AI Technical Summary
Washing machines discharge wastewater containing a significant amount of fiber fragments less than 3 mm in length and microplastics due to the inefficiency of mesh nets used in typical lint filters, leading to environmental pollution and accumulation in aquatic and animal bodies.
A filter comprising a first nonwoven fabric layer with a higher fiber density and a second nonwoven fabric layer with a lower fiber density, where only the peripheral portions of both layers are integrated, effectively capturing small and large particles while maintaining liquid permeability.
The filter efficiently captures small particles like fiber scraps and microplastics, preventing their release into the environment and maintaining filtration performance over time without clogging.
