Essential accessory to the panoply of the "perfect" woman, pantyhose, which was a product of "luxury" in the second world war, is undercover over time. Made by Du Pont de Nemours, the inventor of Nylon, in factories, pairs all first were sold by stores of Wilmington, Delaware, where was the headquarters of the chemical group. Causing a real fever procuring women wishing to frivolous things during this period of restriction: 4,000 pairs have passed three hours on the first day, October 24, 1939. A folly as only the residents of this town have, provided to carry a proof of domicile, be entitled to the prescribed three pairs! It was not until May 15, 1940, which was even baptized 'Nylon Day', so all us can appropriate that both popular accessory, which explode sales volumes: 4 million pairs in four days and 64 million a year.
Modern chemistry

Finer, stronger and cheaper than silk, pantyhose have become, in a Flash, the new garb worn by American and popular Hollywood actresses pinup. Like actress Betty Grable, who sold his own price of gold on the black market to help the war effort! This symbol of womanhood quickly crossed the Atlantic and provoked the envy of the French, is pulling down by American GI in Paris, the release.
One such craze could not go unnoticed in the eyes of a connoisseur, a certain Bernard Giberstein. His credo: democratize fashion with chic and cheap products. Yarn needle, the founder of weaving Bégy – champenoise society later Sunday, then the famous Dim – Mark decided to specialize his company in the production of pantyhose in 1952. Four years later, he will invent the first bottom seamless, avoiding women writhing to adjust the straight line. With a master asset: the simplified manufacturing process allows a mass production reduced costs. By exploiting the vein of Nylon which is woven in two materials, foam and the veil, the creator of Dim will quickly reach the jackpot: the production explodes to 120,000 pairs in 1966 to 78 million in 1968.
Yet, this synthetic material, the first of the modern chemistry, applications have become almost universal, almost never see the day. His scientific team, a Wallace Hume Carothers sought to unlocking the secrets of the composition of natural polymers such as cellulose, silk, or rubber. Obtaining nothing interesting, the team was about to abandon the idea of producing the silk synthetic, when one of them originating in a ball with a polymers manufactured in their laboratory, and then to be drawn on its surface to form a yarn. Surprised, he realized that more it stretched it, the matter was gaining in strength and took a silky appearance. As announced it publicly officials of Du Pont, October 27, 1938, the Nylon was born under the code name "polyamide 6.6", after fifteen years of R & D and invested $ 27 million. "We are entering the world of tomorrow", then declared Charles Stine, the Vice-Chairman of the group.
Bare legs
Seventy years ago the pantyhose has experienced ups and downs. After having peaked at 220 million pairs in the finest years in Dim, the current volume is around 80 million – the level of the 1970s – with the France list. The reason for this relative disaffection The mode of dress relaxation took hold, despite an uninterrupted series of innovations. As the Lycra, this elastic fibre able to stretch up to 7 times before returning to its original size, invented by Du Pont in 1962 and incorporated into pantyhose in the 1980s, which has brought them an incomparable comfort. In 1987, Dim innovates again by launching a new lower seamless, named Dim Up, taking just with a band of silicone in Garter. To re-brand the low stickiness, mark weaves more technical yarn, Nylon and polyurethane based, which give a sensation of bare legs, or with Microfiber as Lycra 3 D. By pulling on the thread of innovation, the market of the low sticker found, after a decline of 50 in ten years, its old appeal.
