Description

Description: TECHNICAL FIELD The present invention relates to a tile carpet made of tufted pile fabric.

[Conventional technology]

Tile carpets are made by cutting a long tufted carpet lined with heavy backing in a rectangular shape by matching the length and width directions of the length and width directions.

Of course, a method of cutting diagonally as disclosed in JP-B-63-39244 is also conceivable, but doing so will result in a triangular cutting loss at the left and right ends of the long tufted carpet. In order to cut diagonally, a special cutting device is required, and it is considered that practical application is difficult in terms of production efficiency.

A back stitch 15 of a tufted carpet conventionally used for a tile carpet is linearly continuous in a stitch direction S, and a zigzag tufted carpet tufted zigzag in the stitch direction S is not used for a tile carpet.

That is, in order to tuft the back stitch 15 so as to intersect the stitch 16 in a zigzag manner, the needle is moved to the looper of the next stitch row in each stitch cycle, or the entire primary base fabric is left and right width of the tufted machine. The zigzag tufted carpet is not required to make a tile carpet, although it may be swung.

The reason is that zigzag tufting is performed so that even if there are spots such as color spots, counts, twist spots, etc. on a part of pile threads that are arranged and tufted, straight continuous warp and flaw defects cannot be formed on the pile surface. Tile is a type of demonstrating means that is adopted as a patterning means for drawing a checkered or marbling pattern on a pile surface by alternately arranging pile yarns having different colors and tufting in a zigzag manner. Carpets are cut into 30 to 50 cm squares and are laid in a checkered pattern by changing the length and width, so even if warp or flaw defects occur during temporary tufting, In the installed state, the warp appears only in a limited short range of 30 to 50 cm, does not appear continuously from the end of the construction surface, and the warp appears in such a short range・ Scratch defect is Taylor It is identified with the seam of the pet and does not catch the eye, so it does not impair the appearance of the construction surface.On the other hand, the geometric pattern such as the stripes and checkered patterns formed on the pile surface is curved and deformed by the rabbit corner backing process etc. The piles are not aligned straight along the direction S or the gauge direction G, and it is practically impossible to cut the tile carpet vertically and horizontally to the stitch row (S) or the gauge direction S. This is because tile carpets cannot be cut out according to the geometrical design of the surface, and even if it is cut out, only defective products whose design does not fit at the seam of the construction surface can be produced.

[Problems to be solved by the invention]

As described above, the conventional tile carpet is made by cutting a tufted carpet in which the back stitch 15 is straight and continuous in the stitch direction S by aligning the cutouts (17 and 18) in the stitch direction S and the gauge direction G. Since the back stitch 15 is not interposed between the stitch row 16 and the stitch row 16 'in the gate direction G, (1) When cutting is performed at the center between the stitch rows 16 and 16', When the pile 12 and the back stitch 15 do not appear directly, but are cut just above or just before the stitch row 16, the pile 12 and the back stitch 15 appear to protrude into the cutout 17 (FIGS. 7 and 8). As shown in the figure), the shape of the cutout 17 along the stitch row 16 changes depending on the cutting position.
Therefore, the shape of the tile carpet becomes uneven, and (2) the cutout 18 along the gauge direction G is always the cutout of the back stitch 15 of each stitch row 16, 16 ', 16 ".
19 ・ 19 ′ ・ 19 ″... Appear as dots (FIG. 9), but the back stitches 15 do not appear as such at the cutout 17 along the stitch row 16 as described above, and The cutout 17 along the gauge direction G is different from the cutout 17 along the gauge direction G. (3) In the stitch direction S, the space between the piles is connected to the back stitch 15 (FIG. 7, FIG. 8), the piles (stitch rows 16 and 16 ') are not connected by the back stitch 15 in the gauge direction G (FIG. 9), and the back stitch 15 is long and continuous in the stitch direction S like that. However, since they are not continuous in the gauge direction G, the stretching strength and the bending strength are different in the stitch direction S and the gauge direction G, and are weak and flexible in the gauge direction G and easily expand and contract.

As described above, the appearance and physical properties of the conventional tile carpet are different in the vertical and horizontal directions. (1) The pile does not become sparse at the seam where the cutouts (18) along the gauge direction G meet, but the stitch direction S The piles are sparse at the seams where the cuts (17) are joined along the (2), and (2) tile carpets having different pile warpage in the vertical and horizontal directions, and the cuts warped in the gauge direction G (18) ), And when the cutouts (17) along the stitching direction S are laid against each other, the warp habit appears straight and continuously so as to form a ridge on the construction surface. (3) Cutting along the stitching direction S In mouth 17, pile
Since the entire back stitch 15 that joins 12 to the backing layer is exposed, all the piles 12 appearing at the cutout 17 are easily broken, especially in the case of a loop pile, from one broken pile to all the cuts 17 There are inconveniences such as the pile being pulled out in a pot-vine manner.

