Azo dyes are widely used colorants in consumer products such as leather, textiles, agriculture, cosmetics and in laboratories as indicators. This paper describes the synthesis of some novel azo dyes starting from 3-nitro salicylic acid. The synthesized dyes were investigated for their redox potentials, evaluated for their dying ability on cotton fabrics, resistivity against the fungi growth on ...

In this work, microwave irradiation was used to extract two dye plants (Quercus ithaburansis Decaisne and Rubia tinctorum L.) natural cotton. Using (MW) energy, the extraction time for these dyeing organic cotton fabric were optimized. The colouring compounds analysed in extractions dyed fabrics by reversed-phase high-performance liquid chromatographic method coupled with a photodiode array det...

Irradiation Microwave was used in fixation of pigment prints on cotton fabrics with a colour strength parameters comparable the previous research obtained case thermo-fixation procedures. However printing pastes introduced to fabric via screen methods. The printed subjected irradiation microwave for different periods time at power. Results both covered and uncovered ranges from 3.8 10.70 1.66 8...

In this work, a facile and inexpensive one-step sonochemistry irradiation method was developed for the fabrication of SiO2 nanoparticles functionalized with octadecyltrimethoxysilane and their in situ incorporation into cotton fabrics. The double sides of as-prepared fabrics show both superhydrophobic and superoleophilic properties simultaneously with a high water contact angle of 159 ± 1° and ...

The influence of the bentonite content (1, 3, 5 wt%) on mechanical properties lightweightcotton (C), polyester (P) and polyester-cotton (P/C 50/50) fabrics was investigated. Starch used asa water-insoluble binder for coating fabrics. Bentonite nanoparticles were obtained by repeated hydration,decantation evaporation water dispersion. particle size determinedby XRD method using Debye-Scherrer eq...
