The Chrome-Tanned Goat Leather for High Quality of Batik

Abstract

ABSTRAKPenelitian bertujuan untuk mengevaluasi kualitas batik kulit yang disamak dengan krom. Penelitian dilakukan secara bertahap dengan tahap pertama bertujuan untuk mengevaluasi natrium silika sebagai bahan pelepas lilin batik pada kulit samak krom. Penelitian menggunakan rancangan acak lengkap (RAL) sebagai perlakuan adalah kosentrasi natrium silika yaitu P1 = 0 , P2 = 2 g/l, P3 = 4 g/L dan P4 = 6 g/L diulang 9 kali. Penelitian tahap kedua bertujuan untuk mengevaluasi jenis bahan warna yang digunakan dalam pewarnaan metode batik pada kulit kambing samak krom. Penelitian menggunakan rancangan acak lengkap (RAL) sebagai perlakuan adalah jenis bahan pewarna yaitu P'1 = asam , P'2 = indigosol, P'3 = napthol dan P'4 = remazol diulang 9 kali. Berdasarkan hasil penelitian penggunaan natrium silika kosentrasi 2 g/L menghasilkan prosentasi lilin yang terlepas sebesar 91,4 % serta tidak menurunkan kualitas kulit samak krom. Jenis bahan warna asam dan napthol memberikan kuat rekat dan kecerahan warna terbaik serta ketahanan cuci, air, keringat, tekuk dan gosok yang terbaik yaitu 4/5 sampai 5 pada skala abu abu. Berdasarkan hasil penelitian kulit kambing samak krom dengan pewarnaan metode batik direkomendasikan menjadi salah satu bahan baku barang-barang kulit.

Study was conducted in two stages, in which the first stage aimed to evaluate sodium silica as batik wax releasing agent on chrome leather. Completely randomized design (CRD) was applied in this study. The concentration of sodium silica was treated as treatments, in which Tl = 0, T2 = 2 g/L, T3: 4 g/L and T4 = 6 g/L. The second stage of the study was aimed to evaluate the type of dye used in batik method dyeing on chrome-tanned goat leather. CRD was used and the treatments were types of dye, i.e. T'1 = acid, T'2= indigosol, T'3 = napthol, T'4 = remazol. In both studies, 9 replicates were applied for each treatment. The use of sodium silicate concentration of 2 g/L resulted in the percentage of release wax of 91.4% and did not degrade the quality of chrome leather. The type of acid dyes and naphthol provided the best adhesion and color brightness and resistance to washing treatment, water, sweat, bend, and rub at 4/5 to 5 on a scale of gray. In conclusion, chrome tanned goat leather with batik dyeing method was recommended to become one of the raw materials of leather goods.

An Evaluation of Simulated Batik Techniques to Chrome Re-tanned Leather Substrates

“…The colophony resin has two types of impacts. Firstly, it increases the melting point of batik wax as the melting point of colophony resin is high (100 °C -150 °C), and secondly, it helps the batik wax from getting frozen quickly and to achieve better pattern line sharpness [9,10]. A high temperature of the wax helps the corium layer of leather to penetrate where removing the wax from the leather becomes difficult [11].…”

“…Continuously using batik wax in a hot state can damage the structure of leather since it brings the temperature near 140 °C. The shrinkage temperature of chrome-tanned leather for laboratory conditions is 96 °C -120 °C and for commercial conditions is 84 °C -100 °C [9,12].…”

The effect of pH and tanning agents on the quality of sheep leather using the ecoprinting dyeing method

“…This causes the number of dissolved flavonoids to increase with the addition of a base. The higher the total dissolved flavonoid and tannin compounds, the higher the compounds are absorbed by the fabric during the dyeing process, thereby increasing the color intensity [11,18].…”

Evaluation of the implementation of Batik-skills training program

“…The development of batik in Indonesia today is impressive. Batik is very popular and growing rapidly in the country since the recognition of batik by UNESCO in 2009 as a world cultural heritage which is originated in Indonesia (Pancapalaga, Bintoro, Pramono, & Triatmojo, 2014). These developments affect and make people realize that batik can create jobs with special skills which are very promising.…”
