Description

Technical Field

[0001] This invention relates to a method for designing and manufacturing a double-sided jacquard fabric. Background Technology

[0002] Fabrics typically have distinct front and back sides, and can only be used on one side at a time, often requiring differentiation between them. Using only one side exposes it to sunlight and friction, shortening the product's lifespan; furthermore, it necessitates covering the back of the fabric, thus limiting its application range and increasing costs. Therefore, the design of double-sided fabrics and double-sided completely different fabrics is necessary.

[0003] Chinese patent CN 105908333 A discloses a "Method for Weaving Double-Sided Full-Color Jacquard Fabric," used to design and produce double-sided complex patterned jacquard fabrics. It possesses all the effects of double-sided full-color jacquard fabrics, meaning that either the front or back side of the fabric has an even number of yarns in one interlacing direction, while the other direction has a single group of yarns. The even numbers of yarns in the same direction used to represent the pattern effect on the front or back side do not overlap, exhibiting full-color characteristics and allowing for the display of multi-color halos and complex patterns on both sides of the fabric. However, its design steps are relatively complex, and the manufacturing process is also quite cumbersome. Summary of the Invention

[0004] The purpose of this invention is to provide a design and manufacturing method for double-sided jacquard fabrics, which aims to reduce the burden of fabric design and shorten the design cycle.

[0005] The technical solution of the present invention is as follows:

[0006] A method for designing and manufacturing a double-sided jacquard fabric includes the following steps:

[0007] S1. Select the loom configuration, determine the pattern repeat size and apparent warp and weft density;

[0008] S2. Design patterns for the front and back sides respectively, with the front and back patterns being the same size;

[0009] S3. Design the colors for the front and back;

[0010] S4. Design the paper specifications based on apparent warp density and apparent weft density, and complete the design drawings for the front and back sides respectively. Design the warp and weft arrangement, warp and weft combination, and organizational structure for the front and back sides based on apparent warp density and apparent weft density.

[0011] S5. Mirror the reverse design horizontally, then compare it with the front design. Figure 1 :1. The patterns are interlaced and overlapped, with the front pattern on the odd number of warp yarns and the back pattern on the even number of warp yarns;

[0012] S6. Select the filler weft and redesign the overall warp and weft arrangement based on the warp and weft arrangement on the front and back sides and the filler weft;

[0013] S7. Design organization: the organization of each area of ​​the front pattern is interwoven with the odd number of warp yarns that make up the outer warp, and the organization of each area of ​​the reverse pattern is horizontally mirrored. The warp organization points become weft organization points and interweave with the even number of warp yarns that make up the inner warp. The outer warp and inner warp are respectively connected to the filling weft to make the fabric a whole.

[0014] S8. Generate a pattern plate, weave it on a loom, and then heat-set it.

[0015] This invention designs fabrics with two completely different sides, allowing for different patterns, colors, textures, and materials on each side, resulting in entirely different styles. The layered design, with staggered overlay of patterns on the front and back sides and a weft-jointing design, ensures the fabric's strength and durability, effectively concealing the backing yarns and preventing the presence of yarns on one side from affecting the visual effect of the other. Furthermore, the staggered overlay of patterns on the front and back sides, compared to conventional straight overlay, means the total number of design colors is no longer an additive increase, but rather the sum of the design colors on both sides, significantly reducing the burden of weaving design and shortening the design cycle. This invention can be widely used in interior decorative fabric design, applied to home textile products such as curtains, roller blinds, screens, and tablecloths.

[0016] The present invention also has the following preferred designs:

[0017] The loom of the present invention uses 5280 needles.

[0018] The flower pattern of the present invention has a size of 9.8cm × 10cm.

[0019] The apparent warp and weft density of the present invention is specifically: apparent warp density 90 threads / cm, apparent weft density 30 threads / cm.

[0020] The loom described in this invention is an electronic jacquard loom.

[0021] The present invention has the following beneficial effects:

[0022] This invention designs fabrics with two completely different sides, allowing for different patterns, colors, textures, and materials on each side, resulting in entirely different styles. The layered design, with staggered overlay of patterns on the front and back sides and a weft-jointing design for the core, ensures the fabric's strength and durability, effectively concealing the backing yarns and preventing the presence of yarns on one side from affecting the visual effect of the other. Furthermore, the staggered overlay of patterns on the front and back sides, compared to conventional straight overlay, means the total number of design colors is no longer an additive increase, but rather the sum of the design colors on both sides, significantly reducing the burden of weave design and shortening the design cycle.

[0023] This invention can be widely used in the design of interior decorative fabrics and applied to home textile products such as curtains, roller blinds, screens, and tablecloths. Attached Figure Description

[0049] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments, so that those skilled in the art can better understand and implement the technical solution of the present invention.

