What Is Bison Yarn?

Bison yarn(1) is an animal fiber sold at expensive prices.

This fiber isn’t popular because it isn’t widely available, however it’s extremely soft, lightweight, hypoallergenic.

It’s also extremely durable.

They’re non-shrinkable and great for high-quality knits. Softer bison knit yarns have a micron count of 15.

It’s available dyed in a range of different colors.

Where It Comes From

Bison yarn is made from the undercoat of a bison.

Most commonly, this fiber is harvested from the Great Plains region of North America. It’s sometimes grown in Canada.

Many Americans call the Bison a Buffalo.

The coat of a bison (which protects their hides from the wet and cold) is two types of hair.

  • Outer guard hairs
  • A downy undercoat

It’s the crimpy down hair that’s used to make this fiber.

How It’s Made Into Yarn

After the bison is sheared, the undercoat is gathered and cleaned. Once clean, the fiber is carded for spinning.

Carding is untangling and straightening fibers so they can be spun into yarn.

Once the fiber is spun into yarn, it’s ready to be used!

Here is a video interview by Marly Bird for her podcast Yarn Thing on a bison farm and fiber producer.

How To Wash Bison Yarn

Here are the care instructions for bison fibers.

Bison yarn is best hand washed in lukewarm water with a mild soap.

Roll in a towel to remove excess moisture and dry flat. Don’t put it in the dryer, as this damages the fibers.

Always check the yarn label for instructions specific to the yarn you’re using.

Does It Shrink When Washed?

Bison yarn is a non-shrinking and non-felting fiber (2).

This is great news if you’re worried about your garments losing shape or shrinking in the wash.

How To Soften Bison Yarn

Here is a quick and easy method to soften bison yarn.

It’s a soft fiber, but if you find it too rough, soak it in lukewarm water with fabric softener for about 20 minutes.

After that, rinse well and lay flat to dry.

Washing it after you’ve finished knitting always helps!

Common Blends Using This Fiber

Here is a list of common blends using this yarn, and why they’re created.

It’s also sometimes blended with cashmere (5) or silk for a luxuriously soft yarn.
