Design of a navel and its influence on yarn structure.

The texture of a yarn describes the orientation of individual fibers in a yarn group. This yarn structure is determined by the application. The OE-rotor spinning system is a very flexible solution among staple fiber spinning processes, since it allows yarn manipulation through the use of various spinning elements. For example, the design of the navel has a significant influence on the yarn structure. The opening roller and rotor are responsible for a large proportion of: the measured number of imperfections, the yarn uniformity, and damage to the fibers. The principal item however, the navel, is able to broadly manipulate yarn volume and hairiness, without necessarily having a negative effect on processing parameters, such as tenacity and elongation. The character of a textile product can be predominantly controlled by the navel.
