Worsted processing

The worsted system is much more fussy on the type of wools that are required. They tend to be finer because the end products are going to be high-quality apparel fabrics that want soft handle and lightness of weight, good breathability and all these other desirable consumer properties. So you’re starting with finer wool. The demands for strength and length are much more critical to get a good, fine, even yarn. The target is fine even yarn, and an uneven yarn means it’s going to have thick and thin places where it may break during processing and also will look less tidy and less attractive. So that’s why we have these extra steps which don’t feature in the woollen system but are vital to making a good worsted yarn.
