Description

Technical Field

[0001] This utility model relates to the field of warp knitting technology, specifically to a soft Q double Jacquard fabric. Background Technology

[0002] Double jacquard fabric is a high-end material, produced using a double-sided weaving technique. It typically consists of two or more layers of interwoven yarns, allowing for intricate patterns and designs to be displayed on both sides. Compared to traditional single-sided jacquard fabric, double jacquard is more complex to weave, possessing higher technical sophistication and a unique visual effect.

[0003] Commercially available double Jacquard spacer materials typically use finer yarns or post-processing methods to ensure the overall softness of the material. However, if the yarn is too fine, the physical properties of the fabric cannot be guaranteed. Post-processing methods can also cause the material to feel slippery, affecting the subsequent shoe manufacturing process.

[0004] To address the problems mentioned in the background art, this utility model proposes a novel double Jacquard process. Double Jacquard jacquard fabrics produced using this process can guarantee a soft hand feel without post-finishing and can pass a series of physical performance tests. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a soft Q double Jacquard fabric, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a soft Q double Jacquard fabric, wherein the fabric is woven by an RDPJ4 / 2 double needle bed double Jacquard warp knitting machine, and the guide bars are GB1, JB2.1, JB2.2, JB3.1, JB3.2, and GB4 from front to back; Among them, GB1 is fully woven with the first yarn to form a base layer 1-0-1-0 / 0-1-0-1 / / . The JB2.1 and JB2.2 are fully woven with the second yarn to form a 1-0-1-0 / 1-2-1-2 / / structure to form the first jacquard layer; The JB3.1 and JB3.2 are fully woven with the third yarn in a 1-0-1-0 / 1-2-1-2 / / structure to form the second jacquard layer; The GB4 full-through fourth yarn weave 0-0-0-0 / 2-2-2-2 / / structure forms a spacer layer.

[0007] According to the above technical solution, the fabric further includes: Single-color jacquard area: The single-color jacquard area is woven with JB2.1 and JB2.2 using a 1-0-1-1 / 2-3-2-2 / / weave, and with JB3.1 and JB3.2 using a 1-1-1-0 / 2-2-2-3 / / weave. Another color jacquard area: The other color jacquard area is woven with JB2.1 and JB2.2 in a 1-1-1-0 / 2-2-2-3 / / pattern, and JB3.1 and JB3.2 in a 1-0-1-1 / 2-3-2-2 / / pattern; One- or two-color gradient area: The one- or two-color gradient area is formed by combining a one-color jacquard area and a two-color jacquard area; Large mesh area: The large mesh area is woven with JB2.1 and JB2.2 in the pattern 1-0-1-1 / 1-2-2-2 / / and 2-1-1-1 / 2-3-2-2 / / , and with JB3.1 and JB3.2 in the pattern 1-1-1-0 / 2-2-1-2 / / and 1-1-2-1 / 2-2-2-3 / / .

[0008] According to the above technical solution, the first yarn is 50D / 72F polyester low elastic yarn, the second and third yarns are 75D / 36F polyester fully drawn yarn, and the fourth yarn is 100D / 48F polyester monofilament.

[0009] According to the above technical solution, the fabric surface forms a three-dimensional pattern structure with a pattern height difference of 0.5-1.2mm, a porosity of 35-45% in the mesh area, a yarn padding angle of the GB1 comb of 45-60°, and an offset of 1.5-2 stitch lengths for the JB series Jacquard comb.

[0010] This invention provides a soft, Q-resistant double jacquard fabric. It has the following beneficial effects: (1) This utility model can ensure its soft hand feel without the need for post-processing. At the same time, it can use yarn of any thickness and does not require the addition of softener in the post-processing, which reduces the difficulty of production and improves the quality of the product.

[0011] (2) This utility model, through the four-area organizational structure design combined with specific yarn configuration, allows the yarn to slip slightly in the fabric to improve softness, while maintaining the overall structural stability. This allows the fabric to meet the softness requirements when the toe is bent, and to maintain the stability of the shoe shape through structural support. It can achieve dual optimization of feel and performance without finishing softener, breaking through the bottleneck of traditional processes where both are difficult to balance.

[0012] (3) This utility model forms a nanoscale rough structure on the yarn surface by plasma modification of polyester low elastic yarn and spandex covered yarn, which improves the dye adsorption rate and solves the problem of uneven dyeing of dark fabrics in traditional processes. It also reduces the slippage phenomenon during weaving by increasing the yarn friction coefficient, which significantly improves the stability of the production process and the uniformity of fabric quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 One embodiment of this utility model is: a soft Q double Jacquard fabric, the fabric is woven by an RDPJ4 / 2 double needle bed double Jacquard warp knitting machine, and the guide bars are GB1, JB2.1, JB2.2, JB3.1, JB3.2 and GB4 from front to back; Among them, GB1 full-penetration first yarn weaving 1-0-1-0 / 0-1-0-1 / / weave forms the base layer; JB2.1 and JB2.2 are fully woven with the second yarn in a 1-0-1-0 / 1-2-1-2 / / pattern to form the first jacquard layer; JB3.1 and JB3.2 are fully woven with the third yarn in a 1-0-1-0 / 1-2-1-2 / / pattern to form the second jacquard layer; GB4 full-width weave of the fourth yarn 0-0-0-0 / 2-2-2-2 / / weave to form a spacer layer.

