Cordura Nylon vs. Cotton Duck: Analyzing Abrasion and Thermal Failure

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 mechanically distinct from standard canvas due to its 2x2 plied yarn weave. This dense structure, found in our Number 1 Heavyweight Duck, resists punctures and snags better than looser weaves. Critically, cotton is cellulosic. It chars at high heat but never melts. This thermal safety profile is why industrial tradesmen rely on duck cloth. For weather protection, untreated cotton absorbs water, but applying wax transforms it. Our Waxed Canvas Army Duck offers excellent water repellency while developing a rich patina that synthetic 500 Denier Cordura cannot replicate. Synthetics often suffer from hydrolysis and coating failure after a decade, whereas cotton softens and improves with age. If your new gear feels too rigid, our guide on how to soften stiff duck cloth explains how to break it in quickly.

Select Cordura for weight savings and wet environments. Select Canvas Duck for fire safety and breathability. You can compare these textures directly by ordering printed fabric swatches before starting your next project.

Pertussis Infection in Adults | Infectious Diseases | JAMA | JAMA Network

cuidado con toses prolongadas.

"Among adults presenting with prolonged cough, the estimated prevalence of pertussis is 12% to 32%.5 Compared with adults without airway disease, those with asthma and chronic obstructive pulmonary disease are at increased risk of acquiring pertussis and more severe disease.6 Obesity is also a risk factor for acquiring pertussis, and those who are immunocompromised or smoke cigarettes are at higher risk for severe disease.6"
