Abstract

The invention relates to the technical field of leather chemicals and in particular to a fatting agent for normal-temperature fatting. The fatting agent is prepared from the following components in parts by weight: 50-60 parts of oxidized sulfited oil, 10-15 parts of mineral oil, 10-15 parts of animal oil and 15-25 parts of a surfactant. The fatting agent provided by the invention is excellent in acid resistance, alkaline resistance and electrolyte resistance, and good in performance of bonding with leather fibers; leather fatted by the fatting agent is soft, full and good in wettability; moreover, the fatting agent can be used for fatting the leather at normal temperature.

Description

technical field [0001] The invention relates to the technical field of leather chemical industry, in particular to a fatliquoring agent for normal temperature fatliquoring. Background technique [0002] Fatliquoring in leather production is also called oiling. It is a process of treating leather with oil or fatliquoring agent under certain process conditions, so that the leather absorbs a certain amount of oil and endows the leather with certain physical, mechanical and usable properties. Fatliquoring can make the fibers inside the leather wrapped by lubricating oil or the surface of the fibers to a large number of "oily" molecules through chemical and physical actions, balance the surface energy of the leather fibers, and transform the original high-energy surface into a low-energy surface. Increase the mutual mobility between fibers, so as to prevent the leather from hardening and cracking, and make the leather have good physical and mechanical properties such as elasticit...
