How to identify open end and ring spun yarn?

Open-end yarn can be identified by its unique construction process, where fibers are drawn from a feed and twisted together without the use of a spindle, resulting in a coarser texture and less strength compared to ring-spun yarn. In contrast, ring-spun yarn is made by continuously twisting and thinning the fibers, leading to a finer, smoother, and stronger yarn. Visually, open-end yarn may appear bulkier and less uniform, while ring-spun yarn typically has a more consistent diameter and softer feel. Additionally, ring-spun yarn often exhibits better durability and elasticity.
