High-tech underwear for body wear! Is graphene underwear a waste of money?

"Dehumidification and sterilization", "long-lasting dryness", "anti-inflammatory invasion"... In recent years, many underwear merchants have launched the concept of graphene, claiming that it has many effects. Is it really so?

Is graphene underwear a waste of money? First of all, we need to understand what kind of material graphene is.

Graphene is a new material with a two-dimensional structure of a single layer of carbon atoms. It is the lightest and strongest material known so far, with characteristics such as large specific surface area, strong electrical and thermal conductivity, and good antibacterial properties. Graphene is very thin, only one layer of atoms thick, and its production process is very complicated, so the production cost is extremely high, and it is difficult to obtain in large quantities.

At present, graphene mainly exists in textiles in the form of coatings and graphene-modified fibers. Whether graphene underwear can achieve the advertised effect depends mainly on the following factors:

Whether underwear products contain real graphene materials.

If a product uses real graphene material, its content determines the product's efficacy. The greater the amount of graphene used, the more obvious the functional effect, and of course the higher the price.

If underwear products do not contain real graphene materials or the graphene content is low, such products are just hype concepts, and the advertised effects are difficult to achieve. At present, the detection methods for graphene materials are still imperfect and the detection level is limited. Therefore, when consumers cannot experience the expected effects, it is often difficult to protect their rights.

Things to note when choosing underwear:

1. Comfort. Underwear is described as the second layer of skin of the human body, so comfort is the first factor in choosing underwear. Comfort mainly refers to touch, breathability, moisture permeability, etc. In addition to being related to the raw materials used in the underwear, it is also related to the pattern. The pattern design must conform to the principles of ergonomics. Generally, the fabric composition of the underwear and the implementation standards of the product can be checked through the hangtag, and the pattern needs to be experienced through trying on.

2. Functionality. Some products are advertised as having properties such as antibacterial, anti-ultraviolet, improving microcirculation, and promoting metabolism. Consumers should make rational choices based on their needs, because the functionality of underwear often means a high price. Consumers should judge whether it is worth buying the product at a high price.

3. Fashionable appearance. In modern society, underwear is no longer just underwear, but also an important part of fashion. People choose their favorite styles according to their mood and occasion to show their style and personality. For daily underwear, try to choose light colors.
