Multifunctional cotton textiles that are highly breathable are desirable in a broad range of applications. However, it is still a big challenge to scale up production of such multifunctional cotton textiles. Herein, we developed a simple, scalable, and benign strategy to fabricate highly breathable multifunctional cotton textiles via mild surface modification. The 1,4-dihydropyridine (DHP) ring and gentamycin sulfate (GS) molecules were firmly attached to the cellulose chains under room temperature via a one-pot method. The resulting modified cotton textile showed integrated performances with bright fluorescence, good antibacterial behavior, hydrophobic behavior (contact angle of 134°), and UV-blocking (UPF being up to 69.2), which are very stable toward washing and various solvents. There is no obvious change in the whiteness, thermal stability, and mechanical performance of cotton fabrics after the surface modification. What's more, the air permeability of the modified cotton fabric was up to 31.3 (cm/cm)/s. This study not only focuses on the materials design and large-scale fabrication but also provides stable and multifunctional cotton textiles with broad application prospects for many fields.
具有高透气性的多功能棉纺织品在广泛的应用中都很受欢迎。然而，扩大此类多功能棉纺织品的生产规模仍然是一个巨大的挑战。在此，我们开发了一种简单、可扩展且温和的策略，通过温和的表面改性来制备高透气性的多功能棉纺织品。1,4 - 二氢吡啶（DHP）环和硫酸庆大霉素（GS）分子在室温下通过一锅法牢固地连接到纤维素链上。所得的改性棉纺织品表现出综合性能，具有明亮的荧光、良好的抗菌性能、疏水性能（接触角为134°）和紫外线阻挡性能（UPF高达69.2），并且对洗涤和各种溶剂都非常稳定。表面改性后，棉织物的白度、热稳定性和机械性能没有明显变化。此外，改性棉织物的透气率高达31.3（cm/cm）/s。本研究不仅关注材料设计和大规模制造，还为许多领域提供了具有广阔应用前景的稳定且多功能的棉纺织品。
