Technical Field

[0001] The invention relates to the technical field of mesh cloth, in particular to a sandwich mesh cloth with floating yarn 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 mesh fabrics. Therefore, sandwich mesh fabrics with jacquard effects have appeared on the market.

[0004] The jacquard on the sandwich mesh on the market is woven on the surface of the sandwich mesh, and the jacquard is woven as a whole with the sandwich mesh, which lacks a sense of elegance, has poor air permeability, and the mesh feels hard. Summary of the invention

[0005] 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.

[0006] The object of the present invention is to overcome the above-mentioned shortcomings and provide a sandwich mesh with floating yarn 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 comprises a surface layer, a middle layer, a bottom layer and a floating yarn jacquard layer. The floating yarn jacquard is produced by utilizing the yarn threading changes of the comb bar, the characteristics of the lack-pad tissue and the unique negative warp feeding method of the yarn frame, so that the jacquard on the mesh has a floating feeling and is not messy, thereby making the mesh have good air permeability, wrinkle resistance, shape retention and wear resistance.

[0007] To achieve the above purpose, the technical solution of the present invention is: a sandwich mesh with floating yarn jacquard, including a mesh body woven integrally by a double needle bed high-speed warp knitting machine, the mesh body including a surface layer, a bottom layer, a middle layer and a floating yarn jacquard layer. The surface layer includes multiple first yarns, and multiple first yarns are cross-woven to form the surface layer; the bottom layer is woven below the surface layer, and the bottom layer includes multiple second yarns, and multiple second yarns are cross-woven to form the bottom layer; the middle layer is woven between the surface layer and the bottom layer and is used to connect the surface layer and the bottom layer, and the middle layer includes multiple third yarns, and multiple third yarns are cross-woven to form the middle layer; the floating yarn jacquard layer is woven on the surface layer and includes a floating yarn jacquard area and a plain jacquard area, the floating yarn jacquard layer includes multiple fourth yarns, multiple fourth yarns and multiple first yarns are cross-woven to form the plain jacquard area, multiple fourth yarns are separately woven from multiple first yarns to form the floating yarn jacquard area, and multiple fourth yarns in the floating yarn jacquard area are separately woven to form the first floating yarn jacquard area. The present invention achieves the advantages of separate weaving of multiple fourth yarns and multiple first yarns, and separate weaving of multiple fourth yarns, that is, each coil longitudinally is formed by the same warp yarn, each warp yarn is always on the same needle during weaving, and the longitudinal rows are not connected to each other. The present invention also utilizes the characteristics of the missing pad structure that no padding is done before the needle hook in some horizontal rows but only swings between the needles, and the characteristics of no padding in some horizontal rows that no padding is done before the needle hook but only swings between the needles, combined with the change of the empty threading of the comb and the unique negative warp feeding method of the yarn frame to weave a sandwich mesh with floating yarns between two vertical strips.

[0008] Preferably, the floating yarn jacquard layer further comprises a plurality of fifth yarns, the plurality of fifth yarns are cross-woven with the plurality of first yarns and the plurality of fourth yarns in the plain jacquard region, and the plurality of fifth yarns are separately woven with the plurality of first yarns and the plurality of fourth yarns in the floating yarn jacquard region to form a second floating yarn jacquard region.

[0009] Preferably, the floating yarn jacquard layer also includes a plurality of sixth yarns, and the plurality of the sixth yarns are cross-woven with the plurality of the first yarns and the plurality of the fourth yarns in the plain jacquard area. The plurality of the sixth yarns are separated from the plurality of the first yarns in the floating yarn jacquard area and cross-woven with the plurality of the fourth yarns to form a third floating yarn jacquard area with mesh holes. The present invention cross-weaves the sixth yarn with the fourth yarn, so that the fourth yarn, which is originally unconnected, is extended to the left and right directions to form a floating yarn jacquard with mesh holes under the action of the sixth yarn and the first yarn, that is, the oblique lack of pad weaving is performed by using the empty yarn passing through the comb and the unique negative warp feeding method of the yarn rack. The longitudinal rows are not connected to each other and will be affected by the tension of the mesh cloth itself, and extend to the left and right directions to form mesh holes. The lack of pad part does not do the front pad yarn of the needle hook in some horizontal rows but only swings between the needles, which will be affected by the tension of the mesh cloth mesh to form a hole center line effect.

