Description

Technical Field

[0001] This invention relates to jacquard fabrics, and more particularly to a weaving method for a double-sided, different-patterned, color-woven jacquard fabric, belonging to the field of textile fabric technology. Background Technology

[0002] Jacquard fabrics are considered high-end products in the textile industry, and yarn-dyed jacquard fabrics are even more irresistible. In fact, embroidered fabrics and others can compete with and rival yarn-dyed jacquard fabrics. However, embroidered fabrics are expensive, and there is a desire for fabrics that are more beautiful than existing yarn-dyed jacquard fabrics, yet similar in appearance to embroidered fabrics, and at a lower price. Summary of the Invention

[0003] The purpose of this invention is to provide a weaving method for a double-sided, differently patterned yarn-dyed jacquard fabric. This method, developed through repeated trials in response to market demand, has exceeded expectations, resembling not only embroidery but also double-sided embroidery. This transforms existing yarn-dyed jacquard fabrics into double-sided, differently patterned yarn-dyed jacquard fabrics.

[0004] To solve the above-mentioned technical problems, the objective of this invention is achieved as follows:

[0005] The present invention relates to a method for weaving a double-sided patterned jacquard fabric, wherein the double-sided patterned jacquard fabric is woven on a double-shed jacquard velvet loom by interlacing base fabric warp yarns, surface patterned warp yarns, inner patterned warp yarns, base fabric surface weft yarns, and base fabric inner weft yarns.

[0006] The base fabric warp yarns include a first base fabric ground warp yarn and a second base fabric ground warp yarn; the surface patterned warp yarns have colors required according to the pattern design, including the first surface patterned warp yarn to the nth surface patterned warp yarn; the inner patterned warp yarns have colors required according to the pattern design, including the first inner patterned warp yarn to the nth inner patterned warp yarn; the base fabric surface weft yarns include the first surface weft yarn to the nth surface weft yarn according to the weave structure cycle; the base fabric inner layer weft yarns include the first inner weft yarn to the nth inner weft yarn according to the weave structure cycle.

[0007] The base fabric warp yarns are interwoven with the base fabric surface weft yarns and the base fabric inner layer weft yarns to form the base fabric; the surface patterned warp yarns are interwoven with the base fabric surface weft yarns to form the surface jacquard fabric; and the inner patterned warp yarns are interwoven with the base fabric inner layer weft yarns to form the inner jacquard fabric.

[0008] The weaving method includes the following steps:

[0009] Step 1: Yarn preparation:

[0010] The yarn is dyed according to the color requirements of the designed jacquard pattern;

[0011] Step 2, Warping:

[0012] The first ground warp yarn and the second ground warp yarn of the base fabric are arranged in sequence and warped onto a single warp beam;

[0013] Arrange the first to nth surface warp threads sequentially on a single warp beam;

[0014] Arrange the first to nth inner layer warp threads in sequence and place them on a single warp beam.

[0015] Step 3: Threading the heddles and inserting the reeds:

[0016] The first ground warp yarn of the base fabric, the first pattern warp yarn of the outer layer, the first pattern warp yarn of the inner layer, the second ground warp yarn of the base fabric, the nth pattern warp yarn of the outer layer, and the nth pattern warp yarn of the inner layer are arranged in sequence and threaded into the pile warp heddles in the double shed rapier loom, and the reed is inserted according to the warp density requirements; the pile warp heddles have three working positions: upper, middle, and lower.

[0017] Step 4: Heddle raising and weft insertion weaving:

[0018] The upper and lower rapiers of the double-shed rapier loom sequentially feed the first weft yarn of the outer layer, the first weft yarn of the inner layer, the nth weft yarn of the outer layer, and the nth weft yarn of the inner layer. At this time, the first ground warp yarn and the second ground warp yarn of the base fabric interweave with the outer weft yarn and the inner weft yarn of the base fabric according to the openings formed by the upper working position, the lower working position, and the lower working position and the upper working position to form the base fabric.

[0019] The surface layer warp yarns from the first to the nth pattern are interwoven with the base fabric surface weft yarns according to the pattern design and the openings formed by the upper and middle working positions to form the surface jacquard fabric. The surface pattern warp yarns that are not shown in the pattern are in the middle working position and are hidden between the base fabric surface weft yarns and the base fabric inner weft yarns.

