Description

Technical Field

[0001] This invention relates to a warp knitting machine and a method for knitting warp-knitted fabrics. Background Technology

[0002] As described in Patent Document 1, warp knitting machines with one knitting needle row, multiple guide combs and one folding plate are known.

[0003] In this warp knitting machine, the yarn supplied from the guide comb positioned behind the pleats is hung on the knitting needles to form a base structure consisting of needle arcs and sinker arcs, just as in the case of a warp knitting machine without pleats.

[0004] On the other hand, the yarn supplied from the guide bar, which is positioned behind the folding plate, is temporarily hung on the knitting needle, but is pushed downwards by the folding plate relative to the needle hook. The pushed-down yarn does not form a needle arc at the needle arc position of the base structure, but is only knitted into the sinker arc of the base structure. When using the folding plate, this yarn produces a unique knit structure in the warp-knitted fabric.

[0005] Patent Document 1: Japanese Patent Application Publication No. 10-168719 Summary of the Invention

[0006] However, in the warp knitting machine described in Patent Document 1, since each guide bar only performs a predetermined movement repeatedly, no pattern variation due to different parts is produced. To produce pattern variation due to different parts, it is possible to consider changing some of the guide bars to jacquard guide bars. However, if the guide bars of a conventional warp knitting machine are changed to jacquard guide bars, warp-knitted fabrics cannot be knitted smoothly.

[0007] Therefore, the present invention aims to provide a warp knitting machine capable of smoothly knitting warp-knitted fabrics with patterns varying depending on the location of the warp. Furthermore, the present invention aims to provide a method for smoothly knitting warp-knitted fabrics with patterns varying depending on the location of the warp.

[0033] The warp knitting machine of this embodiment includes a knitting section consisting of knitting needle rows, multiple guide combs, grid plates, and needle combs. In the knitting section, warp-knitted fabrics are woven from various yarns. Furthermore, the warp knitting machine of this embodiment includes a supply section for feeding yarn to the knitting section, a take-up device for winding the warp-knitted fabric woven by the knitting section, and a fiber dust prevention device for drawing excess fibers from the warp-knitted fabric woven by the knitting section.

[0034] The arrangement of the guide bars in the warp knitting machine of this embodiment is as follows: Figure 1 As it is. Figure 1 The direction perpendicular to the paper surface is the width direction of the warp knitting machine (as the width direction of the weaving machine). Additionally, Figure 1 The left and right directions correspond to the front and back directions of the warp knitting machine. In Figure 1 In the center, left is front and right is back.

[0035] The warp knitting machine of this embodiment is a single Raschel warp knitting machine with one knitting needle row. The knitting needle row consists of multiple knitting needles 10. The knitting needle 10 of this embodiment is a compound needle. The compound needle has a known structure with a hook 11. This hook is opened and closed by a known latch (not shown). However, a known latch needle may be used instead of a compound needle.

[0036] In addition, the warp knitting machine of this embodiment includes a folding plate FP, two half-spaced jacquard guide bars JB1 and JB2 arranged in front of the folding plate FP, and three bottom guide guide bars GB3, GB4 and GB5 arranged in the rear of the folding plate FP.

[0037] exist Figure 2 In simplified representation, this indicates the configuration of the yarn guides on each individual yarn guide bar. Figure 2 In the diagram, the top part represents the front of the warp knitting machine, and the bottom part represents the rear. The lines in the diagram represent yarn guides, and the circles represent knitting needles 10. Actual warp knitting machines have... Figure 2 More than 10 knitting needles and yarn guides. Figure 2 , the folding plate FP is omitted.

[0038] In each of the three bottom guide bars GB3, GB4, and GB5, multiple yarn guides are arranged side-by-side in the width direction of the knitting machine. The three bottom guide bars GB3, GB4, and GB5 are all full-spaced guide bars. That is, in each of the bottom guide bars GB3, GB4, and GB5, the number of yarn guides per inch is the same as the number of knitting needles 10 per inch, and each yarn guide is positioned corresponding to each knitting needle 10.

[0039] Bottom guide combs GB3, GB4, and GB5 perform basic knitting movements for the fabric structure. Multiple yarn guides mounted on a single bottom guide comb perform the same movements. At least one of the bottom guide combs GB3, GB4, and GB5 is a base fabric with a lockknit structure that forms multiple loops in the warp and weft directions.

[0040] Furthermore, in each of the two semi-spaced jacquard guide bars JB1 and JB2, multiple jacquard yarn guides are arranged side by side in the width direction of the knitting machine. The semi-spaced jacquard guide bars JB1 and JB2 are respectively semi-spaced jacquard guide bars. Here, the number of jacquard yarn guides per inch is half the number of knitting needles 10 per inch. A jacquard guide bar with jacquard yarn guides configured at a ratio of one jacquard yarn guide to two knitting needles 10 is called a "semi-spaced jacquard guide bar".

[0041] In each of the two half-spaced jacquard guide bars JB1 and JB2, one jacquard yarn guide is provided relative to the two knitting needles 10. Moreover, if the two half-spaced jacquard guide bars JB1 and JB2 are combined, the number of knitting needles 10 is the same as the number of jacquard yarn guides.

[0042] The jacquard yarn guides of the half-spaced jacquard guide bar JB1 and the half-spaced jacquard guide bar JB2 are staggered only by the same interval as the knitting needles 10. If two half-spaced jacquard guide bars JB1 and JB2 are added together, then one jacquard yarn guide is configured relative to one knitting needle 10, and the same number of jacquard yarn guides as knitting needles 10 are arranged side by side at equal intervals in the width direction of the knitting machine.

