Tannage au chromeIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Conventional methods employed in leather processing subject the skin or hide to wide variations and alterations in pH. This contributes to an increase in COD. TDS. chlorides, sulphate and other minerals in tannery waste waters.
A process sequence has now been explored to limit the pH range in leather processing from 4.0 to 8.0.
In the previous investigation, development of a dehairing process at pH 8.0 was demonstrated. In this investigation, an appropriate tanning system with adequate opening—up at a pH range of 4.0—8.0 has been investigated. The required fibre opening was achieved by means of lyotropic rather than osmotic swelling. The conditions for chrome tanning were standardised without conventional pickling.
A sequence of operations, viz., enzyme assisted zero-lime dehairing, lyotropic swelling for fibre opening and pickle-less chrome tanning provides leathers matching the functional performance of commercial upper leathers. The modified process leads to a substantial environmental benefit as observed in the reduction of chemical oxygen demand and total solids when compared to conventional processes. The process explored appears to be economy viable.Note de contenu : - EXPERIMENTAL PROCEDURES : Optimisation of opening-up of fibre bundles - Standardisation of tanning system - Selection of tanning system - Comparison of efficiency of selected tanning system with conventional tanning process

AldéhydesUn aldéhyde est un composé organique, faisant partie de la famille des composés carbonylés, dont l'un des atomes de carbone primaire (relié au plus à 1 atome de carbone) de la chaîne carbonée porte un groupement carbonyle.
L'aldéhyde le plus simple est le formaldéhyde (ou méthanal), aussi appelé formol lorsqu'il est en solution aqueuse.
Un aldéhyde dérive formellement d'un alcool primaire (oxydation) dont le groupement hydroxyde -OH est en bout de chaîne et se forme suite à l'enlèvement de deux atomes H d'où le nom "alcool déshydrogéné" ou aldéhyde.

Température de retraitIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Exploring the application of natural biopolymers in leather manufacture is a need of the hour to achieve sustainability. The present research work explores the possibility of using modified biopolymer nanoparticles as a tanning agent. Starch, a polysaccharide with high functionalization, is converted into Nano Bio Aldehyde (NBA) through periodate oxidation as water-in-oil microemulsion method. The synthesized product was characterized by its physico-chemical nature. The prepared NBA shows an aldehyde content of 85%, which endorses its application as a tanning agent. Experimental leather trials were carried out to assess the tanning efficacy and found that NBA tanned leathers show a shrinkage temperature of 90°C. Physical characteristics of the experimental leathers were found to be 24 N/mm2 and 90 N for tensile and tear strength, respectively. The study provides a holistic understanding of modified biopolymer as a nano tanning agent to manufacture leather. Note de contenu : - MATERIALS AND METHODS : Materials

Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Dyes based on synthetic formulations are being widely used in the leather industry. However, it is known that many aryl amine dyes are banned due to their carcinogenic nature. Environmental concern leads one to look for dye products based on natural resources, which have several advantages like biodegradability, less toxicity, etc. The basis of this approach is to achieve an eco-friendly dyeing process with the use of iron salts, which give rise to various colors on reacting with vegetable tannins. Goatskins have been tanned with Cr-Fe tanning salt and striked with different vegetable tanning materials like wattle, chestnut, myrobalan and quebracho at various concentrations. Colors like brown, bluish black, deep black and grey shades have been developed. The color shades obtained have been quantified by reflectance measurements and compared with the visual assessment data. The strength and bulk properties are not significantly altered by increasing the concentration of various vegetable tannins from 1 to 5%. However, treatment with 5% wattle decreases the strength properties of the leathers appreciably due to its heavy filling nature coupled with prior filling using co-filling syntans.

Poudre de cuirIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Three reference materials for As, Cd, Co, Cu, Hg, Ni, Pb and Sb - 8 inorganic elements in leather powder were developed with relatively low, middle and high concentrations. The reference materials were prepared by adding an appropriate concentration using industrial process. The concentration range of the three levels is within the +/- 200% of the limited value in the China statute Safety Technical Specifications for Children's Footwear (GB 30585-2014). By using 16 units with duplicate analysis, it was shown that the samples were enough to demonstrate the homogeneity of these candidate reference materials. The statistical results from the stability test, also showed no significant trends in both short-term stability test for one week at 40°C and long-term stability test for 23 months. This set of reference materials, were used for more than two certification methods - including isotope dilution inductively coupled plasma mass spectrometry (ID-ICP-MS), inductively coupled plasma mass spectroscopy (ICP-MS) and inductively coupled plasma optical emission spectroscopy (ICP-OES). The combined relatively standard uncertainties of the reference values were estimated by considering the uncertainties of the analytical methods, homogeneity and stability. The range of the expanded uncertainties of all the elements is from 3% to 5%. The certified reference materials (CRMs) are primarily intended for use in the calibration and validation of procedures for the determination of inorganic elements in leather or similar leather samples.
