AI Technical Summary
Existing technologies cannot effectively suppress the fluorescence effect produced by nylon 6 fibers under ultraviolet light excitation, resulting in color distortion and excessive color difference, which makes it difficult to meet the needs of high-end textiles.
A masterbatch was prepared by mixing a single-layer coated pigment with a particle size of 0.5-1.0µm with glossy nylon 6 chips and polyamide auxiliaries and using the sol-gel method. The reaction conditions were controlled to form a uniform coating layer. The prepared fiber maintained the original color and light transmittance of the pigment during melt spinning.
It effectively suppresses the fluorescence effect, with fiber color difference ≤0.5, improving fiber coloring quality and spinning stability, and simplifying the production process.
