Method for synthesis of comfortable copolyester

The invention relates to a method for synthesis of comfortable copolyester, wherein the method comprises the following steps: 1) mixing an organic conductive mica nano powder, superfine diatomite, sodium polyacrylate, p-hydroxybenzoic acid and the like with ethylene glycol, propylene glycol and butylene glycol, and preparing a comfortable composite alcohol solution in a liquid ball mill; 2) mixing conductive potassium titanate whiskers, organic sodium based bentonite, sodium alginate and the like with polyethylene glycol and propylene glycol, and preparing a comfortable composite accelerant in the ball mill; and 3) mixing a certain proportion of the comfortable composite alcohol solution with ethylene glycol and terephthalic acid, carrying out a reaction, adding the comfortable composite accelerant in a middle stage of the reaction, and then further carrying out condensation polymerization to prepare the comfortable copolyester. The prepared comfortable copolyester can improve wearability of the polyester mat
