It now integrates an industrial chain integrating chemical fiber, yarn, weaving and finished products. In recent years, Jinjiang’s textile and garment industry has been continuously upgrading to high-end, intelligent and green. Facing the requirements of the new era, how to transform more and better scientific and technological achievements into practice and lead the textile and garment industry with highquality through scientific and technological innovation Development has become a topic of greatest concern to the industry.
High technology in fabrics
“The shirt can be machine washed easily, shake it out after washing and it will be as smooth as new…” “It can rebound quickly even after sitting for a long time, and its wrinkle resistance is 4 times stronger than ordinary fabrics. It is easy to take care of and easy to wear!” Recently, Lilang and Jiumuwang have launched functional new products one after another. Through continuous innovation in fabrics and tailoring, shirts and trousers have become easier to care for and more comfortable.
In the context of a new round of industrial transformation and consumption upgrading, technological innovation has become a high-frequency word in the development planning of clothing companies. More and more clothing brands are researching and exploring functional fabrics to make fabrics “technical”. In fact, this is also the direction of the textile industry.
“Technological innovation in the textile industry focuses on high-quality development, fully demonstrating the trend of the textile industry transforming into high-end, intelligent, and green. New fields and new tracks are constantly being opened up, and the industrial chain and innovation chain are more closely integrated.” GM. Said Ma Yongmei, deputy general manager of High-TechNew Materials Group Co., Ltd., party secretary and general manager of General Technology China Textile Science Research Institute Co., Ltd.
Zhu Meifang, academician of the Chinese Academy of Sciences and dean of the School of Materials Science and Engineering of Donghua University, said that the textile industry has the ability and potential to further transform demographic advantages into development advantages and market advantages, and textile technology must also make up for it. The textile industry is an important promoter of global sustainable governance. The industry should actively apply green technology, promote green consumption, improve green standards, and continue to promote the green transformation of the entire industry chain upstream and downstream.
Fengzhu Textile recently signed a key technology development agreement with the Haixi Textile New Materials Industrial Technology Jinjiang Research Institute and the China Textile Research Institute (Tianjin) Technology Development Co., Ltd. on the preparation of bio-based polylactic acid PLA/polyester PTT composite elastic fiber and its fabrics. and Application Cooperation Agreement.

More than just warmth and beautification
Regarding the functionality of fabrics, textile companies are making efforts from different directions.
With the continuous improvement of people’s living standards and the environment, people have put forward higher requirements for the performance of flame-retardant textiles. Promoting the progress of flame retardant technology will not only form a strong protection for the people, but also form a new economic growth point.
“Traditional textiles are only used to keep warm, cover ugliness and beautify, and what we do is to make textiles have more functions, such as health functions.” Lianyungang Du Zhong XinaoshenSpandex Co., Ltd. General Manager Zhang Bin told reporters that deodorizing, antibacterial, rebound and other products have been the direction of the company’s efforts in recent years.
Among them, Aoshen deodorizing spandex is favored by the market. According to reports, Aoshen deodorizing spandex adds a deodorizing functional body to the spandex polymer to increase the deodorizing performance of the fiber while maintaining the excellent properties of spandex. Fiber reduces and eliminates odors in fabrics or the environment through physical and chemical adsorption of odor components, thereby purifying the living environment and keeping clothing odor-free and comfortable to wear. “Our products are washable. Even after being washed 50 times, the deodorizing performance retention rate of spandex is still over 90%,” Zhang Bin said.
In addition to deodorizing spandex, GRS environmentally friendly recycled spandex is also the company’s flagship product. It is reported that the recycled material ratio of GRS environmentally friendly recycled spandex is 100%. For products with other recycled material ratios (ranging from 20% to 100%), customized production can be achieved.
According to Cui Huashuai, a professor-level senior engineer at the Innovation Center of China Textile Institute, a complete set of industrialized technology for the preparation of high-strength and controllable PGA/PGLA fiber has been developed through homogenized melt preparation and degradation performance control. The overall technology has reached the international advanced level. The project achieved a technological breakthrough in the engineering technology of absorbable sutures for surgical operations, targeting skin defects.The application technology development of products such as artificial dermal substitute support nets for patients with damaged tissue, absorbable tissue reinforcement materials for tissue hemostasis and leakage prevention, and cardiac occluders for left atrial appendage diseases has opened up new application fields for absorbable fibers.
