摘　　要：为提高有色织物上颜料粒子在热真空环境条件下的耐升华色牢度,考察了颜料萘酚红F3RK颗粒和丝素粉体的表面形貌、粒径和分子结构。采用颜料粒子与丝素粉体混合对织物进行颜色调控,利用负压流体场模拟热真空环境下的热力场,研究了颜料粒子和丝素粉体在不同比例下的吸附性能,并探讨了丝素粉体与颜料粒子之间的相互作用机制,构建了微纳米丝素粉体提升涂料印花织物耐升华色牢度的理论模型。结果表明:丝素粉体通过其比表面积大和含有酰胺键的官能团协同作用解决了有色织物热真空沾色问题,耐升华色牢度达到了5级。该方法对极端环境条件下提高有色织物的耐升华色牢度具有借鉴意义。In order to improve the thermal sublimation fastness of pigment particles on colored fabrics under thermovacuum environmental conditions,surface morphology,particle size and molecular structure of naphthol red F3RK pigment particles and silk fibroin powders were investigated,and the color of the fabric was tuned by mixing pigment particles with silk fibroin powder at different ratios.The subatomospheric pressure is used to simulate the thermal force field in the thermalvacuum environment,under which the adsorption performance was studied under different mixing ratios between pigment particles and silk fibroin powder.The interaction between silk fibroin powders and pigment particles were discussed,and the theoretical model was established.The results show that the silk fibroin powder is effective in improving thermal sublimation of colored fabrics in thermovacuum environmental conditions due to the synergistic effect of its large specific surface area and amido bonds.Employment of this method increases thermal sublimation fastness to level 5.The results of this study are of referencing significance for improving the thermal sublimation fastness of colored fabrics under extreme environmental conditions.
