| Popis: |
Raw bovine leather (hide) undergoes a series of manufacturing processes to obtain a finished leather or semi-finished leather, which as such can last for a long period without damage to the hide. The damage by bacteria in the tannery is almost entirely restricted to the soaking operation, but some damages occur under poor storage conditions after pickling and in a wet stage after tanning. Protection against microorganisms is still needed because long periods of storage in moisture and heat create conditions suitable for the rapid growth of microorganisms, which can cause considerable hide damage. The development of microorganisms causes damage that affects the final quality and usability of the leather. In order to avoid damage, the hide undergoes a process of washing and removing microorganisms, before the tanning process. This paper studies and compares the costs of protection from microorganisms of hide treated with bath containing zeolite and citric acid, after the process of pickling, in relation to the costs of removing microorganisms that occur due to poor storage conditions. The costs are one of the elements for determining economic efficiency. This comparison provides an insight into the costs of these processes and their cost-profitability. |
