Description

  The present invention relates to a method for knitting a knitted fabric having shrinkage resistance.

In general, knit products, especially knitted fabrics such as knitted fabrics, are knitted in a state where loops are chained together. There is a problem that it is easy to shrink because of the repeated.
However, synthetic fibers have a low hygroscopic property, and when sweated, there is a problem that the skin is stuffy, and in the case of hypersensitive skin, rough skin or rash may occur depending on the material of the knitting yarn.
Further, when natural fibers such as cotton yarn having hygroscopicity are used for the knitting yarn, the above problem can be prevented as much as possible, but there is a problem that the knitted fabric gradually shrinks every time it is washed.

In order to prevent such loss of shape and shrinkage of the knitted fabric, it is effective to reduce the size (degree) of the loop.
The setting of the second time is performed by the amount by which the knitting needle is drawn by the second cam (stitch cam) as shown in, for example, Patent Document 1, but when forming a small loop, the old loop knocks over the hook portion. It must be smaller than the size that can clear the hook, and there is a limit depending on the type of thread.
Although it is conceivable to increase the tension of the knitting yarn to be fed, in such a case, yarn breakage frequently occurs and is not practical.
Therefore, in general, the knitting yarn count and tension suitable for the gauge and the minimum value of the stitch are substantially determined by the gauge of the knitting machine.

  The present invention has been proposed in view of the above-mentioned problems, and has a shape prevention effect and shrinkage resistance by forming a smaller loop than a small loop within a general range having little shape loss and having a shrinkage prevention effect. The object is to provide a knitting method for the knitted fabric.

  In order to achieve the above object, the knitting method for shrink-proof knitted fabric according to the present invention includes a plurality of knitting needles housed in a needle bed so as to be slidable back and forth with a cam of a carriage. In the knitting method of the knitted fabric to be knitted, among the knitting needles in the knitting area of the knitted fabric, the knitting needles at predetermined intervals are selected, the selected knitting needles are fed, and the knitting needles between them are removed. After forming the loop in the state and making the knitting yarn in the needle removal portion into the transition yarn state, the knitting needle in the transition yarn portion is driven up and down, and the old loop is knocked over to form a loop with the transition yarn on the knitting needle. By forming a loop with this crossover yarn, the most important thing is to pull back the knitting yarn from the previously formed loop, and to give shrinkage to the knitted fabric at a degree smaller than the loop at the time of knitting. Main features.

  Further, in the knitting method of the knitted fabric having shrinkage resistance according to the present invention, a plurality of cams for raising and lowering the knitting needles are provided on the carriage, and the cams on the leading side in the sliding direction of the carriage are selected at predetermined intervals. It is also characterized in that a knitted fabric is knitted as a lifting drive cam and a trailing cam is used as a lifting drive cam for a knitting needle of a cross yarn portion to impart shrinkage resistance to the knitted fabric.

  Furthermore, in the knitting method of the knitted fabric having shrinkage resistance according to the present invention, the knitting needle housed in the needle bed is a circular knitting machine in which the cylinder needle and the diamond needle are provided with a relatively different half pitch, It is also characterized in that either one of the knitting needles of the diamond needle forms a loop in a needle-removed state, and the knitting yarn between the knitting needles is formed with a loop with the other knitting needle, thereby imparting shrinkage resistance to the knitted fabric. It is what.

  In the knitting method of the knitted fabric according to the present invention, among the knitting needles in the knitting area of the knitted fabric, the knitting needles at predetermined intervals are selected, the selected knitting needles are fed, and the knitting needles between them are in a needle-free state. After forming the loop with the knitting yarn in the needle removal portion, the knitting needle in the transition yarn portion is driven up and down to form a loop with the knitting needle, and the loop is formed with the transition yarn. Sometimes, by pulling back the knitting yarn from the previously formed loop, it is possible to make the stitches smaller than the stitches that are generally regarded as appropriate loops.

  Therefore, according to the knitting method of the knitted fabric of the present invention, the loop smaller than the minimum degree within the suitable range, which has been considered difficult so far, can be knitted satisfactorily without knitting and cutting out of shape. There is an advantage that a sheet for forming a ventilation gap can be produced which produces a knitted fabric having effects and shrinkage resistance.

  Hereinafter, specific examples according to the knitting method of the knitted fabric having shrinkage resistance according to the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory diagram in the case of knitting a general flat knitted fabric with a cylinder needle of a circular knitting machine, and reference numeral 1 in the drawing indicates a cylinder (needle bed).
A plurality of needle grooves 2 are engraved at equal intervals along the axial center of the cylinder 1 on the outer peripheral surface portion of the cylinder 1, and each of the needle grooves 2 has a Bella type knitting needle (latch needle) 3. It is stored so that it can slide up and down.
These knitting needles 3 are provided with long knitting needles (long needles) from the hook 4 to the needle bat 5 and short knitting needles (short needles) from the hook 4 to the needle bat 5 alternately. The bat 5 of the knitting needle 3 selected in (1) is slid up and down by the cam group 7 of the carriage 6 that slides on the outer periphery of the cylinder 1, so that the stitch is knitted by the knitting 8 fed from a yarn feeder (not shown). 9 is formed.

  The cam group 7 of the carriage 6 is arranged with a long needle track for moving up and down a long knitting needle and a short needle track for moving up and down a short knitting needle in a state shifted in front and back, and each track has a chevron shape. A clearing cam (needle lasing cam) 11 and a guard cam 12 and a stitch cam 13 corresponding to the mountain cams provided at the front and rear of the clearing cam 11 and between the clearing cam 11, the stitch cam 13 and the guard cam 12. Is formed.

