Description

Technical Field

[0001] The present application relates to the technical field of warp knitted fabrics, and in particular to a multi-jacquard composite interlaced jacquard warp knitted fabric and a knitting method thereof. Background Art

[0002] The warp knitted fabrics currently on the market mainly include single jacquard fabrics, multi-comb and single jacquard composite jacquard fabrics, and double jacquard jacquard fabrics.

[0003] The basic fabric structure of single jacquard fabric (including composite with multi-comb) is thick, thin and mesh, the fabric layering is limited, and the jacquard yarn color variety is limited. The pattern formed is relatively flat, the three-dimensional effect is poor, and the color is single.

[0004] Double jacquard fabric has improved the defects of single jacquard jacquard fabric to a certain extent. It can realize two-color jacquard with slightly richer layers. It is generally used on double needle bed warp knitting equipment, with one jacquard on one needle bed.

[0005] However, when the required jacquard fabric is a tubular three-dimensional fabric or a patterned fabric with rich layers or a jacquard fabric with an independent logo, single jacquard or double jacquard cannot be achieved. As a result, multi-jacquard warp knitted fabrics appeared on the market. However, the jacquard bars in the jacquard device of the multi-jacquard warp knitted fabrics (two half-machine jacquard bars) are all loop-forming or weft-inserted types. Therefore, the pattern color and tissue effect of the multi-jacquard warp knitted fabric are relatively simple, and the performance is also poor.

[0006] For example, Chinese patent application No. 201910704273.7, named as a multi-jacquard warp knitting machine, weaving method and the resulting woven fabric, mainly depends on the different configuration and arrangement of the jacquard comb and the ground comb, and the woven fabric effect is also different. For example, if the jacquard combs are placed in front of n ground combs, the pattern effect formed is relatively flat; if the jacquard combs are placed behind n ground combs, the jacquard pattern effect in the fabric is more three-dimensional with the invisible effect of the ground combs; if the jacquard combs are placed between n ground combs, the pattern has a stronger sense of hierarchy. These configuration methods will greatly expand the space for pattern design selection, enrich the pattern organization effect, and increase the added value of the product. The two half-machine jacquard combs corresponding to the above-mentioned jacquard combs are both loop-forming or weft-inserted, which greatly restricts the structure, performance, pattern, etc. of the multi-jacquard warp knitted fabric, and cannot meet the needs of different consumers for the structure, performance, pattern, etc. of the multi-jacquard warp knitted fabric.

[0007] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the invention

[0089] Specifically:

[0091] The jacquard comb bar JK1-1, the jacquard comb bar JK1-2, the jacquard comb bar JK2-1 and the jacquard comb bar JK2-2 are respectively the second layer of yarn, the third layer of yarn, the fourth layer of yarn and the fifth layer of yarn, and the jacquard yarn guide comb bar is used to perform weft insertion movement or loop formation movement.

[0092] Reference Figure 5-6 , Figure 5 The effect of a multi-jacquard composite interlaced jacquard warp knitted fabric is applied to Figure 1 ; Figure 6 The effect of a multi-jacquard composite interlaced jacquard warp knitted fabric is applied to Figure 2 .

[0093] The jacquard bar JK1-2 follows the jacquard basic structure 1-0 / 1-1 / 1-2 / 1-1 / / , the jacquard bar JK2-1 follows the jacquard basic structure 1-2 / 1-1 / 1-0 / 1-1 / / , and the jacquard bar JK1-2 and the jacquard bar JK2-1 are used to make a loop motion by using the process of the pulling configuration. The first jacquard structure 12 is locally combined with the offset signal on the front needle bed, such as: (1-0 / 1-2)*n / (2-3 / 2-1)*m / / , (2-3 / 2-1)*m / (1-0 / 1-2)*n / / . Mesh fabrics with n, m ≥ 1, or small mesh fabrics with 1-0 / 2-3 / / , 2-3 / 1-0 / / on the front needle bed in combination with the offset signal (the effect is as follows Figure 5 , Figure 6 ), the first jacquard structure 12 produced by the jacquard electric signal deflection needle can adjust the mesh size arbitrarily according to the designer's needs.

