Which term describes a kink in an inner yarn that forces the yarns to the surface?

Explanation:
A kink inside the inner yarn that pushes the surrounding yarns up to the surface is called cockle or hockle. When the core or inner yarn develops a kink, it disrupts the lay of the rest of the strands, causing a bulge or ridge to form on the surface of the rope or fabric. This defect is distinct from a simple twist, which is the overall helically wound arrangement, and from bloom, which refers to surface fuzz or fiber protrusion not specifically caused by an inner kink. Cockle or hockle precisely describes that internal kink manifesting as surface irregularity.
