Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a 32-needle concave-convex warp knitted mesh fabric and a manufacturing method thereof. Background Art

[0002] At present, warp knitting manufacturers generally use 24-needle warp knitting machines. Due to the coarse needles of 24-needle warp knitting machines, when weaving concave and convex warp knitted mesh cloths, in order to ensure the concave and convex three-dimensional effect, 70 and 100D spandex core-spun yarns are mainly used when elastic yarns are used, and the coarse yarns are stretched to ensure the concave and convex three-dimensional shape. The D number used for the overall material cannot use finer materials due to the number of needles, resulting in larger gaps between the yarns of the concave and convex three-dimensional warp knitted mesh cloth woven by traditional 24-needle warp knitting machines, which appears to be relatively rough; if the 24-needle warp knitting machine uses finer yarn materials for weaving, it is easy to have loose gaps and the yarns are easily worn and broken.

[0003] At the same time, as consumers in the market have increasingly higher requirements for lightweight fabrics, using yarns with large D numbers for weaving will inevitably fail to reduce the unit weight of warp knitted mesh fabrics, and cannot meet the market demand for lightweight fabrics. Summary of the invention

[0004] In order to solve the technical problems that the above-mentioned prior art concave convex warp knitted mesh cannot use finer yarns to meet the market demand for lightweight fabrics, and the gaps between the yarns are large and appear relatively rough, the present invention provides a 32-needle concave convex warp knitted mesh and a production method thereof.

[0005] [The present invention discloses a 32-needle concave-convex warp knitted mesh] A 32-needle concave-convex warp knitted mesh fabric comprises a mesh fabric body integrally woven by a 32-needle jacquard warp knitting machine. The mesh fabric body comprises a surface layer, a middle layer and a bottom layer from top to bottom, wherein a convex area and a concave area are arranged on the surface layer.

[0006] Preferably, the surface layer is a non-elastic plane layer, and a plurality of raised areas are arranged on the surface layer, and the raised heights of the plurality of raised areas are different.

[0007] Preferably, the surface layer is a non-elastic plane layer, and a plurality of recessed areas are arranged on the surface layer, and the recessed depths of the plurality of recessed areas are different.

[0008] Preferably, the surface layer is a non-elastic plane layer, and there are multiple raised areas and recessed areas arranged on the surface layer, and the raised heights and recessed depths between the raised areas and the recessed areas are different.

[0009] Preferably, the bottom layer is woven from a mixture of 50-75D non-elastic and elastic yarns.

[0010] [The present invention also discloses a method for making a 32-needle concave-convex warp knitted mesh] A method for manufacturing a 32-needle concave-convex warp knitted mesh fabric, comprising: Guide bar setting: 32-needle jacquard warp knitting machine is used for weaving; Yarn threading on the comb bar: After warping, the yarn of 20~75D is selected and threaded on the jacquard comb bar and the ground comb comb bar according to the weaving process; Mesh cloth weaving: using at least one ground comb bar and a pair of jacquard comb bars to weave on the front needle bed to form the surface layer of the mesh cloth body, using at least two ground comb bars to use elastic yarn and non-elastic yarn to carry out mixed weaving on the rear needle bed to form the bottom layer of the mesh cloth body, using at least one ground comb bar to weave back and forth between the front needle bed and the rear needle bed to form the middle layer of the mesh cloth body; using at least one pair of jacquard comb bars to use elastic yarn to weave back and forth between the front needle bed and the rear needle bed, the surface layer knitted by the front needle bed is pulled toward the rear needle bed to form a concave area of ​​the surface layer, and at the same time, the knitting yarn of the surface layer is squeezed and woven to form a convex area of ​​the surface layer.

[0011] Preferably, a pair of jacquard bars that are reciprocatingly knitted on the front needle bed and the rear needle bed are all knitted at the bottom layer position corresponding to the raised area, so that the yarn squeezes the raised area to the utmost, thereby forming a raised area of ​​the highest height. By reducing the low-layer area corresponding to the raised area woven in the raised area, the squeezing force on the raised area is reduced, thereby reducing the raised height of the raised area, and then forming multiple raised areas of different heights.

[0012] Preferably, a ground comb bar and a pair of jacquard comb bars woven on the surface layer are all woven on the surface layer without yarn padding on the bottom layer, and a pair of jacquard comb bars woven back and forth on the front and rear needle beds are also all woven on the surface layer, thereby forming a mixed color raised area slightly higher than the surface layer.

[0013] By adopting the above technical solution, the beneficial effects of the present invention are: 1. Compared with the prior art, this solution uses 20~75D yarns for precision weaving through a 32-needle jacquard warp knitting machine. Compared with the 24-needle prior art, the warp knitted mesh is more dense and has a better feel.

