Abstract:

In order to understanding the morphological structure,physical and mechanical properties of fibers from rice straw,the morphology,chemical structure,crystallinity and orientation of fibers were tested by the scanning electron microscope,infrared spectra,X-ray diffraction.The length,linear density,moisture regain,breaking strength,breakage elongation and flexibility of rice-straw fibers were tested as well as. The experimental results indicated that,the lengthwise of the fiber has a large number of grooves and it’s specific surface area is large.The crystallinity and orientation of rice-straw fibers are high.The length of the single fiber is very short. The processing fibers is made with half degumming process. The linear density of processing fibers is relatively large and the softness of processing fibers is poor.The moisture absorption of fibers is good.
