Problems solved by technology

In the process of adding tourmaline powder to prepare negative ion polyester fiber, if the tourmaline powder is not modified in any way, it will cause significant aggregation of tourmaline powder, which will eventually cause problems such as difficulty in spinning and forming, uneven distribution of tourmaline powder in the fiber, poor mixing effect, etc.

Abstract

The invention relates to the technical field of polyester fiber production, and concretely relates to an antibacterial composite functional fiber and a preparation method thereof. The preparation method comprises the following steps: modifying tourmaline powder with glycidyl methacrylate, coupling the modified tourmaline powder with a far-infrared ceramic powder to prepare a composite powder, andadding the composite powder in a polycondensation reaction of polyester fibers to prepare the composite fiber. The antibacterial composite functional fiber is prepared by the method, and has the composite functions of resisting bacteria, releasing negative ions and emitting far infrared rays. The tourmaline powder is modified to effectively reduce the coagulation effect of the tourmaline powder inthe fiber preparation process, increase the dispersion stability of the tourmaline powder and solve the problem of difficult spinning formation and the problems of uneven distribution and poor mixingeffect of the tourmaline powder in the fiber.

Description

technical field [0001] The invention relates to the technical field of polyester fiber production, and more specifically relates to an antibacterial composite functional fiber and a preparation method thereof. Background technique [0002] Negative air ions are a substance that is very beneficial to human health. The human body inhales a certain concentration of negative ion air, which can regulate the function of the nervous system, promote blood circulation, and make people energetic. [0003] Tourmaline, also called tourmaline, is a natural mineral containing a variety of elements. The main components are magnesium, aluminum, iron, boron and more than 10 kinds of trace elements that are beneficial to the human body. Because it is a polar crystal with a special structure, it can generate electric ions for a long time and release negative air ions and far-infrared rays permanently. Therefore, it has been widely used in the functional modification of fiber materials, so tha...
