The analysis of the seam strength characteristics of the PES‐PTFE air‐jet‐textured sewing threads

Abstract Purpose – The goal of the research presented is to analyse seam strength properties of polyester and polyester‐polytetrafluoroethylene air‐jet textured sewing threads. Design/methodology/approach – These threads are designed for sewing various garments and are manufactured by the Department of Textile Technology at Kaunas University of Technology. Manufacturing parameters are varied during air‐jet‐texturing, which includes air pressure, effect and core yarns overfeed. Tensile tests of sewing threads and seams strength tests are performed. Findings – They indicate that the strength of seams depends on the properties of sewing threads. Originality/value – Analysis of the seam strength of PES‐PTFE air‐jet‐textured sewing threads.
