Abstract

PURPOSE:To product well-regulated and beautiful floor and to make joint at the edge part unclear by driving piles in a diagonally rocking and meandering direction against the direction of tuft of the tufted carpet. CONSTITUTION:Each pile P is driven in the longitudinal direction alpha of the carpet; wherein, a pile is driven at the diagonally front point from the previous one so that the row of piles rocks and meanders; the adjoining pile P is also driven in the same way at the approximately same interval in succession. The rocking distance V of meandering is arranged so as to be in the range of 1/4 to 7/4 of the distance K of the adjoining two rows of piles in the direction of the right angle with the longitudinal direction alpha. As the result, wasteful abundant use of the back pile 5 can be avoided, making the joint point C unclear at the same time. Further, in the tile carpet obtained by cutting the tufted carpet, the density of pile P at the joint point C retains more uniformity compared to the conventional carpet even when the cutting is made very close to the pile P, making the joint point unclear to such a degree that it is not recognized as a distinct line to the eye.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile carpet, and more particularly to a tile carpet which prevents uneven joints between adjacent tile carpets when the tile carpets are spread. is there.

[0002]

2. Description of the Related Art Tile carpets are manufactured, for example, by Kokoku Sho
No. 7172, the triangle described in Japanese Utility Model Publication No. 35-1
The special shape described in Japanese Patent No. 5045 is also known, but generally, a square or rectangular shape is often used, and among them, a substantially square shape of 50 cm ² is often used.

The tile carpet is obtained by manufacturing a large tufted carpet and cutting the carpet into squares or rectangles, which is easy to carry and construct, has a dignified appearance, has a good feeling of stepping, and has a local part. It has an excellent feature that it can be partially replaced when it becomes dirty or damaged,
It is used as a floor material for office buildings. 4 to 6 are a partial schematic plan view and a vertical sectional view showing a form of a conventional tile carpet.

In each figure, α is a tuft direction (hereinafter referred to as a vertical direction), β is a perpendicular direction orthogonal to the tuft direction (hereinafter referred to as a lateral direction), P is a pile, 1 is a pile bulky portion, and 2 is a pile. The focusing part, 3 is a base cloth, 4 is a laminating part, and 5 is a back pile. K is a distance between adjacent pile rows, and S is a distance between pile driving units, that is, a pile interval. X and Y are adjacent tile carpet fragments (tile carpet), and C is the contact point between tile carpets X and Y. The contact point C is the same as the cutting position when a large tufted carpet is cut into a tile carpet.

A conventional tufted carpet is shown in FIG.
As shown in FIG. 5, the pile intervals S in the vertical direction α are arranged in a regular line, and the pile row distances K in the vertical direction in the horizontal direction β are also arranged in a regular line. The cutting position of the tile carpet obtained by cutting such tufted carpet is made in the immediate vicinity of the pile P, and when it is adjacent, as shown in FIG. 5, the contact point between the fragments X and Y is obtained. The pile P in the vicinity of C becomes extremely dense and has a problem of forming one dense line. On the other hand, when the tile carpet obtained by cutting the tufted carpet shown in FIG. 4 is cut farthest from the pile P and it is adjacent to the pile P, the pieces X and Y are cut as shown in FIG. The pile P in the vicinity of the contact point C with and becomes coarse, and there is a problem that one line with a small amount of pile is formed.

That is, when obtaining a tile carpet,
In consideration of the efficiency of the cutting work, a method of collectively punching the piled tufted carpets with a cutting machine is generally used. Since tiles are cut regardless of the pile position in this way, the joints become uneven when the carpets are butt-laid and spread, and especially in tile carpets with low pile weight, there is a problem that the gaps in the joints cause uneven appearance. Therefore, the pile density is unnecessarily increased, and the bulkiness of the pile is increased. However, in each case, a large amount of useless raw yarn is used.

Therefore, in any case, the effect of not only increasing the raw material cost and lowering the productivity but also obscuring the joints commensurate with the increased cost is not satisfactory. It was

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of conventional tile carpets, achieve a tidy and beautiful floor when laid on the floor, and make the joints at the edges inconspicuous. It is to provide the tile carpet made.

[0009]

Means for Solving the Problems The present invention is (1) a tile carpet cut from a tufted carpet into polygonal fragments, the pile driving of which is oblique with respect to the tuft direction of the tufted carpet. It is characterized by a tile carpet that oscillates in a certain direction.

(2) Further, in the above construction, the swinging distance of the pile driving position in the direction orthogonal to the tuft direction is ¼ to 7/4 of the distance K between adjacent pile rows.
It is characterized by being within the range of.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As the pile material of the tile carpet according to the present invention, synthetic fibers formed of thermoplastic polymer such as polyamide, polyester, polyolefin are preferably used. Among them, polyamide-based nylon 6 is particularly preferable. In addition, it is excellent in dyeability, easy to dye in the form of a wide carpet, has good productivity, and has excellent nap properties and abrasion resistance, and thus is particularly preferably used.

1 to 3 are a partial schematic plan view and a vertical sectional view showing a form of a tile carpet according to the present invention.
Α, β, K, S, X, Y, and C in each figure have the same meanings as in the case of the conventional example described above. In the tufted carpet which is the material of the tile carpet of the present invention, each pile P is driven toward the longitudinal direction α of the carpet as shown in FIG. 1, but in that case, it is driven obliquely forward and swings and meanders. There is. This meandering driving is also performed on the adjacent piles P in the same manner, and the piles P are sequentially driven at a substantially equal interval.

