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...

Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...

In this study, we explore the dyeing properties of extract sappan wood natural dye for coloration wool yarn to find potential use dyed in development eco-friendly textiles. Different characterizations were used know chemistry and its interaction with metal salts wool. Interestingly, found that salts, which are called as mordants reference unmordanted sample, play an important role fixing molecu...

Lyocell-type fibers often exhibit a high tendency to fibrillate under wet abrasion conditions, and fibrillation must be diminished for better quality of the textile product. In this study, we propose green route cross-linking regenerated cellulose using citric acid (CA) 1,2,3,4-butanetetracarboxylic (BTCA) prevent from fibrillation. We investigated influence process conditions additives on fibe...

The main drawback with microorganism's development on fabrics is associated the maintenance of hygiene and fabric deterioration. In this present investigation a trial has been made to produce an attractive vibrant textile eco-friendly antimicrobial dyeing by marigold, natural resource. Tagetes erecta universally recognized as Marigold remarkable source carotenoids lutein, grown lawn plant. Now ...

Ultra-violet protection and self-cleaning action of nano zinc oxide (ZnO) and titanium di-oxide (TiO2) with acrylic binder has been assessed on the cotton fabric using pad-dry-cure method. Different precursors, such as zinc acetate and titanium tetrachloride have been used to synthesize nanoparticles. Zinc acetate is synthesized into nanoparticle by wet chemical technique and titanium tetrachlo...

Reactive dyeing is the most widely used method for cellulosic fabrics in textile industry. In this study, it was aimed to reduce environmental impact caused by use of high salt during with reactive dyestuffs. context, a quaternary ammonium based chemical cationization cotton fabrics. The usage amount cationizing agent and flake caustic determined experiments as 50 g/L 17 g/L, respectively. Conv...

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.

Worldwide, 45 million tons of waste cotton textiles are produced annually, which 75% is burned and buried, leading to serious environmental pollution. In this study, a method for directly preparing colored regenerated cellulose fibers (CRCFs) from dyed textile (DCTW) was demonstrated. The tensile strength CRCFs reached 226 MPa, equivalent that commercial viscose fibers. exhibited excellent colo...
