Kevlar Fraying and Knot Setting

From the NAR Facebook Page:

Bill Lindsay Jr asked:
What are the disadvantages of twisted Kevlar thread, compared to braided? I know the big thing is fraying. Can you heat it up enough to keep it from fraying?

Wallace McDuffey responded:
I use Dritz Fray Check for cloth. It works great on Kevlar and reinforcing knots. It is flexable enough that it wont make it brittle when stressed.

This Fray Check should work very well. I also use white glues on frayed lines.
TIP: Never use Super Glues (CA) to stop a line from fraying. The thin glue will run up the line making it hard and brittle.
