摘要
在这项研究中,使用靛蓝进行了天然染色研究,并使用氢氧化钠、氢氧化钙和碳酸钙作为碱比较了染色性。作为还原剂,比较了亚硫酸氢钠和葡萄糖。为了采用更环保的方法,使用葡萄糖作为还原剂,氢氧化钙作为碱,用天然靛蓝对 3D 打印热塑性聚氨酯(TPU)材料进行染色。研究了热塑性聚氨酯材料在各种条件下的染色性。研究了染色 3D 打印热塑性聚氨酯材料的耐光、耐摩擦和耐洗涤色牢度。当葡萄糖浓度为 15 克/升、氢氧化钙浓度为 10 克/升时,K/S 值显著增加,显示出 PB 系列的颜色。随着染色温度、染色时间和靛蓝染料浓度的增加,K/S 值呈上升趋势。但靛蓝染料浓度的影响不明显,染色温度为 90 ℃、染色时间为 60 分钟后,K/S 值没有明显增加。耐光色牢度较差,但耐洗涤和耐摩擦色牢度较好。因此,用葡萄糖代替亚硫酸氢钠进行靛蓝染色可以实现更环保的 3D 打印热塑性聚氨酯材料染色。
Eco-friendly Indigo Dyeing of 3D-Printed Thermoplastic Polyurethane Material Using Glucose and Calcium Hydroxide
In this research, natural dyeing studies were conducted using indigo, and dyeability was compared using sodium hydroxide, calcium hydroxide, and calcium carbonate as bases. As a reducing agent, sodium hydrosulfite and glucose were compared. For a more environmentally friendly method, 3D-printed thermoplastic polyurethane (TPU) materials were dyed with natural indigo using glucose as the reducing agent and calcium hydroxide as the alkali. The dyeability of TPU materials was investigated under various conditions. The color fastness to light, rubbing, and washing of dyed 3D-printed TPU materials were investigated. At a 15 g/l glucose concentration and a 10 g/l calcium hydroxide concentration, the K/S value increased significantly, showing the color of the PB series. The K/S value tended to increase as dyeing temperature, dyeing time, and indigo dye concentration increased. However, the effect of indigo dye concentration was not significant, and there was no significant increase after the dyeing temperature was 90 °C and the dyeing time was 60 min. The color fastness to light was poor, but for washing and rubbing the fastness was good. Therefore, it was confirmed that more environmentally friendly 3D-printed TPU material dyeing is possible by indigo dyeing using glucose by replacing sodium hydrosulfite.
