Cost- and Performance-Effective Zytel® PA Polyamide Nylon

Dec 23,  · Both, polyamide (often called by its most famous brand name: nylon) and polyester are polymers. This means that their fibers are made of a long chain, made of molecules linked to each other. In polyamides, these molecules are linked together by .

Both synthetic fibres are very tear-proof and abrasion-resistant and absorb little moisture (thus good transport of moisture away from the body) and are stretchy, crease-free, but also prone to pilling.

Amide groups have the general chemical formula CO-NH. They may be produced by the interaction of an amine NH 2 group and a carboxyl CO 2 H group, or they may be formed by the polymerization of amino acids or amino-acid derivatives whose molecules contain both amino and carboxyl groups.

Broadly defined, the polyamides include proteins and peptides , which are naturally produced polymers consisting of amino-acid repeating units. In molecular biology the amide linkage is usually referred to as the peptide bond. More narrowly defined, the polyamides are an important group of industrially produced synthetic polymers. The most important is nylon , actually an extremely versatile class of polymers that are made into indispensable fibres and plastics. Another class of polyamides made into fibres is the so-called aramids , or aromatic polyamides—amide polymers that contain phenyl rings in their repeating units.

Some nylons also contain phenyl rings, so the two classes are actually distinguished by the number and frequency of the rings. When 85 percent or more of the amide groups are linked directly to phenyl rings, the polyamide is classified as an aramid.

When the rate is lower than 85 percent, the polymer is classified as a nylon. We welcome suggested improvements to any of our articles.

Polyamides can also be synthesized from dinitriles using acid catalysis via an application of the Ritter reaction. This method is applicable for preparation of nylon 1,6 from adiponitrile, formaldehyde and water. Additionally, polyamides can be synthesized from glycols and dinitriles using this method as well.
