Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of jacquard fabric processing, in particular to a 3D jacquard fabric with a fishing line sandwich layer and a warp knitting machine. BACKGROUND

[0002] The jacquard fabric is a kind of fabric woven by a jacquard warp knitting machine, and the jacquard warp knitting machine is a device that can produce complex patterns on a weaving machine or a knitting machine. The weaving process of the jacquard fabric can be divided into the following steps: first, the warp yarns need to be drawn from the warp beam and inserted into the guide needles of the guide bar, and the guide needles move around the needles to form a shedding motion diagram. Secondly, different jacquard shedding motions can form different jacquard organization effects, such as loose weave, mesh weave and thick weave. According to the combination of the loose weave, mesh weave and thick weave, a variety of pattern designs can be woven, such as strip patterns and geometric patterns. The pattern design can be controlled by a jacquard card. Finally, the needles move up and down at the same time to form loops with the yarns laid on the needles, forming a jacquard warp-knitted fabric. The front and back of the jacquard warp-knitted fabric can have different organization structures and pattern effects.

[0003] The existing jacquard fabric has corresponding concave-convex patterns on the inner and outer layers due to the limitation of the weaving process, that is, the inner layer of the fabric is also concave-convex and not smooth. When used as clothing or shoe material, a smooth fabric needs to be sewn on the inner lining to reduce the skin's feeling of the concave-convex surface. SUMMARY

[0004] Since the existing jacquard fabric has a concave-convex pattern on the inner surface after processing, the skin feeling is affected. The present application provides a 3D jacquard fabric with a fishing line sandwich layer and a warp knitting machine.

[0005] The following technical solutions are adopted:

[0006] In a first aspect,

[0007] A 3D jacquard fabric with a fishing line sandwich layer is provided, which includes a base organization layer and a pattern layer woven integrally. The pattern layer includes at least a first pattern layer and a second pattern layer, which are woven on the base organization layer in sequence. The first pattern layer is woven with elastic threads, and the second pattern layer is woven with ordinary yarns. The second pattern layer includes graphic organizations and mesh organizations, which cooperate to form a jacquard pattern.

[0008] By adopting the above technical solutions, an elastic thread layer is added in the middle of the jacquard fabric, so that the jacquard fabric not only has greater elasticity, but also can effectively separate the inner and outer layers of the fabric through the elastic thread in the middle. Such a jacquard fabric can be directly used as a fabric for clothing or shoes without the need for an inner lining.

[0009] Optionally, the ordinary yarn is a low-elasticity colored yarn of 75D-300D.

[0010] By adopting the above technical solution, ordinary yarn is selected from low-elasticity colored yarn of 75D-300D, which helps to improve the comfort of wearing.

[0011] Optionally, the elastic thread is made of polyamide fiber.

[0012] By adopting the above technical solution, polyamide fibers have hardness and appropriate elasticity, which can support the jacquard pattern after being woven into fabric, and the structure is more stable.

[0013] Optionally, the elastic thread material is polyethylene fiber.

[0014] By adopting the above technical solution, polyethylene fiber has appropriate hardness and elasticity, which can support the Jacquard pattern after being woven into fabric, and the structure is more stable.

[0015] Secondly,

[0016] A warp knitting machine is provided for knitting 3D jacquard fabric with a fishing line interlayer, comprising a machine body, a plurality of basic guide bars and a plurality of elastic thread guide bars, wherein the plurality of basic guide bars and the plurality of elastic thread guide bars are distributed in a semi-circular pattern on the machine body, wherein the basic guide bars are threaded with ordinary yarn and the elastic thread guide bars are threaded with elastic thread.

[0017] By adopting the above technical solution, elastic yarn combs are added to the warp knitting machine to increase the production efficiency of blending ordinary yarn and elastic yarn.

[0018] Optionally, the machine body includes a base, a crossbeam, a fixed frame, and a movable frame. The crossbeam is disposed above the base. One end of the fixed frame is fixed to the crossbeam, and the other end extends inclined towards the base. A plurality of basic combs and a plurality of elastic wire combs are evenly spaced and connected to the fixed frame. One end of the movable frame is rotatably connected to the crossbeam, and the other end extends inclined in the opposite direction to the fixed frame. A plurality of basic combs and a plurality of elastic wire combs are evenly spaced and connected to the movable frame.

