Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a wall covering material that is novel and has a natural feel that has never been seen before.

[Conventional technology] Wall covering materials, which have traditionally been used to improve aesthetics, have been placed with emphasis on having relatively simple hues and patterns, from the perspective of being part of decorations. He has been taken care of.

However, with the recent diverse developments in the fashion industry, housing industry, and materials industry, not only are the required characteristics such as hue and pattern required, but also surface roughness, smoothness, unevenness, unexpected roughness, new material properties, etc. Fashion and aesthetic factors have also come to be considered important.

Based on this point of view, when considering textiles, for example, dyeing and embroidery are methods for changing the color and pattern, and methods for creating an uneven effect on the surface include shrinkage treatment and embossing. There are molding processes such as

Furthermore, in order to make the surface uniform, measures such as coating the surface of the fabric with resin have been taken.

As mentioned above, there are various methods of creating three-dimensional patterns on the surface of fabric to impart aesthetic and fashion effects, and each of these has unique characteristics and can be said to have formed their own product fields. However, in all cases, the size of the pattern is limited, the same pattern is monotonously repeated, and the characteristics of interest, surprise, and new materials do not meet recent demands for diversification.

That is, when trying to create a three-dimensional uneven pattern on the surface of a fabric, methods such as embossing the surface of the fabric or applying chemical treatment using a transfer roll are used.
All of these means have the drawback that the same pattern is repeated over and over again with each cycle of the mold or roll.

In general, the uneven patterns obtained by these methods are artificial and lack a natural feel due to the means of pressurization or chemical treatment, or corrosion.
Wall covering materials, especially fashionable effects not found in conventional products,
Even when used as an interior wall material that has a great aesthetic effect,
There are only 1q of effects.

[Problems to be Solved by the Invention] The purpose of the present invention is to create a new three-dimensional pattern on the surface of a fabric that has not been seen before, unlike the three-dimensional pattern on the surface of the fabric formed by the above-mentioned conventional technology. It is made of a fabric with unique patterns, and aims to provide a new type of wall covering material with new material properties and unexpectedness.

[Means for Solving the Problems] The novel wall covering material of the present invention that achieves the above-mentioned objects has the following configuration.

In other words, the novel wall covering material of the present invention has a scale-like structure in which a large number of raised ends are gathered together to form a substantially integrated scale-like structure, and the scale-like 4F4 structure covers the surface layer of the fabric. This wall covering material is characterized by using a large number of three-dimensional fabrics covering the wall.

[Effect] The present invention will be explained in more detail.

In the present invention, the wall covering material refers to the following materials.

That is, they include wall materials for rooms, halls, etc., exterior wall materials for buildings, various structures, etc., and interior materials for vehicles such as automobiles and trains.

FIG. 1 is a schematic diagram of an interior wall material for a room showing an example of a wall covering material according to the present invention.

This is a part of the interior wall covering material 1 of the room shown in FIG. 2 consists of a three-dimensional cloth, which will be described later, and the other part 3 is a commonly used printed cloth, etc., and this is a schematic illustration of how the two are arranged alternately to form the inner wall of a room. be. The three-dimensional fabric used in the novel wall covering material of the present invention has a scale-like structure in which a large number of raised ends are gathered together and substantially integrated to form a flat structure. A large number of scale-like structures exist covering the surface layer of the fabric.

FIG. 2 is a schematic model plan view partially showing the surface of such three-dimensional fabric.

As shown in FIG. 2, on the surface of the three-dimensional fabric 4, a scale-like structure 5 formed by forming a surface by substantially integrally flattening the ends of a large number of raised naps 411M1 is formed through cracks 6. A large number of them are arranged adjacent to each other.

FIG. 3 shows an example of the cross-sectional structure of such a three-dimensional fabric, and is a schematic cross-sectional view of a model without showing the cross section of FIG. 2 AA.

As shown in FIG. 3, the three-dimensional fabric 4 has a three-layer structure. a1
A scale-like structure 5 formed by self-adhesive and flattened to form a surface 8 due to the heat-melting properties of the polymer constituting 1N.
A large number of the scale-like structures 5 are arranged through cracks 6 so as to cover the surface layer of the three-dimensional fabric.

Although the scale-like structures 5 that are in contact with each other are separated in surface appearance by the cracks 6, they are actually connected inside the fabric via the napped fibers 7, the base 511, and different napped fibers 7. That is, a large number of napped fibers 7 existing between the scale-like structure 5 and the base fabric 11 usually maintain a napped fiber-like forest state and form a large number of napped aggregates 9, forming a middle layer with a high porosity. Two napped fiber layers 10 are formed. The third layer, which is the lowest layer, is a base fabric 11, which holds the napped fibers and forms the base of the three-dimensional fabric 4.

