Description

Technical Field

[0001] The invention relates to the technical field of mesh cloth, in particular to a sandwich mesh cloth with a single-sided structural effect 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. Sandwich mesh fabrics with jacquard effects have appeared on the market, and usually the jacquard effect is reflected on the surface of the sandwich mesh fabric (i.e. the surface of the top layer and the surface of the bottom layer in the sandwich mesh fabric). Therefore, the overall effect of the sandwich mesh fabric with jacquard effect on the market is a double-sided structural effect, the overall thickness is thick, the jacquard effect is single, and the air permeability is poor.

[0004] In addition, there are two types of mesh fabrics currently on the market, as follows:

[0005] (1) Single-sided warp knitted fabrics are woven in a single-needle bed warp knitting machine. One side of the fabric is composed of coils, while the other side is distributed with extension lines of the coils. Due to the existence of extension lines, the single-sided warp knitted fabric has poor structural stability and poor aesthetic effect;

[0006] (2) Double-sided warp knitted fabric, which is woven in a double-needle bed warp knitting machine. Both sides of the fabric are composed of coils, and the extension lines of the coils are in the coils on both sides, that is, jacquard weaving cannot be performed on the back side of the fabric, and the jacquard effect on the back side of the fabric cannot be reflected. In addition, the overall thickness of the fabric is relatively thick and the air permeability is poor. Summary of the invention

[0007] 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.

[0008] The object of the present invention is to overcome the above-mentioned shortcomings and provide a sandwich mesh with a single-sided structural effect. The mesh is woven integrally by a double-needle-bed high-speed warp knitting machine or a double-needle-bed high-speed jacquard machine. The mesh includes a surface layer, a jacquard layer and a connecting layer for connecting the surface layer and the jacquard layer. It has the characteristics of high performance and good chemical structure stability. The mesh also meets the characteristics of single-sided warp knitted fabrics and double-sided warp knitted fabrics. Both sides of the mesh are composed of coils, and the extension lines of the coils are in the coils on both sides. The extension lines of the coils can be clearly seen on the back of the mesh, and the extension lines are used to perform multi-comb jacquard to arbitrarily design pattern effects. The appearance pattern is unique, the structural stability is high, and the air permeability is strong.

[0009] To achieve the above-mentioned purpose, the technical solution of the present invention is: a sandwich mesh with a single-sided structural effect, including a mesh body woven in one piece, the mesh body including a surface layer, a jacquard layer woven below the surface layer, and a connecting layer for connecting the surface layer and the jacquard layer. The surface layer includes a plurality of first yarns, and a plurality of the first yarns are cross-woven to form the surface layer; the jacquard layer includes a plurality of second yarns and a plurality of third yarns, and a plurality of the second yarns are cross-woven to form a first jacquard structure with a coil structure, and the coil structure includes a loop coil structure and an extended coil structure, and a plurality of the third yarns are cross-woven with the extended coil structure to form a second jacquard structure, and the second jacquard structure is located below the first jacquard structure; the connecting layer includes a plurality of fourth yarns, and a plurality of fourth yarns are cross-woven to form the connecting layer, and the fourth yarn has yarns fed to the bottom of the jacquard layer.

[0010] Preferably, the coil structure is woven from the second yarn change-patterned structure.

[0011] Preferably, the coil structure is woven from the second yarn change weft insertion structure.

[0012] Preferably, the coil structure is woven by the second yarn path-changing lack-pressure warp knitting structure.

[0013] Preferably, the coil structure is woven from a single-sided terry structure with a changed second yarn pattern.

[0014] Preferably, the second jacquard structure is one or a combination of two or more of mesh jacquard, missing pad jacquard and heavy warp jacquard.

[0046] S4. Weaving steps

[0047] The ground comb bar GB1 lays yarn on the front needle bed to form the first layer of yarn, and uses a variable warp knitting structure to form the surface layer. The ground comb bar GB2 lays yarn alternately on the front needle bed and the rear needle bed in sequence to form the second layer of yarn, and uses a double needle bed process to form the connecting layer. The jacquard comb bars JK1-1 and JK1-2 lay yarn on the front needle bed to form the third and fourth layers of yarn, and use a variable jacquard structure to form the first jacquard structure in the jacquard layer. The ground comb bars GB5 and GB6 lay yarn on the front needle bed to form the fifth and sixth layers of yarn, and use a variable warp knitting structure to form the second jacquard structure in the jacquard layer.

