  This embodiment will be described with reference to FIGS. The manufacturing method of the knitted lace fabric of this embodiment includes a knitting step for knitting a warp knitted fabric, a dyeing process for dyeing and heat-setting the knitted warp knitted fabric, and a warp knitted fabric in order of steps. A cutting step for obtaining a plurality of knitted fabrics. Below, each process is demonstrated.

  In the following description of the knitting process, the left-right direction, the width direction of the warp knitting machine, and the width direction of the warp knitted fabric are the same direction.

  As a warp knitting machine used in the knitting process of the present embodiment, for example, a single raschel machine can be used. The warp knitting machine includes a plurality of knitting needles arranged in a line in the width direction. The warp knitting machine includes a plurality of ridges (also referred to as guide bars) arranged in the front-rear direction, and each ridge includes a plurality of guides arranged in a line in the width direction of the warp knitting machine. Each of the plurality of guides guides the yarn toward the knitting needle. The plurality of scissors include at least a ground scissors for guiding the ground yarn and a handle scissors for guiding a cutting yarn described later. An example of such a knitting unit is shown in FIG. In FIG. 1, as a plurality of ridges, in order from the front, one ground ridge 10, one pattern ridge 11, two jacquard ridges 12 and 13, multiple pattern ridges 14, one ground ridge 15, Are lined up. A drop plate (not shown) may be provided.

  In the ground rods 10 and 15 and the handle rods 11 and 14, the plurality of guides provided in the respective rods move together according to the movement of the rods. The jacquard rods 12 and 13 are provided with a plurality of jacquard guides arranged in a line in the width direction of the warp knitting machine. A plurality of jacquard guides provided on one jacquard ridge 12 (or 13) move together according to the movement of the jacquard ridge 12 (or 13), respectively, It can be independently displaced in either the left or right direction.

  As will be described later, for example, the ground rod 10 has a ground yarn 56, the handle rod 11 has a heat-sealing yarn 55, the jacquard rods 12, 13 have a plurality of jacquard yarns 50, 51, 52, 53. The handle 14 is used to guide the cutting yarn 54 and the handle yarn, and the ground 15 is used to introduce the elastic yarn.

  The warp knitted fabric 30 shown in FIG. 2 is knitted by the warp knitting machine exemplified in this way. In the knitting of the warp knitted fabric 30, the plurality of product parts 31 are knitted so as to be arranged in the width direction. Disposable portions 32 are provided between the product portion 31 and the product portion 31 and on both sides in the width direction of the warp knitted fabric 30. Therefore, the product part 31 and the discard part 32 are provided adjacent to each other in the width direction. The plurality of product sections 31 and the plurality of discard sections 32 are knitted as one warp knitted fabric 30. In addition, the product part 31 is a part taken out as the knitted lace fabric 33 in a cutting process described later, and the discarding part 32 is a part removed in the cutting process.

  A boundary 34 between the product portion 31 and the discard portion 32 is scalloped and extends in the wale direction. Accordingly, the end of the product portion 31 in the width direction has a scalloped shape. The scalloped shape is a shape that extends in the wale direction while bending left and right. The scalloped shape includes a wave shape (FIG. 3A) and a curved portion 35 and no corner portion 36, and an arc continuous shape in the wale direction (FIG. 3B). A shape having the curved portion 35 and the corner portion 36, a shape having the corner portion 36 without the curved portion 35, such as a zigzag shape (FIG. 3C), and the like are included.

  The knitting of the warp knitted fabric 30 will be described in more detail. FIG. 4 shows a warp knitted fabric 30 in which the product portion 31 and the discard portion 32 are integrated. In the knitting of the warp knitted fabric 30, a part on the product part 31 side from the boundary 34 (shown by a broken line in FIG. 4) between the product part 31 and the discarding part 32 is at least a certain length in the width direction. Knit as a net part 40 which is a net-like part. In other words, a portion having a constant width including at least the width direction end portion of the product portion 31 is knitted as the net portion 40. The net shape is a state in which the plurality of through holes 41 are two-dimensionally expanded. The through-hole 41 is a hole through which the other side of the warp knitted fabric 30 can be seen when the warp knitted fabric 30 is viewed from a direction perpendicular to the surface thereof.