[0043] The semi-spaced jacquard guide bars JB1 and JB2 perform basic movements for weaving the basic structure. Simultaneously, multiple jacquard yarn guides, each mounted on the semi-spaced jacquard guide bars JB1 and JB2, perform basic movements for weaving the basic structure.

[0044] Based on the fundamental movements used for weaving the basic structure, these jacquard yarn guides can be independently displaced by the action of the jacquard mechanism. Therefore, multiple jacquard yarn guides can each perform different movements. When the jacquard mechanism is activated, the jacquard yarn guides are displaced only a distance of 1G (the interval between two adjacent knitting needles 10) in the width direction of the knitting machine compared to their position in the weaving of the basic structure. The jacquard mechanism can function either only during overlap, only during needle backing, or both during overlap and needle backing.

[0045] Through the action of the jacquard mechanism, the jacquard yarn, supplied from the semi-spaced jacquard combs JB1 and JB2, is incorporated into the base structure in different forms according to the location of the warp-knitted fabric. The weaving structure formed by the jacquard yarn is called jacquard structure.

[0046] exist Figure 1 In the arrangement, from the half-spaced jacquard comb JB1 to the bottom yarn guide comb GB4, it can overlap with the knitting needle 10.

[0047] The folding plate FP has one steel plate. The folding plate FP can move up and down and descend in front of the knitting needle 10.

[0048] Here, the role of the folded plate FP is based on Figures 3-5 Please provide an explanation. Furthermore, in Figure 3 For simplicity, only a portion of the yarn guide is shown in the image. Additionally, in... Figure 3 In the diagram, for reference, the latch needle is shown as knitting needle 10 instead of a compound needle, but the type of latch needle used does not affect the following instructions. Additionally, in Figure 4 and Figure 5 For simplicity, only a portion of the yarn is shown in the drawing.

[0049] The folding plate FP functions relative to the jacquard yarn supplied from the semi-gap jacquard guide bars JB1 and JB2. Specifically, the jacquard yarn guides of the semi-gap jacquard guide bars JB1 and JB2 oscillate inward, overlap, and oscillate outward relative to the knitting needles 10. During this series of movements, as... Figure 3 (a) After the jacquard yarn guide 13 hangs the jacquard yarn 14 on the knitting needle 10 by overlapping, as in (a) Figure 3 As in (b), the folding plate FP descends, pushing the jacquard yarn 14 down. As it is pushed down, the jacquard yarn 14 descends downwards relative to the portion of the hook 11 of the knitting needle 10.

[0050] The unique folded-plate hanging thread structure is formed by the action of such folded plates FP. The folded-plate hanging thread structure is a weaving structure in which the jacquard yarn 14 is woven into the sinker arc of the base structure without forming a needle arc at the needle arc position of the base structure.

[0051] For example, Figure 4 and Figure 5 It is a diagram of jacquard yarn 14 when the base structure is a lockknit structure with open loops. Figure 4 This is a diagram illustrating the movement of the warp flat weave, where the half-spaced jacquard combs JB1 and JB2 are used to weave closed loops, as shown in (a). Additionally, Figure 5 This is a diagram illustrating the movement of the warp flat weave with open loops using the semi-spaced jacquard combs JB1 and JB2, as shown in (a). In either case, from Figure 4 (b) and Figure 5 (b) It can be seen that the jacquard yarn 14 (the thicker yarn in the figure) supplied from the half-gap jacquard combs JB1 and JB2 is not knitted into the sinking arc 16 of the base structure at the position of the needle knitting arc 15 of the base structure.

[0052] Furthermore, in the insert weave, there is no situation where a single yarn (insertion yarn) crosses; in contrast, in the pleated suspension weave, there is... Figure 4 (b) and Figure 5 (b) It can be seen that at the loop position, one jacquard yarn 14 crosses. In this respect, the pleated hanging yarn structure differs from the insert structure.

[0053] In this way, the warp knitting machine, by having a folded plate (FP), can perform knitting using the folded plate FP, and can knit a unique folded plate hanging thread structure.

[0054] Furthermore, the warp knitting machine of this embodiment, in order to supply yarn to the three bottom guide guide bars GB3, GB4, and GB5, includes multiple warp beams, three warp beam cores, and three feed devices (none of which are shown). The warp beams, warp beam cores, and feed devices are part of the supply unit. Multiple warp beams, one warp beam core, and one feed device are provided relative to one bottom guide guide bar.

[0055] Multiple warp beams carrying yarn are connected to a single warp beam core. Furthermore, yarn is supplied from these warp beams to multiple yarn guides within a single bottom guide bar. The amount of yarn fed is adjusted by a feeding device. Therefore, the yarn feed is adjusted for each bottom guide bar. That is, yarn is supplied to all the yarn guides within the single bottom guide bar with the same feed rate.

[0056] In addition, to supply jacquard yarn to the two semi-spaced jacquard guide bars JB1 and JB2, a warp frame (not shown) is installed on the warp knitting machine as another part of the supply section. Multiple yarn packages are mounted on the warp frame. Yarn packages are structures formed by winding raw yarn into shapes such as cheese, cones, or bread.

[0057] Jacquard yarns are fed one by one from their respective yarn packages to their respective jacquard guides. Furthermore, tension is applied independently to each yarn pulled from its respective yarn package. Therefore, the amount of jacquard yarn fed from the warp frame to the two half-spaced jacquard guide bars JB1 and JB2 can be adjusted one yarn at a time.

