The resultant laminate with the tacky layer 13 on the inside is subsequently wound onto a paper tube 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-removing pressure-sensitive adhesive tape wound around a winding core with an adhesive layer on the outside and a method for producing the same.

[0002]

2. Description of the Related Art It is known to remove dust and hair adhering to carpets, clothes, etc. by adhering to the adhesive layer of an adhesive tape. Further, there is also known a dust remover in which a pressure sensitive adhesive tape is used as a rolled body wound with the pressure sensitive adhesive layer on the outside, and is mounted on a rotary drum (Japanese Utility Model Publication No. 42-1185).

In order to manufacture a roll having such an adhesive layer on the outside, conventionally, as shown in FIG. 6, a release layer 12 is provided on one side of a base sheet 11 and an adhesive 14 is provided on the other side. The coated adhesive tape is temporarily wound with the adhesive layer 13 inside, and the rolled body B
(FIG. 6 (a)), and thereafter, the wound body B is unwound and rewound with the adhesive layer 13 on the outside (FIG. 6 (b)). Since the pressure-sensitive adhesive tape for dust removal thus obtained exposes the pressure-sensitive adhesive layer 13 on the outermost layer, a separately prepared release paper was wrapped around the outermost layer to obtain a product.

[0004]

The above-mentioned conventional manufacturing method requires a step of rewinding the pressure-sensitive adhesive tape wound with the pressure-sensitive adhesive layer 13 inside and rewinding with the pressure-sensitive adhesive layer 13 outside. Also, a device therefor is required.

The dust-removing pressure-sensitive adhesive tape manufactured in this manner is difficult to handle because the pressure-sensitive adhesive layer 13 is exposed at the outermost layer, so that it can be bonded anywhere. Therefore, it is necessary to separately prepare a release paper to be wound around the outermost layer of the dust-removing pressure-sensitive adhesive tape formed as the roll B. The present invention has been made to solve the above conventional problems.

[0006]

A method for producing a pressure-sensitive adhesive tape for dust removal according to the present invention, and a pressure-sensitive adhesive tape for dust removal, wherein the pressure-sensitive adhesive layer of a pressure-sensitive adhesive tape having a pressure-sensitive adhesive layer provided on one surface of a substrate sheet is placed outside. When the tape is manufactured, a release layer is provided on one surface of the base sheet, an adhesive layer is laminated on the release layer surface, and the adhesive layer surface is wound inside.

The dust-removing pressure-sensitive adhesive tape of the present invention has a release layer provided on one surface of a substrate sheet, and the pressure-sensitive adhesive tape having an adhesive layer laminated on the release layer surface is wound with the pressure-sensitive adhesive layer side facing inward. It is characterized by being taken.

The substrate sheet used in the present invention includes:
A synthetic resin film represented by paper or a biaxially oriented polypropylene film is suitable, and a non-woven fabric or a woven fabric laminated with a polyethylene resin on one side can be mentioned.
As the adhesive layer, a well-known one such as a general-purpose rubber type, acrylic resin type, hot melt type or the like is used. Representative examples of the release layer include organic release agents such as silicone-based and long-chain alkyl group-containing polymers.

As described above, known adhesives, release agents, and coating techniques for these are used. In the present invention, the release layer and the adhesive layer are provided in this order on one surface of the base sheet. The feature is that they are laminated and wound with the adhesive layer inside.

No release agent is applied to the back surface of the base sheet. Therefore, since there is no releasability, the pressure-sensitive adhesive tape wound with the pressure-sensitive adhesive layer on the inside is the back surface of the base sheet immediately below the pressure-sensitive adhesive layer. The adhesive layer is transferred to. When this is unrolled, the base sheet having only the outermost layer without the tacky layer and having only the release layer is unrolled, and thereafter the pressure-sensitive adhesive tape roll with the tacky layer exposed is left on the surface. From the next second round, an adhesive tape having a release layer on one side of the base sheet and an adhesive layer on the back side is fed out.

To use the dust-removing pressure-sensitive adhesive tape of the present invention, first, the base sheet having only the release layer is cut off from the outermost layer, which is the first round, from the second round in the same manner as the conventional dust-removing pressure-sensitive adhesive tape. You can use it. The base sheet cut from the outermost layer can be used as a release paper when storing the dust-removing adhesive tape.

