Bonding fuses the three plies together, so the thread does not fray or break at industrial sewing speeds and the seam keeps the abrasion resistance that upholstery, leather and canvas work demands.

Untreated nylon loses strength when it is left in direct sunlight, and on outdoor work the thread almost always fails before the fabric does — which means restitching a cover or an awning that is otherwise perfectly good. The treatment is there to push that failure point back.\u003c\/p\u003e\u003cp\u003eIt keeps everything that makes bonded nylon 66 worth using: high tenacity for its diameter, abrasion resistance, and a bonding agent that stops the plies fraying at industrial speeds. It adds resistance to prolonged sun exposure, moisture and mildew.\u003c\/p\u003e\u003ch3\u003eBeing straight about the limits\u003c\/h3\u003e\u003cp\u003eWe are not going to quote you a number of years in the sun, because we have no laboratory certificate for this thread and everyone who does quote one either has that certificate or is guessing.

This UV-treated nylon is the right choice when you want nylon's strength and abrasion resistance on work that lives outdoors, at a fraction of that cost.
