Description

[Technical field]

[0001] The present invention relates to a method for knitting a pile fabric using a flat knitting machine. [Background technology]

[0002] A flat knitting machine having a pair of front and rear needle beds is used to knit a course on one of the front and rear needle beds, and then the course knitting is repeated on the other needle bed, so that a tubular knitted fabric can be obtained by circulating the knitting yarn around the front and rear needle beds. Such tubular knitted fabrics are used for, for example, gloves and socks.

[0003] In order to apply a pile structure to a knitted fabric, a flat knitting machine equipped with a pile knitting sinker is used. As shown in FIG. 2, the pile knitting sinker 10 has a ground yarn hook 13 at the tip side of the working arm 11 and a pile thread During knitting, a ground yarn feeder and a pile yarn feeder (not shown) are used, and by moving the ground yarn feeder ahead of the pile yarn feeder, the ground yarn (finishing yarn) can be fed to the hook of the knitting needle in a state where it is lower than the pile yarn. thread If the hook 14 can be inserted, a pile fabric can be knitted.

[0004] However, in the case of a flat knitting machine in which the carriage moves back and forth while reversing between the left and right sides of the knitted fabric, the height difference between the pile yarn and the ground yarn cannot be made large enough at the beginning of knitting after the carriage reverses, so the pile thread There was a problem that the hook 14 could not be securely inserted into the gap.

[0005] In Patent Document 1, a special knitting needle with a knitting yarn retaining hook on the inner edge facing the hook of the latch portion is attached to a flat knitting machine, and the ground yarn is retained by the knitting yarn retaining hook of the latch and the knitting needle is pulled down, thereby increasing the height difference between the ground yarn and the pile yarn, so that the pile yarn hook can be reliably inserted into the gap. Therefore, in order to knit a pile fabric, it was necessary to attach not only a pile knitting sinker but also a knitting needle with the above-mentioned special configuration to the flat knitting machine.

[0006] [Patent Document 1] Special Publication No. 60-59333 Summary of the Invention [Problem to be solved by the invention]

[0007] An object of the present invention is to provide a method for knitting a pile fabric without using knitting needles with a special structure as described in Patent Document 1. [Means for solving the problem]

[0008] In the present invention, a method for knitting a pile fabric using a flat knitting machine is provided with a pair of front and rear needle beds on which a number of knitting needles are attached with their needle gaps sandwiched therebetween, and a pile knitting sinker having a ground yarn hook and a pile yarn hook formed above the ground yarn hook on the needle beds, and the ground yarn is fed from a leading yarn feeder and the pile yarn is fed from a trailing yarn feeder, while the ground yarn is hooked by the ground yarn hook of the pile knitting sinker and the pile yarn is hooked by the pile yarn hook, and a course knitting of one of the front and rear knitted fabrics constituting a tubular knitted fabric is then repeated on one needle bed, followed by course knitting of the other of the front and rear knitted fabrics on the other needle bed, thereby knitting a tubular pile fabric in courses, wherein in the course knitting of one of the front and rear knitted fabrics, the knitting needle located at the side end on the knitting start side is used In step A, a course of one of the knitted fabrics is knitted with the knitting needles except for the one positioned at the side end of the knitting start side, and at the knitting end side, after the carriage has turned around, yarn is fed to the knitting needles positioned at the side end of the knitting start side of the other knitted fabric to form stitches; in the subsequent course knitting of the other knitted fabric, a course of the other knitted fabric is knitted with the knitting needles except for the one positioned at the side end of the knitting start side, and at the knitting end side, after the carriage has turned around, yarn is fed to the knitting needles positioned at the side end of the knitting start side of the one knitted fabric to form stitches; by repeating steps A and B, the ground yarn is held in the ground yarn hook claws of the pile knitting sinker, and stitches are formed with the pile yarn held in the pile yarn hook claws. Effect of the Invention

[0009] In the present invention, the ground yarn is first pulled in by the knitting needle located at the side end on the knitting start side, and then course knitting is performed with the knitting needles other than the above-mentioned knitting needle, so that a large height difference can be formed between the ground yarn and the pile yarn. Therefore, the pile yarn hook can be reliably inserted into the gap between the ground yarn and the pile yarn, so that the pile fabric can be knitted without using knitting needles with a special structure as in the past. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 illustrates the knitting steps according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a diagram showing a pile knitting sinker. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] The flat knitting machine used in this embodiment is the same as that in Patent Document 1, except that general knitting needles are attached instead of the knitting needles with a special structure for pile knitting. Therefore, when knitting a pile fabric, the ground yarn, the pile yarn and the ground yarn feeder, the pile thread The operation of the yarn feeder, the yarn feeding conditions, the opening and closing operation of the sinker when forming stitches, the movement of the knitting needles, etc. are the same unless otherwise specified, so a description thereof will be omitted.