[0014] 2. Compared with the existing technology, the traditional 24-needle concave-convex process uses 100D CD yarn on the fabric surface layer, 30D monofilament on the middle layer, 70 / 100D elastic yarn on the jacquard comb, and 75D low-elastic yarn on the bottom layer of the warp knitted mesh. The overall weight is about 445.9G / M²; while this solution uses 50D yarn on the surface layer, and the three combs reduce the D number of the yarn by 150D as a whole. The middle layer uses 20D monofilament, which is reduced by 10D, and the elastic yarn is reduced by 25D. The finished product of this solution weighs 386.7G / M², and each square of warp knitted mesh is reduced by 59.2G, further improving the lightweight performance of the product.

[0019] 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.

[0020] [A 32-needle concave-convex warp knitted mesh fabric provided by the present invention] A 32-needle concave-convex warp knitted mesh fabric comprises a mesh fabric body 1 integrally woven by a 32-needle jacquard warp knitting machine, wherein the mesh fabric body 1 comprises a surface layer 2, an intermediate layer 3 and a bottom layer 4 from top to bottom, wherein the surface layer 2 is a non-elastic plane layer 2 and is provided with a raised area 5 and a sunken area 6, and the raised area 5 and the sunken area 6 provided on the surface layer 2 can be multiple, and can be set to have a raised height and / or a sunken depth of multiple different dimensions, or can be set to be spaced apart in multiple dimensions of the same dimension. The lower layer of the mesh fabric body 1 is woven from a mixture of non-elastic and elastic yarns of 50-75D.

[0021] [A weaving method for a 32-needle concave-convex warp knitted mesh fabric provided by the present invention] A method for making a 32-needle concave-convex warp knitted mesh fabric comprises three steps of setting a comb bar, threading a comb bar and knitting a mesh fabric, which are respectively: Guide bar setting: 32-needle jacquard warp knitting machine is used for weaving; Yarn threading on comb: 20~75D yarn is selected and threaded on jacquard comb and ground comb according to the knitting process; Mesh cloth weaving: using at least one ground comb bar and a pair of jacquard comb bars to weave on the front needle bed to form the surface layer 2 of the mesh cloth body 1, using at least two ground comb bars to use elastic yarn and non-elastic yarn to carry out mixed weaving on the rear needle bed to form the lower layer of the mesh cloth body 1, using at least one ground comb bar to weave back and forth between the front needle bed and the rear needle bed to form the middle layer 3 of the mesh cloth body 1; using at least one pair of jacquard comb bars to use elastic yarn to weave back and forth between the front needle bed and the rear needle bed, the surface layer 2 formed by the knitting of the front needle bed is pulled toward the rear needle bed to form a concave area 6 of the surface layer 2, and at the same time, the knitting yarn of the surface layer 2 is squeezed and woven to form a convex area 5 of the surface layer 2.

[0022] The method for setting the raised area 5 is to weave a pair of jacquard bars of the mesh cloth on the front needle bed and the rear needle bed at the lower position corresponding to the raised area 5, and control the raised height of the raised area 5 by controlling the proportion of the area of ​​the raised area 5 woven on the bottom layer 4. If all the yarns are woven on the bottom layer 4, the raised height of the raised area 5 will reach the highest. If all the yarns in the raised area 5 are woven on the surface layer 2, the raised height is only the height of the yarn diameter, and the raised height is the lowest. By controlling the area ratio of the yarn weaving bottom layer 4 in different raised areas 5, it is achieved that the same mesh body 1 has multiple raised areas 5 with different raised heights.

[0023] However, if a ground comb bar and a pair of jacquard comb bars of the woven surface layer 2, together with a pair of jacquard comb bars of the woven raised area 5 are all woven on the surface layer 2 without yarn padding on the bottom layer 4, a mixed color raised area 5 slightly higher than the surface layer 2 will be produced due to the different colors and materials of the yarns between the comb bars.

