The colored paper is then cut into tapes 20-40mm in width, which, in turn, are cylindrically twisted around a core material to form colored paper yarns, which are then further colored and woven, or vice versa, thus obtaining an alternative 'tatami' facing as the objective facing material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a covering material for a flooring material produced by finely cutting paper, twisting the paper to form a textile yarn, and weaving the textile yarn, and a flooring material for the flooring material. The present invention relates to a flooring material using an upholstery material.

[0002]

BACKGROUND ART Flooring materials for houses include flooring, carpets, cushion floors, tatami mats, etc., but tatami mats that are excellent in heat retention, elasticity, and touch in line with Japanese lifestyle are currently being reviewed. .. Therefore, various materials have been proposed as materials for tatami mats, but at present, no suitable material has been found other than grass. However, grass also has various drawbacks. That is, since the fiber diameter and the color are limited due to the natural fiber, there are few design variations. Since it is a natural fiber, it is prone to mite and mold. There is a white sponge-like fiber core inside the grass.
When the surface is worn and white spongy fibers appear, it becomes noticeably unsightly. Natural fibers are easily affected by the weather, and their quality varies greatly. Since natural fibers cannot be obtained in long lengths, the weaving width is limited, and large ones cannot be woven.

A tatami-mat table using a synthetic resin such as polypropylene as a fiber has been proposed to cope with the above-mentioned drawbacks of natural grass, rush, but it has the following drawbacks. Poor hygroscopicity makes it sticky and inferior in touch. Since the material is artificial, it is inferior in natural feeling such as texture and color.

Therefore, attention was paid to paper as a material for the upholstery material for flooring which solves the above problems. As a paper product, conventionally, a woven fabric is known, in which a paper made by papermaking is twisted into a yarn and the weaving yarn is weaved. As an example, "paper having a basis weight of 10 to 60 g / m ² is cut into a width of 5 to 40 mm and twisted to form a fiber, and the fiber is woven to have a density of 200 to 800 g / m ^2. Floor covering material woven with m ² (Japanese Patent Application No. 3-326920)
However, in this case, a natural texture similar to that of grass and an excellent feel can be obtained as compared with polypropylene fabrics, and the conventional applications such as wallpaper, slippers, hats, seat covers, etc. It was possible to improve the abrasion resistance, which is a drawback of the paper fabric used for, but because the yarn is thick and the weaving method is unavoidable due to the nature of the yarn, the surface of the fabric is rather rough. However, there is a problem that it is caught on feet and things, but it is disadvantageous in terms of abrasion resistance even though it is improved, and it is still insufficient to accurately give the texture of rush in terms of color. It was

[0005]

Therefore, the problem to be solved by the present invention is to have a more natural texture and color,
We provide a paper floor covering with excellent touch, good foot and object resistance, excellent abrasion resistance and stain resistance, and stable material supply and quality. And to provide a flooring material that uses this floor covering material.

[0006]

In order to solve the above-mentioned problems of the invention, the first aspect of the upholstery material (2) for flooring of the present invention is as follows. Paper made at 25 g / m ²
(1c) is cut into a width of 20 to 40 mm, twisted into a tubular shape to form a fiber-making yarn (1), and the fiber-forming yarn (1) is weaved ”. .

Under the above-mentioned conditions, when the basis weight is 15 g / m ² or less, the strength of the paper (1c) is too thin, and there is a problem that the practical strength is weak to form the fiber (1).
When the basis weight is 25 g / m ² or more, the paper (1c) is too thick to be twisted into a tubular shape when forming the fiber-making yarn (1). Within the range of the basis weight, a tubular fiber yarn (1) having an appropriate strength can be produced. When the width of the material paper is less than 20 mm, the number of windings is small and the fiber-making yarn (1) is too thin, and when it is 40 mm or more, the number of windings is large and the fiber-making yarn (1) is too thick. Number of turns is 6 to 1
About 6 layers are preferable. The cylindrical twisted yarn (1) is elastic because the center thereof is a hollow (1a) and the periphery thereof has 6 to 16 layers of paper. The paper (1
It is possible to change the hardness of the tubular twisted yarn (1) by changing the number of c) piled up. The present invention, while using an artificial paper (1c), it is possible to bring out a more natural texture and color, and it is possible to exhibit abrasion resistance and hygroscopicity and exhibit excellent touch. In addition, it is possible to provide an upholstery material (2) for flooring which is stable in terms of material supply and quality.

The floor covering material (2) according to claim 2 is the second embodiment, which is a paper sheet (1c) prepared by making paper with a basis weight of 15 to 25 g / m ^2.
It was formed by cutting it to a width of 20-40 mm, twisting it in a tubular shape around the core material (1b) to form a fiber-making yarn (1), and weaving this fiber-making yarn (1). " Characterize things.

