From closet to contaminant to control: Unveiling microplastic sources in household textiles and potential for environmental application
Degraded domestic textile fibers were chemically and thermally activated and tested for dye remediation, with ZnCl₂-activated polyurethane and polyester fibers showing the best removal efficiency (up to 87.7%) for anionic dyes, repurposing textile microplastic waste for environmental cleanup.
Textile Recycling’s Hidden Problem: Surface-Modified Fiber Fragments Emitted at Every Stage
Researchers investigated microplastic fiber release during chemical recycling of polyester-cotton blended textiles and found that the dye removal stage generated the highest fiber counts, averaging around 10,055 fibers per gram of textile waste. Alkaline hydrolysis reduced fiber emissions during the treatment stage by nearly 88% compared to acid hydrolysis. The study highlights that textile recycling processes, while essential for sustainability, can themselves be a significant source of microplastic fiber pollution.
