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...

A study was conducted to evaluate the quality of the leather from five different cultivars (Red Fleshed, Allahabad Safeda, Lucknow-49, Chittidar, Apple Colour of guava. Leather quality was also observed using three different recipes for its preparation. The study revealed that organoleptic quality (i.e. colour, flavour, taste, texture and overall acceptability) of leather decreased gradually wi...

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...

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% ...

Surface charge and isoelectric point of leather play an important role in the production of leather. However, a precise and rapid method for the determination of leather surface charge and isoelectric point is unavailable nowadays due to the complexity of the structure of leather, especially for chromefree tanned leather. Therefore, it is necessary to develop a quantitative determination method...
