With the diversification of people's demand for textile functions, the preparation of multifunctional fabrics is still a current research hotspot. In this study, the water-soluble epoxy compound N, N-bis(oxiran-2-ylmethyl) hexane-1,6-diamine (EH) was introduced into cellulose macromolecule blended fabrics (cotton/modal) by two-phase vaporization technique, resulting in excellent wrinkle, hydrophobicity, and certain UV protection effects. It could be observed by electron microscopy that EH formed a polymer film on the fiber surface. In addition, the results of EDS scans and fiber swelling rate tests showed that EH was uniformly distributed and formed a cross-linked structure in the amorphous zones inside the fibers. Compared with the control fabrics, the wrinkle recovery angle of the EH-treated fabric was increased by 39.7 %. The fabrics could reach a contact angle of 136.9°, providing excellent hydrophobic effect. In addition, the fabrics achieved certain UV protection effects (UPF of 50+). The EH-treated fabrics were less stabilized in strong acid and alkali conditions, but exhibited greater durability in other environments. In summary, the internal and external synergistic effects of EH in forming polymer films on the fibers surface and internal cross-linking structures provided a cleaner, simple, and feasible method for the preparation of multifunctional cellulose macromolecule fibers textiles.

N1,N6-双(环氧乙烷-2-基甲基)己烷-1,6-二胺内外协同制备多功能纤维素高分子混纺面料

随着人们对纺织品功能需求的多样化，多功能织物的制备仍然是当前的研究热点。本研究采用两相汽化技术将水溶性环氧化合物N,N-双(环氧乙烷-2-基甲基)己烷-1,6-二胺(EH)引入纤维素高分子混纺织物(棉/莫代尔)中，从而产生优异的抗皱性、疏水性以及一定的防紫外线效果。通过电子显微镜可以观察到EH在纤维表面形成了一层聚合物薄膜。此外，EDS扫描和纤维溶胀率测试结果表明，EH在纤维内部的非晶区均匀分布并形成交联结构。与对照织物相比，EH处理织物的折皱回复角增加了39.7%。织物的接触角可达136.9°，具有优异的疏水效果。此外，该面料还取得了一定的防紫外线效果（UPF为50+）。经过 EH 处理的织物在强酸和强碱条件下稳定性较差，但在其他环境中表现出更高的耐用性。综上所述，EH在纤维表面形成聚合物薄膜和内部交联结构的内外协同作用，为制备多功能纤维素高分子纤维纺织品提供了一种清洁、简单、可行的方法。
