Abstract
Polyester is one of the textile materials that are widely used, with different forms as textile or yarns or fibres. This depends on the properties of the polyester polymer and the final application that is used in it. Staple and crimps polyester fibres (poly-fil®) have also been used for comfort applications in addition to the durability property. The general use of crimps polyester fibres as alternatives of fillings for pillows and mattresses. This research is aiming to enhance the staple and crimpy polyester fibres with Phase Change Material (PCM) to give the ability to change their thermal state in a large range to use it as a filling or compressed sheet for thermal protection of different purposes, regardless of ambient temperatures. So, short and crimps polyester fibres treated in a simple way using Octadecane as (PCM material) loaded on Pectin/Stearic acid and Alginate/Stearic acid to form PCM composite treatment materials. The properties of the fibres were evaluated after treatment with Differential Scanning Calorimetry (DSC), Scanning Electron Microscopy (SEM), in addition to the Physico-mechanical properties. It can conclude that; the polyester fibres can be covered with PCM composites and the covered one has a preferable result over its uncovered. Also, after the evaluation of blank/uncovered and covered polyester fibres properties, it was these treatments enhanced the mechanical and physical properties of fibres, and they kept and maintain the fibres crimps shape to achieve the air changing. Additionally, acquisition of the required thermal properties to reach the state of thermal stability.
