Embodiment 1

[0026] Preparation of antibacterial silver-coated cowhide

[0027] Put the industrial ethanol into the metal groove, let the lower half of the rotating suede roller contact the industrial ethanol, and the upper half of the rotating suede roller contact the surface of the cowhide. The ethanol adsorbed on the cloth stick removes the surface stains of the cowhide material; the cowhide material after the stain removal is used as the substrate and put into the sputtering chamber, and pure silver is used as the sputtering target material, and the vacuum is pumped to ensure that the vacuum degree in the sputtering chamber is 2×10 -4 Pa, heat the substrate so that the temperature of the leather material is at room temperature, pass in the working gas argon to ensure that the pressure during sputtering is 0.1Pa, adjust the distance between the substrate and the target to 30mm; turn on the sputtering power supply, and perform sputtering coating , the sputtering power is 30W, and the spu...

[0030] Preparation of antibacterial silver-plated polyurethane leather

[0031] Put the industrial ethanol into the metal groove, let the lower half of the rotating suede roller contact with the industrial ethanol, and the upper half of the rotating suede roller contact the surface of polyurethane leather. When the polyurethane leather passes through the rotating suede roller, Use the ethanol adsorbed on the suede cloth stick to remove the surface stains of the polyurethane leather material; put the polyurethane leather material after the stain removal as the substrate into the sputtering chamber, and use the silver-nickel alloy with a silver content of 80% as the sputtering target material. Vacuumize to ensure that the vacuum degree in the sputtering chamber is 6×10 -4 Pa, heat the substrate so that the temperature of the leather material is 50°C, pass in the working gas argon to ensure that the pressure during sputtering is 5Pa, adjust the distance between the substrate and ...

[0034] Preparation of antibacterial silver-plated PVC leather

[0035] Put the industrial ethanol into the metal groove, let the lower half of the rotating suede roller contact with the industrial ethanol, and the upper half of the rotating suede roller contact the surface of PVC leather, when the PVC leather passes through the rotating suede roller, Use the ethanol adsorbed on the suede cloth stick to remove the surface stains of the PVC leather material; put the PVC leather material after the stain removal as the substrate into the sputtering chamber, and use the silver-aluminum alloy with a silver content of 90% as the sputtering target material. Vacuumize to ensure that the vacuum degree in the sputtering chamber is 4×10 -4 Pa, heat the substrate so that the temperature of the leather material is 40°C, pass in the working gas argon to ensure that the pressure during sputtering is 1Pa, adjust the distance between the substrate and the target to 130mm; turn on the sputtering...

Abstract

The invention discloses a method for preparing antibacterial silver-plating leather. The method is characterized in that the adopted sputtering method is magnetron sputtering and / or radio-frequency sputtering method and comprises the following steps of: removing spots on the surface of a leather material; and then putting the leather material as a substrate into a sputtering room, taking metal silver or silver alloy material as a sputtering target material, carrying out sputtering coating by adjusting technique parameters such as the temperature of the substrate and the temperature of the silver target material in the sputtering technique, and obtaining the antibacterial silver-plating leather. The method for preparing antibacterial silver-plating leather has no pollution, does not changethe performance of the raw leather materials and has high antibacterial efficiency.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and in particular relates to a method for preparing antibacterial silver-plated leather. Background technique [0002] Leather materials include genuine leather (cowhide, pigskin, sheepskin) and synthetic leather (polyurethane, polyvinyl chloride), which are usually used as raw materials for clothing, luggage, shoes and other supplies. The current processing methods for genuine leather leather are: grouping and shaping , weighing, pre-soaking, fleshing, main soaking, lime-coating, hair pushing, weighing, liming, second fleshing, shaving board, re-ashing, washing, degreasing, deliming, softening, washing, Pickling, chrome tanning, drum aging, water squeezing, sawdust rolling, smoothing, trimming, weighing, degreasing, washing, retanning, washing, neutralization, color fixing, oiling for dyeing, color fixing, washing, lapping Horse, drying, trimming, dusting, grading. Synthetic leather...
