In this paper the fuzzy comprehensive method is given which is based on the leather’s lastometer property under different loads. Fuzzy analysis theory is used to evaluate the softness quantitatively, scientifically and objectively.

The evaluation of leather handle character using neural networks / Huang Xun in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 91, N° 4 (07-08/2007)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 91, N° 4 (07-08/2007) . - p. 172-174 Titre : The evaluation of leather handle character using neural networks Type de document : texte imprimé Auteurs : Huang Xun, Auteur ; Zhang Xiaolei, Auteur ; Wang Mengxiao, Auteur ; Yong Zhang, Auteur Année de publication : 2007 Article en page(s) : p. 172-174 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leathers handle and character has been evaluated and classified using an artificial neural network (ANN). Experimental mechanical parameters correlated to elasticity, softness, fullness and extensibility were obtained. The feed-forward neural network used provided accurate modelling between the input parameters, bend constant (Kb) ; compression index (Kc); lastometer coefficient (Kl) ; attenuation constant (αb); attenuation speed constant (K ́) and the output parameter (leather’s handle and graded character). Although only a small number of experimental data were used in training the neural network, the results obtained are comparable to the results of evaluations done by the traditional method.
