The color of the blends of pre-colored fibers depends on the ratio of each fiber in the blends. Some theories have been introduced for color matching of blends of pre-colored fibers. Most however, are restricted in scope and accuracy. Kubelka and Munk presented the most applicable theory, which is still used in industry. In this work, the classical Kubelka-Munk method for color prediction of a ...

Samples that are going to be used in this research produced such a way the threads 35/2 NM 100% acrylic. The yarns consist of [40% Acrylic (2.75 dtex unrelax), 60% (2.2 relax pilling)] mixing ratios and tow dyeing process has been applied these fibers. In fibre process, by creating 2 groups, light colored fibers, medium-colored dark fibers super dyed were total 8 obtained. Rib plain knit fabric...

Abstract This research is an investigation of the preparation conditions for para-aramid aerogel fibers that are structurally colored by Rayleigh scattering, angle-independent structural color. It well known color has angle dependence colors. However, there currently a desire materials with During fibers’ spinning process, microstructures generated. The effect investigated measuring optical pro...

Macroand crystalline structure, as well as chemical composition of fibers related to various types and sorts of Israeli cottons, both white and naturally colored, were investigated. The differences in structural parameters and chemical compositions of the cotton fibers were evaluated. Samples of cotton of the “Pima”-type had long, thin and strong fibers with highly ordered supermolecular struct...

We report a 61-year-old man with multiple colored skin papules with central crusts in an archiform and linear pattern on his forehead as well as verrucus and hyperkeratotic plaques with central perforation on hands. Histologic examination of the lesions demonstrated a narrow channel of epidermal perforation containing notrophils, basophilic debris and elastic fibers with eosinophilic degenerati...

an algorithm is suggested for implementation of unlimited primaries in two-constants kubelka-munk color matching attempt. allens method for tristimulus color matching which was limited to four colorants in two constant theory, dealt with inversable matrices. by application of the pseudo-inverse, it is not necessary to limit the number of primary colors to four as allen suggested. the suggested ...

Structural colored fiber was fabricated by an isothermal heating evaporation-induced self-assembly method. Under ambient white light illumination, the fibers appear colored due to optical reflectance, which is determined by the lattice constants of the photonic crystals. By controlling the size and layers of the silica nanospheres, the fiber color can be changed.

Structurally colored fiber was fabricated by an electrophoretic deposition method under a circinate electric field. These fibers exhibit structural color, based on the external field-assembly of charged PMMA microspheres on the surface of the electroconductive carbon fiber, with reflectance spectra stretch-tunable in the 430-608 nm, which are determined by the lattice constants of the photonic ...

One of the most important parameters to be controlled during the production of textile yarns obtained by mixing pre-colored fibers, is the color correspondence between the manufactured yarn and a given reference, usually provided by a designer or a customer. Obtaining yarns from raw pre-colored fibers is a complex manufacturing process entailing a number of steps such as laboratory sampling, co...
