Surface Deposition on Cellulose Substrate via Cationic SiO₂/TiO₂ Hybrid Sol for Transfer Printing Using Disperse Dye

Abstract

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 ζ potential −11.9 mV, surface tension 34.7 mN/m, and average particle size 20–100 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.

Status and Development of Transfer Printing in Textiles—A Review

“…It is usually performed by first printing a disperse dye onto paper and then transferring the dye onto a substrate by sublimation and diffusion into the hydrophobic fabric at elevated temperatures. 5,6 When combined with carrier printing, transfer printing has revolutionized the traditional textile industry due to its market competitiveness. Additionally, it offers faster production speeds, more flexible manufacturing modes, and more delicate printing patterns compared with other traditional methods 7 in terms of operation/stages, low cost, 8 required care, and energy consumption.…”

“…Various solutions to the limitations of transfer printing onto substrates such as natural fiber fabrics have been studied. 6,11,12,14,15,18–22 Modification of the transfer medium and/or the substrates has extensively increased the application of transfer printing in many fields, including textiles. New dyes, such as dyes that contain α-bromoacrylamido or β-bromoacrylamido groups, were used in transfer printing on wool via chemical reaction.…”

Çok Tabakalı ZnO veya TiO2 Kaplanmış %100 Pamuklu Kumaşların Dispers Boyarmaddelerle Transfer Baskı Yöntemine Göre Basılması

“…Söz konusu çalışmalarda 65/35 poliester/pamuk karışımı kumaşlar kullanılarak çeşitli kimyasallarla ön işlemler yapılmıştır. %100 pamuklu kumaşların dispers boyarmaddelerle transfer baskısıyla ilgili ise literatürde sadece bir tane çalışma bulunmaktadır [20]. Bu çalışmada pamuklu kumaş SiO 2 /TiO 2 nanoparçacıklarla soljel yöntemiyle kaplanmış ve ardından transfer baskı işlemi yapılmıştır.…”

“…dye sublimation ink which is used in wide-format printers [2]. Yin et al [3] applied cationic SiO 2 /TiO 2 hybrid sol (CSTHS) to coat a cellulosic substrate to improve its surface properties. They investigated using dispersed dyes to inkjet the coated paper and the subsequent heat transfer effect.…”
