New polymer spandex
Transcript of New polymer spandex
*Lightweight and doesn't restrict movement
*Scientists use this to create fabrics with
desirable stretching properties
*Fabric is its primary use
*Can stretch over and over again and return
to original shape
*Lightweight, soft, and smooth *Started developing during World War II
*Farbenfabriken Bayer, and early
polymer pioneer, first produced spandex on
an experimental level
*Scientists at Du Pont and the U.S. Rubber Company finalized the development of
*First introduced under the brand name
*Du Pont is still the leader in
Spandex Production Spandex is made up of a soft rubbery segment and a ridged tough segment The soft rubbery segments are made up of ethyl groups with an oxygen on either side, this can vary on the exact value of X in the above diagram. This group is also called the Polyester group. 4 different processes
Each involve the initial step of reacting monomers
Dry spinning is used to produce over 90% of the world's spandex fibers Chemical make up slides (MLA Format): The hard ridged segments are groups of urethanes. This section limits the amount of fluidity and plastic flow. This amount of "toughness" is dependent on the N variable (representing any number) Polyester Polyester is a polymer composed of multiple repeated chemical groups linked together with ester groups http://www.britannica.com/EBchecked/topic/468484/polyester http://www.docbrown.info/page03/sms04.htm Urethanes http://0.tqn.com/d/chemistry/1/0/L/R/1/Urethane.jpg Urethane has a basic chemical structure of CO(NH2)OC2H5. It is made up of several ester groups. "Spandex Structure." Mason academic research system (mason.gmu.edu). N.p., n.d.

Objectives Identify the polymer spandex and it's chemical make up.
Develop a clear understanding of processing, cost of production, and commercial uses.
Clearly state whether spandex can be recycled or reused. http://www.madehow.com/images/hpm_0000_0004_0_img0166.jpg http://www.madehow.com/images/hpm_0000_0004_0_img0167.jpg Wet Spinning Work Cited
