Embodiment 1

[0030] Add 3Kg of spinning oil YMA-12 to a 5L stainless steel container, and then add 0.015Kg (0.5%) of 2-(2‵-hydroxy-5‵-methylphenyl)benzotriazepam to the oil For azole anti-ultraviolet absorber UV-P, stir well to make it evenly mixed. The production process is the same as that of the comparative example. See Table 1 for the experimental data.

Embodiment 2

[0032] Add 3Kg of spinning oil YMA-12 to a 5L stainless steel container, and then add 0.06Kg (2%) of 2-(2‵-hydroxy-5‵-methylphenyl)benzotriazepam to the oil For azole anti-ultraviolet absorber UV-P, stir well to make it evenly mixed. The production process is the same as that of the comparative example. See Table 1 for the experimental data.

Embodiment 3

[0034] Add 3Kg of spinning oil YMA-12 to a 5L stainless steel container, and then add 0.15Kg (5%) of 2-(2‵-hydroxyl-5‵-methylphenyl)benzotriazepam to the oil For azole anti-ultraviolet absorber UV-P, stir well to make it evenly mixed. The production process is the same as that of the comparative example. See Table 1 for the experimental data.

Abstract

The invention relates to a preparation method of uvioresistant aramid fiber. The method comprises the steps that in the para-aramid spinning production process, an appropriate amount of benzinidazole, an appropriate amount of substituted acrylonitrile, an appropriate amount of triazine and an appropriate amount of hindered amine uvioresistant absorbent are added into spinning oil, the mixture is uniformly sprayed on the surface of the aramid fiber through nozzle oil equipment, and the aramid fiber with the surface uniformly attached with the uvioresistant absorbent is produced through spinning equipment. The problems that para-aramid ultraviolet-resistant property is poor, oxidative degradation is likely to occur under ultraviolet light are better solved, and the preparation method can be used for spinning industrial production for preparing the uvioresistant aramid fiber.

Description

technical field [0001] The invention belongs to the technical field of fiber spinning, and in particular relates to a preparation method of an anti-ultraviolet fiber. Background technique [0002] Para-aramid (PPTA) fiber is a high-performance aromatic polyamide fiber, successfully developed by DuPont (DuPont) in the 1960s and first industrialized in the 1970s. The chemical name is polyterephthalamide Phenylenediamine (PPTA), trade name Kevlar, China called aramid 1414. Para-aramid (PPTA) fiber belongs to one of the three major high-performance fiber materials in the country. Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is only about 1 / 5 of that of steel wire. Decomposition does not melt, has excellent high temperature resistance. Therefore, it is widely used in advanced composite materials, protective materials, rubber reinforcement materials, ca...
