BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitted fabric, and more particularly, to a knitted fabric using a pile yarn in which a release cross-section yarn made of polyester mono filament yarn is bonded.

In general, the double-latssel knitting machine is to weave the knitted fabric into a synthetic fabric, and is provided with six guide bars for supplying yarns by swinging and wrapping operations, and a trick plate that is fixedly arranged in each of the longitudinal directions of the guide bars. And a plurality of needles that elevate on each side of the trick plate, and a sinker that moves forward and backward in the horizontal direction toward each trick plate with the needles interposed therebetween. Two guide bars, each positioned at the front and the rear of the guide bars, form the bubble tissue at the front and the rear of the knitted fabric paper, and the two guide bars at the center are formed between the front and rear surfaces of the knitted fabric. To organize.

In other words, the knitted paper by the double ratchet knitting machine is knitted by a slope supplied from the guide bar in front of the double rassel knitting machine, a rear surface knitted by another slope supplied from the rear guide bar, and a guide located in the middle. The pile yarn supplied from the bar consists of a three-dimensional pile section knitted with two warp yarns.

Knitted paper made of such a tissue is generally used in the three-dimensional knitted fabric using a synthetic fiber in the front and rear in the range of 75 to 250 denier and a spun yarn as a pile yarn. Here, Denia represents the diameter of one strand of yarn when 1 g of raw material is spun into 9000 m yarn.

In order to weave this knitted fabric, first, the fibers to be transferred from the raw material process are stretched to some extent and then proceeded to an opening process to smooth the next process. In this process, different quality grades of short fibers are mixed or different fibers are mixed with each other, depending on the purpose of manufacture. At this time, the mixing degree of the polyester staple fiber (polyester staple fiber) is about 20 to 70%.

The fibers transferred in the process are subjected to a short fiber removal process. This short fiber removing process removes short fibers, which cause weak yarns or uneven yarns, to be mixed with cotton wool, woolen, carding, or regular cotton wool.

The irradiated manufacturing process makes a bundle of cotton by a carding machine, joins and stretches a few strands of thread in the drawing process, makes the thickness even, arranges the fibers, and thins the thickness.

Finally, the fiber speed is increased to the desired thickness, twisted to make a thread, and then the thread is wound to an appropriate size. This is called the spinning process. After this spinning step, there may be a process of joining two or more strands or smoothing the remaining hairs of the yarn by a gas fire, or performing a wax treatment depending on the intended use. This is called an orthodontic process.

The combined discharge yarns are dyed in various colors in order to make a vehicle seat with the spun yarn combined in this orthodontic process.

The vehicle seat is manufactured using the yarns as described above. Therefore, it is necessary to cut the fiber to a certain length in order to make staple fibers into long fibers. At this time, the length of the staple fiber is about 10 ~ 105mm. In addition, a stretch crimp is given to make straight staple fibers curl like fleece.

When the yarn is used, fine dust is generated in the workshop when weaving the knitted fabric, which causes detriment to the health of the worker, and may cause defects due to cutting during weaving, resulting in lower productivity. If a vehicle sheet is manufactured and used using knitted paper, the fibers of dust and staple fibers are continuously removed, thereby deteriorating the cleanliness of the vehicle.

The present invention has been made in view of the above points, and its object is to reduce the working process, to prevent the generation of fine dust during weaving, to improve productivity, and to use the knitted paper to prevent dust and staple fibers from falling out, and using the knitted paper Provided is a vehicle seat.

Knit paper according to the present invention,

A front surface knitted by a first slope supplied from a front side guide bar in a double ratchet knitting machine;

A rear surface knitted by a second slope supplied from the rear side guide bar against the front surface, and

Pile piled together with the first and second warp yarns of a pile cross-section yarn composed of polyester monofilament yarns supplied from guide bars located in the middle of the front and rear guide bars, to form a three-dimensional structure. Contains wealth.

The release cross-section yarn forming the pile portion is formed by alternately providing a straight portion and an enlarged portion formed with a width larger than the width of the straight portion on the cross section.

The release cross-sectional yarn forming the pile portion has first and second curved portions having the same width on the cross section, and repeatedly forms the curved directions of the first and second curved portions in the same direction or alternately in the opposite direction.

The release cross-section which forms the said pile part is formed with the center part in cross section and the straight part formed in all directions from this center part.

The knitted fabric is formed by slitting cut pile part.

In addition, the vehicle seat of the present invention is formed of a knitted paper using a pile yarn that combines the above-described release cross-sectional yarn.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
