Sturgeon leather production method and sturgeon leather produced using same

Abstract

The invention provides a sturgeon leather production method and a sturgeon leather produced using same. The sturgeon leather production method comprises the following steps of: 1) pretreating a sturgeon leather raw material with a bone deck by means of cleaning, soaking and degreasing; 2) sequentially performing primary softening, pickle softening and tanning to the bone deck of the pretreated sturgeon leather by means of cleaning, soaking and degreasing, so that the bone deck is softened; and 3) treating the sturgeon leather with the softened bone deck by means of neutral retanning, dyeing, greasing and drying to obtain the sturgeon leather with the softened bone deck after the bone deck is treated by means of the primary softening, the pickle softening and the tanning. The sturgeon leather produced by the method is soft and ventilate, and has good tear-resistant performance and buckling-resistant performance, so that the special bone deck of the sturgeon is firmly adhered to the surface of the leather without falling off, the bone deck can be bended at 45-90 degrees without breaking off, and each bone deck is distinct in gradation, natural in decorative pattern, beautiful and fashionable.

Description

technical field [0001] The present invention relates to a method for tanning sturgeon skin and the sturgeon leather produced according to the method, in particular to a method for producing sturgeon leather by performing processes such as preliminary softening and tanning of the bone deck of the sturgeon skin, And Sturgeon leather with softened bone deck made in this way. Background technique [0002] Sturgeon (Acipenser sturio Linnaeus, Latin literary name: Acipenser sturio Linnaeus, English name: Common sturgeon) is an existing ancient biological population. Sturgeon has a strange body shape, a plow-shaped head, a lower mouth, a crooked tail, and a five-element large bone deck on the back of the body ( Bone plate), large body (0.5-7 meters), and long life. Wild sturgeon are distributed in Heilongjiang, Yangtze River, Yangtze River to Pearl River and coastal areas in my country. The breeding and domestication of sturgeon has been carried out in most parts of my country an...

Yet the bony deck that has on the skin of sturgeon skin is relatively hard, utilizes the disclosed method of CN 1710111A to not make the bony deck of sturgeon skin soften, and the method disclosed in CN 1710111A is mainly applied to the sturgeon skin after removing the bony deck. It is processed for tanning, and the resulting leather does not have the beautiful pattern of the bone deck unique to the sturgeon skin, and it cannot make the best use of the bone deck of the sturgeon.
