## 1 Introduction  
In general, 60% of the fine dust in air is composed of the sulfates or nitrates produced by the combination of exhaust gases, such as sulfur oxides (SOx) and nitrogen oxides (NOx), with water vapor or ammonia in air [1, 2]. Therefore, various efforts have been made to reduce the air pollutants that produce fine dust, particularly in the construction industry [3, 4]. [PERSON] et al. [3] developed a nanocomposite TiO2 produced from the combination of pure TiO2 and titanium isopropoxide, and showed that its efficiency in removing NOx is better than that of pure TiO2. [PERSON] et al. [4] showed that a higher NOx removal rate was exhibited in a concrete block coated with TiO2 compared to that imbedded with TiO2. However, most of the existing studies on the removal of air pollutants are based on chemical adsorption by the photocatalyst titanium dioxide (TiO2). The adsorption efficiency of TiO2 in external environmental conditions, such as washing and freeze thawing, is much lower because TiO\({}_{2}\) is soluble in water [5]. In addition, the techniques applied in the construction industry have only focused on the removal of NOx, whereas the removal of fine dust particles has received limited attention [6]. Hence, in the construction industry, the techniques for removing stable air pollutants and fine dust particles in external environments are required. Textile fabrics made of polypropylene or polyester formed from fibers with various small diameters are commonly used in the construction industry. Static electricity can be effectively induced by friction in these textile fabrics through rubbing their surfaces. The static electricity can easily cause fine dust particles to adhere to the fabrics owing to the movement of charges. [PERSON] [7] reported the adsorption of fine dust particles by static electricity in dried polyester fabrics. [PERSON] et al. [8] reported that the fine dust particle removal rate in textile fabrics increased with the applied voltage. Meanwhile, zeolite has a large polarization and effectively forms covalent bonds with SO\({}_{x}\), which has dipole moments in ranges similar to that of zeolite [9; 10]. [PERSON] et al. [11] studied the reproducibility of the NOx removal rate by zeolite and reported that the NOx removal rate in zeolite was maintained above 90% throughout 27 times repeats of the experiment. [PERSON], and [PERSON] [12] proposed a mechanism for the surface adsorption of SO\({}_{2}\) on zeolite. The polarization of coconut shell activated carbon is relatively very low, and effectively forms covalent bonds with NOx, which has dipole moments in similar ranges to that in coconut shell activated carbon [9; 13]. In addition, coconut shell activated carbon can physically adsorb NOx because its pore size is similar to the movement range of the NOx gas molecules [14]. [PERSON] et al. [15] reported that the NOx removal rate of coconut shell activated carbon was improved by 40% after plating the surface of the coconut shell activated carbon with Cu. [PERSON] et al. [16] showed that coconut shell activated carbon with more micropores exhibited a higher NOx removal rate. These results imply that the combination of textile fibers and zeolite or coconut shell activated carbon could be very effective in reducing air pollutants and fine dust particles. Hence, a coating method for textile fibers that maintains a stable air pollutant and fine dust particle removal rate in external environments is required. The objective of this study is to propose an effective coating method for textile fabrics and evaluate the removal rates of nitrogen oxides (NO\({}_{x}\)), sulfur oxides (SO\({}_{x}\)), and fine dust particle in the coated textile fabrics. To effectively reduce the fine dust particles using static electricity, textile fibers made of polyester were used. Zeolite and coconut shell activated carbon were used as porous materials to remove SO\({}_{x}\) and NOx, respectively.
