SUMMARY OF THE INVENTION The present invention solves the above problems and aims to utilize the entire surface of the wiper.

[0004]

Means for Solving the Problems A wiper according to the invention of the present application is such that a wiper sheet has two or more finger insertion portions and a fixing portion that fixes a hand when the fingers are inserted into any one of the finger insertion portions. Specifically, the present invention relates to a wiper which is formed from a wiper sheet and a sheet whose periphery is joined, and the joined sheet is cut at at least two places with a central portion sandwiched therebetween.

[0005]

The wiper according to the invention of the present application is characterized in that the wiper sheet has two or more finger insertion portions and a fixing portion that fixes the hand when the fingers are inserted into any one of the finger insertion portions. Since the wiper is formed from various directions and the hand can be inserted from various directions, the entire surface of the wiper can be used without waste.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The shape of the wiper is preferably an elliptical shape, an oval shape, a circular shape, a rectangular shape, a square shape, or a composite shape thereof as shown in FIG. From the viewpoint of use, the oval shape is particularly preferable, and the rectangular shape is particularly preferable from the viewpoint of being able to clean the end of the object to be cleaned.

The finger insertion portion 2 is only required to be able to hold the wiper 1 firmly by the finger.
One space 6 into which the entire finger can be inserted, as shown in (a)
2 or 5 as shown in FIG. 2 and FIG. 5B so that the fingers can be individually inserted. In the case of a space, the wiper can be wiped at any place by moving the finger in the finger insertion portion 2, and thus the wiper can be used without waste, which is preferable. In addition, two or more finger insertion portions may be provided along the outer circumference of the wiper.

The fixing portion 4 for fixing the hand may be any one that can contact the back of the hand when the hand is inserted into the finger insertion portion 2 and fix the hand and the wiper, such as a sheet or tape. The width is preferably 1 cm or more so that the hand can be securely fixed to the wiper by contacting the back of the hand in a planar manner, and 5 to 10 cm is particularly preferable, although it depends on the size of the wiper. As shown in FIG. 3 or 4, the sheet-shaped hand fixing portion 4 may be provided with a thumb insertion portion 3 so that the hand can be more fixed to the wiper. An elastic material may be used in consideration of fixing the hand and inserting the hand.

As shown in FIG. 1, the wiper sheet and the peripheral portion of the sheet serving as the finger insertion portion and the fixing portion of the hand are previously joined and integrated by a thread 7 or the like, and the central portion is sandwiched between at least 2 sheets. The cut portion is particularly preferable because the finger can be freely moved within the finger insertion portion 2, so that the entire surface of the wiper can be used more easily and can be easily produced.

The wiper sheet 5 and the sheet to be the finger insertion portion 2 and the hand fixing portion 4 are joined by a usual joining means, but sewing with a thread 7 or heat fusion is preferable. For the sewing, it is preferable to use a conductive thread as the thread because it is excellent in static elimination.

The finger insertion part and the hand fixing part are
It can be formed by cutting the sheet after joining it with the wiper sheet, or by preparing a sheet for the finger insertion portion and a sheet for the hand fixing portion as shown in FIG. It may be joined to the sheet.

The finger insertion part 2 and the hand fixing part 4 are made of a one-layer or multi-layer structure, and a cloth, a film, a paper or the like is used, and the cloth may be a non-woven fabric, a woven fabric, a knitted fabric or the like. used. The finger insertion part 2 and the hand fixing part 4
When the sheet is sandwiched between the wiper sheets 5, the wiper sheets on both sides can be used, so that the wiper sheet can be used for a longer time.

As shown in FIG. 5, a wiper sheet 5 is provided.
Is preferably reinforced with a non-woven fabric having excellent strength. When a bulky nonwoven fabric or a cotton layer is formed between the wiper sheet and the nonwoven fabric having excellent strength, it has excellent cushioning properties and workability.

