Process features & characteristics of Japan exlan fiber
|
 | |
Continuous aqueous suspension polymerization 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 spinneret 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 is applied for antistatic purpose 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.
