Abstract
Degradation studies were conducted on high
performance polyamide (PA) 6 monofilament fibers
prepared with various types of thermoplastic thin
film coatings. Polyether, polyester and polycarbonate
based polyurethane thin film coatings were used
with changes in the molecular weight of the polyols
and NCO index. It was found that the thermoplastic
coating significantly protected the core PA6 monofilament
fibers from degradation, analyzed through
sliding abrasive wear and accelerated weathering
irrespective of the type and nature of the thermoplastic
polyurethane (TPU) thin film coating. The
structural and physical changes were analyzed after
exposure to degradation tests. Polycarbonate based
TPU thin film coated PA6 monofilament fibers
showed significant resistance towards degradation
factors as compared to the polyether and polyester
based TPU thin film coatings. The TPU thin film
coated PA6 monofilament fibers are potential
candidates as material for fishing gear
