On February 5, the Chinese team won its first gold medal at the Beijing Winter Olympics with a 0.01 second advantage in the short track speed skating mixed relay. On February 7, the Chinese team won gold and silver medals in the men’s 1,000-meter short track speed skating. The athletes of the Chinese team were so graceful and graceful on the field that their wonderful performances were breathtaking! But did you know that the “ice and snow uniforms” they wear are inseparable from the hard-core strength of Shunde Intelligent Manufacturing! This set of “ice and snow suits” with unique Chinese cultural characteristics and independent research and development technology is full of technological content and full of design! Recently, all-media reporters from Guangzhou Daily walked into Shunqi behind the “battle uniform”.
Bonding: Behind the “Ice and Snow Suit”, Ronggui Enterprises helps
The Beijing Winter Olympics are in full swing, and the ice and snow competitions of Chinese Winter Olympic athletes have left a deep impression on everyone. It is worth mentioning that the “ice and snow uniforms” of the Chinese team athletes in the speed skating event are inseparable from the help of a company in Ronggui, Shunde.
Time goes back to October 2019. At that time, Guangdong Derun Textile Co., Ltd. began to participate in the Ministry of Science and Technology’s national key R&D program “Science and Technology Winter Olympics” key project “Key Technologies for Research and Development of High-Performance Clothing for Winter Sports and Training Competitions”, and cooperated with Beijing Institute of Fashion Technology, Tsinghua University, Donghua University, Wuhan Institute of Physical Education, ANTA (China) Co., Ltd. and many other units have jointly researched and used technology to help prepare for the Winter Olympics.
It is understood that the predecessor of this company is a silk factory with a history of over 100 years. At present, the company is my country’s largest professional manufacturer of chemical fiber elasticspandex fabrics, mainly producing stretch swimwear, underwear and sportsclothing fabrics. The company has successively won many national and provincial honors such as “National High-tech Enterprise”, “Guangdong Enterprise Technology Center”, “Guangdong Spandex Elastic Fabric Engineering Technology Research Center” and “CNAS National Accreditation Laboratory”.
“On the one hand, as a leading company, we have received joint recommendations from many units; on the other hand, we provide fabrics and products for the Winter Olympics speed skating national team. This screening process is also very strict.” Talking about getting involved in the Winter Olympics R&D project, He Jiyu, the person in charge of the company, told reporters. It is understood that in 1985, after graduating from university, He Jiyu came to the company and witnessed the company’s transformation and upgrading process. “Since the 1990s, we have transformed into stretch knitting. In the field, the products are mainly exported. Driven by the dual cycle, the proportion of domestic sales of products has gradually expanded.”
Hardcore:
Independently research and develop “ice and snow suit” fabrics to fill the gap in the industry
It is understood that before 2019, most of China’s winter sportswear relied on imports. Therefore, independent research and development of Winter Olympics “ice and snow uniforms” has become the most urgent need for the Chinese ice and snow army. .
In 2019, after layers of selection, Derun Textile had the opportunity to participate in the design and production of Winter Olympics competition clothing. Xie Nanping, manager of the technology development department of the company, said that during the nearly three-year research and development process, the company had prepared more than a dozen fabrics for speed skating through various process tests and adjustments. After wind tunnel testing, four of the newly developed fabrics have a 10% increase in drag reduction compared to previous race suit fabrics. Two of them were eventually selected to be used in the Winter Olympics speed skating competition uniforms.
Like speed skating, short track speed skating is also about winning in millimeters. Since high-speed skating on ice requires fighting against air resistance equivalent to more than ten levels of wind, speed skating clothing has high requirements for anti-cutting and drag reduction. In this Beijing Winter Olympics, the “dragon suits” worn by the short track speed skating team members (the competition uniforms have a dragon pattern printed on them) are of highquality It has excellent anti-cutting and drag-reducing effects, and its anti-cutting strength is 15 times that of steel wire.
