Description

Technical Field

[0001] The invention relates to the technical field of mesh cloth, in particular to a sandwich mesh cloth with three-dimensional carved jacquard and a manufacturing method thereof. Background Art

[0002] Sandwich mesh is a double needle bed warp knitted mesh, which consists of a mesh surface, connected monofilaments, and a flat bottom. Because its three-dimensional mesh structure is very similar to a Western sandwich hamburger, it is named sandwich mesh.

[0003] With the development of social economy and fashion trends, people have higher and higher requirements for the aesthetics of sandwich meshes. Therefore, sandwich meshes with relief effects have appeared on the market. The Chinese utility model patent (authorization announcement number CN205000062U) discloses a mesh with relief texture and hollow dark pattern. The bottom layer of the fabric body is provided with a hollow dark pattern tissue layer and a relief texture contour layer. The hollow dark pattern tissue layer is formed by weaving 20D nylon, and the relief texture contour layer is formed by alternately splicing and weaving 75D flower comb nylon and 420D nylon core-spun yarn. The mesh is a woven mesh. The patent uses the thickness of the yarn to form the hollow dark pattern in the concave part and the convex relief texture contour. The mesh of the patent has poor air permeability and only has a concave and convex relief effect. There is no obvious concave and convex touch and visual sense of carving, and it does not have a hollow effect. Summary of the invention

[0004] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures specifically pointed out in the description, claims and other drawings of the description.

[0005] The object of the present invention is to overcome the above-mentioned shortcomings and provide a sandwich mesh with three-dimensional hollow jacquard, which is woven integrally by a double-needle-bar high-speed warp knitting machine or a double-needle-bar high-speed jacquard machine. The mesh includes a hollow jacquard layer, a hollow layer and a hollow base layer. The three-dimensional hollow jacquard is woven by the yarn threading changes of the comb bar and the local missed needle process, so that the mesh has good air permeability, wrinkle resistance, shape retention, strong 3D stereoscopic sense, and strong hollow effect, breaking through the technical difficulties of the prior art mesh that is poor in air permeability, has no obvious concave-convex tactile and visual sense, has only a concave-convex relief effect, and has no hollow effect.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a sandwich mesh with three-dimensional carved jacquard, including a mesh body woven by a double-needle bed high-speed warp knitting machine or a double-needle bed high-speed jacquard machine, the mesh body including a carved jacquard layer, a carved layer and a carved base layer; the carved jacquard layer includes a three-dimensional carved jacquard, the three-dimensional carved jacquard includes a plurality of coil structures, a plurality of hollow holes, the coil structure includes a plurality of first yarns, a plurality of the first yarns are cross-woven to form the coil structure, and the coil structure includes a looped coil structure , a loose coil organization, an extended coil organization, the hollow hole is woven between the coil organization and the coil organization; the carved layer is woven below the carved jacquard layer, the carved layer includes a plurality of second yarns, and a plurality of the second yarns are cross-woven to form the carved layer; the carved base layer is woven below the carved layer, the carved base layer includes a plurality of third yarns, and a plurality of the third yarns are cross-woven to form the carved base layer, a plurality of air-permeable hole organizations are woven on the carved base layer, and the air-permeable hole organization can be a plain air-permeable hole organization or a gradient air-permeable hole organization. The mesh body is woven by a double-needle-bed high-speed warp knitting machine. The mesh body includes a hollow jacquard layer, a hollow layer and a hollow base layer. The three-dimensional hollow jacquard is woven by the yarn threading changes of the comb bar and the local missed needle process. The mesh has good air permeability, wrinkle resistance, and shape retention. It has a strong 3D stereoscopic sense and a strong hollow effect. It breaks through the technical difficulties of the existing mesh technology, such as poor air permeability, no obvious concave and convex touch and visual sense, only a concave and convex relief effect, and no hollow effect.

[0007] Preferably, the hollow layer is connected to the looped coil structure and the hollow base layer, so that the mesh body does not delaminate and the structure is more stable.

[0008] Preferably, the carved layer is connected to the loose coil structure (the loose coils cannot be woven into a loop due to the carved jacquard process) and the carved base layer, so that the loose coil structure is not affected by tension and is not easily unhooked, and has strong shape retention.

[0009] Preferably, the hollow layer is connected to the extended coil structure (because the hollow jacquard process cannot complete the coil extension line for loop weaving) and the hollow base layer, and the hollow layer pulls the extended coil structure downward, so that the structural stability of the mesh body is high.

