Description

Technical Field

[0001] This invention relates to the field of chemical fiber technology, and in particular to a preparation process and fabric of a four-color warp jacquard fabric based on printing effect. Background Technology

[0002] With social progress and improved living standards, people are paying increasing attention to enhancing their quality of life. "Beautiful, green, and environmentally friendly" textiles are gaining more and more importance. In the clothing fabric market, vibrant, colorful, and eco-friendly patterned fabrics have become highly sought-after products, demonstrating strong growth momentum.

[0003] Patterned fabrics can be divided into jacquard fabrics and printed fabrics.

[0004] Jacquard fabrics are woven by combining different colored yarns and weaves to directly create patterns on the fabric. The resulting designs are three-dimensional, with a textured feel, and can be woven into various patterns such as flowers, birds, fish, insects, and animals. They are beloved by fashion designers and the general public. Jacquard fabrics have a wide range of uses, not only for making casual dresses, sportswear, suits, and bedding, but also for traditional Chinese clothing such as cheongsams and Hanfu.

[0005] Printed fabrics are created by printing patterns directly onto the raw fabric using pigments or dyes. Printed fabrics offer a wide variety of colors and patterns, can be printed on both thick and thin fabrics, have a wide range of applications, can be mass-produced, and are cost-effective, making them a popular textile and apparel fabric choice.

[0006] Jacquard and printed fabrics each have their own unique characteristics and advantages. Jacquard fabrics are formed through variations in the warp and weft threads of different colors, while printed fabrics are created by directly printing patterns onto the raw fabric using dyes. Compared to printed fabrics: Jacquard fabrics have several advantages.

[0007] On the one hand, because its patterns and colors are formed directly through weaving, it avoids the use of dyes and auxiliaries in printing processes, making it more environmentally friendly. Moreover, the fabric has higher color fastness and the patterns are more three-dimensional. At the same time, the range of yarn raw materials that can be selected is wider than that of printed fabrics. On the other hand, because the patterns and colors of jacquard fabrics are closely related to the warp and weft colors used, the more warp and weft colors are used, the richer the fabric colors are, but the corresponding fabric will also be thicker and the cost will be relatively higher. On the other hand, the richness of colors of printed fabrics is not affected by the thickness of the fabric, and rich patterns can be printed on thin fabrics.

[0008] Jacquard fabrics are widely used due to their environmental friendliness, high colorfastness, more three-dimensional patterns, and wide range of yarn raw materials. However, the inherent drawbacks of jacquard fabrics also affect the user experience. Therefore, it is necessary to improve jacquard fabrics to enrich their application scenarios and enhance the user experience. Summary of the Invention

This invention provides a four-color warp jacquard fabric based on printing effects, as well as its preparation process.

[0010] This invention relates to a four-color warp jacquard fabric based on a printed effect. Utilizing the CMYK principle, and through research into jacquard technology, it achieves pattern colors by employing yarn color mixing and weave coordination.

[0049] The representative embodiments shown in the accompanying drawings will now be further refined. It should be understood that the following description is not intended to limit the embodiments to a single preferred embodiment. Rather, it is intended to cover alternatives, modifications, and equivalents that may be included within the substance and scope of the embodiments defined by the appended claims.

[0050] In the following detailed description, reference is made to the accompanying drawings, which form part of this specification, and specific embodiments according to the described embodiments are illustrated by way of example. While these embodiments have been described in sufficient detail to enable those skilled in the art to implement them, it should be understood that these examples are not limiting, allowing for the use of other examples and appropriate modifications without departing from the spirit and scope of the described embodiments.

[0051] The preparation process of the four-color warp jacquard fabric based on the printing effect in this solution includes the following steps:

[0052] Raw material selection: In accordance with the four-color printing principle, four colors of red, blue, yellow and black with a thickness of 30D / 24F to 50D / 36F are selected as warp yarns; white or black yarn with a thickness of 50D / 36F to 75D / 72F is selected as weft yarns; the warp and weft yarns are made of polyester yarn.

[0053] Warp twisting: Twist the selected warp yarns individually at a twist rate of 800 r / m;

[0054] Yarn configuration: Configure the required color yarns using four-color warp yarns according to the four-color printing pattern;

[0055] Fabric weaving: Select four colors of yarn, namely red, blue, yellow and black, as warp yarns and white or black yarns as weft yarns. Use a double warp structure and a jacquard loom to weave to obtain jacquard fabric.

[0056] Jacquard fabric finishing: The finishing process is carried out on the jacquard fabric obtained after weaving.

