Do you remember when you first stepped into the world of superwash and non-superwash yarn? I can certainly recall my own initiation. It was an intriguing and perplexing time, to say the least. The mystery surrounding the difference between the two was like a tightly knotted skein of yarn, complex and challenging to unravel. Then, unfortunately, I learned the difference in a rather itchy way. My initial creation, an infinity scarf crafted from non-superwash wool, led to quite an uncomfortable rash. Thankfully, I managed to alleviate the itchiness by treating the fabric with vinegar - just one of many tricks up my sleeve that I'll share on another day. That's when the stark contrast between superwash and non-superwash yarn became crystal clear to me.
Yes, non-superwash yarn can present some challenges, but its uniqueness lies in its distinctive attributes compared to superwash yarn. The crux of the matter between superwash and non-superwash yarn lies in the wool's processing method. So, come, let me help untangle this intriguing conundrum of yarn types and guide you through this fascinating world of wool.

Wool fiber is covered by cuticle scales. Very long cells build the inner structure of the fiber.
SUPER-WASH VS. NON-SUPER-WASH
Superwash yarn is a special kind of wool yarn that has been treated or processed in a way that allows it to be machine washable. Normally, wool fibers have tiny, microscopic scales on them. When these scales come into contact with heat, water, and agitation (like in a typical washing machine), they hook onto each other and cause the wool to shrink and felt. Superwash yarn is treated to remove or smooth down these scales, preventing the felting effect when the wool is washed.
Non-superwash yarn refers to wool that hasn't been treated to make it machine washable. This is the most natural state of the wool fiber, and it retains all of its original characteristics therefore it will felt or shrink if not washed carefully by hand. It has a natural texture and appearance, as the scales on the fibers provide a slight “grip” when the yarn is knit or crocheted.

SUPERWASH YARN
How is Superwash yarn treated?
There are two primary ways this is accomplished:
Coating: The wool is coated with a thin resin or plastic layer covering the scales. This keeps the scales from catching on each other, preventing felting.
Descaling: The wool is exposed to chlorine gas or a strong acid bath that erodes the scales, effectively removing them. Sometimes the wool is coated with a layer of a polymer or resin to smooth it out and add some durability.

Mechanism of felting shrinkage of wool
Superwash yarn can be very convenient for items that need to be washed frequently or for people who prefer machine washing to hand washing. However, making superwash yarn can be chemically intensive and has environmental implications. Moreover, superwash yarn behaves a little differently than regular yarn—it may not be as warm, may not take up the dye, and can lose some of its natural bounce or elasticity.
PROS:
Easy Care: Superwash yarn is machine washable and dryable, making it low-maintenance and convenient for items that will be frequently washed.
Softness: Removing the scales from the fibers can result in a smoother, softer texture.
Hypoallergenic: Removing the scales can also reduce the chance of itching or scratching, making it a good option for those with sensitive skin.
Durability: Superwash wool is more resistant to shrinkage and felting, making it a durable choice for long-lasting items.
CONS:
Loss of Characteristics: Removing the scales can strip the yarn of its natural texture and grip, making it less suitable for certain projects, such as textured or cable patterns.
Loss of Stitch Definition: Superwash yarn tends to produce a more “blended” appearance, which can be less suitable for projects requiring clear stitch definition.
Stretches and loses elasticity:
Less Environmentally Friendly: Making superwash yarn is often more chemically intensive, which can have negative environmental impacts.
Cost: Superwash yarn is often more expensive than non-superwash yarn due to the additional processing required to remove the scales.
"Can you put Superwash yarn in the washing machine and the dryer?”
This is a question I get often, and the answer is….Yes! Superwash yarn is designed to be machine washed and dried. It is treated during manufacturing to prevent shrinkage and felting, making it a convenient and low-maintenance option for crochet projects. However, it’s always recommended to check the care instructions on the yarn label for the specific recommendations for your Superwash yarn, as some may have different washing and drying instructions. For example, some Superwash yarn may require a gentle cycle or a cool temperature setting, while others may recommend laying flat to dry. Note: Always refer to the care instructions on the yarn label for specific recommendations for your yarn.

NON-SUPERWASH YARN
How is Non-Superwash yarn treated? Non-superwash yarn is the most natural state of wool fiber, and it retains all of its original characteristics because it hasn't been treated. No other process is needed after plying the wool besides dyeing, although this is an option as you can also leave the work in its natural color. Non-superwash wool retains the natural characteristics of wool. It's warm, breathable, and has a certain amount of water resistance. It also has a good amount of elasticity, making it easier to crochet or knit. However, because it hasn't been treated to smooth or remove the microscopic scales on the wool fibers, it's not machine washable and must be washed by hand to prevent felting.

"Can you put Non-superwash yarn in the washing machine and the dryer?”
Putting Non-Superwash yarn in the washing machine or the dryer is not recommended. Non-Superwash yarn is not treated during the manufacturing process to prevent shrinkage and felting, so it is more likely to shrink or felt if it is machine washed and dried. Instead, it is recommended to hand wash Non-Superwash yarn in cool water with a gentle detergent and lay it flat to dry. If you want to machine wash a project made from Non-Superwash yarn, you may consider making a gauge swatch first to test its behavior in the washing machine. Always check the care instructions on the yarn label for the specific recommendations for your Non-Superwash yarn.
Conclusion Both types of yarn possess unique characteristics and are suitable for various projects. Thus, the choice between the two often boils down to personal preference and the specific requirements of the project at hand. I highly recommend following a gauge if you plan to work with Superwash or non-superwash wool. Block it, then put it through the washing machine and dryer. This process will allow you to test the yarn in hand and understand its behavior toward such changes. It will also help you determine the yarn required for your project.
Remember, every thread you hold has the potential to be transformed into a masterpiece. The choice is yours, and the possibilities are endless. Be bold in your experiments, test your creativity, and embrace the journey. Each project is a step toward mastery. Your talent, patience, and dedication will bring your visions to life. Embrace the joy of creating, stitch by stitch, and let every piece you make be a testament to your passion. Every skein of yarn is an invitation to a new adventure. Go forth and weave wonders!