Since the three-dimensional fabric 4 used in the wall covering material of the present invention has the configuration shown in FIGS. and group 15
Although they are connected by separate napped fibers 7 through 11, they are separated by cracks 6, and the individual scale-like structures 5 form an aggregate of scale-like structures that can move independently. Due to its structure, it has a unique three-dimensional pattern and appearance. ? It has a special shape. Due to this special shape, when viewed from various directions, black-dyed items in particular may have a different color when wet, or may look like bagworms, the bark of pine trees, etc.
It can create a unique and new appearance that has never been seen before, such as reptilian epidermis-like appearance, or mineral-like appearance, such as coal or mica, and a glossy appearance.

Such a three-dimensional fabric can constitute a wall covering material with excellent heat retention due to the synergistic effect of the planar scale-like structure of the surface layer and the nap layer with high porosity of the inner layer. Despite the impression it gives, it has a light weight and can be used as a wall covering material.

The three-dimensional fabric used for the novel wall covering material of the present invention preferably has a basis weight within the range of 80 to 900q/Tr12, and the length of the standing pile in the forest-like standing pile layer in the middle layer is 1 to 900q/Tr12. It is preferably within a range of about 4Qmm.

The three-dimensional fabric used in the present invention can be manufactured based on a raised fabric, and the raised fabric has a basic base material.
For example, double velvet weaving such as single pile or double pile, dencil weaving, chenille yarn-based woven and knitted fabrics, napped tricot, other warp knitted napped products, electric flocking, mechanical flocking, etc. However, the material is not necessarily limited to these, and any type of raised material may be used. The three-dimensional fabric used in the wall covering material of the present invention is made by using the above-mentioned raw material nuffed fabric and subjecting the napped side to high temperature heat treatment under roller pressure, for example, so that the tip of the napped layer is formed into an Ih fabric on the surface of the napped layer. It can be manufactured by integrally bonding the entire surface, then rolling the fabric, and dividing the integral bonded structure on the entire surface into a large number of fine scales. .

The three-dimensional fabric produced in this way has a natural and rustic feel in which the linear shapes of the many scale-like structures have virtually no fixed shape. It is aesthetically pleasing and desirable.

The length of the nap of the fibers added to the raw nap fabric influences the formation of a scale-like structure. In other words, if the napped length is long, the napped fibers are bent at the waist and can maintain a nearly parallel state along the surface of the base fabric. A continuous plane can be formed, and this plane can be cracked by means such as those described below to form a large number of scale-like structures.
It is qru.

If the length of the raised hair $1iN is too short, it will be difficult to bend it at the waist and it will be difficult to form a scale-like structure with a large area.From this point of view, it is preferable that the length of the raised hair is 3 mm or more, and it is more Preferably, it is 5 mm or more.

The single yarn fineness of the napped fibers is not particularly limited, but when considering the ability to form a scale-like structure, durability, aesthetic appearance, etc., it is 1.
It is preferable to use ultrafine artificial fibers of denier or less, more preferably 0.5 deniers or less. In other words, it is more advantageous to use ultrafine fibers, which have a larger number of raised fibers, in order to arrange a plurality of fibers in parallel and form an integral flat shape.

The area of one scale constituent unit of the scale-like structure is determined by the number of napped fibers forming the scale-like structure, but the average value is 0.5 x 10-2 cm (0°5 mm square)
It is preferably about 1X1X102CIA (10 squares), more preferably about 2X10ai to 1X10CI
It is A.

For example, for very small scale structures, 0,5x
If the range of 10-2ci to 6X10-27 is a medium-sized scale-like structure, 6X10-2cIi to 1X10i
If there is a large scale-like structure within the range, 1x10C
It is preferably within the range of 11 to 102C11.

Incidentally, the area average value V of one constituent unit of the scale-like structure can be determined, for example, by counting the number of scale-like structures in a unit area of 100 cII and using the following equation (1).

V=100ci/I! i Number of flaky structures...
・(1) According to the findings of the present inventors, those having the above-mentioned area range do not have a fixed shape and are mixed as a large number of scale-like structures with moderately random sizes and random shapes. If so, it can constitute a unique wall covering material that has a more natural feel and is also excellent in aesthetics and fashion.

In other words, the area average value of one constituent unit of the scale-like structure is 0.
If it is less than 5 x 1 CV2ci, the scale-like appearance will be small, and if it exceeds 10'' Cl7t, it will have an almost flat appearance, and the paper-like feeling will be strong, and the aesthetics and fashionability will be poor.

On the other hand, although the cracks that form the scale-like structure separate the surfaces of adjacent scales, the adjacent scales are connected to each other via the base fabric by the napped fibers as described above. Therefore, there is no need to pay much attention to the size of cracks or the fineness of their existence.

