Abstract (en)
[origin: EP0664352A1] A bicomponent yarn is made from core filaments and from effect filaments which are formed into surface loops. At least some of the effect filaments are made from polyester with a max. extensibility of 35-170% pref. 35-60%, a birefringence of 100 x 10<-3> to 150 x 10<-3> esp. 125 x 10<-3> to 140 x 10<-3>, a thermal shrinkage at 200 degrees C of 3-14%, esp. 5-10% and each filament is less than 1.5 dtex. Also claimed is a process of melt spinning with cooling of the filaments followed by reheating and drawing due to friction with a surrounding gas. Two or more gps. of filaments are then led at different speeds to a texturing jet where they are intermingled and the surface loops are formed. The yarn is then heat set under tension. The difference in feed speeds and the heat setting conditions are arranged so that the effect filaments comprise at least 25 wt.%.
