Process for melt-spinning a splittable conjugate filament; self-texturing splittable conjugate filament; and method of splitting such a filament. |
摘要 |
<p>Self-texturing sub-filaments split from a conjugate filament. The conjugate filament is melt spun from dissimilar polymers, the spinning and quenching conditions being selected such that the conjugate filament has no substantial crimp while the sub-filaments split therefrom have substantial latent torqueless helical crimp. Preferably the conjugate filament is hollow. A preferred spinneret blank 22 has horse-shoe shaped slots 20 with recessed web regions 24. Two dissimilar polymers are fed as a sheath-core conjugate stream with polymer interface 20.</p> |
