On February 20th, the Beijing Winter Olympics was successfully concluded, and China's short-sliding team took a gold and silver, and the colorful speed slipper became a beautiful scenery of the game. The beautiful Chinese element pattern on the speed slippery is printed by Guangdong Derun Textile Co., Ltd. (hereinafter referred to as "Derun Textile") in Ronggui Street, Shunde District, Foshan City. De Run Textile R & D staff and time racing running, in just three years, it is the best results for the best results for my country's autonomous winter sports high-end competition.

Fabric research and development enhanced reduction effect

In Oct 2019, De Run Textile officially participated in the national key research and development plan "Science and Technology Winter Olympics" project "Winter Sports and Training Competition Research and Development Key Technology" project, and Beijing Jewelry College, Tsinghua University, Donghua University, Wuhan Institute of Physical Education , Anta (China) Co., Ltd. and other units joint research, making more technological content competition costumes. Among them, De Run Textile is mainly responsible for participating in two projects, one is a key technology research and preparation application of winter sports racing projects, including short-track speed skating project costumes, speed skating projects and alpine ski project costumes. The other is the key technology research and preparation application of winter sports skills projects, including pattern skating project costumes, free-style skiing aerial tips.

As a country with a relatively short history of ice and snow, most of my country's winter sports high-end contests rely on imports. He Hanwei, a weaving development engineer of Guangdong Derun Textile Co., Ltd., introduced the independent research and development system of high-tech and cutting-edge competition clothing in China, and the team's research and development needs from scratch, step by step to explore the problem. In the development and production of the game clothes, Derun textile has conducted various process trials and adjusted. For speed skating, DR Run Textiles have prepared more than a dozen fabrics for projects during the research and development of nearly three years. After the wind tunnel test, there are four new fabrics to increase 10%, and there are two events that are ultimately selected in the contest in winter speed skating.

The selected fabric uses special weaving structural design and fine digital printing processes to meet the requirements of reduction and moisture absorption. High-speed ice is sliding, which needs to confront air resistance equivalent to the wind. He Hanwei said that the pit structure on the fabric effectively enhances the displacement of clothing, helping athletes to fight for faster time. On September 26, 2021, China's speed slide team member Gao Tingyu wore test suits made from Derun Textiles, which were developed by Derun Textiles in China Cup, broke his personal skating man 500 meters nationwide. Record.

In order to maintain the pit structure of the fabric, the moietual textile continuously improves the production process. "The fabric consists of yarns, which is elastic, it is difficult to fix the shape." He Hanwei said that the project team overcome difficulties in the weaving process, stabilize the size, height, and ensuring the quality of the fabric. In addition, De Run Textiles have prepared nearly 10 fabrics for the alpine skiing competition, mainly emphasizing the reduction resistance and unidirectional moistureing performance; developing and selecting six fabrics for the pattern skating contest, which has advantages in elasticity, gloss, and quality. It is used in a multi-game match for the 2021 season; to optimize the water-resistant breathable performance and elasticity, so that the athletes will remain flexible when doing air.

Printing process to achieve accurate positioning printing

The "shirt" of the China Short Track Skater is printed with rich traditional cultural elements, lifelike dragons, symbolizes auspicious wishful pattern to leave a deep impression of the audience before the TV. De Run Textile is responsible for the printing of the "shirt" pattern. Li Mei, manager of the company's printing and production department, to overcome various difficulties to harvest satisfactory results. Short-track speed slippery anti-cutting fabric printing process, should pay special attention to the flatness of the layout, bright color, the color depth, pattern line fineness, exact degree accuracy, gradient natural transition effect, color fastness Also guarantees that the elasticity and anti-cutting properties of the fabric are not lost. Derun textile repeated trial, the special treatment process reached printed requirements.

In the printing of the speed skating contest, De Run Textile broke through the precision positioning printed problem. Li Mei said: "Complete the task that is impossible to complete." The athlete of the speed skating suit will appear in the high position of the arm. In order to ensure that the Pentagon pattern is accurate, the De Run Textile R & D team takes more than two months to conduct technical research, and finally find a feasible precision positioning method. "Each athlete is different, it needs to be customized. Plus the operation on high-elastic jacquard fabrics, it is easy to position," Li Meiju said, the company improves the printed process, and makes it accurate Pattern effect.

In order to ensure the high precision of the pattern, the De Run Textile is printed with a 12-color digital printing machine. The printed process is more, the process is long. Digital printing can reduce the multi-way process of traditional printing, reduce energy consumption, better printed effect. Li Mimei said that the printing process is a systematic engineering that can make good products under advanced equipment, high hard technology, rich experience in multiple effects.

It is understood that De Run Textile is a super century-old silk factory, which has been transformed into a chemical fiber knitted flexible fabric in 1990, which is in a leading position in the domestic elastic fabric segmentation industry. De Run Textile has conducted in-depth research in color pattern, and fabric structure, and has accumulated rich experience. The company will conduct technical transformations each year, in response to market demand or some special processes, launch 8-10 R & D projects to improve their technology innovation capabilities.
