According to the current economic growth in Japan, the consumption of leather products is rapidly increasing with a diversity of consumer's needs. In order to satisfy these various demands, the combination tannage with chrome and other tanning agents or the retannage is adopted as a tanning procedure rather than relying on single method of chrome tanning. Formaldehyde has long been utilized to produce soft leathers, but there often were the cases to cause skin troubles such as allergic dermatitis. Consequently then as the alternative material, glutaraldehyde (dialdehyde) is currently examined. In this paper, examinations were performed regarding to the sweat resistant characteristic of glutaraldehyde treatment and retanning on with chrome leather. It was proved that the combined treated leather with glutaraldehyde and chrome tanning was excellent one as to the sweat resistancy. This effect would be due to the blocking of the basic groups of collagen fibers with glutaraldehyde and acidic groups with chrome complex salt.
