摘　　要：采用化学脱胶方法对玉米苞叶进行脱胶试验,旨在寻找一种较为适合玉米苞叶的脱胶新工艺,开发适合纺织应用的新纤维。利用正交设计试验方法,对玉米苞叶化学脱胶的煮炼助剂配方和煮炼工艺进行了优化,找出了最优工艺参数的组合。最优助剂工艺配方为:多聚磷酸钠浓度为3%,亚硫酸钠浓度为2%,硅酸钠浓度2%,草酸铵浓度2%。二次煮炼的最优工艺参数为:氢氧化钠浓度16g/L,煮炼温度80℃,煮炼时间40min。The chemical degumming method was used in corn husks degumming experiment so as to find a more suitable degumming process and to realize the development and utilization of corn husks fiber. The formula of scouring aux- iliaries and the scouring process of chemical degumming were optimized and the optimal combination of process parameters was found out by using orthogonal experimental method. Optimal formula of scouring auxiliaries： sodium polyphosphate 3 %, sodium sulfite 2 %, sodium silicate 2 %, ammonium oxalate 2 %. Optimal parameters of two scouring were NaOH 16g/ L, temperature 80℃, scouring time 40min.
