Development of a Phase Change Material (PCM) Measurement Methodology for Fabric Surface Quantification

---

Abstract

Phase change materials (PCMs) have unique chemical compositions that allow them to change phases from solids to liquids when a specific temperature is reached, providing a cooling sensation to the user. The durability of PCM finishes over the material or product’s useful life is not well known, nor is there a standardized procedure for quantifying the presence of PCMs on the fabric’s surface. Therefore, the purpose of this research was to develop and analyze the efficacy of a microscopic evaluation methodology for fabric surface quantification of PCM finishes. A pilot study was conducted on 100% polyester athletic t-shirts with a proprietary encapsulated printed PCM finish applied to the back side of the fabric. Microscopic images were taken in three locations from each shirt at the same coordinates using a Nikon inspection microscope (iNEXIV VMA-2520 model) at 120X magnification. Results indicate the methodology developed was effective for fabric surface quantification.
