A process for manufacturing a yarn includes twisting the yarn in a first direction for a predefined number of twists. The method also includes, after the predefined number of twists, twisting the yarn in a second direction for a predefined number of twists, the predefined number of twists for the second yarn is same as the predefined number of twists for the first yarn. The twisting of the yarn in the second direction creates an air bed within the yarn's fibers.

A yarn spinning system has a sliver feeding part feeding a main material used for yarn formation; a main spinning unit in which the spinning procedure of the main materials is performed; suction pipes present in the main spinning unit and enabling the intake of waste fiber formed during spinning; the draft cylinders enabling orderly drawing and smoothing of the main material (fiber) fed into the system; additionally to provide conveying the injected yarns fed into the system to a draft area through the yarn feeding path; and enabling fancy yarn production by conveying the injected yarns to the main spinning unit by being centered on the main material via the yarn guide.

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.
