A composite interlaced yarn is a filament subjected to an interlacing process, wherein the filament is a multifilament, and the composite interlaced yarn includes a plurality of continuous circulation units in a longitudinal length; each circulation unit includes a splitting part I, an interlacing part I, a splitting part II and an interlacing part II connected in sequence; an interlacing fastness of the interlacing part I is different from an interlacing fastness of the interlacing part II. An interlacing method for the composite interlaced yarn includes: the multifilament that is not subjected to the interlacing process sequentially adjusting a pre-tension by a tensioner, passing through a yarn path of a jet, and winding by a winding roller, so as to obtain the composite interlaced yarn, wherein a jet hole I and a jet hole II are formed in the jet.

Composite interlaced yarn, interlacing method and application therefor

A one-step spun composite DTY and preparation method thereof are provided. The bi-profiled fiber is manufactured with two types of modified polyester of different viscosities through the steps of melting, melt metering, composite extruding, cooling, oiling, drawing, heat setting and winding. Wherein those two modified polyesters have a molecular structure including terephthalic acid segments, ethylene glycol segments and branched diol segments, and the branched diol has a structural formula of
