Choosing between Cordura and Canvas Duck requires analyzing how each material fails under stress. As your fabric supplier, we knows that Cordura (Nylon 6.6) excels at resisting abrasion and water, making it the superior choice for lightweight tactical gear. Canvas Duck (Cotton) , with its plied yarn construction, dominates in heat resistance and breathability, making it mandatory for welders and industrial workwear. Cordura is an air-jet textured nylon filament designed to slide. In laboratory Wyzenbeek abrasion testing , our 1000 Denier Nylon withstands over 300,000 double rubs. The synthetic filaments refuse to break under friction, whereas natural fibers eventually grind away. This makes nylon the correct specification for motorcycle skid zones or backpack bases. However, this strength comes with a thermal weakness. Nylon is a thermoplastic that melts at approximately 255°C. If you expose it to welding slag or a campfire, it melts and fuses to skin. Canvas Duck is mechanicall...
