Manufacture of Hollow Cross Sectional Regenerated Cellulose Fiber Using HWM Spinning Method

Traditional regenerated cellulose fiber (viscose or viscose fiber) had a poor wet breaking strength and wet modulus, which to some extent limited the application of the fiber. Hollow viscose was difficult to get for its instability during the cellulose regenerating process. This paper introduced one kind of new spinning method for hollow viscose through a spinneret of concentric shaft structure using HWM technology. The hollow viscose fiber produced in this experiment had a big crystalline structure and an excellent fibril orientation which gifted the fiber a good mechanical performance even under wet circumstances. The fiber had a bright future in textile application as one component of blending fabrics.
