Problems solved by technology

At present, leather products on the market already have the characteristics of excellent performance, novel style and rich colors, but due to the limitation of processing technology, leather products are usually "uniform" in style and color, for example, leather products of the same style and color (such as There will be no obvious difference in the appearance and feel of luggage), and it will be difficult for consumers to reflect their individuality during use, and even embarrassment of "crash". In this case, even very high-end products will have great quality and effect. discount

Embodiment 1

[0036] A leather processing method, comprising the following steps: liming, deliming and pickling, tanning, retanning and dyeing, stretch board drying, finishing, varnish spraying, ironing, softening, etc. for degreased and dehaired raw hides.

[0037] In the above-mentioned process, the described finishing process is as follows:

[0038] Raw material formula of oil wax liquid and cracking liquid:

[0039] The raw material composition (% by weight) of the oily wax liquid: 10% of vegetable oil, 50% of paraffin, 10% of penetrating agent whose active ingredient is alkylphenol polyoxyethylene ether, and 30% of water.

[0040] The raw material composition of the cracking liquid (% by weight): 20% of the cracking liquid, 40% of casein, 5% of penetrating agent whose active ingredient is alkylphenol polyoxyethylene ether, 5% of brightening agent, and 30% of water.

[0041] Finishing process:

[0042] Sprinkle the above-mentioned oily wax liquid on the front of the dry leather base t...

Embodiment 2

[0047] In embodiment 2, the leather processing method is basically the same as in embodiment 1, and the raw material formulations of the oil wax liquid and cracking liquid are changed.

[0048] Raw material formula of oil wax liquid and cracking liquid:

[0049] The raw material composition (% by weight) of the oil wax liquid: 15% of animal oil, 45% of polyethylene wax, 10% of penetrating agent whose active ingredient is aliphatic polyurethane emulsion, and 30% of water.

[0050] The raw material composition of the cracking fluid (% by weight): 25% of the cracking fluid, 35% of casein, 6% of penetrating agent of aliphatic polyurethane emulsion, 4% of brightening agent, and 30% of water.

[0051] Finishing process:

[0052] Sprinkle the above-mentioned oily wax liquid on the front of the dry leather base that is laid flat on the table and dried by stretching boards, and then fold it and press it so that the splashed oily wax liquid at least naturally penetrates into the skin b...

Embodiment 3

[0057] In embodiment 3, the leather processing method is basically the same as in embodiment 1, and the raw material formulations of the oil wax liquid and cracking liquid are changed.

[0058] Raw material formula of oil wax liquid and cracking liquid:

[0059] The raw material composition (% by weight) of the oil wax liquid: 8% of animal oil, 50% of Fischer-Tropsch wax, 12% of penetrating agent whose active ingredient is dioctyl sulfosuccinate sodium salt, and 30% of water.

[0060] The raw material composition of the cracking liquid (% by weight): 15% of the cracking liquid, 45% of casein, 5% of penetrating agent whose active ingredient is dioctyl sulfosuccinate sodium salt, 5% of brightening agent, and 30% of water.

[0061] Finishing process:

[0062] Sprinkle the above-mentioned oily wax liquid on the front of the dry leather base that is laid flat on the table and dried by stretching boards, and then fold it and press it so that the splashed oily wax liquid at least na...

Abstract

The invention provides a leather and a leather product, and a processing method thereof. The processing method comprises the following treatments on a defatted and depilated raw hide material: liming, deashing pickling, tanning, retanning and bottom dyeing, toggling drying, finishing, gloss oil spraying, ironing and milling. The finishing process is as below: spreading liquid wax on the front of a dry hide blank subjected to toggling drying; folding and pressing the blank to infiltrate liquid wax at least to texture of the hide blank; spreading the dry hide blank spread and infiltrated with the liquid wax; rubbing the front of the dry hide blank with the liquid wax; drying; rubbing a cracking liquid; and spraying gloss oil on the hide blank applied with the cracking liquid, and ironing the hide blank at a temperature of 90-115DEG C for 3-15 s. The invention also provides the leather processed by the above method. Through improving the finishing process, the invention endows the appearance of the leather with rich color changes and varied texture, so as to produce different visual and sensory effects.

Description

technical field [0001] The invention relates to leather and leather products and a processing method thereof, belonging to the technical field of leather processing. Background technique [0002] The leather industry is closely related to human life and the development of the national economy, and is a pillar industry of light industry. At present, leather products on the market already have the characteristics of excellent performance, novel style and rich colors, but due to the limitation of processing technology, leather products are usually "uniform" in style and color, for example, leather products of the same style and color (such as There will be no obvious difference in the appearance and feel of luggage), and it will be difficult for consumers to reflect their individuality during use, and even embarrassment of "crash". In this case, even very high-end products will have great quality and effect. discount. With the continuous improvement of consumption concepts, p...