[0030] Those skilled in the art should clearly know that in the process of making this solution, the following points should also be noted: 1. Surface layer 2: 50DCD low-elastic and non-elastic yarn is used on the combs GB1, JB1.1, and JB1.2 to weave the mesh body 1 surface layer 2, forming a non-elastic area to make mesh, thick plain cloth, and thin plain cloth. The number of the weaving yarn is: GB1 0-1 / 1-1 / 1-0 / 0-0 / / , jacquard JB1.1 and JB1.2 adopt the change organization 1-0 / 1-1 / 1-2 / 1-1 / / , when the offset signals of JB1.1 and JB1.2 are used to make mesh, the jacquard pad yarn digital number is 2-1 / 1-1 / 2-3 / 1-1 / / and 1-0 / 1-1 / 1-2 / 1-1 / / combination, when the offset signals of JB1.1 and JB1.2 are used to make thick plain weave, the jacquard pad yarn digital number is 1-0 / 1-1 / 2-3 / 1-1 / / , when the offset signals of JB1.1 and JB1.2 are used to make thin plain weave, the jacquard pad yarn digital number is 1-0 / 1-1 / 1-2 / 1-1 / / , the surface layer 2 of the mesh body 1 is an independent non-elastic plane layer 2, standing on the middle layer 3, and has a sandwich Q elastic retraction effect; 2. The 75D low-elastic spandex core-spun yarn on the jacquard bars JB2.1 and JB2.2 is freely woven with elastic yarn on the surface layer 2 and the bottom layer 4, and the yarn is pulled mutually to form concave and convex area meshes, thick plain cloth, and thin plain cloth shapes. The jacquard bar JB2.1 and JB2.2 weave the inlay yarn digital number is 1-0 / 1-0 / 1-2 / 1-2 / / . When the JB2.1 and JB2.2 offset signals are used to make the surface layer 2 mesh, the jacquard inlay yarn digital number is 2-1 / 1-1 / 1-2 / 2-2 / / , when the offset signals of JB2.1 and JB2.2 are used as the bottom layer with 4 meshes, the Jacquard yarn digital number is 1-1 / 2-1 / 2-2 / 1-2 / / , when the offset signals of JB2.1 and JB2.2 are used as the top layer with 2 thick plain weaves, the Jacquard yarn digital number is 1-0 / 1-1 / 2-3 / 2-2 / / , when the offset signals of JB2.1 and JB2.2 are used as the bottom layer with 4 thick plain weaves, the Jacquard yarn digital number is 1-0 / 1-1 / 2-3 / 2-2 / / , The code is 1-1 / 1-0 / 2-2 / 2-3 / / .

After the upgrade, the 32-needle yarn used in each comb bar is lower, the surface layer 2 is reduced by 150D yarn D, the monofilament is reduced by 10D, and the elastic yarn is reduced by 25D. The gram weight of the concave-convex finished product of the present invention is about 386.7G / M², which improves the lightweight performance of the product; 7.

JB2.1 and JB2.2 use at least a few single-point jacquards to the mesh body 1 surface layer 2, and use the elasticity to pull the highest area of ​​the surface layer 2 down to a height. JB2.1, JB2.2, and a large area are woven on the mesh body 1 bottom layer 4. GB7 and GB8 are all woven on the mesh body 1 bottom layer 4. GB2 is the middle layer 3 that connects the surface and the bottom. The overall working principle is the same as the first concave-convex area. Because the jacquard is elastic, it is pulled down to form the second concave-convex height. ③ The Nth concave-convex area, with the amount of JB2.1, JB2.2, and jacquard to the surface layer 2 area, forms high and low convex areas 5 in different areas; ④ The lowest area, the mesh body 1 surface layer 2 combs GB1, JB1.1, JB1.2 are all woven on the surface layer 2, and when the ratio of JB2.1, JB2.2 jacquard to the surface layer 2 and the bottom layer 4 is proportional, the elastic tension of the non-elastic area of ​​the surface layer 2 is the same as that of the elastic area of ​​JB2.1, JB2.2 to the bottom layer 4, and the surface layer 2 is pulled down to the lowest point as a whole, forming the lowest area; ⑤ Mixed color convex area, mesh body 1 surface layer 2 combs GB1, JB1.1, JB1.2 are all woven on surface layer 2, JB2.1, JB2.2 jacquard are also all on surface layer 2, without any padding to bottom layer 4, GB7, GB8 are all woven on mesh body 1 bottom layer 4, GB2 is the middle layer 3 connecting the surface and bottom, in the whole space, large area of ​​non-elastic and large area of ​​elastic surface layer 2 are fused together at the same time, the composition ratio is higher than that of bottom layer 4, and the tension is looser than the lowest area on the edge to form a mixed color convex effect.

8. The method according to claim 7, characterized in that: At least one pair of jacquard bars are woven entirely on the bottom layer of the raised area to form a raised area of ​​the highest height, and the raised height of the raised area is reduced by reducing the area woven on the bottom layer.

9. The method according to claim 7, characterized in that: A ground comb bar and a pair of jacquard comb bars woven on the surface layer are all woven on the surface layer without yarn padding on the bottom layer; A pair of jacquard bars that knit back and forth on the front and rear needle beds are also all knitted on the surface layer, thereby forming a mixed color raised area slightly higher than the surface layer.
