skin and leather characteristics of hair-type goats were studied in relation to their sex and age, using 100 randomly-selected skin from goats reared in east west iran. mean weights of skin and leather were 859.2±35.2 and 357.4±16.2 g, and the length and width of leather ranged from 60 to 121 and 41 to 87 cm, respectively. age had a significant effect on the weight and area of skin and leather....

in this work, leather fibers were employed as a component of elastomeric compounds based on nbr, cr and epdm and studied were made on their effects upon curing characteristics and mechanical properties of the prepared compounds. evaluation of curing characteristics of the compounds demonstrated that leather fibers have no considerable effect on initial viscosity and curing time of the compounds...

Hygiene properties of leather shoes, which has great influence on health and comfort, mainly contains air permeability, water vapor permeability, hygroscopicity, heat preservation and antimicrobial ability. The developing situation of test technology on hygiene properties of leather shoes is summarized. Natural leather has excellent hygiene properties for its collagen fibers, each hygiene prope...

vegetable tannins are the main factor of tanning in historical leathers. the identification of tannins in vegetable tanned leathers is not only importantin determining chemical characterization, production technology and structural nature of the leather, but it is also efficient at the evaluation of new vegetable tannins for conservation purposes. previous studies have also shown that chemical ...

the aim followed in the present paper was to evaluate the slaughter body and carcass weights as well as the characteristics of hide and leather in dromedaries (one-hump) and in the crossbred (c. bactrianus×c. droedarius) camels. fourteen camels from each sex (female and male) representing two genotypes at 21 months of age were utilized. slaughter weight, hot and cold carcass weights, dressing-o...

fruit leather is one of dried product with variable production, good marketing and popular consumption in many countries of the world. in this research, the effect of concentration temperature (55-75 °c) and time (20-40 min) and drying temperature (40-70 °c) on the chemical composition (brix, ph, sugars and vitamin c) and the microbial properties of apple leather investigated. the results showe...

Intelligent resource usage is one of the most challenging tasks for the wood-based panels industry. With respect to this issue, leather shavings, derived during leather preparation, are a promising new raw material, as they offer not only high availability, but also potentially enhance material properties such as panel fire retardancy. In order to improve the performance of these emerging panel...

The efficient removal of proteoglycans, such as decorin, from the hide when processing it to leather by traditional means is generally acceptable and beneficial for leather quality, especially for softness and flexibility. A patented waterless or acetone dehydration method that can generate a product similar to leather called Dried Collagenous Biomaterial (known as BCD) was developed but has no...

Tannery wastewater usually contains a high salinity due to the use of sodium chloride (NaCl) in curing and pickling. Although some no-pickle tanning and salt-free pickling technologies were developed, few of them have been widely used due to relatively poor mechanical and bulk properties of the resultant leather. Therefore, the role of NaCl in pickling and tanning should be elucidated in the fi...
