FABRIC DEFORMATION BEHAVIOUR MODELLING IN VARIOUS ZONES OF A LOOM
This article proposes a method for calculating the deformation properties of the fabric in various zones of the loom - the “doffer-breast beam” zone and the “fabric edge - breast” zone. Nonlinear bending theory for determination of structure parameters for fabric on the loom underlies the calculations. The resulting models can be used as part of a mathematical model to calculate the single-layer fabrics forming process parameters - impact force, force of tension of warp thread and fabric at the moment of impact. The model of relative deformation change in fabric depending on load is obtained. This is cleared by numerical techniques. What affects computational accuracy, is the number of intervals the modelled lot is divided into. Justification of number of lots to provide the accuracy of calculations sufficient in practice has been adduced in the article.