[0019] By adopting the above technical solution, some of the basic guide bars and elastic guide bars are installed on the movable frame. The movable frame can be rotated relative to the middle of the crossbeam to open the warp knitting machine, thereby separating some of the basic guide bars and elastic guide bars from the other part, while making enough space for operators to enter, which facilitates efficient yarn threading.

[0020] Optionally, the base includes a connecting bracket, and the end of the movable frame away from the crossbeam is detachably connected to the connecting bracket.

[0021] Optionally, the crossbeam comprises a main beam and a sub-beam, and the moving frame and the fixed frame are connected to the lower end surface of the main beam near the sub-beam, and the lower surface of the sub-beam is higher than the lower surface of the main beam.

[0022] By adopting the above technical scheme, the rotation of the moving frame is provided with a space by the sub-beam, so that the opening degree of the moving frame is sufficient. The operator can conveniently thread the yarn.

[0023] Optionally, the moving frame is rotatably connected to the crossbeam through a horizontal shaft, and damping oil is arranged between the horizontal shaft and the crossbeam.

[0024] By adopting the above technical scheme, the resistance during rotation between the crossbeam and the horizontal shaft is increased, so as to avoid that the common yarn or elastic thread is quickly pulled after the rotation of the moving frame, thereby causing breakage or separation from the guide bar.

[0025] Optionally, the rotation angle of the moving frame is greater than 90 degrees.

[0026] By adopting the above technical scheme, sufficient space for the operator to enter is provided.

[0027] In summary, the present application has at least one of the following beneficial effects:

[0028] 1. An elastic thread is added in the middle of the jacquard cloth, the inner and outer layers of the cloth are effectively separated, and the second pattern layer is formed by the elastic support in the middle, so that the jacquard cloth can be directly used as a fabric of a garment or a shoe;

[0029] 2. Part of the base guide bar and the elastic thread guide bar are installed on the moving frame, the moving frame is rotated to open the space in the warp knitting machine, and sufficient space is provided for the operator to enter, thereby facilitating efficient threading.

DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying Figure 1 to the accompanying Figure 2 The present application will be further described in detail.

[0034] Embodiment One

[0035] With reference to Figure 1 , the embodiment of the present application discloses a 3D jacquard fabric with a fishline layer, which comprises a base layer 1 and a jacquard layer woven by a warp knitting machine. The jacquard layer comprises a first jacquard layer 2 and a second jacquard layer 3 woven by mixing, and the first jacquard layer 2 and the second jacquard layer 3 are sequentially woven on the base layer 1, wherein the first jacquard layer 2 is woven by elastic threads 21. The main feature of the jacquard fabric is that it has mesh holes, and the second jacquard layer 3 is the main structure for forming the pattern of the jacquard fabric. The second jacquard layer 3 comprises patterned structures 31 and mesh structures 32, and the patterned structures 31 and the mesh structures 32 are arranged alternately, and the patterned structures 31 and the mesh structures 32 cooperate to form a jacquard layer pattern. The elastic threads 21 correspond to the positions of the patterned structures 31, and the elastic threads 21 support the patterned structures 31 to form a convex surface of the jacquard layer. Compared with the prior art, weaving the jacquard layer on the base layer 1 will cause the base layer 1 to have a concave-convex weaving pattern corresponding to the jacquard layer at the bottom, and an inner lining needs to be sewn at the bottom of the fabric to cover the concave-convex weaving pattern at the bottom of the fabric and improve the skin feel. The present application mixes elastic threads 21 into the first jacquard layer 2 on the base layer 1, provides support for the patterned structures 31 of the second jacquard layer 3, so that the first jacquard layer 2 directly woven on the base layer 1 is uniformly arranged, and thus there is no concave-convex weaving pattern, so that when the fabric directly contacts the skin, the skin feel is better.

[0036] With reference to Figure 1 , further, the second jacquard layer 3 is woven by ordinary yarn. The material of the ordinary yarn is not limited too much, and can be selected from commonly used materials in the industry. In this embodiment, the preferred material is low-elastic colored yarn with a fineness of 75D-300D.

