How to determine the fiber morphology of plant fiber raw materials?

Abstract: 本文讲述了植物纤维原料纤维形态测定的几种方法。主要包括:光学显微镜,通过显微镜观察纤维的长度、直径、壁厚以及形态特征如分支和表面结构;扫描电子显微镜(SEM),提供高放大倍数的表面形态和细节信息,如表面纹理和孔隙;透射电子显微镜(TEM),能观察纤维的内部结构,包括壁厚和中空部分;纤维素形态分析仪,一种专门用于纤维形态分析的仪器,可以测定纤维的长度、宽度、直径和角度等参数。通过这些方法的单独或组合使用,可以全面准确地获取植物纤维原料的形态信息。

The following methods can be used to determine the fiber morphology of plant fiber raw materials:

  • Optical Microscopy: A microscope is used to observe the shape and size of plant fibers. This method can be used to measure the length, diameter, wall thickness and other parameters of the fiber, and can observe the morphological characteristics of the fiber, such as shape, branching situation, surface structure and so on.

  • Scanning electron microscope (SEM): The surface morphology and structure of plant fibers can be observed using SEM, including surface texture, pores, etc. This method also allows for higher magnification and greater detail.

  • Transmission Electron Microscopy (TEM): The internal structure and details of plant fibers can be observed using TEM, including the thickness and shape of the fiber wall, fiber hollow and pores, etc.

  • Cellulose Morphology Analyzer: This is an instrument specially used to analyze the shape of plant fibers. It can measure the length, width, diameter, angle and other parameters of fibers, and can analyze the morphological characteristics and distribution of fibers.

The above methods can be used alone or in combination to obtain more comprehensive and accurate fiber morphology information of plant fiber raw materials.
