Description

Technical Field

[0001] This application relates to the field of home textile pattern customization and dyeing, and in particular to a digital dyeing process for home textiles that generates AI-driven parametric 3D patterns. Background Technology

[0002] In the home textile industry, the rising aesthetic standards and personalized demands of consumers are driving the development of pattern design and printing and dyeing processes to a higher level. Traditional home textile pattern design relies heavily on designers' hand-drawn sketches and experience-based judgment, resulting in long creation cycles, low efficiency, and difficulty in accurately responding to the market's rapid demand for diversified and personalized products. Simultaneously, traditional printing and dyeing processes are typically fragmented with loosely connected procedures. From fabric pretreatment to pattern printing, different equipment and environments are often required, leading to extended production cycles, increased costs, and limitations in color reproduction, detail restoration, and three-dimensional effect presentation, making it difficult to achieve the realistic visuals and rich layers required for high-quality 3D patterns.

[0003] Currently, the market demand for home textile products, especially 3D patterned products with a three-dimensional feel, vibrant colors, and superior performance, is increasing. This requires the industry to achieve technological breakthroughs in both pattern generation and dyeing processes. Traditional hand-drawn patterns are inefficient, unable to meet the market's demand for rapid personalized customization, and difficult to achieve mass production. The inconsistency of traditional dyeing processes leads to low production efficiency and high costs, and its ability to render complex 3D patterns is insufficient, making it difficult to guarantee product quality and stability. Consequently, it cannot meet the market's demand for high-quality, personalized home textile products, and therefore needs improvement. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an AI-driven parameterized 3D pattern generation process for digital printing and dyeing of home textiles.

[0005] This application provides an AI-driven parametric 3D pattern generation digital printing and dyeing process for home textiles, which adopts the following technical solution: A digital printing and dyeing process for home textiles that uses AI to generate parametric 3D patterns includes the following steps: S1. Construction and Training: Construct a home textile pattern factor database, which includes historical patterns, 3D texture materials and corresponding process parameters; train an AI large model based on the database, which is a generative neural network capable of generating images according to parameterized instructions; S2, Generation and Application: Receives parameterized instructions from users on color, lighting parameters, depth and geometry, virtual light sources and materials, etc., and drives the AI ​​large model to generate initial digital flower drafts with 3D stereoscopic visual effects in batches. S3. Production Adaptation: Import the initial digital artwork into color separation software and image processing software, and make adjustments such as color separation, pixel optimization, color gamut mapping, dot compensation and process adaptation to generate production files that can directly drive digital printing equipment. S4. Fabric pretreatment: The selected fabric is subjected to spreading, singeing, alkali-oxygen cold stacking, oxygen bleaching, mercerizing, enzymatic hydrolysis and sizing treatment to obtain pretreated fabric. S5. Printing process: Digital printing is performed on the pre-treated fabric using production documents to obtain printed fabric. S6. Finishing: The printed fabric is steamed, washed, baked with resin, super-softened, calendered and pre-shrinked to obtain the finished fabric.

[0006] The precise 3D digital artwork generated by the AI-powered large-scale model lays the foundation for subsequent high-quality printing, ensuring the precision and color reproduction of the pattern. In the pretreatment process, the enzymatic hydrolysis helps remove surface fuzz from the fibers, while mercerizing improves the fibers' affinity for dyes and their own strength. Resin baking finishes can build stable covalent bonds and physical cross-linking networks between fibers, improving the fabric's anti-pilling, washability, and wrinkle resistance. The ultra-soft finish further enhances the bonding force between fibers and the surface smoothness, giving the fabric a soft feel while synergistically improving its durability and anti-pilling performance. The organic combination of these processes provides a precise pattern foundation for subsequent high-quality printing, and through optimized dyeing and finishing processes, the fabric's performance is improved together.

[0007] Preferably, the AI ​​large model in step S1 is a diffusion model.

[0008] By limiting the AI ​​model to a diffusion model, its unique progressive denoising generation mechanism can produce high-fidelity 3D stereoscopic floral initial images with rich details and natural transitions. This high-quality digital artwork provides more accurate and clear input for subsequent printing color separation and dot compensation, making ink deposition control and color transition in the printing process more optimized. At the physical level, this helps the printing paste or ink form a more uniform and firm bond on the fabric fibers, thereby improving the durability of the printed pattern and indirectly improving the overall wrinkle resistance and pilling resistance of the fabric due to the consistency of surface treatment.

[0009] Preferably, the resin baking and finishing in step S6 uses a resin finishing agent, which includes the following components by mass concentration: 60-80 g / L of low formaldehyde resin, 20-30 g / L of catalyst, 10 g / L of softener, and 1-2 g / L of neutralizing buffer.

