Abstract

In this paper, modeling of physical behavior of plain-woven fabrics under the condition of yarn pullout test is investigated.
An analytical model called “the oscillation model” is represented to estimate the required force of yarn pullout test for the
plain-woven fabrics. The main idea of this model is based on a combined approach of friction in interlacing points and
vibration of yarns during the pullout test. This oscillatory behavior is the outcome of the stick-slip motion, caused directly by
contact interactions in interlacing points. In this study, the oscillation model is investigated experimentally for five different
plain-woven fabrics. The model includes many physical parameters, which cannot be measured directly. These parameters
have been estimated using the force-balance model, which is another analytical model, for predicting the internal mechanical
parameters of the plain-woven fabrics in the same test. Experimental results showed that the oscillation model is a suitable
approach for anticipating the behavior of woven fabrics in the yarn pullout test.
