Description

  The present invention relates to a knitting method of a pile knitted fabric capable of forming a place where there is a pile loop in the course direction of the pile knitted fabric and a place where there is no pile loop, and a sinker and a flat knitting machine suitable for the knitting method of the pile knitted fabric.

  Conventionally, a pile knitted fabric having a pile loop has been knitted by pile knitting using a flat knitting machine including a needle bed in which a plurality of knitting needles are arranged and a sinker floor in which a plurality of sinkers are arranged. ing. For example, Patent Document 1 discloses a method of knitting gloves having a pile loop by pile knitting, and a flat knitting machine for performing pile knitting.

  In pile knitting using a flat knitting machine, a ground yarn serving as a base of a pile knitted fabric is fed from a preceding yarn feeder, and pile yarns forming a pile loop are fed from a subsequent yarn feeder. The ground yarn and the pile yarn are separated by a knitting yarn locking hook provided on the knitting needle and sorted by a pile hook nail of a sinker. As a result of this sorting, a base loop, which is a sinker loop made of ground yarn, is formed on the ground thread engaging surface, which is the upper end edge surface of the sinker ground thread hook, and the upper edge of the sinker pile hook hook A pile loop, which is a sinker loop composed of pile yarn, is formed on the pile locking surface which is a surface. A pile loop larger than the base loop is formed by knit with a knitting needle while the ground yarn and the pile yarn are sorted. In this case, the pile loop is formed so as to protrude to the inside of the glove. Here, the sinker loop is a loop composed of knitting yarns connecting adjacent knit loops formed by knitting needles.

  As described above, the sinker that performs pile knitting has a function of sorting the ground yarn and the pile yarn, and a function of maintaining the state where the ground yarn and the pile yarn are sorted until the knitting by the knitting needle is finished, have. The former function is carried by the pile hooking claw of the sinker, and the latter function is carried by the pile locking surface. Here, the sinker is attached to the sinker groove of the sinker floor, and moves forward and backward along the extending direction of the sinker groove in order to press the sinker loop during knitting of the knit loop. If the pile loop easily falls off from the pile locking surface to the extent that the sinker is slightly advanced and retracted, it is difficult to maintain the state where the ground yarn and the pile yarn are sorted. Therefore, the pile locking surface is substantially parallel to the advancing / retreating direction of the sinker. When the sinker is viewed alone, the sliding contact surface that comes into sliding contact with the bottom surface of the sinker groove when the sinker is disposed in the sinker groove is parallel to the advancing / retreating direction of the sinker. Based on this sliding contact surface, the pile locking surface is substantially parallel to the sliding contact surface.

Japanese Patent Publication No. 61-20668

  In the method of knitting a pile knitted fabric of Patent Document 1, a pile knitted fabric in which a course with a pile loop and a course without a pile loop are mixed can be knitted in the wale direction of the pile knitted fabric. In order to knit a course without a pile loop, a yarn feeder that feeds each yarn may be aligned and run so that the ground yarn and the pile yarn are not sorted. However, in the knitting method of Patent Document 1, it is not possible to mix a portion having a pile loop and a portion having no pile loop on the same course.

  Therefore, one of the objects of the present invention is to provide a knitting method of a pile knitted fabric in which a portion having a pile loop and a portion having no pile loop are mixed in the same course. Another object of the present invention is to provide a sinker and a flat knitting machine suitable for the knitting method of the pile knitted fabric.

The knitting method of the pile knitted fabric of the present invention is:
When knitting a pile knitted fabric using a flat knitting machine including a needle bed having a plurality of knitting needles and a sinker floor having a plurality of sinkers,
By classifying the ground yarn from the preceding yarn feeder toward the knitting needle and the pile yarn from the subsequent yarn feeder toward the knitting needle by the sinker, the base loop constituted by the ground yarn and the pile yarn are configured. In a knitting method of a pile knitted fabric in which pile knitting is performed in which knits are performed with the knitting needles while the ground yarn and the pile yarn are sorted in a state where the pile loop is formed at different positions of the sinker.
When knitting a predetermined course of the pile knitted fabric, in addition to the pile knitting, the ground yarn and the pile yarn are once sorted in the same manner as the pile knitting, and then the ground yarn and the pile yarn are sorted. Pile cancellation knitting is performed in which knit is performed in a state where the problem is resolved.

