The effect of a fabric softener treatment on the properties of the crossing torque–intersecting angle behavior of yarns and the transverse compression properties of single and crossing yarns, which are related to the shear properties of a fabric, is investigated. The crossing torque required to change the intersecting angle between two yarns, the hysteresis in the crossing torque–intersecting angle curve (i.e., crossing torque hysteresis), and the compression properties of cotton yarns after water treatment with and without softener were measured. To measure those properties, the drying condition was varied after the treatment to comprise crossed yarns with an applied load and parallel yarns in a bundled state. The average crossing torque value of the sample with a softener treatment was less than that with a water treatment for yarns from a bundle. For yarns dried while crossed, the average crossing torque value of the sample with a softener treatment was somewhat less than that with a water treatment. For both drying conditions, the average crossing torque hysteresis value decreased after a softener treatment. The compressional resilience value of the sample with a softener treatment was greater (bouncier) than that with a water treatment for yarns dried while crossed. The results suggest that the softener treatment reduces the crossing torque and increases the compressional resilience of yarns. This is due to the reduction of hydrogen bonding between surface fibers via the softener. The softener treatment also decreased the crossing torque hysteresis, corresponding to decreased friction between fibers.

研究了织物柔软剂处理对纱线的交叉扭矩-相交角特性以及单根和交叉纱线的横向压缩特性的影响，这些特性与织物的剪切特性有关。测量了改变两条纱线之间的相交角所需的相交扭矩，相交扭矩-相交角曲线中的磁滞（即相交扭矩磁滞），以及经过水处理和不经过软化剂处理的棉纱的压缩性能。为了测量这些性能，在处理后改变干燥条件，以包括施加负荷的交叉纱线和成束状态的平行纱线。对于来自束的纱线，经过软化处理的样品的平均交叉扭矩值小于经过水处理的样品的平均交叉扭矩值。对于在交叉时干燥的纱线，采用软化剂处理的样品的平均交叉扭矩值略小于经水处理的样品。对于两种干燥条件，在软化剂处理后，平均横向扭矩滞后值均降低。对于经交叉干燥的纱线，使用软化剂处理的样品的压缩回弹性值（弹性）大于水处理的样品。结果表明，软化剂处理降低了交叉扭矩并增加了纱线的压缩回弹力。这是由于通过软化剂减少了表面纤维之间的氢键。软化剂处理还降低了交叉扭矩的磁滞，
