Natural vs. Synthetic Fibers: Classification, Qualities and Life Cycle

The benefits of investing in natural fibers

 

Regardless of sector — agriculture, apparel or manufacturing — fiber facts matter to stakeholders and consumers. Knowing more about cotton and all other fiber varieties is a key building block for informed decision-making.

 

As with all fibers, cotton fiber quality comes in a wide range depending on where and how it’s grown, and how it’s harvested.

 

 

 

 

Cotton fiber is particularly well-suited for apparel and home end uses because of its strength, durability, comfort and temperature resistance. And, in contrast to synthetic, man-made fibers, natural fibers occur in and are sourced directly from nature. For example, cotton is a natural vegetable fiber obtained from the seed of the cotton plant and produced on the plant in bolls. Here are a few of the biggest differences between natural and synthetic fibers and why they matter.

 

The difference between natural and synthetic fibers:

 

  • Natural fibers occur in fiber form in nature as opposed to synthetic fibers which are manufactured.
  • Natural fibers are cellulose-based, protein-based or mineral-based. Because cotton comes from a plant, it is cellulose-based.
  • Some manmade fibers are cellulose-based. Rayon raw cellulose, for example, is sourced from cotton, wood pulp, various grasses and bamboo. Unlike wholly natural fiber, though, these cellulose-based end fibers have been chemically altered from their natural state to produce the new, manmade fiber.
  • Synthetic polymer-based fibers are made from chemical polymers not found in nature and, unlike natural fibers, are mainly insoluble (do not break down in water). Some of these include nylon, acrylic, spandex and polyester.

 

 

 

 

Why choose natural? Whereas manufactured fibers are manmade using materials like glass, metal and plastic, natural fibers are processed and prepared for market without the use of any environmentally destructive synthetic filler fibers.

 

Choosing natural makes a difference when it comes to a product’s end-of-life. Cotton fiber breaks down significantly more quickly in nature than man-made fibers. More importantly, rather than just breaking up into smaller pieces that get spread out across the earth and ocean, natural fibers actually degrade, diminishing the total mass of materials left on the planet after the product loses its usefulness. Ultimately, this means less material in landfills and fewer microplastics in the ocean.
