“…Akan tetapi, semakin meningkatnya kepedulian masyarakat pada penyembelihan hewan dan langkanya bahan mentah menyebabkan tingginya permintaan akan kulit yang berkualitas baik (Sundar et al, 2006;Olle et al, 2014). Kulit yang baik adalah kulit yang bersih dan tidak memiliki banyak cacat.…”

“…Perpaduan binder dan pigmen dapat memberikan daya rekat, kelemasan, dan kelenturan pada kulit. Disamping itu, ketahanan gosok cat juga dapat dipengaruhi oleh jumlah resin yang digunakan, semakin tinggi jumlah resin yang digunakan untuk lapisan atas, maka semakin baik ketahanan gosok cat basah, namun ketahanan gosok cat kering berkurang (Olle et al, 2014). Perpaduan resin dan pigmen dalam penelitian ini dapat menghasilkan ketahanan gosok cat tutup yang baik.…”

INTISARIPermintaan kulit yang bermutu semakin meningkat tetapi ketersediaannya semakin menurun. Teknologi pasca penyamakan (finishing) merupakan hal yang dapat dilakukan untuk menutupi kerusakan kulit. Salah satu bahan finishing kulit yang dapat digunakan untuk menutupi cacat kulit adalah pigmen. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan jumlah pigmen pada lapisan dasar terhadap sifat fisik kulit tersamak. Kulit sapi yang sudah disamak ulang diberi perlakuan finishing dengan variasi pigmen 7,5; 10; 12,5; 15; dan 17,5% pada lapisan dasar. Hasil penelitian menunjukkan bahwa pigmen berpengaruh pada penyerapan air selama dua jam dan ketebalan lapisan finishing. ABSTRACT The demand of high quality leather is increasing, but it's availability gradually decrease. Finishing of the tanning process is technology to upgrade the quality of leather. Pigment is one of the materials forfinishing leather that can correcting grain. The aim of this research was to determine the best variation of pigment addition as base coat on physical properties of leather. Retanned cow hide was treated using finishing agent for 7,5; 10; 12.5; 15; and 17.5%

Patent leather is a well-known leather type having a mirror-bright gloss finish and is produced from goat, calf, cattle, and corrected grain crust leathers by the use of patent finishing technique. Due to the emission limitations of volatile organic compounds, now water-based finishing applications are used in leather industry instead of solvent-based systems and still there has been no information in literature to reveal the effect of viscosity on the characteristic properties of patent leathers. Therefore, in the present study, water-based patent leathers differentiated in viscosity were investigated in terms of surface reflectance, tensile strength and elongation at break, to and fro rubbing fastness, distension and strength of surface, heat resistance, flexing resistance, air permeability, colorfastness to water spotting tests and scanning electron microscopy displays prior and subsequent to ageing process. The results of the study revealed that the patent film with 194.46cSt viscosity (S2) viscosity provided comparatively better results.

“…For example, the absorption rate of chromium in the chrome tanning process is only 65–75%, that is, 25–35% of the chromium residue in the tanning spent liquor cannot be absorbed and utilized, causing not only the waste of chromium resources but also serious environmental pollution . So, many researchers are focusing on other methods, such as aluminum tanning, zirconium tanning, titanium tanning, vegetable tanning, and syntan tanning . Among them, aluminum tanning is one of the most important alternative inorganic tanning methods in leather industry (Figure ) owing to its rich mineral resources and nontoxicity …”

Given the toxicity of chrome tanning in leather industry, ecologically compatible alternatives are intensively researched, in particular on the side of aluminum tanning. Herein, the tanning reaction of aluminum with collagen was investigated using microwave irradiation as a new heating method, and the traditional water bath heating (WBH) was used as control. Results from dynamic light scattering and very‐positive differential scanning calorimetry (DSC) analysis reveal that, microwave heating led to larger particle size and increased main denaturing transition temperature of collagen clusters crosslinked by aluminum sulfate. The aluminum‐tanned collagen products obtained under microwave and WBH methods were further compared and characterized using many techniques including circular dichroism, fluorescence spectroscopy, atomic force microscope, and Fourier transform infrared spectroscopy, DSC, and thermogravimetry. Results verified that both heating methods accelerate the crosslinking reaction of aluminum with collagen and increase the crosslinking degrees. The crosslinked products exhibited improved thermal stability, but no change was observed concerning the binding mode of aluminum with collagen. However, compared to WBH microwave heating has a more positive effect on the aluminum‐tanning processes for the improvement of collagen crosslinking processes and product performances, probably due to both thermal and nonthermal effects of microwave irradiation. © 2019 Wiley Periodicals, Inc.
