摘要
为解决鸡毛纤维废弃量多、质量轻及难洗涤等问题,采用化学法和生物法对鸡毛纤维进行洗涤,通过正交试验,确定了化学法的最佳洗涤条件为无水乙醇体积浓度5 mL/L、pH值4.0～6.0、洗涤温度50℃、洗涤时间20 min、羽毛专用洗涤剂用量5%(owf)、浴比1∶30;生物法的最佳洗涤条件为双氧水体积浓度50 mL/L、pH值4.0～6.0、洗涤温度50℃、洗涤时间10 min、酸性蛋白酶用量3%(owf)、浴比1∶30。在此条件下,洗涤后的鸡毛纤维与未洗涤的鸡毛纤维进行比较,结果表明:洗净鸡毛纤维在白度、含脂率和含菌量上都有很大的差异,并且生物法的洗涤效果明显优于化学法,采用生物法洗涤后的鸡毛纤维白度可以达到70.3%,含脂率0.82%,含菌量2.6×103 cfu/g。
To resolve the problems that chicken feather fibers were large number of abandoned,light and difficult to wash,the methods of washing chicken feather fibers using chemical method and biological method were researched.The optimum process conditions were determined by the orthogonal experiments.The optimum process conditions of chemical method were ethanol 5 mL/L,pH value 4.0-6.0,the washing temperature 50 ℃,the washing time 20 min,dosage of feather special detergent 5%（owf） and liquor ratio 1∶30.The best process conditions of biological method were as follows： the hydrogen peroxide solution 50 mL/L,pH value 4.0-6.0,the washing temperature 50℃,the washing time 10min,the dosage of acid protease 3%（owf）and liquor ratio 1∶30.Under these conditions,chicken feather fibers were washed by chemical method and biological method,the effect of washed chicken feather fibers were compared with that of not washed.The result showed that the differences were very great in the whiteness,the grease content and the bacterial content of washed chicken feather fibers.The conclusion was that the effect of washed chicken feather fibers by biological method was superior to that of washed chicken feather fibers by chemical method.The whiteness was 70.3%,the grease content was 0.82% and the bacterial content was 2.6×103cfu/g by biological method.
