“…Intensitas warna yang rendah dari pewarna alami telah banyak diperbaiki melalui penelitian sebelumnya diantaranya dengan penggunaan zat mordan (Wanyama et al, 2010;Moiz et al, 2010), suhu dan lama pencelupan (Punrattanasin et al, 2013;Tayade & Adivarekar, 2013).…”

ABSTRAKPewarna alam gambir digunakan sebagai pewarna pada benang katun melalui ekstraksi ulang dari gambir asalan. Al (SO ) , FeSO dan CaO digunakan sebagai mordan dengan metoda 2 4 3 4 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 70°C 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 70°C dan waktu pencelupan 25 menit dengan menggunakan mordan CaO. Ketahanan luntur warna terhadap pencucian 40°C 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.Kata Kunci: Suhu pencelupan, lama pencelupan, benang katun, gambir, pewarnaan ABSTRACT Natural dyes re-extraction of raw gambier was used as a dye on cotton yarn.

In this study, dyeing, fastness and adsorption isotherm characteristics of madder natural dye on the wool and nylon yarns were investigated. Wool and nylon were first mordanted by aluminum sulfate, dyed with natural dye extracted from madder root, and the rates of dyeing and equilibrium times were determined and compared. Nylon, indeed, showed higher dyeing rate and reached equilibrium at comparatively lower times. Adsorption isotherms were identified to be a Nernst-type substrate. In addition, the affinity (Dl°), free energy (DH°) and entropy (DS°) of madder on the wool and nylon were calculated. The obtained results from thermodynamic data indicated that with temperature rise, the partition ratio and the standard affinity significantly decreased. The affinity of madder natural dye to the nylon was gradually higher as compared with wool. Wool, indeed, displayed higher negative values for both enthalpy and entropy changes as compared to those values of nylon. The colorimetric and fastness properties of madder natural dye on nylon were overall superior than on wool.

“…In comparison with synthetic dyes, natural dyes are safer for the environment and health, biodegradable, less toxic, and allergenic (Punrattanasin et al 2013;Rungruangkitkrai et al 2013). Due to the toxic and harmful effects associated with these synthetic dyes, a ban has been imposed by Germany and some other European countries on the use of benzidine dyes in textile garments exported into their countries (Tayade and Adivarekar 2013). Hence, due to the current eco-consciousness, researchers attention has been shifted to the use of natural dyes for dyeing textile materials (Tayade and Adivarekar 2013).…”

Silk fabrics were put through a process of dyeing with natural colorants extracted and used from the bark of the Garcinia dulcis (Roxb.) Kurz. Two padding techniques, pad-batch and pad-dry, were used under different study conditions. The effects of mordant agents used on the fabrics and the natural colorant in the dyeing process, color values, color strength, and the fastness properties of silk fabric were investigated and the results recorded in the following study. The results showed that color values can be changed using various metallic salts as mordants. The fastness properties ranged from fair to very good, while perspiration and light fastness was poor to fair.
