They can perceive environmental changes and react accordingly. They play an important role in improving the quality of life, improving working conditions and meeting the needs of special industries.

In recent years, intelligent textile materials, such as intelligent temperature regulation, shape memory, intelligent discoloration and electronic information, are developing from the field of wear and wider.

Intelligent temperature regulating textile materials

This intelligent textile material has been selected as one of the 21 innovations to change human life in the twenty-first Century. It has super practicality and applicability.

At present, the technology of intelligent temperature regulating textiles is developing towards high performance, high technology level and large-scale industrialization. The technology research and development, clothing design and operation convenience design of smart textiles constantly meet the needs of human beings for intelligent products.

With the introduction of the 4 concept of German industry and the CPS intelligent system of the United States, foreign countries have been relatively mature in product technology research and development and industrialization.

The new intelligent thermoregulating diving suit SmartSkin, its outer layer is obturator neoprene foam material. The interlayer is a composite of thermosensitive hydrogel and open polyurethane foam. The Triangle company of the United States has synthesized a microcapsule of 15~40 micron diameter. The microcapsule has the function of heat absorption and heat, and the fabric has the function of temperature regulation. The scientists of Portuguese nanotechnology and intelligent materials center (CeNTI) have developed a nano microcapsule made of starch and contains trace wax substance, which can be permanently attached to clothes. With the change of human body temperature, the microcapsule will absorb heat, melt or exotherm and solidify, thus maintaining the temperature of human body in a comfortable range. The PCM (phase-change) technology of Outlast has been widely applied in the United States and the United Kingdom, and Mid6 technology has developed a kind of technology.

Intelligent temperature control textiles in China

R & D and application have made great progress. Some domestic enterprises have developed many kinds of intelligent temperature regulating textiles through different technical means.

The DuPont Co has used Outlast phase change material microencapsulation technology to produce knitted fabric with temperature adjustment function, and made "Fountian" brand temperature responsive smart clothing. Heng Tian Hai Long Limited by Share Ltd and Tianjin University of Technology have used microcapsule technology to develop high temperature phase change material microcapsule and high heat storage heat regulating fiber with heat storage and heat release bidirectional temperature adjusting function, which has been developed by microcapsule technology. It has realized the connection of heat, heat storage and thermal insulation, and improved the flexibility of the human body after wearing winter clothes. The international group and Hebei Xiong Textile Group jointly designed the phase change intelligent thermoregulation textiles by combining the space phase-change temperature adjusting fiber with the imported advanced Luo Ke cashmere, and also introduced the first "warm winter and cool summer" performance in China. For example, Hongkong Futian industrial group and the United States.

。

China has already begun to build a large scale manufacturer, and has formed an intelligent textile material market.

For example, Qingdao snow Group Limited, Qingdao Yi Quan knitted garments Co., Ltd. and Qingdao Rong Hai Garments Co., Ltd. have jointly developed the intelligent temperature regulation fiber business casual wear, and have achieved mass production, and have good domestic and foreign competitiveness.

But China's intelligent temperature control textile

Research and development started late. On the one hand, there are still many outstanding problems in product development, such as immature technology, difficulty in processing, poor durability of clothing and insufficient product performance; on the other hand, the combination of technology development and industry is relatively weak, leading to the application of intelligent temperature control textile materials is lagging behind, and in the stage of product exploration and development, there is no large-scale production.

Intelligent shape memory textile materials

Intelligent shape memory textile materials achieve the following 3 objectives: the design of green materials, the development of high memory products and the mass production of products are the main development directions of shape memory textiles.

The research on shape memory textiles abroad started earlier, and the market scope is large, the overall technology level is high, the data source is abundant, and the intelligence level is high.

At present, great progress has been made in the study of shape memory fibers in Japan, the United States, the United Kingdom, Italy and Holland.

In order to achieve the goal of scald prevention, a new type of polyurethane material, Diaplex, which has the shape memory function has been developed. A new polyurethane material, shape memory function, has been developed. It has not only exhibited high water repellency, but also can respond intelligently to the heat released by the wearer through the control of heat release. It is suitable for manufacturing multi-functional smart clothing with shape memory and heat dissipation and water vapor channels at high ambient temperature. Currently, commercialized products of such materials, such as smart sportswear and mountaineering clothes, are available in. For example, when the British textile organization is developing anti scalding clothing,

Some domestic enterprises or research institutes have made great progress in the research and application of intelligent shape memory textile materials.

For example, Tianjin University of Technology used post-processing technology to process fibers and designed thermo induced shape memory fibers. The shape memory research center of Hong Kong Polytech University invented the cellulose based shape memory textiles, and deeply studied the influence of the composition and structure of smart shape memory fibers on shape memory temperature, restoring force and memory effect. It played an important role in the research of thermosensitive shape memory polymers and shape memory films.

Compared with foreign enterprises, there are many researches on shape memory textile materials in China, but most of them are in the experimental stage. The materials are single, and the overall innovation is not enough. Most of them are tracking research. Many new varieties are still being developed, and large-scale industrial production has not yet been realized.

At the same time, there are some problems, such as relatively weak talent team, weak competition, less investment and insufficient development. Besides, there is a lack of knowledge about new technologies such as sharing technology and intelligent technology, and there is still a long way to go to realize the industrialized production of shape memory textiles in China.

It is an intelligent product with high added value and high efficiency, and has a good development prospect in textile, military, entertainment, anti-counterfeiting and other fields.

The technology of intelligent color changing textiles is developing towards high practicability, high safety and high intelligence. The structural design, functional design and intelligent design of color changing fiber meet the needs of product application in an all-round way.

At present, the research and development technology of smart color materials can be divided into 2 main categories. One is the direct research and development of color changing fibers, such as post finishing technology and graft polymerization technology.

At present, some developed countries in China and other developed countries have realized the research and development of the above 2 technologies, but there is still a big gap between them in terms of technology level and developed countries.

In terms of manufacturing technology level, domestic enterprises are mostly in the initial stage.

Foreign market sales of intelligent products have been achieved.

With the support of NASA technology, the sportswear, which is now in the market, is called Radiate. It can change the way of photon reflection according to the heat emitted by the body, and the heat emitted by the body is different. The color of the corresponding parts of the clothing will be different.

The biggest function of the smart color changing sportswear is to enable users to see the fever of muscles in real time, adjust different motion strategies, and realize the combination of intelligent products and human motion.
