Abstract (en)
[origin: EP0367938A2] In mfg. a yarn, or partic. sewing thread, using a multifilament core and a second cladding material which is in intersecting loops around the core, the core is multifilament(s) with a strength of 60-75 cN/tex and is passed directly to the fluid eddy stage for cladding without preliminary drawing. Pref. the core component, satd. with a fluid, is subjected to eddies with a forward slip of 1-9%, while the cladding yarn component is passed to the eddy cladding stage with a forward slip of 14-35% (20-30%). The pref. cladding yarn component is a preoriented multifilament POY, given an initial drawing round pref. a heated pin before eddying, using a pin temp. of 110-150 deg.C (120-140 deg.C). The preorientation gives a drawing ratio of 2-40% (10-25). The specific strength of the cladding yarn component is pref. 20-75 cN/tex, and esp. 30-45 cN/tex or 60-75 cN/tex. For effective dyeing, the titre of the filaments in the core is 2-5 dtex (2.5-4.0 dtex), and the cladding filaments are 0.8-5.0 dtex (1-4 dtex). An unmatted multifilament is pref. for the cladding. The ratio of the mass of the core to the cladding is 90:10-50:50 (85:15-70:30). The pref. viscosimetric determd. mol.wt. is greater than that of a standard chemical fibre by 5-50% (by 10-25%). The multifilament core of 16-300 filaments (24-96), has a combined titre of 100-1000 dtex (100-600 dtex).
