Description
Technical Field
The invention belongs to the technical field of medical protection, and particularly relates to a nanofiber medical heat-preservation protective clothing fabric and a preparation method thereof.
Background
With the development of new coronary epidemic situation, the use amount and the demand of medical products are greatly increased due to the outbreak of the new coronary epidemic situation. The medical protective material is a disposable material product for avoiding the generation of cross infection. The medical protective clothing can effectively prevent the blocking effect of liquid, microorganisms and particles, and is an important guarantee for nursing medical care personnel. Many organizations and researchers have been working on improving the protective properties of fabrics, while neglecting the wearing comfort, breathability and warmth of protective garments during the winter period.
The fabrics of the medical protective clothing in China are mostly compounded by a plurality of materials, such as compact textiles, coatings and composite microporous films, and the fabrics of the protective clothing prepared by the methods have a common problem, namely, the fabrics have poor comfort, poor air permeability and poor heat preservation performance, and can bring physical discomfort to medical care personnel when being worn for a long time. The electrostatic spinning technology is a method for forming jet flow by using high-voltage electrostatic action on polymer solution or melt and further stretching and solidifying the jet flow in an electric field so as to obtain continuous micro-nano fibers, and the electrostatic spinning is one of main ways for preparing nano fiber materials.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a preparation method of a nanofiber medical heat-preservation protective clothing fabric. The principle is that a spunbonded fabric textile fiber material is used as a base fabric, an electrostatic spinning technology is utilized, a long-acting electret technology is combined, a polymer spinning solution is sprayed on a non-woven fabric coated with nano ions in a nano fiber form through high-voltage static electricity, and the non-woven fabric is compounded through an ultrasonic bonding technology.
The invention also aims to provide the nanofiber medical heat-insulation protective clothing fabric which has excellent comfort and heat insulation and has important practical significance for current epidemic situation protection and daily life health.
In order to achieve one of the above purposes, the solution of the invention is as follows:
a preparation method of a nanofiber medical heat-preservation protective clothing fabric comprises the following steps:
(1) carrying out single-side magnetron sputtering of the nano particle protective coating on the non-woven fabric to obtain a treated non-woven fabric;
(2) dissolving the polymer and the zinc oxide nanoparticles, and dispersing the polymer and the zinc oxide nanoparticles in a spinning solvent to obtain a polymer spinning solution;
(3) the treated non-woven fabric is used as a base fabric, and the polymer spinning solution is coaxially and electrostatically spun on the base fabric to obtain a polymer particle composite nano-film, namely a layer of hollow nano-zinc oxide composite film is spun on the non-woven fabric which is magnetically sputtered with nano-particles by utilizing coaxial electrostatic spinning;
(4) and respectively using the treated non-woven fabric as a surface layer and a bottom layer, using the polymer particle composite nano film as a middle layer, and obtaining the nano fiber medical heat-preservation protective clothing fabric through an ultrasonic bonding process.
