A novel chitosan-based biopolymer dye possessing antibacterial properties was synthesized by reaction of O-carboxymethyl chitosan and Acid Red GR. The synthesized materials were characterized by Fourier transform infrared spectroscopy (FTIR), degree of substitution (DS), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG), X-ray diffraction (XRD), water solubility test, anti...

Nowadays, textile processing based on biotechnology has gained its importance in the view of stringent environmental and industrial safety conditions. The use of protease enzymes in protein fibers to improve some physical and mechanical properties is particularly interesting. In this research, wool yarns were first treated with different concentrations of protease enzymes in aqueous solution in...

Globally, there is growing demand in natural colourants from plants the food, cosmeceutical and pharmaceutical fields. Generally, among various categories of secondary metabolites, carotenoids, anthocyanins, phenols are significant plant-based pigments. Coloured pigments possess remarkable anthocyanin related to anti-oxidant, anti-inflammatory anti-metastatic features. The major objective this ...

Large amounts of water, synthetic dyestuffs and chemicals are used in the wet processes textile finishing, at end these processes, liquors containing chemical substances create a waste load. For this reason, it is great importance to develop new wet-finishing that use less chemicals. purpose, layer-by-layer deposition method (LbL) was research as an environmentally friendly, sustainable can be ...

This paper describes the participation of the TUB-IRML group to the MediaEval 2014 Visual Privacy task. We present a method for privacy protection of individuals in surveillance videos. In order to achieve this, our method obscures both shape and appearance of identity-related regions through blurring and color remapping. The intelligibility is preserved by displaying edges and anomalous events...
