What is Merino Wool?

Well, it’s not wool! Merino wool is derived from merino sheep, which tend to be smaller animals than the ones used for traditional wool. This means that their meat products are also small, and this doesn’t leave much wool. But where there’s a need, there’s a way.  

Merino was first introduced in Australia in 1797 when the first wave of merino sheep was imported from South Africa and Tasmania. From here on out, merinos became a staple of Australian farming, and the product derived from them became known as “merino” in comparison to “wool” which comes from an older breed. Australia was the first to use merino wool commercially. Today, it’s very popular, used in woolen and blended yarns.

Merino is very fine wool because of its high Merino Wool Shrink Test fibers. But guess what? This is exactly what makes it shrink. Merinos’ very fine fibers make them more prone to wrinkles compared to traditional woolen sheep. If you’ve ever tried on a shirt and it seemed to hang on your frame when you moved, this would be because there were wrinkles caused by the merinos’ fibers pulling into the fabric from your movements.

Why Does Merino Wool Shrink?

Washing Your Merino Clothes Properly

The first thing you want to do when washing your merino cloth is washed it by itself. It doesn’t matter if there’s any detergent in the fabric. The best way to know if your clothes shrank is to try them on, and that’s what you’ll be doing when you wash your clothing.

If they fit, you’re set! But what if they don’t? If the clothing shrinks too much and doesn’t fit, it’s because the length of the fibers has changed. In this case, a little bit of water-based detergent can help so that the fabric will soak up some of the soap’s surfactants and help evenly distribute it to other parts of the cloth. This will also help with any shrinkage in width as well since there will be a lot less surface area for water to attack.

How to Tell If Your Merino Wool is Shrunken?

Now you’re wondering how you’re going to tell if your merino clothing has shrunk. While it may seem like it’s impossible to tell whether or not the wool has shrunk, there’s a simple way. 

A small piece of masking tape can be applied and then removed. When the tape is removed, it will have left behind some sticky residue that you can roll between your fingers. If the wool doesn’t seem to have shrunk at all, you’re good to go. If it shrinks a little, you can use the second piece of tape and try again.

If the pattern on your clothing seems a bit different (or if your sweater hangs differently than before), then you’ll need to wash it again and try again. Once you’ve washed it again, you can use more tape to help determine whether or not the wool has shrunk.

But even with all this tape and experimenting, it’s still hard to tell whether or not the wool has shrunk. And you don’t have to. A simple way to determine whether the percentages of fibers are the same is called the Merino Wool Shrink Test. This test uses a piece of fabric of your choice (usually an old pair of pajamas), and then you measure how much the wool shrinks when it’s stretched. To do this, mark your fabric with a permanent marker at the end of the fabric before you stretch it. When you measure how many shrinks, you’ll be able to determine whether or not the fibers shrink in length or width.

Matching the Number of Fibers in Your Clothing to the Shrinkage Merino wool shrinkage is dependent on the length of fibers, so if you notice that your clothing shrinks and also has shorter fibers, then chances are it shrank in length. If you notice that your piece of wool has wider fibers and it shrank wide or short, chances are it shrank in width.

How to Maintain Your Clothing When they’ve shrunk After they’ve shrunk, the next step is an easy one. You can launder them in the same way that you would any other wool clothing. If you’re concerned that the piece of clothing will shrink again, simply buy it a little bit longer than you would like it to be.

Essentially, merino wool is woven from very fine fibers, which results in a unique shrinkage pattern. For example, it’s common for merino wool to shrink lengthwise but not widthwise. This makes it great for sweaters as you can buy your skinnies a bit too long and they’ll shrink just enough to be the perfect length!

How Much Does Merino Wool Shrink?

Wool naturally shrinks more when it’s wet. This is because it absorbs a lot of water, and this is also the main reason why the wool fabric is usually dry cleaned rather than washed by machine. For this reason, most people aren’t expecting wool garments to have shrunk in the first place.

This means that according to your expectations, you might never see merino wool shrink. But every wool, in general, will easily shrink if you wash or pull it forcefully or with hot water.

If you think about it, it’s made from sheepskin. Sheepskin is the fur of the animal (in this case a sheep) and wool is the body hair of the animal. When you wash merino wool, do you still remember that bit of water on your palm? It’s no different from any other fabric materials you buy.

Temperature

The hotter your washing machine water is, the more shrinkage you get. If you’re lucky enough, only machines with cold water are available to use in your home, and this gives less chance for shrinkage to happen.