[0058] Multiple yarn packages on the warp frame and multiple jacquard guides on the front half-spaced jacquard guide bar JB1 form multiple yarn paths for supplying jacquard yarn (referred to as "front jacquard yarn paths"). Additionally, multiple other yarn packages on the warp frame and multiple jacquard guides on the rear half-spaced jacquard guide bar JB2 form multiple yarn paths for supplying jacquard yarn (referred to as "rear jacquard yarn paths"). The front and rear jacquard yarn paths are separated front and rear.

[0059] The front jacquard yarn channel is a channel that supplies jacquard yarn from the front compared to the front half-pitch jacquard carding bar JB1. More precisely, "supplying jacquard yarn from the front compared to the front half-pitch jacquard carding bar JB1" means supplying jacquard yarn from the front compared to the guide holes formed on the jacquard yarn guide of the front half-pitch jacquard carding bar JB1.

[0060] Furthermore, the rear jacquard yarn path is the channel through which the aforementioned rearward-facing half-pitch jacquard guide bar JB2 supplies jacquard yarn from the rear compared to the rearward-facing half-pitch jacquard guide bar JB2. More precisely, "supplying jacquard yarn from the rear compared to the rearward-facing half-pitch jacquard guide bar JB2" means supplying jacquard yarn from the rear compared to the guide holes formed on the jacquard yarn guide of the rearward-facing half-pitch jacquard guide bar JB2.

[0061] The semi-spaced jacquard combs JB1 and JB2 move forward and backward by inward and outward swinging motions, but even if they move like that, the supply direction of the front jacquard yarn path and the rear jacquard yarn path remains unchanged.

[0062] The warp knitting machine of this embodiment also includes a take-up device (not shown) for taking up the warp-knitted fabric. The take-up device has a known structure with multiple take-up rollers. Furthermore, a take-up path for the warp-knitted fabric is formed from the knitting section, including the knitting needles 10, to the take-up device.

[0063] A fiber dust prevention device is installed relative to this winding path. For example... Figure 6As shown, the fiber dust prevention device includes an air supply device 21 that supplies air to one side (e.g., the inner side) of the warp-knitted fabric 1 passing through the take-up path; and an attraction device 22 that draws air from the other side (e.g., the outer side) of the warp-knitted fabric 1 passing through the take-up path. Although not shown in the figure, the fiber dust prevention device includes multiple air supply devices 21 and multiple attraction devices 22. The multiple air supply devices 21 and multiple attraction devices 22 are arranged side by side in the width direction of the knitting machine. Each air supply device 21 and each attraction device 22 is arranged facing each other with a gap between them on the warp-knitted fabric.

[0064] As the warp-knitted fabric 1 passes through the take-up path, air is supplied from the air supply device 21 and suction is performed by the suction device 22 in parallel. By allowing air to pass through the warp-knitted fabric 1, excess fibers can be attracted by the suction device 22.

[0065] The movement of the knitting needles 10, pleats FP, semi-spaced jacquard guide bars JB1, JB2, and bottom guide guide bars GB3, GB4, GB5, etc., is controlled by a control unit (not shown) on the warp knitting machine.

[0066] The warp knitting machine of this embodiment also has the same structure as the well-known single Raschel warp knitting machine.

[0067] Next, the method of warp knitting fabrics made by the warp knitting machine constructed as described above and the warp knitted fabrics will be explained.

[0068] Before weaving, some or all of the three bottom guide combs GB3, GB4, and GB5 are selected as the bottom guide combs to be used in the weaving process. Moreover, during weaving, the yarn is supplied from all the yarn guides of the axially selected bottom guide comb.

[0069] In addition, during weaving, jacquard yarn is supplied from the warp frame to the respective jacquard guides of the two semi-spaced jacquard guide bars JB1 and JB2. Specifically, jacquard yarn is supplied one by one to all the jacquard guides of the front semi-spaced jacquard guide bar JB1 through the front jacquard yarn path. Similarly, jacquard yarn is supplied one by one to all the jacquard guides of the rear semi-spaced jacquard guide bar JB2 through the rear jacquard yarn path. The amount of jacquard yarn fed out is adjusted for each individual jacquard yarn.

[0070] The fineness of the yarn supplied to the bottom guide combs GB3, GB4, and GB5 is not limited, but may be, for example, 600 dtex or less. Additionally, the jacquard yarn supplied to the semi-gap jacquard combs JB1 and JB2 is not limited, but may be coarser than the yarn supplied to the bottom guide combs GB3, GB4, and GB5. The fineness of the jacquard yarn supplied to the semi-gap jacquard combs JB1 and JB2 is, for example, 600 dtex or more and 1200 dtex or less.

[0071] Furthermore, there are no restrictions on the type of yarn used. Both staple fiber yarn and staple fiber yarn can be used. Additionally, both natural fiber yarn and synthetic fiber yarn can be used.

[0072] In the weaving process, the base structure is woven using selected bottom guide bars. Parallel to the base structure weaving, the jacquard structure is woven using two semi-spaced jacquard guide bars JB1 and JB2. The jacquard mechanisms of the semi-spaced jacquard guide bars JB1 and JB2 function differently depending on the location, resulting in different weave structures formed by the jacquard yarns according to the location.

[0073] When the bottom guide bar and the half-spaced jacquard guide bars JB1 and JB2 overlap at the same loop position, control is performed in a manner where the overlap direction of the bottom guide bar and the overlap direction of the half-spaced jacquard guide bars JB1 and JB2 are opposite. Furthermore, for all loop positions where both the bottom guide bar and the half-spaced jacquard guide bars JB1 and JB2 overlap, control is performed in a manner where the overlap direction of the bottom guide bar and the overlap direction of the half-spaced jacquard guide bars JB1 and JB2 are opposite. Additionally, loop position refers to the position of the loops in the base structure woven by the bottom guide bar.

