摘　　要：本文通过对现行常规铬鞣法铬鞣剂分子发生水解配聚及皮胶原羧基发生离解的定量研究，找出胶原羧基和铬鞣剂分子发生最大结合的条件，并由此提出高吸收铬鞣的作用机理和相应的高吸收铬鞣工艺——高ｐＨ值铬鞣法。The research of the hydrolyzing and polymerizing of anion polymerizing of anion and neutral chrome complexes and the ionization of collagen carboxyl groups using normal chrome method were introduced in this paper, and the reaction conditions of the highest absorption of chrome tanning agent molecules to collagen carboxyl groups were found. As a result of this, the high exhaustion chrome tanning mechanism and its technology-chrome tanning system at high pH value were put forward.
