Though an important and chronic source of dyes released to the environment, determination release that occurs during household or industrial washing is usually disregarded. The main scope this study reveal extent dye through washing, understand if modification cotton fabrics with cationic polymers could reduce it. Modified fabrics, dyed Acid Blue 281 (AB) by a mixture reactive Novacron Yellow S...

Polymeric dyes are composed of optically chromophoric groups bound to or into polymers 1 which offer the advantage of allowing a range of physical properties, such as solubility, absorption, migration, and viscosity, that are tunable. They do not sublime, are nonabrasive,and generally have low toxicity. The range of products possible offered by the joining of the fields of polymer chemistry and...

objective: despite sensitive antibody based blood donor screening, infection can be transmitted during window period. therefore sensetive methods bosed on nucleic acid tests (nats) have been considered. the aim of this project was to design a more sensitive method for detection of pcr products and diagnosis of hiv-1/hcv co-infection accurately. materials and methods: after designing specific p...

Acid-fastness is usually defined by the Ziehl-Neelsen technique: staining in carbol-fuchsin, differentiation in HCl-alcohol, and counterstaining in methylene blue.8 As a result, acid-fast substances are red, non-acid-fast materials, blue. Some authors have felt that this property of differential staining resided in one specific type of compound, the mycolic acid type of long-chain fatty acid fo...

Invasive alien plants that damagingly overgrow native ecosystems can be beneficially used to produce natural dyes. Natural dyes are healthier and more environmentally friendly than synthetic dyes, so their use on textiles other products come into contact with humans is desirable. In this study, the possibility of using a dye extracted from purple petals invasive plant Impatiens glandulifera Roy...

Two different kinds of copper nanoparticles (CuNPs) (brown colour and greenish colour) were synthesised by using simple solution route applied exhaust method to achieve multidimensional functionalization on one the most popular cellulose materials e.g., cotton fabric. The CuNPs imparted colours said textile due conditions synthesis localized surface plasmon resonance. Physico-chemical character...
