3D DUSTING SHEET AND METHOD FOR MANUFACTURING THE SAME
A 3D dusting sheet comprising a base sheet, an electrostatic dusting sheet on the base sheet, and one or more linings disposed between the base sheet and the electrostatic dusting sheet, wherein the one or more linings bulge partially a main body of the electrostatic dusting sheet, such that a surface of the 3D dusting sheet becomes three-dimensional. Meanwhile, one or more three-dimensional spaces are formed on the surface of the 3D dusting sheet, whereby a large amount of dirt is gathered in the one or more three-dimensional spaces, and the effect of scraping and collecting the dust or dirt at the same time may be achieved by the 3D dusting sheet during cleaning.
1. Technical Field
The present invention relates to dusting sheets, and in particular to a 3D dusting sheet, which includes a multi-layer structure and a surface thereof is three-dimensional, and a method for manufacturing the same is also included in the present invention.
2. Prior Art
In view of the defects of the prior art, the present invention provides a 3D dusting sheet and a method for manufacturing the same, wherein the 3D dusting sheet comprises a structure in which one or more linings are disposed between the base sheet and the electrostatic dusting sheet, such that the surface of the 3D dusting sheet becomes three-dimensional, whereby a large amount of dirt is gathered in one or more three-dimensional spaces. Since the surface of the 3D dusting sheet is three-dimensional, the friction may be more concentrated during cleaning, and the effect of scraping and collecting the dust or dirt at the same time may be achieved. Regarding the method for manufacturing the same, the 3D dusting sheet is formed by partially re-incorporating the leftovers generated by trimming the fabrics during the process in-between the base sheet and the electrostatic dusting sheet through guiding means. In such a manner, a 3D dusting sheet with excellent capability can be manufactured economically.
In order to achieve the aforesaid objectives of the invention, a preferred embodiment of the present invention is provided herein. Please refer to
The linings (22) used in the embodiments of the present invention are leftover cloth straps generated in the manufacturing process of the electrostatic dusting sheet (21). As shown in
Next, please refer to

Next, please refer to
The process of manufacturing the 3D dusting sheet of the present invention includes:
-
- preparing in advance a base sheet (24) and an electrostatic dusting sheet (21) which are rolled up;
- guiding the base sheet (24) and the electrostatic dusting sheet (21) which are rolled up to be continuous to a guide pulley respectively;
- during the process, the electrostatic dusting sheet (21) is sent through a cutter wheel, whereby a plurality of triangular fins (7) are carved out on the electrostatic dusting sheet (21) by the cutter wheel and a plurality of storage spaces (9) are formed; meanwhile, the margins of the electrostatic dusting sheet (21) are trimmed by the cutter wheel and the trimmed-off leftovers are obtained;
- re-incorporating the leftovers of the electrostatic dusting sheet (21) trimmed to be straps into the process by guiding means, so as to employ the leftovers as the linings (22) and overlie the linings on the electrostatic dusting sheet (21) in any required shape according to the arrangement of the linings (22) mentioned by the above embodiments;
- combining the base sheet (24), the electrostatic dusting sheet (21), and the linings (22) formed by the leftovers by fusion to form continuous 3D dusting sheet;
- trimming the prepared continuous 3D dusting sheet by cutting means to obtain a 3D dusting sheet with a desired length.
The aforementioned process utilizes fusion means to combine the base sheet (24), the electrostatic dusting sheet (21), and the linings (22). However, ultrasonic spot welding may be utilized to weld the each layer of material by spot for reducing the power consumption of welding apparatus. Undoubtedly, it is also possible to secure each layer of material and the linings by physical stitching means.
It is preferred that the 3D dusting sheet of the present invention be used with a mop having a flat panel.
As for the electrostatic dusting sheet (21), it may be made of 100% of chemical fiber so as to cause electrostatic phenomenon spontaneously under friction. In addition, the electrostatic dusting sheet (21) may be imbued with negative voltage such that the body or fibers of the electrostatic dusting sheet carry negative electrons to provide the electrostatic attraction effect.
The above embodiments are for better understanding of the present invention, and the scope of the invention is defined by the appended claims.
