Abstract
The invention discloses an antibacterial multifunctional polyester fiber based on wormwood and a preparation method of the antibacterial multifunctional polyester fiber, particularly relates to the technical field of fiber materials, and relates to the antibacterial multifunctional polyester fiber based on wormwood and the preparation method of the antibacterial multifunctional polyester fiber. The antibacterial multifunctional polyester fiber based on wormwood is prepared from terephthalic acid, ethylene glycol and wormwood extract. The preparation method specifically comprises the following steps: synthesizing polyester by taking terephthalic acid and ethylene glycol as raw materials, adding a wormwood extract during synthesis to obtain a polyester melt, and then spinning the polyester melt in a screw extruder to obtain nascent fibers; stretching, curling and shaping the nascent fiber to obtain the wormwood antibacterial multifunctional polyester fiber. The wormwood component with certain hygroscopicity is added, the hygroscopicity is improved, moisture can be absorbed, a water film is formed on the surface of the fiber, the flexibility of the fiber can be improved, heat exchange and moisture transfer between air and the fiber can be promoted, and the hygroscopicity is improved.