[0074] In the knitting of a jacquard structure, the pleated plate FP acts on the jacquard yarn suspended on the knitting needles 10 by the semi-spaced jacquard guide bars JB1 and JB2. Each time the jacquard yarn guide overlaps, the pleated plate FP pushes the jacquard yarn off the hooks 11 in the knitting needles 10. This forms a pleated suspended yarn structure.

[0075] Furthermore, in at least a portion of the warp-knitted fabric, between two loop positions where the jacquard yarn is knitted into the sinker arc of the base fabric, the jacquard yarn forms a structure that floats towards the front of the warp-knitted fabric. To illustrate this, in Figure 7 This is represented in (a) and (b). Figure 7 In (a) and (b), the dashed lines represent the basic structure formed by the half-spaced jacquard combs JB1 and JB2, and the solid lines represent the weaving structure when the basic structure changes due to the action of the jacquard mechanism.

[0076] like Figure 7 As shown in (a), the jacquard mechanism creates a position where the semi-spaced jacquard guide bars JB1 and JB2 do not overlap, forming a backing yarn position. This position is indicated by the arrow in the diagram. At this position, the jacquard yarn rises towards the front of the warp-knitted fabric without being knitted into the sinker arc of the base fabric. The risen jacquard yarn, as indicated by the double-dotted line in the diagram, extends in the warp direction between the two loop positions knitted into the sinker arc of the base fabric.

[0077] In addition, such as Figure 7As shown in (b), the jacquard mechanism creates positions where the half-spaced jacquard combs JB1 and JB2 are used for backing yarn placement across two loops in the warp. In this case, between the two loop positions where the jacquard yarn is knitted into the sinker arc of the base yarn, the jacquard yarn floats towards the front of the warp-knitted fabric without being knitted into the sinker arc of the base structure. The range of this floating is indicated by wavy brackets in the figure.

[0078] Through such weaving by bottom guide combs and semi-spaced jacquard combs JB1 and JB2, the jacquard yarn is woven into the sinking arc of the base structure without forming a needle arc at the needle arc position, and in a part of the warp-knitted fabric, the jacquard yarn is woven into a warp-knitted fabric in which the jacquard yarn floats between two loop positions.

[0079] In this weaving process, the fiber dust prevention device operates, and the suction device 22 attracts the airborne fibers. When short fiber yarns are used in warp-knitted fabrics, many short fibers fly off during weaving, but the suction device 22 attracts them. The warp-knitted fabric that has passed through the section containing the fiber dust prevention device is then wound up by the take-up device.

[0080] Compared to the warp-knitted fabrics described above, these undergo final processing such as heat setting. Then, the warp-knitted fabrics are cut and sewn into garments, etc.

[0081] Next, use Figures 8 to 16 This section provides more detailed examples of weaving methods and warp-knitted fabrics. Figures 8-11 This is an example of two half-spaced jacquard combs, JB1 and JB2, woven with the same basic weave. Additionally, Figures 12-16 This is an example of a case where the basic weave of two half-spaced jacquard combs JB1 and JB2 is a counter-wrapping weave.

[0082] First of all, Figures 8-11 The following example will be used to illustrate this.

[0083] exist Figure 8 The text indicates the weaving structure formed by the bottom guide combs GB3, GB4, and GB5. Additionally, in... Figure 8 The term "basic structure" also indicates the basic weave structure formed by the semi-spaced jacquard guide bars JB1 and JB2. The basic structure refers to the weave structure when the jacquard mechanism is not in operation.

[0084] Bottom guide bar GB3 and bottom guide bar GB4 are used to weave the base structure. Bottom guide bar GB3 is woven with a lockknit structure. If this lockknit structure is represented by a chain number, it is 0-1 / 1-0 / / . Additionally, bottom guide bar GB4 is woven with a warp knit structure. If this warp knit structure is represented by a chain number, it is 1-2 / 1-0 / / . Thus, by combining lockknit and warp knit structures in the base structure, the warp-knitted fabric becomes thicker. Furthermore, the loops of the lockknit and warp knit structures overlap, each loop forming two layers, making the yarns more difficult to unravel.

[0085] exist Figure 8 The arrows indicate the overlapping direction of the bottom guide combs GB3 and GB4. The arrows also show that the lockknit and warp knit overlap in the same direction.

[0086] Additionally, the bottom guide bar GB5 incorporates an insert structure. If this insert structure is represented by a chain number, it is 0-0 / 1-1 / 0-0 / 3-3 / 2-2 / 3-3 / / . The chain number also indicates that the insert yarn forming this structure extends not only in the warp direction but also in the weft direction, inserting itself along the three wale loops. By supplying non-stretch yarn to the bottom guide bar GB5 and inserting this non-stretch yarn in this way, the warp-knitted fabric becomes less prone to stretching in either the warp or weft direction.

[0087] In addition, the two half-spaced jacquard combs JB1 and JB2 are woven with the same basic structure. The basic structure of the half-spaced jacquard combs JB1 and JB2 is a plain warp weave. If this plain warp weave is represented by chain numbering, it is 1-0 / 1-2 / / .

[0088] exist Figure 8 In the diagram, the arrows indicate the overlapping direction of the semi-spaced jacquard guide bars JB1 and JB2. The arrows also indicate that when weaving the basic structure, the semi-spaced jacquard guide bars JB1 and JB2 overlap in the opposite direction to the bottom guide guide bars GB3 and GB4.

