摘要

采用交联壳聚糖预处理锦纶织物后化学镀银，通过正交试验确定了化学镀银的工艺条件：硝酸银14 g·L^-1，氢氧化钠6 g·L^-1，氨水130 mL·L^-1，时间50 min. 采用扫描电子显微镜与能量分散谱仪（SEM-EDS），X-射线衍射（XRD）观察，表征和评价织物镀层的表观形貌、结构组成和摩擦性能. 结果表明，织物表面无敏化化学镀银层的晶粒细致、分布均匀，尺寸为28.9 nm，(111）面择优取向较明显，耐摩擦性能好.

Abstract

Silver was deposited homogeneously on the surface of polyamide fabric by electroless plating without activation and sensitization. The electroless silver plating process was optimized with the orthogonal array testing strategy. It is found that the optimum conditions are the electroless plating time of 50 min with the concentrations of silver nitrate, sodium hydroxide and ammonium hydroxide being 14 g·L^-1, 6 g·L-1 and 130 mL·L^-1, respectively. The surface morphologies, compositions, and phases of fabric samples were characterized by scanning electron microscopy and energy-dispersive X-ray spectrometry (SEM-EDS), X-ray diffraction (XRD). The wear-resisting property was tested by friction fastness test machine. The results show that the gain size of silver plating layer is 28.9 nm with the preferred orientation along direction (111) and the good wear resistance.
