This process involves pre treating waste textiles, classifying, disinfecting, tearing and breaking them, and pre processing them into regenerated fibers. The regenerated fibers are made into needle punched felt through opening and mixing, combing, netting, and needle punching. The regenerated fibers are then made into hot melt felt through opening and mixing, air flow netting, and hot melt bonding. The needle punched felt and hot melt felt are bonded together to prepare the regenerated fiber felt.The equipment used in the process of preparing recycled felt from waste fabrics mainly relies on electricity as the energy source, and production requires domestic water input. The waste pollutants generated during the preparation process are mainly dust, which is captured by a bag filter system. The solid waste produced mainly includes waste scraps, scrap metals, waste packaging, slag, etc. The wastewater generated by the project is mainly domestic wastewater, and the main components of the waste gas pollutants are solid particles such as dust and smoke.This dataset is applicable to the process of producing recycled felt from waste fabrics.
