Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides tufted carpets, needle punch carpets, and other various textile products for use as interior rugs, interior wall protection, etc. in buildings, houses, ships, aircraft, vehicles, and elevators. The present invention relates to a sheet-like structure that can be constructed very easily and reliably when used as a material.

(Prior Art) Hitherto, tufted carpets, needle bunch carpets, and various other textile products have been used as interior materials such as carpets and inner wall protections in buildings, houses, ships, aircraft, vehicles, and elevators. A strong adhesive is then applied to those textile products.

Paste it on the floor or interior wall, or apply strong adhesive to the floor or interior wall and paste various textile products.

It was attached to the floor, interior walls, etc.

Or use double-sided tape on those textile products to
They were pasted on interior walls or installed on floors without using adhesives.

(Problems to be Solved by the Invention) However, in the conventional W construction method using adhesive or double-sided tape, if pasting fails during construction, it is necessary to peel off and paste again, so construction is not easy. This was time-consuming, costly, and often resulted in poor aesthetics.

In addition, if the floor surface is laid without using an adhesive, the fiber products may shift over time and create gaps, which often require repair.

(Means for Solving the Problems) The present inventors have discovered the difficulty of the conventional construction method for interior decoration materials, and in particular, the difficulty of installing interior materials on the floor surface without using an adhesive. In order to solve the problems of misalignment and spoiling the aesthetic appearance, as a result of various studies, we have discovered a sheet-like side piece that is rational, economical, and aesthetically pleasing, and have arrived at the present invention.

The present invention comprises a base (A) made of a textile product, an adhesive layer (B),
A sheet-like structure formed by laminating a backing fabric (C) with voids in this order, the adhesive strength of the back side being pole tack l (angle of 5 degrees) to 20 (angle of 30 degrees). By making these sheet-like structures into buildings,
When used as interior materials such as rugs and inner wall protection in houses, ships, aircraft, vehicles, and elevators, conventional drawbacks have been solved.

The present invention will be explained in detail below.

The substrates (A) of the various textile products used in the present invention include those conventionally used as interior materials such as rugs and inner wall protection in buildings, houses, ships, aircraft, vehicles, and elevators, such as mats, carpets, etc. , materials with pile-like protrusions such as jutan, and materials without pile-like protrusions such as woven fabrics, needle bunch carpets, and non-woven fabrics.The materials themselves are soft and fashionable, and are suitable for interior decoration. It can withstand use as a material.

In addition, the substrate (A) of these various textile products includes those coated with a binder such as rubber latex on the back surface, or those to which a layer of elastic material such as a foam structure, rubber, or urethane is attached. It can be used even if

Next, as the adhesive layer (B) used in the present invention, adhesiveness is imparted to the back side of various ordinary textile products (A), and the adhesiveness after attaching the backing fabric (C) is The adhesive layer (B) may be of any adhesive type, such as solvent-based, aqueous emulsion-based, hot-melt-based, or other materials, as long as it is satisfactory.

Specifically, solvent-based adhesives such as natural rubber and acrylic resin,
Alternatively, hot melt adhesives, natural rubber and synthetic rubber latexes, acrylic emulsions, synthetic rubber latex aqueous emulsion adhesives, and silicone adhesives can be used.

The thickness of the adhesive layer is preferably 1 Oum to 200 μm
If the thickness of these adhesive layers is too small, it will be difficult to obtain the required adhesion to the adherend, and if the thickness is too large, it will be unsatisfactory in terms of cost.

The backing fabric (C) used in the present invention has voids.

Furthermore, the thickness is lOum ~ 3mm, preferably 20umx
1mm can be used.

If the thickness of the backing fabric (C) is less than ioam, the floor or wall surface will become extremely dirty when the sheet-like structure of the present invention is used, and if it exceeds 3 mm, the adhesive strength to the adherend will be insufficient. is difficult to obtain.

The material of the lining fabric (C) may be any cloth-like or net-like material such as natural or synthetic fibers, valves, metals, wood, resins, etc., and its manufacturing method may include spinning, melting, bonding, film formation, lamination, etc. Depends on the method.

Fabrics, knits, felts, non-woven fabrics, needle-bunched paper, films, and metal foils made by these methods are preferable, and are flexible as long as they have voids. Generally, woven fabrics, knitted fabrics, dry-processed or wet-processed nonwoven fabrics, spunbond nonwoven fabrics, etc. can be used.

Although the shape of the void may be any shape, it is preferable that the shape satisfies the void ratio r defined below.

The void ratio r is preferably in the range of 10-''<r<10', and more preferably in the range of 10''<r<IQ''. The material is irradiated with light from the Z-axis direction to the XY plane, and in the projected view, the area of the part through which the light passes is measured as the void area, and the area of the part where the light is blocked and becomes a shadow is measured as the non-void part, Find the void ratio r.This void ratio r has a very large effect on the adhesion of the sheet-like structure of the present invention to the adherend.If the void ratio is smaller than 10-t, there is not enough adherend. Difficult to obtain adhesion to the adhesive layer (B). If it is greater than 10', the floor or wall surface is significantly contaminated or damaged by the adhesive layer (B).
The void portion may be manufactured in advance to have a predetermined void ratio, or may be adjusted to a predetermined void ratio by drilling, filling, or the like.

The adhesion strength on the CJ side of the above sheet-like structure with voids is determined by pole tack 1 (angle of 5 degrees) to pole tack 20 (angle of 30 degrees), Preferably, the pole tack is between 1 (angle of 5 degrees) and 10 (angle of 30 degrees). If the pole tack is smaller than 1 (angle of 5 degrees), the adhesion to the adherend will be poor, and if it is larger than 20 (angle of 30 degrees), the adhesion to the adherend will be poor. The adhesion to the adherend becomes excessive, which is undesirable.

A sheet-like structure using the above-described textile product can be used as an interior material, such as a rug inside a building, a house, a ship, an aircraft, a vehicle, or an elevator, or as an interior wall protector.
