Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A simple recycling system was used in the preparation of wet-blue leathers, with the residual chrome tanning liquor being replenished with acid and salt before being used for pickling the next batch of bated hide. Chrome tanning powder was added to the liquor on completion of pickling, to give a total offer of the required amount, with the wet blues thus produced being compared to those prepared by a conventional process. Two series of experiments were carried out to give either "low chrome" (1.8 % Cr203, dry weight basis) or "normal chrome" (2.5 % Cr203) wet blues. Within each series, the initial properties and storage behaviour were unaffected by the use of recycled, rather than fresh, chrome tanning liquors. Low chrome and normal chrome samples displayed similar stability under the storage conditions used, with neither set showing deterioration of the measured properties after the prescribed holding time. Colour measurements on the wet-blues before and after storage showed that the leathers from recycled liquors did not undergo changes greater than those of the control samples, and that between-batch colour differences should not be a problem in practical application. Wastage of chrome tanning salt, and hence concentration of chrome in the effluent, was reduced by approximately 90 % by recycling the residual tanning liquor, rather than discarding it as in a normal process. Overall consumption of chrome tanning salt was reduced by 13 % (low chrome series) and by 24 % (normal chrome series) compared to that of similar, conventional processes.

In this work an attempt has been made to prepare exotic leathers from the bovine ear, which is a solid waste from the slaughterhouse. Ears are the peculiar part of bovine, where a flexible cartilage (Type II collagen) is covered by the skin matrix (Type I collagen). The process for the preparation of the leathers from bovine ears has been optimized. The physical and morphological characteristics of the leathers have been carried out. The air permeability analysis revealed that the air permeability decreased with increase in the cartilage thickness. The processed ear possessed high resistance towards stitch tear and abrasion. The attractive reversible grain pattern along with genuine leather property provides an opportunity to utilize this material as a new source of raw material for leather making.

Ces surfaces acceptent les finitions mécaniques et chimiques classiques et trouvent leurs applications en ameublement et habillement, en particulier dans le domaine du vêtement de sport grâce à leur haute capillarité, leur caractère hydrophile (absorption et élimination de la transpiration) et leur confort.

Résistance à la déchirure
Résistance à la tractionIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Many books spend most of their lives, unused, on library shelves. However, when their owner or the library subscriber wishes to read them they expect the bindings to be in perfectly sound condition. Unlike the majority of products made from leather, bookbindings are expected to last almost indefinitely. That is why when, in the middle of the nineteenth century, it was discovered that large numbers of new bindings were deteriorating rapidly, an explanation was sought. That is also why, over the next century and a half, investigations were made into methods for producing bookbinding leathers with increased resistance to the various agents of deterioration. Care had to be taken, however, to ensure that the materials produced retained the physical characteristics which had made leather the premier choice of bookbinders for hundreds of years. These include ease of paring, easeof moulding, lack of springiness and ability to be tooled.

Température de retraitIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The system acrylic resin+ aluminium (HI) + chromium (III) has been investigated, as the basis of a novel tanning system. In particular, tannages containing very low or zero chromium (III) offers were investigated with a view to finding an alternative to full chrome tannage. High shrinkage temperature was the main aim of these experiments but other parameters were not ignored.
The colour of the leathers were essentially white, even when 1 % chromium (III) was present. There was no loss in thermal stability on soaking for 42 h in water at 30-35°c. Tear strength of fellmongered sheepskin leather was in excess of the 1976 GERIC guidelines for garment leather. Light fastness was better than 6 on the Blue Wool Scale.Note de contenu : - RESULTS : Tannages with increased polymer/reagent offer - The colour of aluminium tanned sheepskins - Tannages with polymer reagent, Aluminium and chromium - Tannage of whole sheepskins - Tannages with increased Aluminium offer
