Problems solved by technology

However, the existing leather is generally of a single color, and there will be no other changes except aging and fading during use, which leads to a relatively monotonous color during use. If it is used as a raw material for some accessories, it will lack a certain degree of aesthetics

Embodiment 1

[0022] A kind of manufacturing process of discoloration leather of the embodiment of the present invention 1, comprises the following steps:

[0023] The color-changing base liquid is prepared by stirring and mixing the roller coating material with a weight ratio of 70% and the auxiliary liquid with a weight ratio of 30% to make a base liquid; the color-changing base liquid requires sufficient adsorption and is not easy to fall off after coating. Therefore, the requirements for the roll coating material are relatively high, and it cannot be mixed too thinly, otherwise it will fall off easily. The preferred roll coating material is roll coating resin, and the auxiliary liquid is leather treatment agent.

[0024] To prepare the color-changing coating liquid, add the color-changing powder with a weight ratio of 40% into the base liquid, stir and mix evenly to make the color-changing coating liquid; adding the color-changing powder is mainly to make the color-changing base liquid h...

Embodiment 2

[0029] A kind of manufacturing process of discoloration leather of embodiment 2 of the present invention, comprises the following steps:

[0030] The color-changing base liquid is prepared by stirring and mixing 80% by weight of the roller coating material and 20% by weight of the auxiliary liquid to make the base liquid; the color-changing base liquid requires sufficient adsorption and is not easy to fall off after coating. Therefore, the requirements for the roll coating material are relatively high, and it cannot be mixed too thinly, otherwise it will fall off easily. The preferred roll coating material is roll coating resin, and the auxiliary liquid is thinner.

[0031] To prepare the color-changing coating solution, add the color-changing powder with a weight ratio of 30% into the base liquid, stir and mix evenly to make the color-changing coating liquid; adding the color-changing powder is mainly to make the color-changing base liquid have the function of changing color a...

Embodiment 3

[0036] A kind of manufacturing process of discoloration leather of embodiment 3 of the present invention, comprises the following steps:

[0037] The color-changing base liquid is prepared by stirring and mixing the roller coating material with a weight ratio of 90% and the auxiliary liquid with a weight ratio of 10% to make a base liquid; the color-changing base liquid requires sufficient adsorption and is not easy to fall off after coating. Therefore, the requirements for the roll coating material are relatively high, and it cannot be prepared too thin, otherwise it will fall off easily. The preferred roll coating material is roll coating resin, and the auxiliary liquid is leather treatment liquid.

[0038] To prepare the color-changing coating solution, take the color-changing powder with a weight ratio of 20% and add it into the base liquid, stir and mix evenly to make the color-changing coating liquid; adding the color-changing powder is mainly to make the color-changing b...

Abstract

The invention discloses a manufacturing technology of color changing leather. The manufacturing technology comprises the following steps: preparing a color changing base solution, stirring and mixinga roller coating material with the weight percent of 70 percent to 90 percent, and an auxiliary solution with the weight percent of 10 percent to 30 percent to prepare the base solution; preparing a color changing coating solution, adding color changing powder with the weight percent of 20 percent to 40 percent into the base solution, and uniformly stirring and mixing to prepare the color changingcoating solution; manufacturing a leather substrate: carrying out surface technology treatment on corresponding leather to form the leather substrate; coating with the color changing coating solution, fixing the leather substrate and coating the surface of the leather substrate with the color changing coating solution to form a color changing layer; manufacturing the color changing leather and carrying out natural air drying on the leather substrate coated with the color changing coating solution for 12h to 36h to prepare the color changing leather. According to the manufacturing technology of the color changing leather disclosed by the invention, the manufactured and molded color changing leather has diversified appearances and is beautiful and elegant.

Description

technical field [0001] The invention belongs to the technical field of leather processing and manufacturing, and in particular relates to a manufacturing process of color-changing leather. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. Because of its easy processing, it is widely used in people's daily life, and there are more expectations and requirements for leather processing and leather diversification. However, the existing leather is generally of a single color, and there will be no other changes except for aging and fading during use, which leads to a relatively monotonous color during use. If it is used as a raw material for some ornaments, it will lack a certa...