By winding up the material paper (1c) around the core material (1b) (for example, cotton thread, woolen thread, etc.) in the same manner as in claim 1, the tubular twisted thread (1) becomes stronger and less likely to be crushed. . If the core material (1b) is hard and strong like cotton thread, tubular twisted thread
(1) becomes stiff, and if a soft and elastic material like wool is used, it will have excellent cushioning properties. Any material (such as wire) can be used as the core material (1b) as long as it is linear. As a result, the fiber-forming yarn (1) for a material having a core can be obtained as compared with the floor covering (2) according to claim 1.

A third aspect of the present invention defines coloring of the floor covering (2) according to the first or second aspect of the present invention, in which "a colored paper (1c) colored at the time of papermaking is used. The yarn (1) was formed, and the secondary colored fiber yarn (1) formed by further coloring the primary colored fiber yarn (1) was used for weaving. ” or,
The same applies to claim 4, "A colored fiber (1c) colored at the time of papermaking is used to form a fiber (1), and the primary colored fiber (1) is used for weaving. It was obtained by further coloring a woven fabric obtained by weaving. ”

Primary coloring is carried out at the stage of papermaking, and secondary coloring is carried out at the fiber-making yarn stage or the woven fabric woven. Even if they are colored with the same color, the colors are subtly different between the primary coloring and the secondary coloring, giving a natural texture. For the primary coloring, the material paper (1c) that has been colored and thinly cut at the papermaking stage is twisted to form a tubular fiber yarn (1), which is woven using this fiber yarn (1). , Weave upholstery material for flooring (2). Since such a floor covering (2) is colored up to the core, even if the inside of the fiber (1) appears due to peeling of the paper (1c) on the surface due to abrasion, discoloration or discoloration occurs. There is little to do. By simultaneously adding a sizing agent and a paper strength enhancer, the water resistance and strength of the fiber (1) can be improved. The textile yarn (1) is secondarily colored, or after spinning, it is secondarily colored. Secondary coloring is performed with the same color as the primary coloring agent added at the fiber making stage, so that the colors are subtly different and a natural texture is given. Further, by changing the color between the primary coloring and the secondary coloring, it is possible to give a design having a change. At the same time, by adding a resin and a water repellent, the fabric is prevented from fraying and twisting, the abrasion resistance and the durability are improved, and the physical properties more suitable for flooring are given.

A fifth aspect of the present invention is a floor material (3) according to any one of the first to fourth aspects, wherein the floor material main body (4) is provided with a floor material upholstery material (2). ] Characterized by that. As a result, it begins to have an excellent natural feeling with respect to texture and color,
It was possible to construct a flooring (3) with a number of characteristics. In addition, unlike natural materials such as rush, these floor coverings (2) consist of industrially produced fiber yarn (1), and there is no limitation on the weaving width, and a wide material can be obtained. It is suitable as a floor material (3).

[0013]

The present invention will be described in detail below with reference to the illustrated embodiments, but the present invention is not limited thereto. As the pulp used in the present invention, wood pulp used in general papermaking is used. (Although not particularly limited, those having relatively long fibers and having balanced tensile strength and elongation are preferable. Specific examples of the pulp used in the present invention include herbaceous pulp such as Manila hemp and sisal hemp. , Or northern softwood such as Northern pine is used. These are characterized by excellent tensile strength.) Papermaking process, papermaking equipment and additives used are the same as in ordinary papermaking operations. .

The sizing agent and the paper strengthening agent as the moisture resistant agent can be selected from those used in ordinary papermaking. Pigments such as red iron oxide, manganese brown, ultramarine blue, and yellow lead are used as colorants, and basic dyes, acid dyes, direct dyes, and the like are used as dyes. Pigments are more resistant to discoloration.

The paper made by the papermaking with a basis weight of 15 to 25 g / m ² is cut into a width of 20 to 40 mm and twisted into a tubular shape to form a fiber. (At this point, the colored yarn can be secondarily colored and coated with a mixture of a lacquer containing a colorant, a resin, and a water repellent.) The thickness of the fiber yarn is about 1 to 2 mm in this embodiment. The size is close to grass. The paper is wound in a loose spiral, and is wound in a tubular shape as shown in FIGS.

The obtained fiber yarn (1) is woven into a fabric having a density of 500.
A woven fabric as the upholstery material (2) for flooring is produced with a tatami-loom loom at 1,500 g / m ² . At this point, the woven fabric may be secondarily color-coated with a lacquer or resin containing a mixture of a colorant and a water repellent. In that case, EVA, vinyl acetate, ethylene vinyl acetate, acrylic, silicone, fluorine, wax, etc. are used alone or in appropriate combination. The coating method may be dipping, spraying, roll transfer, or the like. After coating, heat roll or hot air drying is performed. In addition, the coating agent may be water-based or solvent-based, and the coating / drying process can be performed by a commonly used method.

