Cow leather treatment process

Abstract

The invention discloses a cow leather treatment process. A hand feeling agent adopted in the treatment process is prepared from, by weight part, 8-11 parts of emulsified silicone oil, 130-150 parts ofparaffin, 50-70 parts of fatty acid, 14-18 parts of an emulgator and 1-3 parts of carbon nano tubes. The cow leather treatment process has the following beneficial effects that the carbon nano tubesare added to the hand feeling agent, after the carbon nano tubes are evenly distributed, slight protrusions are formed on the surface of cow leather, so that light is subjected to certain diffuse reflection on the surface of the cow leather, and a delustering function is achieved; and meanwhile, due to the long tubular characteristic of the carbon nano tubes, the texture of the surface of the cowleather is more natural and attractive. In addition, the two ends of the carbon nano tubes have an adsorption function, the cow leather generally needs to be regularly cared with a caring agent to guarantee the brightness and hand feeling of the cow leather, the carbon nano tubes can adsorb a certain quantity of caring agent, the caring agent is slowly released in the losing process, so that the caring agent is constantly replenished to prolong the existence time of an oil film on the surface of the cow leather, and therefore the service life of the cow leather is prolonged.

Description

technical field [0001] The invention relates to the field of leather products, more specifically, it relates to a cow leather treatment process. Background technique [0002] Cow leather products are very popular and loved by people because of their good texture and appearance. [0003] The Chinese patent whose notification number is CN105925736B discloses a finishing process for forming a full-grain Nappa leather with a full-grain napa leather finishing composition coating embryo. The finishing process includes the following steps: [0004] 1) Soft skin embryos: Put the selected disabled skin embryos into the softening drum, soften them for 1.5-2.5 hours, and then take them out from the drum; [0005] 2) Stretching board: Put the skin embryo treated in step 1) face up on the stretching machine, and the entire skin embryo should be stretched flat without any wrinkles, the clamping distance is 10-15 cm, and the stretching time is 1.5-2.5 hours after removing; [0006] 3) W...

[0020] The hand feel agent has the functions of brightening, smoothing, improving the leather feel, and enhancing the genuine leather feel. In the above-mentioned leather products, the hand feeling agent and the nonionic hand feeling agent are added to the bright paste and the feel paste. In addition, the bright paste also contains water-based varnish, so that The leather surface will be too smooth and shiny and lose its naturalness, which needs to be improved
