Spun-lace nonwoven producers measure air permeability and density
There is a relationship between air permeability and fabric characteristics such as fabric weight, thickness and density for many nonwoven types. Vision systems now seek to provide added value for producers by improving the capability around process control tasks such as formation analysis to enable this.
Porosity and air permeability are vital properties in some end-use applications such as filtration, thermal insulation and fluid barriers. Nonwoven structures are used in many technical applications, it is very important for the producer to maintain consistency when producing those structures.
Block statistics is the art of mixing image processing techniques and mathematics. By statistically analyzing an image for density consistency and fiber direction, a manufacturer can deduce that other properties such as air permeability will also be consistent throughout a long production run.
