The processes for making self-cleaning textile fabrics have been extensively discussed in the literature. However, the exploration of the potential for self-cleaning by controlling the fabrication parameters of the fabric at the microscopic level has not been addressed. The current evolution in 3D printing technology provides an opportunity to control parameters during fabric manufacturing and generate self-cleaning features at the woven structural level. Fabrication of 3D printed textile fabrics using the low-cost fused filament fabrication (FFF) technique has been achieved. Printing parameters such as orientation angle, layer height, and extruder width were used to control self-cleaning microscopic features in the printed fabrics. Self-cleaning features such as surface roughness, wettability contact angle, and porosity were analyzed for different values of printing parameters. The combination of three printing parameters was adjusted to provide the best self-cleaning textile fabric surface: layer height (LH) (0.15, 0.13, 0.10 mm) and extruder width (EW) (0.5, 0.4, 0.3 mm) along with two different angular printing orientations (O) (45° and 90°). Three different thermoplastic flexible filaments printing materials were used: thermoplastic polyurethane (TPU 98A), thermoplastic elastomers (TPE felaflex), and thermoplastic co-polyester (TPC flex45). Self-cleaning properties were quantified using a pre-set defined criterion. The optimization of printing parameters was modeled to achieve the best self-cleaning features for the printed specimens.
文献中已广泛讨论了制造自清洁纺织面料的工艺。然而，尚未涉及通过在微观层面控制面料的制造参数来探索自清洁潜力的问题。当前3D打印技术的发展为在面料制造过程中控制参数并在织物结构层面产生自清洁特性提供了契机。已实现使用低成本的熔融长丝制造（FFF）技术制造3D打印纺织面料。诸如取向角、层高和挤出机宽度等打印参数被用于控制打印面料中的自清洁微观特征。针对不同的打印参数值，分析了诸如表面粗糙度、润湿性接触角和孔隙率等自清洁特征。调整三个打印参数的组合以提供最佳的自清洁纺织面料表面：层高（LH）（0.15、0.13、0.10毫米）和挤出机宽度（EW）（0.5、0.4、0.3毫米）以及两种不同的角向打印取向（O）（45°和90°）。使用了三种不同的热塑性柔性长丝打印材料：热塑性聚氨酯（TPU 98A）、热塑性弹性体（TPE felaflex）和热塑性共聚酯（TPC flex45）。使用预先设定的定义标准对自清洁性能进行量化。对打印参数进行优化建模，以实现打印试样的最佳自清洁特征。
