What types of thermal underwear are there?

1. Pure cotton underwear. The most traditional single-layer underwear is soft and breathable, but due to its thin texture, it is more suitable for spring and autumn.

2. Underwear made of fibrous thermal insulation materials. Cotton, wool, acrylic, polyester and other fabrics are mostly used, and cotton, wool, camel hair and other flakes are used as filling materials in the interlayer. The advantage is that it has good breathability and moisture conduction properties; the disadvantage is that it looks bulky and heavy when worn.

3. Space cotton thermal underwear. Its fabrics are made of cotton, wool, chemical fiber, etc., and the inner interlayer wadding is coated with a metal film. Its advantages are that it is relatively warm and radiation-proof; its disadvantages are that it has poor breathability and moisture conductivity, and it makes a silky sound when worn.

4. Thermal underwear with ICCP material in the interlayer. It uses cotton, wool, silk, Lycra and other fabrics, and the ICCP material in the interlayer has also developed from the original non-porous to the current mesh-like film with holes. The fixation between the fabric and the interlayer has also been changed from using glue to being combined together using a special process.

5. Comfortable and health-care thermal underwear. Such products claim to contain far-infrared fiber and more than 20 trace elements. Far-infrared rays can convert energy in the body and mediate the body's immunity.

Selection tips

1. When buying thermal underwear, you should choose rationally and compare the cost performance of the products. Don’t think that more expensive is better.

2. Treat and identify thermal underwear product advertisements correctly. The basic function of thermal underwear is to keep warm and comfortable. Some advertising content lacks scientific basis. Do not blindly believe in so-called high-tech concepts such as cards.

3. When choosing thermal underwear, the fabric should be soft and comfortable, light in weight, good in elasticity and warm.

4. The thermal insulation of thermal underwear is inversely proportional to the air permeability (fabric density). In order to deal with various traps in the thermal underwear market, you should look, touch, listen, try and choose when purchasing thermal underwear.

Take a look at the fabrics: Various thermal underwear on the market are divided into three categories: high, medium and low. The fabrics used include 40-count cotton, 32-count cotton, polyester-cotton, purified fiber, etc. Among them, the products that use more than 40 thread count cotton for both the inner and outer layers are the best. They have good softness, fineness, breathability, and gloss. They also have no pilling after washing and no lint after long-term wear. The phenomenon of clothes becoming silky.

Second, feel: High-quality underwear has high manufacturing requirements for the thermal insulation layer. High quality thermal insulation lining using microfiber, use this. Garments made of this kind of lining are both soft and comfortable and have good thermal insulation properties. Therefore, if you hold it with your hands, a product that feels smooth and has no foreign body feeling indicates that it uses better materials, the carding and compounding process of the intermediate is also more advanced, and the wearing performance is also better.

Three listening sounds: Generally, old-fashioned thermal underwear products use an ultra-thin hot-melt film (commonly known as PVC plastic film) in the thermal lining to enhance wind resistance, but this product It is easy to make a "rustling" sound when worn, and the breathability is affected, giving a "hot feeling". At the same time, the friction between the plastic film and the thermal fiber is easy to accumulate static electricity, and it is easy to make an obvious "crackling" sound when putting it on and taking off. The new generation of thermal underwear uses new materials and new processes to replace hot-melt films, which basically overcomes the above shortcomings. When purchasing, just shake it gently or rub it gently with your hands, and listen for a "rustling" sound to judge.

Four tests of elasticity: The new generation of thermal underwear is developing towards multi-functional functions such as health care and antibacterial. At the same time, it pays more attention to the development of new products that conform to the contemporary aesthetic concepts of human body curves. One of the major breakthroughs is to make thermal underwear with excellent of resilience. This kind of underwear has Lycra added to the fabric and base material, and the inner lining core layer is made of highly elastic polymer. Although the price is significantly higher than ordinary products, when worn on the body, it feels good against the body and does not feel bloated. The joints can also move freely.

Five selected brands: A piece of underwear, from the selection of raw materials, spinning, weaving, dyeing, compounding, sewing to factory inspection, all links and processes need to be strictly controlled, so that the product can keep warm Various indicators such as efficiency, breathability, antibacterial, and elasticity all meet the standards. Therefore, when consumers purchase thermal underwear, after considering the performance-price ratio of the product, they should focus on purchasing products from companies with outstanding strength, brand, and good reputation to ensure that they have no worries after purchase.

Thermal underwear

Six try-on: Just look at it with your eyes. It is dangerous to buy without trying it on. It is still very rewarding to sincerely communicate with the shopping guide ladies, because the shopping guide ladies in well-known brand stores or counters have generally received professional training and can give you some selection suggestions.