[0050] By adopting the above technical solution, the beneficial effects of the present invention are:

[0051] 1. The present invention forms a surface layer by cross-weaving a first yarn, and forms a first jacquard structure with a coil structure by cross-weaving a second yarn on the reverse side of the surface layer. Meanwhile, the coil structure comprises a looped coil structure and an extended coil structure. A third yarn is combined with the extended coil on the reverse side of the surface layer and cross-weaved to form a second jacquard structure. Finally, a fourth yarn is cross-weaved to form a connecting layer. Meanwhile, the connecting layer plays a role in fixing the second jacquard structure, so that the jacquard effect of the sandwich mesh is richer and has a single-sided structural effect.

[0052] 2. The present invention performs primary jacquard and secondary jacquard on the reverse side of the surface layer, so that the sandwich mesh cloth can simultaneously meet the characteristics of single-sided warp knitted fabric and double-sided warp knitted fabric. Both sides of the fabric are composed of coils, and the extension lines of the coils are in the coils on both sides. The extension lines of the coils can be clearly seen on the reverse side, and the extension lines are used to perform multi-comb jacquard to arbitrarily design pattern effects.

[0053] 3. The present invention utilizes the unique advantages of a double-needle-bar high-speed warp knitting machine and combines it with the change of the empty threading of the comb bar to perform warp knitting multi-comb jacquard or warp knitting multi-comb iterative jacquard. The change of the empty threading of the comb bar can arbitrarily match the organization design jacquard effect according to design needs, such as using multiple comb bar change pad-less organization, multiple comb bar change weft lining organization, multiple comb bar change pressure-less organization, single-sided terry organization, etc. for jacquard, and also uses the characteristics of each organization to mix and match jacquard, highlighting the pattern diversity of the sandwich mesh cloth with a single-sided structural effect.

[0054] 4. The present invention utilizes the unique advantages of the double-needle-bar jacquard machine to carry out the diversity characteristics of the 1-6 half-machine jacquard bar offset signal and combines it with the multi-bar empty threading yarn change design to achieve a variety of shoe-type jacquard effects. For example, the mesh, thin, thick, lack of padding, heavy warp and other jacquard structures formed by the jacquard offset signal are mixed with the multi-bar change lack of padding structure, multi-bar change weft lining structure, multi-bar change lack of pressure structure, single-sided terry structure, etc. to create a jacquard rich integrated shoe pattern effect, highlighting the pattern diversity of the sandwich mesh with a single-sided structural effect.

[0055] 5. The present invention arranges the comb bar of the knitting connection layer to adopt a double needle bed process, and the yarns are alternately placed in the front needle bed and the rear needle bed to form loops for knitting, so that the structure of the sandwich mesh cloth is more stable, does not delaminate, and has the beneficial effects of air conduction, wrinkle resistance, shape retention, strong 3D stereoscopic effect, etc.

[0085] The present embodiment provides a sandwich mesh with a single-sided structural effect, including a mesh body woven in one piece. The mesh body includes a surface layer 1, a jacquard layer 2, and a connecting layer 3. The jacquard layer 2 is woven under the surface layer 1, and the connecting layer 3 is woven between the surface layer 1 and the jacquard layer 2 and is used to connect the surface layer 1 and the jacquard layer 2.

[0087] The first yarn 11 is not restricted and can use environmentally friendly yarn, that is, it is extracted from discarded mineral water bottles and cola bottles. Its characteristics have made certain contributions to reducing air pollution and controlling the greenhouse effect. You can also use transparent yarns such as transparent fish silk, TPU monofilament, TPEE monofilament, high-strength monofilament, etc., which can not only enhance the transparent visual effect, but also make the fabric slightly elastic when weaving to enhance the extensibility of the fabric. You can also use mixed color linen low-elastic yarn and segment-dyed fantasy color low-elastic yarn to enrich the color effect of the mesh.

[0088] The jacquard layer 2 includes a plurality of second yarns 211 and a plurality of third yarns 221. The plurality of second yarns 211 are cross-woven to form a first jacquard structure 21 having a coil structure 212 (i.e., the second yarn 211 is jacquard-designed on the reverse side of the surface layer 1, thereby forming the first jacquard structure 21), and the coil structure 212 includes a loop coil structure 2121 and an extended coil structure 2122.

