How Does Thermal Underwear Work?
The material structure of thermal underwear is composed of inner and outer fabrics and intermediate composite layers. The middle composite layer is the key to thermal underwear.
Initially, the composite layer of thermal underwear used agricultural film technology, using the excellent heat insulation and wind resistance of the plastic film, the formation of general textile materials to achieve thermal efficacy.
A number of small holes are punctured into the film using a technique called acupuncture, and fibers (known as Antarctic cotton) are combined on both sides of the film. The composite layer is then bonded to the inner and outer knitted fabric using a binder to form the material for thermal underwear.
Nowadays, the material of thermal underwear has been changed to special chemical fiber, mainly ultrafine, fiber, hollow fiber, far infrared fiber and so on.
These fibers have low thermal conductivity, so they have good thermal insulation performance.
Medical research shows that far infrared rays can not only act on the surface of the human body, but also on the internal tissues of the human body, so as to effectively promote human blood circulation and improve physiological microcirculation.
Thermal underwear is a new thing produced in our life, which has certain advanced nature in the field of clothing products.
From the perspective of warmth, it ADAPTS to people’s pursuit of lightweight clothing.
