Abstract
Using the sectional stochastic fractal variable, a texture of nonwoven fabrics was easily characterized. A recent development of fractal theory makes it possible to construct a mathematical model for the texture of nonwoven fabrics by using the so-called fractal dimension. Reformulating the fractal dimension as the sectional stochastic fractal variable, the texture of the nonwoven fabric was described with the sectional stochastic fractal variable. With the aid of the well-known theory of maximum likelihood method, the algorithm for categorizing the nonwoven fabrics was proposed. This algorithm was numerically checked by using the actual data.