[0010] Preferably, the hollow jacquard layer is a single-comb hollow jacquard layer, a multi-comb hollow jacquard layer, a geometric hollow jacquard layer or an irregular pattern hollow jacquard layer.

[0011] Preferably, the denier of the first yarn is greater than the denier of the second yarn, and the denier of the first yarn is greater than the denier of the third yarn. The greater the denier of the first yarn, the thicker the first yarn, so that the three-dimensional carved jacquard in the carved jacquard layer has a stronger three-dimensional sense, a more prominent concave-convex touch, and a more obvious concave-convex visual sense.

[0012] Preferably, the first yarn is one or a combination of colored yarn, luminous yarn, and reflective yarn. The colored yarn can be a mixed linen low-elastic yarn or a space-dyed fantasy low-elastic yarn, which is used to enrich the color of the three-dimensional carved jacquard; at the same time, it can be matched with luminous yarn and reflective yarn, and the luminous and reflective properties of the yarn can be used to make the mesh cloth clearly feel the luminous carved effect of the carved jacquard sandwich mesh cloth in a weak light environment.

[0013] Preferably, the second yarn is a transparent yarn or an elastic yarn. The transparent yarn can be transparent fish silk, TPU monofilament, TPEE monofilament or high-strength monofilament, which greatly enhances the transparent visual effect; by using elastic yarn for weaving, the mesh has stronger extensibility.

[0014] Preferably, the third yarn is one or a combination of two or more of colored yarn, transparent yarn and elastic yarn.

[0015] Preferably, the number of spinnerets (F number) of the first yarn and the third yarn is greater than the number of spinnerets (F number) of the second yarn. Since the number of spinnerets (F number) of the first yarn and the third yarn is greater than the number of spinnerets (F number) of the second yarn, the texture of the carved jacquard layer and the carved base layer is softer, making the overall hand feel of the mesh cloth softer.

[0016] The present invention also provides a method for manufacturing the sandwich mesh with three-dimensional carved jacquard as described above, comprising the following steps:

[0017] S1. Comb setting: Use a double needle bed high-speed warp knitting machine or a double needle bed high-speed jacquard machine for knitting, a double needle bed high-speed warp knitting machine or a double needle bed high-speed jacquard machine having at least 4 combs, 4 combs from the front needle bed to the rear needle bed are provided with a ground comb comb GB1, a ground comb comb GB2, a ground comb comb GB3, a ground comb comb GB4;

[0018] S2.

[0021] Preferably, in the knitting step, the ground comb bar GB2 performs loop knitting on the front needle bed, and the ground comb bar GB3 performs loop knitting on the rear needle bed.

[0022] Preferably, in the threading step, the ground comb bar GB1 uses two yarns as one yarn to thread the yarn. By threading the yarns with two yarns as one yarn, the D number of the yarn is increased, and the concave-convex touch and visual sense of the engraving effect are enhanced.

[0025] 2. The three-dimensional hollow jacquard of the mesh body can be a single-comb hollow jacquard or a multi-comb hollow jacquard, and can be matched with some colored yarns to enrich the color of the three-dimensional hollow jacquard, and matched with some luminous yarn and reflective yarn. The luminous and reflective properties of the yarn are used to make the mesh clearly feel the luminous hollow effect of the hollow jacquard sandwich mesh in a weak light environment.

[0026] 3. The present invention arranges the comb bar for weaving the hollow layer to adopt a double needle bed process, and the yarns are alternately laid in the front needle bed and the rear needle bed to form loops for weaving, so that the structure of the sandwich mesh is more stable.

[0027] 4. The comb bar for weaving the hollow jacquard layer in the present invention uses two yarns and one yarn to thread the yarn, thereby increasing the D number of the yarn and enhancing the concave-convex touch and visual sense of the hollow effect.

[0028] 5. The manufacturing method of the present invention is simple, and the three-dimensional carved jacquard 11 is woven by using the yarn threading change of the comb and the local missing needle process, so that the sandwich mesh has a strong 3D stereoscopic sense, a strong carving effect, and a more prominent concave and convex sense, which greatly enhances the tactile and visual sense of the concave and convex.

[0057] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0058] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.

[0059] Example 1

[0060] Reference Figure 1 , Figure 1 It is a cross-sectional view of the sandwich mesh with three-dimensional carved jacquard of the present invention.

[0061] The present embodiment provides a sandwich mesh with a three-dimensional hollow jacquard 11, comprising a mesh body woven integrally by a double needle bed high-speed warp knitting machine, the mesh body comprising a hollow jacquard layer 1, a hollow layer 2 woven under the hollow jacquard layer 1, and a hollow base layer 3 woven under the hollow layer 2.

