Which structural factors effects on fiber properties?
Ans:
Chemical bonding:
a)Double bond
More strength, less flexibility
b) Single bond
Less strength, more flexibility
Character of polymer chain:
a) Long chain, such as [-CH2-CH2-CH2-CH2-CH2-CH2-]n
More strength, less flexibility
b) Short chain, such as [-CH2-CH2-]n
Crystallinity:
High crystalline, higher strength and less flexibility
Orientation:
High Orientation, higher strength and less flexibility
Nature of Monomer:
a) Same monomer (Homo polymer)
More strength, less flexibility
b) Different monomer (Co-polymer)
Less strength, more flexibility
Les strength, more flexibility
c) Long side chain
More strength, less flexibility
d) Short side chain
Less strength, more flexibility
