Silver and titanium-silver nanoparticles have unique properties that make the textile industry progress through the high quality of textiles. Preparation of AgNPs and TiO-Ag core-shell nanoparticles in different concentrations (0.01% and 0.1% OWF) and applying it to cotton fabrics (Giza 88 and Giza 94) by using succinic acid 5%/SHP as a cross-linking agent. Ultra-violet visible spectroscopy (UV-Vis), X-ray diffraction (XRD), dynamic light scattering (DLS), zeta potential, transmission electron microscopy (TEM), scanning electron microscopy/energy-dispersive X-ray (SEM-EDX) are tools for AgNPs and TiO-AgNPs characterization and the treated cotton. The resulting AgNPs and TiO-AgNPs were added to cotton fabrics at different concentrations. The antimicrobial activities, UV protection, self-cleaning, and the treated fabrics' mechanical characteristics were investigated. Silver nanoparticles and titanium dioxide-silver nanoparticles core-shell were prepared to be used in the treatment of cotton fabrics to improve their UV protection properties, self-cleaning, elongation and strength, as well as the antimicrobial activities to use the produced textiles for medical and laboratory uses and to increase protection for medical workers taking into account the spread of infection. The results demonstrated that a suitable distribution of prepared AgNPs supported the spherical form. Additionally, AgNPs and TiO-AgNPs have both achieved stability, with values of (- 20.8 mV and - 30 mV, respectively). The synthesized nanoparticles spread and penetrated textiles' surfaces with efficiency. The findings demonstrated the superior UV protection value (UPF 50+) and self-cleaning capabilities of AgNPs and TiO-AgNPs. In the treatment with 0.01% AgNPs and TiO-AgNPs, the tensile strength dropped, but the mechanical characteristics were enhanced by raising the concentration to 0.1%. The results of this investigation demonstrated that the cotton fabric treated with TiO-AgNPs exhibited superior general characteristics when compared to the sample treated only with AgNPs.
银和钛银纳米粒子具有独特的性质，使纺织工业通过高质量的纺织品取得进步。以琥珀酸 5%/SHP 为交联剂，在不同浓度（0.01%和 0.1%OWF）下制备 AgNPs 和 TiO-Ag 核壳纳米粒子，并将其应用于棉织物（Giza 88 和 Giza 94）。紫外可见分光光度法（UV-Vis）、X 射线衍射（XRD）、动态光散射（DLS）、zeta 电位、透射电子显微镜（TEM）、扫描电子显微镜/能谱（SEM-EDX）是 AgNPs 和 TiO-AgNPs 及处理后的棉纤维的表征工具。所得的 AgNPs 和 TiO-AgNPs 以不同浓度添加到棉织物中。研究了其抗菌活性、紫外防护、自清洁以及处理后织物的机械性能。制备银纳米粒子和二氧化钛-银纳米粒子核壳，用于处理棉织物，以提高其紫外防护性能、自清洁、伸长率和强度，以及抗菌活性，以便将所生产的纺织品用于医疗和实验室用途，并增加对医务人员的保护，以防止感染的传播。结果表明，AgNPs 具有合适的分布，支持其球形形态。此外，AgNPs 和 TiO-AgNPs 均达到稳定状态，zeta 电位分别为（-20.8 mV 和-30 mV）。合成的纳米粒子有效地扩散并渗透到纺织品的表面。研究结果表明，AgNPs 和 TiO-AgNPs 具有较高的紫外防护值（UPF50+）和自清洁能力。在处理 0.01%AgNPs 和 TiO-AgNPs 时，拉伸强度下降，但当浓度提高到 0.1%时，机械性能得到增强。研究结果表明，与仅用 AgNPs 处理的样品相比，用 TiO-AgNPs 处理的棉织物具有更好的综合特性。
