[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for knitting a pile knitted fabric using a knitting machine in which a plurality of yarn feeders are simultaneously run in a predetermined order above intersections of knitting needles from both front and rear needle beds.

[0002]

2. Description of the Related Art As one of the methods for knitting a pile knitted fabric with a knitting machine, there is a method of using two yarn feeders ("Introduction to Flat Knitting Technology" 281-issued by Seny Journal Co., Ltd.).
282). In this knitting method, a knitting yarn is supplied to a crossing portion of knitting needles on both front and rear sides, that is, a crossing portion of knitting needles from both front and rear needle beds from above and a first yarn feeder and another knitting yarn are provided on the side of the crossing portion. And a second yarn feeder supplied from one side (front or rear) are run at the same time, the knitting yarn from the first yarn feeder is drawn in by a knitting needle on the rear side, and both knitting yarns from the first and second yarn feeders are drawn. A yarn is drawn by the front side knitting needle to form a stitch by the front side knitting needle, and the knitting yarn drawn by the rear side knitting needle is removed in a loop state without forming a stitch to form a pile.

As another method of knitting a pile knitted fabric with a knitting machine, there is a method of using a yarn feeder having first and second yarn paths (the above-mentioned "Introduction to Flat Knitting Technology" 283 to 28).
6). In this other knitting method, the knitting yarn from the first yarn path is pulled in by the back side knitting needle, and both knitting yarns from the first and second yarn paths are pulled in by the front side knitting needle and knitted by the front side knitting needle. Is formed, and the knitting yarn drawn by the knitting needle on the rear side is removed in a loop state without forming the knitting yarn to form a pile.

However, in all the conventional knitting methods,
Since the knitting yarn used as the pile yarn is limited to the knitting yarn from the first yarn feeder or the first yarn path, the type of pile yarn used cannot be changed during knitting. Also,
The number of pile threads cannot be changed. Therefore, in the conventional knitting method, various pile knitted fabrics cannot be knitted by changing the type of pile yarn or changing the number of pile yarns.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to knit various pile knitted fabrics.

[0006]

According to a knitting method of the present invention, a plurality of yarn feeders in which one or more knitting yarns are respectively inserted are arranged in an order based on a predetermined knitting plan above an intersection of knitting needles from both front and rear needle beds. While running at the same time, and pulling in at least one knitting yarn including the knitting yarn from the leading yarn feeder and excluding the knitting yarn from the last yarn feeder with one of the front and rear needle beds, A loop is formed by simultaneously drawing all the knitting yarns from the plurality of yarn feeders with the knitting needles on either the front side or the back side to form stitches, and looping the knitting yarns drawn by the knitting needles on the one side without forming the stitches. It includes removing from the knitting needle as it is, and changing the traveling order of the plurality of yarn feeders during knitting.

[0007] Either side of the front and rear needle beds (for example,
The knitting needle of the rear needle bed includes one or more knitting yarns including the knitting yarn from the earliest yarn feeder and excluding the knitting yarn from the last yarn feeder. On the other hand, the knitting needle on the other side of the front and rear needle beds (for example, the front needle bed) draws all the knitting yarns supplied to the intersection to form a stitch. The knitting yarn drawn by the knitting needle on one side is then removed from the knitting needle as a loop without forming a stitch. As a result, a pile is formed. When the traveling order of the yarn feeders is changed during knitting, the knitting yarn drawn by the knitting needle on one side is changed, so that the knitting yarn used as the pile yarn is switched.

As described above, according to the present invention, the knitting yarn to be used as the pile yarn can be changed only by changing the running order of the plurality of yarn feeders running above the intersection of the front and rear knitting needles. .

In another knitting method of the present invention, three or more yarn feeders, each of which has one or more knitting yarns inserted therein, are provided above the intersection of knitting needles from both front and rear needle beds in an order based on a predetermined knitting plan. Running at the same time and drawing in one or more knitting yarns including the knitting yarn from the leading yarn feeder and excluding the knitting yarn from the last yarn feeder with one of the front and rear needle beds, and Forming stitches by simultaneously pulling in all the knitting yarns from a plurality of yarn feeders with the knitting needles on the other side of the front and rear needle beds, and without forming the stitches on the knitting yarns drawn by the one side knitting needles. The process includes removing the knitting needle from the knitting needle while keeping the loop, and changing the number of knitting yarns drawn by the knitting needle on the one side during knitting. When changing the number of pull-in knitting yarns with one side knitting needle from, for example, 1 to 2, 2 to 1, always run three yarn feeders at the same time and set only the number of pull-in yarns to 1. It may be changed from two to one from two, or two yarn feeders are run at the same time when the number of draws is one, and three yarn feeders are run at the same time when the number of draws is two. You may allow it.

According to another knitting method of the present invention, the number of pile yarns to be used can be changed by changing the number of knitting yarns drawn by the knitting needle on one side.

The running order of the yarn feeder and the number of knitting yarns to be drawn in may be changed for each knitting pattern portion adjacent in the course direction, or for each knitting pattern portion adjacent in the wale direction. May be performed for each knitting pattern portion adjacent in the course direction and for each knitting pattern portion adjacent in the wale direction.
By changing the running order of the yarn feeders and the number of drawn knitting yarns in this way, various pile knitted fabrics having different shades or textures in adjacent knitting pattern portions can be obtained. Furthermore, if you change the running order of the yarn feeder and the number of pull-in yarns,
A wider variety of pile knitted fabrics can be knitted.
