Professor explained how to choose clothes scientifically 07:00

The choice of clothing plays a key role in ensuring comfort and protection of a person. The properties of fabrics determine their ability to protect against cold, heat, wind and moisture. Doctor of Physical and Mathematical Sciences, Professor of RTU MIREA Roman Shamin told socialbites.ca.

“Thermal conductivity, water resistance, breathability, moisture and moisture-absorbing properties, durability, resistance to ultraviolet radiation – these factors should be taken into account when choosing clothing. Modern technologies make it possible to create materials that combine a variety of useful properties, provide maximum comfort and protection in any weather conditions,” he explained.

According to the professor, materials with low thermal conductivity (thermal insulators) retain heat better, making them ideal for cold weather.

“Examples include wool, down and synthetic insulation. Wool is a natural insulator and absorbs moisture well without losing its heat-saving properties. Down is light and warm, providing thermal insulation with minimal weight. Cheaper alternatives such as polyester are also moisture resistant. The ability to conduct or repel water is critical for garments worn in wet weather,” Shamin added.

Waterproof materials keep the inner layer of the suit dry. These include: Gore-Tex (breathable membrane), neoprene (used in diving suits), nylon and waterproof polyester.

“Breathable materials allow the skin to breathe and prevent overheating. These are: cotton and linen (natural materials that allow air to pass through well and absorb sweat). Bamboo has excellent breathability and absorbency properties, which is why it is used in sportswear. Moisture-wicking materials allow moisture to evaporate quickly. Thus, merino wool absorbs moisture and remains dry to the touch, making it perfect for thermal underwear. Fabrics with moisture-wicking properties (for example, the previously mentioned polyester) are used in sportswear to effectively remove moisture from the skin’s surface and evaporate it quickly,” he emphasized.

Durability is important for clothing designed for outdoor activities and harsh conditions. Abrasion-resistant materials ensure a long service life. These include: Kevlar (a tear-resistant material used in protective camouflage); nylon is light and durable, often used for sewing tourist and sports clothing.

“UV resistance is another important aspect of skin protection and cancer prevention. UV-resistant materials prevent burns and reduce the risk of skin diseases. That is why special UV-protective fabrics (e.g. Garden) are used in beach and sportswear to protect from the sun,” Shamin concluded.
