Issues involved in drying and determining the porosity of yarn filaments are considered. A technique is proposed for the experimental determination of yarn filament porosity based on an analysis of their drying curves. An algorithm for the automated processing of the experimental results and subsequent determination of the apparent porosity of the yarn filaments is presented. The results of calculating the porosity of polyamide and viscose multifilaments are shown to be in good agreement with those predicted according to theory.

纱线长丝毛细孔结构实验研究方法的发展

考虑干燥和确定长丝孔隙率所涉及的问题。提出了一种通过分析其干燥曲线来测定纱线长丝孔隙率的技术。提出了一种用于自动处理实验结果并随后确定纱线长丝表观孔隙率的算法。结果表明，聚酰胺和粘胶复丝的孔隙率计算结果与根据理论预测的结果吻合良好。
