    摘要: Two-component loop yarns composed of core and effect filaments are made of synthetic polymers and comprise the following features. At least some of the effect filaments are made of polyester, and at least some of the effect filaments have a breaking extension of from 35 to 70%, preferably from 35 to 60%. Moreover, at least some of the effect filaments have a birefringence of from 100*10.sup.-3 to 150*10.sup.-3, in particular from 125*10.sup.-3 to 140*10.sup.-3, and at least some of the effect filaments have a hot air shrinkage of 200.degree. C. of from 3 to 14%, in particular from 5 to 10%. The effect filaments have a filament linear density of not greater than 1.5 dtex.