[0037] With reference to Figure 1 , further, the material of the elastic threads 21 can be selected from polyamide fiber or polyethylene fiber (i.e., the material of the fishline). The material hardness of the polyamide fiber or the polyethylene fiber is in a suitable range, and when the elastic threads 21 of the first jacquard layer 2 are mixed with the ordinary yarn of the second jacquard layer 3, the elastic threads 21 can support the structure of the first jacquard layer 2 to remain stable due to the hardness thereof, and after the second jacquard layer 3 is woven, the elastic threads 21 can effectively support the patterned structures 31 to be convex, thereby forming a surface pattern. After the fabric is deformed under stress, the elastic threads 21 are deformed under stress, and since the material elasticity of the polyamide fiber or the polyethylene fiber is in a suitable range, the elastic threads 21 always have a tendency to return to the initial state, thereby keeping the structure stable after the deformation of the fabric, and enabling the patterned structures 31 of the second jacquard layer 3 to return to the initial state after the deformation.

[0038] Further, when the cloth is woven, the guide bar should be fully inserted throughout the pattern cycle, and each longitudinal row has a loop of the guide bar. The guide bar is divided into two types, the ordinary guide bar for inserting ordinary yarn and the special guide bar for inserting the elastic yarn 21. The ordinary guide bar drives the ordinary yarn to form the front and back of the base layer 1 of the jacquard cloth, and the special guide bar inserts the elastic yarn 21 into the front of the base layer 1 while the base layer 1 is being woven. In the pattern layer, the guide bar drives the ordinary yarn or the elastic yarn 21 to weave into loops, and the change of the number of loops changes the pattern from dense to sparse. In the pattern layer, in order to ensure the balance of tension, the guide bar is offset when the needle is padded in front of the guide bar, and the guide bar is not woven into loops, but the needle is offset when the guide bar is padded in front of the opposite guide bar, and the guide bar is woven into loops, thereby ensuring the balance of yarn tension, which is also the reason for forming the long and short meshes.

[0039] The implementation principle of the embodiment is:

[0040] In the middle layer of the jacquard cloth, a first pattern layer 2 is woven by adding a layer of elastic yarn 21, and the material of the elastic yarn 21 is polyamide fiber or polyethylene fiber. Such jacquard cloth not only has greater elasticity, but also can effectively separate the inner and outer layers of the cloth through the elastic yarn 21 in the middle, and form the convex texture of the second pattern layer 3 through the elastic support in the middle. Such jacquard cloth can be directly used as a fabric for clothing or shoes. Unlike existing cloth, it does not need to add a smooth cloth lining to reduce the feeling of the skin to the rough surface of the cloth inner wall. In addition, the breathability of the jacquard cloth is also improved.

[0041] Embodiment two:

[0042] Due to the special properties of the elastic yarn 21, the disc head of the elastic yarn 21 needs to be installed independently. In order to process the above-mentioned cloth, an elastic yarn guide bar 8 for conveying the elastic yarn 21 needs to be added to the existing guide bar device. When the disc head needs to be replaced, the elastic yarn 21 needs to be reconnected. Due to the fact that the traditional ordinary yarn cannot be connected in the same way as the traditional ordinary yarn, it is necessary to reconnect all the yarns at the beginning, and at this time, due to the traditional guide bar device, the electronic guide bar is clamped in the middle, which cannot be disassembled, and only one by one can be reconnected, because the number of yarns involved is several thousand, which brings great inconvenience and low efficiency. Therefore, the embodiment provides a warp knitting machine for weaving 3D patterned jacquard cloth with a fish line sandwich.

[0043] Reference Figure 2, specifically, the warp knitting machine includes a machine body, a plurality of base guide bars 7 and a plurality of elastic thread guide bars 8, the machine body is used to carry all processing structures of the warp knitting machine, the machine body adopts a split structure and includes a bottom machine, a cross beam 4, a fixed frame 5 and a moving frame 6. The plurality of base guide bars 7 and the plurality of elastic thread guide bars 8 are distributed in a semicircle on the machine body, the base guide bars 7 are provided with ordinary yarns, and the elastic thread guide bars 8 are provided with elastic threads 21.