The swing distance V of the meander is in the range of 1/4 to 7/4 of the distance K between adjacent pile rows in the tuft direction, that is, in the direction perpendicular to the longitudinal direction α of the carpet. . If it is smaller than 1/4 of the distance K between the pile rows, the difference from the conventional one in which the pile is directly driven is not clear. On the other hand, when the distance between pile rows K is larger than 7/4, the pile rows approach not only the adjacent pile row but also the pile row further ahead,
Is substantially the same as 4/4, and there is a drawback in that a large amount of crimp yarn is required for the back pile 5. Therefore, the meandering swinging distance V of the pile P is set to 1/4 to 7/4, preferably 1/3 to 2/3 of the distance K between the pile rows, so that the contact C is made inconspicuous and the back pile 5 does not stand out.
It is possible to avoid uselessly using a large amount.

The tile carpet obtained by cutting the tufted carpet shown in FIG. 1 has the density of the pile P at the contact point C as shown in FIG. 2 even when the cutting position is made in the immediate vicinity of the pile P. Is a little larger than the other parts, but substantially eliminates the disadvantage of forming a dark line with no density difference compared to the conventional one shown in FIG. 5, to the extent that it cannot be visually recognized as a line. Can be

On the other hand, even when the cutting position of the tufted carpet shown in FIG. 1 is located farthest from the pile P, the density of the pile P at the contact point C is slightly rougher than the other portions as shown in FIG. However, it is possible to eliminate the drawback of forming one line in which the density P is small and the pile P is small compared to the conventional one shown in FIG. 6, and the line is not clearly recognized as a line. it can.

2 and 3 show the tile carpet in the case where the cut position of the tufted carpet is the worst combination. However, even in such a worst combination, the tile carpet according to the present invention remarkably reduces the variation in the joint gap due to the uneven cutting that is inevitable when the tufted carpet is cut at any position. Can be done and the basis weight is 700 g /
Even with a tile carpet of m ² or less, a sufficiently satisfactory, orderly and elegant floor can be expressed.

The tile carpet according to the present invention comprises, for example, polyamide in some or all of the fibers forming the pile.
When a so-called spun yarn in which a pigment is contained in a thermoplastic polymer such as polyester or polyolefin is used, it has good light resistance and is more preferably used in a place exposed to direct sunlight or illumination light. When a so-called antistatic yarn having a low electric resistance is used for a part or all of the pile or the base cloth or the laminate material of the tile carpet according to the present invention, or a substance having an antistatic effect is added, the chargeability is relaxed, and It goes without saying that it is convenient for a dust-free room or the like.

The base cloth and laminate material of the tile carpet according to the present invention are not particularly limited, but materials having small dimensional change with changes in temperature and humidity are preferable, and materials having appropriate elasticity and durability are suitable. ing. It is preferable that the pile, the base cloth, and the laminate material forming the tile carpet according to the present invention are made of chemically similar materials because recycling is easy.

In the tile carpet according to the present invention, the pile driving position in the horizontal direction β is set to the vertical direction α.
The tile carpet of the standard having a large pile interval S in the vertical direction α is more difficult to notice the joints, which is more preferable. As a method of swinging the driving position of the pile in the vertical direction in the horizontal direction,
Any of a method of swinging the needle row in the lateral direction, a method of swinging the base cloth in the lateral direction, or a combination thereof may be used.

As a method of swinging the pile driving position in the lateral direction β, a tuft device in which two rows of needles are arranged in the tuft direction is used. By satisfying the above relationship, it is possible to arbitrarily and preferably displace. L = nS ± mS However, the integer of n: 1-10 m: 1 / 4-1 / 2 Moreover, in the tile carpet of this invention, the bulky part of a pile expands that a pile is mainly a modified cross-section thread. This is preferable because the joint gap can be further reduced. More preferably, the pile is mainly a modified hollow cross-section yarn because the bulky portion of the pile can be further expanded and the joint gap can be further reduced. Further, in the tile carpet of the present invention, it is preferable that the pile is mainly crimped yarn because the bulky portion of the pile is enlarged and the joint gap can be further reduced.

【Example】

Examples 1 and 2, Comparative Example 1 Nylon 6 crimped fibers dyeable with anionic dye, nylon 6 crimped fibers dyeable with a cationic dye, polyester crimped fibers containing a pigment, and core-sheath antistatic yarn. A 2500 denier crimped yarn made by mixing
mm needles are arranged in two rows at 6.35 mm intervals in the longitudinal direction, and the needle rows can be oscillated at any distance in the lateral direction by using a level loop tuft machine. After tufting so that the distance K is 2.54 mm, the pile interval S in the vertical pile row is 2.54 mm, the pile height is 3 mm, and the pile areal weight is 570 g / m ² , the anion dye is applied using a Wins dyeing machine. It was dyed with a mixed dye of a cationic dye, washed with water, dried, laminated with a pinyl chloride resin, and cut into a square of 50 cm on each side to obtain a tile carpet.

In the above tuft, the swing distance V is 1.27 mm in the first embodiment, and the swing distance V is 0.64 m in the second embodiment.
In Comparative Example 1, the rocking distance V was 0 mm, that is, there was no rocking. In Example 1, Example 2, and Comparative Example 1, 25 tile carpets were laid in a square shape in a vertical and horizontal alternating manner (so-called ichimatsu upholstery), and the number of butt sides was 40.
The results of observing and evaluating the joints on the sides are shown in Table 1.

[0023]

[Table 1]

[0024]

In the tile carpet of the present invention, since the pile in the vertical direction swings in the horizontal direction, the gap between the arbitrarily cut side and the pile closest to the side is small, so that the tile carpet can be arbitrarily abutted. Even if it is spread out, the joints can be constructed neatly and beautifully, so floor materials and wall materials for intelligent buildings, office buildings, luxury hotels, schools, libraries, waiting rooms such as hospitals, stations and airports, computer rooms, dining kitchens It can be preferably used as a ceiling material.