[0010] Under the action of a catalyst, the low-formaldehyde resin undergoes a cross-linking reaction with the fabric fibers, forming a three-dimensional network structure inside and on the surface of the fibers. This structure not only significantly improves the wrinkle resistance and morphological stability of the fabric, but also helps the fabric maintain good tensile properties after finishing by enhancing the bonding force between fibers. The cross-linking network also effectively restricts the movement of fiber ends, thereby reducing the tendency of pilling due to friction. The appropriate amount of softener compounded in the system improves the lubricity of the fibers, making the fabric feel soft, and further enhances the anti-pilling performance by reducing the coefficient of friction between fibers. The neutralizing buffer maintains the chemical stability of the working solution, ensuring the uniformity and fullness of the cross-linking reaction, and promoting a more complete and dense protective layer. This helps to improve the durability of the finishing effect, thereby improving the light fastness of the fabric.

[0011] Preferably, the resin finishing agent further includes 10-20 g / L of a crosslinking agent; the crosslinking agent is prepared by the following steps: under a protective atmosphere, acrylic acid, hydroxyethyl acrylate and water are mixed, potassium persulfate is added, and prepolymerization is initiated by heating to obtain a prepolymer solution; a mixture of itaconic acid, amino-modified cage-type silsesquioxane and potassium persulfate is added to the prepolymer solution, the mixture is heated and stirred to react, cooled, tannic acid solution is added, the pH is adjusted to neutral after stirring, and the product is discharged to obtain the crosslinking agent.

[0012] By introducing a crosslinking agent into the base resin finishing agent, the overall performance of the finishing network is synergistically improved through the molecular design of the crosslinking agent. The itaconic acid unit in the crosslinking agent provides more carboxyl reaction sites, increasing the crosslinking density with fibers and resins. While significantly improving the wrinkle resistance of the fabric, its uniformity and toughness help the fabric maintain good tensile properties after finishing. Aminated cage-like silsesquioxanes are dispersed in the crosslinking network as rigid reinforcing points, improving the mechanical strength and abrasion resistance of the finishing film and helping to improve anti-pilling performance. At the same time, the introduced tannic acid structure can form various interactions with fibers through its polyphenolic hydroxyl groups and has certain ultraviolet absorption characteristics. Working together with the resin network, it improves the light fastness of the finished fabric. The crosslinking agent and the base resin system work together to form a denser and more stable finishing layer, synergistically improving the durability of the fabric from different mechanisms.

[0013] Preferably, the raw materials for preparing the crosslinking agent include the following components in parts by weight: 40-50 parts acrylic acid, 15-25 parts hydroxyethyl acrylate, 15-25 parts itaconic acid, 8-12 parts amino-modified cage-type silsesquioxane, 10-20 parts tannic acid, and 1-1.5 parts potassium persulfate.

[0014] The crosslinking agent synthesized according to the above mass proportions allows the functions of each component to work synergistically, acting together on the fiber surface to improve the uniformity and durability of the finishing effect.

[0015] Preferably, the ultra-softening finishing in step S6 uses an ultra-softening finishing agent, which comprises the following components at the following mass concentrations: hydrophilic microemulsion 15-20 g / L, hydrophilic softener 5-7 g / L, color-fixing agent 10-15 g / L, and neutralizing buffer 1-2 g / L.

[0016] The super-softening agent optimizes the fabric's hand feel and durability through the synergistic effect of its components. The hydrophilic microemulsion and hydrophilic softener form a lubricating layer on the fiber surface, not only giving the fabric a soft and smooth feel but also directly reducing the tendency to pill by effectively decreasing friction between fibers. The color-fixing agent in the formula enhances the binding force between dye molecules and fibers, improving color stability under light and thus improving the fabric's lightfastness. Simultaneously, the uniform and flexible film formed on the fiber surface by this finishing system provides auxiliary cohesion and protection for the fibers. This not only reduces the risk of structural damage to the fibers under stress and helps the fabric maintain good tensile properties but also enhances the overall durability of the fabric.

[0017] Preferably, the super-flexible finishing agent further includes 10-20 g / L of reinforcing agent, which is prepared by the following steps: Under a protective atmosphere, polycaprolactone diol and isophorone diisocyanate were mixed, and dibutyltin dilaurate was added. The mixture was heated and stirred to obtain a prepolymer. Dimethylolpropionic acid solution was added to the prepolymer. After the reaction, a functional monomer was added. After the reaction, the mixture was neutralized, emulsified, and distilled under reduced pressure to obtain a reinforcing agent.

