Description

Technical Field

[0001] The present application relates to a genuine denim fabric with a non-printed three-dimensional pattern, belonging to the technical field of special textiles. Background Art

[0002] Denim is a coarse, yarn-dyed, warp-faced fabric with advantages such as a thick texture, wear resistance, and a strong, wide texture, making it a common fabric. Common denim fabrics are typically woven using a simple twill weave, primarily in indigo, blue-on-black, and black. Patterns and designs are typically applied through post-printing processing, or through washing to create a multi-color effect with a gradient of light and dark shades within the same color scheme, while the fabric itself remains a single color. Printing can have issues with wash fastness, making defects more noticeable during use; washing, on the other hand, has drawbacks such as difficult process control and limited ways to achieve the desired effect. Utility Model Content

[0003] In view of this, the present application provides a real denim fabric with a non-printed three-dimensional pattern. With the help of the coordination of the warp and weft structures, the fabric can be given a three-dimensional pattern effect without post-processing, avoiding dyeing treatment, so that the overall fabric has the characteristics of real denim, and there is no defect of poor color fastness.

[0004] Specifically, this application is implemented through the following solutions:

[0005] A real denim fabric with a non-printed three-dimensional pattern comprises a ground weave and a floral weave. The floral unit of the fabric comprises two groups of weft yarns, eight groups of ground weave warp yarns, and twenty-four groups of floral weave warp yarns. Natural denim yarns are used as the ground weave warp and weft yarns, and indigo denim yarns are used as the floral weave warp yarns. Alternatively, natural denim yarns are used as the floral weave warp yarns, and indigo denim yarns are used as the ground weave warp and weft yarns. The two groups of weft yarns are interwoven with the eight groups of ground weave warp yarns to form the ground weave, and the two groups of weft yarns are interwoven with the twenty-four groups of floral weave warp yarns to form the floral weave. The floral weave and the ground weave cooperate to form a real denim fabric with a three-dimensional pattern having a non-printed effect.

[0006] The above scheme is based on two sets of weft yarns, which are combined with different warp yarns to form the ground weave and flower weave respectively. With the help of the cooperation between the flower weave and the ground weave, a flower pattern effect can be formed on the fabric without printing, and the flower weave and the ground weave rely on the two sets of weft yarns to achieve different structures to achieve a three-dimensional effect. There is no color fastness problem existing in operations such as dyeing and printing. With the help of this structure and the setting of different colors, the warp and weft are interwoven to achieve a color-woven effect, which is why it is called real denim; compared with the three-dimensional effect of conventional cutting methods, while ensuring the three-dimensional effect, the flower weave and the ground weave structure are integrated, the surface structure is relatively flat, no additional post-processing is required, and the process is simple.

[0007] Furthermore, as a preference:

[0008] In the ground structure of the pattern unit of the fabric, the weft yarns include a first weft and a second weft, and the positional relationship of the first weft relative to the ground warp yarns satisfies the following: six up, one down, and one up; the positional relationship of the second weft relative to the ground warp yarns satisfies the following: one up, three down, one up, and three down. More preferably, the first weft enters from above the first group of ground warp yarns, passes through the second, third, fourth, fifth, and sixth groups of ground warp yarns in sequence, descends to below the seventh group of ground warp yarns, then ascends to above the eighth group of ground warp yarns, and then ascends to above the first group of ground warp yarns of the next ground unit to start the next cycle; the second weft enters from above the first group of ground warp yarns, first descends to below the second, third, and fourth groups of ground warp yarns, then ascends to above the fifth group of ground warp yarns, then descends to below the sixth, seventh, and eighth groups of ground warp yarns, and then ascends to above the first group of ground warp yarns of the next ground unit to start the next cycle.

