[Abstract]:Polyester fiber (PET), as one of the largest synthetic fibers, developed rapidly in the 19 th century. With the development of polyester fiber, the modification technology of polyester fiber has been developing. The diversification, new type, high function and high performance of polyester fiber have been the focus of attention. Polyester fiber has excellent comprehensive properties. The research on functional modification of polyester fiber has been continuously developed. This paper focuses on hydrophobic conductive modified polyester fabric. Based on the homogeneous coating modified polyester fabric, conductive particle carbon black was added to endow the homogeneous coated fabric with electrical conductivity. Conductive polyester fabric with surface resistance at several hundred ohs was prepared. The washing properties, mechanical properties and thermodynamic properties of conductive fabrics were studied. The experimental results show that the surface resistance of the homogeneous coated conductive polyester fabric is up to several hundred ohs, and the washing resistance, mechanical properties and heat resistance of the fabric are good. On the basis of homogeneous coating and the principle of solvent-induced crystallization, the rough surface with micro-nano structure was prepared by solution-precipitation method, and the hydrophobic property of polyester fabric was given. The effects of polyester content and solvent treatment time on the hydrophobic properties of fabrics were studied. The experimental results show that the water contact angle of polyester fabric is about 140 擄, and the polyester fabric has good heat resistance and mechanical properties. A hydrophobic conductive polyester fabric with good properties was prepared on the basis of homogeneous conductive polyester fabric. The effects of the content of polyester, carbon black and solvent treatment time on the hydrophobic conductivity of homogeneous coatings were studied. The optimum treatment process was obtained. The surface resistance of the hydrophobic conductive polyester fabric was several hundred European, and the water contact angle was about 140 擄. On the basis of the hydrophobic conductive polyester fabric, the hydrophobicity of the fabric was improved by controlling the solvent-induced crystallization process, and the contact angle of the fabric reached about 150 擄. The effects of solvent treatment temperature, solvent concentration and solvent treatment time on hydrophobic properties of conductive polyester fabric were investigated. The experimental results show that the increase of solvent treatment temperature is favorable to the formation of solvent-induced crystallization at 55 鈩，
