Does Viscose Fabric Shrink? (All You Need to Know)

The choice of fabric plays a significant role in the durability and maintenance of your garments. Viscose fabric (rayon), a semi-synthetic fiber made from trees, has gained popularity in the fashion industry due to its softness, breathability, and versatility. But does viscose fabric shrink in the wash?

Yes, viscose fabric can shrink when in the wash. However, the percentage of shrinkage will vary depending on the water temperatures and ratio of the viscose in a blended material. Read on to learn more on viscose fabric shrinking before doing your next laundry.

Does Viscose Fabric Shrink?

Viscose fabric has the potential to shrink when exposed to certain conditions, water, or heat. Since it tends to absorb moisture, it can swell and shrink when it comes into contact with water. However, the extent of shrinkage varies based on factors like the fabric's quality, water temperatures, the specific manufacturing processes used, and maintenance.

Why Does Viscose Shrink?

Viscose fabric shrinks when exposed to certain conditions due to its composition. However, viscose fabric tends to shrink less than natural fabrics like silk and cotton. Here are the main factors that contribute to the shrinkage of viscose fabric:

1. Cellulose component

Cellulose can absorb and release moisture. Therefore, viscose fabric picks up the same characteristic component. As a result, this moisture absorption can cause the fabric to shrink when exposed to water.

2. Natural elasticity

Unlike other fabrics, such as cotton or wool, viscose lacks natural elasticity. This means that when the fabric absorbs moisture, it cannot stretch and return to its original shape, resulting in shrinkage.

3. Manufacturing process

The production of viscose fabric involves several steps. The fabric may experience tension, stretching, or compression during these processes, affecting its dimensional stability.

4. Absorption of moisture:

Viscose has a high moisture regain property; it can absorb and hold moisture from the surrounding environment. When exposed to water, such as during washing, the fabric fibers can swell and contract as they absorb and release moisture, leading to shrinkage.

5. Water temperature

Higher water temperatures, such as 40 degrees, can accelerate the swelling and contraction of the fabric fibers, leading to greater shrinkage. Therefore, it is advisable to use cold water when washing viscose fabric.

Types of Viscose Fabric

Several types of viscose fabric are available, each with its unique characteristics. The varieties include:

1. Viscose Rayon

Like cotton, viscose rayon is a versatile and comfortable fabric perfect for making various garments and household items. It is a lightweight, breathable material that can easily be dyed or printed with patterns or designs.

2. Viscose Modal

This viscose rayon fabric has undergone different processes to make it even softer and more durable. Due to its pleasant and absorbent qualities, it is an excellent choice for inner pants or casual clothing.

3. High wet modulus viscose

It is a type of viscose fabric carefully treated to increase durability and shrinking resistance. It is used for a variety of products, including clothing.

4. Viscose Cupro

Viscose Cupro is a fabric made from cotton linter, a byproduct of the cotton industry. Its texture is silky and smooth and is often used to make luxury clothing and lingerie.

5. Viscose Bamboo

It is a natural eco-friendly alternative to other types of viscose fabric. It is made from bamboo pulp which is a renewable resource. It is soft and breathable, making it ideal for clothing and bedding.

How to Unshrink Viscose Fabric?

It can be challenging to reverse a shrunken viscose fabric completely, but you can try the following methods to relax and restore the fabric potentially:

1. Soaking in lukewarm water

Fill up your basin or sink with lukewarm water and add a few drops of baby shampoo. Put the shrunken viscose garment inside and let it soak for about 30 minutes to allow the fibers to relax. Remove the garment from the water and spread it out on a clean towel to dry. Stretch it back to its natural form gently.

2. Steam treatment

Hang the shrunken viscose garment in your bathroom while taking a hot shower. The shower's steam might aid in relaxing the fibers. Alternatively, use a handheld steamer to direct steam onto the fabric then gently stretch it to restore its shape. Be cautious not to get the fabric too wet during the steaming process.

3. Fabric stretching

Place the shrunken viscose garment on a flat surface. Pull to stretch the fabric with your hands, or place heavy objects like books on the edges of the fabric to hold it in a stretched position. Leave it in this stretched state for several hours to allow the fibers to regain their original shape.

How Should Viscose Be Washed to Prevent Shrinkage?

To wash viscose and minimize the risk of shrinking, here are some guidelines to follow:

• Check the care instructions: Always check the care label on the garment for specific washing instructions. The manufacturer's recommendations take precedence over general guidelines.
• Hand wash or gentle machine wash: Hand washing is the safest method for viscose, as it allows for better control over the process. If you prefer machine washing, use the gentle cycle with a delicate or hand-wash setting. This helps minimize agitation and reduces the risk of shrinkage.
• Use cold water: Viscose is sensitive to heat, so washing it in cold water is best. Hot water can cause the fibers to shrink and lose their shape.

Note: Avoid warm or hot water, even if the garment label allows it.

• Mild detergent: Harsh detergents can damage viscose fibers and lead to shrinkage. Following the detergent's instructions for the appropriate amount to use is essential.
• Skip the dryer: Avoid using a clothes dryer because heat can make the cloth shrink and lose its form. Alternatively, place the cloth flat on a dry, clean towel or hang it to dry in a well-ventilated area away from direct sunlight.

Conclusion

Viscose fabric shrinks when exposed to certain conditions, such as water and heat. However, it is relatively resistant to shrinkage compared to other natural fabrics. When washing and caring for viscose clothing, it's important to adhere to standard procedures such as; using your hand when washing, using mild detergent, and using cold water. By doing so, you can enjoy this versatile fabric's softness, comfort, and durability.
