Nylon 6

Nylon 6 or polycaprolactam is a polymer developed to reproduce the properties of nylon 6,6 without violating the patent on its production.It is a semi crystalline polyamide. Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers. Its competition with nylon 6,6 and the example it set have also shaped the economics of the synthetic fiber industry.



  • Nylon 6 fibres are tough

  • possessing high tensile strength, as well as elasticity and lustre

  • wrinkle proof

  • highly resistant to abrasion and chemicals such as acids and alkalis.

  • The fibres can absorb up to 2.4% of water, although this lowers tensile strength. The glass transition temperature of Nylon 6 is 47 °C.

  • As a synthetic fiber, Nylon 6 is generally white but can be dyed to in a solution bath prior to production for different color results. Its tenacity is between 6 and 8.5 gm/den with a density of 1.14 gm/cc. Its melting point is at 215 °C and can protect heat up to 150 °C on average



  • Gears, fittings, and bearings

  • In automotive industry for underthehood parts

  • Material for power tools housings.

  • Nylon 6 is used as thread in bristles for toothbrushes, surgical sutures, and strings for acoustic and classical musical instruments, including guitars, sitars, violins, violas, and cellos.

  • In Manufacturing a large variety of threads, ropes, filaments, nets, and tire cords, as well as hosiery and knitted garments
