Abstract
The invention relates to colored special-shaped super fine denier polyester monofilaments and a production method thereof. The colored special-shaped super fine denier polyester monofilaments are prepared from, by mass, 1-5% of anti-aging capsules, 5-10% of pigment, 5-10% of PEN slices, 1-3% of a dispersing agent and the balance polyester slices. The PEN slices, the polyester slices, the anti-aging capsules, the pigment and the dispersing agent are extruded and mixed together through a screw machine and then melted, melt is prepared and subjected to melt spinning through a special-shaped spinneret plate, and the colored special-shaped super fine denier polyester monofilaments are obtained. Due to the fact that PEN is added, the heat resistance of fibers is improved, and thus the roll sticking phenomenon is avoided when the heat setting temperature is higher than 245 DEG C; meanwhile, due to the higher heat setting temperature, disorientation of an orientation structure of an amorphous area is accelerated, the internal stress of the fibers is reduced, and thus the dimension stability of the fibers is improved; the setting temperature is raised, the mobility of macromolecular chains in the fiber structure is enhanced, the degree of crystallinity is increased, the content of an amorphous area is reduced, and the boiling water shrinkage is reduced.
