Influence of fiber diameter on filtration performance of polyester fibers

Abstract

The filtration performance of four kinds of coarse polyester filters commonly used in the market was studied experimentally. The results showed that these filter materials had better filtration efficiency for particles larger than 5 μm. There was a significant difference among the same grade filters on filtration efficiency and resistance. The maximum counting efficiency of all four Samples can be achieved when the filtration velocity was 1.1 m/s. Fiber diameter was one of the main influencing factors that affect the efficiency and resistance of polyester filters. The comprehensive effect was relatively good when the Sample fiber diameter was small.

Spatiotemporal Distribution of PM_2.5 and Its Correlation with Other Air Pollutants in Winter During 2016~2018 in Xi’an, China

“…Scholars from different countries carried out some types of corresponding measures and research to solve the existing environmental pollution problems at the same time, and to create a good indoor and outdoor environment [14][15][16][17][18][19][20][21][22][23][24][25]. For example, plants reduced many pollutants such as volatile organic compounds, carbon monoxide, nitrogen and sulfur oxides, particles, formaldehyde, and heavy metals [14,15].…”

“…It was more important to breathe safe and clean fresh air in the building environment. More scholars were focusing on the research and development of new filter materials and the performances of air filters to jointly provide measures for a good living environment [23][24][25].…”

Variation of Particulate Matter and Its Correlation with Other Air Pollutants in Xi`an, China

“…Some results had been achieved, and the main focus were on composing particulate matters [14], the limits of the standards [15], regional studies [16], human health and the correlation between particulate matters and other pollutants [17]. In addition, more scholars were also focusing on the research and development of new air filter materials to control the concentration of particulate matter [18,19]. Also some types of corresponding measures and research were carried out to solve the existing environmental pollution problems [20][21][22][23][24][25].…”

Selection of air filters for residential fresh air in China based on the control of PM2.5

“…However, people are now paying more attention to the filtration efficiency [8], air filtration systems [9], different materials [10][11][12], and the matching energy of consumption problems [13]. Although some results had been achieved, research on selecting air filters in fresh air was not enough (GB/T 18883-2002).…”
