Twelve ruminally cannulated steers (Angus x Holstein; average initial BW = 533 +/- 3.28 kg) were randomly allotted to one of three treatments (four steers/treatment) to evaluate the use of pretanned leather shavings as a component of a protein supplement for steers grazing dormant intermediate wheatgrass (Thinopyrum intermedium Host). Steers were allotted to one of three treatments: 1) no suppl...

in the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. then the pigmented samples were scanned, and the values of rgb of images were calculated. the artificial neural network (ann) method used to make relation between rgb va...

leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. determining drying characteristics of leather is vitally important so as to optimize the drying stage. this paper describes an analytical way for determination of the drying characteristics of leather. the model presented, is based on fundamental heat and mass transfe...

The present work investigated the possibility to use wet blue (WB) leather wastes as natural reinforcing fibers within different polymer matrices. After their preparation and characterization, WB were melt-mixed at 10 wt.% with poly(lactic acid) (PLA), polyamide 12 (PA12), thermoplastic elastomer (TPE), polyurethane (TPU), obtained samples subjected rheological, thermal, thermo-mechanical, visc...

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....

Ethylene Glycol (EG) is one of toxic and hazardous materials that was used in many industries such as; synthetic fibers, films, antifreeze, resins, explosives, fibers, paper, leather, protective coatings, printing inks and textile. Many environmental problems such as: negative effects on aquatic life, destruction of aquatic ecosystems, soil pollution, reducing the oxygenlevel in the waterabsorp...

Studies of skin wound healing in crocodilians are necessary given the frequent occurrence of cannibalism in intensive farming systems. Air temperature affects tissue recovery because crocodilians are ectothermic. Therefore, the kinetics of skin wound healing in Caiman yacare were examined at temperatures of 33°C and 23°C. Sixteen caiman were selected and divided into two groups of eight maintai...
