文摘

A novel cationic SiO₂/TiO₂ hybrid sol (CSTHS) is synthesized and coated onto the surface of a cellulose substrate to rebuild a characteristic surface, which is beneficial to transfer printing from transfer paper printed by disperse dyes. The CSTHS presents a stable disperse state with 味 potential 鈭?1.9 mV, surface tension 34.7 mN/m, and average particle size 20鈥?00 nm. A dense and firm cationic SiO₂/TiO₂ hybrid film is coated on the surface of the cellulose substrate after modification, and the components of the cellulose fibers with or without modification are changed. The K/S value of the coated cellulose substrate is significantly enhanced by 320%, and the transfer rate of the disperse dye is increased to 89% from 21%. The saturation C* of the coated cellulose substrate is increased sharply, and the wet rubbing fastness is improved half a grade. The printed pattern on the treated cellulose fabric shows obviously improved appearance compared to that on the original cellulose fabric. The modified pathway with CSTHS sets the stage for fully exploiting the potential to transfer printing on a cellulose substrate with disperse dyes.