  Although the structure of the net part 40 is not limited, for example, as shown in FIG. 5 (a), the ground yarn 56 guided by the ground cloth 10 is chain knit that forms stitches with the same wale. Further, the jacquard yarns guided by the jacquard ridges 12 and 13 are inserted in the horizontal direction so as to connect the adjacent wales of the chain knitting in a predetermined course.

  A specific example of the knitting by the jacquard rods 12 and 13 in this example is shown in FIG. In the knitting shown in FIG. 5 (b), the yarns are introduced to the two jacquard rods 12 and 13 serving as offsets so that the entire jacquard rods 12 and 13 are fully aligned. . Then, the jacquard yarns 50 and 52 are introduced by the jacquard rod 12, and the jacquard yarns 51 and 53 are introduced by the jacquard rod 13.

  Then, as shown in FIG. 6, the two jacquard rods 12 and 13 are moved so as to insert the jacquard yarns in a zigzag shape. Further, while performing the motion of FIG. 6, the jacquard mechanism is operated to displace each jacquard guide along a predetermined course. As a result, the knitting shown in FIG. 5B is performed. As shown in FIG. 5B, portions a, b, and c in which adjacent wales are not connected by the jacquard yarn are generated in this structure. These portions a, b, and c become the through holes 41 in the warp knitted fabric 30. The size of the through hole 41 and the place where it is formed can be changed depending on the course of displacing the jacquard guide and the way of selecting the direction of displacement. Although only a part of the jacquard yarns 50 to 53 are shown in FIGS. 5B and 6, the jacquard yarns that move in the same manner as the illustrated jacquard yarns 50 to 53 are unfolded to the left and right. The

  Further, an elastic yarn guided by the ground 15 may be inserted into the net portion 40 in the warp direction. Further, the net portion 40 may be knitted with a pattern yarn introduced from the handle rod 14 to form a pattern with the pattern yarn. However, it is desirable that the pattern yarn is separated from the cutting yarn 54 described below by 2 wales or more.

  As shown in FIG. 4, a cut yarn 54 is knitted in a portion on the side of the discarding portion 32 from the boundary 34 between the product portion 31 and the discarding portion 32 so as to draw a scalloped shape. This means that there is a boundary 34 between the product portion 31 and the discard portion 32 at a position closer to the product portion 31 than the knitted portion 37 of the cutting yarn 54. It is desirable that the knitted portion 37 and the boundary 34 of the cutting yarn 54 are adjacent to each other.

  The cocoon for introducing the cutting yarn 54 is, for example, one of the plurality of handle ridges 14. The cutting yarn 54 is desirably knitted by insertion, but may be knitted by forming a stitch. Further, the cutting yarn 54 may be knitted by a so-called fall plate wrap in which a part of the stitches is removed with a falling plate while being moved so as to form a stitch.

  An example of a method for inserting the cutting thread 54 is shown in FIG. In FIG. 7, the cutting thread 54 is drawn with a solid line. In the description of FIG. 7, the width direction is the width direction of the product portion 31, and the recess and the protrusion are the scalloped recess and protrusion of the product portion 31. The convex portion is on the disposal portion 32 side, and the concave portion is on the product portion 31 side.

  In this example, the cutting yarn 54 is first inserted in a zigzag manner over a plurality of courses at the wale w1 which is the apex 44 of the first recess. Next, one cutting yarn 54 is transferred to the wale w2 on the discard part 32 side, and inserted in a zigzag manner over the plurality of courses in the wale w2. In this manner, after the cutting yarn 54 is inserted into a zigzag over a plurality of courses in one wale, one is repeatedly transferred to the wale on the discarding portion 32 side. When the cutting yarn 54 is inserted into the wale w5 that is the apex 45 of the convex portion in a zigzag manner, this time, one is passed to the wale w4 on the product portion 31 side and inserted into the zigzag over a plurality of courses in the wale w4. . In this manner, after the cutting yarn 54 is inserted in a zigzag over a plurality of courses in one wale, one cut is repeatedly given to the wale on the product part 31 side. And in the wale w1 of the place used as the vertex 44 of the 2nd recessed part, it inserts in a zigzag over several courses. By repeating the above insertion over many courses, the cutting thread 54 is inserted into a scalloped shape.

