However, early superhero comics predate the invention of spandex (Superman: 1938; Batman: 1939; Captain America: 1941). By the end of the 1980s and the decline of glam metal with the advent of grunge and thrash metal, spandex fell out of fashion and many older glam bands found themselves being referred to as spandex jockeys . While glam metal bands were getting into the spandex craze, so were many glam-oriented country stars, especially women like Dolly Parton, Margo Smith, Louise Mandrell, and Dottie West.

As the strands pass through the cell, they are heated in the presence of a nitrogen and solvent gas. Some of the rock/metal bands who used spandex leggings included Queen, Ratt, Van Halen, Mötley Crüe, Stryper, Judas Priest, Scorpions, Iron Maiden, Saxon, Whitesnake, Bon Jovi and Twisted Sister.

This is done by mixing a macroglycol with a diisocyanate monomer. In North America it is rare in men s clothing, but prevalent in women s.

Also, the stretchiness of the material did not constrict musicians movement onstage, allowing them to perform high kicks, or to rest their feet on monitors. Each fiber of spandex is made up of many smaller individual fibers that adhere to one another due to the natural stickiness of their surface. Step 5: The resulting fibers are then treated with a finishing agent which can be magnesium stearate or another polymer.

Dottie West is perhaps the best known of any country singer for wearing spandex disco jeans on stage. Star Trek: The Next Generation featured a wide use of spandex uniforms in its early series. The fibers are then transferred through a series of rollers onto a spool. Step 6: When the spools are filled with fiber, they are put into final packaging and shipped to textile manufacturers. In clothing it usually appears as a small percentage of total material.

It is usually mixed with a greater percentage of one other textile such as cotton or polyester. This causes the solution to be aligned in strands of liquid polymer.

This reduces the reflection of light to hardly noticeable levels. In comic books, superheroes and superheroines commonly wear costumes thought to be made of spandex. Printing processes for early color comics only rendered images with distinctly separate solid blocks of color well, because overprinting and color mixing yielded inconsistent results and bad looking muddy colors.

The solution dry spinning method is used to produce over 94.5% of the world s spandex fibers. Step 1: The first step is to produce the prepolymer. Once the prepolymer is formed, it is reacted further in various ways and drawn out to produce a long fiber.

This reaction is known as chain extension reaction. The first use of the material was in 1983 s Kagaku Sentai Dynaman. It is also used in the American adaption of Power Rangers, with which it has achieved popularity. During the 1970s and 1980s, spandex leggings rose in popularity among many rock and heavy metal bands, particularly British NWOBHM and American glam metal bands.

It is used more often in women s as their clothes are usually more form-fitting. Spandex is the preferred name in North America; in many European countries it is referred to as elastane . A brand name associated with spandex is Lycra (owned by Invista). Other spandex trademarks include Elaspan (also Invista s), creora (Hyosung), ROICA & Dorlastan (Asahi Kasei), Linel (Fillattice), and ESPA (Toyobo). Spandex fibers are produced in four different ways, including melt extrusion, reaction spinning, solution dry spinning, and solution wet spinning.

The main reasons for this massive, almost universal, embracement of spandex among rock/metal bands was because spandex retained its stretchy, tight fitting quality, even after extended wear. This process causes the liquid polymer to react chemically and form solid strands. Step 4: As the fibers exit the cell, an amount of solid strands are bundled together to produce the desired thickness.

In this cell, the polymer solution is forced through a metal plate called a spinneret. The solvent helps make the solution thinner and more easily handled, and then it can be pumped into the fiber production cell. Step 3: The spinning solution is pumped into a cylindrical spinning cell where it is cured and converted into fibers.

Denim jeans and leather strides tended to sag and wear, while spandex did not. All of these methods include the initial step of reacting monomers to produce a prepolymer.

Spandex, Lycra or elastane, is a synthetic fiber known for its exceptional elasticity. A typical ratio of glycol to diisocyanate is 1:2. Step 2: The prepolymer is further reacted with an equal amount of diamine.

This treatment prevents the fibers sticking together and aids in textile manufacture. The same assumption of costume composition is also made for latex and rubber garments, which are also typically solid in color and skin-tight. In Japan, spandex is the common material for costumes used in the popular Super Sentai series.

It is stronger and more durable than rubber, its major non-synthetic competitor. Later on, those uniforms were replaced by more classical clothes. .

Because spandex is skintight, as many superhero costumes appear to be drawn, and because spandex is almost exclusively made in similarly bright solid colors, the after-the-fact assumption of spandex composition was made. The resulting solution is diluted with a solvent to produce the spinning solution.

When first introduced, it revolutionized many areas of the clothing industry. The product name Spandex was given to the Spanjian family after DuPont recognized their contributions. The two compounds are mixed together in a reaction vessel to produce a prepolymer.
