Abstract

PROBLEM TO BE SOLVED: To improve the binding stitch knitting and provide a method for knitting by which the shrinkability of a part of a knitted fabric where the knitting is completed is raised. SOLUTION: The binding stitch treatment of each stitch is successively carried out from one end of a prescribed section on a needle bed as a starting point toward the other end for a stitch of a knitted fabric knitted by using a flat knitting machine in the final course engaged with knitting needles in the prescribed section. In the process, the stitch formed when carrying out the binding stitch treatment is formed by feeding a knitting yarn in the direction opposite the forward direction of the binding stitch treatment. The knitted fabric undergoing the binding stitch treatment is the one composed of a 1×1 rib stitch textile design and the binding stitch treatment is performed with an elastic yarn. The stitch formed at that time is a purl stitch.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in bind-off processing applied to an end portion of a knitted fabric knitted by a flat knitting machine.

[0002]

2. Description of the Related Art A bind-off processing method is known as an anti-loosening process for the end portion of a knitted fabric of a knit product such as a sweater. As a method of performing this bind-off processing with a flat knitting machine, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 2-91254 by the present applicant. The bind-off processing is performed by forming a new stitch following the stitch on one end side of the bind-off processing portion of the final course, and then overlapping the formed stitch with the stitch of the adjacent final course. The stitches of the final course are released from the knitting needles by sequentially performing toward the end side. In the conventional bind-off processing method including the above-mentioned publication, the stitches formed in the bind-off processing are in the advancing direction of the bind-off processing, that is, the bind-off processing is located on the right side of the stitches located on the left side of the final course. When advancing toward the stitch, the knitting yarn was supplied and formed in the same direction as the advancing direction. Therefore, the stitch formed has a normal loop structure.

The hem and collar of a sweater are often knitted with a rib knitting structure of 1 × 1 or the like, but when knitting is done so that the part becomes the knitting end part, the conventional method shown above is used to lay it down. When the eye treatment is performed, the shrinkage of the bind-off portion is lost, and the knitting end portion of the knitted fabric opens like a trumpet. Further, in order to increase the shrinkage, a bind-off treatment may be performed using an elastic yarn, but it has been difficult to obtain a satisfactory shrinkage.

When a sweater or the like is knitted on a flat knitting machine as a non-sewn knit, the end portion of the tubular knitted fabric is sequentially subjected to a bind-off process in a circular shape. The stitches are sequentially released from the needles by the bind-off process, and when the number of stitches increases, the weight of the knitted fabric affects the bind-off knitting, and the size of the formed stitches gradually increases. There is a problem that the difference between the size of the stitch and the size of the stitch at the end point becomes remarkable, and the appearance of the product is impaired.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a knitting method in which the bind-off knitting is improved to enhance the shrinkability of the knitting end portion of the knitted fabric.

It is another object of the present invention to provide a bind-off processing method which is adopted for the knitting end portion of a knitted fabric which is knitted as a collar portion such as a hem portion or a round neck which requires elasticity.

Another object of the present invention is to provide a method for making uniform the sizes of the stitches formed at the bind-off of the end portion of the tubular knitted fabric.

[0008]

According to the present invention, with respect to the stitches of the final course which are held by the knitting needles of a predetermined section on the needle bed of the knitted fabric, one end of the section is the starting point and the other end is directed toward the other end. In the method of sequentially performing the bind-off processing on each stitch, the stitches formed at the bind-off are formed by supplying the knitting yarn in the direction opposite to the traveling direction of the bind-off processing. Since the stitch formed in this way is in a twisted state, the stitch size in a natural state is small, and as a result, the shrinkage degree of the bind-off portion is increased and the tightness of the knitting end portion of the knitted fabric is conventionally reduced. Is increased compared to. The number of knitted fabrics to be turned down is 1
In the case of the knitted fabric having the rib knitting structure of × 1, the shrinkage degree of the knitting end portion of the hem and the collar can be further increased by performing the bind-off process using the elastic yarn. When the stitch formed at that time is used as the back stitch, this portion is hidden on the back side of the knitted fabric and is not conspicuous.

Further, the tubular knitted fabric is subjected to a bind-off processing in a circular shape, and at the time of the bind-off processing of each knitted fabric, the starting point side thereof is locked to the needle on the needle bed and each of the starting point side is held. After performing the bind-off processing on the stitches in sequence, the lock on the starting side is released. As a result, even if the stitch is released from the needle during the bind-off process, the weight of the knitted fabric does not adversely affect the stitch formation, and the stitch having a uniform size is formed.

