Abstract

The invention provides a nano-antibacterial fiber compounded underpants fabric and a preparation method thereof. The preparation method comprises the specific steps of: adding a molecular sieve into asilver nitrate solution, performing standing adsorption after even mixing, and obtaining a nano-silver loaded molecular sieve after filtering, drying and roasting are conducted; dispersing the nano-silver loaded molecular sieve in a high-molecular polymer solution, and performing defoaming to obtain a nano antibacterial spinning solution; adding the nano-antibacterial spinning solution into a liquid storage mechanism of electrostatic spinning equipment, taking the base cloth layer as a spinning collection mechanism for electrostatic spinning, and directly electrospinning a composite nano-antibacterial fiber layer on the surface of the base cloth layer by using the electrostatic spinning equipment; compounding the fabric layer on the outer surface of the nano-antibacterial fiber layer by adopting a hot pressing process to obtain the underpants fabric compounded with the nano-antibacterial fibers. Silver and graphene are processed into nanofibers and quickly embedded into the fabric, multiple antibacterial materials are compounded into the nano antibacterial fibers at a time, and the nano antibacterial fibers have high porosity and high specific surface area and bring air and moisture permeability and antibacterial effects.

Description

technical field [0001] The invention relates to the technical field of garment processing, in particular to the field of polymer materials, and relates to a composite nano antibacterial fiber underwear fabric and a preparation method thereof. Background technique [0002] Underpants, as people's personal clothing, have higher and higher requirements from consumers for their comfort, breathability and moisture permeability, and the ability to keep clean. Traditional fabrics do not perform well in maintaining long-term antibacterial effects, and it is difficult to prevent bacteria from growing, producing odors, and affecting health. Most of the antibacterial fabrics on the market add synthetic antibacterial agents and antibacterial nano-silver to enhance the antibacterial properties of the fabrics, but synthetic antibacterial agents have the problem of irritating the skin, and are easy to fall off and remain, while antibacterial nano-silver can be absorbed into the skin throug...