The sinker of the present invention
A sinker that is attached to a sinker groove of a sinker floor provided in a flat knitting machine so as to freely move forward and backward, and that sorts ground yarn and pile yarn used for pile knitting, and a sliding contact surface that is in sliding contact with a bottom surface of the sinker groove, and the ground yarn In a sinker comprising a ground yarn hooking claw having a ground yarn locking surface for locking the pile yarn, and a pile hooking claw having a pile locking surface for locking the pile yarn,
The pile locking surface is inclined so as to descend toward the sliding contact surface with respect to a virtual line parallel to the sliding contact surface as it goes toward the tip, and the inclination angle is 15 ° or more and 35 ° or less. .

The flat knitting machine of the present invention
A needle bed in which a plurality of knitting needles are arranged, and a sinker floor in which a plurality of sinkers for sorting ground yarn supplied to the knitting needles from a preceding yarn feeder and pile yarn supplied to the knitting needles from a subsequent yarn feeder are arranged. In a flat knitting machine comprising:
A part of the plurality of sinkers is the sinker of the present invention.

  In the pile elimination knitting in the knitting method of the pile knitted fabric, the ground yarn and the pile yarn are sorted to form a pile loop once, and then the state where the ground yarn and the pile yarn are sorted is eliminated. When knitting with knitting yarn is performed in a state where the ground yarn and pile yarn are not sorted, the pile loop is pulled by the knitting needle, and by the advance of another sinker on both sides of the sinker to which the pile loop is locked The pile loop yarn is absorbed. As a result, the pile loop is reduced to almost the same size as the base loop. A pile loop that is approximately the same size as the base loop does not have the function originally required, but is merely a sinker loop. By performing such pile elimination knitting when the knitted fabric portion is knitted for one course, it is possible to mix a portion where there is a pile loop and a portion where there is no pile loop in the same course.

  Here, in order to mix a part with a pile loop and a part without a pile loop on the same course, it is considered to perform a knitting that does not form a pile loop without sorting the ground yarn and the pile yarn while repeating the pile knitting. It is done. However, once the separation between the ground yarn and the pile yarn is canceled and the ground yarn and the pile yarn are integrated, it is difficult to separate the ground yarn and the pile yarn again, and the surface of the pile knitted fabric is large. It may be distorted or pile knitted fabric may not be knitted. On the other hand, like the pile elimination knitting in the present invention, the ground yarn and the pile yarn were sorted in another sinker adjacent to the sinker whose sorting was eliminated by taking time and effort to form a pile loop once. The state can be maintained. As a result, the knitting after pile elimination knitting (which may be pile knitting or pile elimination knitting) can be stabilized, and disturbance of the surface of the knitted fabric portion can be suppressed.

  According to the flat knitting machine of the present invention using the sinker of the present invention, pile elimination knitting can be easily performed. This is because the pile locking surface of the sinker of the present invention is inclined so as to be lowered toward the tip, so that the pile loop once formed easily falls off the pile locking surface and moves to the ground yarn locking surface. . Since the base loop is originally locked on the ground yarn locking surface, when the pile loop is dropped on the ground yarn locking surface, the ground yarn and the pile loop are not sorted. When knitting with the knitting needle is performed in this state, the pile loop is pulled by the knitting needle and becomes smaller, and becomes almost the same size as the base loop.

