However, some people call it Elastane. The lightweight and the nearly invisible nature of this fibre material makes it an active ingredient in our clothes. There are four different ways of producing these fibres. They are melt extrusion, reaction spinning, solution dry spinning, and solution wet spinning. Moreover, all these methods include the formation of a pre-polymer from reacting the monomers as the first step.
The major applications of this polymer material are due to its elasticity and strength. The most significant property of lycra is its ability to return to the original shape after stretching, and faster drying than ordinary fabrics. The applications are in apparel garments, compression garments, shaped garments such as bra cups, support hose, surgical hose, etc.
Neoprene is a form of synthetic rubber. It forms as a result of polymerization of chloroprene. This material has good chemical stability, and it can maintain its flexibility to a wide temperature range. There are two major ways that people sell this material; as solid rubber or in latex form. Neoprene, on the other hand, is prized for its particular resistance to weather and impact.
Due to their particular properties, each material is used for a different range of products. While both nitrile and neoprene display similar elastomeric properties, their differing chemical and physical characteristics make them useful for distinctly different applications and industries.
Nitrile rubber products are highly valued in the aerospace, defense, infrastructure, medical, and mobile equipment industries. Common nitrile product applications include:.
Neoprene is commonly used for rubber washers, gaskets, bushings, and tubing. Cordura is just a brand name, who make both Polyesters and Nylons yeah, confusing. The reason Cordura is talked about is that their fabrics are made from pretty high grade raw materials, and their backings are high grade, so the overall quality is high. What exactly is added to zippers to make it not get stuck? Is it the lining under the zipper? Loads of things can affect zippers. The biggest is how quality the zip brand is.
But then if a zip is sown in with uneven tension by a shit sower, it can get pulled on badly and not work well. If you have anything to add, please let us know in the comments!

Neoprene offers moderate resistance to oils and petroleum products, but provides significantly greater resistance to sunlight, ozone, and weather. Nitrile rubber has poor flame resistance. By contrast, neoprene provides very good-to-excellent resistance against the spread of flame. Nitrile is attacked by sunlight, ozone, and weather, but neoprene provides reliable resistance against these environmental conditions.
Yet neither rubber resists aromatics or ketones, two types of organic compounds. In mobile equipment and military vehicles, nitrile seals or gaskets are used in carburetor diaphragms, fuel systems, and hydraulic hoses. Nitrile also supports rubber-to-metal bonding, which makes it a good choice for applications in the processing industry.
Neoprene rubber resists fire and withstands sunlight, ozone, and weather.
