Wool and Cashmere?

Many people are surprised to learn that cashmere actually comes from a goat native to the high mountains of central Asia. Traders historically referred to this animal as a Kashmir goat, and presumably this is how the “cashmere” name originated. Why is cashmere so expensive? Each cashmere-producing goat can only supply 3-5 oz per year! Besides being extremely soft, high-grade cashmere can be up to 8x as warm per weight as regular sheep’s wool. If you see cashmere pieces that have prices that seem too good to be true, beware. There are multiple grades of cashmere yarn. Besides buying your cashmere from a trusted brand, check the label to see if other materials have been added. Pure cashmere is labeled as dry-clean only for a reason. Although special detergents exist to hand-wash cashmere at home, dry cleaning is the most reliable way to clean this luxurious, expensive type of wool.

What’s Merino Wool?

Merino wool is named after the Merino sheep, which originated in the highlands of Spain and Portugal. These days, New Zealand produces a significant amount of the world’s merino wool. Merino is simply a sub-type of “regular” wool, and it’s known for being durable and soft. Just like with cashmere, however, it’s important to carefully check the source and label of your merino products. There are also multiple “grades” of merino and it is often blended with synthetic materials or other types of natural fiber (including cashmere). Although merino blends are popularly advertised as being easy to care for, extend the life of these garments by hand-washing in cold water and air-drying flat. Washing merino blends in the machine with warm water and/or throwing in the dryer can cause shrinkage and fabric damage, even in merino blends. For expensive or bigger items, dry cleaning is the best way to make sure the fabric lasts.

Does wool have to be dry cleaned?

Although some wool blends have labels that indicate they can be machine-washed, hand-washing or dry cleaning is the best way to prolong the life of wool-containing garments! For cashmere, you should most definitely dry clean. Some merino or regular wool blends can be gently hand-washed and air-dried away from direct sunlight.

Wool coats, sweaters, and other large pieces are often expensive. Make sure you spot-treat any small stains or spills immediately! As we’ve said throughout this article, the life of expensive investment pieces can be significantly extended by immediately treating stains, dry-cleaning when soiled, and making sure that all items are completely clean before putting away for the season.
