Abstract

Textile fabrics can be given temperature-adjusting properties by finishing them with formulation of polyethylene glycols (PEGs) and dimethyloldihydroxyethylene urea (DMDHEU) applied in a pad-dry-cure process. This treated fabric increases wearer comfort by lowering or raising its temperature as it is heated or cooled. In addition to thermal properties, these finishes produce improved resistance to abrasion, pilling, static charges, and oily soil deposition. Great increases in water absorbency and moisture regain are also achieved.Property changes in chemically finished fibers and fabrics generally correlate with changes in morphological structures related to the finish. Optical, and transmission and scanning electron microscopy were used to study structural changes in the thermally-adaptable fabrics to better understand property changes, and to modify finishing procedures in order to maximize property improvements. Finished cotton, cotton/polyester, and wool fabrics were studied.
