Nylon, one of the most transformative synthetic fibers in modern history, revolutionized industries ranging from fashion and textiles to engineering and aerospace. Before its invention, fabrics relied on natural fibers like cotton, silk, and wool, which had limitations in strength, elasticity, and durability. Nylon changed everything by introducing a material that was lightweight, versatile, and incredibly strong, shaping consumer products and military equipment alike.
Nylon was developed in 1935 by Wallace Hume Carothers and his team at DuPont. It became commercially available in 1939, first used in toothbrush bristles and women’s stockings before expanding into parachutes, ropes, and industrial materials during World War II. Nylon’s invention marked the birth of the synthetic polymer era, influencing countless industries with its strength, elasticity, and affordability.
What began as a laboratory experiment soon turned into a global material revolution, making nylon a household name. And behind this scientific breakthrough lies a story of chemistry, wartime necessity, and industrial ambition—let’s explore it step by step.
What Is Nylon and Why Was It Invented?
When we talk about synthetic fibers that transformed the modern world, nylon deserves a place at the top of the list. Today it appears everywhere—from clothing, backpacks, and seatbelts to automotive components, medical devices, and aerospace engineering. But to understand why nylon was invented, we must look at the scientific ambitions, economic challenges, and technological limitations of the early 20th century.
Before the 1930s, most fabrics came from natural sources:
- Cotton and wool were widely available but heavy, moisture-absorbent, and slow-drying.
- Silk was prized for its softness and strength but was expensive, labor-intensive to produce, and imported mainly from Asia.
- Materials like linen or hemp were used for ropes and sails but lacked versatility for modern industrial needs.
The Great Depression and geopolitical tensions amplified these issues. Import restrictions, fluctuating prices, and the looming threat of war pushed both governments and industries to seek domestic, affordable, and reliable alternatives to natural fibers—particularly silk, which was critical for parachutes, ropes, and military gear.
Enter DuPont, a chemical company aiming to transform its image from a gunpowder manufacturer to a scientific innovator. In 1928, DuPont established a fundamental research laboratory in Wilmington, Delaware, under the leadership of Dr. Wallace Hume Carothers, a Harvard-trained chemist. The lab’s mission was ambitious:
- Explore new synthetic polymers through cutting-edge organic chemistry.
- Develop materials with properties rivaling or exceeding natural fibers.
- Create mass-producible materials to fuel emerging consumer and industrial markets.
Carothers and his team began experimenting with long-chain molecules capable of forming fibers when cooled or drawn out. After years of research, they discovered polyamide 66, a polymer with remarkable properties:
- High Tensile Strength: Stronger than silk, capable of withstanding mechanical stress.
- Elastic Recovery: Stretched fibers returned to shape, ideal for garments.
- Moisture Resistance: Absorbed far less water than cotton or wool, reducing mildew risk.
- Thermoplastic Behavior: Could be melted, molded, and spun into fibers or solid parts.
Initially known in technical papers as “polyamide 66”, the material received its commercial name—nylon—just before its 1939 launch.
But nylon wasn’t only about chemistry; it reflected social and economic ambitions:
- For consumers, it promised affordable stockings that mimicked silk but lasted longer.
- For the military, it offered a strategic substitute for imported silk in parachutes, tents, and ropes.
- For manufacturers, it opened doors to plastics and fibers engineered for performance, not limited by nature.
When DuPont unveiled nylon stockings at the 1939 New York World’s Fair, the response was explosive: 4 million pairs sold in four days. The press called it a “miracle fiber,” and women nicknamed it “strong as steel, fine as a spider’s web.” Within a few years, nylon shifted from consumer novelty to wartime necessity, especially after Japan cut off silk exports to the U.S. during World War II.
In short, nylon was invented to solve the limitations of natural fibers while fueling industrial progress, military readiness, and consumer demand. It marked the dawn of the synthetic polymer era, paving the way for materials like polyester, Kevlar, and modern engineering plastics that define our world today.
| Property | Silk | Cotton | Nylon 6,6 |
|---|---|---|---|
| Strength (MPa) | 400–600 | 300–500 | 650–900 |
| Elasticity | Moderate | Low | High |
| Moisture Absorb. | 11% | 25% | <4% |
| Cost (1939) | Very High | Moderate | Low |
When and Where Was Nylon First Developed?
Nylon was officially developed in 1935 at DuPont’s Experimental Station Laboratory in Wilmington, Delaware, USA. But behind this single sentence lies a fascinating story of science, industry, and global transformation—a tale that links a Harvard chemist, a chemical company seeking reinvention, and the urgent needs of a changing world.
The key figure was Dr. Wallace Hume Carothers, a brilliant but introverted organic chemist who joined DuPont in 1928 to lead its newly established fundamental research division. At that time, DuPont was transitioning from being primarily a gunpowder and chemical explosives company into a diversified materials innovator. The company had tasted success with cellophane and rayon, but it sought a completely synthetic fiber that could surpass natural materials in strength, durability, and performance.
By the early 1930s, the world faced economic depression and geopolitical uncertainty. Natural silk, primarily imported from Japan and China, was expensive and geopolitically vulnerable. Its strategic importance was clear: silk was essential for parachutes, ropes, and military gear, but Japan’s growing militarism threatened U.S. supplies. At the same time, consumer markets demanded affordable, durable, and modern textiles for fashion and home goods.
Carothers and his team focused on polymer chemistry, specifically long-chain molecules capable of forming fibers when drawn out and cooled. On February 28, 1935, after hundreds of experiments, they successfully produced a polyamide polymer with exceptional properties:
- Strength: It rivaled silk in tensile durability.
- Elasticity: It stretched and recovered without breaking.
- Moisture Resistance: Unlike cotton or wool, it absorbed very little water.
- Thermoplasticity: It could be melted, molded, and reprocessed.
But scientific discovery was only the first step. DuPont immediately recognized its commercial and military potential. In 1938, the company introduced nylon publicly at the New York World’s Fair, branding it as “a miracle fiber”. By 1939, nylon stockings hit the U.S. market, sparking a retail sensation—4 million pairs sold in just four days. Newspapers dubbed it the “nylon frenzy,” showing how quickly science could capture consumer imagination.
World War II, however, transformed nylon from a fashion novelty into a strategic military asset. When Japan cut off silk exports in 1941, nylon became indispensable for:
- Parachutes → over 3 million nylon parachutes produced for Allied forces
- Ropes and Cords → lighter yet stronger than hemp or cotton alternatives
- Tents and Uniform Reinforcements → quick-drying, mildew-resistant fabrics
- Aircraft Tire Cords → replacing silk in critical components
By 1945, DuPont factories were producing tens of millions of pounds of nylon annually, much of it dedicated to wartime needs. Only after the war did nylon return to civilian markets, where it became a staple for clothing, carpets, luggage, and industrial products.
Geographically, nylon’s birthplace in Wilmington became a symbol of American industrial science. DuPont’s Experimental Station was hailed as a model for corporate-funded fundamental research, blending academic freedom with commercial focus—a concept later emulated by companies like IBM, Bell Labs, and 3M.
How Has Nylon Evolved Since Its Invention?
Nylon’s invention in 1935 marked the birth of the synthetic polymer era, but its story didn’t stop there. Over nearly a century, nylon evolved from being a fashion sensation to a wartime necessity, and eventually into a high-performance engineering material shaping industries as diverse as automotive, aerospace, electronics, and sustainable fashion.
The evolution of nylon can be divided into five major phases, each driven by new applications, technological improvements, and changing global priorities.
