  The cleaning article of Patent Document 1 includes a fiber layer and a nonwoven fabric sheet as constituent requirements. However, when used in the wet type, if a fiber layer is present, the fibers are converged and temporarily attached by the cleaning liquid, so that sufficient cleaning properties cannot be obtained.

  On the other hand, in the cleaning article of Patent Document 2, an attempt is made to solve this problem by including a cleaning composition in a hydrophilic nonwoven fabric sheet. FIG. 10 of Patent Document 2 shows a plurality of hydrophilic nonwoven fabrics. An embodiment consisting of a sheet is described.

  However, in the cleaning article as in Patent Document 2, when a plurality of hydrophilic non-woven sheets are impregnated with a cleaning liquid, adjacent non-woven sheets are temporarily attached to each other by the cleaning liquid, so that a sufficient cleaning effect can be obtained. There was no problem.

  Moreover, in this aspect, it is difficult to control the amount of the cleaning liquid impregnated for each of the plurality of nonwoven fabric sheets. That is, the amount of the cleaning liquid is uneven between the nonwoven fabric sheets depending on the storage state. For this reason, the amount of impregnation of the cleaning liquid that is always stable on the cleaning surface cannot be maintained for a long time.

  The present invention solves the above-mentioned problems, for example, is a handy type cleaning article that prevents temporary attachment between adjacent nonwoven fabric sheets and maintains a stable amount of impregnation of the cleaning liquid during cleaning and storage. An object of the present invention is to provide a wet type cleaning sheet capable of maintaining excellent cleaning properties for a long period of time and a cleaning article using the same.

  The present inventors do not use a fiber bundle such as so-called tow, but constitute a brush portion only with a nonwoven fabric sheet having strips, and in addition, from a hydrophilic nonwoven fabric impregnated with a cleaning liquid or impregnated in the future It discovered that said subject could be solved by laminating | stacking and arrange | positioning the 2nd nonwoven fabric sheet which consists of hydrophobic nonwoven fabrics between the 1st nonwoven fabric sheets which came, and came to complete this invention. Specifically, the present invention provides the following.

(1) A disposable cleaning sheet having a brush portion,
The brush part is laminated by bonding a plurality of non-woven sheets in which a plurality of strips are formed in a predetermined joining region,

  According to the present invention, for example, a cleaning sheet for a handy-type cleaning article, which prevents temporary attachment between adjacent non-woven sheets, can maintain a stable amount of cleaning liquid impregnation during cleaning and storage, and is excellent. A wet-type cleaning sheet that can maintain the cleanability for a long period of time and a cleaning article using the same can be provided.

It is a cleaning article which is one embodiment of the present invention, and is a perspective view showing a state where a gripping tool is mounted on a cleaning sheet which is one embodiment of the present invention. It is a top view of the sheet for cleaning which is one embodiment of the present invention. It is a bottom view of the cleaning sheet which is one embodiment of the present invention. It is AA sectional drawing of the sheet | seat for cleaning in FIG. It is a disassembled perspective view of the cleaning sheet.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

<Overall configuration>
As shown in FIG. 1, the cleaning article 300 in this embodiment includes a gripping tool 200 and a disposable cleaning sheet 100. The gripping tool 200 includes two insertion portions 210 a and 210 b that are divided into two from the base portion 210 and extend substantially in parallel. The insertion portions 210 a and 210 b are cleaned by being inserted into the insertion spaces 150 and 150 of the cleaning sheet 100. The product 300 can be used.

  2 and 5 together, the cleaning sheet 100 is configured by laminating a plurality of non-woven sheets 110 as a whole, and all the non-woven sheets are line seal portions 160 (in the present invention) at the center in the longitudinal direction. Are equivalent to the joining region in FIG. The insertion spaces 150 and 150 of the cleaning sheet 100 are composed of the nonwoven fabric sheet 111 of the uppermost layer (the first layer from the top in FIG. 5) and the nonwoven fabric sheet 112 of the second and third layers. The insertion spaces 150 and 150 are formed by surrounding the layer with the point seal portion 170, and constitute a mounting portion of the gripping tool 200.

  As shown in FIG. 5, the nonwoven fabric sheets 111 and 112 constituting the mounting portion and the seven nonwoven fabric sheets 115 of the fourth layer to the tenth layer are joined and integrated by the line seal portion 160 in a superposed state. Is formed.

<Brush part>
As shown in FIG. 4, the seven nonwoven fabric sheets 115 from the fourth layer to the tenth layer in this embodiment constitute a brush portion in the present invention. The planar shape of each nonwoven fabric sheet is a rectangular nonwoven fabric sheet, and a plurality of strips 110b based on the line seal portion 160 are formed by tooth-shaped zigzag cut lines 110a from the edge portions on both sides in the longitudinal direction. Is formed. This strip has a free end, thereby exerting a cleaning effect due to the brush performance.

  In this embodiment, a strip piece is also formed in part in the second layer nonwoven fabric sheet 112 constituting the insertion spaces 150 and 150, and this strip piece also constitutes a brush portion.

  Specifically, in the brush portion constituted by the nonwoven fabric sheet 115 in the present invention, the first nonwoven fabric sheet 115a made of a hydrophilic nonwoven fabric and the second nonwoven fabric sheet 115b made of a hydrophobic nonwoven fabric are alternately laminated. The second nonwoven fabric sheet 115b is arranged between the first nonwoven fabric sheets 115a.

