JPH04246487A - Self-adhesive tape for dust removal - Google Patents

Abstract

PURPOSE:To easily peel away the outermost layer of which almost the whole of the surface has been covered with dust. CONSTITUTION:In a roll 1 wherein a self-adhesive tape comprising a substrate which has been coated with a self-adhesive layer 11 having a peeling strength of 5-50g/mm width and has a narrow uncoated part 12 along its one side edge has been wound up with the adhesive layer 11 kept outside, a cut 3 in the direction of the axis of a core is formed in full width of the tape. The outermost layer is peeled away without causing longitudinal tearing.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-removing adhesive tape for removing dust, hair, etc. from carpets, clothes, etc.

0002

[Prior Art] It has been known to remove dirt, hair, etc. from carpets, clothes, etc. by attaching them to the adhesive layer of a roll of adhesive tape, which is wound with the adhesive layer on the outside. It is also known to make perforations in the width direction of the adhesive tape in order to peel off and remove dust etc. that adhere to almost the entire surface of the outermost layer (Japanese Utility Model Publication No. 52-3272).
.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned adhesive tape, when peeling off and removing the outermost layer on which dust and the like have adhered to almost the entire surface, multiple sheets may be peeled off at the same time, or perforations may remain uncut. There was a problem that it was easy to tear vertically from the part. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a dust-removing adhesive tape that can easily peel off and remove the outermost layer of the adhesive tape that has lost its adhesive strength.

0004

[Means for Solving the Problems] The present invention leaves a narrow portion along one side edge on one side of the support, and has a peeling force of 5 to 5.
An adhesive layer made of an adhesive with a width of 0 g/25 mm is formed, and a cut in the axial direction of the core is provided at one location over the entire width of the adhesive tape roll, which is wound with the adhesive layer on the outside. Its gist is that

[0005] If the peeling force of the adhesive is less than 5g/25mm width, the outermost layer may peel off when the adhesive tape roll is rolled in contact with a carpet, etc., and the peeling force is less than 50g/25mm. If the width is exceeded, a large force is required to peel off the outermost layer which has lost its adhesive strength.

[0006]

[Function] The adhesive tape for dust removal of the present invention has a
Peeling force is 5-50g, leaving a narrow part along one side edge.
An adhesive layer made of an adhesive with a width of /25 mm is formed, and a cut in the axial direction of the core is provided at one location over the entire width of the adhesive tape roll wound with the adhesive layer on the outside. If you lift the outermost layer of the adhesive tape by picking the narrow part where no adhesive is applied with your fingertips, you can easily peel off the outermost layer of adhesive tape, which has dust etc. adhered to almost the entire surface, and create a new adhesive. The agent layer can be exposed.

[0007]

[Examples] Examples of the present invention will be specifically explained below.
The invention is not limited to the examples. On one side of the support, which is a stretched polypropylene film with a thickness of 50 μm that has been subjected to corona discharge treatment on both sides, a room temperature curing silicone solution is applied and cured to form a release agent layer, and then on the other side, rubber and acrylic are applied. On the undercoat layer coated with a mixture of an acid graft copolymer and an isocyanate compound-based crosslinking agent, a peeling force of 5 to 50 g/25 mm width is left, leaving a narrow portion 12 along one side edge. An adhesive tape having an adhesive layer 11 coated with the rubber-based or acrylic adhesive was obtained.

[0008] The obtained adhesive tape is wound around a paper core 2 with the adhesive layer 11 on the outside, and a cut 3 in the axial direction of the core 2 is provided at one location over the entire width. There is.

[0009]

Effects of the Invention The adhesive tape for dust removal of the present invention is constructed as described above, so by picking up the narrow part along one side edge where there is no adhesive layer with your fingertips and lifting it, you can remove the outermost layer. It is possible to peel off adhesive tape without vertical tearing.
Dust removal work can be done easily.
