How warm is thermal underwear?
Thermal underwear, accompanied by the image advertisements of big-name stars, has formed a kind of
Beautiful scenery fully demonstrates the charm of functional high-tech textiles. So, keep warm.
What is the thermal performance of underwear? Far infrared fiber, Antarctic cotton, lycra, what is it?
What is it? These questions are what consumers want to know.
Principles of thermal underwear
The material structure of thermal underwear consists of inner and outer fabrics and a middle composite layer. middle
Composite layer is the key to thermal underwear. Initially, the composite layer of thermal underwear was made of agricultural film.
Technically, the use of plastic film has excellent heat insulation and wind resistance, forming an effect that is difficult to form in general textile materials.
So as to achieve the effect of keeping warm. Punch a certain number of small holes in the film by acupuncture technology.
Composite some fibers (so-called Antarctic cotton) on both sides of the film, and then use this composite layer.
Adhesive binds the inner and outer knitted fabrics together to form the material of thermal underwear.
Now the material of thermal underwear has been generally changed to special chemical fiber, mainly superfine.
Fiber, hollow fiber, far infrared fiber, etc. These fibers have low thermal conductivity, so they have
Good thermal insulation performance.
What is far infrared fiber?
Far infrared ray is an electromagnetic wave with a wavelength of 3 ~ 1000 micron, because it can interact with moisture.
Particles and organic matter produce * * * vibration with good thermal effect. Among the far infrared fibers, there are some
Far infrared ceramic (functional metal oxide) powder, at normal body temperature.
It can emit far infrared rays. Medical research shows that far infrared rays can not only act on the human body surface.
On the surface, it can also act on the internal tissues of the human body, thus effectively promoting the blood circulation of the human body and improving it.
Physiological microcirculation.
What is Leica?
Some underwear is made of cotton and lycra, so readers often ask recently: What is lycra?
Card? According to experts, Lycra is a kind of spandex elastic fiber thinner than hair, and
Mixing cotton yarn into the fabric of thermal underwear can mainly give thermal underwear good stability.
Sex is not deformation. But its warm-keeping effect is not significant.
Thermal underwear is a new thing in our life and has no place in the field of clothing products.
Doubt is ahead to some extent. From the point of view of keeping warm, it is suitable for people's thin clothes.
The pursuit of. From the perspective of medical care, it has brought good news to thousands of patients in Qian Qian. But I think
It is unrealistic to expect an underwear to cure all diseases for the winter. We are in tune.
It is believed that with the continuous development of eco-membrane technology and functional fiber technology, thermal underwear will return to people.
Classes will be warmer and healthier.
