Wool is a beautiful, natural fiber that can last for many years. However, sometimes it can shrink. Did you accidentally throw your favorite sweater in the washer and dryer, only to have it come out several sizes too small? It’s a common problem, but there are ways to fix it. In this article, we’ll provide you with a step-by-step guide on how to shrink wool without damaging it.
Before you begin, it’s important to test a small area of the wool to make sure it doesn’t react badly to the shrinking process. Once you’ve done this, you can gather your supplies. You’ll need: a sink or bathtub, lukewarm water, laundry detergent, fabric softener, and a towel.
Next, fill your sink or bathtub with lukewarm water. Add a small amount of laundry detergent and fabric softener. Stir the water until the detergent and fabric softener are dissolved. Then, submerge the wool item in the water. Gently agitate the item for a few minutes, making sure that it’s completely saturated with water. Allow the item to soak in the water for 15-20 minutes.
Understanding Wool and Shrinkage Behavior
Wool Fiber Structure and Characteristics
Wool, a natural fiber obtained from sheep or other animals, possesses unique structural and behavioral properties that influence its shrinkage characteristics.
Wool fibers consist primarily of keratin, a protein composed of amino acid chains. The amino acid arrangement forms disulfide bonds, creating a cross-linked network that contributes to wool’s strength and resilience.
Within the wool fiber, there are three layers: the cuticle (outer layer), the cortex (middle layer), and the medulla (inner layer). The cuticle, made up of overlapping scales, serves as a protective barrier against external factors.
Wool fibers exhibit a natural crimp or waviness, which increases their elasticity and insulation capabilities. This crimp helps to trap air, providing warmth and cushioning. The extent of crimp varies between different wool breeds and affects the overall texture and appearance of the fabric.
| Wool Fiber Property | Description |
|---|---|
| Keratin Content | Main structural protein, contributing to strength and durability |
| Disulfide Bonds | Cross-links that enhance fiber strength and resilience |
| Cuticle | Outer layer of overlapping scales, providing protection |
| Cortex | Middle layer, responsible for fiber strength and elasticity |
| Medulla | Inner layer, exhibiting a hollow or cellular structure |
| Wool Type | Recommended Tumble Dryer Setting |
|---|---|
| Merino Wool | Low heat, delicate cycle |
| Cashmere Wool | Very low heat, delicate cycle |
| Lambswool | Low heat, delicate cycle |
Air Drying Wool: The Gentle and Time-Tested Approach
Lay Out the Wool Garment Flat
Spread the wool garment on a flat surface, ensuring it is evenly distributed. Avoid hanging the garment as this can cause the fabric to stretch and deform.
Roll Up the Garment
Carefully roll up the garment, starting from one end and tightly wrapping it around a cylindrical object, such as a dowel or cardboard tube. Secure the roll with rubber bands or string.
Place the Roll in a Warm, Dry Environment
Place the rolled-up garment in a warm and dry location, such as near a heater or in a sunny spot. Avoid using a direct heat source, as this can damage the wool.
Check the Fabric Periodically
Unroll the garment every few hours to check the progress of the shrinking. Do not leave it unattended for extended periods, as over-shrinking can occur.
Unroll and Flatten the Garment
Once the desired level of shrinkage is achieved, unroll the garment and lay it flat to dry completely. This will help prevent the fabric from wrinkling or stretching.
Stretch the Garment Gently
Once the garment is dry, gently stretch it to the desired shape and dimensions. This will help set the fabric and prevent it from shrinking further.
Additional Tips
- Test a small section of the garment before shrinking the entire piece.
- Use a damp cloth to dampen the garment before rolling.
- If the garment is particularly thick, roll it up multiple times.
- Avoid using hot water or steam, as this can cause felting.
Using Heat Treatment to Shrink Wool
1. Choose the wool type: Not all wool types shrink evenly. Choose superwash wool, which is treated to resist shrinkage, or regular wool for more significant shrinkage.
2. Prepare the wool: Wash and dry the wool according to the manufacturer’s instructions to remove any oils or finishes.
3. Determine shrink rate: Create a small swatch of the wool by knitting or crocheting a few inches. Wash and dry the swatch to determine the shrink rate, which will vary depending on the wool type and heat treatment.
4. Wet the wool: If using a washing machine, submerge the wool in hot water (180-212°F / 82-100°C). For hand-washing, use a sink or bucket with hot water.
5. Agitate gently: Use a gentle cycle for washing machines, or agitate the wool manually in hot water.
6. Rinse with cold water: Rinse the wool thoroughly with cold water to stop the shrinking process.
7. Blocking for Even Shrinkage:
a. Pin out the wool: Spread out the wool on a flat surface and pin it into the desired shape and size.
b. Apply heat and moisture: Use a steam iron or steamer to apply heat to the wool, moistening it with a spray bottle as needed.
c. Maintain tension: Keep the wool pinned and under gentle tension while applying heat to ensure uniform shrinkage.
d. Cool and dry: Allow the wool to cool and dry completely before removing the pins.
Preventing Accidental Wool Shrinkage
To prevent wool from shrinking, it is crucial to follow these guidelines:
- Check the label: Always read the care label on wool garments to determine the recommended washing and drying instructions.
- Use cold water: Wash wool in cold water only, as hot water can cause the fibers to shrink.
- Hand wash gently: If possible, hand wash wool items. Avoid using an agitator or wringer that can cause felting.
- Use a mild detergent: Choose a detergent specifically designed for wool, as harsh detergents can damage the fibers.
- Avoid chlorine bleach: Chlorine bleach should never be used on wool, as it can weaken the fibers.
- Dry flat: After washing, lay wool items flat to dry. Do not hang them, as the weight of the water can stretch the fibers.
- Never tumble dry: The heat of a tumble dryer can shrink wool significantly.
Reversing Accidental Wool Shrinkage
If you have accidentally shrunk a wool garment, there are a few methods you can try to reverse the shrinkage:
Using Hair Conditioner
Materials needed:
| Item | Quantity |
|---|---|
| Hair conditioner | 1/4 cup |
| Cold water | 1 gallon |
Instructions:
- Fill a large basin with cold water.
- Add the hair conditioner to the water and mix well.
- Submerge the shrunken wool garment in the solution and gently knead for 10-15 minutes.
- Rinse thoroughly with cold water.
- Wrap the garment in a towel to absorb excess water.
- Lay flat to dry, reshaping it as needed.