That is, as shown in FIG. 1, when the carriage 6 slides from the left to the right around the cylinder 1, the needle bat 5 of the selected knitting needle 3 moves to the track 10 between the clearing cam 11 and the guard cam 12. When the spatula 15 is gradually lifted by the old loop 14 which is going to be stopped by the tension of the knitted fabric, and the knitting needle 3 starts to descend with the stitch cam 13 after further rising, the feed from the yarn feeder (not shown) is fed. The threaded knitting yarn 8 is hooked on the hook 4.
When the knitting needle 3 further descends, the old loop 14 closes with the hook 4 holding the knitting yarn 8 and then the old loop 14 clears (hooks over) the hook 4 portion, so that a new loop 16 is formed in the hook 4 portion. Is done. A knitted fabric is formed by repeating these operations.

Next, a method for knitting a knitted fabric having shrinkage resistance according to the present invention using the above-described general circular knitting machine will be described.
First, when the carriage 6 slides from the left to the right around the cylinder 1 as described above, the needles A, C, E... Are selected as shown in FIGS. The knitting needles 3 of B, D, F,... Are paused and fed to the selected knitting needle 3 to form a loop. At this time, the lowering amount of the knitting needles A, C, E,... Is minimized so that the old loop can clear the hook portion.
Further, the selection of the knitting needles (3) A, C, E,... Is made by alternately arranging the long knitting needles 3 and the short knitting needles 3 as in this example, and selects one of the knitting needles 3 and the other. The knitting needle 3 can be used for pause.
A knitting yarn 8 having loops formed at both ends is stretched in the state of a crossover yarn 17 on the knitting needle (3) B, D, F.
In the perspective view of FIG. 2, the loop portion is shown to be extremely extended in order to clarify the relationship of the knitting yarn 8.

Next, the knitting needles (3) B, D, F,... Are selected, and the knitting needles (3) B, D, F,... Are tracked between the clearing cam 11, the stitch cam 13, and the guard cam 12. When the elevating drive is performed by the (sliding groove) 10, as described with reference to FIG. 1, the old loop 14 having opened the spatula 15 is opened and comes out of the spatula 15, and then the transition yarn 17 is fed to the hook 4.
After that, the knitting needles (3) B, D, F... Holding the yarn over the hook 4 are lowered, but the lowering amount of the knitting needles (3) B, D, F. ) Similar to the descending amount of A, C, E,..., The minimum descending amount is sufficient for the old loop 14 to clear the hook 4 portion.
Thus, when the knitting needle (3) B, D, F... Is lowered, the old loop 14 clears the hook 4 portion, and a new loop 16 is formed in the hook 4 portion by the transition yarn 17.

When the knitting needle (3) B, D, F... Holding the transition yarn 17 descends and a new loop 16 is formed, the knitting needle (3) A, C, E. Since the knitting yarn 8 is pulled back from the loop 18 that has been formed, the knitting yarn 8 is moved from the new loop 16 after the knitting needles (3) B, D, F. 3) Pull back to A, C, E ... again.
As a result, when the loops 18 and 16 of the knitting needle 3 are leveled, the loop becomes smaller than the minimum degree of the aptitude range that has been considered difficult so far.
Further, when the loop 18 is formed on the knitting needles (3) A, C, E,..., The knitting needles are within a general allowable knitting range, and the knitting needles (3) B, D, F,. In the case where the new loop 16 is formed with the crossover yarn 17, the knitting yarn 8 is drawn from the previously formed loop 18 as described above, so that it can be knitted well without being broken.

Although the above example has been described with flat knitting, it can also be applied to rib knitting as shown in FIGS.
In the rib knitting in the circular knitting machine, the knitting needle 3 on the cylinder side and the knitting needle 20 on the dial side are used for knitting. The uppercase letters in FIGS. 5 and 6 indicate the knitting needle 3 on the cylinder side, and the lowercase letters are A dial-side knitting needle 20 is shown, and the cylinder-side knitting needle 3 and the dial-side knitting needle 20 have a structure of a general circular knitting machine in which the phases are relatively shifted by a half pitch.
First, as shown in FIG. 5, the knitting needles (3) A, B, C, D... On the cylinder side are selected and the knitting yarn 8 is supplied by the yarn feeder to loop the front knitting portion (front knitting). Form.

Next, as shown in FIG. 6, the cylinder side knitting needles (3) A, B, C, D... Are stopped, and the dial side knitting needles (20) a, b, c, d. The dial-side knitting needles (20) a, b, c, d... Hook the knitting yarn 17 that is a transition yarn between the cylinder side knitting needles (3) A, B, C, D. In step 4, the old loop 18 is cleared to form a new loop 16 in the back knitting portion.
Then, as shown in FIG. 7, 1 × 1 rib knitting in which front knitting and back knitting are alternately arranged is formed.
Here, the knitting needle 3 on the cylinder side and the knitting needle 3 on the cylinder side are formed like the conventional rib knitting which forms the front knitting and the back knitting substantially simultaneously by shifting the knitting time of the front knitting portion and the back knitting portion as in this example. The knitting needle 8 is not attracted simultaneously with the knitting needle 20 on the dial side, and a loop smaller than the minimum degree of the suitable range, which has been considered difficult so far, can be knitted well without causing yarn breakage.

In each of the above embodiments, the circular knitting machine is described as an example. However, the present invention is not limited to this, and the flat knitting machine knitting machine can also be applied to the knitting structure. Of course, it is not limited to flat knitting or rubber knitted fabric.
The knitting needle is not limited to a latch needle, and it goes without saying that the present invention can be applied not only to a compound needle provided with a slider but also to a whisker needle.
