Abstract

The invention provides vegetable tanned upper leather. The vegetable tanned upper leather is prepared by using a method comprising the following steps of a wet process, a dry process, and a post-treatment process. According to the vegetable tanned upper leather, after being subjected to dry-process veneering based on polyurethane bayes, the upper leather is printed through a water-based treatment agent, so that a beautiful visual effect is achieved; through an embossing depth study, the granular sensation on the surface of leather can be achieved to the maximum extent; through the treatment on water-based materials on granular bulge parts subjected to embossing, the touch feeling of the vegetable tanned upper leather is most similar to or exceeds that of the leather; through a temperature, humidity and time-controlled kneading process study, the handfeel softness and the floss density of the vegetable tanned upper leather can be most similar to or can exceed those of the leather.

Description

technical field [0001] The invention belongs to the field of leather, in particular to planted kneaded shoe upper leather. Background technique [0002] In recent years, countries around the world have strengthened their awareness of environmental protection, and developed countries have intensified their environmental protection requirements for synthetic products. The synthesis of solvent-based polyurethane requires more solvents, is more toxic, and has greater pollution to the environment. The trade barriers to environmental protection of synthetic leather and the increasingly high quality requirements of consumers have contributed to the development of a new generation of synthetic leather products. The inevitable trend of market development. [0003] At present, synthetic leather is more and more widely used in daily necessities and industrial products, but the light perception, feel, layering, and overall physical properties of synthetic leather can not reach or excee...
