The present invention relates to a splittable nylon/polyester composite fiber with excellent form stability and bulky property. The present invention includes: (i) a single slit component (A) dividing a composite fiber cross section into multiple sections, a nylon 64 random copolymer constituting the slit component (A); and (ii) multiple split components (B) provided with triangular cross sections and positioned in the sections divided by the slit component (A), a polyester polymer constituting the split components (B). In a case where the present invention is applied to a fiber structure, division can be facilitated based on excellent shrinkage characteristics. In addition, the surface area of the split component (B) based on the polyester polymer and exposed to the outside is maximized, a bulky property is given, and thus unique touch, excellent dyeability, and excellent form stability are achieved. Furthermore, sufficient shrinkage can be performed without any additional shrinkage treatment process, and thus manufacturing costs can be reduced, productivity can be enhanced, and a high level of yarn uniformity can be achieved. |
