More specifically, a plurality of pile lines individually have a predetermined direction, but as a whole the direction of the pile lines conflict with each other, the plurality of pile lines The present invention relates to a non-directional artificial turf structure having a random orientation and a method of manufacturing the same.

Artificial turf is a substitute for artificial grass made of synthetic fibers in the form of grass. Since it was first manufactured in the United States in 1956, it has been used mainly in sports fields such as baseball, soccer, and golf. It can be used in places such as indoor gardens or outdoor areas facing the north side of high-rise buildings with extremely limited sunshine hours.

In general, the artificial turf structure consists of a bubble layer, a pile layer formed by entering yarn into a bubble paper, and a support layer formed on the bottom surface of the bubble paper. Further comprising a filling layer formed by filling a filler such as silica sand between the upper portion and the pile. The pile layer was originally developed from nylon, but is gradually being replaced by polyolefin such as polyethylene or polypropylene to reduce friction. When the pile is formed by weaving yarns with the Raschel method or the mocket method, the bubble paper is mainly made of polyester (PET) foam paper, and then a tufting method that can form piles is developed. Many bubble papers are used. As the support layer, most of the acrylic resin and styrene-butadiene rubber (SBR) are used as the layer for strengthening the shape stability of the artificial turf structure, reducing noise, strengthening the tear strength, and strengthening the pull strength of the pile. Research has been actively conducted.

Looking specifically at the manufacturing method using the patterned needle bar sliding technology of the needle bar of the artificial turf structure manufacturing method according to the present invention, first the bubble paper 350 is supplied to the tufting device and at the same time Yarn is supplied to each of the plurality of needles provided in a line. As the needle bar descends and rises, the needle descends through the bubble and exits the bubble again, at which point the yarn is looped through the looper and the first file line consists of a number of loop files (indicated by "○" in FIG. 8). Is formed. The bubble is then moved in the longitudinal direction below and a space on the bubble is formed just below the needle to form a new pile line. Further, at the same time, the needle bar is moved at a predetermined interval in the left transverse direction, and each yarn supplied to the needle is moved at a predetermined angle in the left direction with respect to the loop pile position of the first file line formed by the same needle. The predetermined angle and the moving distance of the yarn are determined by the distance between the bubble paper moving in the longitudinal direction below and the distance between the needle bar and the left transverse direction. At this time, the loop file of the first file line looped to the looper is cut and converted into a file having a directionality. The directionality is the same as the direction in which the yarn is moved by the needle after the loop file is formed based on the loop file position. Accordingly, the plurality of piles constituting the first pile line have left deflection at a predetermined angle with respect to a normal line perpendicular to the transverse direction of the bubble paper. After imparting left deflection to the first pile line, the moved yarn is tufted onto the bubble paper and a second pile line consisting of a plurality of loop piles is formed.

At the same time, the needle bar may be moved at a certain interval in the right and left directions. In order to impart left deflection to file lines of a predetermined region and postal deflection to file lines of a predetermined region, the former method shown in FIG. 8 may be used, and one file line and another file adjacent thereto may be used. The latter method may be used to impart alternating left and post deflection along the longitudinal direction of the bubble. 8, the manufacturing method of the present invention will be described. After imparting left deflection to the second pile line, the moved yarn is tufted onto the bubble paper and a third pile line consisting of a plurality of loop piles is formed. Thereafter, the bubble paper is moved at a predetermined interval in the longitudinal direction below, and at the same time, the needle bar is moved at a predetermined interval in the right and horizontal direction. At this time, each yarn supplied to the needle is moved at a predetermined angle to the right direction with respect to the loop file position of the third file line formed by the same needle, and the loop file of the third file line is cut to form a zip direction. Will be converted to the file. That is, mail directivity is given to the third file line. After imparting left deflection to the third pile line, the moved yarn is tufted onto the bubble paper, and a fourth pile line consisting of a plurality of loop piles is formed. Thereafter, the bubble paper is moved at a predetermined interval in the longitudinal direction below, and at the same time, the needle bar is moved at a predetermined interval in the right and horizontal direction to impart postal directivity to the fourth file line. The artificial turf structure according to the present invention may be manufactured by repeating the formation of the first to fourth pile lines and the provision of deflection. As shown in FIG. 9, a zigzag-shaped pile piece is shown on the back surface of the artificial turf structure manufactured by the process of FIG. 8. The zigzag shape is a path in which yarns move along the longitudinal direction of the bubble paper by the same needle when the pile lines are formed by repeating tufting at regular intervals in the longitudinal direction of the bubble paper to form pile lines. In the artificial turf structure manufactured by the process of FIG. 8, as shown in FIG. 10, the deflection of the pile lines may be in conflict with each other, and the pile layer including the pile lines may have a random direction as a whole.