[0013] Figure 1 is a diagram showing the knitting steps of a pile knit fabric. S shown in the left column of the figure indicates each knitting step. F indicates the front needle bed, B indicates the back needle bed, lower case letters indicate the position of the knitting needles on the front needle bed, and upper case letters indicate the position of the knitting needles on the back needle bed. Dots indicate knitting needles, circles indicate stitches, and left and right arrows indicate the direction of carriage movement, i.e., the knitting direction.

[0014] In the figure, the rear fabric 1b of the tubular fabric 1 is knitted using the knitting needles on the rear needle bed when the carriage moves to the right, and the front fabric 1f of the tubular fabric 1 is knitted using the knitting needles on the front needle bed when the carriage moves to the left, so that the knitting yarn is supplied circularly in a clockwise direction to knit the tubular fabric 1.

[0015] S0 indicates the state of engagement of the stitches on each needle bed of the tubular fabric 1, with the stitches of the front fabric 1f being engaged on the knitting needles aj of the front needle bed, and the stitches of the back fabric 1b being engaged on the knitting needles AJ of the back needle bed. Although the yarn feeder is not shown, knitting up to S1 is performed using a ground yarn, and from S2 onwards, the pile fabric is knitted using two knitting yarns, the ground yarn and the pile yarn.

[0016] S1 indicates knitting immediately before the start of course knitting of the pile fabric. When the carriage moves to the left, course knitting is performed with the knitting needles j-a on the front needle bed, and yarn is also fed to the knitting needle A at the side end of the rear knitted fabric 1b that faces the knitting end side of the front knitted fabric 1f to form stitches. This knitting needle A becomes the knitting needle located at the side end of the knitting start side of the rear knitted fabric 1b when the carriage reverses and moves to the right. The stitch formation with the knitting needle A here is a preparation process for knitting the pile fabric starting from the next course.

[0017] In the next step S2, the carriage is moved to the right and the rear fabric 1b is knitted with the knitting needles BJ except for the knitting needle A. Here, the knitting needle A that formed stitches in step S1 is not operated in step S2 and is kept in a retracted state while the rear fabric 1b is knitted. Therefore, at the knitting start side of the rear fabric 1b, the knitting needle B is the actual knitting start needle. When the knitting needle B forms stitches, the ground yarn extends from the hook of the knitting needle A, which is already retracted, to the ground yarn feeder, so that the pile yarn is not knitted. thread As a result, a large height difference is formed between the pile yarn extending to the pile yarn feeder. As a result, the pile yarn hook 14 can be securely inserted into the gap between the ground yarn and the pile yarn. Organization A stitch can be formed in a state where the ground yarn hook 13 of the ground sinker 10 and the pile yarn are separately hooked on the pile yarn hook 14. If S2 is performed without forming a stitch with the knitting needle A in S1, the height difference between the ground yarn and the pile yarn cannot be made large.

[0018] In S2, yarn is also fed to the knitting needle j at the side end of the front knitted fabric 1f opposite the knitting end side of the rear knitted fabric 1b to form a stitch. This knitting needle j is the knitting needle located at the side end of the knitting start side of the front knitted fabric 1f when the carriage is reversed and moves leftward. With needles Here, the stitch formation with the knitting needle j has the same purpose as the knitting performed at the end of knitting in S1.

[0019] In S3, the front fabric 1f is course-knitted with the knitting needles ia except for the knitting needle j, and at the end of the front fabric 1f, yarn is also fed to the knitting needle A located at the side end of the beginning of the knitting of the back fabric 1b to form stitches. Then, by repeating the knitting shown in S2 and S3, a tubular pile fabric of the desired length can be knitted.

[0020] Although the above example shows circular knitting in a clockwise direction, it goes without saying that circular knitting in a counterclockwise direction is also possible. [Explanation of symbols]
