点があった。Further, in the spun lace nonwoven fabric having a mesh pattern, strike-through (falling off) of dust collected from the mesh portion is not preferable. In response to this problem, a sheet in which unevenness is formed on the whole by performing embossing on a flat spunlaced nonwoven fabric has been proposed, but in this case, the fiber density becomes too high in the portion subjected to the shaping treatment, There was a problem that the performance of collecting rigid hair was deteriorated and the texture was impaired.

る。According to the present invention, a non-woven cloth sheet formed by hydroentangling is changed in fiber distribution by a laser processing machine to form irregularities having substantially the same fiber density on the entire surface of the sheet. The present invention relates to a cleaning sheet characterized by the above. Further, the sheet of the present invention has at least two regions having different thicknesses to form uncompressed unevenness on the entire surface of the sheet, and each region has a different thickness, but all regions have substantially the same fiber. The present invention relates to a cleaning sheet having a density. The method of forming the non-compressed unevenness on the entire surface of the sheet of the present invention is by laser processing for the entangled non-woven fabric, for example, the laser processing for the entangled non-woven fabric is performed by polymer Group, Inc. APEX Technology.
Achieved by Utilizing this technique, a design optimized for dust and hair collection performance can be provided.

ーン等が利用可能である。The fiber composition of the sheet of the present invention may be any fiber as long as it is a fiber used in spunlace non-woven fabrics, for example, thermoplastic fibers such as polyester, polyamide and polyolefin, or their composite fibers, split fibers and cupra. Recycled fiber such as rayon, semi-synthetic fiber such as acetate, and natural fiber such as cotton are used. Regarding the fineness and fiber length of the sheet of the present invention, the fiber length is 5 to 10
0 mm is suitable, and if it exceeds this range, the suitability for the card process is deteriorated and the operability is impaired. The fineness is 0.
5 to 5.0 d is suitable. When the fineness is low, the fiber density is high and the ability to collect hair or the like is reduced, and when the fineness is high, the ability to collect and retain fine dust is reduced. In the sheet of the present invention, the unevenness formed on the entire surface of the sheet is generally applied to the sheet during cleaning of the flooring wiper.
cm 2 ), a plurality of regions having different thicknesses are formed.
When both sides of the sheet are used, the cross-sectional shape of the irregularities is preferably a state of irregularities on both sides as shown in FIG. However, in the fiber constitution of the present invention, since the sheet rigidity is appropriately low, the pressure distribution during the actual cleaning work does not significantly differ between the front and back even in the case of one-sided unevenness, and both sides can be used. In addition, there are no particular restrictions on the shape of the plurality of regions (recesses and protrusions) having different thicknesses,
It is possible to use geometric patterns such as lines, circles, polygons, and stars, various patterns such as logos, character strings, designs, characters, and irregular patterns.

Moreover, since these recesses are formed by non-compression, they have the same fiber density as the projections, and are optimized without dust space for dust collecting property and entanglement property of hair etc. in the entire collecting sheet. It can have a fiber density.
