MD and CD - Nonwoven Tools
Nonwoven TERMS. For the informed employee md and cd . Nonwoven machines do not make uniform fabric. There are always differences be- tween the machine direction, abbreviated MD, and the cross machine direction, abbrevi- ated CD. These differences show up as differences in tensile strength, elongation, tear strength, and fiber orientation. Most of the time we want the material to behave the same in both directions in the finished product, but this is seldom possible. So we often have to settle for trade offs in the various fabric characteristics to make an acceptable fabric for the customer.
