Detailed Description
For the purpose of more clearly illustrating the present invention and more clearly understanding the technical features, objects and advantages of the present invention, the technical solutions of the present invention will now be described in detail below, but are not to be construed as limiting the implementable scope of the present invention.
The polyester fiber has higher strength and elastic recovery capability, so the polyester fiber is firm and durable, and is crease-resistant and non-ironing. However, it has poor moisture absorption and breathability, and is stuffy to wear, which limits its application.
The moisture-conducting polyester fiber prepared by the invention achieves the effect of unidirectional moisture conduction by introducing hydrophilic swainsonine and water-repellent and oil-repellent trimethoprim on the surface of the polyester fiber. The invention grafts the swainsonine on the surface and in the pore diameter of the polyester fiber to increase the hygroscopicity and the moisture permeability of the polyester fiber, then fixes and graft-modifies the swainsonine by using the trimethoprim, the trimethoprim has better antibacterial performance, and the surface of the trimethoprim has a large amount of hydrophobic and oleophobic groups, therefore, the combination of the trimethoprim and the swainsonine can absorb sweat generated by a human body through the moisture-absorbing polar groups on the surface of the moisture-permeable polyester fiber or in the fiber, and the existence of the hydrophobic groups can ensure that the fiber does not expand like the moisture absorption of cotton fiber, and the absorbed sweat or sweat can be transferred to the outer layer along the fiber-guiding or micropore transfer axis, thereby rapidly diffusing and transferring the water vapor and the moisture, and rapidly drying the fabric.