The wiper sheet will be described in detail below. Fibers that can be used in the wiper sheet of the invention of the present application include, for example, natural fibers such as silk, wool, cotton, and hemp,
Recycled fiber such as rayon fiber, semi-synthetic fiber such as acetate fiber, polyamide fiber, polyvinyl alcohol fiber, acrylic fiber, polyester fiber, polyvinylidene chloride fiber, polyvinyl chloride fiber, polyurethane fiber,
Synthetic fibers such as polyethylene fibers, polypropylene fibers and aromatic polyamide fibers can be used. Further, a core-sheath type, a side-by-side type, or the like composite fiber composed of two or more resin components may be used. When the wiper sheet is made of a fiber sheet mainly composed of rayon fiber, it is excellent in water absorption, and is suitable for use in a place with a lot of water such as a kitchen.

Further, the wiper sheet is a fine fiber derived from a composite fiber (hereinafter referred to as "fine fiberized fiber") capable of being finely fiberized into a fine fiber having a fiber diameter of 1 to 10 μm by a mechanical and / or chemical treatment. When the fibers and fine fibers having a fiber diameter of 0.01 to 10 μm formed by the melt-blowing method are included, the cleaning property of the cleaning target and the retention of the cleaned dust are excellent, and the cleaning target is less likely to be damaged. Therefore, it can be preferably used. The fine fibers derived from the former fine fiberized fibers are stretched and are more excellent in strength, and therefore can be used more suitably.

As the fine fiber, as shown in FIG. 7, a sea-island type fiber having a cross section in which another component B is arranged in an island shape in one component A, and as shown in FIG. Other component B
A multi-bimetal type fiber having a cross section in which and are alternately laminated in layers, or as shown in FIGS. 9 (a) and 9 (b), one component A
A chrysanthemum-shaped fiber having a cross section divided by another component B extending from the center of the fiber to the fiber surface can be exemplified. Among these, a multi-bimetal type fiber or a fine fiber derived from the chrysanthemum-shaped fiber has a substantially trapezoidal shape or a fan shape. Since it has a modified cross-sectional shape such as a shape and is more excellent in cleanability, it can be suitably used. In the case of a fiber having this irregular cross-sectional shape, the value converted into a circular cross-section is the fiber diameter.

The resin component constituting the fine fiber is
As long as it is composed of two or more components, the combination of two components may be, for example, a polyamide resin and a polyester resin, a polyamide resin and a polyolefin resin, a polyester resin and a polyolefin resin, or a polyester resin and a polyresin. Examples include acrylonitrile resin, polyamide resin and polyacrylonitrile resin, polyolefin resin and polyacrylonitrile resin.

The fine fibers derived from such fine-fiberized fibers are preferably contained in the wiper sheet in an amount of 5% by weight or more.
The content is more preferably 0% by weight or more, and most preferably 90% by weight or more.

A sheet for wiper is formed by using such fibers. The fibrous sheet includes, for example, non-woven fabric, woven fabric, knitted fabric, etc., and since the non-woven fabric has a three-dimensional void and can easily form a void that can hold dust wiped from the object to be cleaned, it is preferably used. it can. This non-woven fabric is formed, for example, by intertwining a fibrous web obtained by a dry method such as a card method, an air laid method, a spun bond method, a melt blow method, or a wet method with a mechanical external force such as a fluid such as water or a needle. it can. Entangling with the former fluid is more preferable because a non-woven fabric that is more uniform and excellent in strength and is flexible can be obtained.

When the fibrous web is formed by the card method, when a crossed fibrous web in which the orientation directions of the fibers are crossed by a cross layer is included in the longitudinal direction of the fibrous web, the fibrous web is included. Since the strength in the width direction is improved and cleaning can be performed without directivity, it is a more preferable orientation direction.

