The processing mechanism, structure and property of multiple filament interlaced yarns with alternate tangling and opening parts are described on the basis of experimental data. The most important factor in the interlacing process is an air flow in a yarn duct of an interlacer. The high speed turbulent air jetting into the yarn duct from an air jet nozzle opens multiple filaments of running yarns separately and changes their relative positions. An opening part is formed at the position subjected to the air jet directly and tangling parts are formed at its both ends. The tangling parts keep their forms by the friction among filaments although the tangling part formed before the air jet nozzle is directly subjected to the air jet. Filaments in the tangling parts contact with each another and the number of tangles depends on the processing conditions of the working air pressure and feed ratio.
