Energy Saving And Emission Reduction: Cotton Clothing Is Well Deserved.

Wearing cotton clothes is not only breathable and skin friendly, but also reduces CO2 emissions. Yesterday, "climate change and Low carbon textiles "High-level forum" was held in Shanghai, and more than ten academicians and experts from all over the country have tracked various textiles. carbon footprint "Compared with all kinds of chemical fiber fabrics, cotton clothing is Conserve energy,reduce emissions Experts, especially organic cotton fabrics, can reduce CO2 emissions by about 70%.

　 Cotton and linen fabrics are more environmentally friendly.

You can see that a cotton white long sleeved shirt, weighing more than 200 grams, from cotton cultivation, textile manufacturing, to transport, distribution, consumption, exhaust treatment and other life cycle carbon emissions, about 10.75 kilograms, is 50 times the weight of the shirt itself. Zhou Xiang, a member of the Chinese Academy of engineering and professor of Donghua University, pointed out that in the international and domestic dynamics of reducing greenhouse gas emissions in the textile industry, it is estimated that around 60 billion kilograms of fabric is produced each year, with an estimated consumption of 1 trillion kilowatt hours of electricity and up to 9 trillion liters of water. The entire textile industry is one of the largest greenhouse gas emissions industries on the planet.

However, the amount of CO2 emitted from producing different fabrics is different. For example, the production of 1 tons of synthesis fibre The CO2 emission is much more than that of producing natural fiber cotton or hemp. The CO2 emissions of acrylic and nylon clothing are more during the whole production process. In the production process of natural fiber, especially organic cotton, CO2 emission is relatively small. Data show that in the United States, organic carbon emissions per ton of organic cotton is 60% less than that of traditional cotton. If organic cotton produced with renewable energy can reduce 90% of CO2.

The potential to reduce carbon emissions during laundry washing is also great. For example, if you wash clothes with a washing machine, if the water temperature is 30 degrees, it will be less than 100 grams CO2 at 40 degrees centigrade.

　　 Straw fiber Ready-made garments

In order to reduce the overall carbon emissions of the textile industry, in addition to producing more cotton and linen fabrics, the proportion of chemical fiber fabrics should be greatly reduced. At present, scientists in various countries are actively studying biomass polyester fiber. Biomass fibers are mainly derived from plants, crops, agricultural wastes and by-products. For example, corn or other grain starch is converted into sugar after fermentation, then lactic acid bacteria is made into lactic acid, then melted and melted after polymerization, and finally made into corn fiber bedding, and can also be made. polylactic acid Fiber automotive interior trim.

The annual burning of farmland straw in the suburbs of Shanghai is also expected to become a source of biomass for all kinds of clothing materials. Jiang Shicheng, academician of the Chinese Academy of engineering, told reporters that in 5 years, the key technology of straw fiber production in China will be a breakthrough. In another 10 years or so, straw fiber products are expected to enter the industry and eventually decorate the lives of ordinary people.
