Lipid Role in Wool Dyeing

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...

Dyeing of Indian wool with reactive dyes

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...

Determining Effects of Superfine Sheep wool in INfantile Eczema (DESSINE)

This issue begins with Australian research showing that wearing superfine merino woollen clothing may help manage children with atopic dermatitis. Researchers from the US have reported that patients with hidradenitis suppurativa have changes in the expression of genes encoding enzymes involved in sphingolipid metabolic pathways. Research from Queensland reports on patients treated with diphenyl...

Dyeing in catalase-treated bleaching baths

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...
