Abstract (en)
[origin: WO2004048650A1] The present invention relates to a high shrinkage side-by-side type composite filament, wherein two kinds of thermoplastic polymers are arranged side by side type and a boiling water shrinkage (Sr2) measured by the method (initial load = notified denier x 1/10g, static load = notified denier x 20/10g) of clause 5.10 of JIS L 1090 is 20 to 75% of a boiling water shrinkage (Sr1) measured by the method (initial load = notified denier x 1/30g, static load = notified denier x 40/30g) of clause 7.15 of JIS L 1013. The side-by-side type composite filament. is made of two kinds of thermoplastic polymers having a number average molecular weight difference (ïMn) of 5,000 to 15,000 upon spinning and the composite filament is drawn and heat-treated so as to satisfy the following physical properties: Temperature area exhibiting 95% of maximum thermal stress (Tmax, 95%): 120 to 230°C Range of maximum thermal stress per denier : 0.1 to 0.4g/denier
