This paper describes an evaluation method for nonwoven fabrics using an image analysis technique. Nonwoven fabrics used for coverstocks, filters, and interlinings were used for this study. They were made from polyester, polyethylene, polypropylene, and rayon using chemical, meltblown, spunbond, and thermal bonding system. Three properties (air permeability, tensile property, and fiber orientation) of the fabrics were evaluated in the study. The circle radius inscribed in the polygons of the pores in the nonwoven fabrics were represented by the gamma distribution function. The mean and variance of the gamma distribution function were related to air permeability. Fiber orientation was predicted by analyzing the fiber orientation in the image. The most probable radius and the mean and variance of the radius of the gamma distribution function would predict the filtration property.
