Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : An acrylic resin nano-size latex whose colloidal particle size was about 20nm and solids content about 25% was prepared by a high solids content semicontinuous microemulsion copolymerization. The experimental product was employed in retanning drop [bottom] splits of pigs aiming to reinforce the leather. The offer of cross-linking agent and functional monomer were varied in the copolymerization experiment and their effect on the reinforcing function was investigated. The effect of colloidal particle size and dosage of nano-size latex on the reinforcing function also was verified.
The particle size of the latex was tested with a laser particle size analyzer, and the composition of the copolymer was analyzed by infrared spectrometry. Multifunction material test equipment was used in the physical testing of the retanned leather.
The result of the experiment showed: when the dosage of divinylbenzene (DVB) was 1.2% and the dosage of acrylic acid (AA) 0.8%, the reinforcing performance was the highest. When the colloidal particle size decreased from 64.2nm to 16.3nm, the reinforcing effect was also enhanced.
The tensile strength increased by 68%, and the tear strength improved 44% after the drop splits of pigs were retanned with 2% acrylic resin nano-size latex (with respect to the shaved wet blue weight). The effect of the dosage of sodium lauryl sulphate (SLS), n-pentanol (PA), ammonium persulfate (ASP) and AA on the colloidal particle size was also studied.Note de contenu : - EXPERIMENTAL DETAILS : Materials - Synthesis

Produits de nourriture du cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : With the implementation of Carbon Neutralization strategy, it is urgently needed to develop low-carbon leather chemicals through replacing petrochemicals with biomass-based raw materials in leather industry. To solve the problems existing in the leather fatliquored by the biomass-based fatliquoring agents made from vegetable oils with high unsaturation, such as poor storability, unpleasant odor, yellowing and possible formation of hexavalent chromium, the strategy was put forward, improving the oil saturation through the double bonds addition reaction with halogen to solve the abovementioned problems resulting from the poor oxidation resistance of oil, and increase the binding ability of the oil with leather fibers and endow the leather with flame-retardant simultaneously. In this paper, the methods of modified rapeseed oil by bromine addition and its fatliquoring and flame-retardant properties were studied. The results showed that the bromine addition reaction of rapeseed oil was easy to proceed and the iodine value of the modified oil decreased almost linearly with the added amount of bromine. The binding and antioxidant properties of the oil and the physical properties of the fatliquored leather were significantly improved with the increase degree of bromination modification. Furthermore, above mentioned unpleasant odor, yellowing and hexavalent chromium formation problems were effectively solved when the iodine value of modified fatliquors was reduced to 31 g I2/100 g. Additionally, brominemodified rapeseed oil could endow leather with good flame-retardant properties and the fatliquored leather was changed from combustible to flame-retardant material with the increasing amount of bromine in the oil. The limit oxygen index (LOI) increased from 24% to 31%, the flame combustion time decreased from 127.0 s to 4.3 s, and the flameless combustion time decreased from 28.5 s to 0.0 s. This study provided an effective way to develop biomass-based and low-carbon fatliquors based on natural unsaturated oils.

Pore-size of the matrix has significant impact on the diffusion rates of the substances involved. The determination of pore-sizes and related parameters is necessary for an understanding of the diffusion phenomena in leather processing and related techniques. There are some limitations in existing pore-size measurement techniques for natural fibrous materials like leather; hence there is a need for development of novel techniques with non-influencing character on structure of materials like leather. In this regard, a capillary flow porosimetry technique for pore-size measurement has been applied to two types of leather viz., full-chrome crust leather (FCC) and vegetable-tanned crust (VTC). By utilizing the capillary flow porosimetry technique, important pore-size parameters such as smallest, largest and mean pore-size plus porosity and average Darcy permeability have been determined. The respective values are 0.04p, 0.93p, 0.13p, 59.1% and 0.027 respectively for FCC leather and 0.04p, 0.67p, 0.11p, 49.9% and 0.021 for VTC leather. The results indicate that FCC leather has greater porosity compared to VTC leather; possibly due to chrome tanning providing less filling effect compared to vegetable tanning.

