Leather craft products, such as belt, gloves, shoes, bag, and wallet are mainly originated from cow, crocodile, lizard, goat, sheep, buffalo, and stingray skin. Before the skins are used as leather craft materials, they go through a tanning process. With the rapid development of leather craft industry, an automation system for leather tanning factories is important to achieve large scale produc...

Idealized edged and non-edged indenters, mimicking canine teeth, were used to puncture thin materials and thick materials. Less force was needed for the edged (triangular in cross section) indenter to penetrate thin Mylar, paper, leather, beetle elytra and turkey skin than the non-edged (circular in cross-section) indenter. Oak, grass and magnolia leaves responded equally to both indenters. In ...

Leather is derived from the hides of skins of animals. It is a remarkably durable, strong and versatile material, which in its various forms has been made into objects ranging from African shields and drums to European saddles and kinky underwear. From as early as 2700 BC until fairly recently leather was also in the forefront of information technology with its use (as skins, vellum and parchme...

Strength is an important property of leather. However the structural basis of strength in leather is not well understood. We have used synchrotron based small angle X-ray scattering to investigate the structure and strength of collagen materials under a variety of conditions. This enables changes in the extent of orientation of the collagen fibrils to be quantified and the internal stress on th...

The development of antimicrobial coatings for footwear components is of great interest both from industry and consumer's point of view. In this work, antimicrobial leather materials were developed taking advantage of chitosan intrinsic antimicrobial activity and film forming capacity. Considering the specificities of the leather tanning industry, different coating technologies, namely drum, cal...

Sample 1: insole from black boot 120 Sample 2: tissue lining leather of black boot 640 Sample 3: insole from red boot 11 Sample 4: tissue lining leather of red boot 1.3 or leather sofas and armchairs manufactured in China. This substance has a wide-spectrum biocide activity and it is contained in paper bags, and progressively it can evaporate and contaminate the leather, textiles, food, cosmeti...

Received: February 25, 2016 Revised: May 08, 2016 Accepted: June 16, 2016 Abstract: Background: The leather industry contributes vast amounts of pollution damaging to aquatic and terrestrial environments. Leather dust is a chromium-contaminated waste produced from the shaving and buffering processes involved in leather tanning. Microorganisms have been investigated for their usefulness in biore...

Animal skin that has been processed to retain its flexibility, toughness, and waterproof nature is known as leather, and the leather industry is New Zealand's seventh largest industry. New Zealand leather is made by processing the skins of animals slaughtered in the meat processing industry, and hence the majority of skins tanned are those of sheep and cattle. Animal skins are converted to leat...

A large case-control study of bladder cancer (2982 cases; 5782 controls) included information about occupational exposure to leather. Occupational histories of exposed white study subjects were reviewed and 150 were determined to have had "true" on the job exposure to leather. The odds ratio estimate (OR) of bladder cancer associated with such exposure in white subjects (n = 8063) was 1.4 (95% ...
