Titre : Lubrication of leather with polyethylene glycol Type de document : texte imprimé Auteurs : Cheng-Kung Liu, Auteur ; Nicholas P. Latona, Auteur ; Gary L. DiMaio, Auteur Année de publication : 2002 Article en page(s) : p. 355-368 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : One of the problems associated with leather quality is that traditional lubricants ("fatliquors" consisting of oils and surfactants) are known to destabilize collagen fibers. Moreover, because they do not promote the retention of essential moisture, they make the leather fibers prone to over-drying. We have recently applied an aqueous solution of low molecular weight polyethylene glycol (PEG 400) to leather without using any surfactants. The resultant stiffness was characterized by Young's modulus, initial strain energy and acoustic emission methods. Results showed that leather treated with polyethylene glycol solutions showed a significant reduction in its stiffness, indicating that PEG has a lubricating effect in leather. Efforts were also made to understand how factors affect the absorption of PEG into leather. Observations showed that the rate of absorption is not constant; therefore Fick's second law of diffusion, dealing with unsteady state processes, was employed to derive a mathematical model for the absorption rate. The effect of temperature on the absorption rate was also included in the model by incorporating a linear equation into Fick's diffusion equation. The resultant model fits the experimental data very well. It not only depicts the mechanism of absorption, but also predicts the absorption rate as a function of key variables.

Réseaux neuronaux (informatique)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather quality inspection is very important in assessing the effective cutting value that can be obtained from the leather. Current practice involves an expert to inspect each piece of leather individually and detect defects manually. However, such a manual inspection is highly subjective and varies quite considerably from one assessor to another. Often this subjectivity leads to dispute between the buyer and the seller of the leathers and hence attempts are made to automate this. Automatic leather defect classification is a challenging research problem due to the difficulties that arise when segmenting defects from the leather background and determining the characteristics that describe the defects objectively. The present study describes application of machine vision system to capture leather surface images and the novel multi-level thresholding algorithm to segment defective and non-defective regions of leather followed by texture feature extraction to objectively quantify the leather surface defects. A dataset consisting of 90 leather images comprising 20 good leather and 50 defective samples has been used in the study. Experimental results on the leather defect image library database achieved an accuracy of 90% using neural network as classifier, confirming potential of using the proposed system for automatic leather defect classification.

Cuirs et peaux -- Industrie et commerce -- HistoireIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In an overview, from the earliest developments of mechanical aids, to sophisticated processing equipment, the rise of machinery within leather manufacture and the interaction of early leather trades' engineers is discussed. The importance of splitting machine development is emphasised as a precursor to the more general introduction of machinery within leather manufacture. Significant British, German and American leather trades' engineers are identified along with their contributions to machinery development. In Part II the impact of early American designed machinery and the principal role of leading British tanners in bringing patented machinery to the British market is also highlighted.
