Résumé : |
The use of fatliquors is critical to attain the required physical characteristics for leather products. Currently a wide variety of fatliquors are being used in leather manufacturing. There is a lack of information, however, regarding their performance in terms of physical properties of the resultant leather. Such information certainly is very informative for the leather manufacturers to select the right fatliquors to meet quality demands. We have therefore recently conducted a comparison study on the physical properties of leather prepared with various types of fatliquors. Results showed that the type of fatliquor applied in a fatliquoring process does not directly affect the physical properties of leather, instead, the actual concentration of fatliquor will govern the results. Data indicated that a lower Young's modulus induced higher elongation and resulted in increased tear strength. Observation showed an excellent correlation between the softness of leather determined by manual assessment and the Young's modulus. It appears that one of the key functions of fatliquoring is to reduce the initial deformation resistance. Data also showed that the initial strain energy is an improved method to determine the initial deformation resistance, which takes the non-linear viscoelasticity of leather into account and is easier to measure and to define. Therefore the initial strain energy is a better objective method to determine the softness of leather instead of the subjective manual assessment. |
