PURPOSE: To obtain conjugated interlaced yarn capable of readily providing a conjugated structure having the difference of yarn lengths, sufficiently keeping characteristics of conjugated yarn even in a post-process and capable of manifesting these characteristics and excellent also in process passing properties.
CONSTITUTION: This conjugated interlaced yarn is combined interlaced yarn consisting of two or more multifilament yarns and alternately having an interlaced part and a combined part. In the combined and interlaced yarns, the difference in the lengths between the longest yarn and the shortest yarn is ≥20% and interlacing number N (number/m), a ratio of the interlaced part length NL to the opening part length OL and number of opened part in every loop height and true twist number T (T/m) satisfy the following formulas (1) to (4), respectively: (1) 30≤N≤100; (2) 0.5≤OL/NL≤1.5; (3) Oh1>Oh2>Oh3 and 60≤[Oh1/(Oh1+Oh2+Oh3)]×100, with the proviso that Oh1 is number (number/m) of opened part having a loop height of ≥0.5mm and <1.0mm; Oh2 is number (number/m) of opened part having a loop height of ≥1.0mm and <1.5mm; Oh3 is number (number/m) of opened part having a loop height of ≥1.5mm and (4) 10≤T≤50.
