Next week is the May Day holiday
Are you ready to go out and surf 😆?
Travel, though
There's one thing that's big
That's the underwear that you have to change every day
I washed it on the day
It's troublesome and I'm afraid it won't do it
Save it up and take it home, it's not very hygienic
Smart and lazy people will buy disposable panties
It's convenient to throw it away when it's gone
But vegetarian
Are disposable panties really safe
What kind of disposable panties are good?
🧐🧐🧐
01
Look at the fabric: pure cotton is not necessarily good!
·
Nonwovens, NO!
Cheap disposable underwear is usually made of "non-woven" material, and the biggest advantage is that it is cheap.
Its production process is similar to that of a face towel, but if you pull it slightly, it is easy to lose shape or even break holes, and if you rub it a few times, there will be visible flocculents.
Moreover, this material is not breathable and sweat-absorbent, and it will feel stuffy and unbreathable after wearing it for an hour or two, so don't choose it!
Non-woven materials on e-commerce, choose carefully!
·
Pure cotton, it depends!
Everyone's subconscious must think that cotton is the best material, but for disposable underwear, not necessarily!
Some netizens said that after wearing substandard disposable underwear, it caused gynecological diseases, because they bought disposable underwear processed from "recycled cotton".

There are many disposable underwear on the market made of pure cotton, but the medium and low count combed cotton fabric is the main one, and the quality of this fabric is inferior, so it's best not to choose!
·
Regenerated cellulose/viscose
The material that is more suitable for making disposable underwear is regenerated cellulose fiber/viscose fiber. This material dissolves trees and cottonseed lint and then spins it, and the moisture absorption can be 50% higher than that of cotton itself, and it is not easy to lose hair!
Its only drawback is that it is easy to wash and shrink. However, since it is disposable, we don't have to think about washing!
02
Look at the sterilization process:
Look for high-energy electron beam sterilization
·
EO sterilization
Most disposable underwear is sterilized with ethylene oxide (EO). Ethylene oxide is a broad-spectrum sterilant that kills a variety of microorganisms at room temperature.
The disadvantage is that it has a peculiar smell, and if the smell is not complete, it is easy to have residues.
·
High-energy electron beam sterilization
This sterilization method uses radiation to kill microorganisms that remain in the product. It has the advantage of thorough sterilization, safe operation and no residue.
It is widely used in food sterilization, such as the "dehydrated vegetables" in the instant noodles we eat, because there is no additional chemical sterilization agent introduced, so there is no odor residue.
03
These standards must be there!
When we buy disposable underwear, we should also pay attention to whether the packaging is marked with "hygiene standards" and "safety technology categories", many three-no products are not, and some products may only be marked with one.
👉 Hygienic standards
Look for the GB15979-2002 "Hygiene Standard for Disposable Sanitary Products", which means that the disinfection is up to standard.
👉 Safety Technology Category
Look for the GB18401-2010 "National Basic Safety Technical Specifications for Textile Products", and products in direct contact with the skin should at least meet the requirements of Class B.
👉 Product standards
The product standard can be seen that the production of disposable underwear is not qualified, such as the situation that it is not easy to break and take off the thread.
Look for the standard of GB/T8878-2023 "Knitted Underwear", which is produced before December 1, 2023, and the standard of GB/T8878-2014 is also acceptable.
