In the study, microencapsulation of 1-tetradecanol, a phase change material, into the natural and biocompatible gelatin/gum arabic wall structure to be used for the development of thermoregulating cotton fabrics was carried out by the complex coacervation method. The morphology and particle size distribution of the produced microcapsules were investigated using scanning electron microscopy (SEM) and particle size analysis. The chemical structure of the microcapsules was determined using Fourier transform infrared attenuated total reflectance spectroscopy (FTIR-ATR). Their thermal properties were analyzed through differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis. The microcapsules with an average particle size of 22.24 µm had a spherical morphology, a very high latent heat absorption capacity (143.96 J/g) and good thermal stability. Microcapsules were applied to cotton fabrics at concentrations of 100 g/l, 200 g/l, and 300 g/l using the impregnation method. The morphology, thermoregulation properties, air permeability, bending rigidity and tear strength of microcapsule treated fabrics were investigated and the effect of capsule concentration on these properties was analyzed. It was determined that microcapsule applied fabrics showed temperature regulation feature and felt maximum 2 °C warmer than untreated fabric in cold environment. Although the air permeability of the fabrics decreased with increasing capsule concentration, there was no observed impact on the weft tear strength. In addition, it was determined that microcapsule application up to a concentration of 200 g/l did not affect the bending resistance of the fabrics.
