Abstract: Embroidery is a method of decoration on the surface of finished fabrics, which has a certain aesthetic value. As one of the most commonly used development technologies in the field of smart textiles, embroidery technology has great application value in smart textiles because of its excellent personalized customization function, process reproducibility and production efficiency. In recent years, with its unique processing advantages, embroidery technology has provided increasingly extensive research and development ideas for wearable devices, flexible electronic fabrics and other products, so it has been widely studied and applied in signal identification and transmission, biosensor and physical sensing.
At present, with the gradual expansion of the smart wearable field in the market, flexible fabrics already have the functions of signal recognition and signal transmission. Compared with most fabric processing technologies, embroidery technology is remarkable in Tailored Fiber Placemen (TFP) function, which gives it an advantage in the preparation of flexible electronic tags and signal transmission lines. In terms of biosensors, embroidery technology has been one of the main methods to prepare fabric ECG electrodes and EMG electrodes. Users only need to wear smart textiles with integrated biosensors, and the sensors will be located in the corresponding monitoring position. The use of embroidery instead of weaving or knitting can make the design and shape of the electrode more personalized, so that it can adapt to different applications and monitoring scenes. Therefore, embroidery technology has high application potential in the field of intelligent wearable to monitor human bioelectric signals. Textile sensors can provide the evaluation of general parameters such as pressure, stress, temperature and humidity, and have great application value in structural monitoring and medical and health care. At present, many scholars at home and abroad have made good physical sensors such as stress sensor, temperature sensor and pressure sensor through embroidery technology. Embroidery has other important applications in the field of smart textiles, such as physiotherapy textiles and temperature-adjusted textiles.
Intelligent textiles are a new product in the interdisciplinary research field. In addition to transmission and sensing functions, smart textiles have the structural characteristics of being multiple, multi-dimensional and multi-scale, but also show the characteristics of light weight, low modulus and skin affinity. With its unique processing advantages, embroidery technology provides more extensive research and development ideas for wearable devices, flexible electronic fabrics and other products, so it is used in intelligent textile research in various fields.
At present, the application of embroidery technology in smart textiles has great potential, not only with powerful personalized customization and convenient fabric surface beautification and decoration, but also with good process reproducibility and structural dimensional stability, which can ensure the rapid prototyping of designed products and promote the quantitative production of new intelligent textiles. However, there are still some problems in the application of embroidery technology in smart textiles, such as the undiversified supply of conductive embroidery thread, insufficient applicability of printing software to intelligent textile design, and so on. The most important thing is to promote cooperation among embroidery and medicine, electronics, communications, materials, textiles and other disciplines, and constantly enhance and improve the functionality and practicability of the products. For this reason, it is necessary to strengthen the research and development of conductive yarns for embroidery, to study embroidery printing software and embroidery devices suitable for the design of intelligent textiles, and to promote cross-cooperation between embroidery technology and other fields.
