Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a knitting yarn,

The present invention is characterized in that, when knitting a knitted fabric using a weft knitting machine, the knitting yarn remaining end portion generated by switching the knitting yarn during knitting of the knitted fabric is loosened, To prevent unwinding of the knitting yarn.

In a knitted fabric having a stripe pattern or an intarsia pattern, the knitting yarn is switched during the knitting of the knitted fabric. In the portion where the knitting yarn is transferred, a yarn introduction portion for introducing the knitting yarn after the transfer into a knitting fabric portion knitted before the transfer is provided, and a yarn introduction portion for transferring the knitting yarn from the end of the knitting yarn portion, Out portion for pulling out the yarn, and it is necessary to prevent the knitting yarn from being loosened in the yarn inserting portion and yarn extracting portion. The applicant of the present invention has proposed a method of preventing loosening of a knitting yarn such that the loosening prevention is performed in a flat knitting machine (see, for example, Patent Document 1).

Patent Literature 1 discloses a knitting machine in which when a knitted fabric is knitted by using a weft knitting machine equipped with a knitting needle having a wing for nose movement on one side of one side of a needle body having a hook, A knot yarn break preventing method for preventing a knot yarn bridle portion from being loosened. More specifically, in the knitting width direction of each needle bed, the side on which the wing of the knitting needle is disposed is defined as the blade side, and the side on which the blade is not disposed is defined as the reverse blade side. 3].

[1] A yarn feeder is moved from a blade side to a reverse blade side, and split knitting is performed on a specific stitch, which is one of the stitches of the existing knitting needles coupled to the needle bed, The first new stitch is knitted.

[2] A second new stitch continuing in the wale direction of a specific stitch is knitted using the yarn feeder as in [1] above.

[3] The first new stitch and the second new stitch are overlapped.

Here, the split knitting is carried out by moving the stitch P, which is to be engaged with the knitting needle XX of the needle bed X, to the knitting needle YY of the needle bed Y facing the needle bed X , And knitting the stitches (Q) drawn out from the stitches (P) with the knitting needles (XX).

Japanese Unexamined Patent Application Publication No. 2014-156669

According to the method for preventing unwinding of the knitting yarn disclosed in Patent Document 1, the knitting yarn bridging portion can be reliably prevented from loosening, but if the strength of the knitting yarn to be loosened is low, the knitting yarn may be broken during the knitting prevention .

SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances described above and its object is to provide a knot loosening preventing method which is difficult to break the knitting yarn when loosening the knitting yarn bridging portion and can reliably prevent the knitting bristle portion from loosening as in Patent Document 1 .

The inventors of the present invention have variously investigated the cause of the breakage of the knitting yarn in the method of preventing unwinding of the knitting yarn of Patent Document 1. As a result, it has been found that when split knitting is performed on a specific stitch to form the first new stitch, the yarn feeder is moved from the wing side to the reverse blade side to perform split knitting. When the yarn feeder is moved from the blade side to the reverse blade side to perform the split knitting, the sinker loop of the first new stitch (the portion connecting the stitches to the stitch) is wound around the two sinker loops of the particular stitch (Refer to S1 in Fig. 1 in Patent Document 1). Since the knitting yarns are intertwined with each other, the knitting yarn is reliably prevented from loosening while the knitting yarn becomes difficult to move. Therefore, when forming a new stitch after knitting after split knitting, a large tension is applied to the knitting yarn. Based on such knowledge, the inventors of the present invention have completed the following method for preventing unwinding of the knitting yarn.

The present invention provides a knitting needle comprising a first needle bed and a second needle bed which are opposed to each other in the front and rear directions and a feeding opening for feeding the knitting yarn, the knitting needle provided on the first needle bed and the second needle bed, The present invention relates to a method for preventing loosening of a knitting yarn breakage caused by switching a knitting yarn during the knitting of a knitted fabric by using a flat knitting machine having a nose transfer bladder on one side surface of the main body. The method for preventing loosening of the knitting yarn is characterized in that when the wing side of the knitting needle is arranged on the blade side in the knitting width direction of each needle bed and the side on which the wing is not arranged is defined on the reverse blade side, A to C are provided.

A step of knitting a first stitch continuing in a wale direction of a specific stitch at a knitting position of the knitting yarn in a stitch of an existing knitting needles coupled to the first needle bed or the second needle bed;

A step of performing a split knitting on the first stitch and knitting a second stitch drawn out from the first stitch; Here, in the split knitting of the step B, the feed port is moved from the reverse blade side toward the blade side.

A step of loosening the knitting yarn brick by fixing the second stitch directly or indirectly to the first stitch;

As one mode of the method for loosening the knitting yarn of the present invention, in Step C, the second stitch is superimposed on the first stitch, and the stitch continuing in the wale direction of the double stitch is knitted, And directly fixed to the first stitch.

