Description

Technical Field

[0001] The invention relates to the technical field of warp knitting, in particular to a double-jacquard single-layer multi-color gradient jacquard fabric and a manufacturing method thereof. Background Art

[0002] Traditional double jacquard warp knitted fabric is woven by double needle bed jacquard warp knitting machines. The patterns on the warp knitted fabric are usually formed by three forms: mesh structure, "V" point structure and thick and thin plain structure. Among them, when the mesh structure is used to form the pattern, the mesh holes of the front and back layers can be overlapped together, that is, a perforated effect, or the mesh holes can be made on only one side to form a non-perforated effect. However, the mesh holes on the same side have only one color, the fabric structure is relatively simple, and the pattern form is relatively single. In addition, since double jacquard warp knitting machines are all double needle beds, they weave mostly double-sided fabrics, and the resulting fabrics are relatively thick. Furthermore, gradient color fabrics woven by double jacquard warp knitting machines are gradually becoming popular, but the gradient pattern formed in the prior art has poor clarity at the gradient point, and the resulting fabric gradient effect is not good, affecting the quality of the fabric. Summary of the invention

[0003] In view of this, as a first aspect of the present invention, a double jacquard single-layer multi-color gradient jacquard fabric is proposed, the knitting yarn of the fabric includes a loop-forming solid color area and a point-forming area, and the loop-forming solid color area includes the following yarns and tissues:

[0004] The first yarn and its threading ground comb GB1 form a chain structure 1-1-1-0 / 0-0-0-1 / / ;

[0005] The second yarn is threaded through a half-gauge jacquard bar JB2.1, and the third yarn is threaded through a half-gauge jacquard bar JB2.2. One of the two half-gauge jacquard bars forms a heavy warp structure 1-1-2-0 / 1-1-1-3 / / ; the other forms a weft insertion structure;

[0006] The fourth yarn and the half-number jacquard bars JB3.1 and JB3.2 through which the fourth yarn is threaded to form the weft insertion structure;

[0007] And the fifth yarn and its threading ground comb GB4 and the formed warp plain structure 2-2-2-3 / 1-1-1-0 / / ;

[0008] The first yarn and the fifth yarn are transparent yarns, the second yarn and the third yarn have different yarn characteristics, and the fourth yarn has the same yarn characteristics as the second yarn or the third yarn;

[0009] The yarn in the point-raising area is the same as the yarn in the loop-forming solid color area, and its organization includes:

[0010] The first yarn forms a chain weave structure of 1-1-1-0 / 0-0-0-1 / / ; the second yarn or the third yarn forms a chain weave structure of 1-1-2-1 / 1-1-1-2 / / , and the other is a weft insertion structure; the fourth yarn forms a weft insertion structure and the fifth yarn forms a warp plain structure of 2-2-2-3 / 1-1-1-0 / / ;

[0011] In the loop solid color area and the point raising area, the yarns are woven only on the front needle bed or the rear needle bed; the heavy warp structure or chain structure formed by the second yarn and the third yarn is located above the chain structure formed by the first yarn and the warp plain structure formed by the fifth yarn; the weft insertion structure is located below the chain structure formed by the first yarn and the warp plain structure formed by the fifth yarn.

[0012] Further, the weft inlay structure formed by the fourth yarn includes at least one of a one-needle weft inlay structure 1-1-1-1 / 2-2-2-2 / / , a two-needle weft inlay structure 0-0-0-0 / 2-2-2-2 / / and 1-1-1-1 / 3-3-3-3 / / , and a three-needle weft inlay structure 0-0-0-0 / 3-3-3-3 / / .

[0013] Furthermore, the fabric also includes a full weft inlay area, the knitting yarn of the full weft inlay area is the same as the yarn of the loop-forming solid color area, and its organization includes:

[0015] Furthermore, the yarn characteristics include color or type. When the woven yarn is white yarn and needs to be dyed after weaving, the yarn characteristic can be the type, and the color formed after the dyeing process is different; when the woven yarn is colored yarn, the yarn characteristic can be the color, and the types can be the same or different. The two-color gradient effect of the present invention is that in the finished fabric after the dyeing or shaping process, the second yarn and the third yarn present different colors, and the fourth yarn presents the same color as the third yarn or the second yarn.

