The process of conferring stability of form upon fibres, yarns, or fabrics, usually by means of successive heating and cooling in moist or dry conditions.
Note : The term is sometimes used in conjunction with a description of the particular characteristics to be stabilized (e.g., twist setting, crimp setting) or of the setting medium (e.g., heat setting, steam setting).
