你穿的摇粒绒,可能是塑料瓶变的

Group 1 - The core idea of the article is the transformation of plastic bottles into fleece fabric, highlighting the environmental benefits and innovative processes involved in this recycling method [1][7]. - Fleece and plastic bottles share a common raw material, PET (polyethylene terephthalate), but they are not equivalent; the processing methods and properties differ significantly [2][3]. - The recycling process involves four main steps: cleaning the plastic bottles, melting and purifying the material, modifying the molecular structure, and finally spinning the fibers into fleece fabric [4][5][6]. Group 2 - China can recycle 20 billion plastic bottles annually into fleece, which could wrap around the Earth 30 times, and the carbon footprint of this production process is reduced by 60% compared to traditional fabrics [7]. - Not all fleece is made from recycled plastic bottles; most polyester fibers still come from petroleum, and recycled options are not yet mainstream due to higher costs and limited raw materials [8]. - Major brands like Adidas and H&M plan to switch half of their clothing lines to recycled polyester, and consumers can identify these products by looking for labels indicating "recycled polyester" or "rPET" [8].
