Relationship between Fiber Fineness and Diameter of Three Bast Fibers

ABSTRACT

Natural plant fibers are outstanding materials in textile industry. The fiber fineness, length and strength are three of the most important indexes to evaluate the fiber quality. Fiber fineness refers to the thickness of the fiber, which is usually expressed by the mass per unit length. The relationship between fiber fineness and fiber diameter is very important for deeper understanding of a new fiber. In this study, three different natural fibers were collected to measure the fiber fineness, diameter, and density. Furthermore, SEM was conducted to detect the fiber cross section, and the correlation equations were constructed between the fiber fineness and diameter. Results showed that vibration method could generate a lower fiber fineness value; all the correlation equations had high accuracy to predict fiber fineness with different diameters, and most of the prediction errors were lower than 10%. In the final equations, the coefficients were 0.825, 0.69, 0.975 of apocynum, ramie, and kenaf fiber, respectively.

摘要

天然植物纤维是纺织工业的重要原料。纤维细度、长度和强度是评价纤维质量的三个重要指标。纤维细度与纤维的直径相关，通常用单位长度的质量来表示。纤维细度与纤维直径的关系对于深入了解一种新型纤维具有重要意义。在这项研究中，收集了三种不同的天然纤维来测量纤维的细度、直径和密度。利用扫描电镜（SEM）对纤维截面进行了检测，建立了纤维细度与直径的相关方程。结果表明，振动法可以得到较低的纤维细度值，所有的相关方程对不同直径的纤维细度都有较高的预测精度，大部分预测误差小于10%。在最终方程中，罗布麻、苎麻和红麻纤维的相关系数分别为0.825、0.69和0.975。
