“…The use of high power would result in thermal damage and deterioration of the keratin hydrolysate as the power of the microwave increased from 450 to 900 W, the maximum color strength and lower lightness at 450W. 32,33 The extraction time is one of the main factors in the extraction acquisition Table 4, which shows the effect of extraction time on the color strength of the dyed fabric. The result revealed that the ideal extraction time of keratin hydrolysate was 12 min.…”

Viscose dyeing is one of the major pollutants of water due to the large amount of salt in the dyeing effluent. This study paves the way for improving environmentally sustainable wool waste and highlights a promising invaluable application through salt-free viscose dyeing. The keratin hydrolysate (KH) was obtained using microwave (MW) alkaline hydrolysis then applied on the viscose fabric in the finishing bath formulation using the pad-cure technique. The rheology of the hydrolyzed wool fibers and the amino acids composition using high-performance liquid chromatograph (HPLC) was estimated; furthermore, the fourier transform infrared spectroscopy (FTIR) of freeze-drying keratin hydrolysate was evaluated. Microwave-assisted keratin hydrolysis leads to the breakdown of peptide bonds and the release of low molecular weight proteins and peptides. The color strength (K/S) of the dyed post-finished viscose fabric increased 75% compared with that dyed by conventional technique. FTIR, scanning electron microscopy (SEM) and energy disperse x-ray spectroscopy (EDX) demonstrated and confirmed the effective finishing of keratin hydrolysate. The tensile strength and elongation of viscose fabric did not change after finishing with KH, while the air permeability improved and the light fastness properties for the modified viscose fabrics.

Dyes are widely used for various manufacturing processes. However, the high use of synthetic dyes has resulted in pollution and health problems. To overcome this problem, one way that can be done is to return to using natural dyes. Natural dyes can be obtained from various plants, one of which is the Indonesian mangrove plant (Rhizophora mucronata). This research has succeeded in extracting natural dyestuffs from mangrove bark using the microwave-assisted extraction method. Mangrove wood extraction was carried out with solvents, namely distilled water and ethanol 96%, which was optimized based on the ratio of sample mass to volume of solvent and extraction power. The results showed that qualitatively the mangrove extract contained tannins, flavonoids, and quinones as compounds that gave chocolate color. The color resistance of mangrove extracts is very strong in textiles under alkaline conditions. Based on the results of extraction optimization, the optimum conditions were obtained at a ratio of 0.067 g/mL of 96% ethanol at 380 watts of power, with a yield percentage reaching 53.053%. Keywords: extraction, mangrove wood, microwave Zat warna banyak digunakan untuk berbagai proses manufaktur. Namun, tingginya penggunaan zat pewarna sintetis mengakibatkan pencemaran dan masalah kesehatan. Untuk mengatasi masalah tersebut, salah satu cara yang dapat dilakukan adalah kembali menggunakan zat warna alami. Zat pewarna alami dapat diperoleh dari berbagai tumbuhan, salah satunya tanaman bakau Indonesia (Rhizophora mucronata). Penelitian ini telah berhasil melakukan ekstraksi zat warna alami kulit kayu bakau dengan metode microwave-assisted extraction. Ekstraksi kayu bakau dilakukan dengan pelarut yaitu akuades dan etanol 96% yang dioptimasi berdasarkan rasio massa sampel–volume pelarut dan daya ekstraksi. Hasil penelitian menunjukkan bahwa secara kualitatif ekstrak kayu bakau mengandung tanin, flavonoid, dan kuinon sebagai senyawa pemberi warna coklat. Ketahanan warna ekstrak kayu bakau sangat kuat pada bahan tekstil pada kondisi basa. Berdasarkan hasil optimasi ekstraksi, kondisi optimum didapatkan pada rasio massa sampel-volum pelarut sebesar 0,067 g/mL dan daya sebesar 380 Watt sehingga diperoleh persentase yield mencapai 53,053%.

“…In this concern, advanced technologies such as ultrasonic and microwave has been presented as an energy efficient and environment friendly [16][17] developments for natural color extraction and receive the significant consideration of researchers due to their potential advantages like faster and solvent free extraction [18] over conventional solvent extraction methods [19]. Recently, authors found that ultrasonic [20] as well as microwave extraction [21] as an advanced and efficient techniques for extraction. Ultrasonic waves rupture the cell membrane by means of forcibility acting shockwaves created with the formation and collapsing of bubbles resulted in improved percolating of color constituent and hence extraction efficiency.…”

Extracție eficientă cu ultrasunete și microunde a colorantului organic Henna pentru vopsirea materialelor textile sintetice din poliester cu proprietăți superioare de rezistență a culorii Tehnică de extracție eficientă din punct de vedere energetic și ecologică pentru extracția colorantului organic Henna a fost propusă pentru vopsirea materialelor textile sintetice din poliester, cu proprietăți de rezistență ridicată a culorii, pentru a satisface cererea mondială de procese și produse eficiente din punct de vedere energetic și ecologice, în comparație cu metodele convenționale de extracție cu solvent. Metodele de extracție cu ultrasunete și microunde au fost ulterior analizate și optimizate, în ceea ce privește timpul de extracție și raportul de flotă. Pentru aobserva efectul pH-ului asupra vopsirii naturale a poliesterului cu colorant Henna, vopsirea a fost efectuată la două valoridiferite ale pH-ului. Tehnicile cu ultrasunete și cu microunde au extras semnificativ colorantul Henna, într-un timp mai scurt decât metoda convențională de extracție cu solvent. Rezistențe mai mari ale culorii au fost înregistrate prin extracția cu ultrasunete și microunde a colorantului Henna la vopsirea materialelor textile din poliester. Cuvinte-cheie: colorant natural Henna, extracție cu microunde, vopsire organică, material textil din poliester, extracție cu ultrasunete An efficient ultrasonic and microwave assisted extraction of organic Henna dye for dyeing of synthetic polyester fabric for superior color strength properties An energy efficient and 'green' extraction technique for extraction of organic Henna dye has been proposed for the dyeing of synthetic polyester fabric with high fastness and color strength propertiesto fulfill the world's highest demand towards energy efficient and 'green' processes and products and compared with conventional solvent extraction methods. The ultrasonic and microwave extraction methods were further analyzed and optimized in terms of extraction time and liquor ratio.To observe the effect of pH on the natural dyeing of polyester with Henna dye, dyeing were carried out at two different pH. Ultrasonic and microwave techniques noticeably extracted Henna dye with in less time than conventional solvent extraction method. High color strength and fastness properties were observed with ultrasonic and microwave extracted Henna dyeing of polyester fabrics.