[0089] exist Figure 9 The diagram illustrates multiple weaving structures created by the half-spaced jacquard guide bars JB1 and JB2 during the operation of the jacquard mechanism. The basic weaving structure of the half-spaced jacquard guide bars JB1 and JB2 is represented by a solid line in the top left column and by dashed lines in the other columns. Additionally, in columns other than the top left, examples of weaving structures formed by the half-spaced jacquard guide bars JB1 and JB2 during the operation of the jacquard mechanism are shown by solid lines. The half-spaced jacquard guide bars JB1 and JB2 are woven into this structure in every part of the warp-knitted fabric. Figure 9 Any one of the weaving structures in it.

[0090] Furthermore, in each knitting pattern diagram, H indicates that the jacquard mechanism is not activated. In this case, the jacquard yarn guide is located in the same position as when knitting the basic structure. Conversely, T indicates that the jacquard mechanism is activated. In this case, the jacquard yarn guide is displaced from the position of the basic structure. T and H indicate the upper and lower segments of a needle position, but the upper segment of T or H indicates whether the jacquard mechanism is activated or not when overlapping, while the lower segment of T or H indicates whether the jacquard mechanism is activated or not when padding the needle back.

[0091] Here Figure 9 In the middle, at the overlapping loop positions of the semi-spaced jacquard combs JB1 and JB2, the jacquard yarn is knitted into the settling arc of the base structure without forming a needle-knit arc due to the action of the folding plate FP.

[0092] On the other hand, Figure 9 In the warp knitting process, at the non-overlapping loop positions of the half-spaced jacquard guide bars JB1 and JB2, the jacquard yarn naturally does not form a needle-knitted arc, and due to the action of the folding plate FP, it is not knitted into the sinker arc of the base fabric. Therefore, at the non-overlapping loop positions of the half-spaced jacquard guide bars JB1 and JB2, the jacquard yarn floats towards the front of the warp-knitted fabric. In other words, if there are non-overlapping loop positions of the half-spaced jacquard guide bars JB1 and JB2, then between the loop positions before and after them (the loop positions where the jacquard yarn is knitted into the sinker arc of the base fabric), the jacquard yarn floats towards the front of the warp-knitted fabric.

[0093] For example, Figure 9 The expanded structure of the upper right woven fabric is as described above. Figure 7 (a) The weave structure. In Figure 7 In (a), the position indicated by the arrow is where the half-spaced jacquard combs JB1 and JB2 perform needle backing without overlapping. In this case, the portion of the jacquard yarn knitted into the sinker arc of the base structure between the two positions floats towards the front of the warp-knitted fabric. Figure 7 As indicated by the double-dotted line in (a), it rises in a shape extending in the longitudinal direction.

[0094] exist Figure 10 In, it means in and Figure 9 A diagram with circular markings was drawn on the same weave structure. In Figure 10 In the middle, the part surrounded by circles of solid lines within the woven structure is the part where the jacquard yarn floats up due to the non-overlapping needle backing of the jacquard combs JB1 and JB2.

[0095] In addition, from Figure 9 The second weave from the left in the top section has an expanded structure, as described above. Figure 7(b) The weave structure. With this weave structure, even at the position where the needle backing yarn is applied across two loops in the half-spaced jacquard combs JB1 and JB2, the jacquard yarn floats towards the front of the warp-knitted fabric between two positions where the jacquard yarn is incorporated into the sinker arc of the base structure. Figure 10 In the middle, the part within the solid lines representing the knitted structure, indicated by wavy brackets (the second column from the left of the top and bottom sections), is the part where the jacquard yarn is raised by needle backing through two loops via half-spaced jacquard combs JB1 and JB2.

[0096] Semi-spaced jacquard comb bars JB1 and JB2 are woven into every part of the warp-knitted fabric. Figure 9 This refers to any one of the multiple weaving structures represented in the diagram. Due to the weaving structure, each section becomes a thick fabric portion or a thin fabric portion relatively thin compared to the thick fabric portion. Furthermore, holes are formed in sections where adjacent loops are not connected by jacquard yarns. Moreover, raised yarn portions, where the jacquard yarns float as described above, are also formed by the weaving structure. Thus, thick fabric portions, thin fabric portions, and holes are formed in each section of the warp-knitted fabric, and raised yarn portions are formed on at least a portion of the warp-knitted fabric, forming a pattern based on them on the warp-knitted fabric.

[0097] In addition, in the semi-spaced jacquard combs JB1 and JB2 weaving Figure 9 In the case of a weaving structure that changes the basic structure, the loop positions where the bottom guide yarn guides GB3 and GB4 and the half-space jacquard guides JB1 and JB2 overlap are opposite to the overlapping directions of the bottom guide yarn guides GB3 and GB4 and the half-space jacquard guides JB1 and JB2.

[0098] exist Figure 11 The middle indicates that it is by Figures 8-10 This is an example of an actual warp-knitted fabric woven using the same weave structure. The warp-knitted fabric consists of the upper sections 17a and 17b, which form the upper of the shoe, and its peripheral section 18. The section indicated by symbol 17a is a thicker fabric, and is where the jacquard yarns are raised to become floating yarns. This section is particularly thick. Furthermore, multiple perforations are formed on the section indicated by symbol 17b within the fabric section. The peripheral section 18 is a thinner fabric, and is also where the jacquard yarns are raised to become floating yarns.

[0099] exist Figure 11 In the warp-knitted fabric, a coarse-count, non-elastic yarn is used as the jacquard yarn supplied from the semi-spaced jacquard combs JB1 and JB2. This non-elastic yarn is, for example, a polyester-processed yarn. Furthermore, the fineness of this non-elastic yarn is, for example, 950 dtex or higher and 1050 dtex or lower. Because a coarse-count yarn is used, a striking three-dimensional texture is created on the warp-knitted fabric.

