Does Viscose Shrink in the Dryer? The Truth About Viscose Fabric and Drying
Yes, viscose is highly prone to shrinking in the dryer. Avoid high heat whenever possible to preserve the size and shape of your viscose garments.
Understanding Viscose: A Beginner’s Guide
Viscose, also known as rayon, is a semi-synthetic fabric made from wood pulp or other plant-based materials. While celebrated for its silky texture, drape, and breathability, understanding its behavior in the laundry, especially in relation to heat, is crucial for maintaining its quality. This guide delves into the nuances of viscose, specifically addressing its tendency to shrink when exposed to the dryer’s intense heat.
The Properties of Viscose and Why It Matters
Viscose fibers are inherently weaker when wet, making them susceptible to damage and distortion during washing and drying. The manufacturing process involves breaking down plant cellulose and reconstituting it into fibers. This process, while efficient in creating a soft and versatile material, results in fibers that lack the inherent stability of natural fibers like cotton or linen. This instability is compounded by heat.
Here’s a breakdown of some key properties:
- Absorbent: Viscose absorbs moisture readily, more so than cotton.
- Weak When Wet: This makes the fabric more prone to stretching and damage.
- Drapeable: It has a beautiful drape, making it ideal for clothing.
- Breathable: Viscose is comfortable to wear, especially in warmer climates.
- Prone to Wrinkling: It wrinkles easily and needs careful ironing.
- Potential to Shrink: High heat exacerbates shrinking, especially in the dryer.
Does Viscose Shrink in the Dryer? The Science Behind the Shrinkage
The intense heat of a dryer causes the viscose fibers to contract and tighten, leading to significant shrinkage. The extent of shrinkage depends on several factors, including the dryer’s temperature setting, the fabric’s weave, and whether the garment has been pre-shrunk. Generally, viscose can shrink by as much as 3-5% or more, which can significantly alter the fit of your clothing.
Safe Drying Alternatives: Avoiding the Dryer Altogether
The best way to prevent viscose from shrinking is to avoid using the dryer altogether. Opting for air-drying is much safer. Consider these alternatives:
- Air-Dry: Lay the garment flat on a clean, dry surface or hang it on a padded hanger away from direct sunlight.
- Towel Dry: Roll the wet garment in a clean, dry towel to remove excess moisture before air-drying.
- Low Heat (if necessary): If you must use a dryer, use the lowest heat setting possible and check frequently.
Common Mistakes: Actions That Worsen Viscose Shrinkage
Several common laundry mistakes can worsen viscose shrinkage. Avoid these pitfalls:
- Using High Heat: As mentioned, this is the biggest culprit.
- Over-Drying: Leaving clothes in the dryer for too long, even on low heat, can cause shrinkage.
- Aggressive Washing: Harsh washing cycles can weaken the fibers, making them more susceptible to shrinkage.
- Ignoring the Care Label: Always read and follow the manufacturer’s instructions.
Identifying Viscose: How to Be Sure You’re Dealing with It
Viscose is often labeled as “rayon,” but sometimes it can be disguised under brand names. Check the garment’s care label. If it lists rayon or viscose, exercise caution when washing and drying. Also, be aware of blended fabrics. A blend containing viscose will also require a gentler approach to laundering.
Troubleshooting Shrinkage: Is There Anything You Can Do?
Unfortunately, reversing viscose shrinkage is often difficult, if not impossible. While some suggest soaking the garment in lukewarm water and gently stretching it while wet, the results are usually limited. Prevention is key.
Frequently Asked Questions (FAQs)
What is Viscose Made Of?
Viscose is manufactured from regenerated cellulose fiber. The cellulose typically comes from wood pulp, bamboo, or other plant-based sources. The plant material is broken down and reformed into fibers.
How Much Does Viscose Shrink in the Dryer on Average?
Viscose can shrink anywhere from 3-5% when exposed to high heat in the dryer. This percentage can be even higher depending on the fabric weave and how aggressively it’s dried.
Is Air Drying the Only Safe Option for Viscose?
While air drying is the safest option, using a dryer on a very low heat setting may be acceptable, provided you check the garment frequently and remove it while it’s still slightly damp.
Can I Iron Viscose to Prevent Shrinkage?
Ironing won’t prevent shrinkage, but it can help smooth out wrinkles. Use a low to medium heat setting and iron the garment inside out.
What is the Best Way to Wash Viscose?
Wash viscose garments in cold water on a delicate cycle. Avoid harsh detergents and bleach. A gentle fabric softener can help prevent static cling.
My Viscose Garment Shrank! Can I Unshrink It?
Unshrinking viscose is difficult. Some suggest soaking it in lukewarm water and gently stretching it while wet, but results are often minimal. Prevention is always the best approach.
Is Viscose the Same as Rayon?
Viscose is a type of rayon. The terms are often used interchangeably. However, other types of rayon, like modal and lyocell, have different properties.
Why is Viscose So Popular If It Shrinks Easily?
Despite its tendency to shrink, viscose remains popular due to its softness, drape, and breathability. It’s also a relatively inexpensive fabric, making it an attractive option for clothing manufacturers.
Can Dry Cleaning Prevent Viscose Shrinkage?
Dry cleaning is often a safer option for viscose garments, as it avoids water and heat. However, always check the care label to ensure dry cleaning is recommended.
Does Viscose Shrink More After the First Wash?
The most significant shrinkage typically occurs during the first wash. However, repeated washing and drying can continue to cause gradual shrinkage over time.
Does the Viscose Fabric Blend Matter When Drying?
Yes, a blend of viscose with other fabrics like polyester or cotton may be more resistant to shrinkage than 100% viscose. However, it’s still best to err on the side of caution and avoid high heat. Always consider the most delicate fiber in the blend when determining how to care for your garment.
What Dryer Settings Should I Avoid for Viscose?
Avoid high heat, normal, and permanent press dryer settings. Opt for the air dry or delicate setting if your dryer has one. If not, use the lowest heat setting available and check the garment frequently. The less heat, the better when dealing with viscose.
