Latest Patents

Jigang Xu's latest patents reflect his commitment to improving the efficiency and quality of cellulose fiber production.

1. **Continuous Preparation Method of Cellulose Fibers**: This patent discloses a continuous method where a forming tension of 0.1 to 1.9 cN/dtex is applied to a fine solution stream. This stream, acquired through extrusion, undergoes air gap cooling before entering a coagulating bath at a speed of 80 to 1000 m/min. A traction tension of 0.075 to 1.5 cN/dtex is maintained in the subsequent washing system, leading to the effective spinning of finished fibers at specific speeds.

2. **Method for Preparing Cellulose Fiber**: The disclosed method involves mixing cellulose pulp with an NMMO aqueous solution to yield a homogeneous mixture. This mixture is processed through a series of steps involving dewatering, filtering, and air cooling, ultimately producing nascent fibers which are subsequently rinsed and treated to form high-quality cellulose fiber.
