[0033] In the high-strength antibacterial layer, nano-silver antibacterial fibers are added, in the fluffy shape-retaining layer, aerogel fibers are introduced, and in the corrosion-resistant layer, aramid fibers are added.

[0034] Through the above technical solution, the nano-silver has broad-spectrum antibacterial properties and can inhibit and kill a variety of bacteria, fungi and viruses, and the antibacterial effect is long-lasting, and the good dispersibility of the nano-silver antibacterial fibers does not affect the strength and stability of the overall fiber structure, the aerogel fibers have extremely low density, high porosity and excellent thermal insulation performance, the aramid fibers have high strength, high modulus, high temperature resistance, chemical corrosion resistance and other excellent properties, and the addition of aramid fibers in the corrosion-resistant layer can significantly improve the corrosion resistance and mechanical properties of the non-woven fabric in harsh environments.

[0035] The fluffy and permanent layer is divided into two layers, the inner layer uses high proportion of spiral crimped polyester fiber (90%-95%), and the outer layer uses low melting point polyester fiber and a small amount of aerogel fiber (low melting point polyester fiber accounts for 80%-85%, and aerogel fiber accounts for 15%-20%).

[0036] Through the above technical scheme, the high proportion of spiral crimped polyester fiber in the inner layer ensures the fluffiness and resilience of the non-woven fabric inside, providing comfort for wearing or using, and the low melting point polyester fiber in the outer layer is tightly bonded with other layers during hot pressing, while the presence of aerogel fiber makes the outer layer have certain heat insulation performance and can protect the inner layer fiber structure from being affected by the external environment.

[0037] In the non-woven fabric selection step, a smart sensing non-woven fabric is introduced, which has a nano material sensitive to temperature, humidity, light and other environmental factors embedded inside. The pretreatment step uses low temperature plasma treatment technology. The type selection step develops light curing color changing ink. The color matching step introduces a digital intelligent color matching system. The equipment inspection uses a smart detection system to monitor the operating status of the key components of the printing machine in real time. The debugging parameters use self-adaptive parameter adjustment technology.

[0038] Through the above technical scheme, when the environmental temperature rises, the color in the printing pattern will gradually become lighter or change in hue. When the light conditions change, the pattern may also have dynamic effects. In a low pressure environment, gas plasma is excited. These plasma particles carrying high energy particles perform micro-etching on the surface of the non-woven fabric, greatly increasing the surface roughness and active sites, and the ink penetrates more uniformly. The light curing color changing ink contains special photochromic compounds that can quickly change color under different wavelengths of light, allowing multiple pattern effects to be presented according to light conditions, greatly enriching the creative space of printing design. Through high-precision spectral analysis, the color card is scanned to obtain accurate color data, and then combined with the characteristics of the ink, the parameters of the printing equipment, and the absorption characteristics of the non-woven fabric, the best ink matching ratio is automatically calculated using an algorithm. Sensors are installed at key points of the printing machine to collect real-time data such as temperature, vibration, and current. With the help of big data analysis and artificial intelligence algorithms, the running state of the equipment is monitored and analyzed in real time to predict potential failure risks in advance. Before the printing equipment is running, the non-woven fabric sample is scanned and analyzed in all directions to obtain detailed information such as material, thickness, and texture. Then, combined with the complexity and precision requirements of the ink type and printing pattern, the printing machine parameters are automatically optimized and adjusted.

[0040] Through the above technical solutions, the advanced image recognition algorithm is used to analyze the complex pattern in depth, automatically and accurately recognize different color and shape elements, and accurately layer and separate them. The surface of the flexible intelligent screen material is coated with a special intelligent coating. After completing a printing, the coating can automatically restore to the initial state through a specific temperature and electric field treatment, removing the residual ink, realizing the repeated use of the screen, greatly reducing the production cost. At the same time, the screen mesh can be flexibly adjusted through the external electric field to meet the needs of different precision printing patterns. Through the customized 3D printing nozzle, the coating thickness and shape of the photosensitive glue are accurately controlled according to the pattern design, forming a complex three-dimensional photosensitive glue structure on the screen. This unique structure can make the ink more evenly distributed during the squeegee printing process, significantly improving the edge definition and detail performance of the printed pattern, especially for high-precision and complex pattern printing. A high-resolution laser beam is used to directly draw patterns on the screen coated with photosensitive glue, eliminating the need for pattern film making and avoiding precision loss and environmental pollution in the film making process. The laser exposure time and energy can be accurately controlled, and the exposure precision can reach specific precision values, greatly improving the screen making quality. The self-adaptive image format conversion algorithm can automatically optimize the image resolution, color depth and file size according to the characteristics of the printer nozzle, ink injection volume and non-woven fabric absorption performance when converting the design pattern file to a format suitable for digital printing machines, effectively reducing the printing data volume and improving the printing speed while ensuring the printing quality. The color calibration system collects a large amount of actual printing data and corresponding design pattern color data of the printer, and establishes a precise color mapping model through a deep learning algorithm. Before printing, the system automatically adjusts the color output parameters of the printer according to the design pattern color using the model, realizing more accurate color restoration, and the color accuracy is improved compared with traditional methods.