FIG. 2 is a schematic configuration diagram in the vicinity of the mouth of the flat knitting machine according to the first embodiment. FIG. 2 is an explanatory diagram showing a trajectory of one knitting yarn and a trajectory of one sinker corresponding to the knitting needle during pile knitting in the flat knitting machine of FIG. 1.

It is a schematic block diagram of the normal sinker used for standard pile knitting. It is explanatory drawing which shows the latching state of the ground yarn and pile yarn in a normal sinker.

  Hereinafter, embodiments of a knitting method of a pile knitted fabric, a sinker, and a flat knitting machine of the present invention will be described with reference to the drawings.

<Embodiment 1>
In this embodiment, a schematic configuration of a flat knitting machine will be described first, and then a method of knitting a pile knitted fabric using the flat knitting machine will be described.

≪Flat knitting machine≫
A flat knitting machine 1 shown in FIG. 1 includes a pair of opposing needle beds 2, a sinker floor 4 corresponding to each needle bed 2, and a plurality of yarn feeders 8 and 9. The needle bed 2 is formed with a plurality of needle grooves 20 arranged in the depth direction of the paper (the length direction of the needle bed 2), and one knitting needle 3 is disposed in each needle groove 20. The knitting needle 3 includes a hook 31 at the tip of the needle body 30, and the hook 31 is opened and closed by a latch 32. The base of the latch 32 is provided with a knitting yarn locking hook (not shown) as in the case of the knitting needle described in Patent Document 1. The knitting needle 3 is configured to advance and retract along the extending direction of the needle groove 20 (see arrow). On the other hand, the sinker floor 4 is formed with a plurality of sinker grooves 40 in the depth direction of the paper (the length direction of the needle bed 2), and one sinker 5 is disposed in each sinker groove 40. The sinker 5 is configured to advance and retract along the extending direction of the sinker groove 40 (see arrow). In this example, the advance / retreat direction is orthogonal to the advance / retreat direction of the knitting needle 3. The knitting needle 3 and the sinker 5 are moved by a cam system mounted on a carriage (not shown) that reciprocates in the length direction of the needle bed 2.

  In the flat knitting machine 1 of the present example, as the sinker 5 described above, two sinkers 5 having different shapes (the normal sinker 5A in FIG. 5 and the modified sinker 5B in FIG. ) Is used. The normal sinker 5A is for carrying out conventional pile knitting and forming a place where a pile loop is present on the pile knitted fabric. On the other hand, the deformed sinker 5B is for carrying out unprecedented pile elimination knitting and forming a portion where there is no pile loop in the pile knitted fabric. Therefore, by replacing a part of the plurality of normal sinkers 5A arranged in the length direction of the sinker floor 4 with the deformed sinker 5B, a portion where the sinker loop is present on the same course of the pile knitted fabric may be mixed. it can. Here, any number of normal sinkers 5A may be arranged in succession, but the number of continuous deformation sinkers 5B is preferably three or less.

  In the description of the knitting method of the pile knitted fabric, which will be described later, an example in which the yarn feeders 8 and 9 are moved to the back side of the sheet of FIG. explain. In this case, the yarn feeder provided on the yarn feeder 8 on the back side of the paper is the preceding yarn feeder for feeding the ground yarn 8Y serving as the base of the pile knitted fabric, and the yarn feeder provided on the yarn feeder 9 on the front side is This is a trailing yarn feeder that feeds the pile yarn 9Y that forms a pile loop formed on the pile knitted fabric. Further, the sinker 5 shown in the figure is arranged on the back side of the drawing with respect to the knitting needle 3 and on the near side with respect to the yarn feeder 9. Here, unlike the present example, a single yarn feeder provided with a preceding yarn feeder and a trailing yarn feeder can be used.

≪Pile knitting method≫
In the knitting method of the pile knitted fabric, the pile knitting is performed when the pile knitted fabric is knitted for one course by using the flat knitting machine 1 in which the normal sinker 5A of FIG. 5 and the modified sinker 5B of FIG. 3 are arranged on the sinker floor 4. And pile-resolving organization.

