On the bobbin 7.
- Ramie is difficult to weave high-yarn yarn due to coarse fiber, high rigidity and poor cohesion.
- Sirofel spinning can spin more than 80 high-count yarns, the yarn structure is a common core structure.
- the ramie fiber is easy to fall off, which affects the subsequent processing and use effect.
- the formed yarn is equivalent to two Sirofil spinning yarns and is twisted and twisted.

- the two rovings, a, fed together can be combined to feed a roving.
- Ultra-high count yarn generally refers to more than 120-inch cotton yarn and 220-gram wool yarn. Due to the high yarn count, the number of fibers in the yarn cross section is small (close to the limit number), so it is difficult to directly spin, generally using soluble fiber The method of spinning and dissolving the soluble fiber is processed, and the method for spinning the ultra-high count yarn is mainly used for the filament sirofel. Since the number of fibers in the cross section of the spun yarn is too small, the problem of poor coating with Sirofil spinning is easy, the spinning is easy to break, and the surface of the fabric after the spinning of the spun filament is dissolved, the influence is inevitable.
- the filament fiber plays a certain supporting role on the fiber strands output from the front jaw, and can also effectively prevent yarn breakage during the spinning process and improve the spinning efficiency.
