Investigating the Effect of False Twist Texturing Process on the Color Coordinates Variation of Spun-dyed Polyester Filament Yarns

Correspondence to: Mohammad Amani Tehran email: [email protected] ABSTRACT In this study, color coordinates variation of spundyed polyester filament yarns subjected to the false twist texturing process was investigated. Furthermore, the effect of different processing parameters including D/Y ratio, twist, heater temperature, texturing speed, overfeed, the draw ratio and intermingling process on t...

On the Pressure Behavior of Tubular Weft Knitted Fabrics Constructed from Textured Polyester Yarns

This study attempts to investigate the pressure behavior of tubular knitted fabrics after a long period of time. For this purpose, two kinds of knitted fabric (plain and interlock) with various stitch lengths were chosen and the interfacial pressure and pressure reduction of fabrics after 48 hours were analyzed at different strain percents. The same tests were performed on the same specimens af...

Three-dimensional Texturing Using Lattices

This paper describes a way to perform realistic three-dimensional texturing of ray-traced objects with irregular surfaces. Such texturing has been done in the past with texture mapping, particle systems, or volumetric methods. We propose an alternative to these called a lattice. Lattices work as fast but inexact ray tracers. As long as lattices are used for small objects, though, the inexactnes...

Accelerating Virtual Texturing Using CUDA

Virtual texturing is a promising technique to improve the visual quality of real-time rendering applications such as simulations and games. By selectively loading parts of the texture dataset, virtual texturing allows for higher resolution texturing than possible with traditional texturing techniques. However, virtual texturing also adds a significant overhead to the renderer. First, there is t...

Ion-Solvent and Solvent-Solvent Interactions. X-ray Study of Aqueous Alkali Chloride Solutions

The first neighbour model, FNM, used frequently for the description of hydration has been modified by dropping the assumption that the structure of the "free" solvent is identical with that of the pure solvent. The modified model, FNM2, reproduces the experimental X-ray structure functions of alkali chloride solutions quite well and enables the study of perturbed solventsolvent interactions. Th...
