Long-acting leather softener

Abstract

The invention relates to a long-acting leather softener which is prepared from the following raw materials in parts by weight: 6-11 parts of hydroxyphenyl methyl ester, 3-9 parts of surfactant, 4-10 parts of triethanolamine, 2-8 parts of liquid paraffin, 1-5 parts of alkaline proteinase, 4-6 parts of anhydrous sodium chloride, 1.5-4 parts of penetrant T, 8-14 parts of water-based lanolin, 3-8 parts of sulfitated edible vegetable oil, 2-6 parts of Span, 1-3 parts of dehydroacetic acid, 8-14 parts of hydroxyethyl ethylenediamine, 4-6 parts of oxidized sulfited fish oil and 2-7 parts of organic silicon material. The long-acting leather softener has the advantages of long acting time and no harm to the leather, and can prevent the leather from repeated hardening.

Description

technical field [0001] The invention relates to a long-acting leather softener. Background technique [0002] Leather products have become an indispensable commodity in people's daily life, such as leather shoes, leather clothes, sofas, leather bags and other articles for use. However, leather clothes, leather bags, leather shoes, leather sofas, etc. will harden when exposed to water, or the real leather that will harden after being left for a long time. Leather softener is the oil that enters the skin through the pores of the animal dermis, evenly distributes on the surface of the inner fibers, and can be moderately combined with the inner fibers. When the thickness of this layer of grease reaches an appropriate thickness, the friction force of sliding between the fiber surfaces in the skin is equivalent to the friction force between oil molecules, so the leather will be very soft. However, the existing softeners generally have the disadvantages of relatively large odor a...
