Description

Coagulation and shaping device for cellulose spinning

technical field

The invention relates to the technical field of textile machinery, in particular to a coagulation forming device for cellulose spinning.

Background technique

Cellulose fibers are known to be environmentally friendly, have a short production process, and have excellent properties, especially for applications such as fabrics, and in high-strength forms, also for technical applications such as tire cords. Cellulose fibers are prepared by a dry spray-wet method. During the spinning process, the cellulose tow passes through the air gap, and the molecular chains in the liquid crystal region are stretched and oriented under the action of shearing force, and then enter the coagulation bath to solidify and form. Therefore, when passing through the air gap, the stable high-speed stretching orientation of the cellulose tow is achieved, which determines the strength and quality of the cellulose fiber.

In the prior art, in the production process of cellulose spinning, a spinning acceleration funnel is often used to achieve high-speed drawing of the tow.