As a form of the method for preventing loosening of a knitting yarn according to the present invention, in step C, a third stitch continuing in the wale direction of the second stitch is knitted, the third stitch is superimposed on the first stitch, And the first stitch is indirectly fixed to the second stitch by knitting a stitch continued in the wale direction of the stitch.

In the flat knitting machine having the knitting needles having nose-moving blades, the hooks of the knitting needles of the first needle bed and the knitting needles of the second needle bed are not opposed to each other in the front face. For example, The knitting needle of the second needle bed is arranged at a position shifted to the wing of the knitting needle of the first needle bed with respect to the knitting needle of the first needle bed. Therefore, when the yarn feeder is to be moved to the wing side or the reverse wing side when the second stitch is knitted by performing the split knitting on the first stitch, the entanglement of the sinker loop of the second stitch to the sinker loop of the first stitch The method is different. In the knot loosening prevention method of the present invention, the yarn feeder is moved from the reverse blade side to the blade side to perform the split knitting on the first stitch, and the sinker loop of the second stitch, It does not get entangled as it binds two sinker loops of one stitch. Therefore, even when a new stitch is formed after the split knitting, it is difficult for locally large tension to act on the knitting yarn, so that breakage of the knitting yarn during the loosening prevention can be suppressed.

Further, according to the loosening prevention method of the knitting yarn of the present invention, it is possible to reliably prevent loosening of the knot bristles. The reason for this is that knot is formed at the knot bristle end portion as shown in the embodiment described later, by carrying out the method for preventing loosening of the knitting yarn of the present invention.

The method of preventing loosening of the knitting yarn that fixes the second stitches directly to the first stitch is particularly suitable when the yarn loading is performed, and thus the yarn introduction portion can be neatly finished.

The method of preventing loosening of the knitting yarn which indirectly fixes the second stitch to the first stitch is particularly suitable for threading, so that the yarn removing part can be neatly finished.

Fig. 3 is a knitting process diagram of the knitting loosening preventing method according to the second embodiment.

≪ Embodiment 1 >

In the first embodiment, in accordance with the knitting process chart of Fig. 1, the knitting process of the conventional knitting yarn (knitting yarn) Y1 knitted by the first knitting yarn (first knitting yarn) Y1 fed from the first feeding hole An example will be described in which the second knitting yarn Y2 that is fed from the second feeding port 9 is yarn-in with respect to the existing knitting fabric portion 10 as shown in Fig. The first knitting yarn Y1 and the second knitting yarn Y2 may use knitting yarns different in color or type. In Fig. 1, " S + number " indicates the number of knitting steps, FB indicates a front needle bed, and BB indicates a back needle bed.

The knitting needle shown in Fig. 1 is a latch needle which opens and closes a hook formed at a tip end of a needle body by swinging of a latch, And a nose-moving wing is formed on the side surface. FB and BB in the knitting width direction, the side on which the wings of the latch needles are arranged is defined as the wing side D1 and the side on which the wing is not arranged is defined as the reverse wing side D2. In the case of the flat knitting machine of this example, the right side of the paper surface of the FB is the blade side D1 and the left side of the paper is the reverse blade side D2. In BB, the left side of the paper is the blade side D1, The right side of the drawing is the reverse blade side (D2).

S0 shows a state in which the knitting yarn 10 is knitted by FB by the first knitting yarn Y1 fed from the first class sharable yarn 8. From this state, the second yarn feeder 9 for feeding the second knitting yarn Y2 is used for threading.

In S1, a stitch (a fourth stitch from the left) at a position where knitting by the knitting yarn, that is, knitting by the second knitting yarn Y2 starts, is selected as the specific stitch 11 from among the stitches of the existing knitting needles 10, Following this specific stitch 11, the knitting of a new knitting pleat continuing in the wale direction of the existing knitting needles 10 is started. The first stitch 1 is first knitted in the wale direction of the specific stitch 11 by moving the second class shoe 9 to the right side (blade side D1 in the FB) of the ground (step A) . In the case of this example in which yarn is loaded, the portion extending from the first stitch 1 in the direction opposite to the second feeding opening 9 is the knitting yarn end portion 5.

In S2, the first stitches 1, which are engaged with the knitting needles of the FB, are moved to the knitting needles of the BB facing each other. This S2 is to move the second feeding opening 9 from the reverse blade side (D2) to the first stitch (1) when knitting the next S3.

