Physical And Chemical Properties Of Polypropylene Fiber

Polypropylene Fiber

Polypropylene is a 100% synthetic textile fiber. It is basically formed by about 85% propylene. Besides, the monomer of polypropylene is propylene and propylene is a by-product of petroleum. It is cheap in price than polyester. It is also used as an alternative to plastic. Hence, this polypropylene is harmful to the environment. It is not degraded with soil, so it causes harm to the soil. Also, it is not decomposed by water for this reason it is used as the rope of a ship. Its moisture regain is too much less which is negligible to count.

Polypropylene Fiber

Now, I like to present the physical and chemical properties of polypropylene.

Physical Properties of Polypropylene:

Polypropylene is a strong fiber. The following are the physical properties of polypropylene. They are-

  1. Tenacity:  3.5 – 8.0 gm/den
  2. Density:  0.91 gm/c.c
  3. Elongation at break: 10 – 45%
  4. Elasticity: Very good
  5. Moisture Regain (MR%): 0%
  6. Resiliency: Good
  7. Melting point: 1700C
  8. Ability to protest friction: Excellent
  9. Color: White
  10. Ability to protest heat: Moderate
  11. Luster: Bright to light

Chemical Properties of Polypropylene:

The following are the chemical properties of polypropylene. They are-

  1. Acids: Acid does not affect polypropylene. It has excellent protesting ability against acids.
  2. Basic: Basic does not affect basic.
  3. Effect of bleaching: It has enough ability to prevent the harmful action of bleaching agents under 65oC.
  4. Organic solvent: Organic solvent does not cause harm to polypropylene during the action.
  5. Protection ability against light: It loses energy from sunlight.
  6. Protection ability against mildew: Good
  7. Protection ability against insects: It does not affects by insects.
  8. Dyes: Difficult to dye polypropylene because its moisture regain is 0%. But pigment dyeing is possible.

So, polypropylene is a harmful product to the environment. Although it has some application in some special cases we should ignore it for our environmental safe.

  2. Polypropylene yarn is NOT harmful for the environment:

    1. It is mass dyed (no water is polluted during its production as compared with thousands of liters when producing one kilogram of cotton, the colours are permanently anchored in polypropylene yarn and do not subside into your skin)
    2. You dont use any pesticides to produce polypropylene yarn
    3. Polypropylene yarn is 100% recyclable
    4. To produce polypropylene yarn and to produce textiles from polypropylene yarn you need lower temperatures, so less energy

    Polypropylene yarn is an ENVIRONMENTALLY FRIENDLY yarn.

    Polypropylene yarn has the quickest moisture transport and doesnt absorb moisture. That is why its best to be used in sports clothes.
