Crystallite orientation in wool 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...

Clothing Fibers As Evidence--A Study of the Frequency of Occurrence of Blue Wool Fibers

Using Eggplant Skin as a Source of Fruit Waste Colorant for Dyeing Wool Fibers

Today, natural colorants are emerging globally due to their safety and environmental friendly characteristics. Natural dyes have been employed in dyeing Persian carpet piles for many years. Food and fruit industry wastes are one of the main sources of colorants which can be employed for textile coloration. Eggplant (Solanum melongena), a member of the family Solanaceae, is used in food recipes....

Conjugated polymer chain and crystallite orientation induced by vertically aligned carbon nanotube arrays.

We report a method for controlling the orientations of conjugated polymers in the active layer of organic thin-film transistors (OTFTs) by annealing the film at the melting temperature in a vertically aligned multiwalled carbon nanotube (VA-CNT) template under various load pressures. Poly(3-hexylthiophene) [P3HT] molecules are effectively aligned in the melting state annealing at 240 °C for 30 ...
