{{'''Polyamide}}6 and 6,6''' are manufactured, man-made fibres that are formed from a chemical process using carbon, hydrogen, oxygen and nitrogen atoms. They differ in that they each begin with different polymer building blocks.1 The manufacturing process of Polyamide 6 and 6,6 is highly chemical and is derived from petroleum, a non-renewable resource. Also, the fibre and its resulting fabric are non-biodegradable. Efforts to address sustainability in these areas could help the overall impact of polyamide on the environment.
'''== Benefits ==Polyamide fibers''' are synthetic fibers used in the manufacture 6 and Polyamide 6,6 share a lot of textilesthe same fibre characteristics. International Polyamid is often called [[nylon]]They have strong wear resistance, abrasion resistance, chemical resistance, heat resistance, are lustrous, have a high melting point, and are resilient. Originally nylon was 1Polyamide 6,6 has greater resilience, a brand that was launched by the fiber manufacturer [[DuPont]] in 1938 but higher melting point, and lower stain permeability than polyamide 6, which makes polyamide 6,6 perfect for carpet.2The most notable characteristic of both polyamide 6 and 6,6 is now versatility. Although originally developed as an “artificial silk,” it has been used for a vast variety of applications. Polyamide fibres are used for garments, sheer hosiery, parachute cloth, backpackers' tents, bridal veils, musical strings, rope, broom and tooth brush bristles, Velcro and many other applications.3<br/>Polyamide 6 and 6,6 blend well with other fibres, and their chief contributions are strength and abrasion resistance.1Polyamide 6 and 6,6 are machine washable, dry quickly, need little pressing, and holds shape well since they neither shrinks nor stretches, thereby minimizing water and energy use associated with consumer care and washing.4Due to refer their durability and abrasion resistance, some Polyamide 6 and 6,6 products have the potential to polyamide fibers last and be worn many times, optimizing the energy and resources embodied in generalthe product.
The most common polyamide is ''polyamide 66'' (Polyamide), whose starting monomers, adipic acid and hexamethylene diamine. A similar variant is prepared by adding the reaction of caprolactam and the result is called ''polyamide 6'' or ''perlon''. There are a variety of polyamides with varying numbers of carbon atoms of monomers. The usual polyamide fibers are produced by melt spinning processes with additives of matting agents, optical brightening agents and catalysts. Later versions of the polyamides are the so-called [[aramids]]. These are made of aromatic diacids and diamines. They have very high melting points and therefore cannot be melted by spinning processes. They must be spun from solutions. The fiber class [[aramids]] include [[Nomex]] are often used in firefighter’s uniforms, and [[Kevlar]]. Kevlar has, in addition to [[flame retardant materials]], also reinforcing properties and is used instead of fiberglass where light weight is a requirement.== Potential impacts ==