[0100] In addition, Figure 11 In the warp-knitted fabrics, non-elastic yarn is used as the base yarn supplied from the bottom guide comb GB3 and GB4. This non-elastic yarn is, for example, a polyester processed yarn. In addition, the fineness of this non-elastic yarn is, for example, 85 dtex or more and 120 dtex or less.

[0101] In addition, Figure 11 In the warp-knitted fabric, a non-elastic yarn is used as the insert yarn supplied from the bottom guide bar GB5. This non-elastic yarn is, for example, a polyester monofilament yarn. In addition, the fineness of this non-elastic yarn is, for example, 280 dtex or more and 400 dtex or less.

[0102] in addition, Figure 11 The warp-knitted fabric is a structure woven by supplying yarn to the semi-spaced jacquard combs JB1 and JB2 and the bottom guide combs GB3, GB4 and GB5 in a full warp-through manner.

[0103] from Figure 11 The warp-knitted fabric cut-out parts 17a and 17b are used as the uppers of shoes.

[0104] Next, regarding Figures 12-16 The following example will be used to illustrate this.

[0105] exist Figures 12-16 In this example, the bottom guide bar GB5 is not used. Figure 12 The text indicates the weaving structure formed by the bottom guide combs GB3 and GB4. Additionally, in... Figure 12 The text also indicates the basic structure of the weaving organization formed by the semi-spaced jacquard combs JB1 and JB2.

[0106] The bottom guide bar GB3 is woven with a lockknit structure as the base structure. This lockknit structure is represented by chain numbering as 0-1 / 1-0 / / . Additionally, the bottom guide bar GB4 is woven with a knit structure that mixes the insertion portion and the loop forming portion (referred to as a "mixed structure"). This mixed structure is represented by chain numbering as 1-1 / 0-0 / 0-1 / 0-0 / 1-1 / 1-0 / / . Thus, the base yarn supplied from the bottom guide bar GB3 and the yarn supplied from the bottom guide bar GB4 periodically form double loops, making the yarn less prone to unraveling. Furthermore, because the yarn supplied from the bottom guide bar GB4 is periodically inserted, the force that would cause the yarn to unravel is dispersed.

[0107] exist Figure 12 In the diagram, the solid arrows indicate the overlapping direction of the bottom guide combs GB3 and GB4. The solid arrows also indicate that the lock knit and mixed knit structures overlap in the same direction at the points where the loops are formed in the mixed knit.

[0108] Two half-spaced jacquard guide bars, JB1 and JB2, are woven with different basic structures. The basic structure woven by the front half-spaced jacquard guide bar JB1 is a warp plain weave with closed loops. If this warp plain weave with closed loops is represented by chain numbering, it is 1-0 / 1-2 / / . Conversely, the basic structure woven by the back half-spaced jacquard guide bar JB2 is a warp plain weave with open loops. If this warp plain weave with open loops is represented by chain numbering, it is 2-1 / 0-1 / / .

[0109] exist Figure 12 In the diagram, the solid arrows indicate the overlapping direction of the half-gauge jacquard guide bars JB1 and JB2. Arrow 12 also indicates that the half-gauge jacquard guide bars JB1 and JB2 overlap in the opposite direction to the bottom guide guide bars GB3 and GB4 when weaving the basic structure.

[0110] In addition, Figure 12 In the diagram, the dashed arrows indicate the direction of the needle backing yarn in half-spaced jacquard guide bars JB1 and JB2. As the dashed arrows show, the needle backing yarn directions are opposite in the front half-spaced jacquard guide bar JB1 and the rear half-spaced jacquard guide bar JB2. That is, the two half-spaced jacquard guide bars JB1 and JB2 are engaged in what is called reverse winding. Reverse winding can be achieved by dividing the front jacquard yarn path and the rear jacquard yarn path sequentially.

[0111] exist Figure 13 The text indicates multiple weaving structures woven by the front half-spaced jacquard guide bar JB1 during the operation of the jacquard mechanism. Additionally, in... Figure 14 The middle part indicates the multiple weaving structures woven by the rear half-spaced jacquard comb JB2 when the jacquard mechanism is in operation.

[0112] exist Figure 13 and Figure 14 In the diagram, the basic weave structure of the half-spaced jacquard guide bars JB1 and JB2 is indicated by solid lines in the top left column and by dashed lines in the other columns. Additionally, in columns other than the top left, examples of the weave structure formed by the half-spaced jacquard guide bars JB1 and JB2 during the operation of the jacquard mechanism are shown by solid lines. The front half-spaced jacquard guide bars JB1 are woven into every part of the warp-knitted fabric. Figure 13 Any one of the weaving structures in the fabric. Additionally, the semi-spaced jacquard comb JB2 on the back is woven into every part of the warp-knitted fabric. Figure 14 Any one of the knitting groups.

[0113] exist Figure 13 and Figure 14 In the knitting structure, at the overlapping loop positions of the semi-spaced jacquard combs JB1 and JB2, the jacquard yarn is knitted into the settling arc of the base structure without forming a needle-knit arc due to the action of the folding plate FP.

[0114] In addition, with Figure 9 and Figure 10 The same applies to the woven structure shown. Figure 13 and Figure 14 In the knitting structure, at the non-overlapping loop positions of the half-spaced jacquard guide bars JB1 and JB2, the jacquard yarn naturally does not form a needle-knitted arc, and due to the action of the folding plate FP, it is not knitted into the sinker arc of the base structure. Therefore, at the non-overlapping loop positions of the half-spaced jacquard guide bars JB1 and JB2, the jacquard yarn floats towards the front of the warp-knitted fabric. In other words, if there are non-overlapping loop positions of the half-spaced jacquard guide bars JB1 and JB2, the jacquard yarn floats towards the front of the warp-knitted fabric between the front and rear loop positions (the loop positions where the jacquard yarn is knitted into the sinker arc of the base structure).

