Carbon black, as a pigment, has the characteristics of antiultraviolet and antistatic properties and has a wide range of applications in rubber, smart wear, and textiles. In this study, water-based carbon black with good dispersion properties was prepared by mechanical high-speed shear and applied to a polyester fabric. The particle size, placement stability, and rheology of water-based carbon black were investigated. The carbon black is successfully loaded onto the polyester fabric (PET) by scraping and coating. The effect of carbon black concentration on the antiultraviolet and water-repellent properties of polyester fabric was discussed. The results show that the average particle size of liquid carbon black is 240 nm, PDI = 0.375, the particle size of self-made liquid carbon black in the laboratory is normally distributed, stored for 90 days, and the particle size increases slightly. The relationship between shear stress and shear rate of liquid carbon black can be described by the power exponential equation, and the relationship between viscosity and shear rate can be described by the Morgan Mercer Florin formula. When the amount of CB is 10%, the UV radiation protection factor (UPF) of the PET fabric is 164.66, and the UV resistance of the fabric is more than 2 times higher than that of the original fabric. The water contact angle of the PET/CB fabric is 126.6°. After 300 times of friction and 10 times of washing, the UPF remained 146.01 and 126.61, and the contact angle decreased to 106° and 111.4°, respectively. The air permeability and moisture permeability are improved by 30 and 16%, respectively. When the amount of carbon black is less than 10%, the dry and wet friction fastness of the fabric is higher than 3/4, which provides a new preparation method for functional finishing and dyeing of the polyester fabric.
炭黑作为一种颜料，具有抗紫外线和抗静电特性，在橡胶、智能穿戴和纺织品等领域有广泛应用。本研究通过机械高速剪切制备了具有良好分散性能的水性炭黑，并将其应用于聚酯织物。研究了水性炭黑的粒径、放置稳定性和流变学。通过刮涂成功地将炭黑负载到聚酯织物（PET）上。讨论了炭黑浓度对聚酯织物抗紫外线和拒水性能的影响。结果表明，液态炭黑的平均粒径为240nm，PDI = 0.375，实验室自制液态炭黑的粒径呈正态分布，储存90天后粒径略有增加。液态炭黑的剪切应力与剪切速率之间的关系可用幂指数方程描述，粘度与剪切速率之间的关系可用摩根-默瑟-弗洛林公式描述。当炭黑用量为10%时，PET织物的紫外线防护系数（UPF）为164.66，织物的抗紫外线能力比原织物高出2倍多。PET/CB织物的水接触角为126.6°。经过300次摩擦和10次洗涤后，UPF分别保持在146.01和126.61，接触角分别降至106°和111.4°。透气率和透湿率分别提高了30%和16%。当炭黑用量小于10%时，织物的干湿摩擦牢度高于3/4，为聚酯织物的功能整理和染色提供了一种新的制备方法。
