preparation example Construction

[0039] The present invention also provides a preparation method of the nanofiber covered yarn described in the above technical solution, comprising the following steps:

[0040] placing the cotton yarn in the aqueous dispersion of pyrrole monomer to obtain a solution of pyrrole soaked in the cotton yarn;

[0041] FeCl 3 - adding p-toluenesulfonic acid solution dropwise to the pyrrole solution soaked in cotton yarn, and performing in-situ oxidation polymerization to obtain polypyrrole-cotton yarn;

[0042] The polyacrylonitrile-ketoconazole solution is used as the positive electrode electrospinning solution, the polyacrylonitrile-nano zinc oxide solution is used as the negative electrode electrospinning solution, and the polypyrrole-cotton yarn is rotated and coated by double-electrode electrospinning , to obtain nanofiber-coated yarn.

[0043] In the invention, the cotton yarn is placed in the aqueous dispersion liquid of the pyrrole monomer to obtain the pyrrole solution so...

Embodiment 1

[0061] Step (1): Weigh 30g of cotton yarn, soak it in absolute ethanol for 30min, rinse it with deionized water, and let it dry naturally.

[0062] Step (2): According to the bath ratio of cotton yarn and deionized water as 1:60, measure 1800mL of deionized water, add 54.27g of pyrrole monomer dropwise, stir until it is evenly dispersed in deionized water, and then put the cotton yarn into the above-mentioned pyrrole monomer aqueous dispersion, stirred for 5 minutes and soaked for 30 minutes to obtain the pyrrole solution soaked in cotton yarn.

[0063] Step (3): According to the amount of pyrrole, according to FeCl 3 The mass ratio of pyrrole to 3:2 weighs FeCl 3 , calculate and weigh 171.198g of p-toluenesulfonic acid, FeCl 3 and p-toluenesulfonic acid were poured into 1800mL deionized water, and magnetically stirred for 30min until completely dissolved to obtain FeCl 3 - p-toluenesulfonic acid solution.

[0064] Step (4): Place the pyrrole solution soaked in cotton yarn...

Abstract

The invention provides a nanofiber wrap yarn, a preparation method of the nanofiber wrap yarn, a nanofiber wrap yarn plied yarn and application of the nanofiber wrap yarn plied yarn, and relates to the technical field of antibacterial textiles. The nanofiber wrap yarn provided by the invention comprises a core yarn and an outer wrapping layer wrapping the surface of the core yarn, the core yarn is polypyrrole-cotton yarn; the polypyrrole-cotton yarn comprises cotton yarn and polypyrrole particles distributed on the surface of the cotton yarn; the outer cladding layer is made of antibacterial nanofibers; the antibacterial nanofiber comprises a polyacrylonitrile nanofiber matrix as well as ketoconazole and nano zinc oxide which are distributed on the polyacrylonitrile nanofiber matrix. The nanofiber wrap yarn provided by the invention has a relatively good inhibition effect on fungi and bacteria, particularly has a certain treatment effect on tinea pedis, is relatively low in cost, safe and reliable, and has durability and slow release property.

Description

technical field [0001] The invention relates to the technical field of antibacterial textiles, in particular to a nanofiber-coated yarn and a preparation method thereof, a nanofiber-coated yarn strand and an application thereof. Background technique [0002] In daily life, people inevitably come into contact with various pathogenic microorganisms, which multiply and grow rapidly in a suitable environment. Due to its porous and loose structure, textiles are easy to absorb various impurities and become one of the main carriers of breeding and parasitic bacteria. When textiles are in contact with the human body, microorganisms will grow and multiply on the surface of the body, and once they reproduce too much, they will cause skin diseases. Wherein tinea pedis is caused by fungal infection, and the incidence rate is high (the crowd incidence rate can reach 15-20%). In the later stage, along with the development of the disease or scratching, bacterial infection can be caused, a...
