In this work heat transfer papers were loaded with a new core-shell pigment based on precipitating thin shell of titanium dioxide on a core of rice husk silica ash TiO/RHSA to be applied in dye sublimation printing of textile fabrics. Besides, 0.1% (w/w) cationic polyacrylamide (CPAM) and 1% (w/w) bentonite (Bt) were also added sequentially to improve drainage and filler retention of the paper hand-sheets made from bleached kraft bagasse pulps. The effect of the new core-shell pigment on the mechanical and barrier properties, thermal stability and surface morphology of modified paper sheets were investigated. In addition, the study of transfer printability and ease of dye release from paper to fabric in this heat transfer printing of polyester fabrics using silk-screen printing under different transfer parameters were studied. Also, fastness measurements including washing, light and perspiration of printing polyester fabric were also estimated.
在这项工作中，将一种新型核壳颜料负载在基于沉淀二氧化钛在稻壳硅灰核上的核壳颜料上，用于纺织品的升华染料印花。此外，还顺序添加了 0.1%（w/w）阳离子聚丙烯酰胺（CPAM）和 1%（w/w）膨润土（Bt），以改善由漂白牛皮纸浆制成的纸页的排水和填料保留率。研究了新型核壳颜料对改性纸页的力学性能、阻隔性能、热稳定性和表面形态的影响。此外，还研究了在不同的转印参数下，使用丝印在聚酯织物上的热转印印花中，从纸转移到织物的印花可转移性和染料释放容易程度。还评估了印花聚酯织物的耐洗性、耐光性和耐汗性等牢度测量。
