What is Polyamide Fiber made of?



A polyamide is a polymer containing monomers joined by peptide bonds. They can occur both naturally, examples being proteins, such as wool and silk, and can be made artificially, examples being Nylons, Aramids, and sodium poly(aspartate).

Nylon is a thermoplastic silky material, first used commercially in a nylon-bristled toothbrush (1938), followed more famously by women's “nylons” stockings (1940). It is made of repeating units linked by peptide bonds (another name for amide bonds) and is frequently referred to as polyamide (PA). Nylon was the first commercially successful polymer and the first synthetic fiber to be made entirely from coal, water and air. These are formed into monomers of intermediate molecular weight, which are then reacted to form long polymer chains.
Nylon was intended to be a synthetic replacement for silk and substituted for it in many different products after silk became scarce during World War II. It replaced silk in military applications such as parachutes, flak vests, and was used in many types of vehicle tires.

There are plenty of yarn blends out there that may include nylon. Some are fancy, some are more crude, but it is up to us to create beauty out of these yarns. It is a favorite in blends for socks and for making stuff that needs some elasticity. I enjoy 100 % Nylon to make bath stuff, like scrubbers that will sustain the abuse of daily washing . All in all I wanted to share this online , because I did not know that Nylon was polyamide as well and when you see a yarn that is made out of this stuff or that has a percentage of it, you will know what is that polyamide !

This Berroco Bonsai Bamboo yarn has a 3 % nylon thread that keeps the bamboo from fraying. It did not take away from the feeling of bambbo, I believe Berroco went all out into making a great Bamboo/Nylon blend.


Thanks for stopping by.
