Title: **Innovations of Kedong Chi: Pioneering Cellulose Fiber Technology**

Introduction

Kedong Chi is a notable inventor based in Beijing, China, recognized for his significant contributions to the field of cellulose fiber technology. With an impressive portfolio of two patents, Kedong has developed innovative processes that enhance the production and quality of cellulose fibers, making strides in the textile industry.

Latest Patents

Kedong Chi's latest patents reflect his commitment to advancing cellulose fiber production. The first patent, titled "Continuous Preparation Method of Cellulose Fibers," details a method involving a forming tension of 0.1 to 1.9 cN/dtex applied to a fine solution stream. This stream, extruded through a spinneret plate and subjected to air gap cooling, is then fed into a coagulating bath at speeds ranging from 80 to 1000 m/min. This innovative process applies a traction tension of 0.075 to 1.5 cN/dtex to the washed fibers, enabling a continuous and efficient spinning of the finished fibers.

The second patent, "Process for Preparing Cellulose Solution and Equipment Therefor," provides a comprehensive methodology for creating a cellulose solution. It involves the continuous mixing of NMMO with low concentration and non-activated pulp, followed by evaporation dewatering until the optimal NMMO concentration is achieved. This method addresses the challenges of uniform mixing and sufficient swelling, while also mitigating safety issues related to high concentration NMMO in traditional methods.
