Melamine formaldehyde microcapsules containing octadecane are synthesized by the
interfacial polymerization method, and the size, shape, and thermal storage/release prop
erties of the synthesized microcapsules are analyzed by FTIR, SEM, and DSC. Polyester
fabrics are then coated with the microcapsules under various conditions of concentration
and time/temperature by the knife-over-roll (KOR) and screen printing (SP) methods. The
thermal, mechanical, and physical properties of the untreated and treated fabrics are
evaluated to identify the best adhesive method. The mean diameter of the microcapsules
ranges from 1 to 1.5 μm, and their shapes are almost spherical. Under the optimum treatment
concentration, temperature, and time, thermal properties after five launderings decrease
rapidly, and the bending and shear rigidities of the KOR fabrics are higher than those of the
sp fabrics. This means that fabrics coated by sp become less stiff and hard than those by
KOR. sp fabrics exhibit higher air permeability and lower hygroscopic properties than KOR
fabrics.
