The History of Nylon

The invention of nylon at E.I. duPont de Nemours, Inc. in 1934 began the explosion of completely synthetic materials that imitate natural materials into the fabric market. Nylon was created entirely from petrochemicals, unlike the previous artificial fabrics rayon and acetate, which were plant-based. Wallace Hume Carothers generally receives recognition for the invention, but another DuPont employee may have been the actual inventor. Julian Hill worked for Carothers, and had spent much time developing a process in which a long fiber with a silky texture could be created of carbon polymers. Carothers, who probably was afflicted with a severe bipolar condition, committed suicide in 1937, and the company credited the invention of nylon to him. Carothers had previously created neoprene, a synthetic rubber.

The synthetic fiber nylon was invented at the E.I. duPont de Nemours Company in Delaware, and nylon stockings became a big hit as soon as they were released. After a public supply cut-off during World War II, nylon stockings soared back in popularity more than ever. Nylon remains an important material today, used in a multitude of products.

Property of Nylon:Nylon is a generic designation for a family of synthetic polymers known generically as aliphatic polyamides, first produced on February 28, 1935, by Wallace Carothers at DuPont’s research facility at the DuPont Experimental Station. Nylon is one of the most commonly used polymers. Key representatives are nylon-6,6; nylon-6; nylon-6,9; nylon-6,10; nylon-6,12; nylon-11; nylon-12 and nylon-4,6

Chemistry of Nylon:Nylons are condensation copolymers formed by reacting equal partsof a diamine and a dicarboxylic acid, so that amides are formed at both ends of each monomer in a process analogous to polypeptide biopolymers. Chemical elements included are carbon, hydrogen, nitrogen, and oxygen. The numerical suffix specifies the numbers of carbons donated by the monomers; the diamine first and the diacid second. The most common variant is nylon 6-6 which refers to the fact that the diamine (hexamethylene diamine, IUPAC name: hexane-1,6-diamine) and the diacid (adipic acid, IUPAC name: hexanedioic acid) each donate 6 carbons to the polymer chain.

As with other regular copolymers like polyesters and polyurethanes, the "repeating unit" consists of one of each monomer, so that they alternate in the chain. Since each monomer in this copolymer has the same reactive group on both ends, the direction of the amide bond reverses between each monomer, unlike natural polyamide proteins which have overall directionality: C terminal → N terminal. In the laboratory, nylon 6-6 can also be made using adipoy chloride instead of adipic acid.The general reaction is:

Various Use of Nylon:

Nylon Sheet:

Nylon was the first

engineering resin and

has been used in

applications ranging

from electronic, marine,

and automotive

industries to fibers used

to make carpet. Nylon

Many people hang banners for holidays and special occasions, such as birthdays or anniversaries. Creating your own banners allows you to customize them to your particular event and taste. When making banners to hang outdoors, nylon fabric can be used to stand up to the elements. Nylon fabrics come in a variety of colors, maintain their shape and resist fading over time.

Nylon tow straps are lighter and more conveniently stored than the towing chains they have replaced for most applications. Tow straps are equipped with a steel hook on each end and should not be confused with recovery or snatch straps that have looped ends instead of steel hooks.

Whether you are supporting your favorite sports team, drawing attention to a political issue or just displaying your own personal independence, making your own flag out of nylon is a fairly easy process and is an inexpensive way to showcase your personal style. Decorative nylon flags are very easy to customize, and they are more durable and weather-resistant than cotton...and less expensive than polyester.

Nylon Ropes:Nylon ropes and cords are high strength and have

excellent UV and abrasion resistance. They are resistant to mildew, motor fuels, oils, cleaning fluids and many other chemicals. Do not float.

Nylon in Medical:

This is a synthetic polyamide material, which can be used in the

form of:

• Monofilament

• Multifilament

• Braided

The main disadvantage is that a triple knot must be tied.

Nylon Brush:Nylon filled industrial brushes are suitable for a range of applications from aggressive scrubbing to dusting, in both dry and wet environments. Brushes with Nylon fill offer the following characteristics in most applications: excellent fatigue life, good abrasion resistance, low to moderate absorption of water (3% to 9%) leading to only a temporary reduction in stiffness, an excellent bend recovery rate, resistance to most common solvents, and suitability for use in weak acids.
