摘  要：
为探索笋壳纤维的资源化利用途径,采用化学分析、扫描电镜、红外光谱、X-射线和热分析等方法研究其化学成分和结构特征.结果表明:1)笋壳纤维中纤维素、半纤维素含量丰富,分别为36%~40%和35%~46%,木质素仅占1%~8%;2)笋壳纤维呈圆柱形,有沟槽、脊、裂缝和螺旋扭曲;3)笋壳纤维属于典型的纤维素Ⅰ型,在红外光谱中,具有一般纤维素的特征吸收峰;4)经测定,笋壳纤维的结晶度为40%左右,与水稻秸秆纤维类似,但低于棉、麻纤维;5)在热重分析曲线中,笋壳纤维有2个失重阶,在190℃左右开始热分解,主失重温度约为310℃左右.初步研究结果表明笋壳纤维具有一定的开发潜力,可广泛应用于纺织、造纸、复合材料、精细化工等方面.

摘  要：
In order to broaden the utilization approach of bamboo shoot shells,advanced techniques such as scanning electron microscope(SEM),Fourier transform infrared(FT-IR),X-ray diffraction(XRD) and thermal gravimetric analysis(TGA) were employed to characterize the natural biofiber.The main results were as follows: 1) Fibers of bamboo shoot shells were mainly composed of 36%-40% cellulose and 35%-46% hemicellulose,while the content of lignin was only 1%-8%;2) the fiber of bamboo shoot shells was circular with obvious grooves observed by SEM;3) in the infrared spectrum,it had a general characteristic of cellulose absorption peaks;4)the fiber of bamboo shoot shells belonged to the typical cellulose type I,and the crystallinity was about 40%,which was similar with fiber from rice straw,but was much lower than cotton and hemp fibers;5) in the TGA curves,the fiber began to decompose at about 190 ℃,and the main mass loss temperature was about 310 ℃.The primary study indicate that bamboo shoot shells can be widely used in textile,pulp and paper,composite and various industrial processing,as a good source for natural cellulose fibers.