  In the warp knitted fabric 30, the knitted portion 37 of the cutting yarn 54 protrudes to the surface of the warp knitted fabric 30 more than the portion on the product portion 31 side. Therefore, the braided portion 37 of the cutting yarn 54 is thicker than the portion on the product portion 31 side.

  In order to project the knitted portion 37 of the cutting yarn 54 to the surface of the warp knitted fabric 30, the cutting yarn 54 is somewhat thick. The cutting yarn 54 is desirably thicker than the jacquard yarns 50 to 53, and more preferably 600 dtex or more. Incidentally, the jacquard yarns 50 to 53 are, for example, 30 to 55 dtex.

  In addition to the cutting yarn 54, it is desirable to knit the heat-sealing yarn 55 into at least a part of the net portion 40. The heat-fusible yarn 55 is a yarn that melts at least a part when heated at a predetermined temperature for a predetermined time and bonds the other two or more yarns together. Such adhesion is called heat fusion. The heat-sealing yarn 55 used in the present embodiment may be anything that is heat-sealed by heat setting in the dyeing process. Examples of the heat-sealing yarn 55 include a low-melting-point nylon yarn that is heat-sealed at 100 to 130 ° C.

  The place where the thermal fusing yarn 55 is knitted is at least a wale y (see FIG. 7) adjacent to the reference wale x on the product part 31 side from the wale (reference wale x) where the cutting yarn 54 is knitted. is there. The place where the heat-fusible yarn 55 is knitted may include at least the wale y and may be only the wale y, but may be a plurality of continuous wales closer to the product portion 31 than the reference wale x. More desirable. Further, in addition to the wales on the product part 31 side from the reference wal x, the heat fusion yarn 55 may be knitted into the reference wal x.

  An example of a method for inserting the heat-sealing yarn 55 is shown in FIG. In FIG. 7, the heat fusion yarn 55 is drawn with a broken line. In this example, five heat-sealing yarns 55 are inserted. In any course, the thermal fusion yarn 55 is inserted in a zigzag manner at least in the reference wal x, the wal y one next to the reference wal x, and the wal z adjacent to the wal.

  As for the method of weaving the heat-fusible yarn 55, as shown in FIG. 7, weaving by insertion is desirable, but a method of weaving to form a stitch may be used. The heat fusion yarn 55 is introduced by, for example, the handle 11.

  The main portion 42 of the product portion 31 (see FIG. 4), that is, the portion on the inner side in the width direction from the net portion 40 can be various laces. The lace fabric is a knitted fabric in which a pattern is formed by the arrangement of the plurality of through holes 41, the shape of each through hole, the density of yarns, and the like. As shown in FIG. 4, the main part 42 may also have a net shape. Even if the main part 42 has a net shape, the main part 42 and the net part 40 have different knitting structures. In the case of using the warp knitting machine having the knitting portion of FIG. 1, for example, a ground yarn that forms a ground structure is guided by the ground rod 10, and a patterned yarn that draws a pattern by the handle rod 14 is guided. The part 42 is knitted as a race place. When the warp knitting machine is equipped with the jacquard scissors 12, 13, by further shifting the jacquard guide in the left-right direction while guiding the jacquard yarn with the jacquard scissors 12, 13 that perform a certain movement A hole portion, a thick portion, and a thin portion can be formed in the main portion 42, and a pattern formed by these portions can be formed.

  The organization of the discard unit 32 is not limited. As shown in FIG. 4, the organization may be different from the net unit 40, but may be the same organization as the net unit 40.

