有关聚酯纤维衣料，这些传说是真的吗？

Core Viewpoint - The article discusses the truth behind the claims that polyester fiber clothing is made from plastic bottles, confirming that a portion of polyester is indeed derived from recycled PET (polyethylene terephthalate) plastic bottles [2][3]. Group 1: Polyester Fiber Production - Polyester fiber, commonly used in clothing, is derived from the same petroleum-based raw material, PET [3]. - There are two main sources of polyester fabric: virgin polyester produced from petrochemical raw materials and recycled polyester (rPET) made from used plastic bottles [3]. - The technology for producing high-quality recycled polyester has been established for decades, with similar strength, durability, and feel compared to virgin polyester [3]. Group 2: Consumer Preferences - Many consumers prefer products made from recycled polyester as a way to support environmental initiatives [4]. Group 3: Static Electricity Concerns - The claim that wearing polyester clothing causes static electricity is not entirely accurate; static is primarily due to the physical and chemical properties of polyester fibers [5]. - Polyester fibers have low moisture absorption and high electrical resistance, leading to charge accumulation in dry conditions [5]. Group 4: Microplastics and Health - The assertion that wearing polyester can lead to microplastics entering the bloodstream is largely sensationalized; scientific consensus indicates a very low likelihood of this occurring during normal wear [6]. - Healthy skin acts as a barrier, effectively preventing microplastics from penetrating into the bloodstream [6]. Group 5: Environmental Impact - Concerns are raised about the long-term potential impact of polyester on water and soil, particularly when discarded polyester products contribute to microplastic pollution through degradation [7].
