Yarn properties can be altered through blending fibres. According to the requirement different properties can be achieved by different blending ratios. Among the different blends cotton and polyester, cotton and wool, wool and acrylic, cotton and nylon, jute and acrylic, cotton and rayon etc are common. Flax and polyester has been a popular blend now-adays and depicts excellent properties than ...
Abstract We report on a non-sharp-corner quarter wave plate (NCQW) within the single layer of only 8 nm thickness structured by Ag hollow elliptical ring array, where strong localized surface plasmons (LSP) resonances are excited. By manipulating parameters ring, transmitted amplitude and phase two orthogonal components well controlled. The difference π/2 ratio 1 is realized simultaneously at w...
The history of silk in the Near East begins in Syria in the Roman period, with cloth and yarn of the Han dynasty imported from China. Some of the cloth may well have been the delicate Chinese gauze, because during the first two centuries A.D. Roman writers were scandalized by its transparency, saying that the wearers were clothed only to be unclothed. Other types, damasks and embroidered silks,...
Electron Lenses built and installed in Tevatron have proven themselves as safe and very reliable instruments which can be effectively used in hadron collider operation for a number of applications, including compensation of beam-beam effects [1], DC beam removal from abort gaps [2], as a diagnostic tool. In this presentation we – following original proposal [3] – consider in more detail a possi...
Yarn hairiness has been an important indication of yarn quality that affects weaving production and fabric appearance. In addition to many dedicated instruments, various image analysis systems have been adopted to measure yarn hairiness for potential values of high accuracy and low cost. However, there is a common problem in acquiring yarn images; that is, hairy fibers protruding beyond the dep...
We developed a novel technique enabling determination of the permeability of electrospun yarns composed of hundreds of fibers. Analyzing the wicking kinetics in a yarn-in-a-tube composite conduit, it was found that the kinetic is very specific. The liquid was pulled by the capillary pressure associated with the meniscus in the tube while the main resistance comes from the yarn. Therefore, one c...
