Interminded sewing-thread consisting of two components, and method for producing the same

摘要

A two-component loop sewing thread comprising core and effect filaments of high strength and low shrinkage composed of synthetic polymers, with the exception of polyester, is described which has an intrinsic viscosity (measured in solutions in dichloroacetic acid at 25 DEG C) of greater than 0.65 dl/g, having a final strength of over 40 cN/tex, a heat shrinkage at 180 DEG C of less than 8% and a maximum extension under load of less than 18%. This thread has a total denier of 200 to 900 dtex, its core filaments and effect filaments are present in a weight ratio of 95 : 5 to 70 : 30 and the filament titre of the core filaments is 8 to 1.2 dtex and that of the effect filaments 4.5 to 1 dtex.
