Plastic-based fiber

Otherwise known as "synthetics".

BAD FOR THE PLANET and You.

As we researched more about plastic-based fibers, we learned they were not only far less sustainable than natural fibers, but they also performed far worse. Compared to the protein-based fibers we use in our sweaters, khullu and merino, plastic-based fibers are poor thermoregulators and trap odor.

a closer look...

Plastic-based materials are made by forcing crude-oil-based plastic polymers through tiny holes to create a thread, which is twisted into a yarn used to make clothing. Plastic-based materials such as polyester, nylon, acrylic, spandex, and lycra make up 60% of the world's production of yarn fiber.

Allergies & Durability:

Unlike natural materials, like khullu and merino, plastic-based fibers are chemically produced and are an allergen to some.

Plastic-based fibers are highly elastic and durable (they are made from plastic afterall), which makes them much easier to care for than natural fibers. Unfortunately, their durability is a double edge sword. It can take up to 200 years for plastic-based fibers to biodegrade into the earth, so those polyester clothes you have could've been worn by Abraham Lincoln!

Thermoregulation & Breathability: 

Plastic-based fibers underperform in almost every category.

One important distinction is they don't have the same "crimp" as protein-based fibers, meaning they don't insulate or breath efficiently, making them poor temperature regulators.

However, they are ideal for water resistance, which again is a bit of a double edge sword... plastic-based fibers have a molecular structure that doesn't allow for the efficient transfer of sweat away from the skin and into the air as water vapor.

By trapping sweat, plastic-based fibers create an ideal environment for bacteria and thus odor to thrive.

Sustainability:

Compared to natural fibers plastic-based fibers are far less sustainable, consuming 342 million barrels of oil and releasing 380 million pounds of plastic into the ocean every year.
