Abstract

【Task】
Provided is a wiping sheet that can be attached to a device body such as a cellular phone or a case many times, does not leave an adhesive, and does not reduce the adsorptive power.
A super-fine fiber cloth and an adsorbing acrylic polymer sheet are bonded together to form a wiping sheet, which is always adsorbed and held on a mobile phone or the like. When wiping the screen dirt, peel off the sheet and press the ultra-fine fiber cloth side against the screen.

Description

  The present invention relates to a sheet for wiping that wipes off dirt such as screens of mobile phones, car navigation systems, personal computers, etc., optical lenses such as cameras, and CD mirror surfaces, and that can be repeatedly attached to and detached from these equipment bodies or cases. is there.

  Conventionally, fabrics made of ultrafine fibers have been used for wiping off dirt such as glasses. In addition, in order to wipe off the dirt on the screen of the mobile phone, a sheet that has been detachably attached to the main body of the mobile phone by attaching a sheet having an adhesive layer to the back surface of the fabric has been proposed.

  However, it is not preferable that the sheet having the above-mentioned pressure-sensitive adhesive layer is attached because the pressure-sensitive adhesive may remain in the main body when being peeled off from the main body of the mobile phone. Further, when the sheet is repeatedly peeled off, the adhesive strength is lowered, and there is a possibility of dropping off. Furthermore, when a woven fabric is used as the ultra-fine fiber cloth, there are disadvantages that it is inferior in dimensional stability at the time of printing, cutting, punching machine processing, etc., and that fraying of the cloth and dust are likely to occur.

  Therefore, the present invention has an object to provide a wiping sheet that can be re-applied to a mobile phone or the like many times, does not leave an adhesive on the main body, and does not decrease the adsorbing force indefinitely. By adopting a non-woven fabric as an ultra-fine fiber cloth, it is possible to provide an excellent wiping sheet that is excellent in dimensional stability during printing, cutting, punching machine processing, etc., and does not generate fraying or dust. Let it be an issue.

  In order to solve the above-described problems, a polymer sheet was devised by bonding an ultra-fine fiber cloth and an acrylic polymer sheet having adsorptivity by a sucking action of fine bubbles. Furthermore, the sheet | seat which uses a nonwoven fabric as a super extra fine fiber cloth was devised.

As described above, since the wiping sheet in the present invention does not use an adhesive on the back surface, it has an advantage that the adhesive does not remain in the device main body or the case that is the adherend surface.

Further, by using a non-woven fabric as the fiber cloth, a wiping sheet having excellent dimensional stability and free from fraying and dust during cutting and punching can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a wiping sheet according to the present invention. Here, 1 indicates a super fine fiber cloth. As an example of this ultra-fine fiber cloth, there is a woven fabric Zawina Minimax using Beluma X manufactured by Kanebo Gosei Co., Ltd. as a raw yarn. In addition, examples of non-woven fabrics of ultra-fine fibers include Bifresher manufactured by Japan Vilene, Apollon, and “Electrical Tol”, which has electrostatic removal performance manufactured by the same company.

2 shows an adsorptive acrylic polymer sheet having fine bubbles on its surface. In the acrylic polymer sheet used here, fine bubbles on the polymer surface act like a suction cup and are adsorbed on a smooth surface. An example of such a sheet is Celopy 555 manufactured by Taisei Laminator Co., Ltd. This polymer sheet consists of low foamed foam with a foaming ratio of about 1.5 times. This sheet has a thickness of 0.5 mm and a square of 50 mm, and exhibits a peeling peel strength of about 0.15 kg against glass.

3 shows the adhesive or adhesive used in order to bond a fiber cloth and a polymer sheet.

The wiping sheet of the present invention can be used, for example, by adsorbing and holding the polymer sheet side to the main body of a mobile phone or the like as shown in FIG. 2, and then removing the sheet from the main body when wiping off the screen. Wipe the ultra-fine fiber cloth side against the screen.

In addition to mobile phones, this sheet can also be used for wiping off dirt from car navigators, personal computers, calculators, hand mirrors, watches, CD boards, and the like.

It is a perspective view of the sheet | seat for wiping of this invention. The state where the sheet for wiping of the present invention is sucked and held by the mobile phone is shown. The state where the wiping sheet of the present invention is held by suction on a notebook computer is shown. The state where the CD mirror surface is wiped using the wiping sheet of the present invention is shown. The state which wipes the screen of a mobile telephone using the sheet | seat for wiping of this invention is shown.