[0062] The carved jacquard layer 1 includes a three-dimensional carved jacquard 11, which includes a plurality of coil structures 111 and a plurality of hollow holes 112. The coil structure 111 includes a plurality of first yarns 1111, and a plurality of the first yarns 1111 are cross-woven to form the coil structure 111. The coil structure 111 includes a looped coil structure 1112, a loose coil structure 1113, and an extended coil structure 1114. The hollow holes 112 are woven between the coil structures 111 and the coil structures 111.

[0063] The hollow jacquard layer 1 is a single-comb hollow jacquard layer 1.

[0064] The hollow layer 2 is woven between the hollow jacquard layer 1 and the hollow base layer 3 . The hollow layer 2 includes a plurality of second yarns 21 . The plurality of second yarns 21 are cross-woven to form the hollow layer 2 .

[0065] The carved layer 2 is woven between the carved jacquard layer 1 and the carved base layer 3, playing a role of connecting the upper and lower parts. Specifically, a part of the carved layer 2 is connected to the looped coil structure 1112 and the carved base layer 3, so that the mesh body does not delaminate and the structure is more stable; a part of the carved layer 2 is connected to the loose coil structure 1113 (because the carved jacquard process cannot complete the loose coils of the looped weaving) and the carved base layer 3, so that the loose coil structure 1113 is not affected by the tension and delaminated, and the shape retention is strong; a part of the carved layer 2 is connected to the extended coil structure 1114 (because the carved jacquard process cannot complete the coil extension line of the looped weaving) and the carved base layer 3, and the carved layer 2 pulls the extended coil structure 1114 downward, so that the structural stability of the mesh body is high.

[0066] The hollow base layer 3 is woven under the hollow layer 2, and the hollow base layer 3 includes a plurality of third yarns 31, and the plurality of third yarns 31 are cross-woven to form the hollow base layer 3, and a plurality of air-permeable tissues 32 are woven on the hollow base layer 3. The air-permeable tissue 32 can be a plain air-permeable tissue 32 or a gradient air-permeable tissue 32.

[0067] The denier of the first yarn 1111 is greater than the denier of the second yarn 21, and the denier of the first yarn 1111 is greater than the denier of the third yarn 31. The larger the denier of the first yarn 1111, the thicker the first yarn 1111 is, so that the three-dimensional carved jacquard 11 in the carved jacquard layer 1 has a stronger three-dimensional sense, a more prominent concavoconvex touch, and a more obvious concavoconvex visual sense.

[0068] The first yarn 1111 is one or a combination of colored yarn, luminous yarn, and reflective yarn. The colored yarn can be a mixed color linen low-elastic yarn or a space-dyed fantasy color low-elastic yarn, which is used to enrich the color of the three-dimensional carved jacquard 11; at the same time, it can be matched with luminous yarn and reflective yarn, and the luminous and reflective properties of the yarn can be used to make the mesh cloth clearly feel the luminous carving effect of the carved jacquard sandwich mesh cloth in a weak light environment.

[0069] The second yarn 21 is a transparent yarn or an elastic yarn. The transparent yarn can be transparent fish silk, TPU monofilament, TPEE monofilament or high-strength monofilament, which greatly enhances the transparent visual effect; the elastic yarn is used for weaving, so that the mesh has stronger extensibility.

[0070] The third yarn 31 is one or a combination of two or more of colored yarn, transparent yarn, and elastic yarn.

[0071] The number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21. Since the number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21, the texture of the carved jacquard layer 1 and the carved base layer 3 is softer, making the overall hand feel of the mesh cloth softer.

[0072] Reference Figure 2-3 , Figure 2 This is a first physical front view of the sandwich mesh with three-dimensional carved jacquard of the present invention; Figure 3 This is the first real back view of the sandwich mesh with three-dimensional carved jacquard of the present invention.

[0073] The mesh body is woven integrally by a double-needle-bed high-speed warp knitting machine, and the mesh body includes a hollow jacquard layer 1, a hollow jacquard layer 2 and a hollow base layer 3. The three-dimensional hollow jacquard 11 is woven by changing the yarn threading of the comb bar and the local missed needle process, so that the mesh has good air permeability, wrinkle resistance, shape retention, strong 3D stereoscopic sense, and strong hollow effect, which breaks through the technical difficulties of the prior art mesh that has poor air permeability, no obvious concave-convex touch and visual sense, only has a concave-convex relief effect, and does not have a hollow effect.

