光固化型ZnO/季铵化木质素基高分子染料的制备

Preparation of UV-curable ZnO/quaternized lignin-based polymer dyes

摘要:

将季铵化改性的木质素和醋酸锌以水热法设计合成了一种具有花瓣状的QL@ZnO材料，并将其与PTEA和DR60为原料合成的光固化型高分子染料进行复合，以丝网印花方式应用于纺织品上。用FTIR、GPC、DSC等分析了URPD的结构与性能。通过紫外光固化的方式得到的QL@ZnO/URPD印花织物具有良好的色牢度（4-5~5级），由于QL和ZnO的协同效应，使得QL@ZnO/URPD印花织物的UPF值可以达到128.49。

Abstract:

We designed a petal-like QL@ZnO material by hydrothermal method, which was obtained from quaternized lignin(QL) and zinc acetate. It was combined with a UV-curable polymer dye synthesized with PTEA and DR60 and applied to textiles by screen printing. The structure and performance of URPD were analyzed by FTIR, GPC, DSC, etc. The results showed that QL@ZnO/URPD printed fabric obtained by UV-curing had good color fastness (4-5~5 grade). Due to the synergistic effect of QL and ZnO, the UPF value of the QL@ZnO/URPD printed fabric reached 128.49.
