Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and particularly to a weft knitting structure combining jacquard and mesh, and a knitting method thereof. Background Art

[0002] The fashion trend of weft knitted fabrics is a constantly changing field. With the increasing demand for comfort and functionality, weft knitted fabrics are constantly pursuing higher comfort and practicality. This includes a soft handfeel, natural stretchability and adaptability, as well as fabrics suitable for various climate conditions. In addition, designers and brands often use weft knitting technology to create unique textures and patterns to attract consumers. This involves complex knitting structures, three-dimensional effects and artistic designs.

[0003] However, there are the following problems in simultaneously achieving mesh and jacquard effects on a single-sided weft knitting machine: at the jacquard part, the ground yarn and the jacquard yarn do not loop and form float lines, but at the mesh part, the ground yarn loops completely and the jacquard yarn forms a float line. Therefore, it is very unreasonable to knit mesh and jacquard simultaneously. Therefore, it is necessary to develop a weft knitting structure combining jacquard and mesh, and to consider the definition methods of "jacquard" and "mesh" in the machine process and the circular knitting machine configuration scheme. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a weft knitting structure combining jacquard and mesh, and at the same time to provide a knitting method combining jacquard and mesh.

[0006] To achieve the above technical purposes and reach the above technical effects, the present invention is realized through the following technical solutions:

[0007] A weft knitting structure combining jacquard and mesh, the weft knitting structure includes a weft knitting structure body formed by looping both the ground yarn and the pattern yarn, the weft knitting structure body is provided with jacquard and mesh, the ground yarn and the pattern yarn of the jacquard do not loop and form double float lines of the ground yarn and the pattern yarn, and the ground yarn of the mesh loops completely to form loops and the pattern yarn does not loop to form a pattern yarn float line.

[0008] Among them, the ground yarn uses polyester low elastic yarn with a specification of 75D / 72F.

[0009] Among them, the pattern yarn uses polyester-ammonia empty package semi-dull yarn with a specification of E20D+PD50D / 72F.

[0010] Among them, the mass ratio of the ground yarn in the weft knitting structure is 57% - 58%, and the total mass ratio of the fancy yarn and the ground yarn in the weft knitting structure is 100%.

[0011] A weft knitting method combining jacquard and mesh includes the following steps:

[0012] S1. Determine the color numbers of the jacquard and mesh effects in the Pattern Edit software, set the working mode of the electromagnetic needle selector at the corresponding position in the Paint Knit software, and determine the knitting cam matching scheme in cooperation with the electromagnetic needle selector;

[0013] S2. Determine the raw material matching scheme of the pattern. The ground yarn uses polyester low elastic yarn, and the fancy yarn uses polyester - ammonia air - covered semi - dull yarn;

[0014] S3. Determine the machine - setting parameters of the process according to the machine startup situation and the fabric surface effect. Set the tension of the ground yarn to 5 - 7 g, the tension of the fancy yarn to 3 g, the ratio of the pulling and curling base teeth to 80:20, the pulling and winding disc value to 34, the feeding amount of the ground yarn to 26 - 27 cm, the feeding amount of the fancy yarn to 28 - 29 cm, and the pressing needle depth to 11;

[0015] S4. Conduct multiple small - sample trial weavings for this pattern to determine the machine - setting density. The warp density of the weft knitting structure is 32 ± 0.1 pieces / cm, and the weft density of the weft knitting structure is 48 ± 0.1 pieces / cm;

[0016] S5. Conduct large - sample weaving for this pattern to determine the quality indicators. The meter weight of the weft knitting structure is 195 g / ㎡ - 196 g / ㎡, the weft - wise shrinkage rate of the weft knitting structure is 33% - 34%, the flower height of the jacquard on the weft knitting structure is 17% cm - 17.5 cm, the flower width of the jacquard on the weft knitting structure is 41 cm - 42 cm, the degreased flower height shrinkage rate of the jacquard on the weft knitting structure is 94% - 95%, and the degreased flower width shrinkage rate of the jacquard on the weft knitting structure is 101% - 102%.

[0017] Preferably, in step S1, the determination of the color numbers of the jacquard and mesh effects in the Pattern Edit software is specifically as follows: the body of the weft knitting structure is color number 1, the mesh is color number 2, and the jacquard is color number 3.

[0018] Preferably, in step S1, the working mode of the electromagnetic needle selector is specifically as follows: each loop system of the 32 - way single - side weft knitting machine is controlled by electromagnet one for controlling the ground yarn needle - out and electromagnet two for controlling the fancy yarn needle - out. When knitting the body of the weft knitting structure, electromagnet one controls the ground yarn needle - out and electromagnet two controls the fancy yarn needle - out. When knitting the jacquard, electromagnet one controls the ground yarn not to needle - out and electromagnet two controls the fancy yarn not to needle - out.

Jacquard and mesh are provided on the weft knitting fabric body. For the jacquard, neither the ground yarn nor the pattern yarn forms a loop, resulting in double floats of the ground yarn and the pattern yarn.

[0031] Set the working mode of the electromechanical needle selector at the corresponding position in the PaintKnit software. The working mode of the electromechanical needle selector is specifically as follows: Each loop-forming system of a 32-course single-sided weft knitting machine is controlled by an electromagnet 1 for controlling the ground yarn to emerge from the needle and an electromagnet 2 for controlling the fancy yarn to emerge from the needle. When knitting the weft knitting fabric body, electromagnet 1 controls the ground yarn to emerge from the needle and electromagnet 2 controls the fancy yarn to emerge from the needle. When knitting the jacquard, electromagnet 1 controls the ground yarn not to emerge from the needle and electromagnet 2 controls the fancy yarn not to emerge from the needle. When knitting the mesh, electromagnet 1 controls the ground yarn to emerge from the needle and electromagnet 2 controls the fancy yarn not to emerge from the needle;

[0032] Determine the knitting cam matching scheme in cooperation with the electromechanical needle selector. As Figure 2 shown, the knitting cam matching scheme specifically includes a first knitting cam 4 and a second knitting cam 5. The first knitting cam 4 forms loops of the ground yarn by controlling the knitting needles to move along the rising trajectory, and the second knitting cam 5 forms loops of the fancy yarn by controlling the knitting needles to move along the rising trajectory;

[0033] S2. Determine the raw material matching scheme of the pattern. The ground yarn uses polyester low elastic yarn, and the fancy yarn uses polyester-ammonia air-covered semi-dull yarn;

[0036] S5. Conduct large-sample weaving on this pattern to determine the quality indexes. The gram weight per meter of the weft knitting fabric is 195.79 g / ㎡, the weftwise shrinkage rate of the weft knitting fabric is 33.38%, the height of the jacquard on the weft knitting fabric is 17.20 cm, the width of the jacquard on the weft knitting fabric is 41.80 cm, the shrinkage rate of the degreased jacquard height on the weft knitting fabric is 94.19%, and the shrinkage rate of the degreased jacquard width on the weft knitting fabric is 101.67%.

[0037] By setting the working mode of the electromagnetic selector of the single-sided weft knitting machine and the matching scheme of knitting cams, the knitting structure in which the ground yarn and the fancy yarn on the weft knitting fabric body form floats is controlled to form jacquard and mesh effects on the weft knitting fabric body, and the limitation of the types of weavable tissues of the single-sided weft knitting machine is broken through; meanwhile, the novel weft knitting fabric and its knitting method provided by the present invention can freely design mesh and jacquard effects, and designers and brands will not be restricted, creating unique textures and patterns, which promotes the diversified development of weft knitting products.
