"A monofilament has what is called low tissue drag, meaning it passes smoothly through tissue. Braided or twisted sutures may have higher tissue drag, but are easier to knot and have greater knot strength. Braided sutures are usually coated to improve tissue drag.

"Tensile strength is the breaking strength of a suture material per unit area.
Memory is a suture material’s tendency to retain original configuration.
‘Chatter’ and tissue drag is the lack or smoothness or amount of friction whilst
passing through tissue."

"Biosyn and Monocryl. These sutures have similar properties to Dexon, Polysorb and Vicryl however they are monofilament. They were developed to overcome the problem of tissue drag and knot slipping found in the braided synthetic absorbables. [...]
These materials pass through tissue with essentially no tissue drag and have excellent knot tying security at sizes 3-0 to 5-0."
