  Abstract

Mercerization and sizing constitute essential pretreatment protocols for optimizing the processability and wear performance of cotton gauze in textile manufacturing. Nevertheless, conventional methodologies relying on high-concentration alkali solutions and non-degradable sizing agents (e.g., polyvinyl alcohol) present critical challenges. To address these limitations, we developed an integrated cellulose/NaOH/urea ternary system (1 wt% cellulose, 7 wt% NaOH, 12 wt% urea) that synergistically achieves fiber mercerization, sizing, and in situ synthesis of silver nanoparticles (Ag NPs) through a single-bath process. Within this system, NaOH was used as a mercerizing agent, while cellulose derivatives served as triple functions: (1) as a green reductant for Ag+ ions, (2) as a stabilizer of Ag NPs, and (3) as a biodegradable sizing matrix. Urea operates as a multifunctional adjuvant through [Ag(NH2)2CO]+. Compared with Ag-NaBH4@GZ, the optimized Ag-140°C@GZ composite demonstrated exceptional functional integration: the attachment of Ag NPs was confirmed through characterization techniques, such as FTIR, XPS, and so on. Notably, the modified gauze still achieved complete sterilization of Escherichia coli within 4 h after 100 accelerated washing cycles. Crucially, functionalization preserved intrinsic textile characteristics with a minimal impact on vapor transmissibility (1079 g/m2/day) while enhancing tensile strength by 25.6%. Biosafety is confirmed via cyto-compatibility assessments. This efficient collaborative process has developed durable medical textiles while addressing issues of antibacterial performance, environmental sustainability, and industrial scalability.
