Integration of hydrophobic and antibacterial functionalities into polyester-cotton blended (PTCO) textiles has attracted more attention but remains a challenge. Here, a Janus fabric with antibacterial effect, hydrophobicity, and enhanced moisture-permeability is fabricated using a "mist polymerization" approach. The PET fibers in the PTCO fabric are amino-functionalized through ammonolysis reactions of PET molecules with HDA, and mist treatments of poly lauryl methacrylate (PLMA) and poly(DMC-co-MA) (PDM) are applied on the two side surfaces of the PTCO-HDA fabric, respectively. The resulting Janus fabric exhibits an antibacterial rate of 99.9% against both E. coli and S. aureus, along with a hydrophobic property on its single side (PTCO-HDA@PLMA). Additionally, the establishment of a surface-free energy gradient across the fabric confers superior moisture-permeability to the Janus fabric, offering advantages in preserving textile comfort. Moreover, this approach does not significantly compromise the original fabric properties, such as mechanical strength, moisture permeability, and fabric softness. The proposed method offers a straightforward and scalable strategy for textile finishing, demonstrating great potential in expanding the application scope of PTCO fabrics, and it may hold a pivotal role in diverse applications, notably encompassing home textiles, wound dressings, and high-performance sportswear.
将疏水和抗菌功能集成到聚酯棉混纺（PTCO）纺织品中已引起更多关注，但仍然是一项挑战。在此，采用“喷雾聚合”方法制备了一种具有抗菌效果、疏水性和增强透湿性的双面织物。PTCO织物中的PET纤维通过PET分子与HDA的氨解反应进行氨基功能化，并分别在PTCO-HDA织物的两个侧面进行聚甲基丙烯酸月桂酯（PLMA）和聚（DMC-co-MA）（PDM）的喷雾处理。所得双面织物对大肠杆菌和金黄色葡萄球菌的抗菌率均为99.9%，且其单面（PTCO-HDA@PLMA）具有疏水性。此外，在织物上建立的表面自由能梯度赋予了双面织物优异的透湿性，在保持纺织品舒适性方面具有优势。而且，这种方法不会显著损害原始织物的性能，如机械强度、透湿性和织物柔软度。所提出的方法为纺织品后整理提供了一种直接且可扩展的策略，在扩大PTCO织物的应用范围方面显示出巨大潜力，并且它可能在多种应用中发挥关键作用，特别是包括家用纺织品、伤口敷料和高性能运动服装。