[0094] Reference Figure 7 , Figure 7 The effect of a multi-jacquard composite interlaced jacquard warp knitted fabric is applied to Figure 3 .

[0095] The jacquard bar JK1-1 uses the jacquard basic structure 0-0 / 1-1 / 2-2 / 1-1 / / , and the jacquard bar JK2-2 uses the jacquard basic structure 2-2 / 1-1 / 0-0 / 1-1 / / . The JK1-1 and JK2-2 pull-together configuration process is used to perform weft insertion movement, and the jacquard design of the hole center line is performed on the front needle bed in combination with the offset signal (the effect is as follows Figure 7 ), using the jacquard design of the hole thread produced by the jacquard electric signal, the direction and effect of the embroidery thread in the hole can be adjusted arbitrarily according to the designer's needs.

The jacquard yarn guide bar is used to make a loop motion, and the jacquard basic structure 1-1 / 1-2 / 1-1 / 1-0 / / is used.

[0097] Ground combing bar GB8 and ground combing bar GB9 are the eighth and ninth layers of yarn respectively, and they are warp knitting plain weave 1-1 / 1-0 / 0-0 / 1-2 / / and warp knitting warp pile weave 1-1 / 2-3 / 2-2 / 1-0 / / at the bottom of the fabric on the rear needle bed. Ground combing bar GB8 and ground combing bar GB9 use two combing bars to form a circle, and combine the change of combing bar threading to weave a plain weave fabric with a warp flat and oblique weave, which has the beneficial effects of good longitudinal and transverse stability and density. With the threading design of the two-component transparent yarn, the jacquard effect of the hole center line of the front needle bed can be seen through the yarn on the rear needle bed (the back of the fabric), and the pattern effect is rich.

[0098] The plain weave fabric process can be adjusted to double warp plain, warp flat velvet, warp velvet plain structure, warp flat diagonal structure, warp diagonal flat structure, warp diagonal chain structure, single comb heavy warp structure, etc. according to design requirements. The mesh effects such as small mesh and large mesh can also be designed by changing the yarn threading of the comb bar, which has the beneficial effects of improving extensibility, physical properties, permeability, and enhancing breathability.

[0099] Compared with the traditional single / double jacquard, the traditional jacquard device emphasizes that the two half-gauge jacquards (full-gauge jacquards) are both loop-forming or weft-inserted. For example: the jacquard bar JK1-1 uses the jacquard basic structure 1-1 / 1-2 / 1-1 / 1-0 / / (loop-forming type), the jacquard bar JK1-1 uses the jacquard basic structure 1-1 / 0-0 / 1-1 / 2-2 / / (weft-inserted type); the jacquard bar JK1-2 uses the jacquard basic structure 1-1 / 1-2 / 1-1 / 1-0 / / (loop-forming type), the jacquard bar JK1-2 uses the jacquard basic structure 1-1 / 0-0 / 1-1 / 2-2 / / (weft-inserted type).

[0100] This embodiment is an upgrade based on two half-gauge Jacquards (full-gauge Jacquards) both of which are loop-forming type or weft-insertion type. The two half-gauge Jacquards (full-gauge Jacquards), one of which is loop-forming type (half-gauge) and the other of which is weft-insertion type (half-gauge), are composed of two half-gauge Jacquard combs with different configurations. For example, the jacquard comb JK1-1 has a jacquard basic structure of 1-1 / 1-2 / 1-1 / 1-0 / / (loop-forming type), and the jacquard comb JK1-1 has a jacquard basic structure of 1-1 / 0-0 / 1-1 / 2-2 / / (weft-insertion type); the jacquard comb JK1-2 has a jacquard basic structure of 1-1 / 0-0 / 1-1 / 2-2 / / (weft-insertion type), and the jacquard comb JK1-2 has a jacquard basic structure of 1-1 / 1-2 / 1-1 / 1-0 / / (loop-forming type).