Further, the knitted fabric is locked on the needle bed by hooking a knitting yarn with a needle or by splitting and stitching a stitch on the needle, and the needle bed of the locked knitted fabric. The release from the knitting machine is not required because the knitting operation is performed by the knitting operation such as the payment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the bind-off processing method of the present invention will be described below with reference to the drawings. The flat knitting machine used is a so-called two-bed flat knitting machine with a pair of front and rear needle beds facing each other. Further, the front stitch means a stitch that appears as a front stitch when viewed from the knitted fabric surface side, and the back stitch means a stitch that appears as a back stitch when viewed from the knitted fabric surface side, and the stitch formed during the bind off treatment is the back stitch. To do.

<Embodiment 1> In the present embodiment, 1 ×
A bind-off process is performed on a single-layer knitted fabric having a 1-rib knit structure. The bind-off processing is sequentially performed from the left to the right on the paper after the final stitch course knitting of the knitted fabric. FIG. 1 shows a knitted fabric 1 to be knitted, and FIG. 2 shows a knitting block diagram of a knitting end portion. The stitches to be formed may be front stitches or back stitches, but by forming them as back stitches, the portions are hidden on the back surface side of the knitted fabric. The front stitches are formed by the front needle beds and the back stitches are formed by the rear needle beds. The number on the left side of FIG. 1 indicates the number of the knitting block, and the arrow next to it indicates the moving direction of the yarn supplying member. F and B indicate the front needle bed and the rear needle bed. The alphabets shown at the bottom of the figure indicate the needles on the needle bed. The number of stitches used for knitting the fabric is set smaller than the actual number of stitches for convenience of description.

First, in the block 1, the knitting yarn 5 is made by the yarn supplying member 3.
Are alternately supplied to the needles a, b, c, ..., H, i, j of the front and rear needle beds to knit a stitch course 7 of a knitted fabric 1 having a 1 × 1 rib knitting structure. In the subsequent block 2, the knitting yarn 5 is supplied to the needles j, i, h, ... The knitting of the stitch course 9 as a course is performed.

Blocks 3 to 6 indicate that each stitch of the final course 9 of the knitted fabric 1 which is locked by the needles of the front and rear needle beds is sequentially knitted from the left to the right. In the block 3a, the yarn supplying member 3 is first moved rightward to a position beyond the needle a in order to bind off the stitch 11 held by the needle a of the rear needle bed. Next, the knitting yarn 5 is fed to the needle a while reversing the yarn feeding member 3 to form the stitch 13 (block 3b).
Next, in block 3c, the stitch 13 is transferred to the needle b on the front needle bed that locks the stitch 15 on the right side, to form a double stitch. As a result, the stitches held by the needle a of the final course are subjected to bind-off processing and released from the needle. As shown in the block 3b, the stitches formed during the bind-off processing are fed in the direction opposite to the advancing direction of the bind-off processing, that is, the bind-off processing is advanced from left to right. Since the formed stitches are formed by supplying the knitting yarn from the right to the left, the formed stitches are in a twisted state. When all the stitches formed during the bind-off processing are formed in a twisted state, the stitch size in the natural state becomes small, and as a result, the shrinkage of the bind-off portion increases and the knitting of the knitted fabric The tightness of the end portion is increased as compared with the conventional one.

Block 4 shows the bind-off stitch knitting of the stitches held by the needle b of the front needle bed. First, the double stitches locked by the needle b are transferred to the needle b on the opposite rear needle bed (block 4
a), the yarn supplying member 3 is moved to a position beyond the needle b (block 4b). Next, while moving the yarn supplying member 3 from the right to the left in the block 4c, the knitting yarn 5 is supplied to the needle b and the back stitch 1
7 is formed. The back stitch 17 is once an empty needle c on the front needle bed.
And then move to the needle c of the rear needle bed
(Block 4d, e). This completes the bind-off processing of the stitches held by the needle b.