[0074] Reference Figure 8 , Figure 8 The present invention is a process flow chart of a method for manufacturing a sandwich mesh with three-dimensional carved jacquard.

[0075] This embodiment also provides a method for making the sandwich mesh with the three-dimensional carved jacquard 11 as described above, comprising the following steps:

[0076] S1. Comb setting

[0077] A double needle bed high-speed warp knitting machine is selected for knitting. The double needle bed high-speed warp knitting machine has at least 4 comb bars. The 4 comb bars are sequentially provided with a ground comb bar GB1, a ground comb bar GB2, a ground comb bar GB3, and a ground comb bar GB4 from the front needle bed to the rear needle bed.

[0078] S2. Warping

[0079] Ground combing bar GB1 warps P-FDY150D / 36F semi-bright yarn / P-FDY75D / 36F semi-bright yarn (i.e., the first yarn 1111) with 6 warps, each with 317 yarns, and the content of P-FDY150D / 36F semi-bright yarn / P-FDY75D / 36F semi-bright yarn accounts for 28%-36%;

[0080] Ground combing bar GB2 warps P-DT30D / 1F semi-bright yarn (i.e., the second yarn 21) with 6 warps, each with 474 yarns, and P-DT30D / 1F semi-bright content accounts for 12%-22%;

[0081] Ground combing bar GB3 warping P-DTY150D / 48F semi-gloss white low-elastic light mesh yarn (i.e. the third yarn 31) has 6 warps, each with 238 yarns, and the content of P-DTY150D / 48F semi-gloss white low-elastic light mesh accounts for 20%-28%;

[0082] The ground comb bar GB4 warps P-DTY150D / 48F semi-gloss white low-elastic light mesh yarn (ie the third yarn 31) with 6 warps, each with 238 yarns, and the content of P-DTY150D / 48F semi-gloss white low-elastic light mesh accounts for 20%-28%.

[0083] S3. Yarn threading

[0084] The ground bar GB1 is used for threading on the double-needle-bed high-speed warp knitting machine in a four-thread and two-hole manner;

[0085] The ground bar GB2 is used for threading the yarn on the double needle bed high-speed warp knitting machine in a full threading manner;

[0086] The ground bar GB3 is used for threading yarn on a double-needle-bed high-speed warp knitting machine in a one-thread-one-empty manner;

[0087] The ground bar GB4 is used for threading yarn on a double-needle-bed high-speed warp knitting machine in a one-thread-one-empty manner;

[0088] The warp let-off amount of the gear corresponding to the ground comb bar GB1 is 1600-2800mm / lac;

[0089] The warp let-off amount of the gear corresponding to the ground comb bar GB2 is 6800-8000mm / lac; the warp let-off amount of the gear corresponding to the ground comb bar GB3 is 2400-3600mm / lac;

[0090] The warp feed rate of the gear corresponding to the ground comb bar GB4 is 2400-3600mm / lac.

[0091] S4. Weaving

[0092] Reference Fig. 9 , Fig. 9 Yarn lapping movement in the method for making sandwich mesh with three-dimensional carved jacquard of the present invention Figure 1 The ground bar GB1 lays yarn on the front needle bed and runs a warp satin weave.

[0093] 3-2 / 3-4 / 1-0 / 3-4 / 3-2 / 4-5 / 6-7 / 6-5 / 8-9 / 6-5 / 6-7 / 5-4 / / form the carved jacquard layer 1,

[0094] The ground comb bar GB2 alternately lays yarn on the front needle bed and the rear needle bed in turn and runs a changed warp knitting structure 1-0 / 2-1 / 2-3 / 1-2 / / to form the carved layer 2. Specifically, the ground comb bar GB2 runs a warp knitting warp pile structure 1-0 / 2-3 / / on the front needle bed (that is, the carved layer 2 is on the carved jacquard layer 1) to perform loop knitting; the ground comb bar GB2 runs a warp knitting chain structure 2-1 / 1-2 / / on the rear needle bed (that is, the carved layer 2 is on the carved base layer 3) to perform loop knitting;

[0095] The ground comb bar GB3 lays yarn on the rear needle bed and runs 5 stitches of plain warp stitch 0-1 / 5-4 / / to form the carved base layer 3, and the ground comb bar GB4 lays yarn on the rear needle bed and runs 5 stitches of plain warp stitch 5-4 / 0-1 / / to form the carved base layer 3.