[0010] Preferably, the first yarn is a transparent yarn, which can be transparent fish silk, TPU monofilament, TPEE monofilament, or high-strength monofilament, which can not only enhance the transparent visual effect, but also make the mesh slightly elastic when it is woven, thereby enhancing the extensibility of the mesh.

[0180] This embodiment also provides a method for making the sandwich mesh with floating yarn jacquard as described above, comprising the following steps:

[0181] S1. Comb setting

[0182] A double-needle-bed high-speed jacquard machine is used for knitting. The double-needle-bed high-speed jacquard machine has at least 5 comb bars. The 5 comb bars are sequentially provided with a ground comb bar GB1, a jacquard comb bar JK1-1, a jacquard comb bar JK1-2, a ground comb bar GB4, and a ground comb bar GB5 from the front needle bed to the rear needle bed;

[0183] S2. Warping

[0184] The ground comb bar GB1 warps P-FDY100D / 48F semi-bright yarn (i.e., the first yarn) with 6 warps, each with 512 yarns, and the P-FDY100D / 48F semi-bright content accounts for 5% to 17%.

[0189] S3. Yarn threading

[0190] The ground comb bar GB1 is threaded on the double needle bed high-speed jacquard machine in a full threading manner, and the warp feed amount of the gear corresponding to the ground comb bar GB1 is 1200-2200 mm / lac.

[0191] The jacquard bar JK1-1 is used for threading yarn on a double-needle-bed high-speed jacquard machine in a one-through-one-empty manner. The corresponding gear warp feed amount of the jacquard bar JK1-1 is 1700 to 2700 mm / lac.

[0192] The jacquard bar JK1-2 is used for threading yarn on a double-needle-bed high-speed jacquard machine in a one-through-one-empty manner. The corresponding gear warp feed amount of the jacquard bar JK1-2 is 1700 to 2700 mm / lac.

[0194] The ground comb bar GB5 is threaded on the double needle bed high-speed jacquard machine in a full threading manner, and the warp feed amount of the gear corresponding to the ground comb bar GB5 is 1600-2600mm / lac.

[0195] S4. Weaving

[0196] The ground comb bar GB1 uses the double needle bed process 0-0 / 0-1 / 1-1 / 1-0 / / , alternately pads yarn into loops on the front needle bed and the rear needle bed, uses the chain stitch structure 0-1 / 1-0 / / on the front needle bed, and uses the weft insertion structure 0-0 / 1-1 / / on the rear needle bed to form the surface layer 1.

[0197] The jacquard bar JK1-1 and the jacquard bar JK1-2 pad yarn on the front needle bed and use the changed jacquard structure to form the floating yarn jacquard layer 4. The jacquard bar JK1-1 uses the jacquard basic structure 1-0 / 0-0 / 0-1 / 0-1 / / , and the jacquard bar JK1-2 uses the jacquard basic structure 1-0 / 0-0 / 0-1 / 0-1 / / . The jacquard bar JK1-1 and the jacquard bar JK1-2 are combined with the needle method change so that some parts use the warp knitting missing pad structure 1-1 / 1-1 / / on the front needle bed, and some parts use the warp knitting warp plain structure 1-0 / 1-2 / 1-1 / 1-1 / / .

[0198] The ground comb bar GB4 uses the double needle bed process 1-0 / 1-0 / 0-1 / 0-1 / / , alternately pads yarn on the front needle bed and the rear needle bed to form loops, uses the warp knitting chain structure 1-0 / 0-1 / / to weave loops on the rear needle bed, and uses the warp knitting chain structure 1-0 / 0-1 / / to weave loops on the front needle bed.

