Wool yarn comes in different types, often labeled as Super 100s, 120s, 140s, and so on. These numbers refer to the fineness of the wool fibers used to make the yarn, which is measured in microns. A micron is a unit of measurement that is used to measure the diameter of individual wool fibers.
For example, Super 100s wool is made from fibers that are 18.5 microns in diameter or finer, while Super 200s wool is made from fibers that are 12.5 microns in diameter or finer. This means that Super 200s wool is much finer and softer than Super 100s wool, as its fibers are thinner.
The measurement of wool fibers in microns is important because it affects the quality and feel of the final product. Wool with finer fibers is generally considered to be more luxurious, as it feels softer and smoother against the skin. However, wool with finer fibers can also be more delicate and prone to damage, and may require special care when washing and storing.
Understanding the different types of wool yarn and the micron measurement can help you make more informed choices when selecting wool fabrics for your projects. With this knowledge, you can choose the perfect wool yarn for your needs, whether it's for a cozy sweater or a formal suit, while also considering factors such as durability, maintenance, and price point.
