Wool is a popular fabric for clothing and other items because of its warmth and durability, but it can also be tricky to care for.

  • Does all wool fabric shrink? No, some types of wool are more prone to shrinkage than others.

Reasons Why

There are several reasons why wool fabric can shrink:

  • Natural fibers: Wool is a natural fiber, which means it has the potential to shrink when exposed to water and heat.
  • Heat: High temperatures can cause the fibers in wool to contract and tighten, resulting in shrinkage.
  • Agitation: Rough handling during washing can cause the fibers to mat and shrink.
  • Moisture: Wool absorbs moisture easily, which can cause it to shrink if it’s not dried properly.


To prevent wool fabric from shrinking, here are some tips to follow:

  • Read the care label: Always check the care label on your wool clothing or fabric to see if it’s machine washable or dry clean only.
  • Use cold water: Wash wool in cold water to minimize shrinkage.
  • Avoid agitation: Use a gentle cycle or hand wash to prevent rough handling.
  • Air dry: Hang wool items to dry or lay them flat, rather than using a dryer.

How To

If you’ve accidentally shrunk your wool clothing or fabric, here are some steps you can take to try to unshrink it:

  • Soak in lukewarm water: Fill a sink or basin with lukewarm water and add a small amount of hair conditioner. Soak the wool item for 15-30 minutes.
  • Stretch and reshape: Gently stretch the wool item back to its original shape and size while it’s still damp.
  • Air dry: Lay the wool item flat on a towel and let it air dry.
