Abstract (en)

[origin: EP1479802A1] A synthetic fibre sewing thread has a maximum tensile stretch of between 25% and 85%, and a maximum elongation elasticity of between 30% and 95%. Determination is made using a measuring force that is 70% of the absolute strength of the respective thread. Also claimed are two processes to make a commensurate sewing thread in which the thread is made either of doubled yarn or garn intermingled by air turbulence. In the manufacturing process, two or more yarn components are selected which have a maximum tensile stretch of between 25% and 85%, and a maximum elongation elasticity of between 30% and 95%. After the thread formation process, the thread is subjected to thermal and/or hydrothermal treatment process. One or both of the fibres are chemically-modified polyester fibres e.g. a multifilament poly-trimethylene-terepthalate. One yarn forms the core, while the second component is an air-formed fancy yarn.
