To provide a process for production and hydrophobization of polyester textiles which makes it possible to produce an easy-care polyester textile which is reduced in static electrification which is causative of the adhesion of dirt or dust in conventional dyeing and drying steps for polyester (resistant to soil) and which is improved in the friction durability in aqueous washing and thus exerts function retaining hydrophobizing effect (aqueous soil resistance).

The process for the production and hydrophobization of polyester textiles makes both a dihalogenotriazine compound having a hydrophilic substituent and a polyamino compound coexist in dyeing a polyester textile with a disperse dye and imparts a function for hydrophobization to the polyester textile.
