Effect of polyester fibre shrinkage on construction characteristics of polyester/wool woven fabrics

Abstract

This work aimed to study the effect of polyester fibres with different shrinkage on the structural characteristics (warp densities, weft densities and weight per square meter) of the various blend wool and polyester fabrics, after a normal clean finish. The main conclusions to be highlighted are: polyester fibres with 11% shrinkage give rise to higher weft densities and consequently fabrics with a higher weight per square meter compared to fabrics produced with polyester fibres with 4% shrinkage. In this context, and if for technical and/or commercial reasons, there is a need to change the type of polyester fibre, it is not enough to consider only the length, diameter, crimp and tenacity of the fibre, but also its shrinkage.
