Yes, viscose can shrink. Understanding why and how to prevent it is essential to maintaining the quality and fit of your viscose garments. Here’s a detailed guide to help you manage viscose fabric and prevent unwanted shrinkage.
Understanding Viscose
Viscose, also known as rayon, is a semi-synthetic fiber made from cellulose, usually derived from wood pulp. It’s popular for its silk-like feel, breathability, and drape. However, its natural fibers and manufacturing process make it susceptible to shrinkage under certain conditions.
Why Does Viscose Shrink?
Viscose fibers are sensitive to water and heat, which can lead to shrinkage. Here are the primary reasons why viscose shrinks:
- Water Absorption:
- Viscose is highly absorbent, and the fibers swell when exposed to water. This swelling can cause the fabric to contract and shrink as it dries.
- Heat Exposure:
- High temperatures during washing or drying can cause viscose fibers to contract, resulting in shrinkage. Heat can also damage the fibers, leading to further shrinkage over time.
- Mechanical Agitation:
- The movement and agitation during machine washing can distort viscose fibers, contributing to uneven shrinkage and fabric distortion.
How Much Does Viscose Shrink?
Viscose can shrink significantly if not handled properly, often shrinking up to 5-10% of its original size during the first wash. Pre-washed or pre-shrunk viscose will generally shrink less.
How to Prevent Viscose Shrinkage
To keep your viscose garments in top shape and minimize shrinkage, follow these care instructions:
Washing Tips
- Hand Wash:
- The safest method. Use cold or lukewarm water and a gentle detergent. Gently swish the garment in the water and avoid wringing or twisting.
- Machine Wash:
- If you must use a washing machine, select a delicate cycle with cold water. Place the viscose item in a mesh laundry bag to reduce agitation.
- Avoid Harsh Detergents:
- Use mild, gentle detergents specifically formulated for delicate fabrics to protect the fibers.
Drying Tips
- Air Dry:
- Lay the garment flat on a clean, dry towel, reshaping it to its original form. Avoid hanging viscose as it can stretch out of shape and exacerbate shrinkage.
- Avoid Heat:
- Never use a tumble dryer for viscose. The heat can cause significant shrinkage and damage the fabric.
Ironing and Storage Tips
- Iron While Damp:
- Iron viscose while it’s still slightly damp using a cool iron. This helps to smooth out wrinkles without damaging the fibers.
- Proper Storage:
- Store viscose in a cool, dry place. Avoid cramming it into tight spaces to prevent creasing and fiber stress.
What to Do If Viscose Shrinks
If your viscose garment has already shrunk, you can try to restore it to its original size with these steps:
- Soak in Lukewarm Water:
- Fill a basin with lukewarm water and add a small amount of baby shampoo or hair conditioner. This helps to relax the fibers.
- Gently Stretch:
- After soaking for about 15-20 minutes, gently squeeze out excess water without wringing. Lay the garment on a flat surface and gently stretch it back to its original shape and size.
- Air Dry Flat:
- Allow the garment to air dry flat, reshaping it as necessary.
Conclusion
Yes, viscose can shrink, but with proper care, you can minimize this risk and keep your viscose garments looking fabulous. Here’s a quick recap:
- Hand wash or use delicate machine cycles with cold water.
- Avoid high heat when drying; air dry instead.
- Use a mild detergent.
- Iron while the fabric is damp.
By taking these precautions, you can enjoy the luxurious feel and beautiful drape of viscose fabric without worrying too much about shrinkage. Proper care will ensure your viscose items remain in great condition and retain their shape and size.
