Influence of Thermo-Setting on the Quality of Air-Jet Textured Threads

Abstract

Air-jet texturing is one of the most perspective methods for manufacture of threads in order to obtain sewing threads of high quality and with excellent mechanical features. The goal of research is to analyse the dependence of qualities of polyester air-jet textured threads on thermo-setting. These threads designed for sewing various outfit were manufactured by the Department of Textile Technology at Kaunas University of Technology. Tensile and cycle flexing–abrasion tests as well as tests of enervated threads were performed. The results demonstrated that thermo-setting of tested threads has an influence on the tensile characteristics of threads. The parameters of manufacture process – overfeed and air pressure, have a great influence on the tensile characteristics of the air-jet textured threads.