Defects in appearance that occur on the construction surface due to such irregularities in vertical and horizontal appearance and physical properties, that is, sparse seams of the pile, warpage of the pile surface, broken marks of the pile, etc. are straight against the seams of the tile carpet. In order to camouflage the inconvenience of the construction surface that appears next, the actual situation is that tile carpets are constructed in a checkered pattern by changing the vertical and horizontal directions alternately one by one.

[Object of the invention]

Therefore, an object of the present invention is to obtain a tile carpet in which the pile 12 is hardly broken at the cutouts 17 along the stitch rows, having the same physical properties and appearance in the vertical and horizontal directions.

[Configuration of the invention]

That is, as shown in the figure, the tile carpet 14 according to the present invention has a structure in which a heavy backing layer 13 is laminated on the back surface of a tufted pile fabric in which the pile 12 is tufted on the primary base fabric 11, and the pile has a gauge direction G and a stitch direction S. The back stitches 15 are crosswise zigzag in the stitch direction S continuously and diagonally left and right alternately in a range M of 2.5 pile gauges (2.5X) or more. It is assumed that.

In order to tuft the back stitches 15 so as to intersect zigzag in the stitch direction S, the needle or the primary base cloth 11 may be moved in the gauge direction G in each stitch cycle as described above, and the movement range M When the needle is moved, the distance between the stitch rows is an integral multiple of the needle gauge X, but when the primary base cloth 11 is moved, the needle gauge X is halved (0.5X) or half of the needle gauge X regardless of the needle gauge X. Can be arbitrarily set as 1.5 times (1.5X).

When the tufted carpet in which the back stitch 15 is zigzag in this way is cut in the stitch direction S, the turning point 20 of the left and right zigzag back stitch 15 is such that the left and right zigzag range M is equivalent to one pile gauge (1X). In this case, every other stitch, every two stitches (2X), every two stitches, and as shown, every five stitches (5X), every five stitches.
Each stitch corresponding to the number of pile gauges that zigzag right and left will appear in the cutout 17 at a rate of once, but the pile 12 at the turning point 20 is a slight back stitch part 21 left behind at the root. It is merely bonded to the backing layer 13 (FIG. 5), and thus easily breaks down.

In particular, the zigzag right and left between one pile gauge (1X) and the back stitch turning point 20 is cut every other stitch.
17, a conventional tile carpet in which the back stitch continues in a straight line in the stitch direction (FIG. 7, FIG. 8)
As in the case of FIG. 2), all the piles 12 in the cutting opening 17 are easily dropped.

Therefore, in order to prevent the pile 12 from falling off at the cutout 17, at least a range corresponding to a 2.5 pile gauge (2.5
X) zigzag the back stitch from side to side, and at least half the piles 12 of the cutouts 17 along the stitch rows 16
It is essential that the back stitch 15 is continuous from the cutout 17 to the inside and adheres and holds the backing layer 13, and preferably the back stitch is zigzag left and right in a range of 5 pile gauge or more (5X or more), More preferably 5.5X or 6.
The back stitch is zigzag left and right in a range M not to be an integral multiple of the pile gauge (X), such as 5X.

The backing of the tufted pile fabric is performed by a conventional method, and a non-stretchable yarn such as glass fiber or a coarse secondary base fabric of a net can be inserted into the inside of the backing layer. Also, an extremely thin nonwoven fabric, paper, or the like can be attached to the back surface of the backing layer 13.

〔The invention's effect〕

As described above, the back stitches 15 of the tile carpet 14 according to the present invention intersect in the stitch direction S, so that the cut holes 17 along the stitch direction S have the same shape as the back stitches 15 along the gauge direction G. The cut 19 of the cut back stitch 15 continues inside the cut 17 so that the pile 12 does not unravel from the cut 17 and the vertical and horizontal cuts 17 and 18 have the same appearance .

The back stitch 15 is continuous in the diagonal direction crossing both the stitch direction S and the gage direction G, and is not continuous straight in those directions. The back stitch is continuous diagonally between the pile gauge and the stitch. The difference between vertical and horizontal expansion and bending strength and bending strength is eliminated, and therefore, it is also necessary to use extra expensive backing materials and the like that were conventionally required to reinforce the strength of the back stitch in the discontinuous gauge direction G. Instead, it is also possible to reduce the cost by laminating the backing layer thinly, and to make the pile surface flat with the vertical and horizontal directions instead of the checkerboard shape.

As described above, according to the present invention, the vertical and horizontal appearances and physical properties are equal, the cutouts 17 and 18 can be straightened and the pile surface can be formed smoothly, and the abrasion resistance that does not easily break at the cutouts (17 and 18) This is advantageous because a tile carpet excellent in quality can be obtained at low cost.
