High speeds of modern weaving machines set high demands for quality of applied yarns. While warp yarns are exposed to cyclic loading with abrasion, the weft yarns are exposed to impulsive loading with very high accelerations. The yarn should have such properties to stand the above loading and to assure good appearance of the fabric.

In order to carry out the activities of the research work, as well as to apply the achieved results to industrial practice, six different fabrics which properties, constructional parameters and production processes were researched in the project, were selected form the regular production of MTT-Fabric Factory Melje, Maribor. The selection criteria included the share as well as quality requirements of a certain fabric considering the whole production. Those fabrics, and consequently yarns and fibres, presented at that time a great share of production, and therefore also a potential for quality optimisation and reduction of material costs. Furthermore, the production of some of the above fabrics was sometimes denoted by poor quality. All the fabrics were made from 100% cotton fibres.
