Direct to garment inkjet printing (DGIP) is an eco-friendly textile dyeing method that utilizes a simple process with a small amount of ink for textile products. In general, water-based pigment ink is printed on the surface of cotton; however, due to the high hydrophilicity of cotton's surface, the ink is absorbed excessively, which causes ink smearing, low color strength, and unstable wet rubbing fastness characteristics. In this study, the surface treatment agent (STA) for DGIP, which improved the color strength, wet-rubbing fastness of cotton, and STA dispersion stability characteristics, was enhanced by controlling the butyl-acrylate (BA, soft segment) and the vinyl-acetate (VA, rigid segment) ratios. The wet-rubbing fastness improved as the BA ratio increased though the color strength and ink sharpness properties deteriorated. The total K/S color strength of the surface-treated cotton using the BA30 condition was improved by 30% wet rubbing fastness class 3–4 than neat cotton, and the ink smearing phenomenon was verified to decrease. Ultimately, an optimal STA condition was established by adjusting the ratio of BA and VA wt% where the DGIP characteristics of printed cotton verified that these were the simplest parameters to adjust for optimal impact.

直接成衣喷墨印花 (DGIP) 是一种环保的纺织品染色方法，它采用简单的工艺，只需少量墨水即可用于纺织品。一般来说，水性颜料墨水是印在棉布的表面上；但由于棉布表面亲水性高，吸墨过多，造成墨迹拖尾，色力低，湿摩擦牢度特性不稳定。在这项研究中，通过控制丙烯酸丁酯（BA，软链段）和乙烯基，增强了 DGIP 表面处理剂（STA），提高了棉的颜色强度、湿摩擦牢度和 STA 分散稳定性特性。 -醋酸盐（VA，刚性链段）比率。虽然颜色强度和油墨锐度性能恶化，但随着BA比率的增加，湿摩擦牢度提高。使用BA30条件的表面处理棉的总K/S色强度比纯棉提高了30%的湿摩擦牢度等级3-4，并且证实了墨污现象减少。最终，通过调整 BA 和 VA wt% 的比率来建立最佳 STA 条件，其中印花棉的 DGIP 特性证实这些是调整以获得最佳效果的最简单参数。
