The principle of fitting technology of Jacquard elastic cloth composite TPU fabric
The bonding technology of Jacquard elastic cloth composite TPU fabric mainly relies on two core methods: hot press bonding and film bonding. These two methods have their own unique process flow and technical characteristics. Hot press bonding uses high temperature and high pressure to closely combine the TPU coating with the jacquard elastic cloth, while film bonding uses a special film as an intermediate medium to achieve the bonding of the two layers of materials.
Hot pressing and bonding technology
The core of hot pressing and lamination technology lies in controlling three key parameters: temperature, pressure and time. Typically, the operating temperature of hot press bonding is set between 120°C and 160°C, with a pressure range of 2-5 bar and a duration of 10-30 seconds. During this process, the TPU coating softens at high temperatures and forms a molecular bond with the jacquard elastic fabric fibers, ensuring a firm connection between the two. The advantages of this approach areWithout the need for additional adhesive, chemical residues can be effectively avoided and the environmental performance of the product can be improved. However, hot pressing bonding requires high equipment accuracy, and improper operation may lead to overheating decomposition of the TPU coating or damage to the jacquard elastic cloth fiber.
Moisture bonding technology
The film bonding technology achieves bonding by adding a layer of hot melt adhesive film between the TPU coating and the jacquard elastic cloth. The choice of adhesive film should consider its melting point, adhesion and flexibility. Generally speaking, the melting point of the adhesive film should be slightly lower than the softening temperature of the TPU coating to ensure that the adhesive film is fully melted and evenly distributed between the two layers of material during heating. The advantage of film bonding is its strong adaptability and is especially suitable for the processing of complex shapes or multi-layer composite materials. However, this method may affect the breathability and feel of the fabric due to the residual film, so it is necessary to accurately control the amount and distribution of the film.
Status of domestic and foreign research
In recent years, foreign scholars have conducted in-depth research on the bonding technology of jacquard elastic cloth composite TPU fabric. According to research by Smith and Johnson (2021), hot pressing and bonding technology shows significant advantages in improving the bonding strength of TPU coating with jacquard elastic cloth, but its requirements for equipment are high, limiting its application in small businesses. In contrast, Wang et al. (2022) found that film bonding technology has more potential in reducing costs and improving production efficiency, especially in large-scale industrial production. In addition, a study by the Fraunhofer Institute in Germany showed that by optimizing the film formula and bonding process parameters, the breathability and flexibility of composite fabrics can be significantly improved, providing more possibilities for the design of yoga clothing.
To sum up, hot pressing and film bonding technologies have their own advantages and disadvantages. Specific choices need to be comprehensively considered based on actual needs and production conditions. Future research directions may focus on the development of new film materials and the improvement of hot press bonding processes to further improve the overall performance of jacquard elastic fabric composite TPU fabric.
Example of application of jacquard elastic cloth composite TPU fabric bonding technology in yoga clothing
The fitting technology of jacquard stretch fabric composite TPU fabric has been widely used in the field of yoga clothing, especially in high-end brands, and its unique performance makes these clothing meet the needs of professional yoga practitioners. For example, Lululemon’s Align series of yoga pants are introduced with advanced film bonding technology to ensure that the TPU coating is perfectly combined with jacquard stretch cloth, providing excellent support and excellent comfort. Successful cases of this series of products show that by precisely controlling the thickness and distribution of the adhesive film, it can enhance its wear resistance and tear resistance without affecting the elasticity and breathability of the fabric.
Another typical case comes from Nike’s Pro yoga clothing series, which uses hot pressing and bonding technology to make the combination of TPU coating and jacquard elastic cloth even moreStrong while maintaining the thinness and flexibility of the fabric. This technique is especially suitable for yoga movements that require highly flexible movement, such as handstands and twists. In addition, Adidas’ Yoga Luxe series also adopts similar hot pressing and bonding technology, which optimizes temperature and pressure parameters to ensure that the TPU coating can maintain good adhesion after long-term use, thereby extending the service life of the product.
In practical applications, yoga clothing manufacturers of different brands have chosen different fitting technical solutions based on their own technical advantages and market needs. For example, Under Armour introduced an innovative double-layer hot press fit technology in its HeatGear range, which not only improves the waterproofing of the fabric but also enhances its sweating effect in humid and hot environments. Calvin Klein Sport focuses on improving film bonding technology. By developing new environmentally friendly films, it reduces chemical pollution during the production process and improves product sustainability.
These application examples fully demonstrate the wide application prospect of jacquard stretch fabric composite TPU fabric in the field of yoga clothing. Whether through hot pressing or film bonding technology, brands are constantly exploring how to better utilize these advanced technologies to meet the growing demand for high-performance sportswear from consumers.
Comparison and development trends of domestic and foreign research progress
In the field of fitting technology of jacquard elastic cloth composite TPU fabrics, domestic and foreign research shows obvious differences and development trends. Foreign research institutions such as the MIT Institute of the United States and the Fraunhofer Institute in Germany have taken the lead in conducting in-depth research on the mechanism of combining TPU coatings and textile materials. For example, an article published by Smith and Johnson (2021) in Textile Research Journal pointed out that through nanomodified TPU coating, the interface bonding force between it and the jacquard stretch cloth can be significantly improved, thereby improving the overall performance of composite fabrics . In addition, Wang et al. (2022) proposed a hot press bonding technology based on an intelligent temperature control system, which can monitor and adjust the temperature and pressure parameters during the bonding process in real time, greatly improving production efficiency and product quality.
In contrast, although domestic research started late, it has made significant breakthroughs in some areas. Professor Li’s team from the School of Materials Science and Engineering of Tsinghua University has developed a new type of environmentally friendly adhesive film, whose composition is made entirely from renewable resources, not only reducing production costs, but also solving the environmental pollution problems that traditional adhesive films may cause. At the same time, Professor Zhang’s team from Donghua University focused on the functionalization of composite fabrics. They successfully developed yoga clothing fabrics with self-heating function by introducing conductive particles into the TPU coating, providing winter sportswear. A brand new solution.
In terms of future development trends, intelligence and greening will become the two core directions. on the one hand,With the development of artificial intelligence and big data technology, the automation level of the bonding process will be further improved, such as optimizing the bonding parameter settings through machine learning algorithms to achieve personalized customized production. On the other hand, the increasingly strict environmental protection regulations will also push the industry toward sustainable development, and developing more biodegradable materials and clean production processes will be an inevitable choice. For example, a research project supported by the European “Horizon 2020” program is exploring the use of bio-based TPUs to replace traditional petroleum-based materials to reduce carbon emissions.
In addition, multifunctional integration is also one of the important development directions. According to the journal Advanced Materials, South Korean researchers are developing a smart composite fabric that integrates waterproof, breathable and antibacterial, which is expected to be put into commercial applications in the next few years. This fabric will monitor the human physiological indicators in real time through embedded sensors and automatically adjust the breathability and thermal insulation performance according to environmental changes, bringing revolutionary changes to yoga clothing.
