properties of these materials. Investigations of dye adsorpThe effects of tannic acid and Rhodamine B on the zeta potention on the materials and the electrical and thermodynamic tials and surface free energy components of polyester fabric (Daproperties of the fiber/solution interface are fundamental for cron 54, Style 777) were studied. Knowledge of these parameters understanding the dyeing mec...

The production of textiles is the second most polluting industry worldwide. Non-biodegradable petroleum-based dyes, toxic compounds to fix colors on textiles, and release large quantities these colorants complicated agents into neighboring environment are key causes this issue. On other hand, natural dyes chemicals prevalent in nature with eco-friendly properties. These recyclable biodegradable...

Critical quality conlrol parapeters are discussed foitarious dye classes, equipmentxocesses, and substrates. AlsoYiagnostic tests and repair pro:edures are presente...

Anthocyanins are natural dye substances that provide attractive colors from red to blue. However, large quantities of Anthocyanins have been found in wastewater from soaked black beans, resulting in environmental pollution. The utilization of theses wastewaters would therefore be an effective way of reducing environmental pollution, and the water could be used to dye silk fabric, displaying...

Tracheotomy is one of the oldest surgical procedures, and it is a life-saving procedure to overcome upper airway obstructions. While congenital causes play an important role in pediatric tracheotomy indications, upper airway edema and obstruction due to anaphylaxis rarely require tracheotomy. Allergy can cause life-threatening acute edema by anaphylactic reactions in the respiratory tract. Henn...

Bleaching of organic cotton fabric can be done with hydrogen peroxide in which Catalase, a non-toxic, environmentally friendly biocatalyst is used to remove the residual H2O2 in a cost effective way for the better improvement of the cellulosic fabric properties. Enzyme treated organic cotton fabric was dyed with a natural dye obtained from orange corolla tube of Nyctanthes arbor-tristis flower ...

In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

There's little study-based evidence of anyone getting gray hair from dyeing his or her hair over and over again. However, some studies have suggested that heavy use of hair dye might cause cancer [2] in some people (both in people who are dyeing their hair, and in colorists whose livelihood depends upon providing the coloring process). The connection to cancer needs more research, but it's enou...