[0009] In the pattern structure of the pattern unit of the fabric, the weft yarns include a first weft and a second weft. The positional relationship of the first weft relative to the pattern warp yarns satisfies the following: two up, six down, four up, four down, two up, one down, one up, four down. The positional relationship of the second weft relative to the pattern warp yarns satisfies the following: seven up, one down, seven up, one down. More preferably, the first weft enters from above the first group of pattern warp yarns, passes above the second group of pattern warp yarns, then descends to below the third, fourth, fifth, sixth, seventh, and eighth groups of pattern warp yarns, then ascends to above the ninth, tenth, eleventh, and twelfth groups of pattern warp yarns, then descends to below the thirteenth, fourteenth, fifteenth, and sixteenth groups of pattern warp yarns, then ascends to above the seventeenth and eighteenth groups of pattern warp yarns, then descends to below the nineteenth group of pattern warp yarns, then ascends to above the twentieth group of pattern warp yarns, and finally passes below the twenty-first, twenty-second, twenty-third, and twenty-fourth groups of pattern warp yarns, then ascends to below The next cycle starts above the first group of pattern warp yarns in a pattern unit; the second weft first passes over the first, second, third, fourth, fifth, sixth and seventh groups of pattern warp yarns, then descends under the eighth group of pattern warp yarns, then ascends over the ninth, tenth, eleventh, twelfth, thirteenth, fourteenth and fifteenth groups of pattern warp yarns, then descends under the sixteenth group of pattern warp yarns, then ascends over the seventeenth, eighteenth, nineteenth, twentieth, twenty-first, twenty-second and twenty-third groups of pattern warp yarns, and finally passes under the twenty-fourth group of pattern warp yarns, and then ascends over the first group of pattern warp yarns in the next pattern unit to start the next cycle.

[0010] In the above scheme, both the warp yarn and the weft yarn are made of cotton fiber.

[0011] By adopting the above-mentioned solution of the present application, it is possible to impart patterns on real denim fabrics without post-processing such as printing. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the technical solutions in the embodiments of this application will be further described in detail below in conjunction with the drawings in the embodiments of this application. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit the technical solutions of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0017] In addition, the terms "first" and "second" are used only for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly specifying the number of technical features. "Multiple" means two or more, unless otherwise specifically defined.

[0018] The present application provides a genuine denim fabric with a non-printed three-dimensional pattern, using natural color 22S / 2 cotton fiber as the first weft 1 and the second weft 2, natural color 32S / 2 cotton fiber as the ground weft yarn 3, and indigo 32S / 2 cotton fiber as the pattern weft warp yarn 4; the first weft 1 and the second weft 2 are respectively interwoven with the ground weft warp yarn 3 to form the ground weave, and the first weft 1 and the second weft 2 are respectively interwoven with the pattern weft warp yarn 4 to form the pattern weave, and the pattern weave and the ground weave cooperate to achieve a structural three-dimensional pattern effect on the fabric that is not printed or dyed.

[0019] Specifically, the weft yarns (first weft 1, second weft 2) and warp yarns (ground warp yarn 3, pattern warp yarn 4) are warped according to a certain tension, then the warp yarns are dyed (such as indigo dyeing), sized, and put on the warp beam before being sent to the weaving process. Because it is a real denim fabric with non-printed three-dimensional patterns, it needs to be interwoven, and the pattern is large, which is difficult to achieve with a plain machine. In this case, a jacquard rapier loom that can weave complex patterns and designs is used (such as: Xinchang Titan TT828 model rapier loom, Qihui 2400-needle jacquard loom) to control the rise and fall of the warp threads, thereby realizing the weaving of the pattern.

[0020] The finished, dyed warp beams need to be reeded (tied). After the sizing and dyeing of the weaving beams is complete, the warp yarns must be threaded individually onto the drop wires and healds before the warp beams can be used for weaving. The warp yarns on the sizing beams are in an untwisted state (a twist-free warp-tied machine). The pattern is provided according to the design, and the weft shuttle box, color matching information, pattern number, and weft density are verified according to process requirements. The warp yarns on the weaving beams move regularly up and down the healds, interweaving with the weft yarns to form the fabric.

