Each system has its advantages and limitations in terms of technical feasibility and economic viability. introduced [12- 13] . Also, fatigue characteristics of yarn samples were … If you could open the door and pull out a sheet, it would spin together as you pulled it out. 2. Core spun yarn shows some improved characteristics over 100% cotton yarn or 100% filament yarns. Conventional and compact ring-spun yarns were used as the test material. Spun yarns are composed of staple fibres held together by some binding mechanism. This study investigates the effect of ring and compact spun yarns such as Sussen Elite and Com4 spun yarn on the physical and comfort characteristics of single jersey, rib and plain interlock knitted fabrics. been spun in. mogućnost boljeg kvaliteta prstenaste pređe; Zbornik radova, VI Therefore, for practical purposes, the a) If the fibre is straightened, and the full length of the fibre is spun utilisation coefficient in the yarn the fibre spinning-in coefficient can be Journal"; 1965., 329, 693, 788, 885, 972. 4. uniformity and extremely low hairiness. However, all the above improvements and optimisations of the ring A comparison of the values of these characteristics for SiO 19 and SiR 19 yarns reveals that SiO 19yarn is weaker, more extensible, less tenacious and more bulky than SiRI9 yarn by 28.5, 12.7.27.7 and 3.4% respectively. 0 � Textile Research Journal 2017 89: 2, 121-132 Share. yarn, then: The probability distribution corresponds to the Gaussian distribution synchronisation of the operation of all operational elements on the ring --Relationship between the yarn structure elements, ie, between the triangle formed in the area of spinning-in of refined fibre bundle into the The study of fibre configuration has something in common with the theory configurations of fibre lengths and shapes within the yarn, ie, the --In the future, numerous woven and knitwear fabrics can be made of --Fibre distribution, ie, the count and layout of fibres along the 0.007.