The connecting layer 3 is used as an intermediate connecting part to provide a pile layer for the sandwich mesh with a single-sided structural effect. This area connects the surface layer 1 and the jacquard layer 2 to prevent the sandwich mesh from delaminating, and has the beneficial effects of air conduction, wrinkle resistance, shape retention, and strong 3D stereoscopic effect; this area can control the gear warp feeding amount to freely adjust the thickness of the comb pile layer.

[0090] The coil structure 212 is formed by weaving the second yarn 211 in a modified pad structure.

[0091] The second jacquard structure 22 is a mesh jacquard.

[0092] The second jacquard structure 22 is regular.

[0093] In this embodiment, the surface layer 1 is formed by cross-weaving the first yarn 11, and the second yarn 211 is cross-woven on the reverse side of the surface layer 1 to form a first jacquard structure 21 with a coil structure 212. At the same time, the coil structure 212 has a loop coil structure 2121 and an extended coil structure 2122. The third yarn 221 is combined with the extended coil on the reverse side of the surface layer 1 to cross-weave to form a second jacquard structure 22. Finally, the fourth yarn 31 is cross-woven to form a connecting layer 3. At the same time, the connecting layer 3 serves to fix the second jacquard structure 22.

[0094] In this embodiment, primary jacquard and secondary jacquard are performed on the reverse side of the surface layer 1, so that the sandwich mesh cloth can simultaneously meet the characteristics of single-sided warp knitted fabric and double-sided warp knitted fabric. Both sides of the fabric are composed of coils, and the extension lines of the coils are in the coils on both sides. The extension lines of the coils can be clearly seen on the reverse side, and the extension lines can be used to perform multi-comb jacquard to arbitrarily design pattern effects.

[0155] The warp feed rate of the gear corresponding to the ground comb bar GB6 is 2400-3400mm / lac.

[0156] S4. Weaving steps

[0157] The ground comb bar GB1 lays yarn on the front needle bed to form the first layer of yarn, and runs a variable warp knitting structure 0-1 / 4-3 / / to form the surface layer 1.

[0158] The ground comb bar GB2 forms the third layer of yarn by padding on the front needle bed, and changes the pad-less structure (1-0 / 0-1)*3 / (0-0 / 0-0)*3 / 0-0 / 0-1 / / to form the first jacquard structure 21 in the jacquard layer 2. The ground comb bar GB3 forms the fourth layer of yarn by padding on the front needle bed, and changes the pad-less structure (0-0 / 0-0)*3 / (1-0 / 0-1)*3 / 0-1 / 0-0 / / to form the first jacquard structure 21 in the jacquard layer 2. Among them, the looped part is (1-0 / 0-1)*3, 0-1 / / , and the pad-less part is (0-0 / 0-0)*3, 0-0 / / . Through a reasonable process combined with the change of the empty threading of the comb bar, a jacquard is performed, and a local extended line floating line pattern effect is formed on the reverse side of the process, thereby forming the first jacquard structure 21.

[0159] The ground comb bar GB4 pads yarn on the front needle bed to form the fifth layer of yarn, and changes the weft inlay structure to 0-0 / 4-4 / 3-3 / 4-4 / 0-0 / 4-4 / 3-3 / 7-7 / 3-3 / 4-4 / 3-3 / 7-7 / 3-3 / 4-4 / / ; the ground comb bar GB5 pads yarn on the front needle bed to form the sixth layer of yarn, and changes the weft inlay structure to 7-7 / 3-3 / 4-4 / 3-3 / 7-7 / 3-3 / 4-4 / 0-0 / 4-4 / 3-3 / 4-4 / 0-0 / 4-4 / 3-3 / / ; the ground comb bar GB2 and the ground comb bar GB3 change the pattern effect of the floating line with missing pad extension line, and through reasonable technology combined with the change of the empty yarn of the comb bar to enrich the pattern for secondary jacquard, the jacquard single-sided structure floating line jacquard area is designed, thereby forming the second jacquard structure 22.

[0160] The ground comb bar GB6 alternately pads yarn on the front needle bed and the rear needle bed to form the second layer of yarn, and uses a double needle bed process to form the connecting layer 3. Among them, the ground comb bar GB6 pads yarn on the front needle bed and uses a variable warp knitting chain structure 1-0 / 0-1 / / to perform loop knitting, and the ground comb bar GB6 pads yarn on the rear needle bed and uses a variable warp knitting chain structure 1-0 / 0-1 / / to perform loop knitting.