[0096] Among them, in the threading step, the ground comb bar GB1 uses two yarns to make one yarn to thread the yarn. By threading the yarn with two yarns as one yarn, the D number of the yarn is increased, and the concave and convex touch and visual sense of the engraving effect are enhanced.

[0097] This embodiment uses a double-needle-bed high-speed warp knitting machine to weave a sandwich mesh, and utilizes the yarn threading changes of the comb bar and the local missed needle process to weave a three-dimensional hollow jacquard 11, so that the mesh has good air permeability, wrinkle resistance, and shape retention, a strong 3D stereoscopic sense, and a strong hollowing effect, which breaks through the technical difficulties of the prior art mesh having poor air permeability, no obvious concave-convex tactile and visual sense, only a concave-convex relief effect, and no hollowing effect.

[0098] In this embodiment, the comb bar for weaving the hollow layer 2 is also arranged to adopt a double needle bed process, and the yarn is alternately laid in the front needle bed and the rear needle bed to form loops for weaving, so that the structure of the sandwich mesh is more stable.

[0099] In this embodiment, the comb bar for weaving the openwork jacquard layer 1 uses two yarns and one yarn to thread the yarn, thereby increasing the D number of the yarn and enhancing the concave and convex touch and visual sense of the openwork effect.

[0100] The manufacturing method of this embodiment is simple, and the three-dimensional carved jacquard 11 is woven by using the yarn threading changes of the comb and the local dropped stitch process, so that the sandwich mesh has a strong 3D stereoscopic sense, a strong carving effect, and a more prominent concave and convex sense, which greatly enhances the tactile and visual sense of the concave and convex.

Specifically, a part of the carved layer 2 is connected to the looped coil structure 1112 and the carved base layer 3, so that the mesh body does not delaminate and the structure is more stable; a part of the carved layer 2 is connected to the loose coil structure 1113 (because the carved jacquard process cannot complete the loose coils of the looped weaving) and the carved base layer 3, so that the loose coil structure 1113 is not affected by the tension and delaminated, and the shape retention is strong; a part of the carved layer 2 is connected to the extended coil structure 1114 (because the carved jacquard process cannot complete the coil extension line of the looped weaving) and the carved base layer 3, and the carved layer 2 pulls the extended coil structure 1114 downward, so that the structural stability of the mesh body is high.

[0108] The hollow base layer 3 is woven under the hollow layer 2, and the hollow base layer 3 includes a plurality of third yarns 31, and the plurality of third yarns 31 are cross-woven to form the hollow base layer 3, and a plurality of air-permeable tissues 32 are woven on the hollow base layer 3. The air-permeable tissue 32 can be a plain air-permeable tissue 32 or a gradient air-permeable tissue 32.

[0109] The denier of the first yarn 1111 is greater than the denier of the second yarn 21, and the denier of the first yarn 1111 is greater than the denier of the third yarn 31. The larger the denier of the first yarn 1111, the thicker the first yarn 1111 is, so that the three-dimensional carved jacquard 11 in the carved jacquard layer 1 has a stronger three-dimensional sense, a more prominent concavoconvex touch, and a more obvious concavoconvex visual sense.

[0110] The first yarn 1111 is one or a combination of colored yarn, luminous yarn, and reflective yarn. The colored yarn can be a mixed color linen low-elastic yarn or a space-dyed fantasy color low-elastic yarn, which is used to enrich the color of the three-dimensional carved jacquard 11; at the same time, it can be matched with luminous yarn and reflective yarn, and the luminous and reflective properties of the yarn can be used to make the mesh cloth clearly feel the luminous carving effect of the carved jacquard sandwich mesh cloth in a weak light environment.

[0111] The second yarn 21 is a transparent yarn or an elastic yarn. The transparent yarn can be transparent fish silk, TPU monofilament, TPEE monofilament or high-strength monofilament, which greatly enhances the transparent visual effect; the elastic yarn is used for weaving, so that the mesh has stronger extensibility.

[0112] The third yarn 31 is one or a combination of two or more of colored yarn, transparent yarn, and elastic yarn.

[0113] The number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21. Since the number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21, the texture of the carved jacquard layer 1 and the carved base layer 3 is softer, making the overall hand feel of the mesh cloth softer.

