摘　　要：为了扩展角蛋白的应用范围,在羊毛角蛋白溶液中用界面聚合的方法制备了含羊毛角蛋白的相变微胶囊。借助激光粒度仪、扫描电镜(SEM)、红外光谱仪(FT-IR)、热分析仪(DSC和TG)等方式研究了微胶囊的粒度及其分布、表面形貌、分子结构、相变潜热和热稳定性。用微胶囊乳液对棉织物进行浸轧整理,并对其性能进行测试。结果表明:所制备的含羊毛角蛋白相变微胶囊平均粒径为8μm,表面光滑圆整、分散良好无黏连;热分析显示包覆率为46.45%,相变潜热为121.13 J/g,微胶囊耐热温度为182℃。经浸轧处理后微胶囊形态基本保持完整,可以较好地整理到棉织物表面,整理后的棉织物具有调温性能,经、纬向断裂强力和断裂伸长率均提高,但其透气性能下降18%。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（ TG） 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 μm. 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 ℃. 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 %.