[Pile organization]
The pile knitting is a knitting conventionally performed. Briefly describing the pile knitting, the knitting with the knitting needle 3 is performed in a state where the ground yarn 8Y and the pile yarn 9Y are sorted by the sinker 5.

  FIG. 2 is a diagram showing one knitting needle 3 at the time of pile knitting and the advancement state of the sinker 5 corresponding to the knitting needle 3 in chronological order from the left side of the drawing. In FIG. 2, the knitting timing at which a remarkable difference occurs in the locked state between the ground yarn 8Y and the pile yarn 9Y between the pile knitting and the pile canceling knitting described later is shown in circles A, B, C, D. It shows with. In FIG. 2, both the knitting needle 3 and the sinker 5 are drawn so as to advance and retreat in the vertical direction of the paper for easy understanding of the correspondence between the knitting needle 3 and the sinker 5, but as described with reference to FIG. 1. In addition, the actual advance / retreat direction of the knitting needle 3 and the advance / retreat direction of the sinker 5 are orthogonal to each other.

  The movement of the knitting needle 3 and the sinker 5 at the time of pile knitting is almost the same as that of the conventional pile knitting. Briefly described with reference to FIG. 2, the knitting needle 3 advances toward the tooth opening and then retracts away from the tooth opening. When the knitting needle 3 retreats, the ground yarn 8Y and the pile yarn 9Y are hooked on the hook 31 of the knitting needle 3 and pulled to the needle bed 2 side (see also FIG. 1). The reason why the degree of retraction of the knitting needle 3 is increased slightly before the timing A in FIG. 2 is that the determination is made every time the size of the knit loop is determined. On the other hand, after the knitting needle 3 starts to retract, the sinker 5 advances toward the tooth opening (see the sinker 5 indicated by the instruction line) and presses the ground yarn 8Y and the pile yarn 9Y of FIG. Thereafter, the sinker 5 once moves backward and then advances again, whereby the ground yarn 8Y and the pile yarn 9Y are sorted. Furthermore, since the sinker 5 moves backward after the timing A, the ground yarn 8Y and the pile yarn 9Y are detached from the sinker 5.

  For the pile knitting in this example, a normal sinker 5A (sinker 5) shown in FIG. 5 is used. This normal sinker 5A is a flat plate having the same thickness as that of the knitting needle 3, and is composed of a base 50, an arm 51, and an action 52 as in the conventional sinker. The base part 50 is a part accommodated in the sinker groove 40 (FIG. 1). The lower end edge surface of the base 50 along the thickness direction of the normal sinker 5A is a sliding contact surface 50s that is in sliding contact with the bottom of the sinker groove 40, and is parallel to the forward and backward direction of the normal sinker 5A. The arm portion 51 is a portion that extends in a direction protruding from the sinker groove 40 from the distal end side (tooth opening side in FIG. 1) of the base portion 50, and further bends and extends toward the tooth opening. The action part 52 is a part located on the tip side of the arm part 51 and acting on the ground yarn 8Y and the pile yarn 9Y of FIG. Of the action part 52, the part above the upper edge of the arm part 51 is a thin part 57 that is thinner than the other part.

  The action portion 52 is provided with a ground yarn hook 53 and a pile hook 55. Both the ground yarn hooking claws 53 and the pile hooking claws 55 are protrusions extending in the forward / backward direction of the normal sinker 5A. The ground yarn hooking claw 53 is located closer to the tip side (ie, the mouth side) of the normal sinker 5A than the pile hooking claw 55, and has a function of holding the ground yarn 8Y mainly during pile knitting. On the other hand, the pile hook 55 is provided at the position of the thin portion 57 and has a function of sorting the ground yarn 8Y and the pile yarn 9Y as will be described later.

