Abstract

The invention relates to a preparation method of polyamide fiber with a uvioresistant function. The method comprises the following process steps: (1) grinding and mixing titanium dioxide, silicon dioxide and zinc oxide to obtain a mixture, and modifying the mixture by adopting a titanate coupling reagent so as to obtain a modified uvioresistant screening agent; (2) mixing the modified uvioresistant screening agent and polyamide slices, and performing melt extrusion pelleting in a twin-screw extruder so as to obtain uvioresistant master batches; (3) blending the uvioresistant master batches and the polyamide slices to obtain a mixture I, performing heating melting on the mixture I in the twin-screw extruder, and forming long polyamide yarns in an extruding manner from a yarn spraying port of a spinning manifold; (4) quenching and bundling the long polyamide yarns, so as to obtain yarn bundles, and performing primary tensioning, annealing and secondary tensioning on the yarn bundles so as to obtain the polyamide fiber. The polyamide fiber obtained by adopting the method has the good uvioresistant performance, and has the high wearing resisting performance.

Description

Technical field [0001] The invention relates to a nylon fiber, in particular to a preparation method of a nylon fiber with anti-ultraviolet function. Background technique [0002] Nylon is a polyamide fiber, and it is called nylon (nylon) abroad. It is the first industrialized fiber in the world. Industrial production began in 1938. Nylon fiber is widely used in apparel textiles and industrial textiles because of its high strength and excellent wear resistance. [0003] The excellent clothing properties of nylon fiber have been widely recognized by consumers. Polyamide fiber has the characteristics of high strength, high elasticity, and good dyeing performance. However, the anti-ultraviolet ability of nylon fiber is relatively poor, and the ultraviolet rays in sunlight can cause certain damage to human skin through nylon fabric. In recent years, as the ozone layer's hole has been increasing, the ultraviolet rays irradiating the ground from sunlight have gradually increased. Ultr...
