Abstract

Woven fabric structures have, on account of the manufacturing process, a characteristic waviness of the fabric threads are not uniform, weft and warp threads are curved depending on the weave type, weaving process, coating process and the tension rate. If tension forces are applied to such a fabric, then displacements of the fabric structure take place as a result of the alteration of the thread curvature, which are described as constructional strain. This phoneme is fitted better by a viscoelastic material. These property one of results of ranking of textile subject for end use. The relationship between applied stress and resultant strain contains a timedependent element parameter. In stress-strain behavior of textile material we can get various, parameters like initial modules, yield stress, yield strain, region beyond the yield point, tests relevant to this phoneme, all pervious behaviors of textile material discussed in this paper. The main objectifies of this brief to clearly understand the fundamentals of deformation of textile martials under representation of stress to clarify the terminology the fabric structure and strain variation during deformation. We cannot confirm or deny the existence of a uniform stress behavior for one type of textile material, but this data is assumed to be categorized for each experiment separately. Exploration and examination in textile stress behavior require more and more experiment's trails and proof.