By performing the same knitting as in the above blocks 3 and 4 on the subsequent blocks 5 to 6, the needles c, d, ...
The stitches of the final course of the knitted fabric 1 held by h and i are subjected to the bind-off process in sequence. The block 6c is a stitch 2 formed during the bind-off processing of the stitch 21 that has been retained by the needle i of the rear needle bed.
3 shows a state in which the needle 3 of the front needle bed is moved to make a double stitch. After the bind off processing of the stitches held by the needle i is completed, after the yarns are fed to the needle j of the rear needle bed in blocks 7 to 9 to form new stitches 26, 27, 28 following the stitch 25. Block 10
Then, the stitch 28 is removed from the needle, and the knitting of the knitted fabric 1 is completed.

<Modification> In the present embodiment, the bind-off knitting of the knitted fabric end portion of the tubular knitted 1 × 1 rib knitting structure will be described. A knitting technique for a tubular knitted fabric having a mixture of front stitches and back stitches using a two-bed flat knitting machine or a four-bed flat knitting machine is known, and for example, Japanese Patent Publication No.
No. 75656, Japanese Patent Publication No. 3-16415, and the like. FIG. 3 shows a tubular knitted fabric 41 in which a front body 41f and a back body 41b are connected at a side end of a knitting width, and FIG. 4 shows a knitting block diagram thereof by a two-bed flat knitting machine. The knitting of the front body 41f is performed using the needles b, d, f, h, j, l, and the rear body 41f
The knitting of b is performed using needles c, e, g, i, k, and m. The stitches appearing as the front stitches on the surface side of the tubular knitted fabric 41 are formed by the needles b, f, j of the front needle bed and the needles c, g, k of the rear needle bed, and the stitches appearing as the back stitches are those of the front needle bed. Needles d, h, l,
It is formed by the needles e, i, m of the rear needle bed.

In the block 1, the knitting yarn 47 is made by the yarn feeding member 45.
Are supplied to the left, and the course 43 of the front body 41f is knitted. During the knitting of the front body 41f, the stitches of the back body 41b are in a state of being held by the needles of the back needle bed. Block 2 is the predecessor 41
After finishing the course knitting of f, the back stitch formed by the needles d, h, l of the front body is returned to the front needle bed (block 2a) and the needles e, i of the rear needle bed for the back stitch knitting of the succeeding body 41b. , M are transferred to the front needle bed (block 2b). Block 3 shows the knitting of the course 49 (final course) of the back body 41b, during which the stitches of the front body 41f are in a state of being held by the needles of the front needle bed. In the block 4, the stitches are transferred in the same manner as the block 2, and preparation for the subsequent course formation is made. Block 5 shows the course organization of the final course 51 of the predecessor 41f.

Blocks 6 to 18 show knitting in the bind-off processing. In the present embodiment, the bind-off processing first performs the bind-off knitting for each stitch of the final course 51 of the front body 41f sequentially from left to right in the drawing. After that, the stitches of the final course 49 of the back body 41b are successively turned off from right to left. Blocks 6 to 10 perform the bind-off processing of the predecessor 41f, block 11
-18 shows the bind-off processing of the back body 41b. While the bind-off knitting of the front body 41f is performed, the stitches of the back body 41b are kept in a state of being held by the needles of the back needle bed. In addition, the stitches formed during the bind-off processing are back stitches as in the above embodiment.
In the present embodiment, the bind-off knitting is performed using elastic yarns of high elongation such as Woolly nylon (trademark) and Marlon (trademark). In the block 6a, the stitch 57 locked to the needle b of the front needle bed is transferred to the needle b of the rear needle bed. In the block 6b, the yarn supplying member 53 having the elastic yarn 55 is used in place of the yarn supplying member 45 which has been used so far, and is moved to a position beyond the needle b of the front needle bed. Next, the yarn supplying member 5
3 is moved to the left to form the stitch 59 following the stitch 57, and at the same time, the stitch is hooked on the needle a which is not locked, and the starting side of the bind-off process is fixed on the needle bed (block 6c). As a fixing method, instead of the hooking method, the stitch 57 may be divided into two and one of the divided stitches may be hung over the other needle. Specifically, split knitting, transfer knit, split knit This can be done using the so-called widening technique called etc. By performing the subsequent bind-off process with the starting side of the bind-off process hooked to the needle, even if a large number of stitches are released from the needle, the effect of the weight of the knitted fabric can be dispersed Since the stitches are formed as a reference, an appropriate tension can be applied to the stitches, and formation of stitches of uniform size is allowed. Continued block 6
In d and e, the formed stitch 59 is moved to the needle d on the rear needle bed that locks the stitch 61 on the right side, and the stitch is moved to form a double stitch. As a result, the stitches held by the needle a of the final course are subjected to bind-off processing and released from the needle. Block 7 shows the bind-off stitch knitting of the stitch 61 that is locked to the needle d of the rear needle bed. The yarn supplying member 53 is moved to a position beyond the needle d (block 7a), the knitting yarn 55 is supplied to the needle d while moving the yarn supplying member 53 from the right to the left in the block 7b, and the stitch 63 is formed. The stitch 63 moves to the needle f on the front needle bed and is overlapped with the stitch 65 (block 7c). This completes the bind-off process of the stitches held by the needle d.

