JPH11332602A - Slippers sole silencing and floor protecting tacky adhesive sheet - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a slippers sole silencing and floor protecting tacky adhesive sheet for affixture which suppresses the foot sounds of slippers, protects a floor so as not to flaw the floor and is capable of polishing the floor by walking. SOLUTION: This slippers sole silencing and floor protecting tacky adhesive sheet is formed by sticking a double-sided tacky adhesive layer 2 to the entire surface on one side of a silencing and floor protective sheet 1 of the same shape as the shape of a slippers sole or a shape slightly smaller than this shape and covering the entire front surface thereof with a release paper 3. The silencing and floor protective sheet 1 in the form of the heel portion alone of the slippers sole is equally well. A thick-gaged span board nonwoven fabric which is made by entanglement of fine long fibers, is porous and cushiony, does not unravel the ends in spite of blanking with a Thompson die, has excellent wear resistance and dimensional stability, has the softness of the fibers and is low in cost is optimum as the blank for the silencing and floor protective sheet 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound-deadening / floor protection adhesive sheet which is attached to the back bottom of a slipper and used for sound-deadening / floor protection.

[0002]

2. Description of the Related Art In a conventional slipper, its back bottom is sewn to a slipper body by covering a core plate with vinyl leather, synthetic leather or the like.

[0003]

With conventional slippers, the material of the back bottom is a flat vinyl leather sheet, which is relatively hard and has low sound absorption and cushioning properties. When walking on a hard floor, there was a problem that the floors made of rattling and rattling were noisy, and small scratches were easily made on the floor of the wood and the flooring.

[0004] It is an object of the present invention to provide a sound-absorbing / floor-protecting pressure-sensitive adhesive sheet which is attached to a slipper to reduce footsteps and protect the floor without damaging it.

[0005]

In order to achieve the above object, the sound-absorbing / floor-protecting pressure-sensitive adhesive sheet of the present invention pays particular attention to the characteristics of a thick spun-bonded nonwoven fabric, and converts it to the entire back bottom of the slipper. It is also possible to form only the heel part, making it the same or slightly smaller to form a sound-absorbing / floor protection sheet (1), sticking a double-sided adhesive layer (2) on one side of the entire surface, and further on the entire surface Covered with a release paper (3).

[0006] A sound-absorbing / floor protection sheet used in the present invention (1)
The material is most preferably a thick spunbonded nonwoven fabric, but any material having a porous or brushed cushioning property, such as a brushed fiber such as felt, needle punch, velvet, or fur, or urethane, may be used.

The double-sided pressure-sensitive adhesive layer (2) is formed of a double-sided pressure-sensitive adhesive sheet or an adhesive such as vinyl acetate or acrylic, and the release paper (3) covering and covering it is made of silicon-treated flat paper. preferable.

[0008]

In the sound-absorbing / floor-protecting pressure-sensitive adhesive sheet constructed as described above, the release paper (3) for protecting the double-sided pressure-sensitive adhesive layer (2) from sticking to an external object so that the pressure-sensitive adhesive does not stick to the paper. Since it has been subjected to a silicon treatment or the like, it can be easily peeled off by hand to expose the double-sided adhesive layer (2). The entirety of the invention can be attached to the slipper back bottom with the double-sided adhesive layer (2).

[0009] When walking on a hard floor such as a flooring floor, a porous material made of thin long fibers of a thick spunbonded nonwoven fabric, which is a material of the sound-absorbing / floor protection sheet (1), has sound absorption and cushioning properties. Absorbs the sound of slippers hitting the floor.

In addition, since the material is made of fiber and soft, the floor is not hurt even when walking, and the floor is polished while walking.

[0011]

Embodiments will be described with reference to the drawings.
In FIG. 1, the sound-absorbing / floor protection sheet (1)
An existing double-sided pressure-sensitive adhesive sheet is laminated to provide a double-sided pressure-sensitive adhesive layer (2) and a release paper (3), or a pressure-sensitive adhesive is applied to provide a double-sided pressure-sensitive adhesive layer (2), and a release paper (3 ), Or by making a laminated sheet by either method, and punching it out with a Thomson mold, which is the same as or slightly smaller than the back bottom of the slipper. In recent years, it can also be cut by a laser beam.

In the embodiment shown in FIG. 2, a Thomson-type sole of the heel, which weighs the heaviest on the sole of the back of the slipper and produces the sound of striking the floor, is punched out.

[0013] As a material of the muffling / floor protection sheet (1),
Thick spunbond nonwoven fabric is most suitable because it is made of thin long fibers entangled, so it is porous and has cushioning properties.
This is because it has excellent dimensional stability, has softness of the fiber, and is inexpensive. Brushed fibers such as felt, needle punch, velvet, and fur having similar characteristics, or urethane may be used, but the cost is high.

In general, double-sided adhesive processing is performed by using a thin film or paper as a base material, applying an adhesive on both sides thereof, and covering an existing double-sided adhesive sheet covered with release paper on a sound-absorbing / floor protection sheet (1). It is common to crimp to vinyl acetate,
An adhesive such as an acrylic adhesive may be applied to the entire surface of one side of the muffling / floor protection sheet (1), and the entire surface of one side of the release paper may be covered with release paper that has been subjected to release treatment such as silicon treatment.

[0015]

Since the present invention is configured as described above, it has the following effects.

Simply peeling off the release paper (3) and attaching it to the back bottom of the slipper with the double-sided adhesive layer (2) has the effect of being easily mounted.

The material of the sound-absorbing / floor protection sheet (1)
Since the thick spunbonded nonwoven fabric is a porous and cushioning soft fiber, it has a noise-reducing effect of slippers, a floor-protecting effect that does not damage the floor, and a cushioning-like comfortable effect.

Further, since the material is fiber, simply by walking with the slipper equipped with the present invention, there is an effect of polishing the floor.

Further, since the material is entangled with thin long fibers, the cut ends do not fray without sewing.
There is an effect that fluff and fibers do not fall off, so that there is an effect that processing can be performed without much trouble and cost can be reduced.
