Problems solved by technology

The high degree of polymerization, high strength, high crystallinity, and high hydrophilicity of nanofibers have attracted more and more attention from science and technology and industry, and the research on preparing nanofiber composites has also attracted much attention. Composite thermal fabrics have a certain pioneering value, and thermal insulation materials made of nanofibers have not yet appeared in the prior art

preparation example Construction

[0043] The present invention also provides a preparation method of the above-mentioned composite thermal fabric, the method comprising the following steps:

[0044] (1) Take graphene oxide and disperse it in deionized water; place the graphene oxide in deionized water, carry out ultrasonic dispersion for 40-50 minutes, the operating frequency during ultrasonic dispersion is 20-50kHZ, and the dispersion is completed to obtain graphene oxide dispersion liquid;

[0045] Preferably, the operating frequency during ultrasonic dispersion is 30-40kHZ.

[0046] (2) according to the required mass ratio, polyvinyl alcohol is dissolved in the graphene oxide dispersion of step (1) to swell, and the mass fraction of polyvinyl alcohol added is 5wt%~10wt% (and meets the requirements of polyvinyl alcohol and The mass ratio of graphene oxide is 7:0.1~7:0.5.), swelling after adding for 45~55min;

[0047]Then heat at 90-100° C. for 3-5 hours, and cool to room temperature after heating to obtain...

Abstract

The invention discloses a composite thermal fabric and a preparation method thereof. The preparation method comprises the steps that firstly, a polyvinyl alcohol / graphene solution is prepared from polyvinyl alcohol and graphene, then the polyvinyl alcohol / graphene solution and polyethylene glycol are prepared into a polyvinyl alcohol / polyethylene glycol / graphene mixed solution, and the polyvinyl alcohol / polyethylene glycol / graphene mixed solution is electrospun on a spun viscose fabric layer to obtain the nanofiber composite thermal fabric. The fabric can serve as outerwear for warm keeping and can also automatically generate body heat, and growth of bacteria is avoided while the body heat is generated. The fabric has a good thermal effect. The fabric is simple and convenient to prepare, light, good in thermal effect, high in practicability, good in application prospect and remarkable in social and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of nanofiber preparation, and specifically relates to a composite thermal insulation fabric and a preparation method thereof, in particular to a nanocomposite fiber composite thermal insulation fabric and a preparation method thereof. Background technique [0002] The role of thermal insulation materials in people's lives cannot be ignored. With the development of the economy, thermal insulation materials currently on the market mainly refer to materials whose raw materials are often formed in the form of flakes or flocs, which have thermal insulation effects, but are bulky and heavy. And the warming effect is average, especially in areas with severe cold temperatures, it is extremely inconvenient to wear clothes with a large volume and a large amount of materials. [0003] Nanofiber refers to a thread-like material with a diameter of nanometer scale. Nanofiber can also be made into porous and film-forming f...
