Description

Technical Field

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

[0002] Denim fabric is a coarse warp-dyed fabric with the advantages of thick texture, wear resistance, and width, and is widely used. Common denim fabrics are formed by dyeing the yarn first and then weaving. The fabric surface is simple twill plain weave, and the colors are mainly indigo, blue with black, and black. The patterns and patterns on it are usually obtained by post-printing processing, or by washing to form a gradient of light and dark colors in the same color system to give it a multi-color effect, but it is still monochrome. Printing has the problem of color fastness to washing, and the defects are more obvious during use; while washing has the defects of difficult control of the process and limited effect presentation. Summary of the invention

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

[0004] Specifically, the present application is implemented through the following scheme: A processing technology for a real denim fabric with a non-printed three-dimensional pattern, comprising a ground weave and a pattern weave. The pattern unit of the fabric comprises two groups of weft yarns, eight groups of ground weave warp yarns, and twenty-four groups of pattern weave warp yarns. The natural denim yarn is used as the ground weave warp yarn and weft yarn, and the indigo denim yarn is used as the pattern weave warp yarn, or the natural denim yarn is used as the pattern weave warp yarn and the indigo denim yarn is used as the ground weave warp yarn and weft yarn. After two groups of weft yarns, eight groups of ground warp yarns, and twenty-four groups of flower warp yarns are warped according to a certain tension, the warp yarn upper shaft is sent to the weaving link. The weaving adopts a jacquard rapier loom that can weave complex patterns and designs. According to the design, the pattern and process requirements are provided, the weft shuttle box and the color matching information, flower number, and weft density are checked, and the warp yarns in the untwisted state move regularly up and down on the heald and are introduced with the weft yarns to form cloth. Two groups of weft yarns are interwoven with eight groups of ground warp yarns to form ground texture, and two groups of weft yarns are interwoven with twenty-four groups of flower warp yarns to form flower texture. The flower texture and ground texture cooperate to form a real denim fabric with a three-dimensional pattern with a non-printing effect.

[0005] The above scheme is based on two groups of weft yarns, which cooperate with different warp yarns to form ground weave and flower weave respectively. With the help of the cooperation between the flower weave and the ground weave, and at the same time with the jacquard rapier loom that can weave complex patterns and designs, the weaving is completed. The flower effect can be formed on the fabric without printing, and the flower weave and the ground weave rely on the two groups 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.

[0006] Further, as a preference: The jacquard rapier loom adopts the Xinchang Titan TT828 model rapier loom or the Qihui 2400-needle jacquard loom to control the rise and fall of the warp threads, thereby realizing the weaving of the pattern.

[0007] Among them, the finished dyed warp beam needs to be reeded (tied), and after the sizing and dyeing of the weaving beam is completed, the warp yarns must be threaded one by one onto the dropper and the heald, and the warp beam can be used for weaving. The untwisted warp yarn is achieved through the untwisted warp-tied machine, which does not require the warp to be twisted, and the brush that comes with it marks the yarn and ties the warp in sequence.

[0008] In the ground structure of the pattern unit of the fabric, the weft yarns include the first weft and the second weft, and the positional relationship of the first weft relative to the ground warp yarns satisfies: six up, one down, and one up, and the positional relationship of the second weft relative to the ground warp yarns satisfies: 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, and 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, and then ascends to above the fifth group of ground warp yarns, and 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 flower structure of the flower unit of the fabric, the weft yarns include the first weft and the second weft, and the positional relationship of the first weft relative to the flower warp yarns satisfies: two up, six down, four up, four down, two up, one down, one up, four down, and the positional relationship of the second weft relative to the flower warp yarns satisfies: seven up, one down, seven up, one down, seven up, one down. More preferably, the first weft enters from above the first group of flower warp yarns, passes above the second group of flower warp yarns, and then descends to below the third, fourth, fifth, sixth, seventh, and eighth groups of flower warp yarns, and then ascends to above the ninth, tenth, eleventh, and twelfth groups of flower warp yarns, and then descends to below the thirteenth, fourteenth, fifteenth, and sixteenth groups of flower warp yarns, and then ascends to above the seventeenth and eighteenth groups of flower warp yarns, and then descends to below the nineteenth group of flower warp yarns, and then ascends to above the twentieth group of flower warp yarns, and finally passes below the twenty-first, twenty-second, twenty-third, and twenty-fourth groups of flower warp yarns, and then ascends to below The next cycle starts above the first group of flower organization warp yarns of a flower pattern unit; the second weft first passes over the first, second, third, fourth, fifth, sixth, and seventh groups of flower organization warp yarns, then descends to under the eighth group of flower organization warp yarns, then goes up to the ninth, tenth, eleventh, twelfth, thirteenth, fourteenth, and fifteenth groups of flower organization warp yarns, then descends to under the sixteenth group of flower organization warp yarns, then goes up to the seventeenth, eighteenth, nineteenth, twentieth, twenty-first, twenty-second, and twenty-third groups of flower organization warp yarns, and finally passes under the twenty-fourth group of flower organization warp yarns, and then goes up to the first group of flower organization warp yarns of the next flower pattern unit to start the next cycle.

[0010] During the weaving process, the warp density is set to 48 strands / cm and the weft density is set to 1Í22 strands / cm.

[0011] In the above scheme, both the warp yarn and the weft yarn are made of cotton fiber.

[0012] 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
