Wool and Synthetic Fibers

Saffron Petals, a by-product for dyeing of wool fibers ‎

The dyeing of wool fibers using saffron petals as a natural dye has been studied for first time in this paper. Saffron petal is one of the by-products of fields which are thrown away after harvesting while they can possibly be used. A series of dyeing formulation prepared with saffron petals and different mordants and the mordant effect on hue, light and wash fastness of dyed fibers were invest...

Properties of radicals formed by the irradiation of wool fibers.

Wool fibers of different sample conditions were irradiated in different atmospheres by (60)Co gamma-rays and were studied by electron spin resonance method (ESR). It was found that a large percentage of the alpha-carbon radicals of polymer main chain were more long-lived radicals. The ESR measurements of irradiated cortex samples of the wool fibers proved that most radicals from the cortex were...

Flexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

Extraction and Antibacterial Activity of Pulicaria Gnaphalodes as a Natural Colorant: Characterization and Application on Wool Fibers

Pulicaria gnaphalodes has various biological activities and is used as an herbal plant in traditional medicine. The major components of the aqueous extract of this plant are flavonoids, terpenoids and phenolic compounds which could be a good candidate for dyeing of wool fibers. In this study, the aerial part of Pulicaria gnaphalodes plant was extracted and used for the colorat...
