Abstract
In order to clarify the frictional properties of fiber assemblies such as yarns and fabrics, the friction between a woven fabric and a rigid body is analyzed.
The results are as follows : The coefficient of friction μ can be devided into two components, μA and μB. μA is the component of friction between a fiber surface and a surface of a rigid body.μB is the component which comes from the other causes. The assumption is made that μB is related with loss energy caused.by the inter-fiber frictions during the compressional deformation when the fiber assembly is subjected to rubbing. [μB], theoretically calculated value of μB from the loss energy measured from the lateral compression test of a fabric, is compared with the experimentally measured value of μB. It has been concluded that values of [μB] are highly correlated with those of μB . However μB is about 25 times larger than [μB].
It is pointed out that the deformation of the fiber assemblies located near a front edge of the contactor is important for inducing the loss energy which causes μB, and that the inter-fiber friction mechanism at this part is different from the mechanism in the case when the fiber assembly is compressed by a plate.
