ULTRAWEICHES FLACHES MULTIFILAMENTGARN UND DESSEN HERSTELLUNGSVERFAHREN. |
摘要 |
<p>An extremely soft, flat multi-filament yarn having unique feeling can be obtained by stretching at least two kinds of multi-filament yarns having different stretchability, subjecting them to temperorary twisting for applying twisting and detwisting at a temperature of up to 120 DEG C and heat-treating the composite yarn thus themporarily twisted at a temperature above 130 DEG C in any of subsequent steps. The high elongation multi-filament yarn produced from high stretchable multi-filament in this multi-filament yarn has a degree of crystallization of 10 % to 30 % (density method), the degree of orientation at an amorphous portion of 0.035 to 0.10, a density of the amorphous portion of 1.31 to 1.36 g/cm<3> and Young's modulus of 200 to 700 kg/mm<2>.</p> |
