Biodamages and Protection of Leather and Fur

Abstract

The paper presents the information about biodamages and protection of leather and fur. The contributors put a special emphasis on rawhide microflora, putrefied hide microflora, effect of prior operations on bioresistance of leather, interesting facts, fur skin structure and properties changes by microorganisms and the methods of leather preservation against microorganism impact.

Thermal and mechanical analysis of pickled and tanned cowhide: Effect of solar radiations

“…This also explains why the temperatures corresponding to the peaks in storage modulus for tanned hide were slightly higher than for pickled hide (Figure ). These results agree with those by Pekhtasheva et al ., where it was observed that elastic properties of collagen increases with tanning. The temperature corresponding to the second peak of storage moduli for tanned hide was greater than that for pickled hide.…”

“…It improves the thermal stability by increasing the melting temperature, shrinkage temperature, or denaturation temperature . The results agree with those reported by Pekhtasheva et al . In both pickled and tanned hides, nonirradiated samples had the highest melting temperature compared to solar‐irradiated samples.…”

“…The collagen, which majorly constitutes dermis, self‐organizes to form bundles or a meshwork that determines the mechanical strength, the elasticity, and the geometry of the leather . Tanning forms new cross‐links in the collagen that had otherwise been broken by the acids and alkalis used prior to tanning . However, collagen makes the outdoor applications of cowhide materials sensitive to natural environmental conditions such as solar ultraviolet radiations, oxygen, water vapor, and heat .…”

An Overview of the Main Trends in the Creation of Biodegradable Polymer Materials

“…Not all bioplastics are biodegradable and decompose faster than synthetic polymers [16]. e main methods for preparing biodegradable polymers are as follows [17]:…”
