|
Continuous aqueous suspension polymerisation
of reactive ingredients in a precisely
controlled reactor system.
|
| |
|
|
Constant composition of polymer and close
control of molecular weight. |
| |
|
|
Polymer in water slurry dissolved with highly
concentrated solvent, deaerated, heated and
filtered to convert into dope suitable for
spinning. |
| |
|
|
Dope extruded through spinnerette in spin bath
filled with dilute coagulant to form gel fibre
which is washed, stretched and made void free to
provide a dense and compact structure of the
fibre. |
| |
|
|
Tow is crimped and heat set to acquire stress
and strain property. High quality finish applied
for antistatic and lubrication purpose. |
| |
|
|
Tow is dried, cut and baled as staple or
packed as tow as per requirement. |
| |
|
|
Weak solvent from spinning sent to solvent
recovery for purification and evaporation to
increase concentration of solvent for reuse at
dope. |
