Abstract Naturally occurring compounds can be utilized as coloring and finishing agents in environmentally friendly textile products. Aronia melanocarpa (Aronia) fruits (berries) are rich bioactive such various form of polyphenolic showing antibacterial antioxidant, thus numerous studies have been actively conducted on berry extract (AE) recent years. However, most natural including pigments ex...

Abstract The purpose of this study was to describe the ecoprint quality silk fabrics with different natural dyes in terms aesthetics motif, and color fastness washing rubbing. This research method is experimental descriptive percentage analysis. Experiments using tunjung alum mordant as well teak leaf ecoprints, Japanese papaya (Cnidoscolus aconitifolius), cherry leaves (Muntingia calabura), Ja...

In the present study copper oxide nanoparticles (CuNPs) were synthesized via simple and eco-friendly green route using black tea extract . Characterization of (NPs) was undertaken. The characteristic absorption peak CuNPs in range (352-355) nm UV–Vis spectrum. Scanning electron microscopy (SEM) transmission (TEM) studies revealed morphological structural character NPs. particle size 25-50 nm. E...

In this paper we present some concepts for sound and fast footstep planning. The soundness is achieved with a two-stage trajectory generation process that uses a smoothing homotopy. The fastness is achieved with swept volume approximations precomputed offline.

Abstract Progressive environmental awareness and legislation regarding the pollutants discharged from textile coloration plants allocate natural colorants in forefront position for dyeing printing of many substrates. In this study, a genuine dye was synthesized by combining diazonium salt m -anisidine with crude extract peanut skin. The melting point (SD) as well its Fourier transform infrared ...

FT-IR spectroscopy is a nondestructive technique that can be utilized for the qualitative characterization of natural dyes and dyed substrates through structure elucidation. This work aimed at dye extract from Beta vulgaris peels pomaces surface analysis optimally dyed-mordanted cotton (cellulosic) fabric using Fourier Transform Infrared (FT-IR) spectroscopy, as well colour fastness tests (ligh...

Double-encapsulated microcapsules (DEMs) were prepared and effectively adsorbed onto the cotton fabric surfaces during impregnation without crosslinking agents to obtain functional fabrics. Specifically, Fourier transform infrared spectrometer (FTIR) confocal laser scanning microscope (CLSM) showed two different molecules (lavender essence dye indigo) encapsulated into simultaneously, with load...

In this research, several series of triarylmethane dyes containing one or more terminal methoxy substituents with a variable tertiary amino groups have been used. These dyes have been applied to different substrates by using various methods including transfer printing and then their fastness properties were measured. These dyes shows exceptionally high light fastness (6-7) on acid modified poly...

Pewarnaan tekstil dapat dilakukan dengan menggunakan pewarna dari bahan sintesis dan alami. Pada dasarnya alami lebih aman digunakan dibandingkan sintesis. Sedikitnya pencemaran merupakan salah satu keunggulan penggunaan Daun alpukat berpotensi sebagai karena mengandung tanin yang cukup besar. Tanin menghasilkan zat warna cokelat kecokelatan pada kain. Akan tetapi, kurang diminati oleh masyarak...
