Steam-setting is a process in the twisting production that uses hot steam to set the twist of the yarn. During the process of converting raw materials into yarn, internal stresses become unbalanced due to repeated forces and friction, leading to deformation. This causes fatigue and static electricity; additionally, the yarn, after twisting, has a high untwisting torque, which will affect the progress of subsequent production processes.

A process for stabilizing yarn twist under hot and humid conditions. After yarn twist is set, it prevents tangles and loops during relaxation, thereby avoiding defects such as weft shrinkage in fabrics.

After twisting, the fibers in the yarn experience tensile stress, leading to internal resistance against further twisting, which destabilizes the yarn twist. Increasing temperature or moisture content can weaken the intermolecular forces between the fiber macromolecules, causing the fibers to relax and eliminate the internal stress opposing twisting, thereby achieving stability in the yarn twist.
