A polyamide manufactured from aliphatic monomers is commonly designated as nylon. The structural units of a polyamide are joined together by an amide, -NH-CO-, group. Nylon 6 is a synthetic polyamide fiber which is synthesizes from a monomer called caprolactam.

Physical Properties:

Chemical properties:

Effect of acids: It is damaged by strong acids.

Effect of bases: It is resistant to bases. Nylon 6 melts in boiling dimethyl formamide (DMF).

Ability towards microorganisms: It is resistant to microorganisms, moths.

Effect of organic acids: It is resistant to organic acids. It becomes soluble in any dense acid or phenol.

Effect of bleaching: Strong oxidizing agents damages the nylon 6.

Effect of inorganic acids: It is resistant to inorganic acids.

Dyes: it could be dyed with vat, acid and direct dyes.