  The ground yarn locking surface 53s which is the upper end edge surface of the ground yarn hooking claw 53 is a portion where the ground yarn 8Y is mainly locked, and is substantially parallel to the advancing / retreating direction of the normal sinker 5A. Further, a pile locking surface 55s, which is an upper end edge surface of the pile hook 55, is a portion where the pile yarn 9Y is mainly locked, and is substantially parallel to the advancing / retreating direction. As already described, the sliding contact surface 50s is parallel to the advancing and retreating direction. If this sliding contact surface 50s is used as a reference, both the ground yarn locking surface 53s and the pile locking surface 55s are slidable contact surfaces 50s. It is almost parallel to. In this example, both the locking surfaces 53s and 55s are inclined surfaces that are slightly lowered to the lower side (sliding contact surface 50s side) toward the tip. The inclination angles of the locking surfaces 53s and 55s with respect to a virtual line (see the two-dot chain line) parallel to the sliding contact surface 50s are 5 ° or less. That is, “substantially parallel to the sliding contact surface 50s” means “the inclination angle with respect to the sliding contact surface 50s is 5 ° or less (including 0 °)”.

  FIG. 6 shows the locked state of the ground yarn 8Y and the pile yarn 9Y in the normal sinker 5A. 6A to 6D correspond to timings A to D in FIG. As shown in FIG. 6A, in the normal sinker 5A at the timing A, the ground yarn 8Y and the pile yarn 9Y are already sorted. Specifically, the base loop 80 constituted by the ground yarn 8Y is formed on the ground yarn locking surface 53s, and the pile loop 90 constituted by the pile yarn 9Y is formed on the pile locking surface 55s. Yes.

  At timing B in FIG. 2, the knitting needle 3 is retracted more than at timing A, the old knit loop of the knitting needle 3 is knocked over, and a knit in which a new knit loop is formed is performed. At that time, the ground yarn 8Y and the pile yarn 9Y are strongly pulled by the knitting needle 3. However, as shown in FIG. 6B, the state where the ground yarn 8Y and the pile yarn 9Y are sorted is maintained, and the pile loop 90 is maintained. Is larger than the base loop 80. The above-described state is maintained because the ground yarn locking surface 53s and the pile locking surface 55s are substantially parallel to the advancing / retreating direction of the normal sinker 5A, and the yarn 8Y (9Y) extends from the locking surface 53s (55s). ) Is difficult to drop off.

  As the sinker 5 further moves backward at timings C and D in FIG. 2, the pile loop 90 falls off from the pile locking surface 55s and the base loop 80 is grounded as shown in FIGS. 6 (C) and 6 (D). It comes off from the thread locking surface 53s. At the stage of FIG. 6 (D), the pile loop 90 is at the position of the ground yarn hooking claw 53, but it is not securely locked to the ground yarn locking surface 53s. It is easily removed from the thread hook 53. Here, at timing C in FIG. 2, the knitting needle 3 has advanced a little more than at timing B. This is done to loosen the tension between the ground yarn 8Y and the pile yarn 9Y so that the pile loop 90 and the base loop 80 can easily fall off from the respective locking surfaces 55s and 53s when the sinker 5 is further retracted.

[Pile cancellation organization]
The pile elimination knitting is a new knitting that has not existed before. The pile elimination knitting will be briefly described with reference to FIG. 1. The ground yarn 8Y and the pile yarn 9Y are sorted by the sinker 5 to form a pile loop, and then the ground yarn 8Y and the pile yarn 9Y are sorted. This is a knitting in which the knitting with the knitting needle 3 is performed after eliminating the above.

  The movements of the knitting needle 3 and the sinker 5 during the pile elimination knitting are the same as those in the pile knitting described with reference to FIG. That is, it is not necessary to change the cam system that drives the knitting needle 3 and the sinker 5.

