Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present application, it is to be noted that, unless otherwise specified, "a plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," and the like, indicate an orientation or positional relationship that is merely for convenience in describing the application and to simplify the description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the application.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; can be directly connected or indirectly connected. The specific meaning of the above terms in the present invention can be understood as appropriate to those of ordinary skill in the art.

As shown in FIG. 1, the improved wiping cloth of the embodiment comprises a rough melt-blown layer 1, the fibers of the rough melt-blown layer 1 comprise first fibers 11 and second fibers 12, the average diameter of the first fibers 11 is larger than the average diameter of the second fibers 12, and the difference between the average diameters of the first fibers 11 and the second fibers 12 is not less than 5 μm. Further, the difference in the average diameter of the first fibers 11 and the second fibers 12 is 25 μm. The first fiber 11 and the second fiber 12 are made of high polymer materials with different melt indexes, and are simultaneously spun by two sets of spinning assemblies. Alternatively, the number of fibers in the matte meltblown layer 1 may be three, four, five or even more, with the frictional force depending on the average diameter difference between the fibers.

The average diameter of the first fibers 11 in the examples was 30 μm; the second fibers 12 have an average diameter of 5 μm, the first fibers 11 account for 60% of the total mass of the matte meltblown layer 1, and the second fibers 12 account for 40% of the total mass of the matte meltblown layer 1.

In another embodiment, as shown in fig. 2, the wiping surface of the matte meltblown layer 1 is a concave-convex surface having concave and convex portions. The concave-convex surface may be: the wave shape is alternated, or the convex part is convex points with any shape, the concave part is net-shaped between the convex points, or the concave part is concave points with any shape, and the convex part is net-shaped between the concave parts.

The convex parts are hexagonal salient points 1a which are uniformly distributed, and the concave parts are continuous nets which are arranged among the salient points 1 a. The top surfaces of the convex parts are positioned in the same wiping plane, the interval width of the convex parts is less than the width (diameter or side length) of the convex parts, and the area of the convex top surfaces of the wiping surface is greater than that of the concave parts. The contact area of the wiping cloth with the concave-convex structure and a wiped substance is larger, and the wiping surface has larger friction force when the wiping cloth is combined with the rough melt-blown layer 1 with the fiber diameter difference.

As shown in fig. 3, in another embodiment, the skin-friendly layer 2 is further included, the skin-friendly layer 2 is compositely connected with the rough melt-blown layer 1, in the composite structure of the skin-friendly layer 2, the wiping surface with the salient points 1a is a surface, and the surface of the rough melt-blown layer 1 with the reticular protrusions is composited with the skin-friendly layer 2. The skin-friendly layer 2 and the rough melt-blown layer 1 are bonded and compounded through ultrasonic points; the ultrasonic points are arranged in the concave parts of the rough melt-blown layer 1. Specifically, the skin-friendly layer 2 is a spunlace nonwoven fabric, and compared with the rough melt-blown layer 1, the spunlace nonwoven fabric has fine hand feeling and good water absorption and moisture absorption.

The rough melt-blown layer 1 is a polypropylene melt-blown layer. The polypropylene has high crystallinity, regular structure, good strength, hardness, elasticity and lipophilicity, the improved wiping cloth meets the use requirements of scraping stubborn dirt, oil stain and the like inside and outside utensils such as a pot and a bowl without using detergent under a humid condition, and compared with wood pulp cloth, the improved wiping cloth has better scraping and wiping effects; improved cleaning hygiene of the wipes, as compared to cotton, also reduces the use of detergents and the like.

According to the GBT 22895-2008 'plane method for measuring static and dynamic friction coefficients of paper and paperboard', the static friction coefficient of the rough melt-blown layer is more than 0.800, and the dynamic friction coefficient is more than 0.600.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
