Description
Technical field
The present invention relates to the silver-plated fields of cloth, more particularly to a kind of nylon fabric silver plating process.
Background technique
With the development of modern industry, the especially development of electronics industry, wireless communication technique, people inevitably by
To electromagenetic wave radiation, radiation-proof cloth comes into being, if the anti-radiation clothes owner of early stage is engaged in radar, the portions such as microwave communication
The staff of door uses.But now with the universal of the household electrical appliances such as refrigerator, micro-wave oven, mobile phone, amount of radiation is not yet in life
It is disconnected to increase, with when many special populations, for example work in the medical worker of Chemical Examination Material in Hospital department, work in cable optic fibre factory
Testing staff, the ready-to-be mothers being even pregnant are wearing radiation-proof garment, and present radiation-proof garment is thick and heavy, not wash resistant.
It is wherein silver-plated on cloth, radiation protection can be played the role of, however the breaking strength of most of clothes is low, elasticity
Difference, wear-resisting property is poor, and cloth cannot have preferable interaction with silver, cause silver-plated effect poor, prevents cloth from playing anti-spoke
The effect penetrated.
Summary of the invention
Based on this, it is necessary to a kind of nylon fabric silver plating process is provided, to overcome the above problem.
A kind of nylon fabric silver plating process, by silver chemical liquid phase deposition, is realized using nylon fabric as flexible substrate
Polyamide fibre surface is silver metallized, and the silver chemical liquid is made of oxidation solution and reducing solution, and the oxidation solution includes silver salt solution, complexing
Agent, the reducing agent are formaldehyde, constantly deposit to matrix surface to restore Ag+ in deposition liquid.
Further, the silver salt uses silver nitrate, is used as the source of supply of Ag+.
Further, the complexing agent uses ammonium hydroxide, for Ag+ is complexed, and Ag+ concentration is reduced, in the solution with Ag
(NH3) 2+ form exists.
Further, comprising the following steps:
(1) prepare nylon fabric matrix: nylon fibre cloth being put into industry washer and is cleaned, and is dried with INDUSTRY SPINDRYER.
(2) it modulates silver chemical liquid: silver nitrate is mixed with water, ammonium hydroxide is then added dropwise into silver nitrate, solution is raw first
Produce sepia Ag2O precipitating continues that ammonium hydroxide is added dropwise, will form [Ag (NH3)2] OH complex compound, reaction equation is as follows:
⇋
⇋
(3) deposition of silver: nylon fabric matrix is put into silver chemical liquid, and reducing agent formaldehyde and hot water is then added, is restored
Reaction, and by electric heating, the silver in solution is restored to and is covered on nylon fabric matrix surface, by silver-plated nylon fabric
Its reaction equation is as follows:
→
(4) the silver-plated nylon fabric dehydration drying obtained step (3), then air-dried by air-conditioning or electric fan.
(5) it examines, packed products.
The beneficial effects of the present invention are:, by chemical liquid deposition, realizing polyamide fibre using nylon fabric as flexible substrate
Surface is silver metallized, prepares polyamide fibre conductive fabric.The breaking strength of polyamide fibre is high, and density is low, and line density is small, and elasticity is good, wearability
Can be excellent, in addition polyamide fibre surface has polar group, has preferable interaction with silver.
