The shape of the nylon buckle
The morphological structure observed by the nylon produced by the melt-spinning method in the microscope has a circular cross-section and no special longitudinal structure. The filamentous fibrillar tissue was observed under an electron microscope. The fibril of nylon 66 was about 10-15 nm in width. Such as the use of special-shaped spinneret, can be made of a variety of special cross-sectional shapes of nylon, such as polygonal, multi-lobed, hollow and other special-shaped cross-section. Its focus state structure is closely related to the stretching and heat treatment of the spinning process. The main chains of different polyamides are made up of carbon and nitrogen atoms.
Shaped fiber can change the elasticity of the fiber, so that the fiber has a special gloss and bulkiness, and improve the fiber's cohesion performance and coverage and anti-pilling, reduce static electricity and other properties. For example, the triangular fiber has a glittering effect; the five-leaf fiber has a fat-like luster, feels good, and resists pilling; the hollow fiber has a hollow interior, a small density, and a good warmth.
