Embodiment

[0054] This embodiment describes in detail the production process of the sterilizable leather by taking the natural lychee pattern car seat leather as an example

[0055] (1) Out of the warehouse, usually every 500 square meters is a production unit.

[0056] (2) Sorting of skins, sampling and checking the tear strength of the skins, the requirement is greater than 25N, the thickness is required to be 1.1-1.4mm, the degree of looseness, blood tendons, and growth lines are checked, and the unqualified products are placed in the rejection area according to the standards of the skins. and record.

[0057] (3) Crude skin is softened, put 500 square meters of skin into the softening drum, the temperature of the drum is 43-45 degrees, the humidity is 50-70%, the rotating speed is 18-22 rpm, and the softening time is 6 hours.

[0058] (4) Break the drum out of the soft, put the grain side of the skin upwards and ride on the horse according to the shape of the skin.

[0059] (5) Dus...

Abstract

The invention belongs to the field of leather making chemistry and technology engineering, and particularly relates to a sterilizable leather production process. The process carries out machining sequentially according to the procedures of leather blank sorting, leather blank throwing to be soft, leather blank dust removal, leather blank inside sealing, leather blank bottom coating, standing for passing the night, knurling, throwing to be soft, dust removal, color layer treatment, top coating I/II, standing for passing the night, and vibration to be flat, and sterilizable car leather can be obtained. High-physical-property resin, a feeling agent and a cross-linking agent are screened, a proper ratio is adopted, through matched application of an online 2K mixing machine and a high-level roller coating machine, and application of a multiple poly-carbonization diimine cross-linking agent, wear resistance, sweat resistance firmness, dry and wet rubbing resistance firmness and sterilizing performance of the leather can be improved, and the experiment proves that the leather can be subjected to repeated wiping and sterilizing, and the leather is not damaged. Health of passengers can be effectively protected, needs of a consumer can be met, and the advantage of an enterprise in market competition can be improved.

Description

technical field [0001] The invention belongs to the field of tanning chemistry and technical engineering, in particular to a sterilizable leather production process. Background technique [0002] Cars, as a relatively private and safe means of transportation, are particularly important during the epidemic prevention period, and consumers have increasing expectations for sterilizable car interiors. Leather is the most high-grade automobile interior material. Existing domestic and foreign automobile manufacturers do not have clear standards for whether the corium can be sterilized. If the existing car corium is not properly sterilized, the corium will be damaged. Therefore, this area needs badly a kind of sterilizable leather production technique. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the invention provides a sterilizable leather production process, which realizes the purpose of disinfecting the surface of the leather ...