[0057] The finished fabric is rolled up and packaged.

[0058] In fabric weaving, specifically:

[0059] (1) Background weave: The background weave is a weft satin weave; such as Figures 1-4As shown, the base weave is made of 8-end 3-fly weft satin weave and 16-end 3-fly weft satin weave; the weave pattern is made of 8-end 3-fly weft satin weave or a composite weave of 8-end 3-fly weft satin backed with 16-end 3-fly weft satin.

[0060] (2) Pattern structure: The pattern structure adopts a warp satin weave; the pattern color is achieved by combining four different colors of warp yarn floats and using the method of warp yarn color mixing.

[0061] The floral pattern uses a warp satin weave to enrich the colors and layers of the pattern and make it more lustrous.

[0062] The specific floral pattern and color are achieved through a combination of four different colored warp yarn floats, using a warp yarn color mixing technique. For example, the orange floral pattern effect is created by interweaving red and yellow warp yarns with the weft yarns. Figure 5 The image shows a simulation of an orange effect created by the interweaving of red and yellow warp yarns with black weft yarns. In the image, the red warp yarns and black weft yarns are arranged in a 16-end, 3-fly reinforced warp-faced satin weave, while the yellow warp yarns and black weft yarns are arranged in an 8-end, 3-fly warp-faced satin weave. This results in a mixed color configuration of red and yellow warp yarns with varying floats on the fabric surface, creating the orange effect. Figure 6 A weave diagram showing the surface layer formed by the interlacing of red and yellow warp yarns and black weft yarns; Figure 7 This is a picture of a fabric made of red and yellow warp yarns interwoven with black weft yarns.

[0063] Yarn color matching and weave design:

[0064] The design is based on the CMYK principle: red patterns are created by interweaving red warp and weft yarns using an 8-end 5-fly satin weave to represent red; green patterns are created by interweaving yellow warp yarns and blue weft yarns to form green, and vice versa; orange patterns are created by interweaving red and yellow warp and weft yarns respectively; or any color other than white can be created by using three colors of warp yarns.

[0065] The floral pattern of the jacquard fabric uses satin weave and reinforced satin weave, while the base pattern uses a weft-faced weave.

[0066] The finishing process specifically includes washing and setting. The washing temperature is 80-100℃ and the washing speed is 30-40m / min. The setting temperature is 160-170℃ and the setting speed is 28-40m / min.

[0067] Example 1: The floral design "Little Bird Leaning Against a Person" was selected, specifically as follows: Figure 8-13 As shown;

[0068] The bird pattern in design 1 is woven from four colors of warp yarns and white weft yarns. The red and black warp yarns are each arranged in a 16-end, 3-row warp satin weave with varying numbers of dots, forming the outer layer of the fabric. The yellow and blue warp yarns are arranged in a 16-end, 3-row weft satin weave, forming the inner layer, thus creating a complete double-warp weave. The floral pattern on the surface of the bird uses a 16-end, 3-row warp satin weave with a shimmering effect, creating a distinct and gradual style on the fabric surface, resulting in a lifelike effect. Figure 8 For the floral design of "Little Bird Leaning Against a Woman", Figure 9 This is a surface tissue diagram. Figure 10 This is a diagram of the inner tissue layer. Figure 11 This is a diagram of a double-warp weave structure, where four-color warp yarns are interwoven with white weft yarns. Figure 12 This is a partial fabric structure diagram. Figure 13 This is a partial image of the fabric.

[0069] Example 2: Selected Flower Design 2 "Starry Sky", such as Figure 14-19 As shown;

[0070] The second design, "Starry Sky," features a richer color palette, employing a wider range of warp colors for the fabric's surface. For example, blue and red warp yarns interweave with black weft yarns to create purple; blue and yellow warp yarns interweave with black weft yarns to create green; and black and blue warp yarns interweave with black weft yarns to create dark blue, and so on. In the purple weave configuration, red warp yarns interweave with black weft yarns using a 16-end 3-fly warp-faced satin weave, while blue warp yarns interweave with black weft yarns using an 8-end 3-fly warp-faced satin weave, forming the fabric's surface layer. Similarly, yellow warp yarns interweave with black weft yarns using a 16-end 3-fly weft-faced satin weave, while black warp yarns interweave with black weft yarns using an 8-end 3-fly weft-faced satin weave, forming the inner layer and creating a complete double-warp weave. This pattern continues, with variations in warp yarn arrangement and weave, resulting in different textures and colors on the fabric surface. Figure 14 For the floral design of "Starry Sky", Figure 15 This is a surface weave diagram showing the interlacing of red and blue warp yarns with black weft yarns. Figure 16 This is a diagram of the inner layer weave, consisting of yellow and black warp yarns interwoven with black weft yarns. Figure 17 This is a diagram of a double-warp weave structure, where four-color warp yarns are interwoven with black weft yarns. Figure 18 This is a partial fabric structure diagram. Figure 19 This is a partial image of the fabric.

