Research of Degumming Process, Microstructure and Properties of Mulberry Fiber

More and more novel nature fibers are used in textiles. The natural fibers include banana fiber, pineapple fiber and bamboo fiber etc. In this paper, as a kind of novel natural fiber, mulberry fiber is studied. The chemical component of mulberry bast is tested and analyzed. Meanwhile, the degumming method and process of mulberry bast are studied. Chemical degumming experiments to investigate the influence of alkali concentration, alkali boiling time and sodium phosphate tribasic ratio to material are conducted. Consequently, optimum parameters are obtained. The crystallinity of mulberry fiber is tested by using X-ray line, and the photos of scanning electron microscope （SEM） are observed. Testing results of the fiber properties （e. g. fineness, tenacity, length and elongation） show that mulberry fiber can be spun blend with cotton.     

并条机主牵伸区牵伸力在线测量系统的研制

牵伸力的大小及稳定是影响牵伸效果的重要因素,反映了牵伸过程的难易程度及对纤维运动的控制.一个合理、准确的牵伸力测量装置是研究牵伸力的前提条件,针对现有并条机多带有上托式压力棒牵伸装置的结构特点,自行研制出一套在线测量牵伸力系统.该系统主要由称重传感器、数字显示仪、上托式压力棒和电脑终端等部分构成.经变换牵伸倍数的试验,结果表明本系统的测试结果更为稳定、更接近实际.
