Problems solved by technology
Static electricity will bring certain harm to the human body, and it will also affect the performance and quality of products where static electricity occurs. For example, the static electricity in high-end cars, airplanes, and computer rooms will not only cause operators to suffer electric shocks, but also cause cars or Instruments and remote controls in the aircraft failed, and the computer command system was out of control

Abstract
The invention discloses anti-static cattle hide upper leather and a preparation method thereof. The process is conducted by the adoption of the combination method of wet dyeing and finishing anti-static treatment and dry finishing anti-static treatment; in the wet dyeing and finishing work section, 6.0% of anti-static agents are added for anti-static treatment after dyeing and fat-liquoring procedures, and a drum is stopped to stay the night; in the dry finishing coating procedure, conductive fillers are adopted to be doped in a coating material to conduct anti-static treatment on a coating. The physical and chemical property of the anti-static cattle hide upper leather manufactured through the technology can meet the national standard, the volume resistivity is 103 omega m, the number of flesh side adsorption paper pieces is four, and the anti-static grade is four.
Description
technical field [0001] The invention belongs to the technical field of functional leather. Background technique [0002] Antistatic leather, also known as antistatic leather, refers to leather with antistatic function. Static electricity is a kind of electric energy existing on the surface of objects, which is a phenomenon produced by the partial imbalance of positive and negative charges. Static electricity will bring certain harm to the human body, and it will also affect the performance and quality of products where static electricity occurs. For example, the static electricity in high-end cars, airplanes, and computer rooms will not only cause operators to suffer electric shocks, but also cause cars or Instruments and remote controls in the aircraft failed, and the computer command system was out of control. In production and life, the use of leather and its products is very common, and static electricity hazards will inevitably occur during use. Therefore, the product...