[0115] exist Figure 15 In, it means in and Figure 14 A diagram with circular markings was drawn on the same weave structure. In Figure 15 The part surrounded by circles of solid lines within the solid lines representing the weave structure is the part where the jacquard yarn floats up due to the non-overlapping needle backing of the jacquard combs JB1 and JB2.

[0116] In addition, Figure 13 and Figure 14 In the middle, at the position where the jacquard combs JB1 and JB2 are used for needle backing yarn in two loops along the warp, the jacquard yarn also floats towards the front of the warp-knitted fabric. The jacquard yarn floats out between two positions where the jacquard yarn is knitted into the settling arc of the base structure. Figure 15 In the middle, the part within the solid lines representing the knitted structure, indicated by wavy brackets (the first and third columns from the left in the second layer from the top), is the part where the jacquard yarn is raised by needle backing through two loops via half-spaced jacquard combs JB1 and JB2.

[0117] Semi-spaced jacquard comb bars JB1 and JB2 are woven into every part of the warp-knitted fabric. Figure 13 and Figure 14 The text refers to any one of the multiple weaving structures represented in the diagram. Therefore, thick weave sections, thin weave sections, and holes are formed at each part of the warp-knitted fabric, thereby forming raised yarn sections on at least a portion of the warp-knitted fabric and creating a pattern based on them on the warp-knitted fabric.

[0118] In addition, in the semi-spaced jacquard combs JB1 and JB2 weaving Figure 13 and Figure 14In the case of a weaving structure that changes the basic structure, the overlapping loop positions of the bottom guide yarn guides GB3 and GB4 and the half-space jacquard guides JB1 and JB2 are opposite to those of the bottom guide yarn guides GB3 and GB4.

[0119] In addition, two half-spaced jacquard combs, JB1 and JB2, are woven separately. Figure 13 and Figure 14 In the case of a knitting structure that changes the basic structure, when both sides of the two half-spaced jacquard combs JB1 and JB2 are needle backing yarns in the same loop row, the needle backing yarns in the front half-spaced jacquard comb JB1 and the back half-spaced jacquard comb JB2 are also opposite in direction.

[0120] exist Figure 16 In (a), it indicates that the method used was... Figures 12-15 Example of a warp-knitted garment 19. The three-dimensional pattern formed on this garment 19 is a pattern formed by a jacquard weave.

[0121] The warp-knitted fabric used in this garment 19 is 100% cotton. The yarn supplied from the bottom guide comb GB3 and GB4 is cotton yarn with a fineness of, for example, 280 dtex or more and 320 dtex or less, and the jacquard yarn is cotton yarn with a fineness of, for example, 1160 dtex or more and 1200 dtex or less.

[0122] In addition, the warp-knitted fabric used in this garment 19 is a warp-knitted fabric that is woven by supplying yarn to the semi-spaced jacquard combs JB1 and JB2 and the bottom guide combs GB3 and GB4 in a full-warp-through manner.

[0123] exist Figure 16 In (b), Figure 16 (a) is represented by an enlarged portion of garment 19. In this portion, holes are formed throughout, causing the jacquard yarns to float as lifting yarns. This warp-knitted fabric, by periodically forming holes and using coarse yarns as described above, becomes a coarse warp-knitted fabric that appears similar to a crocheted fabric.

[0124] Next, the effects of this embodiment will be explained.

[0125] In addition to the bottom guide yarn guides GB3, GB4, and GB5, the warp knitting machine of this embodiment also includes a pleated plate FP and two semi-spaced jacquard guides JB1 and JB2 positioned in front of the pleated plate FP. Therefore, it is possible to knit a pleated plate hanging yarn structure, and further, to knit a different knitting structure in each part of the warp-knitted fabric.

[0126] Here, because the two semi-spaced jacquard guide bars JB1 and JB2 are positioned in front of the folding plate FP, the folding plate FP pushes the jacquard yarn down from the hook 11 of the knitting needle 10 during knitting. Therefore, the requirements for the jacquard yarn are fewer for knitting warp-knitted fabrics. For example, even if a thick yarn that does not enter the hook 11 of the knitting needle 10 is used as the jacquard yarn, knitting can still be performed.

[0127] Furthermore, in conventional warp knitting machines equipped with two half-spaced jacquard guide bars, jacquard yarn is supplied to the two half-spaced jacquard guide bars from the same yarn path (for example, jacquard yarn is supplied from the front to the two half-spaced jacquard guide bars compared to the front half-spaced jacquard guide bar). Therefore, if the two half-spaced jacquard guide bars are to be wound in opposite directions with opposite needle backing yarn directions, the yarn of the front half-spaced jacquard guide bar JB1 and the yarn of the rear half-spaced jacquard guide bar JB2 cross, hindering knitting.

[0128] In contrast, in this embodiment of the warp knitting machine, the multiple jacquard yarn guides of the front half-spaced jacquard guide bar JB1 each have multiple yarn paths that supply jacquard yarn from the front compared to the front half-spaced jacquard guide bar JB1. Furthermore, in this embodiment of the warp knitting machine, the multiple jacquard yarn guides of the rear half-spaced jacquard guide bar JB2 each have multiple yarn paths that supply jacquard yarn from the rear compared to the rear half-spaced jacquard guide bar JB2. Because the yarn paths are divided front and rear in this way, it is possible to prevent the yarns of the front half-spaced jacquard guide bar JB1 and the rear half-spaced jacquard guide bar JB2 from crossing. For example, when two half-spaced jacquard combs JB1 and JB2 are wound in opposite directions, it can prevent the yarns of the front half-spaced jacquard comb JB1 and the rear half-spaced jacquard comb JB2 from crossing.

