Textile composites are widely used in automotive, naval, and aerospace industries. The variation of the topology of the textile structure will affect the performance of the composite. The yarn micro-geometry is determined by 1) the textile process, such as weaving, braiding, etc. and 2) the composite forming process, such as vacuum bagging, resin transfer molding, etc. In this paper, we present...

SHANKAM NARAYANA, VIVEK PRASAD. Novel Method for Dynamic Yarn Tension Measurement and Control in Direct Cabling Process. (Under the directions of Dr. William Oxenham, Dr. Abdelfattah Seyam and Dr. Edward Grant). Yarn tension control is an important parameter for quality and efficiency in textile processes. It has a significant influence on productivity in various processes such as winding, twis...

Cotton knitted fabrics were manufactured with different yarn types (conventional ring spun yarn and torque-free ring spun yarn) with different fibre types (combed cotton and combed Supima cotton) and yarn fineness (Ne30 and Ne40). These fabrics were then dyed with three types of dye (reactive, direct and sulphur dye) with three dye concentrations (0.1%, 1.0% and 5.0% on-weight of fabric (owf)) ...

High volume instrumentation (HVITM) measurement is a primary and routine tool of providing fiber properties to cotton researchers. There have been considerable studies designed to derive yarn quality from acquired fiber quality data by various means, including HVI. There is also of desired information about the comparison of yarn quality within a cotton cultivar or among the cultivars, as such ...

the nylon and nylon/lycra yarns were coated with electrically conductive polymers such as polyaniline and polypyrrole, via chemical polymerization process. electrical conductivity of the coated yarns was measured at variousstrain levels using two-point probe technique and their strain sensitivities were studied. the results showed that, electrical conductivity of the coated yarns decreased with...

Abstract Simulated galaxy distributions are suitable for developing filament detection algorithms. However, samples of observed galaxies, being limited size, cause difficulties that lead to a discontinuous distribution filaments. We created new catalog composed continuous cosmic web with no lone The core our approach is ridge filter used within the framework image analysis. considered galaxies ...
