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...
متن کاملPolarization mode dispersion of spun fibers with randomly varying birefringence.
We show analytically how periodic spinning affects the polarization mode dispersion of a fiber in three different practical regimes that are determined by the values of three length scales: the beat length, the birefringence correlation length, and the spin period. We determine in which limits the spin is effective in reducing the mean differential group delay.
متن کاملA Comparative Study on the Dyeability of Stabraq (Milkweed) Fibers with Reactive Dyes
In this work, raw fibers of a local species of stabraq (milkweed) were scoured, bleached and blended with cotton fibers with a ratio of 75/25 (cotton/stabraq). The improved stabraq fibers, scoured and bleached cotton and the blended fibers were spun into fine yarns and then they were subjected to dyeing with two types of reactive dyes namely, cold brand and high exhaustion brand reactive dye at...
متن کاملProperties of PAN Fibers Solution Spun into a Chilled Coagulation Bath at High Solvent Compositions
In this work, multifilament, continuous polyacrylonitrile (PAN) fiber tow was solution spun mimicking industrial processing at the small pilot scale (0.5 k tow), while carefully altering the composition of the coagulation bath, in order to determine the effect on the resulting fiber shape, density, orientation, and tensile properties at varying points in the spinning process. Novel here are the...
متن کاملPolarization control in spun and telecommunication optical fibers.
We consider the counterpropagating interaction of a signal and a pump beam in a spun fiber and in a randomly birefringent fiber, the latter being relevant to optical telecommunication systems. On the basis of a geometrical analysis of the Hamiltonian singularities of the system, we provide a complete understanding of the phenomenon of polarization attraction in these two systems, which allows t...
