PROBLEM TO BE SOLVED: To provide a method for producing a fiber having microcapsules stuck thereto which are less prone to fall off, at a low cost. SOLUTION: This production of a fiber having microcapsules stuck to the surface comprises discharging a microcapsule dispersion liquid by using a nozzle device installed with a liquid discharge hole 8 leading to a liquid flow path 5 different from a polymer flow path in the vicinity of each polymer discharge hole 9, bringing the microcapsule dispersion liquid to contact with the polymer flow just after spinning, cooling and solidifying the yarn and obtaining the fiber having microcapsules stuck to the surface. |
