Embodiment 1

[0019] The present invention proposes a leather surface printing process, comprising the steps of:

[0020] S1: Select the treated leather, and arrange the outer surface of the leather. It is necessary to ensure that all parts are on the same level, and then measure the thickness of the leather to judge the depth of the printing. After completion, set aside;

[0021] S2: Clean the leather treated in S1 several times, then dry it, and spray a layer of surfactant on the printed area, and the spray should be uniform, and then place the leather under the condition of 45 degrees Celsius, Take it out after the temperature of its surface rises by 40 degrees Celsius;

[0022] S3: Put the heated leather in S2 on the printing device quickly, and print according to the printing depth measured in S1, and during the printing process, the temperature must be at 40 degrees Celsius in real time. After the printing is completed, then print on it Spray the color paste in the area, and then use...

Embodiment 2

[0032] The present invention proposes a leather surface printing process, comprising the steps of:

[0033] S1: Select the treated leather, and arrange the outer surface of the leather. It is necessary to ensure that all parts are on the same level, and then measure the thickness of the leather to judge the depth of the printing. After completion, set aside;

[0034] S2: Clean the leather treated in S1 several times, then dry it, and spray a layer of surfactant on the printed area, and the spray should be uniform, and then place the leather under the condition of 50 degrees Celsius, After the temperature of its surface rises by 44 degrees Celsius, take it out;

[0035] S3: Put the heated leather in S2 on the printing device quickly, and print according to the printing depth measured in S1, and during the printing process, the temperature must be at 44 degrees Celsius in real time. After the printing is completed, then print on it Spray the color paste in the area, and then us...

Embodiment 3

[0045] The present invention proposes a leather surface printing process, comprising the steps of:

[0046] S1: Select the treated leather, and arrange the outer surface of the leather. It is necessary to ensure that all parts are on the same level, and then measure the thickness of the leather to judge the depth of the printing. After completion, set aside;

[0047] S2: Clean the leather treated in S1 several times, then dry it, and spray a layer of surfactant on the printed area, and the spray should be uniform, and then place the leather under the condition of 55 degrees Celsius, Take it out after the temperature of its surface rises by 47 degrees Celsius;

[0048] S3: Put the heated leather in S2 on the printing device quickly, and print according to the printing depth measured in S1, and during the printing process, the temperature must be at 47 degrees Celsius in real time. After the printing is completed, then print on it Spray the color paste in the area, and then use...

Abstract

The invention discloses a leather surface printing process. The leather surface printing process comprises the following steps: spraying a layer of surfactant in a printing area of leather, spraying evenly, putting the leather under the condition of 45-50 DEG C, rapidly putting the processed leather on a printing device at the real-time temperature of 40-50 DEG C, spraying a color paste in the printing area, drying the surface of the printing area through a drying mechanism, coating a color fading agent in a non-printing area on the surface, removing the color paste in the non-printing area, spraying a color fixing agent in the printing area again, spraying evenly, drying under the environment of 45-50 DEG C, cleaning again after the color fixing agent is fixed, removing an impurity on thesurface while processing, and obtaining the surface printed leather. The leather surface printing process meets requirements of different people, the leather in the printing area is processed again,and the leather is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of leather surface treatment, in particular to a leather surface printing process. Background technique [0002] The leather industry covers the main industries such as tanning, shoemaking, leather clothing, leather goods, fur and its products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories.
