A novel pickle less combination tannage based on nano-SiO2 and oxazolidine as a substitute for chrome tanning has been developed. The size and distribution of nano-SiO2 in protein, the hydrothermal stability, the mechanical properties and the antifungal effect of final leather as well as the evaluation of eco-friendly characteristics of combination tannage were investigated. Scanning Electric M...

The present investigation deals with synthesis of new acid dyes from 4-amino-1-(4-sulfophenyl)-3-methyl-5-pyrazolone and phenol derivatives and their metal complexes (Cu (II) and Fe (II)). The phenol derivatives include 4-chlorophenol, 4-nitrophenol, 4-hydroxybenzene sulfonic acid, 2-nitrophenol-4-sulfonic acid, resorcinol and bisphenol A and bisphenol S. The newly synthesized dyes were applied...

Abstract This study aimed to develop eco-friendly bacterial cellulose (BC) bio-leather with improved durability using plant-based proteins, namely soy protein isolate (SPI) and mushroom (MP), which were physically entrapped inside the BC, respectively. The amounts of proteins determined by evaluating tensile strength BC bio-leather, found be 20 wt% 50 for SPI MP, enhanced properties mechanical ...

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...

Despite the fact, world leather industries are built on chromium tannage system, there is a growing interest of metal free tannages (chrome). This primarily owing to rising demand for tanning in industry. The goal this research paper was evaluate influences vegetable tannins materials retannage leather, by using Acacia nilotica ssp Adansonia pods (hydrolysable tannins) and Azadirachta indica ba...

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...