  In the dyeing process of the present embodiment, the warp knitted fabric 30 knitted as described above is dyed and heat set after dyeing. The heat setting temperature at the time of heat setting and the holding time at the temperature may be any temperature and time at which the heat-fusible yarn 55 is heat-sealed. For example, the heat set temperature is 180 to 190 ° C., and the holding time at the heat set temperature is 30 to 90 seconds. By heat setting, the shape of the through hole 41 is stabilized in the net part 40 or the like of the warp knitted fabric 30, and as a result, the handle made of the through hole 41 or the like is stabilized. Further, in the portion where the heat fusion yarn 55 is knitted, the heat fusion yarn 55 is melted and the yarns other than the heat fusion yarn 55 are thermally fused. After heat fusion, the heat fusion yarn 55 itself may not keep the shape as a yarn, or may keep the shape as a yarn. The shape of the through hole 41 of the net part 40 is fixed by heat sealing.

  In the cutting process of the present embodiment, the warp knitted fabric 30 is cut along the knitting portion 37 of the cutting yarn 54 at the boundary 34 between the product portion 31 and the discarding portion 32, and the discarding portion 32 including the cutting yarn 54 is removed. To do. Since the boundary 34 extends in the wale direction, the cutting direction is the wale direction. As a preferable cutting method, a method is adopted in which a cutter is applied to the boundary 34 between the product portion 31 and the discarding portion 32 and the warp knitted fabric 30 is directed to the cutter in this state. In this preferable cutting method, since the warp knitted fabric 30 and the cutter may be relatively moved so that the warp knitted fabric 30 faces the cutter, if at least one of the warp knitted fabric 30 or the cutter is moved, good. That is, only the warp knitted fabric 30 may be moved without moving the cutter, or only the cutter may be moved without moving the warp knitted fabric 30, or both the cutter and the warp knitted fabric 30 may be moved. You may let them. The cutter may be anything as long as it can cut the warp knitted fabric 30.

  The further preferable example of said preferable cutting method is shown. First, as shown in FIGS. 8 to 10, the cutting device used in the cutting process includes a cutter 60 that is a rotating circular blade. A guide 62 having a gap 61 is provided in front of the cutter 60. The guide 62 may be anything as long as it has a gap 61. The gap 61 opens to the front, rear, left and right. In the description of the cutting device and the cutting process, front and rear are expressions when the gap 61 is the front and the cutter 60 is the rear, and left and right are expressions when the rear is viewed from the front.

  The guide 62 in the embodiment of FIGS. 8 to 10 is composed of a pair of upper and lower bar-shaped or plate-shaped members, and a gap 61 is formed between the pair of upper and lower members. The size of the gap 61 is set to such a size that the portion of the warp knitted fabric 30 that is closer to the product portion 31 than the knitted portion 37 of the cutting yarn 54 can pass but the knitted portion 37 of the cutting yarn 54 cannot pass. . In the case of the present embodiment, it is desirable that the cutter 60 be in a position behind the opening end 63 on the right side of the guide 62 as shown in FIG.

  When cutting using this cutting device, the cutter 60 is first rotated, and then the warp knitted fabric 30 after heat setting is sent out from the front side to the back side of the guide 62. At that time, the product part 31 of the warp knitted fabric 30 is on the left side and the discard part 32 is on the right side. The arrow M in FIGS. 8-10 is the advancing direction of the warp knitted fabric 30. FIG. Since the guide 62 is in front of the cutter 60, the warp knitted fabric 30 is directed toward the rear cutter 60 while passing a part of the warp knitted fabric 30 through the gap 61 of the guide 62.

  As shown in FIGS. 8, 9, and 11, when the warp knitted fabric 30 is passed through the gap 61 of the guide 62, the knitted portion 37 of the cutting yarn 54 is placed on the right side of the gap 61 of the guide 62 (that is, the discarding portion 32 side). ) Is passed through the gap 61 of the guide 62 from the knitting portion 37 of the cutting yarn 54 to the left side (that is, the product portion 31 side). Thereby, the positional relationship in the left-right direction between the warp knitted fabric 30 and the cutter 60 is determined, and the warp knitted fabric 30 is directed toward the cutter 60. When the warp knitted fabric 30 reaches the cutter 60, the cutter 60 hits the position on the product portion 31 side from the knitting portion 37 of the cutting yarn 54 (the boundary 34 between the product portion 31 and the discarding portion 32 is at this position) The warp knitted fabric 30 is cut along the knitted portion 37 of the cutting yarn 54.

