Abstract

The invention discloses a method for preparing light brown leather with a washing function and relates to the preparation of leather. The method comprises the following steps: 1, changing color of leather blank, and uniformly spraying a coloring agent onto the leather blank through a full-automatic leather spraying machine; and 2, changing color of a finished product, namely placing the leather blank treated in the step 1 into an oil injection table, spraying brown dye liquor onto the leather blank, placing the sprayed leather blank on a polishing machine for spraying a light receiving assistant A at a rotating speed 19 revolutions per second of the polishing machine, then spraying a light receiving assistant B at a rotating speed 9 revolutions per second of the polishing machine, and finally spraying a light receiving assistant C at a rotating speed 9 revolutions per second of the polishing machine. The leather prepared by the method is saturated in color, high in comfort level and unique in color and has an antiqued effect, so that the leather is natural in color and excellent in fixation effect.

Description

[0001] Technical field: [0002] The invention relates to the preparation of leather, in particular to a preparation method of light brown leather with washing function. [0003] Background technique: [0004] Leather is widely used on the surface of daily necessities, such as tables and chairs, sofas, shoe materials, clothing, etc., to add texture, beauty or durability to daily necessities. Leather can be broadly classified into artificial leather and natural leather. Natural leather refers to taking animal fur and drying, cleaning, softening, dyeing, trimming, cutting and other production processes to form a smooth surface and tough texture. [0005] There are following two drawbacks in the finished products processed by existing processing methods: 1. The disabled leather surface cannot be well repaired. Uneven coloring; 2. The brightness is unnatural, the coloring effect is not good, and the color is disordered and unsightly. In order to solve the above technical problems...
