Abstract
Void structure in textiles may be characterized by a variety of methods, including many based on nuclear magnetic resonance (NMR). The NMR techniques are based on the measurement of fluid distribution or diffusion within porous media, and are therefore particularly relevant for characterizing the void space that governs fluid interactions and movement within textile substrates. In this article, we describe the use of NMR imaging, also known as magnetic resonance imaging, to measure average void dimensions in textile fabrics. In addition to direct visualization using NMR images, void space may be analyzed by calculating the fluid density autocorrelation function. The advantages of both types of data analysis are discussed. These NMR techniques are applied to a water-saturated nylon fabric and the results compared to void sizes measured from optical microscopy.
