preparation example Construction

[0037] The preparation method of the anti-ultraviolet polyamide color masterbatch of the present invention adopts the formula of the anti-ultraviolet polyamide color masterbatch described in the present invention. The method specifically includes the following steps: vacuum-drying the polyamide powder, mixing nano-powder of anti-ultraviolet colorant, flame retardant, dispersant, antioxidant and polyamide powder and adding them to a twin-screw extruder , extrusion and granulation to obtain anti-ultraviolet polyamide color masterbatch;

[0038] in:

[0039] The vacuum drying process conditions are: the vacuum degree is stable at 0.05-0.1MPa, the temperature is 100°C, and the heat preservation is 8-10h;

[0040] The technological conditions of the twin-screw extruder are as follows: the processing temperature is 210-240° C., and the screw speed is 200-300 rpm.

Embodiment 1

[0043] This embodiment provides an anti-ultraviolet polyamide color masterbatch, which is composed of the following raw materials in terms of weight percentage: 10% of anti-ultraviolet colorant nano powder, 30% of flame retardant, 0.6% of dispersant, and 0.6% of anti-ultraviolet coloring agent. The oxygen agent is 0.05%, and the polyamide powder is 59.35%.

[0044] Specifically, the preparation process of anti-ultraviolet colorant nanopowder is:

[0045] Step 1, adding perylenetetracarboxylic acid-bis(3,5-dimethylphenyl)imide, cerium sulfide and titanate coupling agent into absolute ethanol, stirring, and centrifuging to obtain a colorant predispersion;

[0046] Step 2: Dissolve antimony chloride in pure acetic acid to prepare a transparent precursor solution. Use a carrier gas at 300°C and use a spray thermal decomposition method to react in the transparent precursor solution to form antimony trioxide. At the same time, the transparent precursor solution Repeatedly and unifo...

Embodiment 2

[0057] This embodiment provides a kind of anti-ultraviolet polyamide color masterbatch, by weight percentage, is made up of following raw materials: anti-ultraviolet coloring agent nano-powder body is 11%, flame retardant is 32%, dispersant is 0.7%, anti-ultraviolet The oxygen agent is 0.05%, and the polyamide powder is 56.25%.

[0058] The preparation method of the anti-ultraviolet colorant nanopowder of this embodiment is the same as that of Embodiment 1.

[0059] This embodiment also provides a preparation method of an anti-ultraviolet polyamide functional fiber, which is composed of the following raw materials in weight percentage: 13% of anti-ultraviolet polyamide color masterbatch, and 87% of polyamide pellets.

Abstract

The invention provides an anti-ultraviolet polyamide color master batch and a preparation method of a functional fiber. The anti-ultraviolet polyamide color master batch comprises polyamide powder, adispersing agent, anti-ultraviolet colorant nanopowder, a flame retardant and an antioxidant. A preparation process of the anti-ultraviolet colorant nanopowder comprises the following steps: step 1, adding perylenetetracarboxylic acid-bis-(3,5-dimethylphenyl)imide, cerium sulfide and a titanate coupling agent into absolute ethyl alcohol, carrying out stirring, and then carrying out centrifuging toobtain a colorant pre-dispersion; 2, dissolving antimony chloride into pure acetic acid to prepare a transparent precursor solution, subjecting the transparent precursor solution to reacting at 300 DEG C in virtue of carrier gas by using a spraying thermal decomposition method so as to generate antimony trioxide, repeatedly and uniformly spraying the transparent precursor solution into the colorant pre-dispersion so as to coat the colorant pre-dispersion with the antimony trioxide generated by the reaction, and carrying out vacuum drying to obtain the anti-ultraviolet colorant nanopowder. According to the method for preparing the polyamide functional fiber, the problems of low color fastness and industrial three wastes of the polyamide fiber in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of colored fibers and relates to polyamide functional fibers, in particular to a preparation method of an anti-ultraviolet polyamide color masterbatch and functional fibers. Background technique [0002] In recent years, the amount of ultraviolet radiation passing through the atmosphere to the ground has increased. As the earliest industrialized synthetic fiber in the world, polyamide fiber has the advantages of wear resistance, high strength, durability, easy washing, not easy to aging, and good processing performance. The anti-ultraviolet performance of the polyamide fiber is poor, especially in special fields such as outdoors. The lack of ultraviolet protection function will lead to changes in the structure and performance of the polyamide fiber, and the functionality will be reduced. Therefore, outdoor textiles put forward higher requirements for the weather resistance of the fiber. . [0003] There are two color...
