Analysis of environmentally friendly dyeing technology and development of Jacquard elastic cloth composite TPU fabric

Overview of Jacquard Stretch Cloth Composite TPU Fabric

Jacquard stretch fabric composite TPU (thermoplastic polyurethane) fabric is a new textile material that combines functionality and aesthetics. This fabric consists of two main components: the outer layer is jacquard fabric and the inner layer is TPU film, which is closely bonded by hot pressing or adhesive processes. Its core feature is that it has soft and elasticity, waterproof and breathable properties, and complex pattern design capabilities, making it widely used in outdoor sportswear, protective clothing, medical supplies and home decoration fields.

Jagua fabrics are used as outer fabrics, and warp and weft yarns are staggered to form specific patterns, giving the product a unique visual effect and touch experience; while TPU films are due to their outstanding physical and chemical characteristics – such as high-strength stretch recovery Properties, oil stain resistance and good low temperature flexibility – significantly enhance the functional properties of the overall material. In addition, because the TPU itself is recyclable, this composite fabric also shows great potential in environmental protection.

As the global focus on sustainable development is increasing, environmental pollution caused by traditional dyeing technologies is receiving more and more attention. Therefore, exploring environmentally friendly dyeing technology suitable for jacquard elastic cloth composite TPU fabrics has become one of the hot spots in the industry. These technologies need not only meet high-performance needs, but also minimize chemical use and wastewater emissions to achieve true green production goals. Next, we will explore in-depth several representative environmentally friendly dyeing methods and their specific applications.

Overview of environmentally friendly dyeing technology

In the textile industry, traditional dyeing methods often involve large amounts of chemical reagents and water resources consumption, resulting in serious environmental problems. In order to meet this challenge, a variety of environmentally friendly dyeing technologies have emerged in recent years, including advanced methods such as digital inkjet printing, supercritical CO2 dyeing, and biological enzyme treatment. These technologies not only significantly reduce the use of water and chemicals, but also improve dyeing efficiency and color durability, providing a more sustainable option for the production of jacquard stretch fabric composite TPU fabrics.

Digital inkjet printing technology

Digital inkjet printing is a contactless dyeing technology that sprays dye directly onto the surface of the fabric through high-precision nozzles, achieving the goal of distributing dyes on demand. This approach greatly reduces dye waste and allows precise control of color concentration and location, making it ideal for design needs of complex patterns. According to a study by Smithers Pira, digital inkjet printing can reduce water consumption by about 70% and energy consumption by 50% compared to traditional cylinder printing [1]. In addition, since the plate making process is not required, digital inkjet printing is particularly suitable for small batch customization production, which is an important trend in the Jacquard stretch fabric composite TPU fabric market.

Supercritical CO2 dyeing technology

Supercritical CO2 dyeing technology uses carbon dioxide at its critical point toThe state on the top serves as a solvent to transfer dye molecules into the fibers. This method completely avoids the use of water. At the same time, since CO2 can evaporate quickly at room temperature, no residue will be left. This technique is particularly suitable for synthetic fibers that are difficult to dye by conventional methods, such as TPU films. According to the Textile Research Journal, the dye absorption rate during supercritical CO2 dyeing can reach 98%, which is much higher than that of traditional water bath dyeing [2]. However, this technology still faces challenges such as high equipment costs and high technical thresholds, but with the advancement of technology, its application prospects are widely optimistic.

Bioenzyme treatment technology

Bioenzyme treatment technology uses enzymes produced by specific microorganisms to decompose or change the chemical structure to achieve the purpose of cleaning or pretreatment. For example, using pectinase before dyeing to remove impurities from natural fibers, or using protease to improve the surface properties of synthetic fibers can effectively improve the subsequent dyeing effect and reduce the amount of chemicals. The advantage of this method is that it is gentle, non-toxic and easy to degrade, and conforms to the concept of green and environmental protection. However, the selection and application conditions of enzyme preparations require rigorous testing to ensure good results.

To sum up, the above three environmentally friendly dyeing technologies have their own characteristics and can all alleviate the environmental pressure brought by traditional dyeing to a certain extent. For complex multifunctional fabrics such as jacquard elastic cloth composite TPU, choosing a suitable dyeing solution should not only consider technical feasibility, but also take into account both economic and market demand.

In practical applications, environmentally friendly dyeing technology has been successfully applied to a variety of types of jacquard stretch cloth composite TPU fabrics, especially in the fields of high-end sportswear and medical protective supplies. The following is analyzing the actual effects of these technologies through specific cases.

Digital inkjet printing technology case

A well-known sports brand in Italy recently launched a series of running suits made using digital inkjet printing technology. This series uses jacquard stretch cloth composite TPU fabric, which achieves highly complex pattern design through digital inkjet technology. Compared with traditional dyeing methods,Technology reduces dye usage by 60%, while significantly reducing water and energy consumption. According to the brand’s internal evaluation report, this technology not only improves production efficiency, but also significantly improves the color vibrancy and pattern clarity of the product. In addition, the production cycle is greatly shortened due to the absence of plate making, making small batch customization possible.

Supercritical CO2 staining technology case

Another noteworthy application is on the protective clothing production line of a Japanese medical equipment manufacturer. The company uses supercritical CO2 dyeing technology to process its TPU composite fabrics. This method not only completely avoids the use of water, but also ensures the residual properties of the fabric because CO2 can evaporate quickly after the dyeing process. Studies have shown that the dye absorption rate of this dye method is as high as 98%, which is nearly 20% higher than that of traditional water bath dyeing. More importantly, this technology significantly reduces the amount of wastewater generated during the dyeing process, and reduces the wastewater discharge per square meter of fabric by more than 90%, greatly reducing the impact on the environment.

Bioenzyme treatment technology case

At a large home decoration company in the United States, bioenzyme treatment technology is used to pretreat the jacquard stretch fabric composite TPU fabric. By using specific pectinases and proteases, the company successfully removed impurities from natural fibers and improved the surface properties of synthetic fibers. This treatment not only improves the effect of subsequent dyeing, but also reduces the amount of chemicals used. Experimental data show that the dyeing uniformity of fabrics treated with biological enzymes has been improved by 30%, and the dyeing time has been reduced by 20%. Furthermore, since enzyme preparations are natural sources and are prone to degradation, the overall treatment process has extremely low environmental impact.

It can be seen from these practical cases that environmentally friendly dyeing technology has achieved remarkable results in the application of jacquard elastic cloth composite TPU fabrics. They not only improve the quality of products, but also greatly reduce resource consumption and environmental pollution in the production process, making important contributions to the sustainable development of the industry.
