Dust removal cloth structure

Abstract

This invention provides a dust removal cloth structure that achieves both scraping and adsorption functions in a single-layer material while maintaining structural integrity. [Solution] The dust removal cloth structure consists of a single layer of nonwoven fabric, with multiple three-dimensional fluffy layer regions 2 and multiple grid-like layer regions 1 alternately arranged on the surface. The grid-like layer regions 1 and the three-dimensional fluffy layer regions 2 are integrally molded by density rearrangement of the fibers of the same single layer of nonwoven fabric. The three-dimensional fluffy layer regions 2 perform electrostatic adsorption, while the grid-like layer regions 1 utilize the difference in physical thickness to scrape and guide dust. The differences in the multi-region structure within the single layer generate multi-directional friction and airflow dust guidance effects, improving cleaning efficiency and extending lifespan.

Description

Technical Field

[0001] The present invention relates to a dust removal cloth structure, and particularly to a multi-region dust removal article formed by differences in the physical structure of a single-layer non-woven fabric.

Background Art

[0002] Conventional dust removal cloths are often manufactured by multi-layer lamination or simple heat pressing. The multi-layer structure is not only costly and has poor air permeability, but also easily causes peeling at the adhesion interface or pressing interface between materials of different layers. Moreover, in simple heat pressing, the fibers become overly dense, and the space for adsorbing dust is easily lost. It is an important industrial issue to achieve both the "scraping" function and the "adsorption" function in a single-layer material while maintaining structural integrity.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The main object of the present invention is to provide a dust removal cloth structure that achieves a multi-functional cleaning effect due to differences in the structure of each region within a single-layer material.

Means for Solving the Problems

[0004] To achieve the above object, the technical means adopted by the present invention are as follows. That is, a dust removal cloth structure composed of a single-layer non-woven fabric body, wherein the surface of the non-woven fabric body is divided into a plurality of grid-like layer regions (1) and a plurality of three-dimensional hair-like layer regions (2).

[0005] The grid-like layer regions (1) and the three-dimensional hair-like layer regions (2) are arranged alternately. The fiber arrangement of the grid-like layer regions (1) is denser than that of the three-dimensional hair-like layer regions (2), and the thickness of the grid-like layer regions (1) is thinner than that of the three-dimensional hair-like layer regions (2).

[0006] The technical feature of this invention is that the grid-like layer region (1) and the plurality of three-dimensional fluffy layer regions (2) are a continuous, integrated structure formed by the rearrangement of the fibers of the same single layer of nonwoven fabric. [Effects of the Invention]

[0007] According to this invention, the difference in physical density and thickness within the single-layer fabric allows for the simultaneous provision of two functions during wiping: "scraping off large particles" and "adsorption of fine dust." Furthermore, when the lattice-like layer region (1) functions as a support frame (support member), there is no heterogeneous bonding interface between it and the fuzzy region (2), thus preventing the fuzzy region (2) from falling off or becoming flattened due to frequent extrusion or pulling. [Brief explanation of the drawing]

[0008] [Figure 1] This is a schematic diagram showing the surface of the dust removal cloth structure of the present invention. [Figure 2] This is a localized enlarged cross-sectional view of the dust removal cloth structure of the present invention. [Figure 3] This is an enlarged view showing further details of the dust removal cloth structure of the present invention. [Modes for carrying out the invention]

[0009] As shown in Figures 1, 2, and 3, the dust removal cloth structure of the present invention is composed of a single layer of nonwoven fabric. The nonwoven fabric may be composed of polyester fibers (PET), polyethylene fibers (PE), polypropylene fibers (PP), or composite fibers thereof.

[0010] The aforementioned lattice-like layer region (1) is characterized in that its fibers exhibit a cross-knotted structure, forming a lattice-like texture with physical rigidity. This region has a high fiber density, forming a strong structural support. This structure provides the mechanical force needed to scrape away dust from the ground during the cleaning process.

[0011] The three-dimensional fuzzy layer region (2) is characterized in that its fibers are arranged in a bulky (loose) manner and it has a plurality of fuzzy protrusions that extend in a direction away from the central surface of the nonwoven fabric. The thickness of the three-dimensional fluffy layer region (2) is 2 to 10 times the thickness of the grid-like layer region (1), and this difference in thickness creates fine airflow channels when the cloth comes into contact with the ground.

[0012] Since the lattice-like layer region (1) and the three-dimensional fluffy layer region (2) are an integrated structure directly composed of the same single-layer nonwoven fabric fibers, there is continuity between the two regions through interwoven fibers, and it is not laminated by adhesive or the like. This integrally molded structure allows the dense structure of the lattice-like layer region (1) to function as support for the entire framework, and excellent stress transfer is formed between it and the three-dimensional fluffy layer region (2). As a result, the three-dimensional shape and adsorption height of the three-dimensional fluffy layer region (2) are maintained even after repeated use.

[0013] During cleaning operations, the grid-like layer region (1) first comes into contact with the ground to scrape and collect dust, guiding relatively large particles of dust into the adjacent three-dimensional fuzzy layer region (2). Subsequently, the loose fibers of the three-dimensional fluffy layer region (2) provide electrostatic adsorption and retention to the deeper layers. [Explanation of Symbols]
