Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-removing sheet having an adhesive surface for removing dust adhering to the surface of textiles such as clothes, and more particularly, to a portability having a size similar to that of a business card, The present invention relates to a dust-removing sheet that can be repeatedly used by simply rubbing dust adhered to an adhesive surface in running water.

[0002]

2. Description of the Related Art Conventionally, dust tends to adhere to textiles such as clothing. Especially in dark suits such as black, dust is noticeable and must be constantly removed. A brush or the like is also used, but it is not enough, and there is a method of hitting with an adhesive tape. As a more sophisticated method, there has been a card-shaped sheet on one side of which an adhesive having an adhesive property suitable for removing dust from textiles has been applied. This sheet is generally about the size of a business card, that is, about 9 cm long and 5.5 cm wide, and is suitable for carrying.

[0003]

However, the card-type dust-removing sheet is too small to be used in dust-removing and is difficult to handle.
Further, when not in use, the adhesive surface is exposed and sticky, and further loses the adhesiveness. Therefore, it is necessary to cover and protect the adhesive surface with release paper of the same shape. If it is a disposable type, it does not matter, but if it is a repetitive type that uses at least two times, it will not align when you put this release paper after use, part of the adhesive layer will be exposed and it will be sticky or There was a drawback that it protruded and bent.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems.
A 100 mm plastic sheet is longitudinally folded in two so that one surface protrudes 0.5 to 3 mm from the other surface, and the protruding surface is a cover sheet that is not coated with an adhesive. Is provided with a removable pressure-sensitive adhesive layer having an uneven shape to form an adhesive surface, and the unevenness is applied at a rate of 15 to 700 per 1 cm ² .

In the present invention, the size of the adhesive surface is approximately 45 to 70 mm in width and 80 to 100 mm in length, which are almost the same as those of a business card, and a cover of approximately the same size is formed through an inward fold line provided on one vertical side. The sheet is extended. Therefore, when stored, it is the same size as a business card, so that it can be stored together with business cards and various cards in pockets, business card holders, card holders, wallets, etc., and the cover sheet can be opened and used as necessary. . In use, the size is doubled, so that it is easy to use, and there is no displacement of the cover sheet during storage.

[0006] Although the adhesive area is reduced by providing irregularities on the adhesive surface, the fiber pieces tend to adhere to the fiber product, and the dust sheet of the present invention mainly adheres to the fiber pieces. When the state attached to the sheet is enlarged and observed, the fiber pieces are attached over a plurality of irregularities. Therefore, if the adhesive itself has a sufficient adhesive force, a part of the dust fibers adheres to the adhesive and has an effect of peeling the dust fibers from the surface of the textile. Further, since the adhesive strength as a whole is apparently reduced, the sticky feeling at the time of use is reduced, and it is easy to handle.

When the cover sheet is peeled off while the adhesive surface is protected by the cover sheet, it is difficult to start peeling because the entire periphery of the cover sheet is in close contact. Therefore, by making the cover sheet shorter by 0.5 to 3 mm than the adhesive surface, the sheet can be easily opened without leaving wrinkles on the sheet.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As a plastic sheet material used as a substrate in the present invention, all plastics for sheet or synthetic paper such as polypropylene, polyester, polyvinyl chloride and synthetic paper can be used. The thickness of the base sheet is thin enough to be easily folded in two, and needs to be hard enough to open and close in a state of being in close contact with the adhesive surface so as not to cause wrinkles.
It is about 00 to 500 μm, preferably about 200 to 400 μm. The size of the base sheet is 90 to 140 mm x 80
~ 100mm, preferably 100 ~ 120mm x 85 ~
95 mm is easy to handle. Further, an inward fold line is formed at a substantially central portion of the sheet, and the sheet is folded and used.

FIG. 1 is a plan view of the inside of the open state of the present invention, and FIG. 2 is a perspective view of the closed state. When folding it in half, shift it slightly instead of at the center,
Are provided in the vertical direction. That is, the adhesive surface 3 is slightly shorter than the cover sheet 2 in the folded state, and the cover sheet protrudes 0.5 to 3 mm, preferably 0.8 to 1.5 mm. When the adhesive sheet 3 and the cover sheet 2 are in close contact with each other and the entire sheet is warped in the direction in which the cover sheet is peeled off from the adhesive face while putting a finger, the cover sheet 2 and the adhesive sheet 3 can be easily opened while grasping the cover sheet. .

