中性纤维素酶整理对丝光棉织物性能影响的研究

摘要

研究了中性纤维素酶整理丝光棉织物后对其性能的影响,通过试验分析了酶用量、pH、整理温度和时间对织物失重率、顶破强力、硬挺度及抗起毛起球性的影响,并确定最佳工艺条件:酶用量2.0％(omf),pH=7.5,整理温度50℃,整理时间55 min.在最佳工艺条件下整理的丝光棉织物,各方面性能有不同程度的改善,顶破强力控制在220 N以上.%The influences of neutral cellulase finishing on properties of mercerizing cotton fabrics were studied. The effects of the dosage of cellulase, pH, treating temperature and time on the weight loss rate, the bursting strength, the stiffness and the pilling resistance were investigated. The optimum process was determined: the dosage of cellulase was 2.0%(omf), the pH was 7.5, treated at 50 ℃ for 55 min. The various aspects of performance of the mercerizing cotton fabrics under optimum process were improved to some extent. The busting strength was controlled over 220 N.