[0161] In this embodiment, the ground comb bar GB6 serves as the middle connecting layer 3, providing a pile layer for the sandwich mesh with a single-sided structural effect. This area connects the surface layer 1 and the jacquard layer 2 to prevent the sandwich mesh from delaminating, and has the beneficial effects of air conduction, wrinkle resistance, shape retention, and strong 3D stereoscopic effect. This area can control the gear warp feeding amount to freely adjust the thickness of the pile layer. In addition, this area plays a role in fixing the ground comb bar GB4 and the ground comb bar GB5 to change the weft insertion jacquard layer 2, so that the yarn layer does not fall apart because the weft insertion structure does not do the needle front padding, but only does the needle back lateral movement.

[0162] This embodiment utilizes the unique advantages of a double-needle-bar high-speed warp knitting machine and combines the empty threading variation of the comb bar to perform warp knitting multi-comb jacquard or warp knitting multi-comb iterative jacquard. The combination of the empty threading variation of the comb bar can arbitrarily match the organization design jacquard effect according to design needs, such as: using multiple comb bar variation lacking pad organization, multiple comb bar variation weft lining organization, multiple comb bar variation lacking pressure organization, single-sided terry organization, etc. for jacquard alone, and also using the characteristics of each organization to mix and match jacquard, highlighting the pattern diversity of the sandwich mesh with a single-sided structural effect.

[0163] During the weaving process, this embodiment satisfies the characteristics of single-sided warp knitted fabric and double-sided warp knitted fabric at the same time. Both sides of the fabric are composed of coils, and the extension lines of the coils are in the coils on both sides. The extension lines of the coils can be clearly seen on the back side, and the extension lines can be used to perform multi-comb jacquard to arbitrarily design pattern effects.

The jacquard bars JK1-1 and JK1-2 use the jacquard basic structure 1-0 / 1-1 / 1-2 / 1-1 / / , and the back extension line is used to form the first jacquard structure 21 of the jacquard layer 2 on the mattress yarn of the front needle. The surface layer 1 can use the chain weave structure 2-1 / 1-2 / / in combination with the offset signal, and the back side of the surface layer 1 can use the chain weave extension line to form a regular vertical stripe effect (i.e., the first jacquard structure 21); the surface layer 1 can use the warp plain structure 1-0 / 1-2 / / in combination with the offset signal, and the surface layer 1 can use the warp plain structure 1-0 / 1-2 / / in combination with the offset signal. On the reverse side, the warp pile structure back extension line is used to form a thinning effect (i.e., the first jacquard structure 21); the offset signal can be combined to form a thick effect (i.e., the first jacquard structure 21) by using the warp pile structure back extension line on the reverse side of the surface layer 1; the offset signal can also be combined to form a missing pad structure 1-0 / 1-1 / 2-2 / 1-1 / / on the reverse side of the surface layer 1, and the missing pad structure is used in some horizontal rows without making a front pad yarn of the needle hook on the reverse side of the surface layer 1, but the needle swings to form a linear hanging effect (i.e., the first jacquard structure 21); and then the ground comb bar GB5 and the ground comb bar GB6 are used to perform a secondary jacquard effect (i.e., the second jacquard structure 22) to enrich the diversity and characteristics of the shoe pattern.

[0196] This embodiment utilizes the unique advantages of the double-needle-bar jacquard machine to combine the diversity of 1-6 half-machine jacquard bar offset signals with the multi-bar empty threading yarn variation design to achieve a variety of shoe-shaped jacquard effects. For example, the mesh, thin, thick, lack of padding, heavy warp and other jacquard structures formed by the jacquard offset signal are mixed with multi-bar variation lack of padding structure, multi-bar variation weft lining structure, multi-bar variation lack of pressure structure, single-sided terry structure, etc. to achieve a jacquard rich integrated shoe pattern effect, highlighting the pattern diversity of the sandwich mesh with a single-sided structural effect.

[0197] During the weaving process, this embodiment satisfies the characteristics of single-sided warp knitted fabric and double-sided warp knitted fabric at the same time. Both sides of the fabric are composed of coils, and the extension lines of the coils are in the coils on both sides. The extension lines of the coils can be clearly seen on the back side, and the extension lines can be used to perform multi-comb jacquard to arbitrarily design pattern effects.
