Everyone is familiar with digital watches, which have sold a lot due to the fact that they are resistant to acceleration and mechanical shock, because their performance has become a brand name.
Is that digital watch really shock-resistant?
Someone wanted to buy the watch and see if it was really shock-resistant, and when he hit it on the ground, it seemed to break. He was shocked.
Well, since it has fewer parts and fewer assembly processes than a wristwatch with mechanically moving hands, it is not a mistake to think that it has excellent mechanical strength.
Nonetheless, there are some caveats with that digital watch. It is the aging of the surface of the body and belt.
Why was the mixed fiber devised?
After several years
the polyurethane covering the surface is denatured and cracks or breaks.
Chemically synthesized materials such as polyurethane, plastic, nylon, vinyl and rubber are excellent materials that are colorful, lightweight and inexpensive for a while, but they are not suitable for long-term use.
In addition, when used in clothing, chemically synthesized artificial fibers have generally been avoided from the viewpoint of touch.
In particular, artificial fibers are basically difficult to use for underwear that comes into direct contact with the skin. After all, we want to wear cotton underwear.
Cotton products are comfortable to wear and have excellent water retention.
Cotton is hard to dry
However, since cotton is a material derived from natural products rather than artificial products, it is reminiscent of certain environmental destruction. In addition, the fact that cotton products are manufactured and processed mostly in developing countries involves social issues.
But those miscellaneous stories about cotton are to some extent dramatized by the mass media, so you don’t have to worry seriously.
So is cotton the king of textiles?
We know that the honor student of textile materials also has drawbacks. Cotton is hard to dry, and cotton is easy to wrinkle.
That’s the goodness of cotton!
If you assert so, you should reject all artificially synthesized items and become a self-sufficient hippie. Love & Peace!
In reality, a method was adopted to add a function to overcome the shortcomings of natural products. Artificial fiber was mixed with cotton at a ratio of some percentage. These mixed fibers are soft to the touch, dry easily, and are less likely to wrinkle.
What is the material of your mask? please make sure. You should love masks. Because we are likely to continue to use it for a long time.