[0115] The mesh body is woven integrally by a double-needle-bed high-speed warp knitting machine, and the mesh body includes a hollow jacquard layer 1, a hollow jacquard layer 2 and a hollow base layer 3. The three-dimensional hollow jacquard 11 is woven by changing the yarn threading of the comb bar and the local missed needle process, so that the mesh has good air permeability, wrinkle resistance, shape retention, strong 3D stereoscopic sense, and strong hollow effect, which breaks through the technical difficulties of the prior art mesh that has poor air permeability, no obvious concave-convex touch and visual sense, only has a concave-convex relief effect, and does not have a hollow effect.

[0126] S3. Yarn threading

[0127] The ground bar GB1 is used for threading the yarn on the double needle bed high-speed warp knitting machine in a three-thread and three-hole manner;

[0139] The ground bar GB1 lays yarn on the front needle bed and runs a variable warp satin structure.

[0140] 5-6 / 5-4 / 6-7 / 5-4 / 5-6 / 4-3 / 2-1 / 2-3 / 1-0 / 2-3 / 2-1 / 3-4 / / form the carved jacquard layer 1,

[0141] The ground bar GB2 lays yarn on the front needle bed and runs a variable warp satin structure.

[0142] 2-1 / 2-3 / 1-0 / 2-3 / 2-1 / 3-4 / 5-6 / 5-4 / 6-7 / 5-4 / 5-6 / 4-3 / / form the carved jacquard layer 1,

[0143] The ground comb bar GB3 alternately lays yarn on the front needle bed and the rear needle bed in turn and runs a changed warp knitting structure 1-0 / 2-1 / 2-3 / 1-2 / / to form the carved layer 2. Specifically, the ground comb bar GB3 runs a warp knitting warp pile structure 1-0 / 2-3 / / on the front needle bed (that is, the carved layer 2 is on the carved jacquard layer 1) to perform loop knitting; the ground comb bar GB3 runs a warp knitting chain structure 2-1 / 1-2 / / on the rear needle bed (that is, the carved layer 2 is on the carved base layer 3) to perform loop knitting;

[0144] The ground comb bar GB4 lays yarn on the rear needle bed and runs 5 stitches of plain warp stitch 0-1 / 5-4 / / to form the carved base layer 3, and the ground comb bar GB5 lays yarn on the rear needle bed and runs 5 stitches of plain warp stitch 5-4 / 0-1 / / to form the carved base layer 3.

[0145] Among them, in the threading step, the ground combing bar GB1 and the ground combing bar GB2 both use two yarns and one yarn to thread the yarn. By threading the yarn with two yarns and one yarn, the D number of the yarn is increased, and the concave and convex touch and visual sense of the engraving effect are enhanced.

[0146] This embodiment uses a double-needle-bed high-speed warp knitting machine to weave a sandwich mesh, and utilizes the yarn threading changes of the comb bar and the local missed needle process to weave a three-dimensional hollow jacquard 11, so that the mesh has good air permeability, wrinkle resistance, and shape retention, a strong 3D stereoscopic sense, and a strong hollowing effect, which breaks through the technical difficulties of the prior art mesh having poor air permeability, no obvious concave-convex tactile and visual sense, only a concave-convex relief effect, and no hollowing effect.

[0147] In this embodiment, the comb bar for weaving the hollow layer 2 is also arranged to adopt a double needle bed process, and the yarn is alternately laid in the front needle bed and the rear needle bed to form loops for weaving, so that the structure of the sandwich mesh is more stable.

[0148] In this embodiment, the comb bar for weaving the openwork jacquard layer 1 uses two yarns and one yarn to thread the yarn, thereby increasing the D number of the yarn and enhancing the concave and convex touch and visual sense of the openwork effect.

[0149] The manufacturing method of this embodiment is simple, and the three-dimensional carved jacquard 11 is woven by using the yarn threading changes of the comb and the local dropped stitch process, so that the sandwich mesh has a strong 3D stereoscopic sense, a strong carving effect, and a more prominent concave and convex sense, which greatly enhances the tactile and visual sense of the concave and convex.

[0150] Example 3

[0151] Reference Figure 1 , Figure 1It is a cross-sectional view of the sandwich mesh with three-dimensional carved jacquard of the present invention.

[0152] The present embodiment provides a sandwich mesh with a three-dimensional hollow jacquard 11, comprising a mesh body woven integrally by a double needle bed high-speed warp knitting machine, the mesh body comprising a hollow jacquard layer 1, a hollow layer 2 woven under the hollow jacquard layer 1, and a hollow base layer 3 woven under the hollow layer 2.

