You've just purchased a trendy piece of clothing, but there's a concern: it's made of Rayon fabric, and you're unsure about the consequences of putting it in the washing machine. You are not alone — join us as we examine whether rayon fabric shrinks when exposed to water and heat.

Before putting any piece of clothing in your washing machine, you have to ask yourself one question — will this shrink? This is especially true when it comes to rayon fabric. When it comes to heat and moisture, fabrics can be unpredictable. So, if you don't want to bid farewell to your favourite shirt or dress, knowing how rayon fabric handles these conditions is crucial.

Does Rayon Fabric Shrink?

Absolutely! Rayon can shrink between 5-15% on average, although proper care can mitigate this. The degree of shrinkage can vary depending on the type of blend used with rayon. For instance, cotton-rayon blends tend to shrink more than polyester-rayon ones. Heat is another crucial factor to consider; it's rayon's nemesis. Be sure to avoid washing rayon in excessively hot water - not exceeding 86 degrees - and refrain from drying it on high heat or for prolonged periods。

What Is Rayon Fabric?

Rayon is a popular synthetic fabric used in various applications, from clothing to home furnishings. The fabric has been popular among apparel makers due to its ability to expand and contract easily without losing the general appearance of the fabric. This is great since it allows the fabric to be used in a wide variety of garments and accessories.

Rayon was initially developed using cellulose fiber, which included dissolving and regenerating natural cellulose fibers like cotton and linen. The current process hasn't changed much, though it has been improved to make the fabric more durable, soft, and lightweight. The fibers are woven into the fabric, but rayon is not as stabilized as cotton fabrics. As a result, rayon can shrink to some extent, although not to the same degree as cotton.

Why Does Rayon Fabric Shrink?

Does rayon fabric shrink when exposed to water and heat? Yes, but why? The following are two major reasons why rayon fabric shrinks when exposed to heat and water.

Manufacturing Process

Rayon is a versatile fiber created by blending cotton, wool, or polyester fibers to form a unique textile material. Through a process of vacuum-forming synthetic fibers onto a continuous cellulose acetate base, rayon is produced using heat and pressure. It, therefore, follows that when the fabric is subjected to heat, it shrinks. Basically, during the washing cycle, when subjected to heat, the fabric becomes increasingly rigid and tightens further as it dries.

Detergents and Fabric Softners

Detergents and Fabric Softeners are also known to contribute to the shrinking of rayon fabric. Using excessive detergent can leave behind a residue on your clothes, resulting in stiffness and roughness. Similarly, fabric softener can cause excessive lint accumulation and hinder drying. So, when washing your clothes with rayon fabric, it is important to use the right amount of detergent and fabric softener to avoid shrinkage.

Does Rayon Shrink in The Washing Machine？

If you have a washing machine, you may wonder whether rayon shrinks in the machine. Using a washing machine to wash your rayon fabrics will undoubtedly affect the garment and will make it shrink, particularly if you use hot water or a high-spin cycle. When washed, Rayon fabric tends to soften and requires more time to dry than other fabrics. During the initial wash, rayon may shrink by approximately three to five percent. To ensure your clothing retains its shape, it is important to allow adequate time between washings.

Pro Tip(s):

Before washing your rayon clothing, check the garment tag for instructions indicating whether it has been pre-washed or can be washed with other materials. If either of these conditions is met, it's advisable to wash your rayon clothing separately.

How to Prevent Rayon From Shrinking?

If you don't want your favourite rayon clothes to shrink, you must take precautions. The following are some of the tips to help you avoid rayon shrinkage:

Give Rayon the Spotlight: Keep your rayon clothing separate from other materials when it's time for a wash. This solo treatment will help avoid any unwanted shrinkage surprises.
The Magic of Cleaning: Begin by giving your rayon garment a normal cleaning session. Bid farewell to dirt and stains that may have taken up residence. Then, gather similar items made of comparable materials and wash them together.
Separate the Shrinking Suspects: Unsure which pieces in your laundry load might pull a shrinking trick? Play it safe and separate them from the rest of your garments. Consider adding a dash of vinegar or bleach to tackle any stubborn dirt or stains contributing to further shrinkage.
Flat is the New Cool: After the washing adventure, it's time for the drying stage. Lay your rayon clothes flat to dry like a starfish on a sunny beach. This little trick helps them maintain their shape and avoid any unexpected shrinking surprises.

Does Cold Water Make Rayon Shrink?

Rayon shrinks in hot water, but does it shrink in cold water? No, Rayon should not shrink when washed in cold water. So, if you are looking for a way to ensure without a doubt that your rayon clothes don't shrink, cold water is the answer. If you use a washing machine, try to set the temperature to the coldest possible setting, or just use cold water.

Bottom Line

Yes, rayon fabric shrinks when washed and dried — especially when you use a washing machine. Rayon fabric's Achilles heel lies in its manufacturing process, where heat plays a pivotal role in creating its distinctive appearance and texture.

Therefore, the fabric will shrink whenever subjected to heat and may even get damaged or disfigured. We hope you now better understand whether rayon fabric shrinks and take the necessary precautions to ensure that it doesn't. Don't be afraid to use rayon fabric; just be sure to stay away from heat sources and follow the care instructions when washing and drying.
