Seeing can be believing.

Seeing Can Be Believing

what you see and feel is not always what you see and feel; a closer look at the structure of nonwoven webs may give further insight into the fabric

Many times we are presented with a nonwoven fabric and told of its properties or we may be questioned about some aspect of it. You lower your eyeglasses and scrutinize, inspect and examine it as best you can with the assistance of your fingers, nose and ears. Do you venture to make a comment at this point? Are you certain about the characteristics and properties of this fabric?

On other occasions we have heard a production person comment that "this fabric is just like the other one but the other one ran better." Obviously this fabric is not exactly like the other one. How do we determine what the differences are and what action should be taken? How important is it to make this determination? What are the costs and savings or other advantages or disadvantages involved?

Few companies in the nonwoven business today have the equipment or staff that are capable of truly analyzing the components of a nonwoven fabric and understanding the analysis. This can be paramount in order to correct a problem but is often more important in learning how to invent, improve or design changes in the fabric or finished product.

There are many tests and other methods to determine or see the properties of the subject. The microscope has been used and continues to be an important method. Recently I was discussing the properties of nonwovens and how to make such determinations with industry consultant Clarke Rodman. Clarke has many years of experience in the filtration area and nonwovens in general. He advised me of such work being done by Fabric Research Laboratories (FRL), Albany International Research, Mansfield, MA. The director, Frederick Campbell, was kind enough to allow us to offer you a few examples of "Seeing Can Be Believing and Understanding" (see accompanying figures).

In looking at these (SEM) scanning electron photomicrographs, you can "see" many properties and characteristics of the structures that are not understandable by other means. I believe they will provoke thought that may lead you to a better understanding of your products and capabilities.
