Newton to make runners more comfortable
Seth Moczydlowski, a graduate student working with MTNW client Philadelphia University, recently won first place in a research poster competition for the American Association of Textile Chemists and Colorists (AATCC). Seth’s project used a Newton thermal manikin to demonstrate that screen printed ink on athletic T-shirts makes the wearer hotter and sweatier.
Running shirts are offered in a variety of styles and colors and are marketed with trademarked names to promote the performance qualities of the fabric. These garments also frequently are screen printed with logos and graphics promoting companies or sponsored running events. Commercial screen printing operations generally use a heat-cured plastisol ink consisting of PVC resin and a plasticizing agent. When cured at around 160°C, the resin particles absorb the plasticizer and merge to create a thin, uniform, plastic film . The film is durable and abrasion resistant to remain visible and intact throughout the life of the garment including repeated washing and drying. Unfortunately, this film also acts as a watertight barrier, reducing the amount of surface area available for evaporation and potentially limiting the wicking performance of the garment….
Seth’s next project will be to use Newton to test specially designed graphics patterns that are intended to make the wearer more comfortable. See Seth's poster here.