[0199] The ground comb bar GB5 uses the double needle bed process 1-0 / 2-2 / 2-3 / 1-1 / / , alternately pads yarn on the front needle bed and the rear needle bed to form loops, uses the warp knitting weft insertion structure 2-2 / 1-1 / / on the front needle bed to carry out weft insertion knitting, and uses the warp knitting warp pile structure 1-0 / 2-3 / / on the rear needle bed to carry out loop knitting.

[0200] In this weaving step, the ground comb bar GB1 follows the weft insertion structure 0-0 / 1-1 / / on the rear needle bed. In this process, there is no comb bar on the rear needle bed to pull and fix it. It will be affected by the tension and will not participate in weaving. It is only used to increase the lateral movement time of the comb bar and play a transitional role.

[0201] In the warping step, the warp feeding mode of the jacquard combs JK1-1 and the jacquard combs JK1-2 is the creel passive warp feeding, and the warp feeding mode of the ground combs GB1, the ground combs GB4 and the ground combs GB5 is the head active warp feeding.

[0202] The creel uses negative warp feeding, and the yarn is independently fed through the bobbin above the creel. Each yarn is wound on a 23cm long inner warp tube. The front section of the tube is equipped with a row of aluminum strips and a ring-type pressure tensioner. The creel uses negative warp feeding. Through the creel's negative warp feeding method, the tension of each yarn can be accurately controlled, making the tension adjustment of the jacquard comb more flexible, which helps to enrich the jacquard comb's jacquard effect. If the disc head positive warp feeding is used: the tension control of the jacquard comb is uniformly fed by the warp beam, which means that the tension of the jacquard comb is limited, and the jacquard jacquard effect becomes too limited, which is not conducive to the innovation of jacquard products.

[0203] The warp beam positively feeds the warp yarn uniformly through the warp beams in front and behind the jacquard machine. Through the positive warp beam feeding, a higher machine speed can be achieved, which improves production efficiency; changing the warp feeding amount is convenient and quick, and there is no need to change the warp feeding gear; when changing the warp beam, there is no need to manually turn the warp beam, just a simple button is needed.

[0204] This embodiment uses a double-needle-bed high-speed jacquard machine for weaving. The warp knitting chain structure of the ground comb bar GB1 and the changed needle structure of the jacquard bar JK1-1 and the jacquard bar JK1-2 utilize the changes in the empty threading of the comb bar and the unique negative warp feeding method of the creel to weave a unique jacquard mesh with floating yarns between two vertical stripes. The vertical stripe part of the ground comb bar GB1 utilizes the characteristics that each coil is formed by the same warp yarn in the longitudinal direction. During weaving, each warp yarn is always on the same needle, and the longitudinal rows are not connected to each other. The floating yarn part of the jacquard bar JK1-1 and the jacquard bar JK1-2 utilizes the characteristics of the missing pad structure that does not do the yarn in front of the needle hook in some horizontal rows but only swings between the needles, thereby forming the first floating yarn jacquard area 411.

[0213] The floating yarn jacquard layer 4 also includes multiple fifth yarns, which are cross-woven with multiple first yarns and multiple fourth yarns in the plain jacquard area 42, and are separately woven with multiple first yarns and multiple fourth yarns in the floating yarn jacquard area 41 to form a second floating yarn jacquard area 412.

[0214] The first yarn is a transparent yarn, which can be transparent fish silk, TPU monofilament, TPEE monofilament, or high-strength monofilament, which can not only enhance the transparent visual effect, but also make the mesh cloth slightly elastic when it is woven, thereby enhancing the extensibility of the mesh cloth.

[0215] The fourth yarn and the fifth yarn are both colored yarns, and the color of the fifth yarn is inconsistent with the color of the fourth yarn. The colored yarn can be mixed color linen low-elastic yarn, space-dyed fantasy color low-elastic yarn, seven-color silk, luminous yarn, reflective yarn, and the properties of colored yarn are used to enrich the color effect of floating yarn and design new functional mesh fabrics.

[0216] The surface layer 1 has a plurality of air holes 11. By increasing the air holes 11, the air permeability of the mesh is greatly enhanced.

