CORDURA's pivotal shift to nylon occurred in 1966. This transition was driven by a fundamental leap in material science; newly developed formulations of nylon were proven to be vastly superior in strength and durability compared to the fabric's original rayon composition.
The change from rayon to nylon was not merely an upgrade—it was the defining moment that established the CORDURA brand's identity. This strategic move leveraged nylon's inherent abrasion resistance and toughness, setting a new standard for high-performance textiles that continues to this day.

The Genesis of CORDURA: A Material Evolution
To understand the importance of this change, we must first look at the material CORDURA started with and the technological breakthrough that prompted the switch.
The Original Material: Rayon
CORDURA was initially developed by DuPont as a type of rayon, a fiber derived from regenerated cellulose. While strong for its time, rayon had inherent limitations, particularly when compared to the synthetic polymers that were emerging.
The Catalyst for Change: Nylon's Breakthrough
The 1960s saw significant advancements in polymer chemistry. New formulations of nylon, a fully synthetic polymer, demonstrated properties that were a dramatic improvement over existing fibers.
This new material offered a level of tensile strength and abrasion resistance that rayon simply could not match, making it the clear choice for demanding applications.
The Defining Year: 1966
Recognizing this technological advantage, the brand officially transitioned the CORDURA product line to these superior nylon formulations in 1966. This single decision charted the course for the brand's future.
Understanding the Material Superiority
The term "superior" isn't just marketing; it reflects fundamental differences in the materials' molecular structure and resulting physical properties.
What Made Nylon a Better Choice?
Nylon fibers are exceptionally strong, tough, and resistant to damage from abrasion, insects, and chemicals. Its long-chain polymer structure is inherently more robust than the processed cellulose fibers of rayon.
This meant that products made with nylon CORDURA could withstand far more punishment, last significantly longer, and perform more reliably in harsh conditions.
From Tire Cord to Tactical Gear
Originally engineered for use in tires, CORDURA's transition to nylon unlocked its potential for a much broader set of applications.
The unmatched durability made it the ideal material for products where failure was not an option, such as military packs, outdoor gear, and protective apparel—the markets it dominates today.
The Impact of This Strategic Shift
This was more than a simple material substitution; it was a strategic pivot that had a lasting impact on the entire textile industry.
Why Not Start with Nylon?
The specific nylon formulations that gave CORDURA its legendary toughness were simply not available or perfected when the brand was first conceived. The 1966 transition was a direct result of innovation making a better material commercially viable.
The Legacy of the 1966 Transition
By embracing the best available material science, CORDURA cemented its reputation. The brand became synonymous with durability because of its early and decisive commitment to high-performance nylon. This move set a benchmark for rugged textiles that competitors have chased for decades.
What This Means for Material Selection
The history of CORDURA's transition offers a clear lesson in how material choice dictates performance and defines a product's value.
- If your primary focus is maximum durability: The CORDURA story proves that the base polymer, in this case nylon, is the true foundation of a fabric's performance characteristics.
- If you are evaluating a brand's reputation: Look for pivotal technical decisions in its history, as the 1966 shift demonstrates how a commitment to superior materials creates a lasting legacy of trust.
Ultimately, CORDURA's transition to nylon is a powerful example of how embracing material innovation is the key to creating a legacy of unparalleled performance.
