Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pile fabric and a method for manufacturing the same. To be clear in history, the present invention is a special machine that is suitable for car mats, door trims used as automobile interior materials, carpets for general interiors, hot carpets for heat insulation, etc. This invention relates to a knitted fabric and a manufacturing method thereof.

Conventionally, in the above-mentioned product field, tufted carpets produced using tact machines have been the mainstream. However, since the tufted carpet requires an L-order base fabric, the amount of l is very large.
It has no elongation recovery properties as a fabric, and the processing performance due to the tufted roots' snaking makes the noodles stale, and it is not possible to obtain a structure with a tufted root length of 3 mm or less, which should not necessarily satisfy consumers. +! i: It could not be said that he had the ability.

The inventor of the present invention, as a result of intensive studies in order to eliminate the drawbacks of the conventional tufted carpet, has solved the drawbacks of the tufted carpet by creating a special pile structure using a warp knitting machine. The inventors have discovered that it is possible to obtain a tower structure, and have arrived at the present invention.

On the other hand, it is conventionally known to produce pile fabric using a warp machine. Conventional paddle piles produced by warp knitting machines include lining pile, *-shaped pile, force, and tow pile. Jk ground/
After knitting, yarn is made by raising the back side of the fabric to create a T4 shape, or by weakening the tensile strength of the fleece reed as much as possible and loosening the fleece yarn to create a shape. be. Therefore, in the mother of fleece fur, the ru of flat hair! The length was very short, making it difficult to perform the 114th knot of Tenshin training, and it was difficult to use thick fleece yarn. In the case of award-winning 4-ile, it cannot be knitted without using a Roots drawing device or 4-India needle, and therefore, Fi cannot be knitted on a normal warp machine that is not equipped with such special equipment. Power, To No 4
In the case of needles, it is also produced using a knife needle, or
Row needle bed warp - The pile yarn is knitted on both front needle beds of the machine, and the pile yarn is cut in the center of both needle beds. Therefore, it is not possible to organize force, force, and force with a normal war machine.

The present invention aims to provide a pile fabric having roots tiles of any length that can be knitted on a warp knitting machine without using any special equipment, and to provide a method for producing the same amount of roots tile. purpose.

According to the present invention, in a warp fabric having loops and armpits knitted on a warp machine having a single needle bed, the ground yarns are not knitted by some of the knitting needles, so that the ground knitted fabric has wales. It is assumed that a thin part that is noticeable in the direction is formed, and each pile yarn forms a loop/fill in the thin part of the ground knitted fabric.

Furthermore, according to the method of the present invention, when knitting a warp pongee fabric with 4 loops using a warp knitting machine with a single row needle bed, the ground knitted fabric is not knitted with all the knitting needles, but only with a part of the knitting needles. It is knitted only by knitting needles, while the pile yarn is connected to the ground by inserting or forming, and at the same time, it is fed to one needle that is not knitted with the ground to ground moonlight at an interval of one stitch or more to overlap it. Teru!・Characterized by forming a wall.

The inventors of the present invention have conducted intensive research on the red fabric of the armpit ile, and as a result, when knitting the embroidery fabric of the present invention, the inventors have found that when knitting the embroidery fabric of the present invention, a base iris is added to one stitch of knitting the armpit ile. Over the moonlight), when pinging, knit an open loop,
In the present invention, we have found that the thread for the main tile forms a roots tile at an angle of 55° to 1-25' with respect to the direction of the thread, and the sills are arranged in a ridge shape. Reached. That is, #1 is formed with a loop in the center at right angles to the pile warp, ground weave, and wale direction according to the present invention, and the loops and directions are uniform, and #1 is in contrast to the conventional wale direction. This is a new car mat, which is significantly different in appearance from the tuft machine-made roof pile, which produces parallel and non-uniform roof piles, and is a nine-pile material used in general carpets.

In the present invention, the pile yarn used is of course synthetic fibers such as IJ ester, nylon, and acrylic.

It may be a natural fiber, a regenerated fiber, or a semi-synthetic fiber, and there is no particular restriction.The ground yarn may also be a synthetic fiber, a regenerated fiber, a natural fiber, or a semi-synthetic fiber.
Its forms include yarn for yarns, filament yarns, bulky filament yarns, and spun yarns.

Chive yarn is used. However, the yarn used for the warp yarn of the present invention must be at least 5 times the thickness of the ground yarn, and more preferably at least 7 times the thickness of the ground yarn. . That is, by making the thickness of the luxurious moonlight five times (preferably seven times) or more the thickness of the ground thread, an appearance similar to that of a tufted carpet can be obtained.

The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a diagram showing the knitting diagram, the threading state, and the combination of chain links of a kiln red twill fabric according to an embodiment of the present invention. The ground yarns 11 and 12 constituting the ground knitted fabric each penetrate *Bt+i1m in a half set state,
On the other hand, Pi^/Gekkou 13, which forms Luso/9il, is B
, thread in half set. For explanation purposes, the needles arranged on the first row of needle beds are alternately marked with a and bl symbols and circles.

