Evaluation of microfiber release from jeans: the impact of different washing conditions
Summary
Researchers quantified microfiber release from three denim jeans during domestic washing, finding that wash temperature, detergent type, and number of wash cycles all affect the quantity of synthetic microfibers shed into wastewater.
Microplastic particles are a burgeoning population crisis in the marine environment. This research examines the emission of microfibers from three different jeans (garments) during domestic washing. The jeans types, washing temperature, washing duration, spin speed, detergent types, and addition of conditioner are the main factors for this research work. The average length and diameter of the microfibers for the 100% PET jeans (jeans-P) has 7800 ± 4000 μm and 11.9±3.2 μm and for polyester/cotton jeans (jeans-PB) has 4900 ± 2200 μm 17.4±4.8 μm, respectively. The maximum microfiber released was observed in the rigorous washing treatment (90 min, 60°C, 1400 rpm, powder detergent with the presence of conditioner). The surmised number of microfibers discharged from the 1 kg wash load of jeans-P was calculated within the extent of 2300000-4900000 microfibers, and it is varied by the washing treatments.
