Chemical Composition of Natural Fibers Using the Measured True Density. Case Study: Ichu Fibers

ABSTRACT

On any industry where the natural fibers are used, chemical composition of the fibers is an important parameter to determine, since it allows to predict the product quality. On the other hand, TAPPI standard developed a well described methodology to determine the chemical composition; however, their methodology is time and resource consuming, and furthermore it requires well trained specialist. An alternative to determine the chemical composition is to use the true density, since the density of the fiber constituents are different. In this study, we present a clear relation between the true density and the three major constituents (cellulose, lignin and extractives) with the fitting parameter R > 90%, for the Stipa obtusa base fibers.

摘要

在使用天然纤维的任何行业中, 纤维的化学成分都是一个重要的参数, 因为它可以预测产品质量. 另一方面, TAPPI标准制定了一套完善的方法来确定化学成分; 然而, 他们的方法费时费力, 而且需要训练有素的专家. 另一种测定化学成分的方法是使用真实密度, 因为纤维成分的密度不同. 在本研究中, 我们提出了针茅基纤维的真实密度与三种主要成分 (纤维素, 木质素和抽提物) 之间的明确关系, 拟合参数R>90%.
