Comparative assessment of wet and dry garment cleaning: Part 2. Performance, economic and regulatory assessment

摘要: Abstract An assessment of the environmental burdens and human health effects perchloroethylene-based dry cleaning aqueousbased wet was documented in first paper this two part series. This investigates key performance, economic regulatory issues that affect viability as an alternative to cleaning. In demonstration studies, over 60% test garments were successfully cleaned with a high level finished quality. The most significant performance issue garment shrinkage. Approximately 30% each studies experienced unacceptable shrinkage although no correlation between fabric or type found. Preliminary cost data from recent projects indicate can be competitive Higher labor water utility costs for are offset by higher agent equipment related purchase, control, disposition perchloroethylene addition, cleaners United States must meet regulations Clean Air Act, Resource Conservation Recovery Superfund Amendment Reauthorization Water Occupational Safety Health Act. certain states, also pay special taxes levied on usage perchloroethylene. It appears industry is not willing sacrifice perchloroethylene's superior avoid low risks associated well-maintained dry-to-dry equipment. Mixed mode facilities may provide interim strategy reduce gradually expand application technology.