[0217] In this embodiment, multiple fourth yarns are woven separately from multiple first yarns, and multiple fourth yarns are also woven separately, that is, each coil is formed by the same warp yarn, each warp yarn is always on the same needle during weaving, and the longitudinal rows are not connected with each other. The lack of padding structure is used, and the yarn is not padded before the needle hook in some horizontal rows but only swings between the needles. Combined with the change of the empty threading of the comb and the unique negative warp feeding method of the creel, a sandwich mesh cloth with floating yarns between two vertical strips is formed.

[0218] In this embodiment, the fifth yarn is added to make the floating yarn jacquard richer, more flowing and more beautiful.

[0239] S4. Weaving

[0240] The ground comb bar GB1 uses the double needle bed process 0-0 / 0-1 / 1-1 / 1-0 / / , alternately pads yarn into loops on the front needle bed and the rear needle bed, uses the chain stitch structure 0-1 / 1-0 / / on the front needle bed, and uses the weft insertion structure 0-0 / 1-1 / / on the rear needle bed to form the surface layer 1.

[0241] The jacquard bars JK1-1 and JK1-2 pad yarn on the front needle bed and use the changed jacquard structure, and the jacquard bars JK2-1 and JK2-2 pad yarn on the front needle bed and use the changed jacquard structure to form the floating yarn jacquard layer 4.

[0242] The jacquard bar JK1-1 uses the jacquard basic structure 1-0 / 0-0 / 0-1 / 0-1 / / , the jacquard bar JK1-2 uses the jacquard basic structure 1-0 / 0-0 / 0-1 / 0-1 / / , the jacquard bar JK1-1 and the jacquard bar JK1-2 are combined with the change of needle method so that some parts on the front needle bed use the warp knitted missing pad structure 1-1 / 1-1 / / , and some parts use the warp knitted plain structure 1-0 / 1-2 / 1-1 / 1-1 / / .

[0243] The jacquard bar JK2-1 uses the jacquard basic structure 1-0 / 1-0 / 1-2 / 1-2 / / , the jacquard bar JK2-2 uses the jacquard basic structure 1-0 / 1-0 / 1-2 / 1-2 / / , the jacquard bar JK2-1 and the jacquard bar JK2-2 are combined with the change of needle method so that some parts use the warp pile structure 1-0 / 2-3 / / on the front needle bed, and some parts use the warp knitting plain structure 1-0 / 1-2 / / , 2-1 / 2-3 / / on the front needle bed.

[0244] The ground comb bar GB6 uses the double needle bed process 1-0 / 1-0 / 0-1 / 0-1 / / , alternately pads yarn on the front needle bed and the rear needle bed to form loops, uses the warp knitting chain structure 1-0 / 0-1 / / to weave loops on the rear needle bed, and uses the warp knitting chain structure 1-0 / 0-1 / / to weave loops on the front needle bed.

[0245] The ground comb bar GB57 uses the double needle bed process 1-0 / 2-2 / 2-3 / 1-1 / / , and the front needle bed and the rear needle bed are alternately used for yarn padding and looping. The front needle bed uses the warp knitting weft insertion structure 2-2 / 1-1 / / for weft insertion weaving, and the rear needle bed uses the warp knitting warp pile structure 1-0 / 2-3 / / for looping weaving.

[0246] In this weaving step, the ground comb bar GB1 follows the weft insertion structure 0-0 / 1-1 / / on the rear needle bed. In this process, there is no comb bar on the rear needle bed to pull and fix it. It will be affected by the tension and will not participate in weaving. It is only used to increase the lateral movement time of the comb bar and play a transitional role.

[0247] In the warping step, the warp feeding mode of the jacquard combs JK1-1 and the jacquard combs JK1-2 is the creel passive warp feeding, and the warp feeding mode of the ground combs GB1, the ground combs GB4 and the ground combs GB5 is the head active warp feeding.

