When the width is more than 0.378 mm, it becomes difficult to sufficiently wrap the hologram yarn as a core yarn in the spinning twisted composite yarn, and when the width is less than 0.15 mm, the slit is used. At times, troubles are likely to occur, and problems such as yarn breakage tend to occur during spinning.

As the core yarn, the above-mentioned hologram yarn (plain yarn) may be used as it is. In terms of hologram yarns and other long fibers (filaments),
Another short fiber yarn (spun yarn) may be twisted or pre-twisted beforehand. This twisting may be performed by winding a hologram yarn around another fiber (filament or spun yarn) or by twisting the hologram yarn with another fiber. (Filament or spun yarn) may be wound. Preferable is a hologram yarn wound around a filament of a synthetic fiber such as a polyamide fiber or a regenerated fiber such as a rayon yarn or a Bemberg yarn, or a lined up, and more preferably, a transparent type filament of the synthetic fiber is wound around the hologram yarn. Or aligned.

The spinning composite twisted yarn according to the present invention, characterized in that a hologram yarn obtained by slitting a laminate comprising at least a substrate and a hologram surface is used as a core yarn and a short fiber group is used as a sheath yarn. In the spinning process, short fibers such as cotton yarn, regenerated cellulose fibers, hemp yarns, cellulose acetate fibers, etc., and short fibers such as wool, acrylic fibers, silk, etc. Obtained by twisting together with the core yarn. Of these staple fibers, cotton yarns, regenerated cellulose fibers, hemp yarns, cellulose acetate-based fibers, and the like, which are mainly composed of one type of fibrous fibers, are easily applied to opal processing, and are preferably applied because they have excellent touch. Is done. The fineness of the finished spun twisted composite yarn is not particularly limited, but a fineness of 40 counts or less, more preferably a fine count of 30 counts or less, is preferable from the viewpoint of feel.

The above-mentioned spinning and twisting composite yarn is used alone for knitted fabrics such as knitted fabrics and plain weaves, and is also used as a cross-knitted fabric with cotton yarns and other fibers.
