Sorption Behavior of Terpenoids on 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...

Sorption of Nitrogen and Water Vapor on Textile Fibers 1

:-Ieas urements were made of the adsorption of nit rogen and water vapor on six purified text ile fibe rs and t itaniu m dioxide. It was found that all of t he fi bers had a relatiYely low capa city for the adsorption of nitrogen as compared with t h c capacity for t h e adsorption of ,,'ater vapor. T he surface area values ranged from 0,31 sq uare meter per gram for nylon to 0.98 square meter ...

Development of Surface-Modified Polyacrylonitrile Fibers and Their Selective Sorption Behavior of Precious Metals

The purpose of this study was to design a powerful fibrous sorbent for recovering precious metals such as Pd(II) and Pt(IV), and moreover for identifying its selectivity toward Pd(II) or Pt(IV) from a binary metal solution. For the development of the sorbent, polyacrylonitrile (PAN) was selected as a model textile because its morphological property (i.e., thin fiber form) is suitable for fast a...

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...