[0071] The fabrics in Examples 1 and 2 are mainly used to make fashionable clothing such as cheongsams, skirts, and shirts, primarily for spring and summer. The fabrics are required to be lightweight, breathable, soft to the touch, and yet sturdy, with a weight of approximately 100-150 g / m². To improve comfort and reduce costs, polyester is the primary material used. Specific specifications are designed as follows.

[0072] Machine width (cm): 168;

[0073] weight (g / m 2 100-150;

[0074] Yarn fineness (d): warp fineness 50, weft fineness 75;

[0075] Weaving density (roots / 10cm): warp density 1280, weft density 600.

[0076] Based on the above fabric specifications, the finished width is approximately 155cm, the warp density is approximately 1330 threads / 10cm, and the weft density is approximately 650 threads / 10cm.

[0077] To ensure good dimensional stability and enhance the fabric's crispness, smoothness, and drape, polyester twisted yarns are selected for both warp and weft, while a satin weave is chosen as the primary fabric structure to improve its luster and hand feel.

[0078] Machinery and Equipment: Based on the current state of textile machinery and equipment and the specifications of fabric weaving, the following machinery and equipment are selected: an electronic jacquard loom with a 5376-needle head; manufactured by Kuangda, a domestic manufacturer; the loom will be either air-jet or arrow-type. The head, manufacturing equipment, and loom will work together to complete the equipment selection and configuration.

[0079] Yarn: Based on market yarn specifications, twisted colored spun yarn is used. Colored spun yarn has masterbatch added during the spinning process, giving it a color after spinning. This eliminates the need for further dyeing at a dyeing plant. Compared to dyed yarn, colored spun yarn offers better colorfastness, environmental performance, and lower cost. The warp yarn is 50D / 36F twisted colored spun yarn, and the weft yarn is 75D / 72F colored spun yarn. The twisting process makes the fabric feel stiffer and has better drape.

[0080] Warping: The warp yarns are black, red, yellow, and blue, arranged in a 1:1:1:1 ratio. Common slitting warping machines typically use small warp rollers capable of holding 800 or 1200 bobbins. This fabric has a warp density of 128 / cm, a single-width weave width of 168cm, and is woven in a 2-way configuration, resulting in a total width of 336cm. Therefore, the total number of warp ends is 43008. To increase warping efficiency, a small warp roller capable of holding 800 bobbins is selected. Analysis and calculation show that holding 768 bobbins is more reasonable for the following reasons: First, 768 bobbins are divisible by the four colors, with each color divided into 192 small bobbins; second, the total number of warp ends, 43008, is divisible by 768, meaning 56 warp ends are drawn, a whole number that improves warping efficiency. Considering these factors, 768 bobbins are chosen, with 56 warp ends drawn.

[0081] On the loom: After the operator prepares the warp beam according to the warp yarn arrangement requirements, it is transported to the weaving workshop. The warp splicing operator splices the warp yarns on the new warp beam with the warp yarns on the machine according to the warp yarn arrangement. After the new beam is spliced ​​with the warp yarns on the loom, the machine stopper winds the spliced ​​warp yarns onto the warp beam. During the warping and splicing process, the four colors of warp yarns are prone to not being arranged in the required order. Therefore, the machine stopper must perform start-up and correction operations according to the warp yarn arrangement order before starting the machine to ensure that the warp yarns are arranged as required and to avoid misaligned or broken warp yarns, which would affect the fabric surface effect and quality.

[0082] Temperature and humidity control: To improve the environment of the weaving workshop, meet the requirements for normal loom operation and product quality, and enhance the management level of operators, the workshop must maintain a stable and suitable temperature and humidity. Due to the different requirements of various equipment types, the temperature and humidity requirements differ. Since the selected raw material is mainly polyester, the temperature and humidity requirements of the workshop are relatively less stringent than those for silk or cotton. Maintaining a certain temperature and humidity is sufficient, generally between 20-28 degrees Celsius and 50%-75% relative humidity.

