Washing thermal underwear has its own distinctive characteristics precisely because of the characteristics of the fabric from which it is made. The creation of thermal underwear became possible thanks to the development of new technologies, which ensured the emergence of a new type of fabric - made from synthetic yarn. It has a multi-layer structure, has increased moisture resistance and the ability to retain heat during active physical activity in low temperatures.

In terms of its technical characteristics, synthetic fabric used in the production of various types of thermal underwear is superior to wool. Thermal underwear is actively used by athletes of such sports as:
- ski disciplines,
- hockey,
- figure skating,
- dancing on Ice,
- water sports athletes.
Thermal underwear is also actively used by professional climbers, Emergency Situations Ministry specialists, as well as people who play sports non-professionally. The properties of the synthetic fabric from which it is made include special properties to retain heat and wick moisture away from the body. Thermal underwear is becoming increasingly popular in everyday life, and is increasingly used by ordinary people who use this type of clothing for everyday wear in the cold season.
Features of heat-saving clothing
Thermal underwear is increasingly gaining popularity in everyday wear. Until recently, this term mainly meant either a sports suit or elements of specialized clothing; now almost all types of outerwear and underwear can have heat-saving functions:
- underwear, including T-shirts, trousers, long johns,
- turtlenecks, leggings, tights,
- children jumpsuits,
- socks, gloves, scarves,
- helmets worn under warm headdresses,
- outerwear.
Good, high-quality thermal clothing requires frequent use and is one of the most popular types of clothing in the cold season. In addition, it is often exposed to unfavorable environmental factors and vigorous friction during physical activity, which means that all this clothing requires special care.
General rules for caring for thermal underwear
The fabric from which thermal insulating and heat-saving clothing is made can be made either only from synthetic yarn, or wool or a little cotton can be added to it. Thermal underwear may differ not only in the composition of the fabric, but also, depending on the purpose of this item of clothing, have its own characteristics and is divided into:
- quick-drying,
- especially thin,
- with enhanced protection against hypothermia,
- designed not only to keep warm, but also to protect from bad weather.
In order for thermal underwear to serve for a long time and at the same time its special heat-saving properties do not decrease over time, you should properly care for such clothing. It is not recommended under any circumstances:
- iron,
- use chemical dyes,
- use stain removers
- boil,
- use the appropriate function of a washing machine or dryer to dry thermal clothing,
- spin in the washing machine,
- dry clothes near sources of open fire,
- dry clothes in the immediate vicinity of heating devices,
- dry on central heating radiators.
Failure to follow these simple recommendations can lead to damage to the fabric fibers and loss of heat-saving properties.
Machine washable thermal underwear
Most types of thermal underwear can be washed in a regular washing machine. Before loading clothes into the machine, you should turn them inside out, check for minor damage and make sure there are no foreign objects in the folds of the clothes or pockets. Small foreign objects can damage not only the laundry being washed, but also cause damage to the equipment itself. Small parts of thermal underwear should be packed in special laundry bags.

Chlorine-containing detergents are strictly not recommended for use.You should avoid using chemicals that can destroy the special properties of synthetic fabric, because it can lose its wonderful properties and become brittle or loose. When washing thermal underwear, it is allowed to use antistatic agents, rinse aids and fabric softeners intended for delicate fabrics. When hand washing, it is recommended to use hand wash soap or detergent for delicate fabrics.