[0129] Furthermore, the warp knitting machine of this embodiment includes a warp frame that can adjust the yarn feed amount for each yarn, supplying jacquard yarn one by one to the multiple jacquard guides of the two semi-spaced jacquard guide bars JB1 and JB2. Therefore, an appropriate amount of yarn corresponding to the various movements of the multiple jacquard guides of the semi-spaced jacquard guide bars JB1 and JB2 can be fed from the warp frame to their respective jacquard guides.

[0130] As described above, based on the structure of the warp knitting machine of this embodiment, it is possible to smoothly knit warp-knitted fabrics with patterns that vary depending on the location.

[0131] Furthermore, the warp knitting machine of this embodiment has a take-up path that takes the warp-knitted fabric from the knitting needle row to the take-up device. It also includes a fiber dust prevention device, which has an air supply device 21 that supplies air to one side of the warp-knitted fabric passing through the take-up path and a suction device 22 that draws air from the other side of the warp-knitted fabric passing through the take-up path. Thus, when short-fiber yarns such as cotton yarn are used as the warp-knitted fabric, the fiber dust prevention device can draw away flying fibers by the suction device 22. Therefore, the warp knitting machine and the operator are protected from short-fiber yarns.

[0132] Furthermore, in the weaving method of this embodiment, bottom guide bars GB3, GB4, and GB5 weave the base structure, and semi-spaced jacquard guide bars JB1 and JB2 weave the jacquard structure. Moreover, during the weaving of the jacquard structure, the folding plate FP acts on the jacquard yarns suspended on the knitting needles 10 by the two semi-spaced jacquard guide bars JB1 and JB2. Due to the action of the folding plate FP, the jacquard yarns are woven into the sinker arc of the base structure without forming a needle arc at the needle arc position. Furthermore, in a portion of the warp-knitted fabric, the jacquard yarns become a structure that floats between two loop positions. Thus, it is possible to weave warp-knitted fabrics with patterns varying depending on the location.

[0133] Here, compared to the front half-pitch jacquard guide bar JB1, the jacquard yarn is supplied to the multiple jacquard yarn guides of the front half-pitch jacquard guide bar JB1 via the front yarn path, and compared to the rear half-pitch jacquard guide bar JB2, it is supplied to the multiple jacquard yarn guides of the rear half-pitch jacquard guide bar JB2 via the rear yarn path. Therefore, it is possible to prevent the yarn of the front half-pitch jacquard guide bar JB1 and the yarn of the rear half-pitch jacquard guide bar JB2 from crossing. For example, when the two half-pitch jacquard guide bars JB1 and JB2 are wound in opposite directions, it is possible to prevent the yarn of the front half-pitch jacquard guide bar JB1 and the yarn of the rear half-pitch jacquard guide bar JB2 from crossing.

[0134] Furthermore, for the weaving of the jacquard structure, jacquard yarns are fed one by one from the warp frame, where the yarn feed amount for each yarn can be adjusted, to multiple jacquard yarn guides on the two semi-spaced jacquard guide bars JB1 and JB2. Therefore, it is possible to feed appropriate amounts of yarn from the warp frame to their respective jacquard yarn guides, corresponding to various movements of the multiple jacquard yarn guides on the semi-spaced jacquard guide bars JB1 and JB2.

[0135] As described above, based on the weaving method of this embodiment, it is possible to smoothly weave warp-knitted fabrics with patterns that vary depending on the location of the warp.

[0136] Furthermore, in the weaving method of this embodiment, the air supply device 21 supplies air to one side of the warp-knitted fabric, while the suction device 22 draws air from the other side of the warp-knitted fabric. Therefore, when short-fiber yarns such as cotton yarn are used as the warp-knitted fabric, the suction device 22 can draw in any flying fibers.

[0137] Furthermore, at the same loop position, with the overlapping directions of the bottom guide combs GB3 and GB4 and the semi-spaced jacquard combs JB1 and JB2 being the same, there is a greater contact area between the bottom yarn and the jacquard yarn. Therefore, in this situation, when the folding plate FP pushes down the jacquard yarn, there is a risk that it may also push down the bottom yarn.

[0138] However, in this embodiment, at the same coil position, when the bottom guide yarn combs GB3 and GB4 and the half-spaced jacquard combs JB1 and JB2 overlap, the overlapping direction of the bottom guide yarn combs GB3 and GB4 is opposite to that of the half-spaced jacquard combs JB1 and JB2. Therefore, the contact portion between the bottom yarn and the jacquard yarn is small, and when the folding plate FP pushes down the jacquard yarn, the bottom yarn can be hung on the needle hook 11 without being pushed down and form a needle-knitted arc.

[0139] The above-described embodiments are merely one example of the present invention. Various modifications can be made relative to the above-described embodiments. Modifications that are appropriately made without departing from the spirit of the present invention are considered as modifications included within the scope of the present invention.

[0140] For example, the number of bottom guide bars on the warp knitting machine can be one, two, or more than four. Furthermore, the base structure knitted by the bottom guide bars is not limited to... Figure 8 , Figure 12 The basic weave structure of the semi-spaced jacquard comb JB1 and JB2 is not limited to...
