In the cold winter, looking at the street -type male and beautiful girls, it is still graceful. Is it really not that they are afraid of cold. They mistakenly think they are wearing warm underwear. What is the principle of warmth in warm underwear?Which material is the best effect?What is the principle of warm -keeping underwear?
The material structure of thermal underwear is composed of the inside, outer and intermediate composite layers.The middle composite layer is the key to keeping warm underwear.
Initially, the composite layer of thermal underwear used agricultural film technology, and using the excellent insulation and windshield performance of plastic film to form a warmth effect that it is difficult to achieve in general textile materials.Use acupuncture technology to pierce a certain number of small holes in the film, compose some fibers on both sides of the film (the so -called Antarctic cotton), and then bond the composite layer with adhesives with the inside and outer knitted fabrics together, That is, the material for keeping warm underwear.
Today, the material of warm underwear has been generally changed to special chemical fibers, mainly in ultra -fine fiber, hollow fiber, and far -infrared fibers.These fibers have small thermal conductivity and therefore have better warmth.What is a far -infrared fiber far -infrared ray is an electromagnetic wave with a wavelength of 3 to 1000 microns. It has a good thermal effect because it can resonate with water and organic matter.Among the far -infrared fibers, there are some far -infrared ceramics (functional metal oxides) powder, which can emit far -infrared rays at the normal body temperature of the human body.Medical research shows that because far -infrared rays can not only act on the surface of the human body, but also the internal tissue of the human body, thereby effectively promoting human blood circulation and improving physiological microcirculation.
Some underwear materials are Macaolica, so readers often ask: What is Laica?According to experts, Rica is a spandex elastic fiber that is thinner than the hair. It is mixed with cotton yarn in the fabric of thermal underwear, which can mainly give warm stability to keeping warm underwear, that is, non -deformation.But its warmth is not significant.Warm -keeping underwear is a new thing produced in our lives. It has certain advanced nature in the field of clothing products.
From the perspective of keeping warm, it adapts to peoples pursuit of lightness.From the perspective of health care, it brings the gospel to tens of millions of patients.But it is impractical to want to survive the winter, or expect it to cure all diseases, but it is impractical.We believe that with the continuous development of ecological film technology and functional fiber technology, the warm and healthy backflakes will be warm and healthy.
