“…Grafting of vinyl monomers onto leather and hide powder has been reported [1][2][3][4]. Graft polymerization is initiated by different initiation systems including Ce (IV) ions [5], potassium permanganate [6], potassium persulphate [7] as well as redox systems such as potassium persulphate -ascorbic acid [8] and persulphate/bisulphate [9,10].…”

Chrome tanned leather was grafted by poly (glycidyl methacrylate) (L-g-PGMA) via emulsion polymerization technique and the grafting yield 26%. Epoxy content of the grafted leather samples was 69.4 mmol/100gm. The obtained L-g-PGMA samples were impregnated in different dibutyl amine solutions using amine/ epoxy molar ratio ranging from 0.5 up to 2.5. The obtained samples were assessed through varying nitrogen analysis, infrared spectroscopy, thermogravemetric analysis (TGA) analysis and scanning electron microscope. It was found that the nitrogen content of the treated leather samples increases by increasing the dibutyl amine concentration up to amine/ epoxy molar ratio of 2 after which it decreases. The water absorption, tensile strength and elongation (%) as well as hardness of the modified leather samples were studied and compared with the unmodified one. The colour strength values of dyed leather samples with acid dye were found to increase by grafting or by increasing the amine/epoxy molar ratio up to a value of 1.0 after which it decreases. On the contrary, the colour strength value of dyed leather sample with reactive dye sharply decreases after grafting with poly (glycidyl methacrylate). Samples grafted with glycidyl methacrylate and treated with dibutylacrylate amine exhibit increased colour strength which is directly related to the nitrogen content of the sample.

“…Two most common FUs which applied in previous studies were kg and m 2 of finished leather. Because the thickness of the final product is also important, thickness was also included in the selected FUs (Chen et al, 2014). For the final comparison m 2 of finished leather was used as the main FU.…”

“…), and Taiwan (Chen et al. ), but these studies have focused on chromium‐tanned leather and adopted dissimilar functional units and system boundaries (hence the results of these studies are not capable of comparison). Therefore, limited or inconsistent information about differences in the environmental performance of chromium‐ and vegetable‐tanned leather is available to researchers and to the general public.…”
