A single treatment that makes textiles multifunctional is very attractive to the textile chemical processors. In this study, multifunctional acrylic fibers were produced by in situ forming silver (Ag) nanoparticles at various concentrations of Ag and trisodium citrate (TSC). The exhaustion of silver into acrylic fibers and the reduction of Ag to Ag nanoparticles were carried out at 90 °C, well above the glass transition temperature (T_g) of this fiber in water. The effect of the concentration of Ag, Ag to TSC ratio, pH, and reaction time on the color strength, ultraviolet (UV) radiation absorption, surface electrical resistance and mechanical properties of the treated fibers were systematically investigated. It was found that if the concentration of Ag was less than 1% on the weight of acrylic fibers or the Ag to TSC ratio was less than 1:2, no color was produced. The color strength and UV radiation absorption capacity of the treated acrylic fibers increased with an increase in the concentration of Ag, and Ag to TSC ratio, and also with a decrease in the pH. On the other hand, the surface resistance of the treated acrylic fibers decreased with an increase in the concentration of Ag and a decrease in the treatment pH. The treated fibers showed excellent antibacterial activity, UV radiation absorption capacity, and also very good antistatic properties along with an excellent colorfastness to washing. Moreover, the developed treatment is highly durable to washing as after 20 washes the treated fibers lost their antibacterial activity only marginally.

使纺织品具有多功能性的单一处理方法对纺织品化学加工者非常有吸引力。在这项研究中，通过在各种浓度的Ag和柠檬酸三钠（TSC）上原位形成银（Ag）纳米粒子，生产了多功能丙烯酸纤维。银在90°C的温度下（远高于玻璃化转变温度（T _g）在水中的这种纤维。系统地研究了Ag的浓度，Ag与TSC的比率，pH和反应时间对处理后的纤维的色强度，紫外线（UV）吸收率，表面电阻和机械性能的影响。已发现如果Ag的浓度小于丙烯酸纤维重量的1％或Ag与TSC之比小于1∶2，则不会产生颜色。处理后的丙烯酸纤维的色强度和紫外线吸收能力随Ag浓度的增加以及Ag与TSC的比值的增加以及pH的降低而增加。另一方面，处理后的丙烯酸纤维的表面电阻随着Ag浓度的增加和处理pH的降低而降低。处理过的纤维显示出极好的抗菌活性，紫外线吸收能力，以及非常好的抗静电性能以及优异的耐洗色牢度。此外，所开发的处理方法具有很高的耐洗涤性，因为在洗涤20次后，处理过的纤维仅略微丧失了其抗菌活性。
