SEAT COVER LEATHER FOR AUTOMOBILE HAVING EXCELLENT DURABILITY AND A FABRICATION PROCESS THEREOF

摘要

PURPOSE: A manufacturing method of seat-cover leather for a vehicle provides seat-cover leather requiring excellent tensile strength and elongation or resistance against pressure or force without exterior deformation. CONSTITUTION: A manufacturing method of a seat-cover leather comprises a re-tanning process (P100) applying a tanning agent to leather passed through a tanning process and a neutralizing process; an elastic material-inputting process (P200) putting a silicon-based elastic material providing elongation for the leather; a dyeing and branching process (P300) adding dye into the leather and adding an anionic branching agent to derive flexibility; and a surface-binding process (P400) binding unreacted elastic material, dye, and branching agent.
