energy tube and the filament receiving means ranges from about 15 u00b0 to 75 u00b0 processing the continuous filaments through the chamber produces crimped or textured filaments means are provided for commingling the textured filaments from each of the chambers to form a variable texture yarn a method for production of a variable texture yarn is described a first group of continuous filaments is textured in a first chamber of a multi chamber moving cavity texturing apparatus while a second group of continuous filaments is textured in a second chamber of the same texturing apparatus thermal communication is maintained between the first chamber and the second chamber the geometry of the chambers is selected so as to assure that the difference in the skein shrinkage levels between the first group of textured filaments and the second group of textured filaments differs by at least thirty percent 30 the first group of textured filaments and the second group of textured filaments are commingled fig1 is a schematic representation of a prior art single chamber moving cavity texturing apparatus fig2 is a representation of a section taken along line 2 2 of the apparatus shown in fig1 fig3 is a schematic representation of a dual chamber moving cavity.