It is understood that after testing, the performance of the moisture-absorbing and drag-reducing fabric produced by this company has reached or exceeded the level of similar foreign fabrics, and it was selected by the national speed skating team as competition clothing fabric. At the same time, special fine patterns were printed for the anti-cutting competition uniforms of the national short track speed skating team. The lightweight and mesh fabrics produced by this company are selected by the national figure skating team as competition clothing fabrics. According to reports, Derun Textile has invested a total of 18 million yuan in the “Technology Winter Olympics” project.
“Before 2019, my country’s Winter Olympics equipment was basically imported, and the supply of fabrics and the production of clothing were at a blank state domestically.” He Hanwei, the main person in charge of the technology development department of the company, is the “Technology Winter Olympics” One of the core personnel of the key project, he told reporters that the team started from scratch, purchased foreign fabrics for research, and collaborated with universities to conduct various experiments. “In the end, we found that the smoother the fabric, the smaller the resistance. The dimpled structure has a stronger resistance reduction ability.” After wind tunnel testing, the dimpled fabric became the original fabric for the “suit” of the Chinese Winter Olympics speed skating team.
It is reported that the development process of the fabric was extremely difficult, and it took the team three years of hard work to achieve success. He Hanwei recalled that since the launch of the project, the company’s R&D team has traveled to Beijing many times to discuss product development with relevant project partners. “The epidemic…�, we can only hold a video conference once a week. After each meeting, everyone will work non-stop to implement their suggestions for improving the fabrics. After the fabrics are made, they will be sent to Beijing immediately for continuous improvement, striving to make the final fabrics and products perfect. . “It is reported that the fabrics provided by the company for the Chinese team athletes in the Winter Olympics speed skating event are mainly used in sleeves and legs.
Printing and dyeing: Overcoming various difficulties, the patterns are beautifully printed
The “ice and snow uniforms” of the athletes of the Chinese speed skating team, with red and black gradients, the five-star red flag and the image of the Chinese dragon, are vividly displayed. However, at the beginning, when the graphic design draft was placed in front of Li Meiju, manager of the printing production department of the company, she encountered difficulties. “It is very challenging to print the printing pattern exactly on the stretch fabric. “She said that during the printing process of cut-resistant fabrics, special attention should be paid to the flatness of the cloth surface, the brightness of the colors, the depth of the color, the fineness of the pattern lines, the accuracy of pattern alignment, the natural transition effect of gradient colors, and the color fastness , but also to ensure that the elasticity and anti-cut performance of the fabric are not lost.
According to reports, the exquisite patterns on the “Ice and Snow Suit” are all printed by a 12-color digital printing machine. This equipment is at the advanced level in the world. “Advanced equipment, coupled with special printing process design, breaks through the color registration limitations of traditional textile printing and dyeing patterns, and has unique advantages in printing high-precision three-dimensional patterns such as color gradients and moirés,” Li Meiju said.
The reporter saw in the production workshop that the digital printing machine performed exquisite printing steps under the operation of workers. It is worth noting that the “ice and snow uniform” is tailor-made according to the athlete’s body shape. “Although the size of the ‘suit’ is different, the location of the pattern is roughly the same. This also benefits from our precise and mature printing technology.” .”
“The particularity of the raw materials of cut-resistant fabrics, coupled with the very high requirements for fineness of patterns on clothes, makes the dyeing and finishing process very difficult. However, we have overcome a large number of problems one by one, so that the task can be successfully completed.” Li Meiju said , through the use of special printing technology, the above requirements are taken into account, and it can also meet the requirements of subsequent garment processing and surface drag reduction design.
Smart manufacturing in Shunde shines in the Winter Olympics. He Jiyu said that in racing competitions, 0.01 seconds may determine the ownership of a gold medal. This 0.01 second difference may come from clothing and equipment. In the future, he will continue to improve his research and development capabilities and use powerful technology to help China’s ice and snow sports continue to achieve new breakthroughs. .
