The 2022 Beijing Winter Olympics will have a total of 7 major events, 15 sub-events, and 109 small events, resulting in a total of 109 gold medals. Ice and snow athletes have shown their talents in various events. The successful holding of the Beijing Winter Olympics has a unique role in promoting high-quality development, guiding cutting-edge technology, promoting the integration of culture, sports and tourism, building a healthy China, and building a new development pattern. The textile industry is an innovation-driven technology industry, a culture-led fashion industry and a responsibility-oriented green industry, which coincides with the concept advocated by the Beijing Winter Olympics. In the Beijing Winter Olympics, textile elements are everywhere. Therefore, this issue has specially set up the special topic "Textile Power at the Winter Olympics" to help readers perceive the charm of the industry and seize market opportunities. This issue will introduce textile elements related to event guarantees at the Beijing Winter Olympics.

Graphene heating backpack

In winter environments, graphene materials play a huge role. It is reported that the low-temperature environment graphene intelligent heating products and thermal protection application technology developed by Beijing Innovation Aishangjia Technology Co., Ltd. (hereinafter referred to as "Aijia Technology") and Beijing Graphene Technology Research Institute Co., Ltd. In order to meet the thermal requirements of personnel and on-site professional equipment in the environment, breakthroughs in key technologies such as low-temperature start-up and operation of graphene flexible fabric heating materials, rapid electro-thermal conversion, etc., realize low-temperature application of graphene flexible fabric heating technology.

Beijing International Cloud Broadcasting Technology Co., Ltd. undertook the high-definition video cloud broadcast work of the Winter Olympics. Among them, the security work in the Zhangjiakou competition area requires the staff to carry a "cloud broadcast backpack" and use Aijia Technology's graphene heating device. The broadcast equipment can be turned on normally at minus 20°C.

smart bed

The Beijing Winter Olympics Organizing Committee has specially equipped athletes with smart beds that can be controlled intelligently, which once made American bobsleigh athlete Summer Britcher full of praise on his social platform.

It is understood that the smart bed is 1.2 meters wide and 2 meters long by default, and can be adjusted in height, hardness and length. In terms of length, the smart bed takes 20 cm as a step, and the maximum can be adjusted to 2.4 meters; in terms of height, the height of the head and foot of the bed can be adjusted separately; in terms of hardness, in addition to memory foam mattresses, some coconut palms are also prepared. Mattresses to meet different needs. The smart bed can take care of the athlete's spine. It only needs to be set to a suitable sleeping angle by remote control, and the memory foam and smart sensors in the mattress can provide massage and other services for the athletes. Not only that, if the sleeping position is uncomfortable and the athlete snores, the smart bed can also help adjust the height of the head for relief.

Filter products

The prevention and control of the new crown pneumonia epidemic is of great significance, so how to ensure the breathing safety of the personnel at the Winter Olympics? With the full application of air disinfection machines, intelligent robots are distributed throughout the venues to carry out cleaning and sterilization, mobile temperature measurement, epidemic prevention supervision, etc., which greatly ensures the quality of epidemic prevention in the competition venues and living environment. Whether it is an air sterilizer or an intelligent robot sterilizer, a large number of industrial textiles and non-woven materials are used, which play core roles such as filtration and dust removal.

underarm bandage

This Winter Olympics has launched a variety of anti-epidemic "black technologies", one of which is currently the world's smallest and most accurate wearable temperature measurement device "armpit band-aid" from Shandong Medical and Health Technology Co., Ltd. located in Tai'an. R & D team.

The "thermometer" has a chip sensor the size of a grain of sand. Those who need to measure the temperature only need to attach the device to the skin under the armpit to achieve automatic measurement and automatic reporting. Once abnormal body temperature is found, the remote detection personnel will issue an early warning, and the temperature measurer can also use the mobile App. Measurement results are available anytime after association. The temperature measurement accuracy of the "armpit bandage" is extremely high, reaching 0.05°C, and the detection accuracy of similar body temperature patches in the United States is 0.1°C-0.2°C. Moreover, the "armpit band-aid" has extremely low power consumption and can be used for 10 days on a single charge. At present, the upgraded version of the multi-sign sensing device of the "armpit band-aid", combined with the big data early warning platform, can realize 7 monitoring and early warning of body temperature, heart rate, respiration rate, blood oxygen, exercise, blood pressure and sleep. If any indicator of the staff wearing the device is abnormal, the system will automatically alarm.

Removal Team Set

On February 12 and 13, the Zhangjiakou competition area of the Beijing Winter Olympics fell continuously. The Genting Stadium waste removal and security team dispatched nearly 200 waste removal service workers to carry out ice shoveling, snow removal and other tasks to ensure smooth roads and other waste removal tasks. Done successfully.

It is reported that the clothing of these staff is provided by Coca-Cola China. The jacket design draws on the detachable function of outdoor jackets, and is equipped with detachable cold-proof jackets and trousers to meet the needs of operations under great temperature differences. The jacket fabric uses RPET material (Beverage bottle recycled material), with good waterproof and antifouling effect.

Warm flakes

The warm "inner core" in the uniforms of the Beijing Winter Olympics and the Winter Paralympic Games and the cold-proof clothing of the security police is manufactured by Jiangsu Kangda Nonwoven Co., Ltd. The special thermal insulation material for the Beijing Winter Olympics uniforms developed this time - multi-dimensional thermal storage and thermal insulation flakes, 70% of which use a variety of functional polyester staple fibers from Sinopec Yizheng Chemical Fiber Co., Ltd., and 30% of Hengtian China Fiber Spinning Chemical It is produced by mixing functional nylon staple fibers jointly developed by Wuxi Co., Ltd. and Shanghai Antu Flame Retardant Fiber Co., Ltd. These multifunctional staple fibers can absorb and convert light energy and thermal energy of the human body and can achieve long-term heat storage. At the same time, the functional staple fibers are light, soft, resilient, and hygroscopic, which improves the comfort of the thermal flakes. sex.
