Abstract (en)
An elastic core and sheath type composite filament composed of a thermoplastic non-elastomer sheath component, such as polyamide, copolyester and polyolefin, and a crosslinked polyurethane core component, preferably predominantly allophanate-crosslinked, wherein a core/sheath conjugate ratio (X) and a crosslink density (Y mu mol/g) of the polyurethane satisfy simultaneously the inequalities: 3 </= X </= 100, Y >/= 0 and Y >/= -8.7X + 52. The filament of the invention free from tackiness and excellent in elastic stretch recovery, heat resistance, and workability in knitting or weaving, can provide textile structures of high quality, for example, high-stretchable, support type stockings with good appearance and tactile properties.
