Uncontaminated textile waste, old clothing materials, inferior cotton and other garbage are recyclables;
Uncontaminated waste textiles, such as used clothes, ingredients, spinning, packaging, plastic products, etc., are also recyclables.
But from this we can feel that the amount of waste textiles is beyond our imagination. According to the "White Paper on the Progress of China's Waste Textile Recycling Technology" released recently, China's annual waste textiles can reach 20 million tons.
Under the guidance of relevant policies in recent years, China has initially formed an industrial chain for recycling, sorting, dismantling, and processing of used textiles. However, the recycling rate of waste textiles in China is still less than 20%.
According to the data of the Prospective Industry Research Institute, in the recycling of renewable resources, the recycling value of waste textiles increased significantly, and the proportion in 2017 increased by more than 50%. Therefore, how to achieve high-quality recycling of waste textiles is an important issue in the industry. This is also the original intention of the "2019 Waste Green Textiles High-value Utilization Green Industry Chain Innovation Forum" held in May 2019.
Experts at the meeting unanimously agreed that waste textiles are a category with a lack of back-end high-value utilization systems. It is urgent to research new technologies and new fields and break through the bottleneck of industrial back-end utilization.
In the realization of high-quality recycling of waste textiles, there have been some innovative practice cases in China. Professor Wu from East China University of Science and Technology has developed a fiber-plastic composite material prepared from waste textile fiber reinforced polyolefin modified materials.
According to Professor Wu, this composite material can be recycled many times and can be widely used in industries, agriculture, construction and life, providing a new way for recycling and recycling of waste fiber.
In addition, the intelligent functional textile composites innovation team of the School of Textile Science and Engineering of Xi'an Polytechnic University used waste denim and processed and processed it to make a material similar to the adhesive sheet. This material can be used as a thermal insulation material or a sound insulation material, and the new material produced by the technical treatment on this basis forms a "hard board" for making furniture, and replacing the wooden floor is not a problem.
Associate Professor Fan Wei, the team leader, said that smart wearable textiles with real-time monitoring functions such as heart rate, pulse and human motion status will be popular. Currently, he and his team have made some smart wearable textiles with piezoelectric fibers.
It is worth noting that innovation “textile” will increasingly integrate into every aspect of life. Some materials and clothing with special functions will be the focus of future research and development, such as no-wash, anti-bacterial deodorization, moisture absorption and quick drying.
The data show that China has accumulated more and more experience in the utilization of waste textile resources and can obtain more innovative clothing raw materials through the resource utilization of waste textiles, and further exploration is needed.
According to the industry's rough calculation, if China's waste textiles can be fully recycled, it is equivalent to saving 24 million tons of crude oil and nearly one-third of the cotton planting area per year, which can reduce carbon dioxide emissions by 80 million tons.
Especially in the exploration of promoting the high-quality recycling of waste textiles, there is no shortcut, only to go forward.
