In a yarn interlacer appts., shock waves extend completely across the path of yarn travel through the bore, and pref. travel in opposite directions along the bore from a fluid entry duct at about the midpoint of a bore in an interlacer. Specif. the yarn may pass through the bore of a second interlacer, and the fluid entry ducts of each interlacer are either more than, but less than 1.5 times, the bore cross-section, or are at least double the bore cross-section, or are equal to it. The appts. is esp. compacting and interlacing spun cellulose acetate filaments before wind-up and allows processing without producing tie points which show as flashes in fabrics.
