The recent pandemic scenario has caused demand for green products that have medicinal aspects, as well greener approaches global health. Natural dye from plants, particularly harmal seeds, is an excellent alternative to carcinogenic yellow synthetic dyes. current study been conducted isolate natural colorants seeds in methanolic medium through Gamma-Assisted Extraction (GAE). dyeing variables a...

In the study of color matching in textile dyeing, regression algorithm is used to analyze the nonlinear relationship between the dye concentration and the color data in CIE-La*b* color space of dyeing sample, thereby providing theory basis for establishing mathematical model for textile dyeing. Statistical analysis is conducted on a number of experimental data and the model is tested by actual ...

There is a continuous search for green and sustainable materials processes in textile dyeing finishing. In the current study, wool yarns were grafted with Sodium Alginate-Silver nanoparticles (SA-Ag NPs) consecutively dyed Cochineal or Madder. The weight gain of samples was measured to find optimized SA-Ag NPs initial concentration, Scanning Electron Microscopy (SEM) used study their surface mo...

The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing and dyeing units is often rich in color, containing residues of reactive dyes and chemicals, and requires proper treatment before being released into the environment. The toxic effects of dyestuffs and other ...

The conventional rinsing after bleaching to remove the residual hydrogen peroxide, harmful to the dyes either in solution or on the fabric, was replaced by enzymatic cleaning using catalases. The catalasetreated bleaching liquor was reused for dyeing. Though no hydrogen peroxide was detected after the enzymatic process, the bleaching bath composition caused unacceptable colour changes on dyed f...

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...