In S3, the second class shaper 9 is moved from the left side of the paper, that is, from the reverse blade side D2 to the blade side D1 in the BB, and the split knitting is performed on the first stitch 1, (Step B). Concretely, the first knitting yarn Y2 is drawn out from the first stitch 1 while the first stitch 1 coupled to the knitting needle of the BB is moved to the knitting needle of the opposing FB, The second stitches 2 are knitted on the stitches of the BB which have been formed. By performing the split knitting while moving the second class shade 9 from the reverse blade side D2 to the blade side D1 as shown in the loop diagram of Fig. 2, two sinker loops of the second stitches 2 the sinker loops 2a and 2b intersect one side portion IA of the first stitch 1 and the one side portion 1A of the specific stitch 11, The other side portion 11B which is the left side portion of the paper and the other side portion 1B of the first stitch 1 do not intersect with each other. As a result, a series of second knitting yarns Y2 running from the second grade yarn 9 to the first stitch 1 is easy to move, and it is difficult to apply a large tension locally to the second knitting yarn Y2. Here, the one side portion 11A (1A) is a part of the needle loop constituting the specific stitch 11 (first stitch 1) And the other portion 11B (1B) is a part of the needle loop constituting the specific stitch 11 (first stitch 1) ) On the moving direction side.

In S4, the second class shaper 9 is moved to the right side of the paper, and the second feeding opening 9 is stopped at a position to the right of the first stitch 1 and the second stitch 2. In S5, the second stitches 2 joined to the knitting needles of the BB are overlapped with the first stitches 1 of the FB (a part of the process C). The movement of the second class sharable yarn 9 of S4 extends from the second feeding opening 9 between the two stitches 1 and 2 when the first stitch 1 and the second stitch 2 are folded in S5, In order to prevent a part of the second knitting yarn Y2 from being caught. A part of the second knitting yarn Y2 is not sandwiched between the first stitches 1 and the second stitches 2, so that the outer shape of the stitches is neatly finished. In addition, even if a part of the second knitting yarn Y2 is sandwiched between the stitches 1 and 2 by not performing S4, the unwinding can be prevented.

In step S6, the stitches 4 continuous in the wale direction (wale direction) of the double stitch including the first stitches 1 and the second stitches 2 are knitted and the second stitches 2 are knitted 1 stitch 1, thereby preventing loosening of the knitting yarn brick 5 (the rest of the process C). The direction of movement of the second feeding opening 9 when the stitches 4 are knitted is not particularly limited. The reason why the second class shade 9 is moved to the left side (the reverse blade side D2 in the FB) in S6 and the stitch 4 is knitted is that as a result of S4, And the second-class shoe 9 is disposed on the right-hand side. If S4 is not performed, the second class shaper 9 may be moved to the right side to knit the stitches 4 in S6.

After S6, a new knitting asept continued in the wale direction of the existing knitting needles 10 may be knitted. For example, the second class shade 9 is moved to the left side to knit a new knitted fabric portion continuing in the wale direction of the existing knitted fabric portion 10.

Fig. 2 shows a loop diagram of the thread take-up unit that is prevented from being unwound by the above method. When the knitting yarn end portion 5 is pulled out from the knitted fabric after the knitting is finished, the double stitch covering the first stitch 1 and the second stitch 2 is folded, and a knot is formed at the portion surrounded by the two-dot chain line , The knot is fixed between the specific stitch 11 and the stitch 4. By forming the knot, it is possible to prevent the knitting yarn bridging portion 5 from being unwound. Since the two sinker loops 2a and 2b of the second stitch 2 intersect only with the one side portion 11A of the specific stitch 11 and the one side portion 1A of the first stitch 1, The two sinker loops of the first stitches 1 are not tightened by the sinker loops 2a and 2b of the second stitches 2 when the knot is pulled by pulling the brim end portions 5. [ This makes it easier for the second knitting yarn Y2 to move from the knitting yarn bridging portion 5 to the stitches 4, making it difficult for the second knitting yarn Y2 to be broken. A knot is not formed on the specific stitch 11 and a double stitch covering the first stitch 1 and the second stitch 2 is knotted so that the outer shape of the particular stitch 11 is not disturbed, Thus, the quality of the knitted fabric can be prevented from being impaired.

The method for preventing loosening of the knitting yarn described in the first embodiment is particularly suitable when the yarn is to be loaded, as illustrated in Fig. The stitches 4 that continue in the wale direction of the double stitch and the stitches 4 that continue in the course direction and are knitted in the course direction in succession to the stitches 4 because the double stitches covering the first stitches 1 and the second stitches 2 are broken, Is a stitch row in which the stitches substantially coincide with each other in the wale direction.

≪ Embodiment 2 >

In the second embodiment, an example of yarn-out of the first knitting yarn Y1 knitting the existing knitting yarn 10 will be described based on the knitting process diagram of Fig. The method shown in Fig. 3 is the same as in Fig.

