Embodiment 1

[0029] Deionized water is added in the preparation tank 4 by flowmeter, stops after the accumulative addition amount of deionized water is 1375Kg, and deionized water among the present invention is desalinated water, and in this process, the bottom valve of preparation tank 4 is closed, when deionized water When the deionized water is added to the stirring liquid level, the agitator 41 is started at a low speed, and the rotating speed of the agitator is 120rpm at this time, and a 10% sodium phosphate solution is configured at the same time, and 450 g of the prepared 10% sodium metaphosphate solution is poured into the preparation tank 4 , and then take 15 bags of titanium dioxide, each bag of titanium dioxide weighs 25 kilograms. The present invention adopts Konnos titanium dioxide 1073, slowly pours it into the feeding hopper, and evenly adds it into the preparation tank after being pre-dispersed by the vibrator 3 . After all the titanium dioxide has been added to the prepara...

[0031]Deionized water is added in the preparation tank 4 by flowmeter, stops after the accumulative addition amount of deionized water is 1375Kg, and deionized water in the present invention is desalinated water, and in this process, the bottom valve of preparation tank 4 is closed, when deionized water When the deionized water is added to the stirring liquid level, the agitator 41 is started at a low speed, and the rotational speed of the agitator is 120 rpm. Configure 10% sodium phosphate solution simultaneously, get 450g and prepare 10% sodium metaphosphate solution and pour in the preparation tank 4, then get 15 bags of titanium dioxide, and the weight of every bag of titanium dioxide is 25 kilograms. The present invention uses Konnos titanium dioxide 1073, slowly pours it into the hopper, and evenly adds it to the preparation tank 4 after being pre-dispersed by the vibrator 5 . After all the titanium dioxide has been added to the preparation tank 4, the agitator 41 is ope...

Embodiment 3

[0033] Deionized water is added in the preparation tank 4 through the flow meter, and stops after the cumulative addition of deionized water is 1000Kg. The deionized water in the present invention is desalinated water. In this process, the bottom valve of the preparation tank 4 is closed. When the deionized water is added to the stirring liquid level, the agitator 41 is started at a low speed, and the rotational speed of the agitator is 120 rpm. Configure 8% sodium phosphate solution simultaneously, get 450g and prepare 8% sodium metaphosphate solution and pour in the preparation tank 4, then get 12 bags of titanium dioxide, and the weight of every bag of titanium dioxide is 25 kilograms. The present invention uses Konnos titanium dioxide 1073, slowly pours it into the hopper, and evenly adds it to the preparation tank 4 after being pre-dispersed by the vibrator 5 . After all the titanium dioxide has been added to the preparation tank 4, the agitator 41 is operated at a high s...

Abstract

The invention discloses a process for preparing a chinlon delustering agent. The process comprises the following steps of: (1) adding deionized water into a preparation tank and adding a dispersing agent in an amount which is 0.1 to 0.3 percent of the mass of titanium dioxide, wherein the dispersing agent is 8 to 12 percent metaphosphate solution; (2) predispersing; (3) mixing the titanium dioxide, the deionized water and the metaphosphate solution uniformly; (4) dispersing the titanium dioxide to be below 1 mu m by using a dispersing pump and cooling titanium dioxide suspension to 20 to 35 DEG C by using a cooling device, wherein the dispersing pump and the cooling device are connected with the outlet at the bottom of the preparation tank; (5) conveying the titanium dioxide suspension into a settling tank to settle at the temperature of between 20 and 35 DEG C for 18 to 30 hours; and (6) conveying the titanium dioxide suspension subjected to settlement into a storage tank. The invention also discloses equipment for preparing the chinlon delustering agent. By the process and the equipment for preparing the chinlon delustering agent, the preparation time of the titanium dioxide is reduced; the dispersing ratio and the utilization ratio of the titanium dioxide are increased; and spinning broken ends are reduced.

Description

Technical field [0001] The invention involves the field of spinning slices, which specifically involves the preparation process of a nylon consumer optical agent and the equipment for the preparation process for nylon anti -optical agent. Background technique [0002] Nylon is the earliest synthetic fiber in the world, that is, polyacide fiber, which is called nylon internationally. It has high strength, good elasticity, soft feel, and abrasion resistance.field.Nylon usually needs to be light in the production process to improve the obvious luster on the surface of the nylon and the wax texture on the surface.Titanium dioxide is usually used as a consumer in the process of production of nylon slices.The refractive index of titanium dioxide is 2.60, which has good lighting effect, and has the advantages of non -toxic, insoluble in water, heat resistance and chemical stability.During the production of nylon slices, nylon products are semi -lighting products or full -optic products ...
