5.6.1.2 Twisting Zone It is the second zone and is also very important part of Ring machine in which the strands of fiber are converted into a yarn by the twist inserted. The strength of yarn is depend upon the amount of twist which are given in twisting zone and it is most important than other zone due to required strength of yarn. There are some very important points related to twisting zone below here: Material and type of traveller Wear resistance Lubrication of fiber Smooth running Speed of traveler These above points are very important in yarn quality point of view; otherwise these cause very negative effects and increase the defects in the yarn quality. 5.6.1.3 Winding Zone This is the last section of ring machine in which yarn is wound on the plastic bobbin by the up and down movement of ring rail which is linked to a small motor. It is also very important because the setting of ring rail makes coils of yarn on bobbin in such a way that the Z-twist is not open during winding process. Some points are very important during winding process: Ring rail speed setting Bobbin material No. of coils per inch[48] Fig.22 Diagram of Twisting System Analysis on the Defects in Yarn Manufacturing Process & its Prevention in Textile Industry www.ijeijournal.com Page | 63 5.6.2 Ring Spinning Effects on Quality Ring spinning is the first stage of post spinning in which yarn produced from the roving installed on the hanger on the ring machine. Ring process is the heart of textile plant and there is lot of factors effect on the yarn quality. Speed of machine makes a major role on the yarn quality, as the speed increase of ring machine, the imperfection (Neps 200%, Thick +50, Thin -50) of yarn increase. Hairiness is also affected in ring production process and mainly produced by the movement of burnt traveler and high speed of machine. CV of count is also very important and ring spinning process is the last stage of process where we can reduce the CV of yarn count. Imperfection of yarn count in quality point of view is so important that every customer required this quality standard, that imperfection should be minimum as possible. Ring spinning process also effects on twist variation during manufacturing of yarn. It causes major problems during working in next process.[51] Fig. 23 Diagram of Ring spinning frame tải về 1.28 Mb.