A knitting similar to the above is applied to the needles f of the front body 41f,
This is performed for h, j, and l and the bind-off processing of the final course 51 is performed. Block 9 shows the bind-off processing of the stitch 67 at the right end of the front body 41f, and the stitch 69 formed in this block for continuing the knitting of the subsequent back body 41b is the stitch at the right end of the final course 49 of the back body 41b. After locking 71, it is transferred to the needle m on the needle bed to form a double stitch. At this point, the bind off of the final course 51 of the front body 41f is completed, and the knitting yarn hooked at the block 6c at the block 10 is blown off from the needle.

Next, the bind-off processing of the rear body 41b is block 1
It will be described from 1 onward. All the stitches of the final course 49 of the back body b are kept in a state of being locked by the needles of the back needle bed. When the knitting of the block 9 is completed, the yarn supplying member 53 is already positioned on the advancing direction side of the bind-off, so that in the block 11a, the elastic yarn 55 is supplied to the needle m while moving the yarn supplying member 53 to the right to form the stitch 73. At the same time as forming, the empty needle n is hooked. The hooking of the knitting yarn to the empty needle is performed for the same purpose as in the block 5. Next, the formed stitch 73 is transferred to the needle k of the front needle bed and then transferred to the needle k of the rear needle bed in order to overlap the stitch 75 on the left side. As a result, the stitches held by the needle m of the final course are subjected to bind-off processing and released from the needle.

In the block 12, the yarn supplying member 53 is moved to a position beyond the needle k (block 12a), and the block 1
In 2b, the yarn supplying member 53 is moved from left to right to supply the elastic yarn 55 to the needle k to form the stitch 77. The stitch 77 is moved to the needle i of the front needle bed, and then transferred to the needle i of the rear needle bed, and the stitch 79
(Blocks 12c and 12d). Such knitting is performed on the following blocks 13 to 14. When the knitting of the block 14 is completed, the stitch 83 is overlapped with the stitch 85 locked by the needle c located at the left end of the final course of the back body 41b. In blocks 15 to 17, after the stitches 87, 88, 89 following the stitch 85 of the final course are formed, the block 18
Then, the knitting yarn hooked by the stitch 89 and the block 11a is released from the needle, and the knitting of the knitted fabric 41 is completed.

FIG. 5 shows an example in which the bind-off processing of the present invention is applied to knitting of a sweater, the arrow indicates the knitting direction, and P indicates the bind-off processing portion. In the case of so-called reverse knitting in which knitting starts at the shoulder and ends at the hem as shown in FIG. 5a, the bind-off processing portion appears at the lower end of the hem of the sleeve and the body, and in the case shown in FIG. Appears at the top of the collar. Although the above description has been given of the example of the two-bed flat knitting machine, it goes without saying that
It can also be applied to a single-bed flat knitting machine. Further, the applicable knitting structure is not limited to 1 × 1 rib, and may be plain knitting or other rib knitting.

[0024]

As described above, since the stitches formed in the bind-off stitch are formed by supplying the knitting yarn in the direction opposite to the advancing direction of the bind-off stitch, the stitch formed is in a twisted state, and the stitches are divided by that amount. Will be reduced and the degree of shrinkage of the bind-off processing portion will be increased.

Further, when the bind-off processing of the knitted fabric having the 1 × 1 rib knitting structure is performed with the elastic yarn, the tightness is increased as compared with the case of the bind-off with the conventional elastic yarn. It is advantageous.

Further, even if a loop-off is made from one knitted fabric of the tubular knitted fabric to the other knitted fabric, since the starting side of each knitted fabric is fixed to the needle on the needle bed, Since the size of the stitches at the end can be made substantially uniform, the appearance is not spoiled as in the conventional case.

Further, since the knitted fabric is locked and released by using the needles on the needle bed, it is not necessary to provide a special device on the knitting machine side.