[0020] The inner layer first warp to the inner layer nth warp are interwoven with the base fabric weft yarn according to the pattern design and the opening formed by the middle working position and the lower working position to form the inner layer jacquard fabric. The inner layer pattern warp yarns that are not shown in the pattern are in the middle working position and are hidden between the base fabric surface weft yarns and the base fabric weft yarns.

[0021] Step 5: Post-processing.

[0022] Based on the above scheme and as a preferred option: in the fourth step, the surface patterned warp yarns are interwoven with the base layer weft yarns, and the surface patterned warp yarns are woven from the upper, middle, upper, middle working positions to the opening formed by the upper, middle, lower, middle, lower, middle working positions.

[0023] Based on the above scheme and as a preferred option: in the fourth step, the inner patterned warp yarns are interwoven with the outer layer weft yarns of the base fabric, and the inner patterned warp yarns are woven from the working positions of lower, middle, lower, middle to the opening formed by the working positions of lower, middle, upper, middle, upper, middle.

[0024] Based on the above scheme and as a preferred option: in the fourth step, the first to nth warp threads of the surface layer are woven with the weft yarns of the base fabric in a two-up-one-middle, three-up-one-middle, or four-up-one-middle pattern to form an opening.

[0025] Based on the above scheme and as a preferred option: in the fourth step, the inner layer first warp to the inner layer nth warp are woven with the base layer weft yarn in a two-down-one-middle, three-down-one-middle, or four-down-one-middle weave to form an opening.

[0026] The beneficial effects of this invention are as follows: The weaving method for a double-sided jacquard fabric with different patterns involved in this invention is achieved through a single-pass weaving process using a double-shed jacquard velvet loom, resulting in high efficiency. The outer and inner jacquard fabrics are relatively independent, resembling double-sided embroidery, and possess a unique and eye-catching style. Furthermore, during jacquard weaving, the patterned warp yarns are entirely hidden in the middle of the base fabric, resulting in a clean fabric surface and eliminating the need to remove floating threads on the reverse side, as is required for large jacquard fabrics.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Combination Figure 1 , Figure 2 and Figure 3The present invention will be described in detail below. The present invention relates to a method for weaving a double-sided patterned jacquard fabric, wherein the double-sided patterned jacquard fabric is woven on a double-shed jacquard velvet loom by interlacing base fabric warp yarns, surface patterned warp yarns, inner patterned warp yarns, base fabric surface weft yarns, and base fabric inner weft yarns.

[0033] The base fabric warp yarns include a first base fabric ground warp yarn RT1 and a second base fabric ground warp yarn RT2; the surface patterned warp yarns have colors required according to the pattern design, including the first surface patterned warp R1 to the nth surface patterned warp Rn; the inner patterned warp yarns have colors required according to the pattern design, including the first inner patterned warp R1 to the nth inner patterned warp Rn; the base fabric surface weft yarns, according to the weave structure cycle, include the first surface weft yarn W1 to the nth surface weft yarn W1; the base fabric inner layer weft yarns, according to the weave structure cycle, include the first inner weft yarn W1 to the nth inner weft yarn Wn.

[0034] The base fabric warp yarns are interwoven with the base fabric surface weft yarns and the base fabric inner layer weft yarns to form the base fabric; the surface patterned warp yarns are interwoven with the base fabric surface weft yarns to form the surface jacquard fabric; and the inner patterned warp yarns are interwoven with the base fabric inner layer weft yarns to form the inner jacquard fabric.

[0035] The weaving method includes the following steps:

[0036] Step 1: Yarn preparation:

[0037] The yarn needs to be dyed according to the color requirements of the designed jacquard pattern.

[0038] Step 2, Warping:

[0039] The first and second ground warp yarns of the base fabric are arranged in sequence and warped onto a single warp beam.

[0040] Arrange the first to nth warp patterns of the surface layer in sequence and place them on a single warp beam.

[0041] Arrange the first to nth warp patterns of the inner layer in sequence and place them on a single warp beam.

