Estimation of pigment magnitudes in synthetic leather by using scanner and artificial neural network
In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...
متن کاملModification of Microfiber Synthetic Leather Base and Model by Collagen
Modified by the pretreated model with collagen under the crosslinking effect of glutaraldehyde, the moisture absorption of modified samples increased by 26.34% and 42.6%. The test results of SEM, AFM and DSC show that there was coating on the fibers modified with collagen, and the relative average roughness of the modified fabric decreased. Modification with collagen also affected the thermal p...
متن کاملLeather
Leather is derived from the hides of skins of animals. It is a remarkably durable, strong and versatile material, which in its various forms has been made into objects ranging from African shields and drums to European saddles and kinky underwear. From as early as 2700 BC until fairly recently leather was also in the forefront of information technology with its use (as skins, vellum and parchme...
متن کاملTaguchi-based optimization of adhesion of polyurethane to plasticized poly(vinyl chloride) in synthetic leather
In this investigation, the effects of formulation and processing factors on the adhesion between polyurethane (PU) and plasticized poly(vinyl chloride) (pPVC) layers was studied using the Taguchi method for experimental design. Among the many factors, nine parameters were screened and tested at two or three levels, taking advantage of the Taguchi L27 orthogonal array. The factors studied were P...
متن کاملAssessment of Biodegradability of Synthetic Tanning Agents Used in Leather Tanning Process
---The goal of this research was to assess the biodegradability of two synthetic tanning agents (syntans), Phenol condensation product and Nitrogen containing resin using Respirometry. The evaluation involved the analysis of oxygen uptake rate (OUR), profiles by respirometry. The study was conducted with different syntan concentrations of 50mg/L, 100mg/L, 150mg/L and 200mg/L. The oxygen uptake ...