  In the pile elimination knitting, a modified sinker 5B (sinker 5) shown in FIG. 3 is used. The difference between the deformed sinker 5B and the normal sinker 5A shown in FIG. 5 is the inclination angle of the pile locking surface 55s. The inclination angle of the pile locking surface 55s of the deformed sinker 5B is not less than 15 ° and not more than 35 °. The inclination angle can be appropriately selected according to the type of knitting yarn 8Y and pile yarn 9Y and knitting conditions. If the inclination angle exceeds 35 °, it may be difficult to sort the ground yarn 8Y and the pile yarn 9Y.

  FIG. 4 shows the locked state of the ground yarn 8Y and the pile yarn 9Y in the deformed sinker 5B. 4A to 4D coincide with the timings A to D in FIG. FIG. 4A shows a locked state of the base loop 80 and the pile loop 90 in the deformation sinker 5B at the timing A. This figure shows a state in which the base loop 80 is formed on the ground yarn locking surface 53s and the pile loop 90 is formed on the pile locking surface 55s. However, since the pile locking surface 55s is inclined, the pile loop 90 is actually coming off from the pile locking surface 55s or may have already dropped.

  At timing B in FIG. 2, the knitting needle 3 is retracted more than at timing A, the old knitted loop of the knitting needle 3 is knocked over, and a new knitted loop is formed. Timing B is a timing at which the determination is completed each time the knitting needle is pulled to the lowest end and the size of a new knit loop is determined. In this example, it is assumed that the knit is completed at this timing. As shown in FIG. 4B, before the knit is completed, the pile loop 90 has already dropped from the pile locking surface 55s due to the inclination of the pile locking surface 55s, and the ground yarn 8Y and the pile yarn 9Y Sorting has been eliminated. If the inclination angle of the pile locking surface 55s is less than 15 °, there is a possibility that the sorting of the ground yarn 8Y and the pile yarn 9Y cannot be eliminated due to a slight change in humidity, temperature, and tension of the pile yarn 9Y. For this reason, it is significant to set the inclination angle to 15 ° or more.

  When the knit by the knitting needle 3 is performed in a state where the ground yarn 8Y and the pile yarn 9Y are not sorted, that is, in a state where the base loop 80 and the pile loop 90 are both locked to the ground yarn locking surface 53s. Is pulled by the knitting needle 3. Further, the advancement of another sinker 5 on both sides of the sinker 5 to which the pile loop 90 is locked absorbs the knitting yarn of the pile loop 90 and becomes smaller, so that the pile loop 90 is almost the same size as the base loop 80. become. Therefore, when the sinker 5 further moves backward at the timings C and D in FIG. 2, as shown in FIGS. 4C and 4D, the ground yarn of the deformed sinker 5B with the base loop 80 and the pile loop 90 overlapped with each other. It comes off from the locking surface 53s. The pile loop 90 having almost the same size as the base loop 80 does not have the originally required function, but is merely a sinker loop.

≪Effect≫
By performing the pile knitting and the pile elimination knitting described above when the pile knitted fabric is knitted for one course, a portion where the pile loop 90 is present and a portion where the pile loop 90 is not present can be mixed.

≪Comparative example≫
Here, in addition to the knitting method shown in the first embodiment, the following two knitting methods were tried as a knitting method in which a part having a pile loop and a part having no pile loop are mixed in the same course.
(1) The deformed sinker 5B was pulled out of the sinker floor 4 and a pile knitted fabric was knitted.
(2) The deformed sinker 5B was replaced with a sinker without the pile hook 55, and a pile knitted fabric was knitted.
However, it was found that the surface of the pile knitted fabric was greatly disturbed by any knitting method. The knitting methods (1) and (2) are knitting methods in which the ground yarn 8Y and the pile yarn 9Y are not sorted in order to form a portion without a pile loop. If the sorting of the ground yarn 8Y and the pile yarn 9Y is stopped while the pile knitting is repeated, the ground yarn 8Y and the pile yarn 9Y are integrated, and it is difficult to separate the ground yarn 8Y and the pile yarn 9Y again. It is presumed that it is.
