3. Processing section

3.1 Process flow

Precursor fiber tow → Creel & upper & lower guide frames → Oil immersion bath → 1^st draw stand → bath draw chest → 2^nd draw stand → steam draw chest → 3^rd draw stand → stacker → tension frame →steam pre-heater → crimper → spreader → tensionless tow dryer → draw-off tension stand → cutter → baler for stapled fiber.
