Embodiment 1

[0048] 1kg of tourmaline powder (such as figure 1 Shown) is fully dispersed in 5kg of ethanol aqueous solution, wherein the ratio of water and ethanol in the ethanol aqueous solution is 5:95, and the pH value of the system is adjusted to 3 by using oxalic acid and ammonia water. Then 0.15 kg of n-butyl titanate was added dropwise, stirred evenly and then reacted for 2 hours. Subsequently, the aqueous solution containing 0.03 kg of cerium nitrate hexahydrate was added dropwise, and the reaction was continued for 2 h. During the above reaction, continuously utilize ammonia water to adjust the pH value of the system. Then the overall temperature of the reaction system was raised to 70°C and aged for 10 hours, and the tourmaline powder was separated by suction filtration, and the tourmaline powder was filtered and cleaned, and then placed in a nitrogen atmosphere at a temperature of 800°C in a muffle Sinter in the furnace for 8h to obtain tourmaline / titanium dioxide / cerium dioxi...

[0054] (1) Fully disperse 1 kg of dried tourmaline powder in 5 kg of ethanol aqueous solution, wherein the ratio of water and ethanol in the ethanol aqueous solution is 15:85, and use oxalic acid and ammonia water to adjust the pH value of the system to 4. Then 0.05kg of titanium tetrachloride was added dropwise, stirred evenly and reacted for 2 hours. Subsequently, an aqueous solution containing 0.01 kg of lanthanum nitrate hexahydrate and 0.01 kg of praseodymium nitrate hexahydrate was added dropwise, and the reaction was continued for 2 hours. During the above reaction, continuously utilize ammonia water to adjust the pH value of the system. Then the overall temperature of the reaction system was raised to 70°C and aged for 5 hours, and the tourmaline powder was separated by suction filtration, and the tourmaline powder was filtered and cleaned, and then placed in a helium atmosphere at a temperature of 600°C. Sinter in a furnace for 5 hours to obtain tourmaline powder dop...

Embodiment 3

[0060] (1) Fully disperse 1 kg of dried tourmaline powder in 5 kg of ethanol aqueous solution, wherein the ratio of water and ethanol in the ethanol aqueous solution is 10:90, and use oxalic acid and ammonia water to adjust the pH value of the system to 2. Then, 0.05 kg of n-butyl titanate was added dropwise, stirred evenly, and reacted for 2 hours. Subsequently, an aqueous solution containing 0.01 kg of lanthanum nitrate hexahydrate, 0.01 kg of praseodymium nitrate hexahydrate and 0.01 kg of cerium nitrate hexahydrate was added dropwise, and the reaction was continued for 2 hours. During the above-mentioned reaction, continuously utilize ammonia water to regulate the pH value of the system (PH value=2). Then the overall temperature of the reaction system was raised to 60°C and aged for 8 hours, filtered and washed with absolute ethanol to obtain tourmaline powder, and the tourmaline powder was filtered and cleaned and then placed in a nitrogen atmosphere at a temperature of 7...

Abstract

The invention relates to a preparation method of negative ion polyester fiber, a negative ion cord fabric prepared from the polyester fibers obtained by the preparation method and application of the negative ion polyester fiber. The preparation method comprises the following steps of dispersing dried negative ion powder in an ethanol aqueous solution, regulating the pH value of a system by using a regulator, adding a titanium-containing compound, dropwise adding an aqueous solution of a rare earth compound, and performing aging, separating and sintering in the reaction system to obtain doped negative ion powder; adding an abrasive solvent through a ball mill to grind doped tourmaline powder, adding acid anhydride, and performing grinding and heat preservation to obtain co-doped and graft-modified negative ion nanoparticles; and blending and granulating the negative ion nanoparticles and polyester particles, and carrying out melt spinning to obtain the negative ion polyester fiber. The negative ion cord fabric provided by the invention has a negative ion emission function, and generated negative oxygen ions can react with dust and microorganisms in the air and react with organic matter to promote the dust and the microorganisms to be decomposed into non-toxic low-molecular products, so that the effect of purifying the environment in a vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a preparation method of anion polyester fibers, cords and applications thereof. Background technique [0002] Polyester fiber is the largest variety of synthetic fiber and is widely used in various fields of human life, but its functionality is relatively simple. With the development of the economy and the improvement of people's living standards, automobiles have become a daily necessity in people's daily life. However, the release of organic pollutants in automobiles and their purification and suppression are a major problem that plagues people. [0003] The car sunroof is a standard part of the car at present, and its main purpose is to provide the car with a wider field of view and a better sense of space. At the same time, the car sunshade can effectively adjust the light in the car. But these have not effectively solved the problem of volatile organic compounds (VOC) ...
