Uniforms in the Expo Park
There are many highlights and attractions in the Expo, but what catches your eye and impresses your mind are the uniforms in and outside the venues, except for the bizarre and magnificent buildings on the periphery of the venues. Whether it is Expo officials, service personnel, volunteers, security guards or news media workers, they all wear different styles and specially customized clothes. These garments reflect the scientific and technological progress of China's textile and garment, both in design and function.
361-degree (China) Co., Ltd. provided 13, sets of equipment for the city volunteers of the Shanghai World Expo, among which the fabric of the clothing is specially treated, which is windproof, waterproof, warm, light and comfortable, and has strong outdoor functionality. According to the working characteristics of media reporters, Shanghai Metersbonwe Bang Wei Clothing Co., Ltd. specially designed a breathable and rainproof garment with large reflective strips. Xtep provided 8, sets of special clothes for volunteers in the Expo Park, and used natural and environmentally-friendly cotton materials in fabric selection; In the production process, the knitting technology with high-tech content is used to meet the requirements of both aesthetics and comfort of clothing. Because the World Expo spanned many seasons and the weather was changeable, the clothing of volunteers was specially designed: the length of sleeves could be changed at will, and the length of trousers could be "stretched" freely. In addition, the functions of rain, wind and cold protection of clothing have also been strengthened. The fabric of volunteer clothing also has the effect of instantaneous cooling. When the fabric touches the skin, it can produce an instantaneous cooling sensation of 1~2℃. If it is exposed to sunlight for a long time, the temperature difference of cooling sensation can reach 3~5℃.
Textile science and technology display their talents
The brilliance of industrial textiles can be seen everywhere in the landmark buildings of the Expo site, which embodies the scientific and technological achievements of industrial textiles. Around the World Expo Center, the world's largest continuous cable membrane structure, which is spliced by white membrane cloth connecting the China National Pavilion and the theme pavilion, is like handfuls of huge umbrellas to shelter visitors from the wind and rain, and also like patches of white clouds, forming a unique and beautiful landscape in the park. Generally, this kind of membrane structure material is based on high-strength polyester industrial fiber or glass fiber woven fabric, and both sides are compounded or coated with high polymer materials such as polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF) or polytetrafluoroethylene (PTFE). It is the first choice for large-space span buildings in the world today, and has the advantages of light structure, large span, quick installation, low cost, fire prevention and flame retardant and high safety. According to the reporter's understanding, because there is still a certain gap between the membrane materials produced in China and those produced abroad, most of the membrane structure materials in the Expo site are imported.
The carbon fiber bicycle in the oil museum only weighs about 4 kilograms. Carbon fiber has high strength and light weight, its specific gravity is less than a quarter of that of steel, but its tensile strength is 7-9 times that of steel. It is a new material for military and civilian use, and is mainly used in aviation, chemical industry and medicine.
In the Petroleum Pavilion located in Zone D of the World Expo, the materials of the exterior wall, the clothing, chemical fiber products and industrial textiles in the pavilion all gather the achievements of textile science and technology. In the "Wear Oil" exhibition area, the wax figures wearing various costumes at the entrance are lifelike, and the process of changing oil into clothing is continuously played on the big screen. The exhibition hall of petroleum and chemical fiber products displays the in-cabin spacesuit and special police uniform independently developed by China. Those spacesuits and helmets with the characteristics of heat insulation, earthquake prevention, radiation protection, shock absorption and light weight represent the highest scientific and technological level of textile and clothing in China; Special police uniforms are made of non-toxic, flame-retardant and breathable fabrics, which have the functions of high temperature resistance, impact resistance and bulletproof; The parachute of the return cabin is made of high strength and high modulus textile materials; Chemical fiber products such as carbon fiber bicycles have gradually entered people's lives ... These objects vividly show the course of China becoming a world textile power through decades of efforts.
Soybean fiber has entered the World Expo as the greenest and most environmentally friendly material in the world. The low-carbon environmental protection materials used in the Austrian National Pavilion and China Sichuan Pavilion are all from soybean fiber materials provided by Yuanxiu Baby Clothing Company.
The high-tech material "optical fiber cloth" developed by Taiwan Province Guandehong Science and Technology Co., Ltd., which is a high-tech product combining textile and photoelectric technology, once made its mark at the Spring Festival Gala, and made its debut at the World Expo this time. It is understood that this kind of fabric is made of superfine optical fiber, which is woven into a flat fabric by using foreign fiber yarns through traditional textile technology, and can emit light as a whole after being electrified. It is no different from ordinary fabrics during the day, but it can emit colorful light at night or in the dark.

Continuation of Reality
In the SAIC-GM Pavilion, two "treasures of the town pavilion" independently developed by SAIC were displayed: the concept car of negative emission "Leaf" and the concept car of electric networking "EN-V".
As the name suggests, the big leaf on the roof of a car is a wonderful photoelectric converter, which simulates the photosynthesis of leaves in nature and converts solar energy into electric energy. No matter whether it is cloudy or rainy, the "leaf" can absorb solar energy and realize the maximum utilization of energy. "EN-V" realizes the compatibility of manual driving and automatic driving. It can automatically choose the best driving route through the analysis of real-time traffic information, thus alleviating traffic jams. It can also perceive the surrounding environment and make rapid adjustments when encountering obstacles or changing driving conditions. This information exchange with other vehicles and road infrastructure can greatly reduce the occurrence of traffic accidents.
Smart Grid: Smart "Electric Housekeeper"
Dream Show
In the State Grid Pavilion, there is a beautiful blueprint for the future smart grid-
Just press a button to control the switches of household appliances such as air conditioners and microwave ovens; Every household can become a "trading station" for electric energy, which can generate electricity while using electricity. If the home is equipped with wind and solar power generation equipment, it can be "uploaded" to the public power grid after it is used up. Users can see the real-time electricity consumption through smart meters, including the electricity consumption of air conditioners, air purifiers and other electrical appliances, and make timely adjustments ...
In a word, smart grid is like a smart "electricity housekeeper", which efficiently manages everything related to electricity for you.
Continuation of Reality
There is a smart grid demonstration zone in Yuefuting Community, Eshan Road, Pudong, Shanghai. At present, more than 1 households have enjoyed the convenience brought by smart grid. Only one terminal is needed to control all home appliances, and remote control is not difficult. Through the smart meter, not only can the household electricity consumption at different times of the day and the electricity consumption of each appliance be clear at a glance, but also it can help users to use electricity more economically according to the different electricity prices during peak and valley periods.
According to the person in charge of State Grid, the development of smart grid in China will be divided into three stages: 29-21 is the planning pilot stage; From 211 to 215, it is a comprehensive construction stage, initially forming a smart grid operation control and interactive service system; From 216 to 22, it will lead the upgrading stage, and a unified and strong smart grid will be built in an all-round way.