In order to improve the strength and abrasion resistance of the non-woven fabric, it may be fused with a binder such as an emulsion type, a solvent type, a powder type, or the fibers constituting the non-woven fabric, but the cleaning property is not deteriorated. It is preferable to partially fix them. When fixing this partly, the strength by fixing,
In order to improve wear resistance and prevent deterioration of cleaning property, it is preferable that each fixed area is 0.01 to ⁵ mm ² , and the total fixed area is 5 to 50% of the total area of the nonwoven fabric. Among these, the method of partially fusing the non-woven fabric constituent fibers with an embossing roll or ultrasonic waves does not cause falling off during use of the wiper as in the case of fixing with a binder, and is excellent in cleanability. , A more suitable method.

When a mechanical external force such as a fluid or a needle is applied to the fiber web containing the finely-fiberized fibers of the above-mentioned multiple bimetal type fibers or chrysanthemum type fibers, the fine fibers are entangled at the same time as the fine fibers are derived. Therefore, it is a rational method for forming a non-woven fabric that does not require any additional derivation step. Further, since the fine fibers are entangled with each other to form a dense structure, there is also a feature that it is more excellent in retaining dust and the like.

The fiber sheet thus formed may be used as it is as a wiper sheet. However, when the fiber sheet is coated with an electron-conjugated polymer, the wiper sheet is excellent not only in cleaning property but also in static elimination property. Since it can be formed into a sheet, it is suitable for use in a place where static electricity is a problem. Although the fiber sheet may be formed from the fiber coated with the electron-conjugated polymer, the electron-conjugated polymer may be damaged when the fiber sheet is formed. It is preferably coated with a base polymer. Since these fibrous sheets are porous, almost the entire fibrous sheet can be coated with the electron-conjugated polymer. Since this electron-conjugated polymer has good adhesion to fibers and is therefore excellent in durability and flexibility, it can be discharged and cleaned without damaging the object to be cleaned.

The surface resistance of the fiber sheet containing the fibers coated with the electron-conjugated polymer is preferably 1 × 10 ⁹ Ω / □ or less. If the surface resistance exceeds 1 × 10 ⁹ Ω / □, the static elimination performance deteriorates. Therefore, 1 × 10 ⁶ Ω / □ or less is more preferable, and 1 × 10 ⁴ Ω / □ or less is most preferable.

As a method of coating with this electron-conjugated polymer, for example, a solution containing an oxidizing agent such as iron (III) chloride or copper (II) chloride may be impregnated into a fiber sheet and then contacted with a monomer for polymerization. good. As a method for contacting the monomer, when the monomer is in a liquid state, the fiber sheet to which the oxidant is attached may be impregnated, coated or sprayed with the monomer. The fiber sheet to which the oxidant is attached may be placed on the. Examples of the monomer that constitutes the electron conjugated polymer include acetylene, benzene, aniline, phenylacetylene, pyrrole, furan, thiophene, indole, and derivatives of these monomers. Among these, pyrrole is excellent in electrical conductivity and polymerizability, and also excellent in static eliminability and durability, and thus can be used particularly preferably.

If the entire fiber sheet is coated with this electron-conjugated polymer, the charge removal property is excellent, but the fiber sheet may be partially coated. The fiber sheet coated with the electron-conjugated polymer is preferably a fiber sheet having a fiber diameter of 1 to 10 μm, which is more excellent in static elimination property, and a fiber having an irregular cross section and excellent in static elimination property is preferable. Those containing fine fibers derived from fine fibers of bimetal type fibers or chrysanthemum type fibers are preferable.

The wiper of the present invention is a table,
Furniture such as desks, chests, cabinets, chairs, sitting sets, sideboards, TVs, washing machines, refrigerators, microwave ovens, lighting appliances, musical instruments such as pianos and electric tones, golf clubs, sports equipment such as ski equipment. , Bags such as handbags, bags, trunks, automobiles before painting, wood products, resin products, windows, mirrors, foreheads, doors,
Suitable for cleaning floors, Buddhist altars, inside or outside cars, lacquerware, etc.

Examples of the invention of this application will be described below, but the invention is not limited to the following examples. The surface resistance is a value measured by Loresta AP MCP-T400 (manufactured by Mitsubishi Petrochemical Co., Ltd.).
