Continuous Heatsetting

The process of applying heat to yarns to "set" or retain bulk, twist and spring introduced by spinning and/or twisting. Continuous heatsetting can be applied to staple or continuous filament yarns. The two primary types of continuous heatsetting equipment are the Superba, which uses steam and pressure, and the Suessen, which uses dry heat. (See "Heatsetting.")