[0248] The creel uses negative warp feeding, and the yarn is independently fed through the bobbin above the creel. Each yarn is wound on a 23cm long inner warp tube. The front section of the tube is equipped with a row of aluminum strips and a ring-type pressure tensioner. The creel uses negative warp feeding. Through the creel's negative warp feeding method, the tension of each yarn can be accurately controlled, making the tension adjustment of the jacquard comb more flexible, which helps to enrich the jacquard comb's jacquard effect. If the disc head positive warp feeding is used: the tension control of the jacquard comb is uniformly fed by the warp beam, which means that the tension of the jacquard comb is limited, and the jacquard jacquard effect becomes too limited, which is not conducive to the innovation of jacquard products.

[0249] The warp beam positively feeds the warp yarn uniformly through the warp beams in front and behind the jacquard machine. Through the positive warp beam feeding, a higher machine speed can be achieved, which improves production efficiency; changing the warp feeding amount is convenient and quick, and there is no need to change the warp feeding gear; when changing the warp beam, there is no need to manually turn the warp beam, just a simple button is needed.

[0250] In this embodiment, a double needle bed high-speed jacquard machine is used for weaving. The warp chain knitting organization of the ground comb bar GB1 and the change stitch organization of the jacquard bar JK2-1 and the jacquard bar JK2-2 are woven to form a plain jacquard area 42 with a chain warp oblique, and can also be woven into a plain jacquard area 42 with a chain warp plain organization according to design requirements. The jacquard bar JK1-1 and the jacquard bar JK1-2 utilize the characteristics of the missing pad organization that does not do the front pad yarn of the needle hook in some horizontal rows but only swings between the needles, combined with the empty threading yarn change of the comb bar and the unique creel negative warp feeding method, the floating yarn jacquard design is freely performed in the floating yarn jacquard area 41, thereby forming the second floating yarn jacquard area 412.

[0253] The present embodiment provides a sandwich mesh with floating yarn jacquard, including a mesh body integrally woven by a double needle bed high-speed warp knitting machine, wherein the mesh body includes a surface layer 1, a bottom layer 2, an intermediate layer 3 and a floating yarn jacquard layer 4.

[0254] The surface layer 1 includes a plurality of first yarns, and the plurality of first yarns are cross-woven to form the surface layer 1.

[0257] Reference Figure 4 , Figure 4 It is a second cross-sectional view of the sandwich mesh with floating yarn jacquard of the present invention;

[0258] The floating yarn jacquard layer 4 is woven on the surface layer 1 and includes a floating yarn jacquard area 41 and a plain jacquard area 42. The floating yarn jacquard layer 4 includes a plurality of fourth yarns, and the plurality of fourth yarns are cross-woven with the plurality of first yarns to form the plain jacquard area 42. The plurality of fourth yarns are separately woven with the plurality of first yarns to form the floating yarn jacquard area 41. The plurality of fourth yarns in the floating yarn jacquard area 41 are separately woven to form the first floating yarn jacquard area 411.

[0259] In this embodiment, multiple fourth yarns are woven separately from multiple first yarns, and multiple fourth yarns are also woven separately, that is, each coil is formed by the same warp yarn, each warp yarn is always on the same needle during weaving, and the longitudinal rows are not connected with each other. The lack of padding structure is used, and the yarn is not padded before the needle hook in some horizontal rows but only swings between the needles. Combined with the change of the empty threading of the comb and the unique negative warp feeding method of the creel, a sandwich mesh cloth with floating yarns between two vertical strips is formed.

[0260] The floating yarn jacquard layer 4 also includes multiple sixth yarns, which are cross-woven with multiple first yarns and multiple fourth yarns in the plain jacquard area 42. The multiple sixth yarns are separately woven from the multiple first yarns in the floating yarn jacquard area 41 and cross-woven with the multiple fourth yarns to form a third floating yarn jacquard area 413 with a mesh 4131.

[0261] The first yarn is a transparent yarn, which can be transparent fish silk, TPU monofilament, TPEE monofilament, or high-strength monofilament, which can not only enhance the transparent visual effect, but also make the mesh cloth slightly elastic when it is woven, thereby enhancing the extensibility of the mesh cloth.

