The objectives of this study were to evaluate the light fastness of selected natural dyes (madder, weld and woad) and the effect of some commonly used antioxidants and UV absorbers on the light fastness of these dyes. The photofading rate curves of madder and weld fixed on cotton correspond to type II fading rate curves described by Giles. These results are in concordance with those of Cox-Crew...

This article presents a comparative analysis of the properties cotton yarn spun on aerodynamic compact spinning and open-end rotor systems. Yarn samples with linear density 50 Tex, 37 30 25 20 Tex were both systems using same finisher drawn sliver medium staple which produced by specific mixing. The quality parameters such as mass variation, imperfection index, hairiness, tensile behavior (stre...

In the scope of study, effect fiber blending ratio, yarn count and twist coefficient on migration, packing density diameter cotton/acrylic blended yarns were investigated. The samples with 75-25%, %50-50%, 40-60% cotton-acrylic ratios produced three different numbers; 20/1 Ne, 24/1 30/1 Ne coefficients; 3.5 α, 4 4.5 α. Thus, totally 27 obtained. cross-sectional sliced microtome. image frames cr...

At many marine-terminating glaciers, the breakup of mélange, a floating aggregation of sea ice and icebergs, has been accompanied by an increase in iceberg calving and ice mass loss. Previous studies have argued that mélange may suppress calving by exerting a buttressing force directly on the glacier terminus. In this study, I adapt a discrete element model to explicitly simulate mélange as a c...
