- a known entanglement nozzle can be used as the entanglement nozzle used as the processing apparatus 29.
- the entanglement nozzle has a guide hole 51 through which the thread is passed and air communicating with the guide hole 51. It is provided with a duct 53.
- the air duct 53 is connected to an external blower such as a blower and is tapered at least on the side of the guide hole 51, so that a relatively high-speed air flow A4 is blown into the guide hole 51. Has been done.
- the airflow A4 ejected into the guide hole 51 produces a relatively high speed turbulence at its outlet, which entangles the threads passing through the guide hole 51.
- the entanglement nozzle may be provided with a water nozzle that applies a small amount of water to the threads, or the water nozzle may be installed upstream of the entanglement nozzle.
- Thread 10 is obtained.
- the design thread 10 is taken over by the winder 31.
- a known interlaced nozzle may be used instead of the entangled nozzle described above, or a false twisting device such as a hollow spindle or a combination of a friction type twisting device and a heating device may be used.
- an actual twisting device may be used instead of these false twisting devices.
- the actual twisting device is, for example, a combination of a twister and a spindle.
- the spindle can also serve as a winder. According to the actual twist, the decorative fibers 5c are more tightly entwined in the threads 1 and 3, and the threads 1 and 3 are more firmly focused.
- heating or bonding may be used.
- the heating means include a heater, a laser, and an ultrasonic generator.
- the design thread 10 has a relatively long fluff-like structure due to the decorative fiber 5c cut short. Although each structure is fluffy, it does not easily fall off as fluff because it is tightly entwined with the threads 1 and 3.
- the size of the structure can be freely changed by the length of cutting the decorative thread, and the distance between adjacent structures can be freely changed by the interval of cutting the decorative thread. Needless to say, the size and spacing can be changed for each structure. Further, as already described, since two or more decorative threads can be used, for example, different colors can be used for each structure.
- the decorative fiber 5c is inserted at the exact position where the threads 1 and the threads 3 are intertwined with each other with respect to the threads 1 and 3 that merge while swirling. Therefore, it is possible to prevent the decorative fiber 5c from being entangled exactly at a desired position or falling off without being entangled.
