Embodiment Construction

[0027] The specific processing steps are as follows (taking 1000 grams of frog skin as an example):

[0028] Degreasing: wet the skin with salt, mechanically peel off the meat film, weigh and divide into batches.

[0029] Alkali expansion: water 400%, that is, water 4000 grams, temperature 28 ° C, NaoH solution (30%) 3%, 30 grams, rotate for 20 minutes, stop for 40 minutes, then rotate for 5 minutes per hour, a total of 4 times, replenish water at 22 ° C Water 100%, 1000 grams of water, rotate for 10 minutes, stop the drum overnight. Wash with water for 6 minutes the next morning.

[0030] Deliming: 150% water, 30°C temperature, 2% ammonium sulfate (20 grams of ammonium sulfate), rotating for 35 minutes, washing with water for 5 minutes.

[0031] Enzyme softening: water 100%, that is, water 1000 grams, temperature 35 ° C, 606 enzyme 0.1%, 1 gram, degreasing agent 0.2%, 2 grams, ammonium sulfate 0.3%, 3 grams. Rotate for 60 minutes, check PH=8.2, feel soft, smooth and comfor...

Abstract

A process for preparing the leather from the skin of American frog or bullfrog includes such steps as defatting, expanding in alkali solution removing ash, softening with enzyme, tanning twice, dyeing, and slightly coating for finish which has the procedures of drying in air, natural moistening, beating, stretching, ironing or coating, polishing, and coating oil. Its advantages are high air permeability and water resistance, and good softness.

Description

Technical field [0001] The invention relates to the field of tanning processing, and relates to a method for tanning processing using American frog skin and bullfrog skin as raw materials. technical background [0002] As we all know, cowhide, pigskin, and sheepskin are common leather products, while tiger skin and leopard skin are rare protected animals, and the leather made from them is rarely seen. larger. Therefore, shoes made of cowhide are the most common products. Frogs are small animals, and it is little known to use them to make leather, and frogs are the protectors of crops, and using them as leather products will not be accepted by society. In recent years, bullfrogs and American frogs have entered ponds and restaurants as food, but their skins have been discarded as waste due to their small size. About making leather with frog skin and its processing method, the patent literature has not disclosed yet. Contents of the invention [0003] The present inventio...
