This process involves the pretreatment of waste textiles, followed by classification, disinfection, tearing, and opening to produce regenerated fibers. The regenerated fibers are then processed into needle-punched nonwoven felt through opening, blending, carding, web laying, and needle punching. Alternatively, the fibers are formed into thermobonded nonwoven felt via opening, blending, air-laying, and heat bonding. Finally, the needle-punched and thermobonded felts are combined to produce regenerated fiber felt.
The equipment used in the production of nonwoven felt from waste textiles primarily operates on electrical energy and requires input of domestic water. The main waste emissions generated during the process are dust particles, which are captured by a baghouse dust collection system. The solid waste products mainly consist of waste scraps, waste metals, waste packaging materials, and furnace slag. The wastewater generated by the project is primarily domestic sewage, and the main components of the emitted air pollutants are solid particulates such as dust and soot.
This dataset is applicable to the process of producing recycled felt from waste textiles.
