摘要

Cotton stalk bark fibers (CSBF) were prepared using combined steam explosion and laccase treatment (explosion-laccase). CSBF have been applied to reinforce thermoplastic composites, but were difficult to be spun into yarns due to their inferior fineness and high stiffness. In order to improve the fineness and flexibility with a green method, explosion-laccase treatment was used to separate bark of cotton stalks. The results indicated that steam explosion at 1.7 MPa for 3 min effectively facilitated laccase penetration into the lignocellulose complex to enhance delignification without negative effects on activity of laccase. Compared with CSBF after explosion, CSBF after explosion-laccase had better fineness (31 dtex), higher aspect ratio (1110), higher tensile strength (2.81 cN/dtex), higher flexibility (321 twist/(m-dtex)), and better thermal stability, which meets the requirement of textile fibers. CSBF had higher water retention (127%) and moisture regain (10.3%) than cotton. Explosion-laccase is an effective and eco-friendly method of preparing CSBF for textiles.
