Leather Technology: A Series Of Reports On Duan Zhenji Leather And Footwear Science And Technology Award

2020 Zhenji leather Research and application of low atomization fatliquor for high grade automobile cushion leather

In recent years, with the improvement of people's living standards, the demand for high-end cars is increasing. The interior upholstery of high-end cars, especially the cushion, is made of leather Car seat The demand for leather products has an obvious upward trend. Because the interior environment of the car is easy to be exposed to sunlight and the temperature is very high, if the content of volatile oil and VOC in automobile cushion leather is too high, it will volatilize and adhere to the automobile glass, which will affect the sight and cause danger. Therefore, the automobile cushion leather has high requirements on leather fatliquor, and the atomization value should be less than 2mg.

At present, most of these fatliquoring agents are imported products, and there is no such kind of products with better performance and stability in China. Qihe Lihou Chemical Co., Ltd Seizing the market opportunity, starting to develop "special low atomization fatliquor for high-grade automobile cushion leather" and promoting the localization of leather chemicals can not only broaden the market, but also improve the popularity of enterprises in the market, and promote the development of enterprises and the sales of other products.

The innovation points of the project are as follows:

(1) multiple fatliquor components are optimized and compounded, and the fatliquoring effect is complementary to each other, which improves the fatliquoring effect and saves the amount of fatliquoring agent.

(2) the chemical modification of fatliquoring components increases the active group and the binding force with leather fiber, so as to improve the absorption rate, reduce the volatile components and reduce the atomization value.

(3) the particle size of emulsion is small and the absorption effect is good. It can reduce the liquid ratio in the process of fatliquoring and save the water consumption, thus saving the cost and reducing the discharge of wastewater.

(4) there is no "three wastes" in the production process, which meets the requirements of environmental protection.

At present, the low atomization fatliquor has been mass produced, and the market is still in promotion. Due to the high requirements of automobile cushion leather, leather enterprises have not completely changed their concepts. They are worried about the risks of using domestic products. They prefer to use foreign products. Only a few customers with stable relationship are trying to use them. The company timely changes its thinking and tries to optimize the compounding method to produce such products Compound with existing products, so as to improve the sales of low atomization fatliquor.
