Further, the vibration of different elements of the ring spinning machine due to the rotation of spindle, traveller and drafting rollers causes the spinning tension to vary. Interruptions, broken ends and piecing up problems exist because of the yarn breakages. Spinning process is an initial step to produce textile layout such as garments, fabric, home textile and so on. Although ring spinning is the universal spinning system but main limitation of this system is its limited spindle speed which causes lower production rate. Table 1. The fiber supply, usually in the form of roving and having a hank* range from approximately 0.40 to 5.0, is drawn into the drafting system by the rotation of the back rolls. This slide contains rotor spinning system briefly. See our User Agreement and Privacy Policy. 2. The most common measuring method to characterise the dynamic yarn path in the ring spinning process is to measure the yarn tension, where the yarn path is almost straight. Yarn breakages are more numerous as a result of ring traveler friction and yarn air friction. Applications and Uses of Spinning: 1. There is a grid (sieve) at the base which permits only molten liquid to pass through. The ring spinning machine G 37 with the semi-electronic drafting system meets all requirements for an economical yarn production. The ring spinning frame, commonly called the ring, is the conventional spinning system. 11/8/2010 1Prepared by TANVEER AHMED.

Great as a process diagram or to show non-sequential or grouped information. The cotton is then sent to the air conveyed to gin stands where revolving circular saws pull the lint from the saw teeth by air blasts or by rotating brushes. During fiber spinning process in order to achieve cluster, soakage and removal of electrostatic adsorption, glass fiber is coated by in a single layer of textile-based sizing.

The mechanism of yarn … Ring spinning is one of a number of methods for assembling and twisting fibres to form a yarn. But have you ever thought about how they are made? Ans: During the process of spinning, twisted yarn is wound over the spindle cop. 3. Spinning is the The technology maintains two separate strands during the spinning process, and this allows a number of fibre-binding mechanisms to operate before the strands are twisted about each other. The centrifugal force is calculated with the following formula: F C = (m x v 2) / r Ring At present, the Ri­eter, Suessen, and Zinser companies have produced compact ring spinning frames. For the further processes, large package is required for better production rates. See our Privacy Policy and User Agreement for details. During the ring spinning process, the rotation of traveller over the ring and the ring-rail movement cause the spinning tension to fluctuate periodically. Ring spinning machine in the textile industry is an industrial machinery used for spinning process to convert the roving into very fine yarn and then wind it onto bobbins for storage.
