The morphological structure of melt-spun polyester fibers observed in the microscope has a circular cross section and no special longitudinal structure. The filamentous fibril structure can be observed under the electron microscope. The special-shaped fibers can change the elasticity of the fibers, make the fibers have special gloss and bulkiness, and improve the cohesion and covering ability of the fibers, as well as the properties of anti-pilling and reducing static electricity. For example, triangular fibers have flash effect; pentafoliate fibers have fat luster, good handle, and anti-pilling; hollow fibers because of the internal cavity, small density, good warmth retention.

Therefore, Yinxiang's sewing yarn fabrics made of high-quality polyester fibers have excellent luster, good handle, good color fastness, non-pilling, non-fading, heat resistance and thermal insulation. They are the best synthetic fibers and have good light resistance.
