Abstract

The invention relates to the technical field of metallic functional woven products, and particularly relates to a pretreatment method of conductive polyester fibers, the conductive polyester fibers and a preparation method thereof. The pretreatment method of the conductive polyester fibers comprises the following step: adsorbing a modifying agent on the polyester fibers to obtain modified polyester fibers, wherein the modifying agent is selected from plant polyphenol. According to the pretreatment method, the modifying agent is green and environmentally-friendly, the modifying agent is adsorbed to the surfaces of the polyester fibers through mutual static effect and hydrogen bond effect to form a supermolecule structural film layer which can be used as an interface layer between a metal coating and the polyester fibers, so that the bonding capacity between the metal coating and the polyester fibers can be improved, and no damage is caused to the performance of the polyester fibers; thedefects that the polyester fibers are damaged, and the performance of the fibers are destroyed, and the environmental pollution is caused in a traditional pretreatment method can be overcome. The pretreatment method is simple, easy to control, green and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of metallized functional textiles, in particular to a pretreatment method for conductive polyester fibers, conductive polyester fibers and a preparation method thereof. Background technique [0002] Metallized conductive fiber combines the characteristics of fiber and metal. Compared with other conductive fibers, it has the advantages of small specific gravity and good conductivity, and its good flexibility and cohesion make it flexible and reprocessable. It is blended with ordinary fibers into yarn, and further made into fabrics as conductive, antistatic and electromagnetic shielding materials, which can significantly improve the material's hand feel and air permeability, and reduce the cost of materials. Metallized conductive fibers are widely used in antistatic, electromagnetic shielding, heat radiation resistance, antibacterial, sensors and smart textiles and other fields. [0003] The electroless plati...
