Résistance à la déchirureIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : To be able to reduce cost in the automotive or furniture upholstery trim, manufacturers are often inclined to use coated or finished splits in the panels that are partially or fully hidden. The flesh split, spearated at the liming stage or the tanned stage, is processed with the intention of being used as high-performance split. The dyed crust split is then roller ans spray finished as a finishde split. Alternatively, a transfer/foil coating (coated split) is used on a surface that will become the new 'grain' surface. If the split is to be finished, a pre-ground and grounding coat may need to be applied first. The pre-ground,or ground, coat takes the role of helpming adhesion, binding the nap down, filing the 'grain', and ensuring consistency of absorbency.
The main physical properties that a high-performance split must have include :
- High tear strength
- Emboss retention
- Surface and nap cleanliness
- No organge peel
- Good finish adhesion
- Tear strength
The side that ends up being the 'grain side' is decided by the tanner and is decided by the cleanliness and the thickness of the split. For normal thickness leathers, the fibre strength increases as one moves from the grain through the bulk of the corium (to a peak) and then decreases into the flesh, due to the fibre size and angle of weave. The angle of weave is lower in the flesh and grain, overall, and the fibre diameter is smaller than the corium fibres.Note de contenu : - Fig. 1 : The anisotropic influence of the hide structure on tear strength

Vernis en phase aqueuseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Patent leathers are currently fashionable. When demand is strong, as is the case today, tanners and finishing units that have the expertise to produce leather finished with a well proven patent coating system will have experienced and overcome the many application and performance difficulties that are associated with this type of finish.
The original patent leather finishing process that was developed and introduced into commercial manufacture during the latter part of the ni neteenth century used a linseed oil based lacquer coating. This process produced finished leather having the desired high gloss, "plastic" surface. Physical performance was adequate initially but the finish hardened on ageing, resulting in a tendency to crack. Technology has moved since Chose days but the so-called "genuine patent leather" produced today is finished using solvent dilutable polyurethane solutions that are cured using isocyanate based crosslinkers. Water based products are now available that will produce what are termed "wet look" finishes. These products are relatively easy and safe to apply and overcome many of the difficulties and hazards associated with the well-tried solvent based systems. However, they still fall slightly short on the depth of transparency and lustrous gloss level when compared with that of the solvent based systems.
Whilst it is the final top coat applied to the leather that determines its gloss level, there are many additional factors that determine the quality, physical performance, consistency and look of the finished leather.Note de contenu : - Making patent leather

Vapeur d'eauIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : est results of finished leathers are presented in this paper. Varying proportions of acrylic resin and collagen hydrolysate were used as binding agents. The hydrolysate was produced from waste chromium-tanned hide by means of acid hydrolysis. Sorption, desorption and water vapeur permeability were assayed and softness of leathers finished with mixes of varying collagen hydrolysate contents was determined. The testing has demonstrated that collagen hydrolysate in the finishing mixes improved the hygienic properties of finished leathers (increasing absorption, desorption and water vapour permeability). On the other hand leather softness declined a little.
It has been demonstrated that a new leather finishing mix containing protein hydrolysate recovered from chrome shavings can be proposed.Note de contenu : - Production of collagen hydrolysate
