To provide a process for manufacturing flame-retardant, wear-resistant, anti-sticking and low-voc leather for car seats.SOLUTION: The invention discloses a process for manufacturing flame-retardant, wear-resistant, anti-sticking and low-VOC leather for car seats, comprising a deashing step, a retanning step, a neutralizing step, a fat liquoring step and a finishing step. According to the invention, a nitrogen-phosphorus intumescent flame retardant modifies wear-resistant polyurethane to be used in the finishing step, and an anti-adhesion material reduces the adhesion of the coating. The prepared leather for car seats has better wear resistance and lower VOC on the basis of keeping better flame retardance and low fogging performance, allows further improvement to the absorptivity of a fat liquoring agent, and solves the problem of adhesion of a grain surface layer in the process of static storage of the finished leather.SELECTED DRAWING: None
