    Abstract: A composite twist yarn is produced by twisting a spun yarn and at least one filament together. The composite twist yarn has features that the twisted direction of the composite twist yarn is substantially identical to the twisted direction of the spun yarn entwined in the composite twist yarn, and that the number of twists of the composite twist yarn is larger than that of the spun yarn entwined in the composite twist yarn. The composite twist yarn is produced by making a twisted spun yarn and at least one filament parallel to each other to a paralleled yarn, twisting the paralleled yarn in a direction reverse to the twisted direction of the spun yarn, and continuing the twisting over an untwisted point of the spun yarn.
