A novel approach to improving the quality of chitosan blended yarns using static theory

摘要

Chitosan is a desirable material for several reasons, including its biocompatibility, biodegradability, non-toxicity, and excellent absorption. Rapid progress in material science has resulted in the development and widespread use of chitosan in the textile industry primarily because it is polycationic and can inhibit microorganism activity. However, high electrostatic, poor mechanical properties, and the polycationic property of chitosan materials, which are the main reason for the electro-static generation of chitosan fibers, have a negative impact on the spinning process and lower the quality of chitosan yarns. Therefore, there is a critical need to reduce production losses and improve the poor spinnability. A new spinning approach exploits triboelectric electrostatic theory to efficiently remove the electric charge and to promote yarn formation under optimum conditions precisely and controllably, thereby minimizing waste and achieving a high utilization ratio of the chitosan fibers. Lagrange interpolation is used to systematically analyze the basic mechanical properties of the developed materials. The results show that the tenacity of chitosan/PAN blended yarns is superior to that of chitosan/cotton blended yarns because of the complementary effect of positive and negative charges; and the novel application of static theory can be used to effectively resolve the high static and reduce material cost problems in the yarn production process. This new approach is expected to promote the usage of chitosan fibers in the textile industry and in medical applications.