The ground yarn 11 is fed to the knitting needle a and is 2 of 1-272-1.
．． Repeat the ping to knit a 餉- (the chain link shown on the right side of Figure 1 shows the case of 3 Ten I), and use the ground yarn 1 and 2 for each stitch a. supplied with
Each chain of the ground yarn 11 is inserted by repeating 1-1/4-4 wrapping and is inlaid with the ground yarn 1.
They are connected to each other by the insertion section 2 and form a ground.

・In the recourse, the ground thread is supplied so as to be inserted into one stitch bK of knitting the ground thread. BsU idle swing. Then knitting needles a, b
performs a knock-off.

1 (2) course at Shanowa Ile Gekko 134-1 Oatskai
Wrap (2-3) is applied to one stitch that does not form a ground knitted fabric. Here, the pile yarn 13 is guided by a backswing from the right side of the knitting needle, and after being guided in the left direction for one stitch by a swivel motion, it is front-swung from the left side of the knitting needle. From this knitting movement, Nodile Gekko 13 is able to form a fist that forms a one-stitch bK open-eye rugu. In the (3rd) course, the needle Il Gekkou 13 feeds the fine needle bK (ltl) and performs insertion knitting. After that, the needles a and b are
In this case, in the second course, the ninth arm il Gekko 13 is held in the hook of the knitting needle, but in the third course In this case, since the p4 thread 13 is not supplied to each stitch,
When the thread 13 was knocked over and was held by the hook at the 9th point, 7. out of position, i.e. - needle force)
It also comes off, forming a loop pile 14.

In the (4)th course, the pile yarn 13 is fed to the knitting needles which do not form a ground with an ordinary lug (3-2).

Here, in contrast to the second course, we will use the thread 13 for the 4th course.
Backswing from the left side of the needle, then front swing from the right side of the needle. In the next (5) course, the (1)
Insert knitting is done in the same way as the course. At this time, the yarn 13 fed one stitch bK in the (4th) course comes off the one stitch bK and becomes a loop pile 14. Thereafter, the same organizing operation is repeated. As a result, every stitch #(2), #(4),
Loop piles 14 are formed in the (6), (8), and every other course, and in the (1), (3), and (5)
The (7th) course is connected to the ground-to-ground sinker loops by inserting the pile hanging thread 13d, and the glossy pile fabric of the present invention as shown schematically in Section 3E is obtained. Note that α in the figure is the angle of the arm loop with respect to the wale direction of the knitted fabric, and in the warp knitted fabric of the present invention, it is 55 to 125°.

In 1IIIil, an example is shown in which the loop pile 14 is formed every other stitch and every other course.
For example, knitting needles for knitting a ground knitted fabric may be used every 1 to several courses, and knitting needles for knitting a ground knitted fabric may be used every 2 to several courses. The loops 24 and 14 are connected every one to several stitches and every two stitches.
~ It can be formed every few courses, and as a method of applying the moonlight with circular needles for knitting the ground fabric, insert needles are used because the resulting lustrous ile can be made lighter. is preferable, but normal knitting may also be used.Furthermore, the male knitting may also be a chain consisting of two reeds, a normal tricot knitting, etc.
Good for making appropriate selections.

The above 5it1. The fabric of the present invention, which is knitted using the S principle, has the same function as the primary base fabric without using the primary base fabric, as shown in the model of the tufted car in Figure 4. Because it exhibits dimensional stability, it becomes an extremely lightweight material with excellent dimensional stability.

In addition, since it is basically composed of a warp-loop structure, it has excellent elongation recovery properties (2) and (3), making it suitable for automobile interior materials that require three-dimensionality, such as car mats and doors). When used, it exhibits a lexical function and greatly improves molding performance. In addition, since the /4 tile is held within the ground-ground loop, there is no possibility of removing the pile due to external force.Therefore, removing the glossy tile during the dyeing process is completely eliminated, and productivity in the dyeing process is improved. Improving in leaps and bounds. In addition, it is an IT capability to freely adapt the supply system of the pile yarn to the maximum length or shortest length of the supply system for supplying pile length, or changes in the parent pile structure, etc. It is possible to arbitrarily select the height or length as needed, up to 10-length. Furthermore, from the fist where the pile loops are organized as the main loops, the pile loops are uniformly formed at right angles to #1 and the direction of the expanding ground wale, and the glossy piles are arranged in a ridge shape, making a strange sound. It becomes a parable with a new nodile form that does not exist in the world.

According to the method of the present invention, it is possible to create a warp knitted fabric with armholes on a normal one-row needle bed warp knitting machine without using a special warp knitting machine. Since no separate operation is required to form the knitted fabric, it can be knitted at the same speed as knitting regular warp knitted fabrics, increasing production efficiency.