[0153] The carved jacquard layer 1 includes a three-dimensional carved jacquard 11, which includes a plurality of coil structures 111 and a plurality of hollow holes 112. The coil structure 111 includes a plurality of first yarns 1111, and a plurality of the first yarns 1111 are cross-woven to form the coil structure 111. The coil structure 111 includes a looped coil structure 1112, a loose coil structure 1113, and an extended coil structure 1114. The hollow holes 112 are woven between the coil structures 111 and the coil structures 111.

[0154] The hollow jacquard layer 1 is a multi-comb hollow jacquard layer 1.

Specifically, a part of the carved layer 2 is connected to the looped coil structure 1112 and the carved base layer 3, so that the mesh body does not delaminate and the structure is more stable; a part of the carved layer 2 is connected to the loose coil structure 1113 (because the carved jacquard process cannot complete the loose coils of the looped weaving) and the carved base layer 3, so that the loose coil structure 1113 is not affected by the tension and delaminated, and the shape retention is strong; a part of the carved layer 2 is connected to the extended coil structure 1114 (because the carved jacquard process cannot complete the coil extension line of the looped weaving) and the carved base layer 3, and the carved layer 2 pulls the extended coil structure 1114 downward, so that the structural stability of the mesh body is high.

[0157] The hollow base layer 3 is woven under the hollow layer 2, and the hollow base layer 3 includes a plurality of third yarns 31, and the plurality of third yarns 31 are cross-woven to form the hollow base layer 3, and a plurality of air-permeable tissues 32 are woven on the hollow base layer 3. The air-permeable tissue 32 can be a plain air-permeable tissue 32 or a gradient air-permeable tissue 32.

[0158] The denier of the first yarn 1111 is greater than the denier of the second yarn 21, and the denier of the first yarn 1111 is greater than the denier of the third yarn 31. The larger the denier of the first yarn 1111, the thicker the first yarn 1111 is, so that the three-dimensional carved jacquard 11 in the carved jacquard layer 1 has a stronger three-dimensional sense, a more prominent concavoconvex touch, and a more obvious concavoconvex visual sense.

[0159] The first yarn 1111 is one or a combination of colored yarn, luminous yarn, and reflective yarn. The colored yarn can be a mixed color linen low-elastic yarn or a space-dyed fantasy color low-elastic yarn, which is used to enrich the color of the three-dimensional carved jacquard 11; at the same time, it can be matched with luminous yarn and reflective yarn, and the luminous and reflective properties of the yarn can be used to make the mesh cloth clearly feel the luminous carving effect of the carved jacquard sandwich mesh cloth in a weak light environment.

[0160] The second yarn 21 is a transparent yarn or an elastic yarn. The transparent yarn can be transparent fish silk, TPU monofilament, TPEE monofilament or high-strength monofilament, which greatly enhances the transparent visual effect; the elastic yarn is used for weaving, so that the mesh has stronger extensibility.

[0161] The third yarn 31 is one or a combination of two or more of colored yarn, transparent yarn, and elastic yarn.

[0162] The number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21. Since the number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21, the texture of the carved jacquard layer 1 and the carved base layer 3 is softer, making the overall hand feel of the mesh cloth softer.

[0214] The number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21. Since the number of spinnerets (F number) of the first yarn 1111 and the third yarn 31 is greater than the number of spinnerets (F number) of the second yarn 21, the texture of the carved jacquard layer 1 and the carved base layer 3 is softer, making the overall hand feel of the mesh cloth softer.

[0216] The mesh body is woven integrally by a double-needle-bed high-speed jacquard machine, and the mesh body includes an openwork jacquard layer 1, an openwork layer 2 and an openwork base layer 3. The three-dimensional openwork jacquard 11 is woven by utilizing the yarn threading changes of the comb bar and the local missed needle process, so that the mesh has good air permeability, wrinkle resistance, shape retention, strong 3D stereoscopic sense, and strong openwork effect, which breaks through the technical difficulties of the prior art mesh, such as poor air permeability, no obvious concave-convex touch and visual sense, only concave-convex relief effect, and no openwork effect.

[0244] S4. Weaving

[0245] Reference Fig.11 , Fig.11Yarn lapping movement in the method for making sandwich mesh with three-dimensional carved jacquard of the present invention Figure 3 .

