, thereby helping to maintain the static electricity.

In step S20, a pair of embossing rollers having an embossed surface formed thereon are heated by a heater to 80 to 150 占 폚. Next, when the prepared nonwoven fabric 100 is inserted through the heated embossing rollers, the embossing is formed on both sides of the nonwoven fabric 100 passing through the pressure of the embossing roller.

The convex embossing formed on both sides of the nonwoven fabric 100 functions as a gap holding protrusion 110 and a groove 120 for receiving a foreign substance.

In step S30, a plurality of layers are formed by laminating the embossed nonwoven fabric 100 in two or three or more stages. At this time, the spacing protrusions 110 corresponding to each other by the lamination of the nonwoven fabric 100 may correspond to each other in a confronting manner or correspond to each other in a zigzag form.

In step S40, the edges of the stacked nonwoven fabrics 100 are stitched or bonded to complete the cleaning cloth.

Hereinafter, embodiments of the present invention will be described. However, the following examples serve to illustrate the present invention, and the present invention is not limited to the following examples.

(Example 1)

A nonwoven fabric of 20 cm in width × 10 cm in length × 5 mm in thickness was prepared using 100% of polypropylene (PP), and the embossing was formed on both sides of the nonwoven fabric to prepare a wipe.

(Example 2)

A nonwoven fabric having a width of 20 cm × 10 cm × 5 mm was produced by using 100% of polypropylene (PP), and the embossed embossing was formed on both sides of the nonwoven fabric, and then the embossed nonwoven fabric was laminated in two layers A cleaning cloth was prepared.

(Example 3)

A nonwoven fabric having a width of 20 cm and a length of 10 cm and a thickness of 5 mm was produced using 100% of polypropylene (PP), and embossing was carried out on both sides of the nonwoven fabric. Then, embossed nonwoven fabrics were laminated in three layers A cleaning cloth was prepared.

(Comparative Example 1)

A commercially available cleaning cloth having a size of 20 cm × 10 cm × 5 mm thick, which is made of a mixture of polyester and rayon and has no embossing, is used.

[Test Example]

To test the adsorption capacity of each cleaning cloth before the start of the test, each cleaning cloth was sprayed with 0.25 g of bread crumbs on the bottom surface of each of the four test areas to be tested, and each cleaning cloth was pressed with a force of 10 N for 30 seconds After rubbing on the floor, static electricity caused by friction was generated, and each piece of bread was wiped off once the bread crumbs were sprayed on the bottom of the area to be tested. Then, the final weight of the cleaning cloth with the crumb was measured, and the amount of the crumb absorbed was measured by subtracting the weight of the cleaning cloth from the final weight of the cleaning cloth. Table 1 shows the results of the adsorption test of bread crumbs.

 Cleaning cloth (g) Bread crumbs (g) Final weight of cleaning cloth (g) Amount of absorbed bread crumbs (g)  Adsorption percentage Example 1      6    0.25       6.12    0.12     48% Example 2     12    0.25      12.2    0.2     80% Example 3     18    0.25      18.25    0.25    100% Comparative Example 1      6    0.25       6.08    0.08     32%

As can be seen from Table 1, since Example 1 and Comparative Example 1 consist of one layer without the nonwoven fabric laminated, the bread crumbs were adsorbed only by the static electricity due to the friction between the cleaning cloth and the bottom surface. Example 3 shows that the adsorption performance was excellent due to adsorption of bread crumbs due to static electricity due to friction between the laminated nonwoven fabrics and static electricity due to friction between the bottom surfaces. Particularly, in Example 3, embossed nonwoven fabrics were laminated in three stages and exhibited an adsorption performance of 100%. During the application of an external force, static electricity was constantly generated due to friction between nonwoven fabrics. As a result, persistence of adsorption performance was maintained .

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims, And equivalents may be resorted to as falling within the scope of the invention.
