Open-end spinning is a technology for creating yarn without using a spindle.It is also known as break spinning or rotor spinning. The principle behind open-end spinning is similar to that of a clothes dryer spinning full of sheets.
Open end spinning is also known as break spinning or free fibre spinning. In this process the fibrous material is highly drafted to separate out the individual fibres. The individual fibres are subsequently collected onto the open end of the yarn. This is rotated to twist the fibre into the yarn structure to form a continuous strand of yarn. This is wound onto a bobbin to form the yarn package. The twisting action occurs simultaneously with but separately from the winding action, unlike ring spinning where twisting and winding actions occur together.
Advantages of Open end spinning System:
· lower power consumption per unit quantity of yarn produced
· higher speed of twist insertion resulting in very high yarn delivery speed
· a significant resulting increase in productivity
· larger delivered package size
· elimination of some processes such as roving and winding
· more uniform yarns
