Abstract:
In order to improve the moisture absorption and quick-drying properties of recycled polyester fabrics, 20,25 and 30g/L NaOH solution and a small amount of cationic surfactant 1227 were used to treat recycled polyester fabrics by alkali reduction process. The reduction rate and all indicators for the characterization of moisture absorption and quick-drying properties of treated and untreated fabrics were tested. The results showed that reduction rate is low when using 20g/L NaOH solution in the alkali reduction process. The physical properties of fabrics have little changed. For treated fabrics, the dripping diffusion time significantly reduced, and water absorption and wicking height of fabrics have substantial increased. The evaporation rate and water vapor permeability in unit time become increased obviously. The recycled polyester fabric’s moisture absorption and quick-drying properties have improved significantly by alkali reweighting process, and the treated fabrics meet technical requirements of the moisture wicking products.
Key words: recycled polyester, alkali reduction process, moistuer absorption, quick-drying
