Supercritical CO₂ Extraction Pretreatment for Polyester/Nylon Microfiber Towel

Abstract:

A new degreasing pretreatment technology for quick-drying towels has been developed to solve the environmental pollution caused by a large amount of waste gas during the degreasing process. The optimal deoiling rate of oil extracted from the microfiber surface in supercritical CO₂ fluid is 95.45% when the temperature is 100°C, the pressure is 14 MPa, the time is 60 min, and the CO₂ flow rate is 30 g/min. The implications of various treatment temperatures and times on the effectiveness of oil agent removal are addressed.
