Problems solved by technology

[0003] Most of the medical protective clothing fabrics in my country are made of multiple materials, such as compact textiles, coatings, and composite microporous membrane technology. The protective clothing fabrics made by these methods all have a common problem, that is, the garments are poor in comfort and breathability. And poor thermal insulation performance, long-term wearing will bring physical discomfort to medical staff

Abstract

The invention provides a nanofiber medical thermal insulation protective clothing fabric and a preparation method thereof. The preparation method comprises the steps of taking non-woven fabric textile fibers as base cloth, and performing single-face magnetron sputtering of a nanoparticle coating, so that a treated non-woven fabric is obtained; dissolving and dispersing a polymer and zinc oxide nanoparticles in a spinning solvent to obtain a polymer spinning solution; and carrying out coaxial electrostatic spinning to obtain a polymer particle composite nano film as a middle layer, taking the treated non-woven fabric as a surface layer and a bottom layer, and carrying out ultrasonic bonding to obtain the medical thermal insulation protective clothing fabric which integrates the functions of electrostatic spinning ventilation, hollow fiber thermal insulation, anionic antibiosis, static electricity resistance and the like, and has comfort and protective safety. The nanofiber with the diameter of dozens or hundreds of nanometers can be obtained by utilizing the electrospinning technique, has the dual advantages of a nano material and a fiber material, has the characteristics of light weight, excellent air storage due to a hollow structure and the like, and is particularly suitable for being used as a thermal insulation material.

Description

technical field [0001] The invention belongs to the technical field of medical protection, and in particular relates to a nanofiber medical thermal insulation protective clothing fabric and a preparation method thereof. Background technique [0002] With the development of the new crown epidemic, the outbreak of the epidemic has greatly increased the use and demand of medical products. In order to avoid cross-infection, medical protective materials are disposable materials. Medical protective clothing should be able to effectively prevent the blocking effect of liquids, microorganisms and particles, which is an important guarantee for protecting medical staff. Many institutions and researchers are committed to improving the protective properties of fabrics, while ignoring the wearing comfort, breathability and warmth of protective clothing in winter. [0003] Most of the medical protective clothing fabrics in my country are made of multiple materials, such as compact texti...
