繊維集合体のみかけの摩擦成分を圧縮特性から予測する理論について

抄録

This paper describes a theory for expecting apparent friction (F_B) including in friction (F) between fiber assembly (yarns and woven fabrics) and a cylindrical steel rod (0.05 cm diameter and 0.5 cm length) from their compressional characteristics value which is measured by the same rod. F_B is considered to result from the internal loss energy in fiber assembly under deformation with friction.
F_B is expressed as follows :
F_B=k√Z/0.413 (dW_L/dZ),
where Z is the compressional distance at load P and W_L is the loss energy measured from one compressional-recovery test. In yarns, F_B calculated agrees with the observed value for k=1. But, as a whole, the relation may not be applicable for fabrics, although the observed value is nearly equal to the calculated for k=1.5.
