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

    【課題】難燃性、耐摩耗性、耐粘着性、低VOCのカーシート用皮革製造工程を提供することを課題とする。【解決手段】 本発明は、脱灰工程と、再なめし工程と、中和工程と、加脂工程と、仕上げ工程とを含む難燃性、耐摩耗性、耐粘着性、低VOCのカーシート用皮革製造工程を開示する。本発明は、窒素-リン系膨張性難燃剤で耐摩耗性ポリウレタンを変性して、仕上げ工程に使用され、かつ耐粘着性剤で塗膜の粘着性を低減させる。調製されたカーシート用皮革は、より良い難燃性、低フォギング性を維持することに基づいて、より優れた耐摩耗性及びより低いVOCを有し、加脂剤吸収率をさらに向上し、仕上げした皮革の静置保管過程中の粒子面層粘着問題を解決する。【選択図】 なし