[0012]

Since the release tape is provided on one surface of the substrate sheet and the adhesive tape having the adhesive layer laminated on the release layer surface is wound up with the adhesive layer surface inside, the adhesive layer is directly below the adhesive tape. Transferred to the back of the sheet. Since the adhesive layer is not exposed on the outermost layer of the dust-removing pressure-sensitive adhesive tape formed as a roll, it is not necessary to separately prepare release paper and wind the release paper. After the second lap, a wound body is obtained in which the adhesive layer is exposed to the outside. The cut-out outermost base material sheet can be used as release paper during storage of the dust-removing adhesive tape.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of a method for producing an adhesive tape for dust removal according to the present invention. Base material sheet with release layer 12 made of silicone resin on one side (bleached Kurupack paper basis weight 53g /
m ² , thickness 65 μm) 11 with the release layer 12 on the outer side, while feeding the release layer 12 with the release layer 12 on the upper side,
On the surface of the release layer 12, 70 parts by weight of natural rubber, 30 parts by weight of SBR, 60 parts by weight of tackifying resin (YS resin, trade name "YS resin"), softening agent (trade name "process oil, manufactured by Sun Oil Co., Ltd." Adhesive 14 consisting of 30 parts by weight and 2 parts by weight of an antioxidant (trade name “Yoshinox BHT” manufactured by Yoshitomi Pharmaceutical Co., Ltd.)
To a thickness of 24 μm and then passed through a drier 4 for drying to form an adhesive layer 13 and a dust removing adhesive tape 1
Was wound around the paper tube 5 with the adhesive layer 13 inside to obtain a roll A.

At the end of the first round of the outermost layer of the roll A, a cut 6 is provided in the width direction of the roll A in the axial direction of the paper tube 5 and reaching the paper tube 5 (FIG. 2). This break 6
This is because it is easy to peel off the dust-removing pressure-sensitive adhesive tape 1 on which dust is attached, one by one.

FIG. 2 is a side view of the wound body A of the dust-removing adhesive tape 1 manufactured by the above method, and FIG. 3 is an enlarged view of a portion of FIG. The outermost layer of the dust-removing pressure-sensitive adhesive tape 1 wound around the paper tube 5 is a base material sheet 11, a release layer 12 provided on one side of the base material sheet 11, and an adhesive layer laminated on the release layer 12 surface. Layer 13
Is wound inside.

FIG. 4 is a side view showing a state in which the outermost base material sheet 11 is peeled around the roll A of the dust-removing adhesive tape 1 of FIG. 2 once, and FIG. 5 is an enlarged view of a portion b of FIG. .. The adhesive layer 13 laminated on the outermost base material sheet 11 is transferred to the back surface of the base material sheet 11 immediately thereunder, and only the release layer 12 is laminated and peeled off. The adhesive layer 13 was exposed.

In the above method for producing the dust-removing adhesive tape,
After the application of the pressure-sensitive adhesive, the step of winding the wound body with the pressure-sensitive adhesive layer on the outside while unwinding the roll, and the apparatus therefor were omitted. Since the outermost layer of the obtained roll A of the adhesive tape 1 for dust removal is the base material sheet 11, it is not necessary to separately prepare a release paper, and the outermost base material sheet 11 is peeled off once when used. And it could be used as a conventional dust-removing adhesive tape.
In addition, the base sheet without the outermost adhesive layer peeled off first
11 is convenient because it can be attached to the surface of the pressure-sensitive adhesive layer 11 of the roll A while the dust-removing pressure-sensitive adhesive tape 1 is being stored.

[0018]

EFFECTS OF THE INVENTION Since the present invention has the above-mentioned constitution, the step of rewinding the pressure-sensitive adhesive tape coated with the pressure-sensitive adhesive and rewinding the pressure-sensitive adhesive layer and the device therefor can be omitted, and the manufacturing can be performed efficiently. it can. Further, the dust-removing pressure-sensitive adhesive tape obtained thereby is easy to handle because the pressure-sensitive adhesive layer is not exposed at the outermost layer, and it is not necessary to separately prepare release paper. The base sheet cut out from the outermost layer can be used as a release paper even during storage of the dust-removing adhesive tape.
