What is the best material for thermal underwear? Recommended thermal underwear

Thermal underwear is something that everyone wears in autumn and winter. Thermal underwear has a very good warming effect. Wearing it innermost can play an invisible warming role. Thermal underwear is generally very close-fitting, and the choice of material is very important.

1. Wool: Wool fiber is soft and elastic, has strong moisture absorption and good warmth retention. Because wool is naturally curly, it can form many stagnant air zones as a barrier, which has good warmth retention. Wool has very good stretchability and elastic recovery, and has a special hair scale structure and excellent bendability, so it also has good appearance retention.

2. Bamboo charcoal: The biggest difference of this fiber is that each bamboo charcoal fiber has a honeycomb microporous structure that runs through the inside and outside. This unique fiber structure design can make the functions of bamboo charcoal 100% come into play. The birth of this multifunctional bamboo charcoal fiber is a revolutionary innovation in textile multifunctional raw materials.

3. Modal: The dry strength of modal fiber is close to that of polyester, and its wet strength is much higher than that of ordinary viscose. Its gloss, softness, hygroscopicity, dyeability and dyeing fastness are all better than those of pure cotton products. The fabric made of it shows a silky luster, has a pleasant soft touch and drape, and excellent wear resistance. It is an ideal close-fitting fabric and health care clothing product, which is beneficial to human physiological circulation and health.

4. Lycra: Lycra can be freely stretched 4 to 7 times, and quickly returns to its original length after the external force is released. It cannot be used alone, but can be interwoven with any other artificial or natural fiber. It does not change the appearance of the fabric, and is an invisible fiber that can greatly improve the performance of the fabric. Lycra has outstanding stretchability.

5. Spandex: Spandex is generally not used alone, but is mixed into fabrics in small quantities. This fiber has both rubber properties and fiber properties. Most of them are used for core-spun yarns with spandex as the core yarn, called elastic core-spun yarns. The main features of this yarn are: first, it can obtain a good feel and appearance, and the outer fiber composed of natural fibers has good moisture absorption; second, only 1-10% of spandex filaments can produce high-quality elastic yarns; third, the elasticity percentage control range is from 10% to 20%, and different elasticity values ​​can be selected according to the purpose of the product.

6. Nylon: Nylon has good strength and wear resistance, ranking first among all fibers, and its durability is excellent. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under small external force, so the fabric is easy to wrinkle during wearing. During wearing and use, you must pay attention to the conditions of washing and maintenance to avoid damaging the fabric. Nylon fabric is a light fabric, which is only ranked after polypropylene and acrylic fabrics among synthetic fiber fabrics. Therefore, it is suitable for making mountaineering clothes, winter clothing, etc.

7. Combed Cotton: Combed Cotton - Use a combing machine to remove the shorter fibers (about 1cm or less) from the cotton fibers, leaving longer and neater fibers. Fabrics made from combed cotton yarn have a higher quality level in terms of texture, washability and durability. Cotton fibers have high strength, good wrinkle resistance, but poor stretchability; good heat resistance, second only to linen; poor acid resistance, but resistant to dilute alkali at room temperature; good affinity for dyes, easy dyeing, complete color spectrum, and brighter color.

8. Polyester fiber: Polyester fiber is made of polyester (PET, polyethylene terephthalate) as the main raw material, with certain functional masterbatch added. The product density is 136g/cm3, and it is soluble in solvents such as phenol-tetrachloroethane and o-chlorophenol. It has very low hygroscopicity, is acid-resistant, has high chemical stability compared to polyamide, and has good light resistance. The fiber does not become brittle or deformed within the temperature range of -40℃-+250℃, and each fiber is independent and provides huge cohesive force.

9. Kapok: Kapok thermal underwear is a green, natural and environmentally friendly underwear product, with the characteristics of light weight, softness, smooth surface, bright colors, anti-static, and not easy to tangle. Kapok thermal underwear is favored by consumers because of its characteristics of light weight, softness, smoothness, bright colors, anti-static, not easy to tangle, moisture absorption and moisture conduction, no mold and moth, acid and alkali resistance at room temperature, and green, natural and environmental protection.

1. Antarctic thermal underwear

Nanjiren thermal underwear has double-layer thickness on the chest, back, elbows and knees, which is more warm, and the lining is velvet-lined, comfortable and warm, protecting the knees and effectively preventing rheumatic pain. The soft and breathable Nanjiren thermal underwear has a velvet-lined and thickened lining design, which is very comfortable and warm to wear in winter. The fashionable print design can also be worn outside in winter.

2. Silkbird thermal underwear

A set of comfortable thermal underwear can not only help you resist the cold, but also make you feel more comfortable. Fiberbird thermal underwear has been well recognized by consumers for many years, and its brand products have a high market praise rate. The operation of the online flagship store has given more consumers a way to buy, and the discounts of different packages allow consumers to easily buy cost-effective products.

3. Catman thermal underwear

The "Japanese heating fiber" proposed by Maoren International does not conform to consumers' inherent perception of "warmth" and requires a lot of complicated explanations and education. The hype about "Japanese heating fiber" does not conform to the positioning of "fashion underwear". Australian wool is a concept of warmth that consumers can easily accept and is consistent with consumers' inherent perception of warmth. Therefore, Chengmei denied the practice of promoting "Japanese heating fiber" and believed that by mentioning the information of "Australian wool", it would be enough to let consumers know that Maoren Thermal Card is a warm underwear.

4. Tingmei thermal underwear

The inner layer of Tingmei's "spiral heating" slimming and warm underwear uses ultra-fine heating fibers to form a close-fitting energy-gathering layer, which gathers the heat conducted from the body surface and releases it to the skin surface to keep warm and promote blood flow. The ultra-fine hollow fibers ensure that human sweat can be smoothly discharged from the gaps in the fibers. The outer layer uses an ultra-fine pore structure to form a heating isolation frame, which uses the principle of vaporization heat circulation flow to isolate cold air from entering, and quickly heats up to 8°C.

5. Red Bean Thermal Underwear

Hongdou thermal underwear is made of new materials such as bamboo fiber, corn fiber, milk silk, air conditioning fiber, etc. It is not only environmentally friendly and comfortable, but also has health care functions. Moreover, Hongdou underwear is deeply loved by consumers for its novel style and exquisite materials.

People's common thermal underwear fabrics are divided into two categories, natural fibers and chemical fibers (artificial fibers).

1. Natural Fibers

Natural fibers are specifically textile fibers that grow naturally or are obtained from artificially cultivated animals and plants, including cotton, linen, silk, wool, etc.

2. Chemical fiber

Chemical fiber refers to fibers with textile function that are synthesized by chemical means (melting, spinning) with high molecular weight compounds as raw materials, including polyester fiber (polyester), polyamide fiber (nylon or nylon), polyacrylonitrile fiber (acrylic fiber), etc. It is better to use natural fiber for close-fitting thermal underwear, which is not only warmer, but also less likely to cause skin allergies, itching and other symptoms.

Thermal underwear includes 37° constant temperature self-heating and more fleece-lined ones, which are the most commonly worn thermal underwear in winter. Generally speaking, if you are not very afraid of cold, you can use 37° constant temperature thermal underwear. This kind of underwear is close-fitting and not bulky, and it is very easy to match with clothes. If you are very afraid of cold, it is better to choose thick thermal underwear. This kind of underwear does not penetrate the wind and has a better warming effect in the cold winter!