In S1, the first class shaper 8 is moved to the right side of the paper, and the final course of the existing knitting needles 10 is knitted with the first knitting yarn Y1 (step A). In this case, the stitch that is knitted last in S1 is the first stitch 1, and the stitch of the existing knitting cloth 10 under the stitch is the specific stitch 11.

In S2, the first stitch 1, which is engaged with the knitting needle of the FB, is moved to the knitting needle of the opposing BB. In S3, the first classifying table 8 is moved toward the left side (blade side D1 in BB) of the ground, and the first stitch 1 is split and knitted, The second stitch 2 drawn out from the second stitch 2 is knitted (step B). In this case also, the two sinker loops of the second stitch 2 intersect only one side portion (the right side portion of the paper) of the specific stitch 11 and the one side portion of the first stitch 1 Therefore, the two sinker loops of the first stitches 1 are not tightened by the sinker loops of the second stitches 2. As a result, a series of first knitting yarns Y1 extending from the first-class yarn guide 8 to the first stitch 1 is easy to move, and it is difficult to locally apply a large tension locally to the first knitting yarn Y1.

In S4, the first classifying slot 8 is moved to the right to knit the third stitches 3 continuing in the wale direction of the second stitches 2 (a part of the step C). The third stitch 3 is the last stitch knitted with the first knitting yarn Y1 so that the portion extending from the third stitch 3 to the first feeding mouth 8 is the knitting yarn end portion 5 do. The second stitch 2 is fixed by knitting the third stitch 3.

In S5, the first class shaper 8 is moved to the left, and the third stitch 3 is made a twisted stitch. By making the third stitches 3 be twist stitches, the sinker loops of the third stitches 3 intersect with each other, and a frictional force is generated between the two sinker loops, so that the knitting yarn breakage part 5 becomes difficult to unravel. However, since the knitting yarn end portion 5 can be prevented from being loosened even if the third stitches 3 are not made to be twist stitches, step S5 may be omitted.

In step S6, the third stitches 3 are superimposed on the first stitches 1 (part of step C) as indicated by a thick arrow. After the step S6, a new knitting pleat continuing in the wale direction of the existing knitting needles 10 knitted with the first knitting yarn Y1 is knitted using a second knitting yarn fed from a second feeding device (not shown) . The stitch continued in the wale direction of the double stitch embedding the first stitch 1 and the third stitch 3 shown in S6 is knitted into the second knitting yarn so that the first stitch 1 and the second stitch 2 And indirectly fixed via the third stitches 3 (the remainder of the process C).

When the knitting yarn end portion 5 is pulled out from the knitted fabric after the knitting is finished, the second stitches 2 and the third stitches 3 intersect the one side portion (the right side portion of the paper) of the specific stitch 11 The two sinker loops of the second stitches 2 that are in the middle of the second stitches 2 are broken. As a result, a knot is formed on the knitting yarn brim end 5 by the method of preventing unwinding of the knitting yarn of the present embodiment, and the knot brim 5 is prevented from loosening by the knot.

The method for preventing unwinding of the knitting yarn in which the second stitches 2 are indirectly fixed to the first stitches 1 through the third stitches 3 according to the present embodiment is not particularly limited, . Since the third stitches 3 are superimposed on the back surface of the first stitch 1 when the knitted fabric is seen from the front side of the knitted fabric as seen from the front side, This is because the third stitches 3 and the second stitches 2 are not easily visible on the surface of the knitted fabric.

<Other Embodiments>

It is possible to prevent loosening of the knot bristle portion in the yarn withdrawal portion by the loosening prevention method of the knitting yarn described in Embodiment 1. [ In addition, it is also possible to prevent loosening of the knot bristle portion in the yarn introduction section by the loosening prevention method of the knitting yarn described in the second embodiment.

In the knitting loosening prevention method of the present embodiment, when the split knitting is performed on the first stitch, the spinning knitting needles may be moved from the reverse wing side of the knitting needle to which the first stitch is engaged toward the wing side to perform the split knitting. The direction of movement of the feeding opening when stitch is knitted is not limited. For example, in S1 of Fig. 1, the second feeding opening 9 is moved to the left side of the paper, and the first stitch 1 is knitted to the knitting needle of the FB. Then, without moving the first stitches 1 of the knitting needles of the FB to the opposed BBs, the second feeding opening 9 is moved to the right side of the paper to perform the split knitting on the first stitches 1, (2). In this case, the second feeding opening 9 is moved from the reverse blade side D2 of the FB toward the blade side D1 to perform the split knitting on the first stitch 1.

In addition, in the method for preventing loosening of the knitting yarn of the present embodiment, a flat knitting machine having a latch needle is used, but a method of preventing loosening of the knitting yarn is not limited to a knitting needle having a nose for moving the nose such as a compound needle ) May be used as the flat knitting machine. Further, the flat knitting machine to be used may be a four-bed flat knitting machine.
