6i・1・There is a disadvantage that the yarn has a direction 11: and the pile falls down.

Therefore, conventional artificial turf fabrics have generally been woven fabrics made from synthetic fibers as pile yarns, or fabrics with pile yarns attached to woven fabrics using a tufting machine, and knitted fabrics have not been used.

However, as mentioned in O1S, knitted fabrics are superior as fabrics for artificial turf, and the inventor of the present invention points out that the pile has directionality, and if this drawback is solved, it can be used as fabric for artificial turf instead of woven fabrics. As a result of various researches, we found that the directionality of haha no kuiru could be solved by knitting a pile structure using two types of pile yarns, which are a mixture of straight yarns made of normal fibers and curly yarns that have undergone permanent set processing. I found out. This invention was made based on this knowledge.

In other words, the gist of this invention is as follows: (1) supplying warp and weft yarns to the front and rear knitting needle rows of an O-double warp knitting machine, respectively, and knitting two front and rear fabrics at the same time; Straight fiber yarn and curled yarn with permanent set processing are used as two types of pile yarn.

When the cut pile structure is formed as described above, the tension applied during knitting is removed, so that the pile yarn (9) returns to its original curled state. Therefore, the pile becomes a state in which the pile of curled yarn is entangled at the root of the cut pile of sullate yarn, and even if the straight yarn tries to tilt, the curled yarn supports it and prevents it from falling over, resulting in the formation of a non-directional pile. be done.

As mentioned above, this invention forms a cut pile with two types of pile yarns, slate yarn and curled yarn, and the two are intertwined to form a non-directional pile, which makes it difficult to slip.
It can also be provided as a fabric for artificial turf with excellent drainage properties.