[0042] Step 3: Threading the heddles and inserting the reeds:

[0043] The first ground warp yarn of the base fabric, the first pattern warp yarn of the outer layer, the first pattern warp yarn of the inner layer, the second ground warp yarn of the base fabric, the nth pattern warp yarn of the outer layer, and the nth pattern warp yarn of the inner layer are sequentially threaded into the pile warp heddles of the double shed rapier loom, and the reeds are inserted according to the process requirements. The pile warp heddles have three working positions: upper, middle, and lower. The warp yarns in the upper working position can interweave with the weft yarns fed into the upper rapier to form the outer fabric, and the warp yarns in the lower working position can interweave with the weft yarns fed into the lower rapier to form the inner fabric. If the warp yarns are in the middle working position, they do not participate in the interweaving of the outer and inner fabrics; they are located in the middle of the outer and inner fabrics and are not exposed. Threading all the warp yarns into the pile heddles allows all the warp yarns to participate in the interweaving of the outer and inner fabrics.

[0044] Step 4: Heddle raising and weft insertion weaving:

[0045] The upper and lower rapiers of the double-shed rapier loom sequentially feed the first weft yarn of the outer layer, the first weft yarn of the inner layer, the nth weft yarn of the outer layer, and the nth weft yarn of the inner layer. At this time, the first ground warp yarn and the second ground warp yarn of the base fabric interweave with the outer weft yarn and the inner weft yarn of the base fabric according to the openings formed by the upper working position, the lower working position, and the lower working position and the upper working position to form the base fabric.

[0046] The surface layer warp yarns from the first to the nth pattern are interwoven with the base fabric surface weft yarns according to the pattern design, forming openings at the upper and middle working positions to create the surface jacquard fabric. Surface pattern warp yarns not shown in the pattern are in the middle working position during interweaving and do not participate in the fabric interweaving. Hidden between the base fabric surface weft yarns and the base fabric inner weft yarns, the surface layer warp yarns from the first to the nth pattern are woven with the base fabric surface weft yarns using a two-up-one-middle, three-up-one-middle, or four-up-one-middle weft structure.

[0047] The inner layer, from the first to the nth warp, interweaves with the base layer weft yarns according to the pattern design, forming openings at the middle and lower working positions to create the inner layer fabric. The inner layer warp yarns not shown in the pattern are in the middle working position and do not participate in the interweaving of the main fabric. They are hidden between the base fabric surface weft yarns and the base layer weft yarns. The inner layer warp yarns from the first to the nth warp are woven with the base layer weft yarns using a two-one-middle, three-one-middle, or four-one-middle weft structure.

[0048] Step 5: Post-processing.

[0049] In one embodiment of the present invention, the outer layer weft yarn of the base fabric includes a first outer layer weft yarn, a second outer layer weft yarn to a 24th outer layer weft yarn, and the inner layer weft yarn of the base fabric includes an inner layer first weft yarn, an inner layer second weft yarn to a 24th outer layer weft yarn; that is, in this embodiment, n is 24. Figure 2In the design, the outer layer weft yarns of the base fabric are numbered 1, 2 to 24, representing the first, second, and 24th weft yarns of the outer layer. Similarly, the inner layer weft yarns of the base fabric are also numbered 1, 2 to 24, representing the first, second, and 24th weft yarns of the inner layer.

[0050] As another embodiment of the present invention, such as Figure 3 As shown, in the fourth step, the surface patterned warp yarns can also be interwoven with the base fabric's surface weft yarns, with the surface patterned warp yarns changing from the upper, middle, upper, middle working position to the upper, middle, lower, middle, lower, middle working position for weaving. Similarly, the inner patterned warp yarns can also be interwoven with the base fabric's surface weft yarns, with the inner patterned warp yarns changing from the lower, middle, lower, middle working position to the lower, middle, upper, middle, upper, middle working position for weaving. Likewise, in this embodiment, the interchangeability of the surface and inner patterned warp yarns can increase the color richness of the double-sided patterned jacquard fabric prepared in this embodiment. The interchangeability of the surface and inner patterned warp yarns needs to be determined according to the actual pattern design.

[0051] exist Figure 3 In the design, the outer layer weft yarns of the base fabric are numbered 1, 2 to 24, representing the first, second, and 24th weft yarns of the outer layer. Similarly, the inner layer weft yarns are also numbered 1, 2 to 24, representing the first, second, and 24th weft yarns of the inner layer. Figure 3 R1 and R2 in the diagram are both patterned warp yarns that can be changed from the outer layer to the inner layer. One yarn can be changed from the outer layer to the inner layer, and the other yarn can be changed from the inner layer to the outer layer.

[0052] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
