Abstract
The aim of this work is a development of new products, i.e. cotton like woven fabrics with increased extensibility, using textured multifilament polybutylene terephthalate (PBT) yarn in a weft direction and a proper finishing procedure. For the research purpose, a set of referential samples of woven fabrics containing PBT was made. The fabrics differed in the sequences of cotton and PBT yarns in the weft direction. In some samples a doubled PBT yarn is inserted in as one weft, simulating double linear density. The influence of the textured PBT yarn quantity on the elastic properties of cotton/PBT woven fabrics, developed after the treatment in boiling water for 30 minutes, was studied. The contraction in warp and weft directions that affect warp and weft density, thickness, mass per unit area and tensile properties were measured using standardised methods. The quantity of PBT mainly influenced the elasticity in weft direction. The highest elasticity correlated well with the highest quantity of PBT. Furthermore, a minimum portion of PBT effectively improved the tensile properties of treated fabrics in both directions, this being important in such cases, as the fabrics mostly keep their cotton character. The use of PBT and proper finishing procedure for developing the required increased elastic properties of woven fabrics for any purposes could be of significant advantage in the terms of price (compared to Lycra®) and production time (preparation for weaving and speed of weaving).
