Cascade 128 is 100% Superwash Merino Wool
Some helpful tips when washing Cascade 128 Superwash:
Cascade 128 Superwash wool is designed to be machine washable and dryable, making it great for easy care and, by that fact alone, it’s not the same as regular wool. Though it is “easy-care” there are still things that you need to be careful of and watch out for when washing it. Make sure you are following the washing instructions on the ball band for that yarn.
Use ample water.
Friction is the enemy of any natural fiber, especially merino. A lot of energy efficient washers use low levels of water. Large projects need ample water to allow the piece to swish and not rub up against itself repeatedly, causing undue friction. A mesh bag is also helpful in preventing friction.
Use the right soap.
Superwash yarn is safe for the washing machine, but not necessarily for all of the chemicals found in regular laundry detergent. Many laundry detergents contain enzymes to attack protein based stains. Wool is a protein based fiber, which means the enzymes in your detergent can harm the wool. Instead of a conventional detergent we recommend using a soap that is specifically designed for use on wool. Most local yarn shops carry some type of soap appropriate for use on wool.
Use the dryer.
Superwash yarn has been processed to remove the scales on the fibers. These naturally present scales are responsible for the adhering of the fibers during felting. Without the scales the fibers lose their gripping properties. When yarn is wet, it becomes heavy and in the case of Superwash wool it will stretch if given the opportunity. Superwash wool springs back into shape in the dryer. We strongly recommend that you tumble dry your projects to prevent overstretching.
