I clicked in when I saw this title
I must have a deep understanding of this matter
The underwear is worn for a little longer
The crotch will become hard
If it's a different location
It probably doesn't matter yet
But the crotch hardens here
The comfort of wearing is directly reduced
So
Let's look at it today
This position in the crotch of the panties
Why does it always get hard?
1- It has to do with the material of the underwear
As we all know
The rest of the panties are basically a layer of cloth
Only the crotch is here, and there are two layers
There is an extra piece of cotton fabric on the inside
Some of the panties are called "cotton".
If you look closely at the fabric table, you can find out
In fact, there is only this piece of cloth on the crotch
It is a real "100% cotton"
The original intention of designing this cloth
Originally, it was also for the comfort of wearing
If you keep enlarging this cloth
You can see that the fibers are all distributed in strips
At the same time, there are many gaps
The starting point is good
But after wearing it for a while, after washing it many times
It's a little different
Pure cotton fibers
There are more hydrophilic groups
It will absorb water from the outside
After each wash
Even if it is fully dried
There will still be some in pure cotton fibers
Residual water
The water left behind by these is not willing to be lonely
will put the original strip-like fiber
Linked into a mesh
As a result, the fibers cannot slide between each other
in time
The crotch will harden first
Something similar
On items such as socks, towels, etc
It also happens
2- It is related to the secretions of the body
In terms of secretions
Boys are a little better
There will usually only be one on the underwear
Here are four substances –
And the girls are on their side
The situation is very complicated
First of all
It's a combination of several substances
Secretions from the genital tract
That is, the daily "white belt"
secondly
When ovulation is approaching
May secrete "Pasteur's gland fluid"
At last
Don't forget that there is also a menstrual period
Almost every girl has encountered it
If you accidentally get a blood stain
These substances are mixed together
Remains in the crotch of the underwear
It is usually rubbed and squeezed
It is easy to infiltrate into
go between the holes between the fibers
These substances mentioned above
Basically all contain protein
After oxidation, it will denature and solidify
Firmly attached to the fibers
Usually the underwear is not cleaned properly
These substances slowly build up together
The crotch of the panties will become harder and harder
In addition to the problem of hardening
These secretions accumulate in the crotch
It can also harbor bacteria
This, in turn, endangers the health of the intimate area
3- It is related to the way of cleaning and drying
Because there is a lot of secretion, it is easy to get dirty
A lot of people when washing their underwear
There will be the following two operations -
Pour a lot of laundry detergent over the crotch
Use soap to wash stubborn stains on the crotch
These two habits
will make the crotch harden even more serious
Add too much laundry detergent
It may remain in the crotch here
Make it harden faster
And the main ingredient of soap
It is a sodium salt of fatty acids
It binds to calcium, magnesium, etc. in tap water
Calcium soap that is insoluble in water is formed
Calcium soap
It is also easy to deposit on the fibers
Causing the panties to stiffen and stiffen
Underwear is a small piece of clothing
Generally, it is not dried separately
It's usually a hanger after washing
Dry it directly
A lot of people when they are drying
This is usually done in the following way
Under the influence of gravity
Water on the panties will collect up to the crotch
Calcium and magnesium ions in tap water
It also aggregates here in the crotch
And then it gets harder and harder
That's it
The crotch of the panties is easy to harden
There are several main reasons
Want to avoid this problem
Actually, it's not that hard
The previously mentioned methods of washing and drying
Everyone should try to avoid it
Also, change your underwear regularly
Treat underwear as consumables, don't be reluctant~
