In this study, activated carbon was prepared from windmill palm sheath fiber (WPF) powder by KOH activation for full utilization of the bioresource. First, the optimal parameters of the activation technology, such as impregnation ratio, temperature, and time, were determined. The pyrolysis process and activation mechanism of KOH were investigated by thermogravimetric analysis (TGA). WPF powder-based...
α-amylase and pectinase showed good compatibility. A desizing ratio of 95.4 %, a pectin removal rate of 80.4 % and a capillary effect height of 7.1 cm for cotton fabrics treated with α-amylase and pectinase were obtained by a one-bath for bio-desizing and bio-scouring process under the condition of 90 °C for 30 min. After the treatment of the nonionic surfactant Peregal O at 100 °C for 20 min, these...
