Yes, Tencel can shrink when washed, but the extent of shrinkage generally depends on how the fabric is handled during the laundry process. Tencel is known for its durability and moisture management, yet like many natural fibers, it can be prone to shrinkage if not cared for properly.

Here are a few tips to minimize shrinkage when washing Tencel:

1. Wash with Cold Water: Use cold water settings during washing. Hot water can cause natural fibers like Tencel to contract, leading to shrinkage.

2. Gentle Wash Cycle: Select a gentle wash cycle. Harsh washing can stress the fibers and contribute to shrinkage.

3. Air Dry: Whenever possible, air dry Tencel garments and bedding instead of using a tumble dryer. If you must use a dryer, opt for low heat settings and remove the items while they are still slightly damp to reduce the risk of shrinking.

4. Avoid Over-drying: Over-drying Tencel in high heat can lead to significant shrinkage. It's better to under-dry and allow to air dry completely afterward.

By following these care instructions, you can help maintain the shape and size of your Tencel fabric items. Always check the care label on Tencel products for specific instructions from the manufacturer to ensure you are providing the right care.
