New approaches to improving thermal regulating property of cellulosic fabric

To enhance the thermoregulation property of cotton fabric, new materials have been prepared to be used for encapsulating phase change materials (PCMs). The new material has been prepared via esterification reaction between different carboxylic acids and different fatty acids crossed with diglycol compounds, these materials were characterised to be used as hosting materials for octadecane, which is heat storing material suitable for textile applications. FT-IR and DSC analysis were used to characterise the prepared hosting material. The prepared materials have special shape which has different cavity distance between its side chains, and also have a reactive group on the backbone of its structure which make these materials able to react chemically with cotton fabric to help it to be not leakage from the treated surface (permanent) and the material will be stable on the fibre surface even after washing. When applied onto textile materials, the treated fabric shows good thermoregulation property.
