Problems solved by technology

[0003] In the prior art, Paraguay Pombello Clothing Company once released a mosquito repellent shirt to the market, which was soaked with citronella essential oil. Mosquitoes hate the taste of citronella essential oil, so it has mosquito repellent effect; In the process of fiber and use, there is a lot of loss of active ingredients; in addition, the mosquito repellent insecticide permethrin formula is added to the fiber to prepare mosquito repellent fiber, but the insecticide is a chemical component, which is harmful to health and cannot meet the needs of current consumption. To meet the needs of consumers for healthy, green, and natural products, choose natural, herbal, and green mosquito repellent ingredients, and the market prospect is broad
[0004] CN109487360A provides a kind of polyester fiber containing plant extracts, which adds various compound plant extracts such as coral extract, mugwort extract, snow lotus extract, seaweed extract, hexacyclic stone powder and halloysite powder when preparing polyester fiber Although many auxiliary components such as surface active phospholipids can effectively improve the antibacterial properties of polyester fibers, the preparation process is relatively complicated. Plant extracts and auxiliary materials need to be prepared separately and react in multiple stages. The reaction rate is not high. The final prepared Polyester fiber containing plant extracts, plant extracts are easy to lose ingredients
[0005] CN201910546151.X discloses a method for preparing polyester fabrics. The polyester filaments are bleached, soaked, etc., so that citronella oil, chrysanthemum, wormwood leaves, and cocklebur are added to the polyester fabric as mosquito repellent ingredients, so that the polyester fabric has Mosquito repellent, and prolong the use time of mosquito repellent, but it impregnates the fabric with plant extracts by soaking, and the organic components still volatilize quickly when exposed to high temperature conditions such as hot water and ironing, and the preparation process is complicated. High equipment occupancy rate and high production cost
