Woollen and worsted are two common types of yarn used in the textile industry. The main difference between the two lies in their production process and the characteristics of the resulting yarn.
Woollen yarn is typically made from the shorter fibers of a wool fleece. It undergoes a carding process that disentangles the fibers and aligns them roughly parallel to each other, creating a more textured and bulky yarn. This texture gives woollen yarn its signature loftiness and warmth. The presence of air pockets between the fibers also adds to its insulation capabilities. You will see this type of yarn used in heavier wool garments or inferior quality 'cheaper' products.
Worsted yarn, on the other hand, is made from longer wool fibers that have been combed and aligned in a parallel manner. This combing process removes shorter fibers and any impurities, resulting in a smoother and more tightly twisted yarn. This smoothness gives worsted yarn a more compact and dense structure, leading to a yarn with less elasticity, a sleek finish, and better stitch definition.
Worsted yarn is smoother, denser, and typically more durable. It has less bulk and more drape, making it suitable for garments that require a neater and crisper feel, such as tailored suits, skirts and of course TheMerinoPolo.