[0246] The jacquard bar JB1 lays yarn on the front needle bed and runs a variable warp satin weave 0-1 / 1-1 / 2-1 / 0-0 / / to form the carved jacquard layer 1;

[0247] The jacquard bar JB2 lays yarn on the front needle bed and runs a variable warp satin weave 0-1 / 1-1 / 2-1 / 0-0 / / to form the carved jacquard layer 1;

[0248] The jacquard bar JB3 lays yarn on the front needle bed and runs a warp satin weave of 1-1 / 1-0 / 1-1 / 1-2 / / to form the carved jacquard layer 1;

[0249] The jacquard bar JB4 lays yarn on the front needle bed and runs a variable warp satin weave 1-1 / 1-0 / 1-1 / 1-2 / / to form the carved jacquard layer 1;

[0250] The ground comb bar GB5 alternately lays yarn on the front needle bed and the rear needle bed in turn and runs a changed warp knitting structure 1-0 / 2-1 / 2-3 / 1-2 / / to form the carved layer 2. Specifically, the ground comb bar GB4 runs a warp knitting warp pile structure 1-0 / 2-3 / / on the front needle bed (that is, the carved layer 2 is on the carved jacquard layer 1) to perform loop knitting; the ground comb bar GB4 runs a warp knitting chain structure 2-1 / 1-2 / / on the rear needle bed (that is, the carved layer 2 is on the carved base layer 3) to perform loop knitting;

[0251] The ground combing bar GB6 lays yarn on the rear needle bed and runs the warp knitting structure 1-0 / 0-1 / 1-2 / 2-1 / / to form the carved base layer 3;

[0252] The ground comb bar GB7 lays yarn on the rear needle bed and passes through the diagonal weave 3-4 / 1-0 / / to form the carved base layer 3.

[0253] Among them, in the threading step, the jacquard comb JB1, the jacquard comb JB2, the jacquard comb JB3, and the jacquard comb JB4 all use needle method changes to overlap the coil extension lines, thereby enhancing the concave and convex touch and visual sense of the carving effect.

[0254] This embodiment uses a double-needle-bed high-speed jacquard machine to weave a sandwich mesh, and utilizes the yarn threading changes of the comb and the local missed needle process to weave a three-dimensional carved jacquard 11, so that the mesh has good air permeability, wrinkle resistance, and shape retention, a strong 3D stereoscopic sense, and a strong carving effect, which breaks through the technical difficulties of the prior art mesh having poor air permeability, no obvious concave-convex tactile and visual sense, only a concave-convex relief effect, and no carving effect.

[0255] In this embodiment, the comb bar for weaving the hollow layer 2 is also arranged to adopt a double needle bed process, and the yarn is alternately laid in the front needle bed and the rear needle bed to form loops for weaving, so that the structure of the sandwich mesh is more stable.

[0256] In this embodiment, the comb bar for weaving the openwork jacquard layer 1 uses two yarns and one yarn to thread the yarn, thereby increasing the D number of the yarn and enhancing the concave and convex touch and visual sense of the openwork effect.

[0257] The manufacturing method of this embodiment is simple, and the three-dimensional carved jacquard 11 is woven by using the yarn threading changes of the comb and the local dropped stitch process, so that the sandwich mesh has a strong 3D stereoscopic sense, a strong carving effect, and a more prominent concave and convex sense, which greatly enhances the tactile and visual sense of the concave and convex.

[0258] In summary, the embodiment uses a jacquard comb for engraving jacquard, so that the mesh has good air permeability, wrinkle resistance, shape retention, strong 3D stereoscopic sense, and strong engraving effect, which breaks through the technical difficulties of the prior art mesh with poor air permeability, no obvious concave and convex touch and visual sense, only concave and convex relief effect, and no engraving effect. In Example 2-3, multiple combs are used for engraving jacquard, and while the mesh has good air permeability, wrinkle resistance, and shape retention, its 3D stereoscopic sense is stronger, the concave and convex touch and visual sense are more prominent and clear, and the engraving effect is stronger.

[0259] Embodiments 1-3 are knitted in one piece using a double needle bed high-speed warp knitting machine, and the three-dimensional carved jacquard 11 is knitted by using the yarn insertion change of the comb bar and the local drop stitch process, so that the sandwich mesh has a strong 3D stereoscopic sense, a strong carving effect, and a more prominent concave and convex sense, which greatly enhances the tactile and visual sense of the concave and convex. Embodiment 4 is knitted in one piece using a double needle bed high-speed jacquard machine, and the three-dimensional carved jacquard 11 is knitted with more distinctive features by using the yarn insertion change of the comb bar and the local drop stitch process, so that the sandwich mesh has a stronger 3D stereoscopic sense, a stronger carving effect, and a more prominent concave and convex sense, which greatly enhances the tactile and visual sense of the concave and convex.
