Description
This process involves preprocessing waste textile materials through methods such as dismantling, crushing, and drying, followed by sending them to a depolymerization unit to recover DMT. The recovered material then undergoes polymerization and pelletization to produce PET chips, which are further processed into regenerated filament.
Equipment used in the process of converting waste chemical fiber products into regenerated filament primarily operates on electricity. The main waste emissions generated during the process are dust, which is captured using a baghouse dust collection system. The solid waste generated from production mainly includes waste buttons, oligomer residues, molten filter residues, sludge, waste chips, and furnace slag. The wastewater generated by the project is primarily domestic sewage, while the main air pollutants emitted are SO2, NOx, etc. Dust and solid particulates are generated during the pretreatment, polymerization reaction, and spinning stages.
This dataset is applicable to the process of producing regenerated filament from waste chemical fibers.
Activity Description
This dataset represents the process of preparing recycled silk from waste textile raw materials through pretreatment, DMT recovery reaction, polymerization reaction, and subsequent pelletizing and spinning. It includes the consumption of energy and materials used in the production process, the generation of solid waste, and the emissions of wastewater and exhaust gases.
Process Description
Waste textile raw materials are cut into PET chips after pretreatment and polymerization reaction, and then regenerative silk is produced through spinning process