As the pressure-sensitive adhesive, a removable pressure-sensitive adhesive is used. In particular, the adhesive surface after use, which has lost its adhesive strength due to the adhesion of a lot of dust to the surface of the adhesive, can be removed by simply rubbing with running water, and the adhesive surface is exposed and can be used repeatedly as a dust removal sheet Is preferred.

As such an adhesive, a removable type (remo
vable type, removable type) acrylic adhesive,
Preferably, a crosslinked acrylic pressure-sensitive adhesive is used. In addition, a permanent adhesive type (permanent type) adhesive is unsuitable. The adhesive strength is JIS Z 023
7, it is 400 to 50 g / 10 mm, preferably 250 to 50 g / 10 mm. As a commercially available product, Nitto Chemical Co., Ltd. 535A or No. 537B or the like can be used.

Since the dust removing sheet of the present invention has a folded shape almost similar to a business card, it can be stored in a pocket, a card case, a wallet, a business card case, or the like. Therefore, as shown in FIG. 2, it can be handed over to the consumer as a sales promotion product for business, and the shop name, telephone number, business item, and other business items can be described on the folded surface.

In the production, a base film, in FIG.
Attach the strongly adhesive surface of the double-sided adhesive tape with significantly different adhesive strengths on both sides. At the time of sticking, the sheet is stuck to the part to be the adhesive surface 3 and is not stuck to the part to be the cover sheet 2, but is stuck as a whole. Then, it can be manufactured at once by cutting to a predetermined size and pressing the inner folding line 1. Alternatively, the double-sided pressure-sensitive adhesive tape may be used, and the re-peelable pressure-sensitive adhesive may be applied in the form of a stripe while leaving the width of the cover sheet 2 at the width of the pressure-sensitive adhesive surface 3.

It is preferable that the removable pressure-sensitive adhesive layer has irregularities. The unevenness may be formed by dispersing minute depressions, dispersing minute projections, or waving the whole in the adhesive layer. The number of irregularities both per 1cm ² vertically and horizontally, 15
７００700, preferably 50-500. 1cm
^{If the} number exceeds 700 per ² cm, the dust removal effect of the fiber product is insufficient, and if it is less than 15 per 1 cm ² , it is difficult to peel off the adhesive surface. The number of irregularities is the number of protrusions or depressions existing in 1 cm ² in the horizontal and vertical directions when the irregularities are projections or depressions. If the whole is wavy, the number of wave peaks or wave bottoms is counted in the same manner as the projections or depressions . In the case of a waveform in which a large wave is accompanied by a small wave, the large wave is generally counted.

There is no particular limitation on the method of providing the irregularities. For example, a re-peelable pressure-sensitive adhesive film with a release liner
You may emboss at 0-50 degreeC, and may adhere | attach to a base material.
In addition, embossing can be performed for all the substrates together. Further, after applying a re-peelable pressure-sensitive adhesive or pasting a double-sided pressure-sensitive adhesive tape to the substrate through the surface having been subjected to anchor coating or corona treatment, embossing can be performed collectively. The uneven surface may be provided not only on the adhesive surface 3 but also on the cover sheet 2.

[0016]

EXAMPLE A 300 μm thick polyvinyl chloride sheet was used as a base sheet. 535A (manufactured by Nitto Kagaku Co., Ltd.) was adhered at a width of 55 mm with an interval of 56 mm. The adhesive surface of the double-sided adhesive tape is the adhesive surface 3,
The surface to which the double-sided pressure-sensitive adhesive tape was not attached is the cover sheet 2. In this state, the adhesive surface 3 is covered with a release liner. The inner folding line 1 is press-formed at the boundary between the cover sheet 2 and the adhesive surface 3 and the width of the cover sheet is 56 m.
m, the adhesive surface was cut into a width of 55 mm and a length of 88 mm to obtain a dust removal sheet of the present invention.

The uneven surface was embossed at 40 to 50 ° C. on the surface to which the removable acrylic adhesive was stuck. In this example, the adhesive strength was 245 g / 10 mm. The folded sheet was opened, and a dusty portion such as a suit, a sweater, and a blouse was lightly tapped to remove dust. The dust-removing sheet having lost the adhesive strength was lightly rubbed on the adhesive surface 3 in running water, so that the dust fell as a lump and the adhesive adhesive surface was exposed again.

[0018]

According to the present invention, the surface of textiles such as clothing is thin and small and easily stored in pockets, card holders, wallets, business card holders, etc., and easily doubles in size when used. It is easy to remove dust adhering to the surface, and the adhesive surface reappears only by rubbing the dust adhered to the adhesive surface in running water,
A dust sheet that can be used repeatedly can be obtained.