PicklageLe picklage consiste à faire absorber à la peau en tripe une quantité importante d'acide, en présence de sel neutre (NaCl) pour réprimer le gonflement que provoquerait l'acidité du milieu.
TrypsineLa trypsine (EC 3.4.21.4) est une enzyme digestive du suc pancréatique qui a pour rôle de digérer les protéines.
Elle est synthétisée par le pancréas sous forme de trypsinogène (proenzyme inactive), puis stockée dans les vésicules enzymatiques des cellules acineuses d'où elle est excrétée au moment de la digestion. L'activation du trypsinogène en trypsine est le résultat de l'hydrolyse d'un propeptide sous l'action de l'entérokinase ou par un effet d'autoactivation de la trypsine par elle-même. La cholecystokinine-pancréozymine active la sécrétion des enzymes (donc de la trypsine) dans le suc pancréatique.
La trypsine est une endoprotéase qui hydrolyse les liaisons peptidiques dans lesquelles un acide aminé basique (Lys-|-Xaa ou Arg-|-Xaa) engage sa fonction acide (sauf dans le cas où l'acide aminé suivant (schématisé ici par "Xaa") est une Proline). Elle coupe en C-terminal de ces acides aminés. En d'autres mots, elle transforme les chaînes polypeptides en chaînes protéiques plus courtes pour permettre la digestion. Efficace à pH 7,5 - 8,5, elle est inactivée et digérée en quelques heures à pH neutre (=7) dans l'intestin.
La trypsine participe à l'activation d'autres enzymes comme l'alpha-chymotrypsine par coupure hydrolytique de la chaîne polypeptidique du chymotrypsinogène.
Cette enzyme sert également lors de la 2e semaine du développement embryonnaire humain. Elle est sécrétée par le trophoblaste afin de digérer la zone pellucide entourant le blastocyste. Ce phénomène s'appelle l'éclosion.Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Traditionally, universally used pelt bating technologies rely on the application of trypsin, neutral and alkaline microbial proteases but suffer from complicated operation, limited bating efficiency and unsatisfactory leather performance. Therefore, devising a new pelt bating approach to achieve high bating efficiency and excellent leather performance has always been wished for by the leather industry. To pursue this goal, years of persistent research work enabled us to develop a novel approach for pelt bating by means of acidic proteases in pickling process. Initially, basic enzymatic characteristics and bating effectiveness of several typical acidic proteases in pelt pickling medium were investigated; then, the bating effectiveness through the quantitative characterization of protease activity of the optimal acidic protease was compared with that of the conventional bating enzyme. The results indicated that all of the selected acidic proteases had good salt-tolerance and exhibited optimum activity at pH 3.0–4.0. The novel pickling-bating method based on microbial origin acidic protease L80A led to an outstanding performance on pelt bating at the dosage of 150 U/mL of collagenolytic activity. The bating effectiveness of acidic protease L80A was comparable to and even better than that of trypsin BEM due to its moderate proteolytic ability. Moreover, the deep and even penetration of acidic protease in the pelt permitted it to produce soft, organoleptically stable and overall better quality crust leather than that of the conventional trypsin bating method. Additionally, pelt bating was performed along with the pickling process without extra inactivation and washing operation, making the bating operation more efficient, economical, and environment friendly. Results had made us to conclude that this cutting-edge acidic proteases based pickling-bating method could be the first step/ way forward to replace the decades-old traditional pelt bating technology.

Experiments with 1%, 2%, 3%, 4% and 5% L-ascorbic acid addition were performed on the finishing layer of the finishing application. L-ascorbic acid was not added to the control group and processed according to the standard method. After these processes, color measurement analyzes were performed on Konica Minolta CM 3600d spectrophotometer. In order to investigate the effects of L-ascorbic acid on other performance properties of leather, light fastness test according to TS 1008 EN ISO 105-B02 (2001 TS EN ISO 11640 2001) and dry rub fastness test according to standard method were performed. The results of the study were statistically evaluated according to the NCSS (Number Cruncher Statistical System) method. As a result of the research, it was observed that L-ascorbic acid gave a pearly pink color to the leathers. It was found that the dry rubbing fastness of the leathers treated with L-ascorbic acid improved. In the light fastness tests, the results of the experimental group leathers were recorded better by the blue scale.