[0083] Weaving Tension Control: In the weaving process of four-color warp products, appropriate loom tension is required to ensure fabric style and clear sheathing. Excessive tension causes warp yarn elongation, leading to warp breakage and an overly tight fabric. Insufficient tension easily causes warp yarn slack, resulting in unclear sheathing, warp yarn breakage, and the slack warp yarns catching on the weft yarns, causing weft stoppage and affecting product quality and weaving efficiency. Therefore, controlling weaving tension is crucial. Depending on the weaving production situation, the weaving tension should ideally be controlled at around 2000-2500N.

[0084] The machine speed is generally controlled at 450 rpm. Because a jacquard loom and a jacquard loom are used, the fabric has a high warp density. The jacquard loom requires high steel quality, load-bearing capacity, and precision, so the machine speed should not be too fast and should be controlled at 450 rpm.

[0085] After weaving is completed, finishing processes are carried out.

[0086] The developed four-color warp fabric belongs to the yarn-dyed jacquard fabric category. The fabric washing process is as follows: unwinding inspection—washing—setting—rolling and packaging. Its washing and setting process and parameters are as follows.

[0087] Unwinding inspection: After the fabric is woven in the weaving factory, it will undergo a preliminary inspection and be rolled and packaged from the loom to the grey fabric warehouse. After arriving at the washing and finishing plant, it will be unwound and inspected again to determine the length of the fabric to be stored.

[0088] Washing: Depending on the fabric requirements, washing may involve either plain water or the addition of auxiliaries such as softeners. The developed four-color warp fabric is a 100% polyester yarn-dyed fabric, woven on imported air-jet looms. Compared to water-jet looms, these looms produce a cleaner fabric surface, thus requiring no auxiliaries during washing; plain water is sufficient. Therefore, the standard washing process for polyester fabrics is used. The washing temperature is controlled between 80 and 100 degrees Celsius, and the washing machine speed is between 30 and 40 m / min.

[0089] Setting: The quality of the setting process directly affects the neatness, width, and stability of the fabric's width. Post-setting finishing is a crucial step in enhancing the fabric's value. The quality of fabric setting depends on the setting temperature and setting speed. The four-color warp fabric we developed is made entirely of polyester. Polyester's melting point is around 260 degrees Celsius. If the setting temperature is too high, the fabric will feel too stiff, have greater thermal shrinkage, and affect its dimensional stability. If the setting temperature is too low, due to the molecular arrangement of polyester raw materials, uneven heating will occur, also affecting the fabric's dimensional stability. At the same time, setting temperatures that are too high or too low will also affect the fabric's color. The same principle applies to setting speed. If the speed is too high, the washed fabric will dry unevenly, and color variations will occur. If the speed is too low, the drying time during setting will be too long, resulting in a stiff fabric feel and color distortion. Therefore, setting is a very important step in the entire finishing process. Through repeated practice, the setting temperature of the four-color warp fabric was controlled between 160-170 degrees Celsius, and the machine speed was controlled between 28-40m / min.

[0090] Rolling and Packaging: After shaping, the product is rolled and packaged. During rolling, it's crucial to control the rolling speed to avoid wrinkles. Hygiene and cleanliness must also be maintained during packaging to prevent secondary contamination.

[0091] The fabric products prepared above were tested by the Textile and Apparel Product Quality Supervision and Inspection Center (Zhejiang), and all technical indicators fully met the expected results.

[0092] Please see the following test report results for details:

[0093] 1. Fabric areal density: <150g / m2

[0094] 2. Colorfastness: ≥ Grade 4

[0095] 3. Formaldehyde: less than the detection limit (20 mg / kg)

[0096] 4. Decomposable aromatic amines: less than the detection limit (5 mg / kg)

[0097] 5. Heavy metals: less than the detection limit or meeting the standards for infant and toddler textiles.

[0098] 6. pH value: ≤7.0.

[0099] This project utilizes four colors of warp yarns—red, blue, yellow, and black—along with black or white weft yarns, and employs a double-warp weave structure to create different float lengths for these four different colored warp yarns. By mixing and configuring the warp yarns, the project achieves rich colors in the pattern design, developing a new type of lightweight jacquard fabric that is rich in color, has a strong three-dimensional effect, low surface density, good environmental performance, and printable effect.

[0100] Four-color warp jacquard fabric with a printed effect has changed the traditional heavy and expensive nature of multi-colored jacquard fabrics, achieving product innovation with rich colors and lightweight texture. Moreover, compared with printed fabrics, it not only overcomes the limitations of material use but also improves the color fastness and environmental performance of the product. This is of positive significance in meeting the market's demand for healthy, environmentally friendly, and cost-effective multi-colored fabrics, and its application prospects are very broad.
