Abstract:

The aim of this paper is to show, using comparative analysis, all the differences, as well as existing advantages and disadvantages of two different sizing procedures. Materials used in the implementation of this extensive research are ring-spun cotton yarns, sized with PVA size. Test parameters of the yarn were analyzed, subjected to statistical analysis and compared. All the knowledge obtained is supported by a detailed analysis of microscopic cross-sectional images of unsized yarns and those sized with both processes, where differences between the two sizing processes in the distribution of size pick-up on the yarn are distinctly observable. The whole research, which is based on proving the technological justification and optimisation of pre-wet sizing, lead to the conclusion that it is a really exceptional technological process, which greatly contributes to large savings of sizing agents, water, energy and environmental protection, without any consequences for the quality of sized yarn.
