Then the prepolymer is reacted further, in various ways, and drawn out to produce a long fiber. For example, it has been found changing the starting pre-polymers can further improve the fiber’s stretching characteristics. When the two types of prepolymers are mixed together, they interact to form the spandex fibers. ." Compounds which inhibit fiber discoloration caused by atmospheric pollutants are another type of stabilizer added. In the 1990s a variety of other items made with Spandex proved popular, including a successful line of body-shaping foundation garments sold under the trade name Bodyslimmers.

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. In this cell, the. Chemically, it is made up of a long-chain polyglycol combined with a short diisocyanate, and contains at least 85% polyurethane. What are Some of the Characteristics and Applications of Spandex? Spandex is used in a wide range of garments due to its high elasticity and significant strength. Spandex is a synthetic fabric that is prized for its elasticity. The important feature of these molecules is that they are long and flexible. This is done by mixing a macro, 2. Here, the fibers may be woven with other fibers such as cotton or nylon to produce the fabric that is used in clothing manufacture. The prepolymer is further reacted with an equal amount of, 3. One of its most valued properties that cannot be found in nature is its extraordinary elasticity. fiber is Invista's Some of the rigid portions of the polymers bond with each other and give the fiber structure. the In the fiber, this molecule provides strength. Clothing definitions and Glossaries: can be stretched It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia. Brand names for spandex include Lycra (made by The Lycra Company, previously a division of Invista. [11] DuPont was not ready to abandon a market that they were significantly reliant on. Since it is lightweight and does not restrict movement, it is most often used in athletic wear. Licorice is a glossy, gelled candy with a semi-firm consistency that is flavored with licorice root extract. The spinning solution then goes into a cylindrical spinning cell. commercial This network prevents the polymer chains from slipping past each other and taking on a permanent set or draw.

Adds comfort to clothes thanks to its soft, smooth and lightweight feel, Does not get affected by harsh detergents of regular washes, Spandex does not get affected by ultraviolet rays. 3 The spinning solution is pumped into a cylindrical spinning cell where it is cured and converted into fibers. You have entered an incorrect email address! The amorphous segments remain in an elongated state. synthetic The solution dry spinning method is used to produce over 94.5% of the world's spandex fibers,[10] and the process has five steps: In the post World War II era, DuPont Textiles Fibers Department, which was formed in 1952, became its most popular division, dominating the synthetic fiber market worldwide. All Rights Reserved. Different blends of spandex with conventional fibers are expected to produce higher-quality fibers. Second, they are lightweight, soft, and smooth. The windup speed of the entire process can be anywhere from 300-500 mi (482.7-804.5 km) per minute depending on the thickness of the fibers. Currently, nylon/spandex fiber blends are available. Since their discovery, the quality of the spandex fibers keeps improving and getting better. As the decade progressed shirts, pants, dresses, and even shoes were being made with spandex blends, and mass-market retailers like Banana Republic were using it for menswear.
