Production method of automotive interior leather with refreshing and comfortable fragrance, low emission and low atomization

Abstract

The invention relates to a production method of automotive interior leather with refreshing and comfortable fragrance, low emission and low atomization. The production method is characterized by comprising the following steps: liming, softening, tanning, retanning, fat liquoring, drying, bottom coating and top coating, wherein the step of liming is characterized by completing the processes of liming, saving hair and removing hair through combination of a biological ablation mode and combined action of a low quantity of liming aids and light alkali substance; the step of softening is characterized by adding 0.5% of a biological softening enzyme preparation OPORONON into a delimed leather rotary drum, reacting and rotating for 30-50 minutes; the pH value of the whole softening process is controlled to be 8-9; then the steps of washing with water and controlling water after the leather is softened to meet the requirements; the salt-added acid-leaching reaction is carried out to control the pH value to be 2.8-3.0; the temperature of bath liquid is lower than 27 DEG C. The production method of the automotive interior leather is capable of removing and preventing the influence of bad smell caused by rot of leather products because of bacterial actions, helping the leather to retain good hand feeling and elasticity, simultaneously enabling the leather body to be compact, sufficient intoughness and high in rebound resilience.

Description

technical field [0001] The invention belongs to the technical field of new materials, in particular to a method for producing automobile interior leather with refreshing fragrance, low emission and low atomization. Background technique [0002] Due to the rapid development of my country's automobile industry, consumers have higher and higher requirements for the comfort and appearance of automobiles. In terms of design, production and improvement of the quality of automobile interiors, automobile manufacturers will continue to improve the airtightness of the car compartment and the new decoration level of the interior facilities in response to consumer requirements, making it easier for the air pollutants to accumulate in the car. Narrow air quality and bad smell in the car have become an industry problem, and it has increasingly attracted the attention, attention and complaints of the whole society and consumers, and it ranks first in the quality complaints, and directly af...
