Abstract  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 .

几种笋壳的化学成分及其纤维素特征

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.
