Is Nylon Stockings Day a public holiday?

No. It is an unofficial observance, not a federal or public holiday, so businesses and schools stay open.

Who started Nylon Stockings Day?

The May 15 date points to the documented 1940 nylon debut, which is the day's reference point. No founder, organization, or proclamation is on record for the observance itself.

Is Nylon Stockings Day the same as National Legwear Day or National Sock Day?

No. National Legwear Day is September 22 and National Sock Day is December 4. Only Nylon Stockings Day, on May 15, points back to the nylon debut.

Did nylon really get its name from New York and London?

No. That story is false, and London played no part. The name reportedly evolved from a proposed "Nuron" to "Nilon" to "nylon."

HOW THE HOLIDAY CAME TO BE

A debut day with no documented author.

No documented founder or formal establishment record has been identified for the observance itself. The May 15 date commemorates a real event: on May 15, 1940, DuPont's nylon stockings went on sale across the United States, and nearly 800,000 pairs sold the first day. The day is sometimes called N-Day or Nylon Day.

INTRO

The chemist who never saw nylon conquer the market

Wallace Carothers did not live to see the day this holiday marks. The DuPont chemist led the team that invented nylon, the world's first fully synthetic fiber. In April 1937, he took his own life, two years before the fiber went into production and three years before nylon stockings became a national sensation.

Nylon Stockings Day, observed on May 15, sits at the far end of that story. It commemorates the morning in 1940 when the stockings finally reached store counters from coast to coast. The man most responsible for them had been gone for three years.

The frenzy did not stop at the debut. After the war pulled nylon off civilian shelves, the shortage turned customers into crowds. In 1946 the lines outside one Pittsburgh store stretched for a mile, and a local headline called the scene a "Nylon Mob".

ORIGINS

Nylon Stockings Day history

INTRODUCTION

Nylon Stockings Day reaches back to a research bet DuPont placed in the late 1920s. The company hired Wallace Hume Carothers in 1928 to run fundamental research at its Wilmington lab. He arrived as an academic chemist, not a product man, and DuPont gave him room to chase polymers with no clear payoff in sight.

The payoff came on February 28, 1935. Carothers's team built a fiber from two carbon-rich compounds, adipic acid and hexamethylenediamine, and called it "fiber 66." The name marked the six carbon atoms in each starting material. DuPont picked it for full production that July.

CHAPTER 01

The invention outlives its inventor

Carothers had become the first industrial organic chemist elected to the National Academy of Sciences in 1936. He also lived with deepening periods of depression. In April 1937 he took his own life, two years before nylon went into production.

DuPont pressed ahead. On October 27, 1938, vice president Charles Stine unveiled the fiber in a nationwide broadcast from New York. Marketing soon called nylon "strong as steel and delicate as a spider's web," a slogan, not a line anyone spoke at the event.

CHAPTER 02

From a three-hour sellout to a national debut

DuPont tested demand before going wide. In late October 1939 a limited public sale in Wilmington, Delaware moved its roughly 4,000 pairs in about three hours. The real launch followed on May 15, 1940, when stockings went on sale nationwide. Crowds emptied counters from coast to coast.

Then the country went to war. After Pearl Harbor, the War Production Board commandeered DuPont's nylon in early 1942 and redirected it to parachutes, tire cords, ropes, and netting. The fiber earned a new nickname, "the fiber that won the war."

CHAPTER 03

The shortage that made a holiday

Peace did not bring stockings back overnight. Pent-up demand met thin supply, and the "nylon riots" broke out in 1946. By that March, DuPont had pushed output to about 30 million pairs a month, and the shortage finally eased.

The product's history is well documented. The observance's is not. No founder, proclamation, or registrar is on record for Nylon Stockings Day itself. The May 15 date carries the weight, pointing back to the 1940 debut rather than to anyone who later put the day on a calendar.

TIMELINE

Timeline

Fiber 66 is synthesized

Carothers's team made the signature fiber on February 28, and DuPont chose it for full-scale production that July.

Carothers dies

The lead chemist took his own life in April, two years before nylon reached the market.

DuPont unveils nylon

Vice president Charles Stine announced the new fiber on October 27 in a nationwide broadcast from New York.

Nationwide debut

On May 15, nylon stockings went on sale across the country, and nearly 800,000 pairs sold the first day.

War takes the nylon

The War Production Board commandeered DuPont's nylon in early 1942, pulling stockings from civilian shelves for the war effort.

The nylon riots

About 40,000 people lined up in Pittsburgh on June 12 for roughly 13,000 pairs as production raced to catch up.

GOOD TO KNOW

Surprising facts about Nylon Stockings Day

The first experimental stockings came out black

The Smithsonian holds the first pair of experimental nylon stockings, made for DuPont in 1937. The nylon would not take the silk dye, so the leg came out black instead of brown.

Women painted stockings onto bare legs

During the wartime shortage, women brushed on "liquid stockings" leg makeup, sometimes mixing gravy browning or cocoa with lotion, then drew a fake seam down the back of the leg with an eyebrow pencil.

DuPont chose not to trademark the word

The company kept "nylon" as a generic name for the class of polymers. The word reportedly evolved from a proposed "Nuron" to "Nilon" to nylon.

The name is not New York plus London

A popular story claims "nylon" blends "New York" and "London." Snopes rates it false, and London played no part.

Output hit 30 million pairs a month

After the 1946 riots, DuPont ramped production to roughly 30 million pairs of stockings monthly, which finally ended the shortage.

WHY THIS DAY MATTERS

Why Nylon Stockings Day Matters

MARKET

A lab fiber took a third of the stocking market in a year.

Within a year of the debut, nylon held more than 30 percent of the US hosiery market. It displaced silk, much of it imported from Japan, as the default fiber in American stockings.

CLASS

It records a flashpoint over scarce goods

The postwar nylon riots turned a consumer product into a story about work and class. The Pittsburgh sale was advertised to working girls, and scholars still study the episode.

WARTIME

It traces a fabric drafted into combat

When the military needed parachutes and ropes, nylon left store shelves and went to the front. The same fiber sold for fashion in 1940 was reclassified as a strategic material by 1942.

The Smithsonian's National Museum of American History catalogs the first experimental pair from 1937. Read the object record to see why the leg came out black.

READ

Read the chemistry behind the fiber

The American Chemical Society's landmark page walks through how Carothers's team built fiber 66. It is the clearest short account of how nylon came to be.

LOOK

Look up the nylon riots of 1946

Search out contemporary newspaper accounts of the postwar stocking lines. The crowds, the headlines, and the mile-long queues show how scarce the fiber became after the war.

COMPARE

Compare the day to other hosiery observances

Note how Nylon Stockings Day differs from National Legwear Day in September and National Sock Day in December. Only this one points back to the 1940 nylon debut.