  When the warp knitted fabric 30 is sent out, the product portion 31 may be on the right side and the discarding portion 32 may be on the left side in the opposite directions to those in FIGS. 8, 9, and 11. In that case, when the warp knitted fabric 30 is passed through the gap 61 of the guide 62, the knitted portion 37 of the cutting yarn 54 is cut against the opening end to the left side of the gap 61 of the guide 62 (that is, the discarding portion 32 side). A portion on the right side (that is, the product portion 31 side) of the knitted portion 37 of the yarn 54 may be passed through the gap 61 of the guide 62. In this case, it is desirable that the cutter 60 be in a position behind the opening end on the left side of the gap 61.

  The product part 31 and the discard part 32 that have been cut and separated as described above are each wound up by a winding device (not shown) in the traveling direction after the cutting. Thus, the product part 31 after removing the discard part 32 is the lace fabric 33 used as a product.

  As shown in FIG. 12, the knitted lace fabric 33 after the cutting step has a net portion 40 having a constant width including its widthwise end. And the edge part 43 of the width direction is in the state which cut | disconnected the net part 40. FIG. Therefore, at the end portion 43 in the width direction of the knitted lace fabric 33, the end portions where the yarn constituting the net portion 40 is cut are lined up with an interval equivalent to the size of the through hole 41 of the net portion 40. . Furthermore, the end 43 in the width direction of the knitted lace fabric 33 has a scalloped shape. When the heat fusion yarn 55 is knitted into the net portion 40 as described above, the yarns are bonded to each other at the end portion 43 in the width direction of the lace knitted fabric 33.

  Note that the net portion 40 of FIG. 12 has a substantially uniform net shape throughout. That is, the net part 40 in FIG. 12 is composed of the same knitting structure throughout and has no pattern formed thereon. However, the net part 40 does not have to have such a net shape, for example, the net shape may be partially changed to form a pattern only with the net, or as described in the knitting process, A pattern may be formed by knitting a pattern yarn.

  The knitted lace fabric 33 is attached by means such as sewing as a part of underwear such as shorts and brassiere, outerwear, and other various clothing.

  The effect of this embodiment is as follows. First, according to the method for manufacturing the knitted lace fabric 33 of the present embodiment, the novel design characteristics in which the end portion 43 in the width direction of the lace knitted fabric 33 is in a scalloped shape and the net portion 40 remains cut. Can be at the end with Moreover, the knitted lace fabric 33 having such end portions 43 can be easily obtained simply by cutting the warp knitted fabric 30 along the knitted portion 37 of the cutting yarn 54.

  In particular, in this embodiment, since the warp knitted fabric 30 is moved by moving it with respect to the cutter 60 in a state where the cutter 60 is applied to the position closer to the product portion 31 than the knitting portion 37 of the cutting yarn 54, it is easily cut. The warp knitted fabric 30 can be cut along the yarn 54.

  Further, in the present embodiment, by passing a part of the warp knitted fabric 30 through the gap 61 of the guide 62 while applying the knitted portion 37 of the cutting yarn 54 of the warp knitted fabric 30 to the opening end 63 of the gap 61 of the guide 62, In order to determine the positional relationship between the cutter 60 behind the gap 61 and the warp knitted fabric 30 in the left-right direction, the cutter 60 can be reliably and easily applied to the position closer to the product portion 31 than the braided portion 37 of the cutting yarn 54. Therefore, the warp knitted fabric 30 can be cut reliably and easily along the knitted portion 37 of the cutting yarn 54.

  In the present embodiment, in the knitting process, at least the wales on the product part 31 side of the wales where the cutting yarns 54 are knitted and adjacent to the wales where the cutting yarns 54 are knitted are heated. The fusion yarn 55 is knitted and heat-sealed by heat setting. For this reason, even if the portion on the product portion 31 side is cut from the braided portion 37 of the cutting yarn 54 after heat setting, the end portion on the product portion 31 side, that is, the end portion 43 in the width direction of the lace knitted fabric 33 is unlikely to fray. .

