Nylon 6 Filament FDY&POY&DTY Nylon Filament

Textile Polyamide/Nylon Filament The morphological structure of the nylon obtained by the melt-spinning method observed in the microscope has a circular cross-section and no special longitudinal structure. Filamentous fibrils can be observed under an electron microscope, and the fibrils of nylon 66 are about 10-15nm wide. If a special-shaped spinneret is used, it can be made into nylon with various special cross-sectional shapes, such as polygonal, multi-lobed, hollow and other special-shaped cross-sections. Its focused state structure is closely related to the stretching and heat treatment in the spinning process. The macromolecular main chains of different nylons are all connected by carbon atoms and nitrogen atoms. The special-shaped fiber can change the elasticity of the fiber, make the fiber have special luster and bulkiness, and improve the cohesion and covering ability of the fiber, as well as anti-pilling, reducing static electricity and other properties. For example, th…
