Problems solved by technology

The traditional antistatic finishing agent is a surfactant, which is usually used to treat fibers or fabrics, but its antistatic effect, washing resistance and durability are poor, and it will be affected by factors such as climate and use environment
The application of carbon black or conductive polymer composite conductive fiber makes the antistatic effect of textiles remarkable, durable and not affected by factors such as environmental humidity, but because carbon black or conductive polymer composite conductive fiber is gray-black or dark green, it is not It is suitable for the finishing of light-colored textiles, so its application range is greatly limited

Abstract

The invention relates to a preparation method of ITO / polyester composite conductive fabric through the sol-gel method, which comprises the following steps: (1) dissolving metal indium in inorganic acid to prepare a solution; (2) adding SnCl4.5H2O into the solution, carrying out magnetic stirring, heating to 75 DEG C-85 DEG C till the viscosity of the solution is increased and colorless transparent ITO sol is formed, standing the sol for 24-48 hours for aging, and then obtaining ITO inorganic gel; and (3) adding anhydrous ethanol into the inorganic gel, carrying out the magnetic stirring, further adding polyethylene glycol and a bonding agent, increasing the temperature to 70 DEG C-80 DEG C, heating in a water bath, stirring for 5-8 hours, and then adding polyester fabric; and drying. The method is simple, low in cost and applicable to industrial production; and the obtained conductive fabric has good antistatic property, and the color has little change before and after treatment.

Description

technical field [0001] The invention belongs to the field of preparation of polyester composite conductive fabric, in particular to a preparation method of sol-gel method ITO / polyester composite conductive fabric. Background technique [0002] ITO (Indium Tin Oxides), the Chinese name is indium tin oxide. ITO is a highly degenerate N-type semiconductor, which has attracted great attention for its high visible light transmittance and infrared reflectivity, excellent electrical conductivity and good etching performance. ITO film has the characteristics of good conductivity, transparency to visible light, and strong reflectivity to infrared light. It has been widely used in LCD TVs, energy-saving windows for buildings, solar cells, and car windshields. In addition to the many uses mentioned above, ITO films can also be used as conductive electrodes for devices such as camera tubes, electroluminescent panels, and plasma displays, for electrostatic shielding, heat reflective sel...