[0016] Furthermore, the second yarn is a cationic polyester DTY yarn, and the third yarn is a polyester low-elastic DTY yarn.

[0063] (5) Finishing: Dyeing or shaping of fabrics after weaving. Fabrics woven from white yarn need to go through dyeing, while fabrics woven from colored yarn need to go through washing and shaping.

[0064] Example 2

[0067] In the weaving of (4) in the full weft insertion area, the half-gauge jacquard bars JB2.1 and JB2.2 both have weft insertion structures on the rear needle bed. The weft insertion structures of the half-gauge jacquard bars JB2.1 and JB2.2 are one-needle weft insertion structures 1-1-1-1 / 1-1-2-2 / / .

[0068] In the above embodiment, the yarn feature is the type of yarn, and the colors after dyeing are different. In addition, the yarn feature can also be the color of the yarn. For example, the second yarn and the third yarn are both polyester DTY colored spun yarns, but they have different colors and only need to be washed after weaving.

The 6 combs are all knitted into loops on the front needle bed or the rear needle bed; (3) Yarn threading: the ground comb GB1 fully threads the first yarn; the half-gauge jacquard comb JB2.1 threads the second yarn; the half-gauge jacquard comb JB2.2 threads the third yarn; the half-gauge jacquard combs JB3.1 and JB3.2 fully thread the fourth yarn; the ground comb GB4 threads the fifth yarn; the first yarn and the fifth yarn are transparent yarns, the second yarn and the third yarn have different yarn characteristics; the fourth yarn and the second yarn or the third yarn are the same yarn; (4) Weaving: Ground bar GB1 forms loops on the needle bed, weaving 1-1-1-0 / 0-0-0-1 / / chain weave; half-gauge jacquard bar JB2.1 selectively forms loops on the needle bed, weaving 1-1-2-0 / 1-1-1-3 / / heavy warp weave in the looped solid color area, and 1-1-2-1 / 1-1-1-2 / / chain weave in the raised point area, forming one color of the fabric; half-gauge jacquard bar JB2.

2. Selectively pad yarn on the needle bed to form loops, wherein 1-1-2-0 / 1-1-1-3 / / heavy warp tissue is knitted in the loop solid color area, and 1-1-2-1 / 1-1-1-2 / / chain tissue is knitted in the point area to form another color of the fabric; half-gauge jacquard bars JB3.1 and JB3.2 knit weft insertion tissue on the needle bed to form jacquard mesh; ground bar GB4 knits 2-2-2-3 / 1-1-1-0 / / warp plain tissue on the needle bed; (5) Finishing: Dyeing or shaping process of fabric after weaving.

6. The method for making a double jacquard single-layer multi-color gradient jacquard fabric according to claim 5, characterized in that: The fabric also includes a full weft inlay area. In the weaving of the full weft inlay area, the half-gauge jacquard bars JB2.1 and JB2.2 both have weft inlay structures on the needle bed.

7. The method for making a double jacquard single-layer multi-color gradient jacquard fabric according to claim 5, characterized in that: The weft insertion structure of the half-gauge jacquard bars JB3.1 and JB3.2 includes at least one of the one-needle weft insertion structure 1-1-1-1 / 2-2-2-2 / / , the two-needle weft insertion structure 0-0-0-0 / 2-2-2-2 / / and 1-1-1-1 / 3-3-3-3 / / and the three-needle weft insertion structure 0-0-0-0 / 3-3-3-3 / / .

8. The method for making a double jacquard single-layer multi-color gradient jacquard fabric according to claim 5, characterized in that: The weft insertion structure of the half-gauge jacquard bars JB2.1 and JB2.2 includes a one-needle weft insertion structure 1-1-1-1 / 1-1-2-2 / / .
