Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for knitting a plain jacquard knitted fabric into a tubular shape by using a flat knitting machine.

[0002]

2. Description of the Related Art Conventionally, a knitting method called a plain jacquard or a floating jacquard is known. In the knitting method, for example, in the case of a black and white bi-colored Jacquard jacquard, the black yarn is knitted in the region where the black yarn appears on the knitted fabric surface, while the white yarn is missed and the white yarn appears next on the knitted fabric surface. The knitting yarn crosses the back surface of the knitted fabric without forming a loop,
It will be in a state called floating. On the contrary, in the area where the white yarn appears on the surface of the knitted fabric, the black yarn is in a floating state where the knitting yarn crosses the back surface of the knitted fabric without forming a loop.

As a knitting method for a knitted fabric, after the knitting yarn is supplied to the front needle bed, the knitting yarn is supplied to the rear needle bed, and the knitting yarn is supplied in a circular shape in the front needle bed. A knitting method called tubular knitting is also known, in which a knitted fabric to be knitted and a knitted fabric to be knitted on a rear needle bed are knitted in a state of being connected at both end portions of a knitting region. The knitted fabric knitted in this way can be used, for example, when the front body part of the sweater is knitted with the front needle bed and the back body part is knitted with the rear needle bed. Knit the body parts separately, and after knitting,
Since the post-treatment for connecting both body parts by sewing is not necessary, the production cost of the product can be reduced.

The present invention relates to a method of knitting a plain cloth jacquard knitted fabric into a tubular shape. The conventional methods of knitting a plain cloth jacquard knitted fabric into a tubular shape have a number corresponding to the number of colors used for knitting. The knitting yarn is supplied to the needles of the front and rear needle beds in a circular or counterclockwise direction, and the front needle beds are also
It was common to knit the needle bed at the rear using the same yarn feeder.

[0005]

A conventional knitting method is, for example, a plain portion 101 and a shaded portion 1 as shown in FIG.
In the case of knitting a striped pattern Jacquard having a striped pattern 02 appearing alternately on the surface of the knitted fabric (actually, the yarn feeder is reversed at the location of the line V-V to knit a tubular knit, but for convenience of explanation 6 shows a state in which the line is developed centering on the line VV, the left side of the line VV is knitted with the front needle bed, and the right side is knitted with the rear needle bed.), FIG. Using the yarn feeder M appearing on the knitted fabric surface in the portion 101 and the yarn feeder N appearing on the knitted fabric surface in the plain portion 102, the yarn feeding port M is used by the leading cam of the double cam and the yarn feeding port N is used by the trailing cam. Knit on the needle bed behind to the right. Next, in FIG. 7-2, the carriage is reversed and knitting is performed with the same yarn feeders M and N as in FIG. 7-1 to the left in the front needle bed, and the knitting yarn is supplied in a circular shape in the clockwise direction. In the knitted fabric knitted in this way, as shown in FIG. 8, the knitting yarn supplied by the yarn feeder N that crosses the back surface of the knitted fabric without forming a loop at the hatched portion,
First, the knitting yarn is supplied to the point T in the right direction, and after the carriage is inverted, the knitting yarn is supplied from the point S when the knitting yarn is supplied in the left direction. Therefore, the knitting yarn supplied from the yarn feeder N is short-circuited from the point T to the point S on the needle bed which directly opposes the point T without passing through the point V which is the side end of the knitting region. As a result, the inner diameter is narrowed with respect to the tubular diameter of the tubular knitted fabric, and there is a problem that the short-circuited bridging yarn is caught when the knitted fabric is worn, and is cut or unraveled.

The present invention provides a knitting method which does not cause problems such as narrowing the inner diameter of the tubular knitted fabric and cutting short-circuited bridging yarns, which the conventional knitting methods described above have. The challenge is to provide.

