Natural dyes re-extraction of raw gambier was used as a dye on cotton yarn. Al2 (SO4)3, FeSO4 and CaO was used as a mordant with post-mordanting method. Dyeing process was done through a few stages; re-extracting of raw gambier, bleaching of cotton yarn, dyeing with gambier solution extract, mordanting with post-mordanting method, and finishing. Dyeing process was carried out at temperature of 30, 50, and 70⁰C with dyeing time 5, 15, and 25 minutes. Analysis of tannin content and particle size was conducted on raw gambier, gambier solution extract and remaining of dyeing solution. Cotton yarn which had been dyed with extracts of gambier evaluated its tensile strength, elongation, shrink yarn, intensity, color direction, and color fastness. The result showed that the hidhest color streght was obtained at 70⁰C dyeing and 25 minutes dyeing time using CaO mordant. Color fastness to 40⁰C washing with the use of CaO modant was good (4). The value of rubbing and light fastness was good until very good (4-5) for all treatments. All treatments with the same mordant shown to have similar of color direction visually, however quantitatively each of sample had a different significant on intensity and direction of colors.ABSTRAKPewarna alam gambir digunakan sebagai pewarna pada benang katun melalui ekstraksi ulang dari gambir asalan. Al2(SO4)3, FeSO4 dan CaO digunakan sebagai mordan dengan metoda pasca mordanting. Proses pencelupan dilakukan melalui tahapan; ekstraksi ulang gambir asalan, pengelantangan benang katun, pencelupan dengan larutan ekstrak gambir, pemordanan dengan metoda pasca mordanting, dan finishing. Proses pencelupan dilakukan pada suhu 30, 50 dan 70⁰C dengan lama pencelupan 5, 15 dan 25 menit. Analisis kadar tanin dan ukuran partikel dilakukan terhadap gambir asalan, larutan ekstrak gambir dan larutan sisa pencelupan. Benang katun yang telah diwarnai dengan ekstrak gambir dievaluasi kekuatan tarik, mulur, mengkeret benang, intensitas, corak dan ketahanan luntur warnanya. Hasil penelitian didapatkan bahwa intensitas warna tertinggi terdapat pada pencelupan 70⁰C dan waktu pencelupan 25 menit dengan menggunakan mordan CaO. Ketahanan luntur warna terhadap pencucian 40⁰C dengan penggunaan mordan CaO bernilai baik (4). Nilai ketahanan luntur warna terhadap penyeterikaan dan sinar matahari adalah baik sampai sangat baik (4-5) untuk semua pelakuan. Semua perlakuan dengan mordan yang sama terlihat mempunyai arah warna yang sama secara visual, namun secara kuantitatif masing-masing memiliki perbedaan intensitas dan arah warna yang cukup signifikan.

Gambir (Uncaria gambir Roxb) Sebagai Pewarna Alam Kain Batik Sutera, Katun, dan Rayon Sofyan Sofyan; Failisnur Failisnur

Gambier (Uncaria gambir Roxb.) is one of main commodities in West Sumatra Province where most of the products are exported in raw gambier form. Many benefits that can be derived from gambier, but there is no diversify of this product. The research was aimed to use gambier as natural dyes in batik fabric and to see the quality of the batik that had been dyed. The study was conducted by varying the type of fabric (silk, cotton, and rayon) and the type of mordant or color fixer namely lime (CaO), alum (Al2(SO4)3), and ferous salt (FeSO4). The fabrics which had been dyed were tested color direction, color fastness of washing, light, rubbing, moreover acid and alkaline perspiration. The results showed that the color direction was brownish with different color darkness depending on the type of mordant used. The results of testing on color fastness were good to excellent averagely. In term of the type of fabric, from the three types of fabric used, silk gave the best result in terms of color fastness of washing and perspiration of acid and alkaline with average test results was good to excellent (scale 4-5). The use of different types of mordant had not given significant effect on testing of color fastness to light and rubbing. ABSTRAKGambir (Uncaria gambir Roxb.) merupakan salah satu komoditi unggulan Provinsi Sumatera Barat dimana hampir sebagian besar produknya diekspor dalam bentuk gambir mentah. Sangat banyak manfaat yang dapat diperoleh dari gambir, namun belum ada hilirisasi produk ini di dalam negeri. Tujuan penelitian adalah menggunakan gambir sebagai pewarna alam pada kain batik dan melihat kualitas kain batik yang telah diwarnai. Penelitian dilakukan dengan memvariasikan jenis kain (sutera, katun, dan rayon) dan jenis mordan atau pembangkit warna yaitu kapur (CaO), tawas (Al2(SO4)3), dan tunjung (FeSO4). Kain yang telah diwarnai dilakukan pengujian arah/beda warna, ketahanan luntur warna terhadap pencucian, sinar, gosokan, dan keringat asam dan basa. Hasil penelitian didapatkan warna ke arah kecokelatan dengan ketuaan warna yang berbeda-beda tergantung jenis mordan yang digunakan. Hasil pengujian ketahanan luntur warna rata-rata adalah baik sampai baik sekali. Bila ditinjau dari jenis kain, maka dari tiga jenis kain yang digunakan, kain sutera memberikan hasil terbaik dari segi ketahanan luntur warna terhadap pencucian, serta keringat asam dan basa dengan rata-rata hasil pengujian baik sampai baik sekali (skala 4-5). Penggunaan jenis mordan yang berbeda tidak memberikan pengaruh pada pengujian ketahanan luntur warna terhadap sinar dan gosokan.
