about 90 u00b0 and about 120 u00b0 with reference to the longitudinal axes of the passageways for instance the longitudinal axes interlacers 32 and 33 of fig4 are oriented in an approximately 90 u00b0 angle presently it is considered most preferable if the yarn enters and leaves each interlacer at an angle of about 45 u00b0 for a total yarn angle of 180 u00b0 from feed port 34 to exit port 45 in the variation of fig4 in the variation of fig5 showing three interlacers the longitudinal axis of the yarn passageway of each interlacer perferably remains about 90 u00b0 as illustrated the yarn enters and leaves each interlacer perferably at an angle of about 45 u00b0 for a total yarn angle of about 180 u00b0 i e the yarn reverses the direction of travel in going through the apparatus a further variation on the second embodiment of the present invention concerns the provision of an additional mechanism for concurrently drawing orienting and bulking crimping the yarn this modification is exemplified in example 2 advantageously by combining the drawing and bulking steps with entangling the product yarn is more economical to make previously processes which similarly combined steps were very limited by the speed at which effective entangling and blending of the multicolored filaments could be insured furthermore the combination of this variation with air obviates expensive messy and dangerous steam one manner of carrying out this modification is illustrated in fig6 for the following description reference is made to u s pat no 4 894 894 which has previously been incorporated by reference for the streak potential test taught therein and which is now hereby incorporated by reference for the process and apparatus taught therein.