The material for the three-dimensional fabric used in the novel wall covering material of the present invention may be either natural fiber or synthetic fiber.
These materials may be blended, blended, or mixed as appropriate. However, it is preferable that the fibers forming the raised portion be heat-fusible fibers, especially synthetic fibers! It is preferable to use a textile. Examples of materials for synthetic i-fibers include polyethylene terephthalate or a copolymer thereof (for example, a copolymer component such as 5-sodium sulfoisophthalate), polybutylene terephthalate or a copolymer thereof, nylon 66, nylon 6. Polyamide-based polymers such as No. 12, polyacrylonitrile-based polymers, and the like are preferably used. In addition, it is also preferable to use modifiers and additives blended with these polymers for the purpose of preventing static electricity, improving dyeability, matting, antifouling, flame retardancy, anti-shrinkage, and the like.

Further, the three-dimensional fabric may be appropriately subjected to a process to impart water polishing properties, a process to impart flammability, a process to impart antifouling properties, and the like.

The above-mentioned thermal melting method is preferably used as a method for forming a continuous flat surface of a large number of raised hairs 1 and a miscellaneous group to form a scale-like structure, and the method of fixing with a resin is preferable. is preferably used. Specifically, a method that utilizes the heat-melting properties of napped fibers by applying heat treatment under pressure is a method that improves the durability of the scale-like structure, surface gloss, luxury, three-dimensional appearance, workability, etc. Most preferred.

Even in the case of immobilization with a resin, it is preferable to carry out the above-mentioned method utilizing thermal meltability as a preliminary treatment.

A typical example of heat treatment under pressure is pressure treatment using a calender roll maintained in a heated state.

The heating temperature in this calender roll treatment method should be selected appropriately depending on the material of the napped fibers, but is generally in the range of 120'C to 230°C, preferably 160'C to 210°C. A range of C is preferable, and it is preferable to carry out the treatment at a temperature at which the napped fiber reaches a semi-molten state.According to the findings of the present inventors, the treatment pressure is 5KFj.
/cIIt or more is appropriate, more preferably 20KI/ctA or more, usually 20.~100! j／
It is common to treat within the ctA range.

Scaly fs' as mentioned above? The size of one constituent unit of i can be adjusted by appropriately adjusting the nap state of the fabric before hot pressing and the direction of hair treatment. For example, if the area average value of one constituent unit of the scale-like structure is 0 , 5 X 10-
In order to obtain smaller ones of about 2 ct'-6 x 10-2 cA, brushing and treatment with a finishing agent such as silicone will improve the roughness and smoothness of the raised hair, and then apply it at a slightly lower temperature and in the direction of the raised hair. It is sufficient to heat and pressurize the sea urchin in the direction of hair growth, and then perform a rolling process.

In addition, the area average value of one constituent unit of the scale-like structure is 6×10
- If you are trying to obtain a medium-sized pattern of 2 cm or more or a large-sized surface, heat the material that has a rough texture or is poorly curled at a high temperature, and the direction of the nap is in the opposite direction. Pressure treatment may be performed, and then rolling processing may be performed.

Also, - the area of the structural unit is 0.5x10"ci ~ 1x1
02cIIiPi! If you want to obtain a mixture of small, medium, and large shapes within the range of degrees, you can obtain it by processing the product under the latter conditions and rolling it in a subsequent step.

Furthermore, when it is desired to obtain a three-dimensional fabric having a large number of scale-like structures of substantially regular shape, it is possible to form arbitrary shapes such as triangles, rectangles, polygons, circles, and ellipses using a knife with edges, etc. The surface layer, which is integrally bonded on both sides in one or mixed shapes and/or arbitrary sizes, can be divided into 1q pieces.

The scale-like structure obtained by 1q as described above can be further firmly fixed by resin processing, if necessary, in order to improve shape retention and durability.
It can provide semi-permanent durability.

Examples of the resins used include acrylic, melamine, vinyl acetate, Epoquine resins, and polymeric elastomers such as their covalent tetrapolymers, butadiene copolymers, vinyl chloride copolymers, and polyurethanes. Preferred methods for applying the resin include, but are not limited to, resin impregnation→squeezing→drying→curing, and coating methods such as direct transfer, gravure, and spraying.

The three-dimensional fabric used in the wall covering material of the present invention prepared as described above generally has a large number of scale-like structures with scale flow in a substantially constant direction according to the direction of the nap of the raw stone standing fabric. Exist and become. In the wall covering material of the present invention, it is desirable that the three-dimensional fabric be used so that the flow direction of the scales and the vertical flow direction of the wall covering material substantially match.

The three-dimensional fabric used in the wall covering material of the present invention is processed by coating the back side, scouring the drawing method, etc. in the same way as ordinary napped woven or knitted fabrics in the pre- or post-process of forming a scale-like structure.
It goes without saying that when ultra-fine artificial fibers are used as heat-set processing, napped material, etc., processes such as ultra-fine treatment, dyeing, application of a finishing agent, drying, etc. may be carried out as appropriate.

The novel wall covering material of the present invention uses the three-dimensional fabric prepared as described above as the front side, cuts it, and lining it.It has various characteristics of the raised fabric, and is suitable for wall coverings. It exhibits excellent characteristics as a material.
