Polyester has excellent performance, in addition to its chemical properties, it has a great relationship with its physical properties. Below is the physical structure of the polyester thread, a brief understanding.
The morphology of the polyester observed in the microscope has a circular cross section and no special longitudinal structure, and a filamentous fibril structure can be observed under an electron microscope. Shaped fibers can change the elasticity of the fibers, giving the fibers a special luster and bulkiness, and improving the fiber's cohesive and covering properties as well as anti-pilling and static reduction.
The special-shaped fibers of the polyester thread greatly improve the performance of the fiber, such as the triangular fiber has a glittering effect, the penta-lobed fiber has a lustrous luster, feels good, and resists pilling. The hollow fiber has the characteristics of small density and good warmth due to the cavity inside.
