What Fabrics Shrink Easily in the Wash?

Knowing which materials are prone to shrinkage can help you take the right steps to care for your clothes.

In this article, we’ll identify fabrics that are most likely to shrink and share tips on how to prevent it.

Understanding Shrinkage

Fabric shrinkage can occur if fibers are exposed to heat and moisture.

The shrinkage can be further exacerbated by the tumbling action during washing and drying, which softens and compresses the fibers, forcing them closer together.

Fabrics Prone to Shrinking

Not all materials shrink at the same rate when washed and dried.

For example, some fabrics are more susceptible to shrinkage than others, especially those made from natural fibers.

Common examples include:

• Cotton
• Wool
• Silk
• Linen
• Rayon/viscose

Cotton

Cotton is one of the most common fabrics found in our wardrobes, but it’s also one of the most prone to shrinking.

The porous structure of the fibers mean they tend to shrink when exposed to heat and friction. This is due to the fibers becoming tangled and twisted, which leads to a reduction in size.

To prevent your favorite cotton t-shirt from turning into a crop top, it’s best to wash it in cold water and air dry it whenever possible. This will reduce the risk of the fibers contracting and help maintain the garment’s regular size.

From casual cotton t-shirts to delicate items made from cotton fibers, appropriate precautions will help maintain the freshness and fit of your garments.

Wool

Wool’s crimped fibers can shrink significantly when exposed to heat and moisture, leading to a process known as felting.

Felting occurs when the fibers of animal hair, such as wool, clump together, creating a dense and compact fabric. This can drastically reduce the size of your garments.

To avoid your wool sweater from downsizing to doll dimensions, make sure to handle it carefully. that means handwashing in cool water using a gentle detergent and letting them air dry completely.

Never use the dryer as the heat will damage the delicate fibers.

Silk

Silk is renowned for its luxurious feel and delicate nature, but it is also highly sensitive to heat and friction, which can cause it to shrink.

Given that, it should always be hand washed in cold water and air dried.

Using harsh detergents or washing silk in hot water can lead to unwanted shrinkage and can damage the fabric’s smooth texture.

Linen

Linen fibers are less elastic, making them more susceptible to shrinking.

To keep your linen garments looking their best, it’s best to wash them in cool water and air dry them. That will help maintain their original size and prevent the fibers from contracting.

Rayon/Viscose

Rayon, also known as viscose, is a fabric that mimics natural fibers but is highly prone to shrinking in hot water and high temperatures.

Like natural fibers, rayon/viscose fibers can undergo structural changes due to heat and friction, which can result in significant shrinkage.

To prevent that, it’s best to hand wash rayon/viscose in cool water before letting it air dry.

Synthetic Fabrics and Shrinkage

Compared to natural fibers, synthetic fabrics like polyester, nylon, and acrylic are generally less prone to shrinkage.

Having said that, they can still shrink when exposed to high heat during washing or drying.

The quality of the synthetic fabric can also influence its likelihood of shrinking, with lower quality fabrics being more prone to fiber shrinkage.

Polyester

To prevent polyester from shrinking, we recommend washing it in cold water and air drying it. Using low heat settings can also help maintain the fabric’s size and shape.

Nylon

To maintain the shape and longevity of nylon fabrics, it is best to use low-heat settings for both washing and drying.

Acrylic

To avoid shrinkage, it is important to dry acrylic on low heat settings and avoid over-drying. That will not only help maintain the fabric’s size but will also prevent static build-up.

Mixed Fabrics and Their Behavior

Mixed fabrics often offer the best of both worlds, combining the durability of synthetics with the comfort of natural fibers.

However, their shrinkage characteristics can vary based on the specific blend and the dominant fiber. Some common mixed fabrics include other fabrics such as:

• Cotton-polyester blend
• Wool-acrylic blend
• Silk-rayon blend
• Linen-viscose blend

Cotton-Polyester Blends

Cotton-polyester blends generally shrink less compared to pure cotton but still require careful washing to prevent damage.

To prevent shrinkage, it is best to wash cotton-polyester blends in cold water and avoid high heat settings during drying.

Wool-Synthetic Blends

Wool-synthetic blends, such as wool-polyester, offer the comfort of wool with added durability and reduced shrinkage benefits of synthetic fibers.

However, these blends still require gentle handling to maintain the delicate wool fibers.

To prevent shrinkage, wash wool-synthetic blends on a delicate or wool setting using cool water and mild detergent. Air drying is also recommended.

Other Blends

Silk-synthetic blends retain the luxurious feel of silk while gaining improved durability from the synthetic fibers. Similarly, linen-cotton blends combine the breathability of linen with the softness of cotton, offering comfort and reduced wrinkling.

For these blends, washing in cool water and air drying is best. That will help maintain their original size and prevent the fibers from contracting.

Techniques to Prevent Fabric Shrinkage

By following these tips, you can greatly reduce the risk of your clothes shrinking:

1. Read care labels carefully before washing
2. Use cold water instead of hot water
3. Air dry your clothes instead of using a dryer
4. Choose the right washing and drying cycles for your fabrics

Reading Care Labels

Care labels provide vital instructions on washing and drying that are specific to the fabric type.

For example, care labels will often specify the recommended washing temperature and whether hand washing or machine washing is preferred.

Using Cold Water

Cold water will help preserve the ‘off-the-rack’ size of clothes by reducing fiber contraction. This is especially true for natural materials like cotton and wool, which are prone to shrinkage in hot water.

Air Drying

Air drying is a safe and effective method if you want to prevent shrinkage, especially for delicate materials.

By avoiding the high heat of a dryer, you’ll be able to maintain the size and integrity of your garments. This is particularly important for fabrics like wool-synthetic blends and rayon/viscose, which are prone to shrinking in high temperatures.

To air dry effectively, lay your clothes flat on a clean surface or hang them up, ensuring they are properly supported to prevent stretching or warping.

Choosing the Right Cycle

Choosing the right cycle for washing and drying is also crucial. Here are some guidelines:

• Delicate cycles are best as they reduce agitation and stress on the fabric, helping to maintain its integrity
• Cotton-polyester blends benefit from cold water and gentle cycles
• Wool-synthetic blends should be washed on delicate or wool settings

Using low heat settings and avoiding heavy-duty cycles can also help prevent deformation and shrinkage in fabrics like nylon and silk-synthetic blends.

Can Shrunken Clothes Be Restored?

If you end up with shrunken clothes, there’s no need to panic. There are ways to restore them to their original size.

For example, soaking and stretching may relax the fibers, making it possible to reshape the garment. In some cases, however, professional help may be necessary to effectively restore delicate or valuable items.

Soaking and Stretching

A lukewarm water soak with hair conditioner or baby shampoo can help relax the fibers of shrunken clothes, allowing them to return to their prior size.

For example, soaking a cotton item in warm water with hair conditioner for about five minutes can do wonders if your clothes shrink.

After soaking, gently pull and massage the fabric to reshape it. Rolling the garment in a towel to remove excess water before stretching will also help with the reshaping process.

Understanding Why Fabric Shrinks In the Wash

Knowing which fabrics are prone to shrinking and taking the appropriate care measures can save you from the frustration of shrunken clothes.

Natural fibers like cotton, wool, silk, and linen are more susceptible to shrinkage compared to synthetic fibers. By following care labels, using cold water, air drying, and selecting the right washing and drying cycles, you can significantly reduce the risk of shrinkage.
