What is the thermal effect of thermal underwear?

The first category: pure cotton underwear

The most traditional single-layer underwear is soft and breathable, but it is more suitable for spring and autumn because of its light texture.

The second category: fiber thermal underwear.

Cotton, wool, acrylic, polyester and other fabrics are mostly used, and flocs such as cotton, wool and camel hair are used as fillers in the interlayer. It has good air permeability and moisture conductivity; The disadvantage is that it looks bloated and heavy.

The third category: space cotton thermal underwear

Its fabric is made of cotton, wool and chemical fiber. The inner floc is plated with a metal film. Its advantages are relatively warm and radiation-proof; The disadvantage is that the air permeability and moisture conductivity are poor, and it has a silky sound when worn.

The fourth category: thermal underwear with ICCP interlayer.

It uses cotton, wool, silk, lycra and other fabrics, and the ICCP material in the interlayer has also developed from the initial non-porous to the current porous mesh membrane. The fixation between fabric and interlayer can also be bonded by glue until it is compounded by special process.

Category V: Comfortable and healthy thermal underwear

These products claim to contain far-infrared fibers and more than 20 kinds of trace elements, and far-infrared rays can transform energy in the body and regulate the body's immunity.

Category VI: silk thermal underwear

Traditional silk thermal underwear, commonly known as silk cotton-padded jacket, is green and healthy, light and soft, smooth and warm. In addition, it has strong thermostability, air permeability and moisture permeability, so it is warm, light and comfortable to wear, and the silk cotton-padded jacket can prevent mites, bacteria and mold.

Extended data;

Underwear material suitable for winter wear;

1, cotton: it is easy to be dyed in various colors. Cotton fiber is breathable and absorbs sweat, and it is the main material of most clothes. But the softness is not as good as that of mulberry silk, and it lacks the health care function of silk.

2. Mulberry silk: commonly known as silk, it is known as the "queen" in textiles. People accept it not only because it is beautiful, light, soft and smooth, but also because it has the unique health care function, moisture permeability, antistatic property, moisture absorption and air permeability of silk underwear, which is conducive to regulating the temperature and humidity of the human body.

3. Chemical fiber: Chemical fiber fabrics are easy to wear, soft, crisp and colorful, and have always been loved by people. However, they are irritating to the skin.

Because the raw materials of chemical fiber fabrics are extracted from high molecular compounds or nitrogen-containing compounds such as coal, oil and natural gas, some of them are likely to become allergens. In addition, this kind of fabric has poor air permeability and hygroscopicity, which affects sweat evaporation and skin respiration.
