Abstract
With the increasingly serious air pollution, it is urgent to build a good indoor environment. How to improve performance of filter fiber materials has become the mainstream approach. In this article, the structure and filtration performances of nonwoven filter fibers before and after impregnation with carbon black were tested and analyzed. The results showed that a carbon black coating layer was wrapped on the surfaces of the changed nonwoven fabric filter fibers. The porosity of fibers decreased from 97.81% to 95.35%. The filtration efficiency of PM1.0, PM2.5, and PM10 increased by 16.8%, 28.0%, and 11.7%, respectively, at the best filtration velocity of 0.8 m/s. The filtration efficiency of PM2.5 had the most significant improvement. But the resistance increased by 1.18 times at the same time. The matching between filtration efficiency and resistance should be considered in using. This study provides reference value for the synthesis and application of new filter materials.

Air pollution has a serious impact on people’s daily life
At a filtration velocity of 0.8 m/s, the filtration efficiency difference of PM10, PM2.5, and PM1.0 was 4.81%, 6.74%, and 3.48%, and the filtration efficiency of PM1.0, PM2.5, and PM10 was increased by 16.8%, 28.0%, and 11.7%, respectively
The conclusions are given as follows: 1. A carbon black coating layer was formed on the surfaces of nonwoven filters after impregnation with carbon black
Summary
Air pollution has a serious impact on people’s daily life. It poses many dangers to people’s lives and health. People are paying more attention to a series of problems which were caused by air pollution.[1,2,3] Some literature works showed that indoor particulate matter concentration was much higher than that of outdoor environment.[4,5] They would cause different degrees of harm to human bodies living in the environment, even death.[6,7] people may spend as much as 80%– 90% of their time indoors.[8,9] So, a good indoor environment is an important condition for living
