What is the purpose of ring spinning?
The ring spinning frame, commonly called the ring, is the conventional spinning system and it transforms the roving from the roving frame into spun yarn using the operations of: Drawing. Twisting.
What is spinning triangle spinning ring?
Spinning triangle is a critical area in the ring spinning process of staple yarn, in which the geometry influences the distribution of fiber and fiber mechanical properties in the spinning triangle directly, and determines the qualities of spun yarn.
What is Rieter Machine?
Rieter is the world’s leading supplier of systems for short-staple fiber spinning. Rieter is the only supplier worldwide to cover spinning preparation processes as well as all four end spinning processes currently established on the market. Furthermore, Rieter is a leader in the field of precision winding machines.
What is ring Traveller or main function?
Functions of ring traveller: It is responsible for winding the yarn onto the cop. It defines Spinning tension. It defines Winding Tension. Traveller imparts twist to the yarn.
What are the spinning pyramids on buildings?
The Eagle Eye is an optical bird scarer that harmlessly deters birds from unwanted areas by making use of light beams reflected from direct sunlight. The reflective pyramid rotates sending the beams around in a menacing pattern.
Why rotor yarn strength is less than ring yarn?
Due to the difference in yarn structure, rotor yarn cannot be compared directly with ring yarn of the same twist level. Rotor yarns require a higher machine twist than ring yarns in order to achieve similar tensile strength levels.
What is conventional ring spinning?
In conventional ring spinning, the zone between the nip line of the pair of delivery rollers and the twisted end of the yarn is called the “spinning triangle.” This represents the critical weak spot of the ring spinning process. In this zone, the fiber assembly contains no twist.
What is rotor spinning machine?
Rotor spinning (commonly called “Open End spinning”) is a process that incorporates spinning and winding operations. With the Open End system, the sliver coming from the draw frame is directly transformed into yarn, wound onto package cones.
What are the benefits of a Rieter ring spinning machine?
Rieter’s innovations constantly provide fresh momentum in ring spinning technology. Long machines coupled with efficient solutions reduce energy consumption and production costs. Modular machine concepts, such as the integrated fancy yarn device, increase flexibility with regard to yarn counts and their respective applications.
Which is the best ring spinning system for spinning?
The Rieter ring spinning system is renowned for energy-saving and flexible production of yarns of the highest quality. No matter whether it is standard yarns of any yarn count, slub yarns or fancy yarns, core yarns or twin yarns, a ring spinning system offers the most flexible solution for every spinning mill.
Which is better a Rieter spinning mill or a mixed spinning mill?
The high productivity of Rieter machines allows a reduction in the number of machines, thus saving a lot of space compared to a process using a “mixed spinning mill”: In the case study mentioned above, the Rieter spinning mill requires five cards, one draw frame and 5% fewer ring spindles than the “mixed spinning mill”.
What makes the ring spinning machine G 38 so special?
The ring spinning machine G 38 with the fully electronic drafting system allows an extraordinary flexibility. Standard and special yarns as well as compact yarns can easily be produced. The individual spindle monitoring system ISM premium reduces about 5% of personnel costs.
