Abstract
Under the alkalescent and normal-temp. conditions, fish skin is soaked with Beta-degreasing enzyme to remove fat, treated with inorganic acid and onganic alcohol to remove deep fat and hematochrome, decoloured with high-energy oxygen, soaked with alkali for expansion and softening, soaked with proteinase, panctreatin and Beta-amylase, and filled with macromolecular oil. The said tanning method can produce soft and high strength fish leather.
Description
The present invention relates to a kind of tanning method for fish skin.
United States Patent (USP) 4379708 and French Patent 72924 disclose a kind of tanning method for fish skin, but do not reach the pliability and the flexure degree of leather with the fish-skin leather that the method that they provide is processed.
The purpose of this invention is to provide a kind of method that becomes softness and the high-intensity leather of tool by tanning fish skin.
Technical scheme of the present invention is design, a kind of tanning method for fish skin, it is characterized in that at slight alkalinity (PH=8.5), temperature is 26 ℃--soak fish-skin with the β defatting enzyme under 28 ℃ the condition, at PH=6.8--7.2, add mineral acid, organic alcohol (1--4 carbochain) is to the degreasing of fish-skin deep layer, the pigment of dehematizing, with degreasing, the fish-skin of dehematizing behind the element is used the mineral alkali degreasing under alkaline condition, with sulfonic acid or Phenylsulfonic acid to the fish-skin degreasing, with the fish-skin behind the oxyhydroxide soak degreasing, under subalkaline condition, fish-skin is decoloured with high energy oxygen [O], soak the softening fish-skin that expands with mineral alkali, softening fish-skin, at PH=8.5--9, temperature is at 25 ℃--use proteolytic enzyme under 30 ℃ the condition, pancreatin, βDian Fenmei soaks, and uses acid soak, uses organic tanning, use the mineral substance tanning, weighting agent is filled, with the following alicyclic organic stuffing than small molecules of 18 carbon, neutralization, acidifying under the condition of PH=2.8 is filled with the more macromolecular oil that 32 carbon are above.
Advantage of the present invention is tanning fish skin to be become the high-intensity fish-skin leather of softness and tool.
Elaborate below in conjunction with embodiments of the invention, at slight alkalinity (PH=8.5), temperature is 26 ℃--soak fish-skin with the β defatting enzyme under 28 ℃ the condition, to remove the fat in the fish-skin, then under the condition of PH=6.8--7.2, add mineral acid, organic alcohol (1--4 carbochain) is to the degreasing of fish-skin deep layer, the pigment of dehematizing, with degreasing, the fish-skin of dehematizing behind the element is used the mineral alkali degreasing under alkaline condition, again with sulfonic acid or Phenylsulfonic acid to the fish-skin degreasing, with the fish-skin behind the oxyhydroxide soak degreasing, under subalkaline condition, fish-skin is decoloured with high energy oxygen [O], soak the softening fish-skin that expands with mineral alkali, softening fish-skin, at PH=8.5--9, temperature is at 25 ℃--use proteolytic enzyme under 30 ℃ the condition, pancreatin, βDian Fenmei soaks, and uses acid soak, uses organic tanning, use the mineral substance tanning, weighting agent is filled, with the following alicyclic organic stuffing than small molecules of 18 carbon, neutralization, acidifying under the condition of PH=2.8 is filled with the more macromolecular oil that 32 carbon are above.