[0021] Process control of weaving process such as Figure 1 、 Figure 2 As shown:

[0022] Combine Figure 1 The ground warp yarn 3 includes eight groups. The positional relationships of the first weft 1 and the second weft 2 relative to the eight groups of ground warp yarns 3 respectively satisfy "six up, one down, one up" and "one up, three down, one up, three down", that is, the first weft 1 enters from above the ground warp yarn 1 301, passes through the ground warp yarn 2 302, the ground warp yarn 3 303, the ground warp yarn 4 304, the ground warp yarn 5 305, and the ground warp yarn 6 306 in sequence, then descends to below the ground warp yarn 7 307, and then ascends to above the ground warp yarn 8 308, completing the interweaving of the ground warp yarn 3 and the first weft 1 in the cycle. Then it goes up to the first group of ground weave warp yarns of the next ground weave unit to start the next cycle; the second weft 2 enters from above the ground warp yarn 1 301, first descends to below the ground warp yarn 2 302, the ground warp yarn 3 303, and the ground warp yarn 4 304, then goes up to above the ground warp yarn 5 305, and then descends to below the ground warp yarn 6 306, the ground warp yarn 7 307, and the ground warp yarn 8 308. After completing the interweaving of the ground weave warp yarn 3 and the second weft 2 in this cycle, it goes up to the first group of ground weave warp yarns of the next ground weave unit to start the next cycle.

[0023] Combine Figure 2 The flower warp yarns 4 include twenty-four groups. The positional relationships of the first weft 1 and the second weft 2 relative to the twenty-four groups of flower warp yarns 4 respectively satisfy "two up, six down, four up, four down, two up, one down, one up, four down" and "seven up, one down, seven up, one down, seven up, one down, one up, three down, three down", that is: the first weft 1 enters from above the flower warp yarn 1 401, passes over the flower warp yarn 2 402, and then goes down to below the flower warp yarn 3 403, the flower warp yarn 404, the flower warp yarn 5 405, the flower warp yarn 6 406, the flower warp yarn 7 407, and the flower warp yarn 8 408, and then goes up to Flower warp yarn 9 409, flower warp yarn 10 410, flower warp yarn 11 411, flower warp yarn 12 412, then go down to flower warp yarn 13 413, flower warp yarn 14 414, flower warp yarn 15 415, flower warp yarn 16 416, then go up to flower warp yarn 17 417, flower warp yarn 18 418, then go down to flower warp yarn 19 419, then go up to flower warp yarn 20 420, and finally go to flower warp yarn 21 421, flower warp yarn 22 422, flower warp yarn 23 423, flower warp yarn 24 424 4, after completing the interweaving of the flower structure warp yarn 4 and the first weft 1 in this cycle, it goes up to the top of the first group of flower structure warp yarns of the next pattern unit to start the next cycle; the second weft first passes over the flower warp yarn 1 401, the flower warp yarn 2 402, the flower warp yarn 3 403, the flower warp yarn 4 404, the flower warp yarn 5 405, the flower warp yarn 6 406, and the flower warp yarn 7 407, then goes down to the bottom of the flower warp yarn 8 408, and then goes up to the flower warp yarn 9 409, the flower warp yarn 10 410, the flower warp yarn 11 411, the flower warp yarn 12 412, and the flower warp yarn 13 413, above the flower warp yarn fourteen 414, and flower warp yarn fifteen 415, then descend to below the flower warp yarn sixteen 416, then ascend to above the flower warp yarn seventeen 417, flower warp yarn eighteen 418, flower warp yarn nineteen 419, flower warp yarn twenty 420, flower warp yarn twenty-one 421, flower warp yarn twenty-two 422, and flower warp yarn twenty-three 423, and finally below the flower warp yarn twenty-four 424, completing the interweaving of the flower structure warp yarn 4 and the second weft 2 in this cycle, and then ascend to above the first group of flower structure warp yarns of the next pattern unit to start the next cycle.

[0024] The weaving warp density is 48 threads / cm, the weft density is 1╳22 threads / cm, and each tissue unit contains four patterns to obtain real denim fabric.

[0025] The above scheme is based on two sets of weft yarns, which are combined with different warp yarns to form the ground weave and flower weave respectively. With the help of the cooperation between the flower weave and the ground weave, a flower pattern effect can be formed on the fabric without printing, and the flower weave and the ground weave rely on the two sets of weft yarns to achieve different structures to achieve a three-dimensional effect. There is no color fastness problem existing in operations such as dyeing and printing. With the help of this structure and the setting of different colors, the warp and weft are interwoven to achieve a color-woven effect, which is why it is called real denim; compared with the three-dimensional effect of conventional cutting methods, while ensuring the three-dimensional effect, the flower weave and the ground weave structure are integrated, the surface structure is relatively flat, no additional post-processing is required, and the process is simple.