<First nonwoven fabric sheet>
The first nonwoven fabric sheet 115a made of a hydrophilic nonwoven fabric may be a nonwoven fabric containing 10% by mass or more, preferably 30% or more, particularly preferably 50% or more of conventionally known rayon, pulp, PVA, etc. as constituent raw material fibers. Good. It is not always necessary to use a hydrophilic fiber alone. Even if a hydrophobic thermoplastic resin such as polyethylene, polypropylene or polyester is contained in an amount of less than 90% by mass, preferably less than 70%, particularly preferably less than 50%, Fiber. Specifically, 60% hydrophilic fiber / 40% hydrophobic fiber can be exemplified. By including a certain amount of the hydrophobic resin in this way, it is preferable because joining and integration between the nonwoven fabric sheets can be performed by welding and sealing with heat, ultrasonic waves, or the like. The first nonwoven fabric sheet 115a can be formed by a conventionally known spunlace method or the like.

  The surface of the first nonwoven fabric sheet 115a made of a hydrophilic nonwoven fabric may be provided with an uneven shape with a maximum height difference of about 0.1 mm to 5 mm by embossing or the like. Thereby, the temporary attachment of adjacent nonwoven fabric sheets can be prevented more effectively, and the cleaning performance can be improved.

  The first nonwoven fabric sheet 115a made of a hydrophilic nonwoven fabric is arranged in at least two layers, and preferably, the first nonwoven fabric sheet 115a is arranged in the outermost layer on the cleaning surface side. By arranging the hydrophilic nonwoven fabric in the outermost layer on the cleaning surface side, the cleaning effect as a wet type is sufficiently exhibited.

<Second non-woven sheet>
The second nonwoven fabric sheet 115b made of a hydrophobic nonwoven fabric may be any nonwoven fabric that contains 90% by mass or more of a conventionally known hydrophobic thermoplastic resin such as polyethylene, polypropylene, and polyester as constituent raw material fibers. It is not always necessary to use a hydrophobic fiber alone, and it is a hydrophobic fiber in the present invention even if it contains less than 10% by weight of hydrophilic fibers such as rayon, pulp and PVA. Specifically, 0% hydrophilic fiber / 100% hydrophobic fiber can be exemplified. The second non-woven fabric sheet 115b can be formed by a conventionally known through-air method or a spunbond method.

<Arrangement and effect of nonwoven fabric sheet>
(1) In the present invention, the second nonwoven fabric sheet 115b made of a hydrophobic nonwoven fabric serves as a partition by disposing the second nonwoven fabric sheet 115b made of a hydrophobic nonwoven fabric between the first nonwoven fabric sheets 115a of the hydrophilic nonwoven fabric. Then, the space between the first nonwoven fabric sheets 115a of the plurality of hydrophilic nonwoven fabrics is divided. Thereby, it can prevent effectively that the 1st nonwoven fabric sheet 115a of a hydrophilic sheet | seat temporarily adheres with a washing | cleaning liquid, and brush performance falls.

  (2) Moreover, since the 1st nonwoven fabric sheet 115a of each hydrophilic sheet exists independently by the partition effect of the 2nd nonwoven fabric sheet 115b, the movement of the washing | cleaning liquid between the nonwoven fabric sheets 115a is suppressed, and dispersion | variation exists. It does not occur and stable cleaning ability can be maintained.

  (3) Furthermore, since the partition by the second nonwoven fabric sheet 115b made of a hydrophobic nonwoven fabric also suppresses water evaporation from the first nonwoven fabric sheet 115a of each hydrophilic sheet, it is possible to maintain a stable cleaning ability for a long period of time. it can.

  As for the arrangement relationship between the first nonwoven fabric sheet 115a of the hydrophilic nonwoven fabric and the second nonwoven fabric sheet 115b made of the hydrophobic nonwoven fabric, the outermost layer on the cleaning surface side is the first of the hydrophilic nonwoven fabric as in the embodiment shown in FIG. Although it is preferable to arrange the non-woven fabric sheet 115a and the first non-woven fabric sheet 115a and the second non-woven fabric sheet 115b alternately from the non-woven fabric sheet 115a, it is not necessarily limited thereto, and one or a plurality of first non-woven fabric sheets 115a / one or a plurality of second The configuration of the nonwoven fabric sheet 115b / one or more first nonwoven fabric sheets 115a / one or more second nonwoven fabric sheets 115b /... Is also an aspect of “alternating” in the present invention.

<Cleaning liquid>
The present invention is suitably used as a so-called wet type, and after the cleaning sheet or brush portion of the present invention is manufactured, the cleaning liquid is impregnated by a predetermined method. At this time, as described above, the water-based cleaning agent is impregnated in the first nonwoven fabric sheet 115a of the hydrophilic nonwoven fabric, but is hardly impregnated in the second nonwoven fabric sheet 115b made of the hydrophobic nonwoven fabric. As a result, the partition effect of the second nonwoven fabric sheet 115b as described above is exhibited.

  The cleaning liquid is preferably an aqueous cleaning liquid in which 95% or more is water, and contains 100% water. In addition, conventionally known surfactants, alcohols, solvents, preservatives, deodorants, fragrances and the like are appropriately contained. The impregnation amount of the cleaning liquid is appropriately set to about 1 to 10 times, preferably about 3 times the dry weight of the cleaning sheet.

  In addition, the cleaning sheet of the present invention does not necessarily need to be impregnated with the cleaning liquid in advance, and includes one in which the user impregnates the cleaning liquid before use. Even in this case, the water-based cleaning agent is impregnated in the first nonwoven fabric sheet 115a of the hydrophilic nonwoven fabric, but is hardly impregnated in the second nonwoven fabric sheet 115b made of the hydrophobic nonwoven fabric. The partition effect of the nonwoven fabric sheet 115b is exhibited after impregnation.

  The present invention is, for example, a handy-type cleaning article, and can be suitably used as a wet-type cleaning article containing a cleaning liquid.
