What Is Polyester Yarn?

Polyester yarn is a synthetic fiber sold at moderate prices.

This fiber is popular because it’s durable, easy to care for, soft, and cuddly. They’re lightweight and great for clothing.

It’s available in all colors of the rainbow. It’s often used for making novelty yarn.

Where It Comes From

Polyester is a polymer-based fiber made from petroleum, often compared with acrylic yarn.

This means that it’s not a natural fiber, but it’s recyclable.

How It’s Made Into Yarn

The polyester yarn manufacturing process begins by creating long chain synthetic polymers.

These are melted and drawn through small holes to create thin fibers. These fibers are twisted together to create yarn.

How To Wash Polyester Yarn

Here are the care instructions for polyester fibers.

  • Machine wash on the delicate cycle in cool water
  • Use a mild detergent
  • Don’t use bleach or fabric softener
  • Tumble dry on low or lay flat to dry

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

Does It Shrink When Washed?

Polyester is a synthetic fiber, so it’s less likely to shrink than natural fibers like wool.

That being said, I recommend doing a swatch and washing it before you start your project.

Don’t expose it to heat.

How To Soften Polyester Yarn

Washing it after you’ve finished knitting always helps!

What Do You Use It For?

Wondering whether you should use it to make a project? Here’s why this fiber is used to make yarn.

It’s often used for projects and things like:

  • Baby clothes
  • Toys
  • Blankets
  • Pillows
  • Hats
  • Scarves
  • Clothing

It’s great for things that need frequent washing and drying, like kid’s items and things you’re going to donate.

Also, it doesn’t absorb moisture, so it’s a good choice for making hats and mittens.

They’re wrinkle-resistant and hold their shape well, so they’re a popular material for athletic wear and everyday use.

Polyester novelty yarns are a little tricky to knit with. Use bamboo knitting needles.

The super bulky yarns you can get make excellent crochet or knitted fabrics for chunky a sweater or blanket.

Common Blends Using This Fiber

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

  • Polyester/Cotton – The cotton adds softness, while the polyester adds durability to this composition
  • Polyester/Wool or Merino Wool – The wool adds warmth to this popular blend, while the polyester is durable and easy to care for. It’s also elastic and nice on the skin
  • Polyester/Acrylic – The acrylic adds softness, while the polyester adds durability to this yarn blend

You rarely see it blended with mohair, silk, or alpaca.
