Problems solved by technology

[0006] The technical problem to be solved by the present invention is to develop an automobile leather production process with infrared heat reflection and cooling function, which can effectively reflect heat energy when exposed to high temperature, that is, reflect infrared rays of the heat source in sunlight irradiated on the surface of automobile interior leather. In the air, the temperature of the exposed leather surface can be effectively reduced by nearly 20 degrees (compared with the temperature of normal leather after exposure), so as to solve the problem of car leather hardening after high temperature exposure, easy aging, unstable color, discomfort after human contact, etc. , so that car leather seat users can fully enjoy the natural comfort brought by leather

Embodiment

[0017] A production process of automobile leather with infrared heat reflection and cooling function, including fleshing → deliming → softening → tanning → shaving → retanning, dyeing, fatliquoring → drying → softening → covering layer finishing → embossing → color layer Finishing→Functional layer coating and other steps, for the steps mentioned in particular, follow the normal operation, and the tanning steps are followed by salting and pickling and chrome powder tanning, salting and pickling is: the skin after softening and washing, the liquid ratio is 25% , taking skin as the mass of 100 parts, add 25 parts of water, control the temperature at 20±2°C, add 5 parts of sodium chloride, control the Baume degree to 6.0-7.0, react for 20 minutes, add 0.5 parts of 10wt% dilute Formic acid, add 0.3 parts of 10wt% dilute formic acid after reacting for 10 minutes, add 0.7 parts of 5wt% dilute sulfuric acid after reacting for 10 minutes, add 0.7 parts of 5wt% dilute sulfuric acid twice...

Abstract

The invention relates to the field of industrial leather manufacturing, in particular to a production process of automobile leather with an infrared heat reflecting cooling function. The production process comprises the steps of meat removal, deliming, softening, tanning, shaving, retanning, dyeing and fat liquoring, drying, milling, covering layer coating, embossing, color layer coating and functional layer coating. In the steps of tanning, retanning, dyeing, fat liquoring, drying and coating, the related physical properties of the leather are effectively improved under the action of reasonable raw materials, components, reaction temperature, time and the like, heat source infrared rays in sunlight irradiating the surface of automotive trim leather are reflected to the air, and the temperature of the surface of insolated leather is effectively reduced by about 20 DEG C. Therefore, the bad phenomena that after automobile leather is insolated at high temperature, the automobile leather is hardened, easy to age and instable in color, and discomfort is generated after the human body is in contact with the automobile leather are solved.

Description

technical field [0001] The invention relates to the field of industrial leather manufacturing, in particular to an automobile leather production process with infrared heat reflection cooling function. Background technique [0002] At present, middle and high-end cars are covered with high-grade leather. This kind of leather for automobiles is usually made from cowhide through fleshing, deliming, softening, tanning, retanning, dyeing, fatliquoring, drying, softening, and painting. Generally, the operating environment is relatively harsh, and it is common to park in the open air and be exposed to high temperatures. The temperature of the black car interior can reach up to 110-120 degrees. Therefore, the general automobile leather (black) generally has the following problems in use: [0003] 1. In summer, the temperature of black car interior leather can reach up to 110-120 degrees, people will feel very uncomfortable when sitting in it, and it will take a long time for the te...
