Chamois leather tanning accelerated by oxidizing agent of Hydrogen Peroxide

Abstract

A weakness of chamois leather production practiced nowadays is its oxidation process taking relatively long time, i.e. nine days to two weeks. The use of an oxidizing agent was reported to shorten the oxidation process of the tanning. Appropriate condition for the tanning needs to be applied in order to improve the process efficiency and to obtain satisfactory quality leather. In this study, the best oxidation times inside and outside the rotary drum of the tanning accelerated by hydrogen peroxide were investigated. The experiment was conducted by tanning of pickled goatskin for 4, 6, and 8 hours oxidation times inside the rotary drum and 1, 2, and 3 days of oxidation times outside the drum. The physical and organoleptic properties of the leathers were tested. The physical and organoleptic properties of the leathers resulted by this study met the quality requirements for the chamois leather. The best conditions for the tanning were oxidation times of eight hours inside the rotary drum and one day outside the rotary drum.

Penggunaan bahan pengoksidasi dilaporkan dapat mempersingkat proses oksidasi pada penyamakan tersebut. Kondisi yang sesuai untuk penyamakan tersebut diperlukan untuk meningkatkan efisiensi proses dan untuk mendapatkan kulit samak bermutu tinggi. Dalam studi ini, diteliti waktu oksidasi terbaik di dalam dan di luar drum berputar pada penyamakan kulit samoa yang dipercepat menggunakan hidrogen peroksida. Penelitian dilakukan dengan menyamak kulit pikel kambing selama 4, 6, dan 8 jam waktu oksidasi di dalam drum berputar dan 1, 2, dan 3 hari waktu oksidasi di luar drum. Sifat-sifat fisik dan organoleptik dari kulit samak diuji. Sifat-sifat fisik dan organoleptik dari kulit samoa yang dihasilkan dari peneltian ini memenuhi persyaratan mutu kulit samoa. Waktu oksidasi terbaik adalah delapan jam oksidasi di dalam drum berputar dan satu hari oksidasi di luar drum berputar.Kata kunci: percepatan, kulit samoa, hidrogen peroksida, waktu oksidasi, minyak biji karet, penyamakan

Chrome-Free Tanning: Effect of a Combination Tannage Based on Mimosa and Biogenic Silica from Rice Husk

“…The increasing public awareness of environmental sustainability has an impact on the leather tanning process. Tanning processes by eliminating chromium are being widely developed using vegetable tanning materials, non-chrome minerals, aldehyde, oil, and a combination of several leather tanning agents [10][11][12][17][18][19][20][21][22][23][24]. This is because chromium compounds have carcinogenic, mutagenic, and very toxic properties [25,26].…”