[0050] A method for designing and manufacturing a double-sided jacquard fabric includes the following steps:

[0051] S1. Determine the product style, select the loom configuration, determine the repeat size and apparent warp and weft density. In this embodiment, the loom configuration uses 5280 needles, the repeat size is 9.8cm×10cm, the apparent warp density is 90 threads / cm, and the apparent weft density is 30 threads / cm.

[0052] S2. Design the patterns for the front and back sides respectively, such as Figure 1 and Figure 2 As shown, the front and back patterns are the same size;

[0053] S3. Design the colors for the front and back;

[0054] S4. Using the apparent warp and weft densities, design the paper specifications and complete the design drawings for the front and back sides respectively. The apparent warp and weft densities are used to design the warp and weft arrangement, combination, and weave structure for both sides. The front and back weave designs in this embodiment are as follows: Figure 3 and Figure 4 As shown;

[0055] S5. For example Figures 5 to 7 As shown, the reverse design is horizontally mirrored and then compared with the front design. Figure 1 :1. The warp yarns are interlaced and staggered, with the front pattern on the odd-numbered warp yarns and the back pattern on the even-numbered warp yarns. After overlapping, the warp repeat count doubles. The warp density is adjusted to 90 yarns / cm to make the front and back patterns consistent with the original. Figure 8 As shown;

[0056] S6. Select the filler weft. Redesign the overall warp and weft arrangement based on the warp and weft arrangement of the front and back sides and the filler weft. Since the filler weft only serves to connect the front and back fabrics into one, a finer and lower-cost yarn can be selected as the filler weft.

[0057] S7. Design organization: the organization of each area of ​​the front pattern is interwoven with the odd number of warp yarns that make up the outer warp, and the organization of each area of ​​the reverse pattern is horizontally mirrored. The warp organization points become weft organization points and interweave with the even number of warp yarns that make up the inner warp. The outer warp and inner warp are respectively connected to the filling weft to make the fabric a whole.

[0058] Specifically, see Figures 9 to 16 This embodiment uses the tissue structure design of color tissue No. 1, color tissue No. 2, color tissue No. 3, and color tissue No. 4 as examples to illustrate the design of the present invention in detail. In this embodiment, see... Figures 17 to 21 The warp yarns are represented by a and b, where 1a, 1b, 2a, and 2b are warp yarns, a is the outer warp and b is the inner warp. The weft yarns are represented by A, B, C, D, and E, where A and B are the outer weft, D and E are the inner weft, and C is the core weft.

[0059] The combination of outer and inner latitude can be determined according to design requirements, and is not limited to two types, but must be at least one. The outer warp can be either an odd number of root warp or an even number of root warp.

[0060] Section of region A Figure 18 The front side has a No. 1 color weave, and the back side has a No. 3 color weave. The front side has weft A on the front, and the back side has weft D on the back. The front warp and back warp are connected to weft C respectively.

[0061] Section of region B Figure 19The front side has a No. 1 color weave, and the back side has a No. 4 color weave. The front side has weft A on the outside, and the back side has weft E on the outside. The outer warp and inner warp are connected to weft C respectively.

[0062] Section of region C Figure 20 The front side has a No. 2 color weave, and the back side has a No. 4 color weave. The B weft is on the front side, and the E weft is on the back side. The front warp and the back warp are connected to the C weft respectively.

[0063] Cross section of region D Figure 21 The front side has a No. 2 color weave, and the back side has a No. 3 color weave. The B weave is on the front side, and the D weave is on the back side. The front warp and the back warp are connected to the C weave respectively.

[0064] S8. Generate a pattern plate, weave it on a loom, and then heat-set it. The loom selected is an electronic jacquard loom.

[0065] This embodiment, through layered design, staggered overlay of patterns on both sides, and the introduction of weft threads, ensures the fabric's strength and durability while effectively concealing the backing yarns, preventing the presence of yarns on one side from affecting the visual effect of the other. Jacquard fabrics woven on electronic jacquard machines can be completely different on both sides, with variations in patterns, colors, weaves, materials, and styles. Because the patterns on both sides are staggered during the design process, compared to the previous straight-line overlay, the total number of design colors does not increase exponentially, but rather is the sum of the number of design colors on both sides. This significantly reduces the burden of weaving design, greatly shortens the design cycle, and significantly improves design efficiency.

[0066] Figures 22 to 25 A double-sided, completely different fabric designed and manufactured according to the above-described principles of the present invention is demonstrated.

[0067] The above embodiments are merely preferred embodiments of the present invention, but should not be construed as limiting the invention. Any modifications and improvements made based on the concept of the present invention should fall within the protection scope of the present invention, and the specific protection scope is subject to the claims.
