- Abstract
In order to further explore the applications of keratin, phase-change microcapsules containing keratin were successfully synthetized through interfacial polymerization with keratin as emulsifier. The microcapsules were experimentally examined for their size and distribution,microscopic morphology, molecular structure, latent heat and thermal stability through laser particle sizer, scanning electron microscope (SEM), fourier transform infrared (FT-IR) tests, differential scanning calorimetry tests (DSC) and thermogravimetric (T G) tests. Cotton fabrics were padded and finished with microcapsule emulsion and their mechanical properties were tested. The experimental results showed that the phase change microcapsules containing keratin were prepared successfully with an average particle size of 8 (xm. The SEM micrographs demonstrated that the microcapsules have regular spherical shapes with good dispersion and no adhesion between each other. The thermal properties indicated that the covering rate of the microcapsules is 46. 45%, the phase change enthalpy was 121. 13 J / g and could withstand heat up to 182 t. The morphology of microcapsules remained intact and could be treated to the fabric surface through padding. Additionally, the finished cotton fabrics exhibited thermal controllable performance, their breaking strength and elongation at break in both warp and weft were improved, but their air permeability decreased by 18%.
