Abstract

The invention discloses a preparation method for preparing antibacterial leather, belongs to the technical field of leather manufacturing, and particularly relates to a preparation method for antibacterial leather. The method sequentially comprises the following steps of: pretreating: spraying an antibacterial agent on the pretreated leather or textile fabric; soaking: soaking the rough machiningleather in an activating agent solution, and then soaking the rough machining leather in an antibacterial solution for repeated soaking and drying; modifying: smearing the obtained leather with an auxiliary agent with a formaldehyde and peculiar smell removal function, standing and drying, brushing the oxidized leather with a mixed coating agent, drying in a drying oven, then soaking in absolute ethyl alcohol for heating, soaking and cleaning, and repeatedly drying and soaking and cleaning to obtain dried leather; and laminating, namely laminating the baked leather in a laminating machine withthe pressure intensity of 240-270Mpa, taking out the leather, and softening the leather at normal temperature to obtain the antibacterial leather. The invention is harmless to the environment and human body, has wide application range, and has no harm to human, leather products and natural environment when in use.

Description

Technical field [0001] The invention belongs to the technical field of leather production, and in particular relates to a preparation method of antibacterial leather. Background technique [0002] Leather is animal fur that is not easy to degenerate and rot after dehairing and tanning. It is mainly made of cowhide, pigskin, horse skin and other animal skins as raw materials. Its hand feel is smooth, soft, plump, and elastic. Softness, tear resistance, tortuosity resistance and other properties are deeply loved by people at all stages. [0003] At present, the production processes of artificial leather and synthetic leather at home and abroad are mainly divided into dry polyurethane leather making process, wet polyurethane leather making process and waterborne polyurethane process. These methods use a large amount of toxic and harmful chemical solvents such as dimethylformamide (DMF), toluene, and methyl ethyl ketone in the production process, which will cause great harm to the env...