The woven fabric (2) thus finished can be laid on the floor as it is or used as a tatami mat. However, in order to effectively use it, the following composition is used for the floor material. It can also be used as upholstery material (2). That is, a laminate of an insulation board (5) and a cushion material (6) is used as the floor material body (4), and an adhesive (usually a vinyl acetate emulsion adhesive is used on the surface of the cushion material (6). .) And apply the floor covering (2). The end portion of the floor covering material (2) is wound from the side surface to the bottom surface of the floor material main body (4) and fixed with a tape (7). The sectional view is shown in FIG. It is also possible to use double-sided tape instead of the adhesive.

The structure of the flooring material (3) is not limited to the above-mentioned case, and as the flooring material main body (4) other than the above, plywood, foamed polyethylene resin, urethane resin and insulation board are used alone or in these. A combination or the like is used. The finished floor material (3) can be placed directly on the flooring, for example, or the back surface of the floor material (3) can be fixed by sticking the non-slip tape (7).

(Example 1) Wood pulp having a sizing agent, a coloring agent (pigment) and a paper strengthening agent added thereto had a basis weight of 18
Paper was made so as to have g / m ² . Width of the obtained base paper is 30m
Slit into m tape shape and twist with a tube twisting machine, diameter 1.
A 2 mm tube-twisted Japanese paper thread was used. This was woven with a rapier type automatic tatami weaving machine using a vinylon mixed wire yarn as the warp yarn and the above-mentioned tubular twisted Japanese paper yarn as the weft yarn, and a resin having the following composition was secondarily colored and coated. Resin Fluorine-based resin 1 part by weight Water repellent ethylene vinyl acetate 2 parts by weight Coloring agent Pigment 0.7 parts by weight Water 8 parts by weight

Example 2 The twisted Japanese paper yarn obtained in Example 1 was coated with a resin having the above composition and then woven in the same manner. In each of Examples 1 and 2, the appearance and feel were very similar to those of rush, and the surface was extremely smooth and elastic compared to the conventional tatami mats made from non-cylindrical Japanese paper threads. Yes, it had a more natural texture. Further, there is almost no difference between Examples 1 and 2, and the secondary coloring may be either a fiber-making yarn or after weaving.

EFFECT OF THE INVENTION The floor covering material of the present invention is, as shown in claim 1, 20 to 40 mm of paper made with a basis weight of 15 to 25 g / m ^2.
It is formed by weaving the fiber by cutting it into a width, twisting it into a tubular shape, and weaving this fiber, so the surface is smooth and does not get caught on feet or objects There is little, it feels good on the feet, and it looks smooth. In addition, the papermaking yarn is hollow at the center, and the paper is surrounded by several layers (6-16
It is heavy and has elasticity. By changing the overlap of the paper, it is possible to change the hardness of the tubular twisted yarn, and it is possible to select the elasticity and the hardness which are very similar to those of grass.

The floor covering material according to claim 2 is the same as that according to claim 1.
On the other hand, it is different in that the filament is formed by twisting in a tubular shape around the core material, and the stiffness of the filament is increased and becomes difficult to be crushed. In this case, the type of core material can be appropriately selected from hard ones such as wire and cotton yarn to soft and elastic ones such as woolen yarn. The physical properties can be appropriately selected.

In the floor covering material of claim 3, the colored yarn colored at the time of papermaking is used to form the fiber-forming yarn, and the primary colored fiber-forming yarn is further colored to form the second coloring. The flooring material for flooring according to claim 4, which is formed by weaving using a papermaking yarn, uses a papermaking yarn formed by using colored paper colored at the time of papermaking. It is formed by further weaving the fabric and further coloring the woven fabric obtained by the weaving, and is primary-colored in the papermaking stage and secondary-colored after the fiber-forming yarn or the weaving. By performing the coloring twice as described above, the colors are subtly different between the first color and the second color even with the same color, and it is possible to create a natural texture that is very similar to a more natural grass.

A fifth aspect of the present invention is a flooring material, characterized in that it is formed by tensioning the flooring overhanging material according to any one of the first to fourth aspects on the surface of a flooring body. It is possible to bring out the heat retention, elasticity, excellent tactile sensation, natural texture and color, which are the advantages of grass, and to prevent the occurrence of mites and molds and to freely select the fiber diameter and color to some extent. It can support a wide variety of design variations, and even the core of the thread is of the same quality and color, so it does not stand out even if the surface wears out.
In addition, it was possible to improve the drawbacks of rush, such as excellent water resistance and antifouling property, and it was possible to make a wide variety of grass, and it was possible to make a very excellent flooring material.
