CONTINUOS PROCESS FOR SINNING AND DRAWING POLYAMIDE AND APPARATUS THEREOF

摘要

In the production method for polyamide filaments with low contractility and high crystallinity and with high content of crystals ( the melting is continually spinned, the filaments are cooled, seasoned and thermally processed in the steam and thermal unit before lengthening and optional shaping. The steam and thermal unit comprises a steam box (6), first stepped galette (5) and second stepped galette (7).
