Expo clothing contains new technology T-shirt worn underground can be used as fertilizer

World Expo Volunteers' Uniforms

The staff of the French Pavilion (online French Pavilion) is also made of new fabrics

The uniform of the staff of the German Pavilion (online German Pavilion). Their uniforms are orange jackets and trousers, and their texture is very elegant.

Clothing, food, housing, and transportation are topics that people are most concerned about. What will we wear in the future and how to wear it? Let Shanghai Expo tell you.

This time, the textile and sci-tech community can present the achievements accumulated for many years before the world. The clothes displayed at the Shanghai World Expo are not limited to "conceptual" products. Some apparel fabrics containing advanced technology and special functions have been applied to the clothing of World Expo volunteers and staff of national exhibition halls. The concept of low carbon and circular economy may be practiced on a certain day. On you and my clothes.

Old clothes can be recycled

With the popularization of environmental awareness, the recycling of old clothes has become increasingly popular. However, most of the time, the old garments are only shredded and mop, quilts, and other low-grade products are used to recycle clothes.

The staff of the German Pavilion are different. Their uniforms are orange jackets and trousers, and a belt that can be hung on the waist. The full set of clothing is not surprising, but its texture is very particular about.

The T-shirts they wore buried in soil for 16 weeks could be completely degraded. The coat is even more magical and can be made into chemical fiber fabrics again through a series of techniques such as decolorization. Their shoes are made of natural rubber and softwood and can also be recycled.

A staff member of the Teijin Fiber Co., Ltd., which is responsible for producing the chemical fiber fabric, explained that the clothes were used ten times or eight times in a cycle and the feeling of wearing would not change.

This ecologically reinvented fabric, which can be recycled endlessly, was developed in 2002. The main technology is to recycle recycled Coke bottles, used clothes, and even waste newspapers through crushing, chemical reaction, and polymerization steps to make recycled polyester fibers. Fabric products. Clothing made from this fiber does not have the same feeling as other chemical fiber products; the difference is that the fiber can be decolored through technical means, while other fibers cannot. According to Japan Teijin Fiber Co., Ltd., this process can reduce the energy consumption and carbon emissions of garment production by 80%.

In the Japan Pavilion (online, Japan's industry hall), the clothes worn by service personnel also use this recyclable new fabric. After the Expo is over, these uniforms will be shipped back to Japan and processed and recycled through a recycling and recycling system.

The industry pointed out that there are two problems with this kind of ecological reentrant fabrics: First, because of the special technology, garment prices are generally about 1/3 higher than ordinary clothing, so its sales situation is not very good; second, because the fabric is still unable to Get rid of the characteristics of chemical fiber products, wear less comfortable cotton and linen products.

T-shirts can be completely degraded

The old German sportswear manufacturer TRIGEMA and EPEA International Environmental Research Co., Ltd. jointly developed a biodegradable T-shirt called TRIGEMA-Shirts. They are made of organic recyclable materials. In terms of wearing comfort, they are combined with ordinary cotton clothes. No difference. In addition, according to the staff of the German Pavilion, once the cotton T-shirt is exposed to the corresponding bacterial environment, it will be completely decomposed. Even clothing fuels and buttons will not cause environmental problems during the degradation process. The German Pavilion decided that after the Shanghai World Expo ended, these T-shirts would be buried under the German Pavilion to provide nourishment for the trees in the Expo Garden.

Although TRIGEMA-Shirts can be completely degraded when buried in soil, its stability is not bad and it does not cause embarrassing conditions such as fading during wear or washing. And its cost is not expensive, the cheapest one as long as 18 marks, about 76 yuan, the most expensive as long as 300 yuan, and ordinary brand T-shirts.

Domestic companies are also developing a large number of new “green fibers”, such as corn fiber made from corn ear shells, which are also easily biodegradable. About 3 pounds of corn ear shells can be used to make a T-shirt.

In addition, there is a soft silk fiber with a degradable protein, which is hot and breathable and keeps the skin in the most comfortable environment.

Clothes become close to the air conditioning

Rain-proof, wind-proof, anti-fouling, moisture-absorbing, breathable, anti-ultraviolet, fire-retardant, quick-drying. The green or blue clothing worn by the Expo's volunteers has the above functions. This fabric also has the effect of instantaneous cooling. When the fabric contacts the skin, it can produce a cool sensation that lowers the temperature by 1-2°C. If the fabric is exposed to sunlight for a long time, the resulting temperature difference can reach 3-5°C.

This cool fabric, called Flycool, also has the effects of moisture absorption and UV protection. The moisture regain of this cool fiber and the heat diffusion rate of the fiber are better than those of ordinary fiber, and there are various kinds of composite natural minerals, jade, etc. The clothing wearing this kind of fabric can increase the air conditioning by 1°C. According to statistics, Save 5% to 6% of the electricity bill, and reduce the amount of carbon emissions by approximately 0.62kg.

[Future trend]

Smart clothing:

It can be seen at the World Expo intelligence fire fighting suit. This set of intelligent fire fighting service with GPS positioning, vital signs detection and other functions adds a lot of intelligent design in addition to the functions of fire prevention, heat insulation and high temperature resistance.

For example, sensors can be installed on smart clothes to monitor the human heart rate, blood pressure, body temperature and other vital parameters. This enables real-time monitoring of human physiological signals and provides firefighters with emergency services.

In addition, smart protective clothing also has GPS positioning function. Through signal tracking, the monitoring command center can quickly and accurately determine the real-time position of firefighters, and then make effective command judgments and guide firefighters to follow an accurate route.

Buy clothes without "test":

In the short video of the SAIC-GM Pavilion that looks forward to the future of life, the shopper can press buttons before the digital fitting system to know the effect of clothes of different styles and colors on their own body type. This digital fitting system has already begun trials by many companies, which indicates that in the near future, each beauty-conscious woman can use this "magic mirror" to complete the fitting. What's even more interesting is that we can also use mobile phones to order satisfactory garments when we are driving, or to select the dresses to be worn at the dinner in the simulation closet... everything is like a science fiction novel, but it's also away from us. Not far away.