[0018] The reinforcing agent is based on polyurethane, and the soft and hard segments in its molecular chain endow the film with elasticity and toughness. This elastic film layer forms on the fiber surface and between fibers, increasing fiber cohesion and thus helping to maintain good tensile properties of the fabric. The elastic recovery of the film layer also helps to improve the morphological stability of the fabric, thereby improving wrinkle resistance. At the same time, the uniform and continuous film layer covers and smooths the fiber surface, reducing the protrusion and entanglement of fiber ends during friction and improving anti-pilling performance. The stable chemical structure and complete film layer coverage of this reinforcing agent also provide more uniform protection for the internal dyes, reducing the influence of factors such as light exposure and synergistically improving the light fastness of the fabric.

[0019] Preferably, the raw materials for preparing the reinforcing agent include the following components in parts by weight: 90-100 parts of polycaprolactone diol, 28-32 parts of isophorone diisocyanate, 0.04-0.06 parts of dibutyltin dilaurate, 6-7 parts of dimethylolpropionic acid, and 16-22 parts of functional monomer.

[0020] The reinforcing agent synthesized according to the above ratio can form a stable chemical structure and has uniform film-forming properties, effectively enhancing the cohesion of fibers and thus improving the tensile properties of the fabric. The film layer smoothly covers the fiber surface, reducing friction and entanglement at the fiber ends, which helps to improve anti-pilling performance, reduces the influence of factors such as light, and synergistically improves the light fastness of the fabric.

[0021] Preferably, the functional monomers include fatty acid diethanolamide and isocyanate-based propyltriethoxysilane.

[0022] Fatty acid diethanolamide and isocyanate-propyltriethoxysilane are introduced as functional monomers in the reinforcing agent. The two synergistically construct a dual network with both dynamic physical crosslinking and stable chemical bonding. The amide groups in the fatty acid diethanolamide molecule can form multiple hydrogen bonds between polyurethane chains, forming reversible physical crosslinking points, dissipating stress, and thus improving the tensile properties and toughness of the fabric. Its excellent elastic recovery characteristics also directly contribute to improving the wrinkle resistance of the fabric. At the same time, after hydrolysis, the siloxane end groups of isocyanate-propyltriethoxysilane can form covalent bonds with the hydroxyl groups on the fiber surface, enhancing the interfacial bonding force between the finishing agent and the fiber. This strong anchoring effect improves the durability of anti-pilling performance. In addition, the inorganic network formed by this siloxane component in the finishing layer also enhances the overall structural stability, helps resist light aging, and thus synergistically improves the light fastness of the fabric.

[0023] Preferably, the mass ratio of the fatty acid diethanolamide to isocyanate-propyltriethoxysilane is 1:(1-1.5).

[0024] The above ratio balances the dual requirements of internal toughening of the reinforcing agent and strong interfacial bonding, effectively improving the tensile properties, light fastness and anti-pilling properties of the fabric.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The precise 3D digital artwork generated by the AI-powered large-scale model lays the foundation for subsequent high-quality printing, ensuring the precision and color reproduction of the pattern. In the pretreatment process, the enzymatic hydrolysis helps remove surface fuzz from the fibers, while mercerizing improves the fibers' affinity for dyes and their own strength. Resin baking finishes can build stable covalent bonds and physical cross-linking networks between fibers, improving the fabric's anti-pilling, washability, and wrinkle resistance. The ultra-soft finish further enhances the bonding force between fibers and the surface smoothness, giving the fabric a soft feel while synergistically improving its durability and anti-pilling performance. The organic combination of these processes provides a precise pattern foundation for subsequent high-quality printing, and through optimized dyeing and finishing processes, the fabric's performance is improved together.

[0026] By introducing a crosslinking agent into the base resin finishing agent, the overall performance of the finishing network is synergistically improved through the molecular design of the crosslinking agent. The itaconic acid unit in the crosslinking agent provides more carboxyl reaction sites, increasing the crosslinking density with fibers and resins. While significantly improving the wrinkle resistance of the fabric, its uniformity and toughness help the fabric maintain good tensile properties after finishing. Aminated cage-like silsesquioxanes are dispersed in the crosslinking network as rigid reinforcing points, improving the mechanical strength and abrasion resistance of the finishing film and helping to improve anti-pilling performance. At the same time, the introduced tannic acid structure can form various interactions with fibers through its polyphenolic hydroxyl groups and has certain ultraviolet absorption characteristics. Working together with the resin network, it improves the light fastness of the finished fabric. The crosslinking agent and the base resin system work together to form a denser and more stable finishing layer, synergistically improving the durability of the fabric from different mechanisms.

This elastic film layer forms on the fiber surface and between fibers, increasing fiber cohesion and thus helping to maintain good tensile properties of the fabric. At the same time, the uniform and continuous film layer covers and smooths the fiber surface, reducing fiber end protrusion and entanglement during friction and improving anti-pilling performance. The stable chemical structure and complete film layer coverage of this reinforcing agent also provide more uniform protection for the internal dyes, reducing the influence of factors such as light exposure and synergistically improving the light fastness of the fabric.
