Abstract

The invention provides a preparation method of a polyester filament yarn containing a mint extract. The preparation method is characterized in that the content of the mint extract is 0.1-5%. The specific preparation method comprises the steps of preparation of SiO2 porous gel powder, preparation of modified particles containing mint extract, preparation of polyester functional powder, melt spinning, annular cooling, oiling and drafting treatment, heat setting and winding. The filament number of the polyester filament yarn prepared through the process is 0.3-0.5 dpf, the breaking strength reaches 7.5-7.8 cN/dtex, and the elongation at break is 32-36%; and meanwhile, the polyester filament yarn also has the characteristic of natural bacteriostasis of plants, the antibacterial rate on staphylococcus aureus, escherichia coli, candida albicans and other bacteria easily infected by a human body reaches 96.0-98.5%, and after 50 times of standard washing, the antibacterial rate is still 90-91%, and the antibacterial durability is good.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a polyester filament containing mint extract and a preparation method thereof. Background technique [0002] Polyester is the trade name of polyester fiber in my country, and it is an important variety of synthetic fibers. Polyester fiber is called a new generation of synthetic fiber, which has the characteristics of warmth, lightness, breathability, close-fitting, comfort and softness. It has achieved results that are difficult to achieve with other fibers, especially polyester imitation silk knitted fabrics. It not only has the advantages of moisture absorption and breathability of silk, and is comfortable to wear, but also overcomes the shortcomings of silk fabrics such as easy to wrinkle, stick to the body and poor fastness, especially in knitted fabrics. In the organizational structure, the fabric is endowed with good extensibility, drapability and air permeabilit...