[0044] With reference to Figure 2 Further, one end of the fixed frame 5 is fixed to the cross beam 4, and the other end extends obliquely to the bottom machine, and the base guide bars 7 and the elastic thread guide bars 8 are uniformly and alternately connected to the fixed frame 5. One end of the moving frame 6 is rotatably connected to the cross beam 4, and the other end extends obliquely to the bottom machine, and the moving frame 6 extends in the opposite direction of the fixed frame 5, and the base guide bars 7 and the elastic thread guide bars 8 are also uniformly and alternately connected to the moving frame 6. The bottom machine includes a connecting support 9, the moving frame 6 is connected to the bottom machine through the connecting support 9, and the moving frame 6 and the connecting support 9 are detachably connected. In this embodiment, the connection between one end of the moving frame 6 and the connecting support 9 adopts a bolt connection mode, and in other embodiments, other conditions can exist, which are not limited.

[0045] With reference to Figure 2 Further, one end of the fixed frame 5 is fixed to the cross beam 4, and the other end extends obliquely to the bottom machine, and the base guide bars 7 and the elastic thread guide bars 8 are uniformly and alternately connected to the fixed frame 5. One end of the moving frame 6 is rotatably connected to the cross beam 4, and the other end extends obliquely to the bottom machine, and the moving frame 6 extends in the opposite direction of the fixed frame 5, and the base guide bars 7 and the elastic thread guide bars 8 are also uniformly and alternately connected to the moving frame 6. The bottom machine includes a connecting support 9, the moving frame 6 is connected to the bottom machine through the connecting support 9, and the moving frame 6 and the connecting support 9 are detachably connected. In this embodiment, the connection between one end of the moving frame 6 and the connecting support 9 adopts a bolt connection mode, and in other embodiments, other conditions can exist, which are not limited.

[0046] Further, the moving frame 6 is rotatably connected to the cross beam 4 through a horizontal shaft 61, the horizontal shaft is arranged along the length direction of the cross beam 4, and a damping structure can be arranged between the horizontal shaft 61 and the cross beam 4. In this embodiment, the preferred damping structure is to use electromagnetic or damping oil. The resistance between the cross beam 4 and the horizontal shaft 61 during rotation is increased, so that the rotation of the moving frame 6 is more stable. In order to avoid that the ordinary yarn or the elastic thread 21 is quickly pulled after the moving frame 6 rotates, resulting in breakage or separation from the guide bar.

[0047] With reference to Figure 2Furthermore, the crossbeam 4 includes a main beam 41 and a secondary beam 42. One end of the movable frame 6 and the fixed frame 5 are both connected to the lower end face of the main beam 41 near the secondary beam 42. The bottom of the secondary beam 42 is higher than the bottom of the main beam 41, forming a clearance space and a stepped structure to allow the movable frame 6 to rotate and make room. Preferably, the rotation angle of the movable frame 6 is greater than 90 degrees. Since the movable frame 6 needs to open to a certain degree to allow sufficient space for the operator to thread the elastic yarn guide bar 8, and traditional warp knitting machines are double-headed, with the crossbeam 4 symmetrically arranged on both sides to connect two structures similar to the fixed frame 5, in this embodiment, to ensure sufficient opening of the movable frame 6, the structure of the crossbeam 4 is adjusted to both meet the opening requirements of the guide bar frame and ensure the overall strength of the beam structure. A vertical guideway 43 is provided between the main beam 41 and the secondary beam 42. The structure of the main beam 41 and the secondary beam 42 also allows for intermediate space to be allocated, facilitating the threading of intermediate yarns and significantly saving space that would otherwise be needed for rearranging yarns on the sides. As a result, the yarn tray can be directly mounted on the top of the comb frame, which not only facilitates the fixed placement of the tray but also saves space required for yarn winding.

[0048] The implementation principle of a warp knitting machine in this embodiment is as follows:

[0049] By installing some of the basic guide bars 7 and elastic guide bars 8 on the movable frame 6, the movable frame 6 can be rotated relative to the middle of the crossbeam 4 to open the warp knitting machine, thereby separating some of the basic guide bars 7 and elastic guide bars 8 from the other part, while making enough space for operators to enter, which facilitates efficient yarn threading.

[0050] Meanwhile, the secondary beam 42 is positioned to allow for the rotation of the movable frame 6, ensuring sufficient opening of the movable frame 6 to facilitate yarn threading by the operators.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
