Abstract

The invention belongs to the technical field of conductivity and discloses a nylon fiber surface chemical silver plating method which comprises the following steps: (1) removing oil, namely putting afixed amount of a fiber into a clean container, and putting an alkali oil remover for reducing surface tension of the fiber into the container; (2) carrying out sensitization treatment with a sensitization liquid A, namely completely soaking the fiber obtained in the step (1) into the sensitization liquid A prepared on site, and enabling the surface of the fiber to adsorb a layer of a metal with catalysis activity; (3) carrying out sensitization treatment on a sensitization liquid B, namely completely soaking the fiber obtained in the step (2) into the sensitization liquid B prepared on site,and forming hydrogen bonds by carbonyl functional groups on the surface of the fiber and carbonyl functional groups in the sensitization liquid B; (4) carrying out activation, namely completely soaking the fiber obtained in the step (3) into a silver amino solution prepared on site; (5) putting a fixed amount of glucose restore into the solution obtained in the step (4). By adopting the method, asilver plated layer with a solid plated layer can be made, and a conductive fiber with good conductivity can be manufactured.

Description

technical field [0001] The invention belongs to the field of conductive technology, and in particular relates to a method for electroless silver plating on the surface of nylon fibers. Background technique [0002] PA, also known as nylon, the chemical name is polyamide fiber. Nylon is the world's first fiber synthesized by the outstanding American scientist Carothers and his research group in 1938. In 1958, the first batch of domestic caprolactam test samples were successfully trial-produced in Jinxi Chemical Factory in Liaoning Province. This synthetic fiber was also called "nylon", which opened the prelude to China's synthetic fiber industry. With the miniaturization of automobiles, the high performance of electronic and electrical equipment, and the acceleration of the lightweight of mechanical equipment, the demand for nylon is increasing, especially as a structural material, nylon is strong, heat-resistant, and wear-resistant. , chemical resistance, low friction coef...