[0016] The fabric also includes: Monochromatic Jacquard Area: The monochromatic jacquard area is woven with JB2.1 and JB2.2 using a 1-0-1-1 / 2-3-2-2 / / weave, and with JB3.1 and JB3.2 using a 1-1-1-0 / 2-2-2-3 / / weave. Another color jacquard area: The other color jacquard area is woven with JB2.1 and JB2.2 in a 1-1-1-0 / 2-2-2-3 / / pattern, and JB3.1 and JB3.2 in a 1-0-1-1 / 2-3-2-2 / / pattern. One- or two-color gradient area: A one- or two-color gradient area is formed by combining a jacquard area of ​​one color with a jacquard area of ​​another color; Large mesh area: The large mesh area is woven with JB2.1 and JB2.2 in the pattern 1-0-1-1 / 1-2-2-2 / / and 2-1-1-1 / 2-3-2-2 / / , and with JB3.1 and JB3.2 in the pattern 1-1-1-0 / 2-2-1-2 / / and 1-1-2-1 / 2-2-2-3 / / .

[0017] The first yarn is 50D / 72F polyester low-elasticity yarn, the second and third yarns are 75D / 36F polyester fully drawn yarn, and the fourth yarn is 100D / 48F polyester monofilament.

[0018] The fabric surface forms a three-dimensional pattern structure with a pattern height difference of 0.5-1.2mm, a porosity of 35-45% in the mesh area, a padding angle of 45-60° for the GB1 comb, and an offset of 1.5-2 stitch lengths for the JB series Jacquard comb.

[0019] A method for producing a soft, Q-textured double jacquard fabric includes the following steps: Step 1, Yarn Pretreatment: The first yarn is subjected to plasma treatment during the warping stage, and the second and third yarns are treated with emulsion impregnation. Step 2, Weaving Parameter Setting: Using the RDPJ4 / 2 double needle bed warp knitting machine, set the front needle bed temperature to 24-26℃ and the rear needle bed temperature to 22-24℃; Step 3, Weaving on the machine: Thread the yarn in the guide bar sequence of GB1, JB2.1, JB2.2, JB3.1, JB3.2, GB4, set the weaving speed to 1600-2000 r / min, machine size E24-E28, and tension to 100-130 cN; Step 4, Dynamic Tension Closed-Loop Control: Strain gauges are used to monitor the tension of the yarns in each comb bar in real time during the weaving process; Step 5, Online Forming Control of Three-Dimensional Structure: Install a laser displacement sensor 15cm away from the weave opening to detect the height difference of the pattern in real time; Step 6, In-situ heat setting: An infrared heating zone is set in front of the tension roller to pre-set the fabric while it is not completely cooled. Step 7, dyeing and primary setting: Disperse dyes are applied under high temperature and high pressure using a stepped heating method, followed by primary setting.

[0020] In step one, the plasma is controlled at 80-120W, the treatment time is 15-30 seconds, the treatment gas is a mixture of argon and oxygen (volume ratio 3:1), and the emulsion wetting temperature is 60-65℃. Through plasma etching, a nanoscale rough structure is formed on the yarn surface (roughness Ra value increases from 0.2μm to 0.5-0.7μm), which increases the dye adsorption rate by 15%-20% during subsequent dyeing. Simultaneously, it enhances the friction coefficient between the yarn and the Jacquard weave (friction coefficient increases from 0.18 to 0.25-0.3), reducing yarn slippage during weaving and improving pattern clarity.

[0021] In step four, the sampling frequency is 500Hz. Simultaneously, when tension fluctuations exceed the set value ±10%, the warp feed is dynamically adjusted via a servo motor. This solves the problem of sudden tension changes in the gradient zone caused by weave switching and further reduces the yarn breakage rate.

[0022] In step five, when the detected value is <0.5mm, the JB guide bar offset is automatically increased; when the detected value is >1.2mm, the GB4 guide bar feed is reduced. This ensures that the pattern's three-dimensionality remains stable within the range of 0.5-1.2mm, while also preventing structural collapse due to differences in yarn shrinkage.

[0023] In step six, the heating temperature is 80-100℃, and the heating time is 2-3 seconds. This eliminates internal stress, reduces the shrinkage rate of subsequent pre-forming processes, and at the same time, the infrared heating selectively acts on high-density areas to avoid deformation of the mesh area.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
