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...

In 2013, we raised suspicion that cobalt in leather could be responsible for hitherto unrecognized cases of allergic contact dermatitis. We saw a patient sensitized only to cobalt with clear long-term exposure to cobalt from a leather sofa, and observed resolution of dermatitis following avoidance (1). In 2014,we performed a questionnaire study, which showed a positive and significant associati...

Chromium (Cr) is an important raw material in some chemical industries including paint, pigments, textiles, leather tanning, steel fabrication, electroplating, cement preservation, and canning industries. Once in the environment, Cr exists in various oxidation states depending on pH and concentration. Trivalent [Cr(III)] and hexavalent [Cr(VI)] forms are the most common with Cr(VI) being the mo...

OBJECTIVE To study the effect on the incidence of cancer of exposure to chemicals handled in the leather tanning industry. MATERIALS AND METHODS A case-control study was performed within a cohort of 2487 workers employed for at least six months during the period 1900-89 in three Swedish leather tanneries. 68 cancer cases (lung, stomach, bladder, kidney, nasal, and pancreatic cancers and soft ...

Synthetic dyes are extensively used in many industrial applications like textile, leather and cosmetics. The release of various harmful dyes from these industries into the environment has attracted great attention worldwide in recent years. Biosorption is a very effective dye removal technique from aqueous system. In this research, the biosorption performance of cone of red pine for C.I. Basic ...

The aim of this study was to investigate the effect modern ultrasound sewing on quality synthetic leather garments. This research that has been applied will provide information about technology and help factories move towards these technologies in order auxiliary materials reduce environmental waste results from traditional sewing. includes recent developments construction sewing, paper present...

In the present work an application of fuzzy neural networks for leather quality determination is investigated. An overview of the surface defects characteristics and their significance has been made. For leather quality estimation the most important features are the size and the location of the defects. These characteristics are measured using image analysis and they are used by fuzzy neural ne...

Investigations, which are related to plasma efficiency on the treated leather surface, significant in development of ecologically and economically friendly processes obtaining material desired functional properties. Through pretreatments using different chemical-physical reactions surface layer occurred resulting improved reactivity. In this paper, modification functionalization bovine 1,2,3,4-...

The stringent environmental regulations and compliance regarding leather tanning has compelled industry to seek alternative cleaner ingredients that have the capacity minimize or prevent pollution caused by hazardous chemicals. Practical measures so far involved replacing current use of synthetic chemicals such as chromium salts, dyes, fatliquors surfactants minimizing their usage incorporating...
