摘　　要：采用棉秆皮上部与根部在碱脱胶前经硫酸溶液浸泡一定时间,研究脱胶前硫酸预处理对棉秆皮纤维长度、细度、可挠度、残胶率等的影响.实验结果表明,棉秆皮纤维在脱胶前经硫酸溶液处理可降低棉秆皮纤维的残胶率,减小纤维的细度,提高纤维的可挠度,且纤维的断裂强度、断裂伸长率无明显变化.综合考虑各项指标,硫酸溶液的浓度取30～50mL/L为宜.In this study,the upper parts and roots of the cotton-straw bark are immersed by the sulfuric acid solution for a certain period of time before the alkaline degumming.The influence of sulfuric acid pre-treatment on the length,fineness,pliability,residual gum content of nature cellulose fiber from cotton-straw bark are studied.The results show that the residual gum content,fineness are reduced and pliability is increased in the condition of sulphuric acid solution before the alkaline degumming and it has no apparent affect on breaking tenacity and elongation at break.Comprehensive consideration of the various indicators,the best concentration of the sulfuric acid is about 30~50mL/L.
