This study deals with the effect of cross-sectional shape of yarn duct of interlacer on the performance of interlaced yarn and aims at finding the interlacers with better performance. The performance of the interlaced yarn is evaluated by the number and strength of tangles. Seven interlacers with different shapes of yarn duct were designed. Each of them has the same cross-sectional area of yarn duct. Experiments were carried out at various supplied air pressures, yarn speeds and feed ratios. We have found that the interlacer with round cross-sectional shape of yarn duct is capable of producing an interlaced yarn with a large number of tangles and the cornered cross-sectional shape is effective in improving the strength of tangles. Among these seven interlacers, the interlacer with an elliptical or an inverse-triangular shape has the best processing performance. And the interlacer with a square cross-sectional shape has the worst processing performance.
