Polyamide Fiber | Physical And Chemical Properties Of Nylon 6

Nylon 6

Nylon 6 is an important polyamide. Moreover, it is a synthetic fiber. In fact, it is produced by the polymerization of the different organic complexes. The production flow chart of nylon 6 will be described in one of the next blogs. Significantly, nylon 6 is a strong fiber and it is used to carry out various types of heavy tasks like nylon 6.6. Generally, the color of the nylon 6 is white but it could be colorful by adding different dyes in the solution bath before fiber production.

Textile fiber consists of some characteristics. Like other synthetic fibers, nylon 6 also has some physical and chemical properties.

Physical Properties of Nylon 6:

There are some physical properties of nylon 6. The following are the physical properties of nylon 6. They are-

  1. Tenacity: 6.0 – 8.5 gm/den
  2. Density:  1.14 gm/c.c
  3. Elongation at break: 15 – 45%
  4. Elasticity: Very good
  5. Moisture Regain (MR%): 3.5 – 5%
  6. Resiliency: Good
  7. Melting point: 2150C
  8. Ability to protest friction: Excellent
  9. Color: White
  10. Light reflection ability: Not good.
  11. Ability to protect heat: Up to 1500C
  12. Lusture: Bright to light

Chemical Properties of Nylon 6:

Nylon 6 has some chemical properties. The following are the chemical properties of nylon 6. They are-

  1. Acids: Like nylon 6.6, nylon 6 has not enough ability against acidic action.
  2. Basic: Basic does not cause harm to the nylon 6. Nylon 6 has enough ability against alkali.
  3. Effect of bleaching: Strong oxidizing agent is harmful for the nylon 6.
  4. Organic solvent: It becomes soluble in any dense acid or phenol.
  5. Protection ability against mildew: Mildew cannot cause harm to the nylon 6.
  6. Protection ability against insects: Insects cause harm to the nylon 6.
  7. Dyes: Nylon 6 could be dye by Direct dyes, Acid dyes and vat dyes.

So, that’s all about the physical and chemical properties of nylon 6. I think this will help you to identify nylon 6 from other synthetic fibers.

  1. We are a general Trading company, involving into a fishing nets business.
    we would like to inquire for the following colors:
    _ Terasil Yellow 83
    _ Terasil Blue 23
    _ Erionyl Black MR
    _ Erionyl Navy Blue %180
    We would like to use it for Polyamide 6.
    We also wanted to have colors for Polyester & Fibers.
    If you had recommendation for any other colors that we can use please let us know.

  2. It would really help if you cited the credible sources of your information please.
    This would have been great for my assignment on polycaprolactam (nylon 6) but I can’t cite this for academic purposes.
