Does viscose shrink? Viscose, also known as rayon, is a popular fabric loved for its silky feel, drape, and breathability. Understanding why viscose shrinks is the first step to preventing it. This guide will walk you through everything you need to know to keep your viscose garments looking beautiful and size-perfect for years.
Does Viscose Shrink? Short Answer
Yes, viscose does shrink, often significantly.
Why Viscose Shrinks?
Viscose begins as cellulose from plants. It is transformed into a supple fiber. This process gives viscose a deep thirst for water. The fibers act like tiny sponges. They swell dramatically when wet.
Applying heat during drying forces these swollen fibers to contract quickly. They tighten in a frantic, uneven way. This is the moment shrinkage happens. The fiber possesses little natural resilience. It cannot bounce back to its original form after such stress.
How Much Does Viscose Shrink?
The amount of shrinkage isn’t a fixed number. Shrinkage can range from 3% to 15% or more, depending on several factors:
- The Weave: Loosely woven fabrics shrink more than tightly woven ones.
- Blend: Is it 100% viscose? Or is it mixed with polyester, cotton, or spandex? Blends usually shrink less.
- Care Methods: The biggest factor is how you wash and dry it. High heat is the primary culprit.
A study on fabric care noted that viscose subjected to a standard warm wash and tumble dry could shrink up to 10% in the first wash alone. This is a dramatic change that can ruin the fit of a garment.

How to Prevent Viscose from Shrinking?
1. Become a Label Detective
The care label holds essential guidance. It is your primary source of truth. Manufacturers provide specific instructions there. Your first action is always to read it.
2. Hand Wash: The Safest Method
Hand washing in cool water offers the greatest safety. Fill a basin with water. Choose a mild, gentle detergent. Submerge the item and move it softly through the water. A few minutes are enough. Never twist or scrub the material. Such agitation harms the delicate fibers.
3. If You Must Machine Wash
Some labels permit machine washing. Follow these rules without exception. Set the machine to a cold water temperature. Use a delicate or hand wash cycle. Place the viscose item inside a protective mesh bag. Wash it only with other gentle items. Heavy fabrics cause friction and damage.
4. The Critical Drying Stage
Drying demands your full attention. Heat is the primary enemy. After washing, press water out gently. Never wring the fabric. Lay the garment flat on a clean, dry towel. Reshape it to its original dimensions. Allow it to air dry in this position. Hanging viscose risks stretching it. The weight of water pulls the fibers down. Machine drying typically guarantees shrinkage and should be avoided.
5. Ironing with Care
Iron viscose only when necessary. Ensure the garment remains slightly damp. Select the lowest heat setting on your iron. Place a thin cotton cloth between the iron and the fabric. This barrier prevents scorching and unwanted shine.
Can You Fix Shrunken Viscose?
Step-by-Step Recovery Method:
Prepare a basin of lukewarm water. Add a generous amount of hair conditioner. Soak the garment for twenty minutes. The conditioner relaxes the tightened fibers. Rinse the item carefully. Press out water without twisting. Lay it flat on a thick towel. Slowly, gently, stretch the fabric back toward its proper shape. Focus on the seams and overall length. Use rust-proof pins to secure the shape on a flat surface. Let it dry completely. The fibers may retain this corrected form.
Viscose Blends and Shrinkage
Many modern fabrics combine fibers. These blends offer more forgiveness. Viscose mixed with polyester gains stability. The synthetic polyester resists shrinkage. Viscose woven with spandex gains elasticity. It recovers its shape more readily. Always care for a blend according to its most delicate component. The care label remains your trusted guide.

FAQ
Does viscose shrink in dryer?
Yes. Viscose has a natural tendency to shrink during drying. To maintain size and shape, always air dry flat; the heat and tumbling of a mechanical dryer will cause it to shrink significantly.
Is viscose a natural fiber?
Viscose is a semi-synthetic fiber. It is made from regenerated cellulose, sourced from natural wood pulp, but heavily processed with chemicals. Therefore, it is not considered a truly natural fiber like cotton or wool.
What material is viscose?
Viscose is a semi-synthetic fabric made from regenerated cellulose from wood pulp. It undergoes extensive chemical processing to become the soft, silk-like fiber used in clothing and textiles.
Is viscose a good material?
Viscose has benefits like softness, breathability, and a silk-like drape, making it comfortable. However, it can be delicate when wet, prone to wrinkling, and its environmental impact varies widely based on production practices.
How to measure viscosity?
Viscosity is measured using a viscometer. Common types include rotational (measures torque on a spindle) and capillary (times fluid flow through a tube). Units are Pascal-seconds (Pa·s) or centipoise (cP).
Is bamboo viscose toxic?
Bamboo viscose fabric is generally non-toxic for wearers. The main concern is its production, which heavily uses chemicals like carbon disulfide. This causes significant environmental and worker safety issues, not direct toxicity in the final fabric.
How to wash viscose?
Hand wash in cool water with a mild detergent or use the delicate machine cycle. Never wring it out; gently press water out. Air dry flat, and iron on a low setting while slightly damp to prevent damage.
What type of fabric is viscose?
Viscose is a semi-synthetic, regenerated cellulose fiber. It is made from natural wood pulp but processed with chemicals to create a soft, drapable fabric often used as a silk alternative.
Can viscose be washed?
Yes, but carefully. Hand wash or use the delicate machine cycle with cool water and mild detergent. Never wring it out; air dry flat. Always check the specific garment’s care label first.
What does viscose feel like?
Viscose typically feels soft, smooth, and cool to the touch with a fluid, silky drape. It’s breathable and lightweight, often compared to cotton or silk, but can feel slightly heavier and more fluid than cotton.
Can you iron viscose?
Yes, but with care. Iron while the fabric is still slightly damp, using a low heat setting (silk/wool). Place a thin cloth between the iron and the garment to prevent shine or scorching.
Is viscose environmentally friendly?
It’s complex. Viscose is biodegradable and from trees, but conventional production uses toxic chemicals and contributes to deforestation.
Is viscose better than polyester?
It depends on priorities. Viscose is more breathable, biodegradable, and has a nicer drape. Polyester is more durable, wrinkle-resistant, and dries faster. Environmentally, both have significant downsides in production.
