Direct to Garment (DTG) inkjet printing is an alternative technology for a more sustanianble printing on textile. This technology uses a computer programmed printhead with an inkjet to propel ink droplet on the fabric. It allows fast customized print, which is desirable for the sport garment market (team logo, names, sponsorship, etc.). This method has lower upfront cost for new design allowing creation of low production run for custom design. Many printing techniques are possible such as acid, dye-sublimation, pigment and reactive. Nevertheless, pigment inks are simpler and more efficient. They are also water-based, meaning the require less solvent, which makes this technology eco-friendly. Unfortunately, water-based pigment inkjet inks have low adhesion on polyester fabric mostly because of loose textile structure for moisture wicking and breathability. Moreover, the low chemical surface energy and low number of chemical reactive sites creates insufficient interaction between the surfaces. Consequently, the low adhesion of the film translates to a low durability of wash cycle. This project aims to increase the inkjet washing durability on polyester fabric with a pre-treatment via three adhesion mechanisms: mechanical, dispersive and chemical.

直接服装 (DTG) 喷墨印花是一种在纺织品上进行更可持续印花的替代技术。该技术使用带有喷墨装置的计算机编程打印头来推动织物上的墨滴。它允许快速定制打印，这对于运动服装市场来说是理想的（团队标志、名称、赞助等）。此方法的新设计前期成本较低，允许为定制设计创建低产量运行。许多印刷技术都是可行的，例如酸性、热升华、颜料和反应性。然而，颜料墨水更简单、更高效。它们也是水基的，这意味着需要更少的溶剂，这使得该技术更加环保。 不幸的是，水性颜料喷墨墨水在聚酯织物上的附着力较低，主要是因为织物结构疏松，吸湿排汗和透气性差。此外，低化学表面能和低数量的化学反应位点导致表面之间的相互作用不足。因此，薄膜的低粘附力转化为洗涤循环的低耐久性。 该项目旨在通过机械、分散和化学三种粘合机制进行预处理，提高聚酯织物的喷墨洗涤耐久性。
