Core sections of a NIPS production line NIPS
Control parameters: dissolution temperature, stirring speed, deaeration time, and vacuum level. Ensure a homogeneous, bubble-free dope to avoid internal fiber defects.
Control parameters: draw ratio, drying temperature and time, winding tension. The draw ratio should be controlled at 1.5–3× to enhance mechanical properties;drying temperature should be tailored to the material to avoid embrittlement from overdrying.
