First, I need to reduce clothing purchases. Second, the delicates cycle is actually worse than the regular cycles. Third, the microplastics are being shed even in the air, so not washing them as often helps, but still does not stop the air pollution they give off. Lastly, even 'natural' fibers may be treated with toxic chemicals that shed in the air and water and are just as harmful. Apparently, up to 30% of chemicals by weight are allowed on natural fibers. These chemicals can be fire retardants, stain retardants and fiber life extenders.
