Abstract

Non-isocyanate polyurethanes have rapidly risen as an environmentally friendly substitute to traditional isocyanate-based polyurethanes. Here, a crosslinked non-isocyanate polyurethane (CNIPU) was prepared with cyclic carbonate, polyamine, and diglycidyl ether via simple ring-opening and transcarbamoylation methods. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy confirm the successful preparation of CNIPU. When the CNIPU is used as the pigment-dyeing binder for cotton fabric, the thermochromic microcapsules can be fixed on the fiber surface. The dyed fabric shows excellent thermochromic property and its color fastness can reach above 4 grade. This work offers an efficient strategy to utilize non-isocyanate polyurethane to fabricate pigment-dyed fabrics with green and sustainable route.

环保型非异氰酸酯聚氨酯颜料染色粘合剂

非异氰酸酯聚氨酯作为传统异氰酸酯基聚氨酯的环保替代品迅速崛起。以环碳酸酯、多胺和二甘油酯为原料，通过开环和转氨基化制备了交联非异氰酸酯聚氨酯（CNIPU）。傅里叶变换红外光谱和x射线光电子能谱证实了CNIPU的成功制备。当CNIPU作为棉织物的染色粘合剂时，可将热致变色微胶囊固定在纤维表面。染色织物具有优良的热致变色性能，色牢度可达4级以上。本研究为利用非异氰酸酯聚氨酯制备绿色可持续染料织物提供了一种有效的策略。一种交联非异氰酸酯聚氨酯粘结剂的合成及其在颜料染色中的应用。
