What Is Wool Yarn?

Wool yarn is an animal fiber sold at moderate prices. This fiber is popular because it’s warm, easy care, durable and insulating, even when it’s wet! They’re easy to find and great for many knitted creations. It’s available in a range of colors.

Where It Comes From

Wool yarn is derived from sheep. Other animals produce wool fiber but here I discuss sheep wool. The hair closest to the skin is called “wool”, while the coarser outer layer is known as “hair”. There are many types of wool yarn, depending on the breed and how the wool is processed.

How It’s Made Into Yarn

After the wool is shorn from the sheep, it’s combed to get rid of any short fibers, dirt, grass or other debris. After this the raw wool is washed, rinsed and spun (nearly dry) and then left to air dry on racks. This is called “scouring”

The next step is to spin the fibers into yarn. Here is a video tutorial by The Woolmark Company on the process of wool production. 

The information in this video on processing wool will be a great help!

It’s spun, either by machine or hand. The wool yarn you’ll find in stores is typically machine-spun. Here is a video tutorial by Chandi from ExpressionFiberArts on how to spin wool yarn on a wheel by hand. 

Spinning is a real art, so much to co-ordinate!

How To Wash Wool Yarn

Here are the care instructions for wool fibers.

  • Use cool water and a mild detergent, like baby shampoo or wool wash
  • Gently agitate the garment in the water
  • Rinse well and press out excess water
  • Lay flat to dry away from direct sunlight

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

Can You Bleach Or Iron Wool Yarn?

No, you should never bleach or iron wool yarn. The heat from an iron shrinks and damage the fibers, and bleaching strips the yarn of its color.

Does It Shrink When Washed?

Yes, wool yarn can shrink when it’s washed or dried on high heat. Always hand wash your garments in cool water.

How To Soften Wool Yarn