[0262] The fourth yarn and the sixth yarn are both colored yarns, and the color of the sixth yarn is inconsistent with the color of the fourth yarn. The colored yarn can be mixed color linen low-elastic yarn, space-dyed fantasy color low-elastic yarn, seven-color silk, luminous yarn, reflective yarn, and the properties of colored yarn are used to enrich the color effect of floating yarn and design new functional mesh fabrics.

[0263] The surface layer 1 has a plurality of air holes 11. By increasing the air holes 11, the air permeability of the mesh is greatly enhanced.

[0264] In this embodiment, the sixth yarn is cross-woven with the fourth yarn so that the fourth yarn, which is originally unconnected, is extended in the direction to form a floating yarn jacquard with mesh holes 4131 under the action of the sixth yarn and the first yarn. That is, the oblique missing pad weaving is performed by utilizing the change of the empty yarn passing through the comb and the unique negative warp feeding method of the yarn frame. The vertical rows are unconnected with each other and will be affected by the tension of the mesh cloth itself, extending in the direction to form mesh holes 4131. The missing pad part is not used as the front pad yarn of the needle hook in some horizontal rows but only swings between the needles, which will be affected by the tension of the mesh holes 4131 of the mesh cloth to form a hole centerline effect.

[0285] S4. Weaving

[0286] The ground comb bar GB1 uses the double needle bed process 0-0 / 0-1 / 1-1 / 1-0 / / , alternately pads yarn into loops on the front needle bed and the rear needle bed, uses the chain stitch structure 0-1 / 1-0 / / on the front needle bed, and uses the weft insertion structure 0-0 / 1-1 / / on the rear needle bed to form the surface layer 1.

[0291] The ground comb bar GB57 uses the double needle bed process 1-0 / 2-2 / 2-3 / 1-1 / / , and the front needle bed and the rear needle bed are alternately used for yarn padding and looping. The front needle bed uses the warp knitting weft insertion structure 2-2 / 1-1 / / for weft insertion weaving, and the rear needle bed uses the warp knitting warp pile structure 1-0 / 2-3 / / for looping weaving.

[0292] In this weaving step, the ground comb bar GB1 follows the weft insertion structure 0-0 / 1-1 / / on the rear needle bed.

The front section of the tube is equipped with a row of aluminum strips and a ring-type pressure tensioner. The creel uses negative warp feeding. Through the creel's negative warp feeding method, the tension of each yarn can be accurately controlled, making the tension adjustment of the jacquard comb more flexible, which helps to enrich the jacquard comb's jacquard effect. If the disc head positive warp feeding is used: the tension control of the jacquard comb is uniformly fed by the warp beam, which means that the tension of the jacquard comb is limited, and the jacquard jacquard effect becomes too limited, which is not conducive to the innovation of jacquard products.

[0295] The warp beam positively feeds the warp yarn uniformly through the warp beams in front and behind the jacquard machine. Through the positive warp beam feeding, a higher machine speed can be achieved, which improves production efficiency; changing the warp feeding amount is convenient and quick, and there is no need to change the warp feeding gear; when changing the warp beam, there is no need to manually turn the warp beam, just a simple button is needed.

[0296] This embodiment uses a double needle bed high-speed jacquard machine for weaving. The warp knitting chain structure of the ground comb bar GB1 and the local pad-less structure of the jacquard bars JK1-1 and JK1-2 are used to weave the oblique pad-less fabric by using the empty threading yarn change of the comb bar and the unique negative warp feeding method of the creel. The longitudinal rows of the chain part of the mesh cloth are not connected to each other and will be affected by the tension of the mesh cloth itself, extending to the left and right to form the mesh 4131 effect. The pad-less part does not do the front padding of the needle hook in some horizontal rows but only swings between the needles, which will be affected by the tension of the fabric mesh 4131 to form the hole centerline effect, thereby forming the third floating yarn jacquard area 413. The change needle method organization of the jacquard bars JK11-1, the jacquard bars JK1-2 and the jacquard bars JK2-1 and the jacquard bars JK2-2 is a warp plain organization in the same direction for superimposed weaving, which plays a role in strengthening the physical properties of the mesh cloth.