  Further, when the heat-fusible yarn 55 is knitted by insertion, the amount of the heat-fusible yarn 55 used is smaller than when the knitted yarn is knitted by forming a stitch. Therefore, the portion where the heat-sealing yarn 55 is knitted is not easily hardened, and the cost is not increased.

  Moreover, the end part of the width direction of the product part 31 is a scallop shape which has the curved part 35 like the wave shape shown to Fig.3 (a), or the shape which the arc shown to FIG.3 (b) continues in a wale direction. If there is, even if the cutting speed is increased, the cutting can be performed along the cutting yarn 54 without any delay. In particular, if the end portion in the width direction of the product portion 31 is corrugated, there is no corner portion in the traveling direction of the cutter 60, so that even if the cutting speed is considerably increased, cutting can be performed along the cutting yarn 54 without any delay.

  Further, if the net portion 40 is knitted so as to have a uniform net shape throughout, it is easy to cut in the cutting step, and the vicinity of the end 43 of the knitted lace fabric 33 looks more novel.

  The above embodiment is an illustration and the scope of the invention is not limited to this. Various changes, substitutions, omissions, and the like can be made to the above embodiments without departing from the scope of the invention.

  First, in the cutting process of the above embodiment, the cutter 60 was applied in parallel to the wale direction of the warp knitted fabric 30 as shown in FIG. You can also tilt it. When the cutter 60 is tilted with respect to the wale direction of the warp knitted fabric 30, the cutter 60 is tilted so that the cutting edge of the cutter 60 faces the cutting yarn 54. The angle θ formed by the cutter 60 and the wale direction of the warp knitted fabric 30 is not limited. However, as a desirable mode, the angle θ is 45 degrees or less. By tilting the cutter 60 in this way, the warp knitted fabric 30 can be cut cleanly along the knitted portion 37 of the cutting yarn 54.

  Moreover, in the preferable form of the said embodiment, although a net | network shape is fixed by heat-sealing yarns in a part of net | network part 40, yarns are adhere | attached by methods other than heat-fusion, thereby The net shape may be fixed.

  Moreover, the manufacturing method of the said embodiment can be used for manufacture of the lace fabric by which a part of edge part of the width direction is a scallop shape. That is, in the manufacturing method of the above embodiment, not only the lace knitted fabric in which the entire end portions on both sides in the width direction are scalloped shape, but also the entire end portion on one side in the width direction is scalloped shape and the end on the other side in the width direction. Part is a lace knitted fabric that is not scalloped, a lace knitted fabric in which only a part of both ends in the width direction is scalloped, a lace knitted fabric in which only a part of the end on one side in the width direction is scalloped, etc. Can also be used in the manufacture of

  Further, as described above, the organization of the net unit 40 is not limited to that of the above embodiment. For example, instead of forming a single yarn with a single wal, only one knitting yarn is formed with multiple courses continuously with one wal and then transferred to the next wal. It is also possible to repeat the process of forming the stitches for a plurality of courses in succession and then returning to the original wal. Also in this case, a through hole having an arbitrary size can be formed depending on the method of inserting the jacquard yarn.

  Moreover, the method of the said embodiment can be used also for manufacture of the lace fabric by which the edge part of the width direction is not a scallop shape, for example, the edge part of the width direction is linear. When manufacturing a knitted lace fabric having a straight end in the width direction, in the knitting of the warp knitted fabric, a portion closer to the product portion than the boundary between the product portion and the discarded portion (in this case, the boundary is linear) Is cut into a net shape, and a yarn for cutting is knitted in a straight line into a portion on the side of the discarded portion adjacent to the boundary between the product portion and the discarded portion. Then, after knitting, the warp knitted fabric is cut along the knitted portion of the cutting yarn by the same method as in the above embodiment, and the discarded portion including the knitting portion of the cutting yarn is removed. Then, the edge part of the width direction of a lace knitted fabric can be made into the edge part which has the novel design property of the state which is linear and the net part has been cut.
