Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk. Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis yielding materials such as nylons, aramids, and sodium polyaspartate. Synthetic polyamides are commonly used in ...
Microfiber fabrics are man-made and frequently used for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture (perspiration) away from the body; subsequent evaporation cools the wearer. Microfiber can be used to make tough, very soft fabric for clothing, often used in skirts, jackets, bathrobes, and swimwear.
Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6, are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name. [1]
At present, polyamide 6 is a significant construction material used in many industries, for instance in the automotive industry, aircraft industry, electronic and electrotechnical industry, clothing industry and medicine. Annual demand for polyamides in Europe amounts to a million tonnes. They are produced by all leading chemical companies.
Qiana is described in U.S. patent 3249591 as a polyamide fabric having improved resilience and silk-like hand, combined with superior wash-wear performance. The polymer is prepared from 4,4'-diaminodicyclohexylmethane and dodecanedioic acid. [3]
The term, blend, refers to spun fibers or a fabric composed of such fibers. [1] [3] There are several synonymous terms: a combination yarn is made up of two strands of different fibers twisted together to form a ply; [1] a mixture or mixed cloth refers to blended cloths in which different types of yarns are used in warp and weft sides.

Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids. [2]
Lamé is a type of brocaded clothing fabric with inwoven metal threads, typically of gold or silver, giving it a metallic sheen. lawn Lawn is a fine linen or cotton cloth. linen Linen is a material made from the fibers of the flax plant. Linens are fabric household goods, such as pillowcases and towels, many of which were historically made from ...
