Embodiment 1

[0033] A preparation method of antistatic and antibacterial polyester filter base cloth, comprising the following steps:

[0034] A. Dissolve silver nitrate and cesium chloride in deionized water, stir, add ammonia water dropwise, adjust the pH value to 8-12 to form a suspension, then add micron calcined shell powder to the suspension, continue stirring for 3.5h, Dry the water at 105°C, roast at 850°C for 2 hours, and pass nitrogen gas during the roasting process to protect it from oxidation and obtain modified shell powder;

[0035] B. Use gelatin as the capsule shell to coat modified shell powder and nano silicon dioxide to form microcapsules;

[0036] C. Add the microcapsules to the melted polyester chips, and after mixing evenly, the polyester chips are spun at high speed on a spinning machine to make nascent fibers. The specific process conditions are: spinning temperature 285°C, spinning speed 1220m / min, to obtain polyester primary fiber;

[0037] D. The as-spun fiber...

Abstract

The invention discloses a preparation method of antistatic and antibacterial dacron filtering base cloth. A mode of mixing caesium ions with silver ions, mixing with shell powder and then roasting ischosen, gelatin is added to prepare a microcapsule, and then the microcapsule is added into a dacron fiber, so that the antibacterial property of the dacron filtering base cloth is obviously improved;due to the addition of the caesium ions, the caesium ions are combined with other anions to synthesize a compound of a special structure (cesium chloride is of a face-centered cubic structure with the coordination number of 8), the structure can better protect the silver ions, so that the silver ions can give the antibacterial property into fuller play; according to the prepared antistatic and antibacterial dacron filtering base cloth, the antibacterial property of the base cloth is still not affected even after being used for more than one year under the environments of high temperature andhigh humidity, and the base cloth has a long-lasting antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of filter base cloth, in particular to a preparation method of antistatic and antibacterial polyester filter base cloth. Background technique [0002] Filter cloth mainly includes: polyester filter cloth, polypropylene filter cloth, nylon filter cloth, vinylon filter cloth. Filter cloth material performance: acid resistance, weak alkali resistance. Good wear resistance, corrosion resistance and recovery, but poor electrical conductivity. Polyester fibers generally have a temperature resistance of 130-150°C. This product not only has the unique advantages of ordinary felt filter cloths, but also has very good wear resistance and high cost performance, making it the most widely used variety of felt filter materials. . [0003] Polyester long fiber filter cloth material properties: acid resistance, weak alkali resistance, abrasion resistance, corrosion resistance, good recovery, poor electrical conductivity....