“The continued research and development of medical device products has opened up new application areas for absorbable fibers, which is of great significance to the upgrading of my country’s medical products and ensuring the safe development of the medical industry.” Cui Huashuai said that polyglycolide is a structural The simplest aliphatic polyester has the advantages of excellent biodegradability, good biocompatibility, excellent gas barrier properties, high mechanical strength, and good chemical stability. “It can be degraded into carbon dioxide and water and is an environmentally friendly polymer material with great development prospects.”
“The absorbable suture production industry chain is long and interdisciplinary. At present, there is a lack of core technology in China. The main production mode is still importing group threads from abroad, and only assembly is done. .” Cui Huashuai said that judging from the current product share in the domestic market, the domestic rate is less than one-third.
Cross-border technology application
Due to the increasing depletion of petroleum resources and the influence of factors such as advocating nature, health and environmental awareness, people’s attention has gradually turned to regenerated fibers. As a type of regenerated fiber, products woven from Lyocell fiber can be completely decomposed in the soil, and the amine oxide solvent used in production is non-toxic, pollution-free and recyclable. The entire fiber production process is environmentally friendly and the solvent is recycled. The efficiency can reach more than 99%. Therefore, Lyocell fiber is also called “21st century green fiber”.
“In the development of green fiber Lyocell/polyimide fiber blended yarn, we are exploring Lyocell/polyimide blended yarn with different polyimide addition amounts in 30s, 32s, and 40s Development. Through the optimization of the spinning process, polyimide has many excellent properties such as antibacterial and far-infrared when the addition amount is 7%. Combined with the soft, skin-friendly and comfortable characteristics of lyocell fiber, it is suitable for the development and development of close-fitting textile products. application, the market prospect is broad.” said Fang Di, director of the Product Development Department of Zhongyuan Branch of Xinxiang City (China Academy of Textile Sciences).
“We are wondering whether we can give the product more functionality based on green fiber.” Fang Di said that although the development prospects of polyimide are good, it is still based on raw material prices and insufficient research on spinnability. Factor, the product has not yet been promoted.
In terms of antibacterial function, Fang Di believes that the antibacterial properties of textiles can be divided into two categories, namely intrinsic antibacterial and post-processing antibacterial. Among them, natural antibacterial fibers have certain antibacterial properties, but the antibacterial properties of different materials vary greatly. In addition, there are some problems such as poor elasticity and poor comfort after being made into textiles, which still cannot satisfy consumers’ requirements for functionality and comfort. The dual demands of sex.
“In addition to natural antibacterial fibers, we can give textiles antibacterial properties by adding antibacterial agents and finishing.” Fang Di said that natural plants The ingredients of antibacterial agents are relatively complex, and the cost of natural animal antibacterial agents is relatively expensive, while organically synthesized antibacterial agents have a certain degree of toxicity, and inorganic antibacterial agents have some safety hazards. “In comparison, graphene materials have development potential. .”
Wang Yuping, director of the National Advanced Functional Fiber Innovation Center, pointed out that the research and development of green, differentiated, multi-functional and intelligent high-quality flame-retardant fibers and products will help my country’s industrial development pattern and industrial boundary adjustment and the cross-integration of multi-disciplines and multi-technologies. It is of strategic significance to promote the research, development and application of high-tech flame retardant materials in our country. With the continuous increase of human safety awareness and the continuous improvement of flame retardant regulations, the development of flame retardant textiles will continue to increase, especially intrinsic flame retardant fibers will become a new hot spot in the market. Long-lasting environmentally friendly high-quality flame-retardant fibers, functional composite flame-retardant fibers, green and environmentally friendly flame-retardant fibers, comfortable flame-retardant fibers, high-tech flame-retardant fibers, etc. will become the main sources of flame-retardant modified polymer fibers. research direction.
Pan Shenhong, founder of TEA. Textile Intelligence and postgraduate tutor at Donghua University School of Fashion, believes that future enterprise development can take four paths. The first is to be faster, more economical, and good goods are not expensive; the second is to use better products. materials to empower consumers; the third is sustainability, especially now that European and American orders have high sustainability requirements; the fourth is differentiated design. “If a brand wants to continue to develop, it will put forward higher requirements for materials. It needs to have the accuracy to grasp the market, differentiation from other brands, and sufficient cost-effectiveness.”
