Does Viscose Shrink?

Viscose is an interesting synthetic material that has great appeal on first impressions. This version of rayon is a great alternative to silk and can feel great against the skin. However, you may have seen people venting online after disastrous laundry experiences. So, does viscose shrink and, if so, can you do anything about it?

Yes viscose does shrink. If you have clothing made from viscose there is a good chance that it will shrink because of its make-up and the properties of the fibers. Therefore, it is important to be as careful as possible when handling this material, especially when it comes to cleaning it. Thankfully, there are things that you can do to avoid shrinkage and you may also be able to correct the problem if your viscose clothes shrink in the wash.

Why is viscose so prone to shrinking?

Viscose is a very delicate material that doesn’t hold up well to much at all. It is not a great material to work with or to use for garments designed for regular wear. The material doesn’t have much in the way of elasticity and is also very absorbent. So, there is the risk that your clothes will end up damaged when wet and when in the washing machine. The risk decreases when you have a fabric that is a blend of viscose and something like cotton. Cotton has a much more minimal risk of shrinking unless you are particularly careless with it on the wrong cycle. People with 100% viscose clothes, on the other hand, have experienced extreme shrinkage up to around 25%, making garments unfit for further use.

Does It Shrink a Lot?

The answer here all depends on your definition of a lot. There are big differences in the shrink percentages highlighted below where one seems pretty reasonable compared to the other. But, a 3% shrink is still noticeable and could affect the fit. If you were to go against all the guidance here regarding caring for this fabric then you would find that it will shrink a lot. If you are careful with the temperature and handling of the garment then shrinkage will be minimal or perhaps even avoidable. Prepare for the worst and you shouldn’t have too many problems.

How Much Does Viscose Shrink?

If you would prefer to see a more definitive percentage of shrinkage then there are estimates you can follow. Some say that you should expect a 3 to 5% shrinkage rate with the wrong conditions. But, there are also reports of 25% lost in the first wash. This probably comes down to the temperature and perhaps other external factors. But, it also shows that you can’t predict this accurately. It is better to plan for the worst and try to avoid these issues as best you can.

Does Viscose Shrink In The Dryer?

Unfortunately, there is a very good chance that clothing made from viscose will shrink if exposed to high heat in a dryer.

Instead, it is best to hang them up to air dry and let the sunshine do all the work. Still, you need to be careful with direct sunlight. Some people put their viscose clothing in the dryer when nearly dry on a cool setting to keep them soft. However, this could depend on your machine and how much you are willing to take that risk.

Therefore, hot water is going to have an even worse effect. The shock of the temperature changes in the water could lead to a big contraction in the fibers and other damage that results in significant changes in the size of your clothes.

How Do You Wash Viscose Without Shrinking It?

You may also decide to use a dryer for a greater chance of success. Be prepared for it to go further than expected or for other damage to occur.

How to Shrink Viscose and Elastane?

Some blends of viscose and other fibers will shrink easier than others. It all depends on the properties of that other leading material. With elastane, you have a fiber that is stretchy and unpredictable like viscose. There is the potential for it to shrink with the right temperature and other treatments. However, there is no way of knowing just how much it will shrink. This isn’t just because of the material but also because of some potential treatments and other factors with store-bought blended clothing. This unpredictability means it is inadvisable to try to deliberately shrink viscose/elastane material that has stretched too much.

How To Shrink Viscose and Polyester

The blend of viscose and polyester is a little bit different. Here you have a material that is a lot more stable because of the strong synthetic polyester fibers. This can be great when it comes to buying and making garments because you have less to worry about in terms of care and durability. You may get less shrinkage or stretching, which in turn makes it more difficult to achieve noticeable results when altering clothing.

Does Viscose Shrink More Than Cotton?

Cotton can shrink a little bit when it isn’t properly cared for because of the absorbancy of the natural fibers and the risk of them contracting in the heat. Viscose performs a lot worse under those conditions and will, therefore, shrink a lot more than cotton does. On average, cotton will shrink at a rate of about 2% in first washes without proper care. That isn’t as bad as the rate above. Some of the worst cases see 20% lost in shrinkage after washing, which is significantly less than the viscose.

How to Unshrink Viscose?

As you can see, there are lots of chances that your viscose fabric will shrink either a little or a lot in the wrong conditions. So, it helps to have an idea of what you can do to try and unshrink the material and restore the fit. The chances of success here aren’t great because of the volatile nature of these fibers. But, there is no harm in trying. So, the best option is to put the material in some water with a fabric softener or hair conditioner. It only needs a few minutes to take in the ingredients. Then stretch the material by hand and hang it up to dry. Hanging on a hanger may allow gravity to play its part here too.

What can you do to minimize the risk of viscose clothing shrinking?

It all comes down to how you wash these clothes. Obviously, you can’t avoid getting them wet forever as they will need to be cleaned when dirty or smelly. So, you need to be careful not to overdo things and to make sure that the water isn’t too hot. The best way to do this is to handwash the clothes in cold water with a little bit of gentle detergent. There may be a hand-washing mode on your machine. However, doing this by hand in a basin gives you greater control over the temperature, the way that the fabric is agitated in the water, and the duration of the wash.

You might find that you have a blended material with care instructions that allow for machine washing. Here it is up to you which method you use. You can go with the instructions on the label and hope that there is no sign of shrinkage afterward. Or, you can continue to play it safe and handwash these items.

Then you need to hang the clothes up to dry somewhere that isn’t too hot. It can be tempting to put them out in the sun to speed up the process but the high heat on the wet material could lead to some shrinkage. Instead, put them somewhere airy but cool enough to avoid this issue. Don’t put the clothes in the dryer as even the lowest setting could prove to be damaging.

Can you reverse viscose shrinking?

Just in case the worst happens here and you have a garment that shrinks in the wash, it helps to be able to correct the problem.

This process works well on other materials so you might regain some shape here too. Soak the fibers in the solution, stretch them as best you can while wet, and then leave the clothing to dry. Unfortunately, if you are unlucky enough to experience extreme shrinkage then you are unlikely to get the garment back to a shape that fits.

Is viscose worth it?

There are plenty of concerns when it comes to handling viscose clothing and the risk of it shrinking considerably. There are even warnings not to go out in wet weather because the rain may damage the fibers and the sun could shrink it when it dries back out. Only go for a 100% viscose piece of clothing if you are confident in caring for it. Otherwise, look for more suitable blends.
