Colored leather hyperchromic/cleaning agent composite and preparation method thereof

Abstract

The invention provides a colored leather hyperchromic / cleaning agent composite, which comprises the following raw materials in parts by weight: 5-95 parts of leather cleaning agent, 2-98 parts of darkening agent, 5-95 parts of film forming agent, 1-81 parts of solvent and 2-98 parts of dye-fixing agent, wherein the darkening agent is one or more of chitin, chitosan, silicone oil compounds, rare earth and resin (refractive index: less than 1.5). According to the invention, various auxiliary materials such as the darkening agent and the dye-fixing agent are added into the leather cleaning agent so as to obtain the colored leather hyperchromic / cleaning agent composite; and by using the composite, the original colors of colored leathers after being cleaned are fixed, and darkened, thereby achieving an effect of always keeping fresh through regular cleaning. The invention also provides a method for preparing the colored leather hyperchromic / cleaning agent composite.

Description

technical field [0001] The invention relates to the technical field of leather cleaning, in particular to a color-enhancing cleaning agent composition for colored leather and a preparation method thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tannin. It has natural grain and luster, and feels comfortable. It includes leather for daily use, such as for making clothing and bags.

AI Technical Summary

Problems solved by technology

Existing leather cleaners are mainly composed of detergents and solvents, which have certain effects on leather such as decontamination, descaling, degreasing, and stain removal. However, after cleaning colored leather, there are more or less dyes or pigments. The phenomenon of being dissolved, which causes the color of colored leather to fade or become lighter and older

In the case of dyes or pigments with good color fastness, the color fading phenomenon of a single wash is usually negligible to the naked eye and does not affect the overall color of the colored leather; but when the washing frequency is high, or the number of washings has accumulated to a certain number At this time, the colored leather will lose its overall color or become lighter in color and become old until the leather is washed and scrapped

Although old colored leather can be refurbished, after a little more refurbishment, a thick coating will be accumulated on the leather surface, thus losing the original grain style, just like artificial leather, and The skin becomes thicker and harder, or even scrapped
