Influence of aminopropyl/vinyl/silsesquioxane post-treatment on the colour performance of pigment-based inks on ink-jet-printed polyester fabrics

The present research manages the utilisation of post-treatment coating solutions of aminopropyl/vinyl/silsesquioxane (APSV) for ink-jet printing of polyester with CMYK (cyan, magenta, yellow and key [black]) pigmented water-based ink-jet inks. The proposed protocols could effectively fix the pigment colours on polyester at a low relieving temperature under the thermal initiation or ultraviolet (UV)-radiation of vinyl terminated groups in APSV compared to the commercial textile binders. The colorimetric data and fixation, antistatic properties, roughness and durability of the ink-jet-printed samples were studied. The outcomes demonstrated that APSV successfully fixed the pigment-based ink-jet inks on polyester fabric, and could achieve significantly higher colour performance and degree of fixation than the commercial textile binders. The APSV-post-treated examples had durable antistatic properties and soft handle. The durability tests indicated that the ink-jet-printed polyester fabrics post-treated with APSV retained a higher degree of fixation and antistatic properties after 10 launderings. In general, the outcomes revealed that APSV can be successfully utilised as a pigment binding agent, eliminate all determinant drawbacks in works of literature for treatment of fabrics in ink-jet printing application, such as the fabric handles and the many approached methods. Moreover, it showed a good durable antistatic finish for the post-treatment of ink-jet-printed polyester fabrics.