[0007]

In order to solve the above problems, the knitting method of the present invention is a method of knitting a tubular knitted fabric of a plain jacquard with a flat knitting machine having at least a pair of front and rear needle beds. Of the yarn feeders that can move on a plurality of yarn guide rails that are installed in the longitudinal direction of the needle bed, the yarn feeder groups on the yarn guide rails that are located behind the yarn feeder groups that are used for knitting on the rear needle bed. The yarn feeder groups are divided so that they can be used for knitting on the front needle bed, and one of the divided yarn feeder groups knits one course of the Tenjiku Jacquard knitted fabric, which is one side of the tubular knitted fabric, and each yarn feeding port is knitted. Is moved to the outside of the knitting area of the knitted fabric, and by the remaining yarn feeder groups, one course of the knitted fabric of Jacquard on the other side of the tubular knitted fabric is knitted, and each yarn feeder is moved to the outside of the knitting region of the knitted fabric. The knitting yarns of each yarn feeder group separated outside the knitting area After inserting, knit the Tenjiku Jacquard knitted fabric by using the yarn feeder group on the side where the knitting yarn is below the intersection first and move each yarn feeder to the outside of the knitted fabric knitting area. By knitting the plain jacquard knitted fabric using the remaining yarn feeder group and moving the yarn feeder outside the knitted fabric knitting area, by repeating the above-mentioned knitting, knitting of the divided yarn feeder group at both end portions of the knitted fabric is performed. It is characterized in that the yarns are entangled with each other, and that each piece of jacquard knitted fabric is knitted on both front and back needle beds.

[0008]

In the knitting method of the present invention, outside the knitting area of the knitted fabric, the knitting yarn used in the front needle bed and the knitting yarn used in the rear needle bed for knitting intersect in the next course. Since knitting is performed, the knitted fabrics that are knitted on both the front and rear needle beds are connected and formed into a tubular shape, and the knitted fabric is in a floating state across the back surface without forming loops at both end portions of the knitted fabric. The yarn is entangled with the knitting yarns used in the needle beds facing each other at both ends of the knitted fabric, and is knitted in the next course while being held at the knitted fabric side end.

As described above, in the method disclosed in this embodiment, the knitting yarns supplied by the divided yarn feeders are in a state of being interlaced at both end portions of the knitted fabric. Therefore, the knitting is formed only up to the points X and Y inside the side end of the knitted fabric, and the knitting is supplied by the yarn feeders A and C which are in a floating state without forming a loop in the shaded portion 2. In the state where the yarn is held at the side end of the knitted fabric due to the interlacing of the knitting yarns at the V-V line, the stitches are formed again at the points X and Y in the next course. As a result, the knitted fabrics knitted on both the front and rear needle beds are connected at both ends to form a tubular knitted fabric, and knitted by the yarn feeders A and C which are in a floating state at both end portions. The yarn is woven into the next course without short circuit.

In the present embodiment, the case of the two-colored plain jacquard has been described as an example, but it is also possible to knit three or more colors of the plain jacquard, and the present invention is described in the embodiment. It is not limited to the range.

[0019]

As described above, in the method for knitting a tubular knitted fabric for a plain jacquard of the present invention, a yarn feeder group used for knitting on the front needle bed and a yarn feeder used for knitting on the rear needle bed. The knitting yarns divided into groups are entangled at both end portions of the knitted fabric, and the knitted fabrics knitted on both the front and rear needle beds are connected, and loops are not formed at both end portions of the knitted fabric. The knitting yarn that floats across the back side of the knitted fabric is entangled with the knitting yarn that forms the knitting fabric that is knitted on the needle beds facing each other at the side end of the knitted fabric, and is knitted into the next course while being held. Therefore, the knitting yarn does not short-circuit and cross between the knitted fabrics knitted on both the front and rear needle beds. Therefore, the problems that the conventional knitting methods have, such as narrowing the inner diameter with respect to the cylinder diameter by the transition yarn and causing the short-circuited knitting yarn to be caught and broken during wearing, do not occur.
