| titleOfInvention | A method for preparing leather by using waste leather shoe upper leather |
| abstract | The invention discloses a method for preparing leather by using waste leather shoe upper leather, and relates to the technical field of leather. 3) Blending of raw materials; (4) Preparation of fresh shoe upper leather. The invention uses the recycled leather particles of waste leather shoe upper leather as the main raw material, and after pretreatment and supplemented by auxiliary agents, the new shoe upper leather is prepared. , effectively prolonging the service life; at the same time, the preparation cost is low, the recycling of waste leather is realized, and the pollution to the environment is reduced; and the new shoe upper leather can still be recycled after being discarded. After regeneration, new-born shoe upper leather is made, which has the function of loosening the material of the shoe upper leather. The newly-prepared shoe upper leather is dense and has loose apertures, which increases the permeability of the new-born shoe upper leather. |
