First, look at the fabric: the quality of the underwear inside and outside is the key to the comfort of the underwear.

At present, the thermal underwear in the market can be divided into three categories: high, medium and low grade. The fabrics used include 40 cotton, 32 cotton, polyester cotton (cotton content between 30%~40%), purified fiber and so on. Among them, 40 or more cotton products are superior in the inner surface layer, and their softness, fineness, air permeability and gloss are all good, and they will not pilling and pilling after washing.

Two to listen to voice: old style thermal underwear is used in the thermal lining with an ultra-thin hot-melt film (commonly known as PVC plastic film) to enhance the wind resistant capacity, but this product is easy to make rustle when wearing, and permeability is affected, there will be dry heat, easy to electrostatic.

The new generation of thermal underwear products replace the hot-melt film with new materials and technology, which basically overcomes these shortcomings.

When you purchase, you should gently shake or rub gently with your hands, and listen to whether there is any rustle.

Three hand feeling: high-quality underwear is used in the middle insulation layer to use ultra-fine fiber (diameter less than 1.2 silk) weaving, the garment is soft and comfortable, and has good thermal insulation performance. When kneading with the hand, it feels soft and without foreign body sensation.

The process of carding and compounding of intermediates is also advanced, and the surface and intermediate of garment are of strong sense of unity and better wearing performance.

Four, try to be flexible: the new generation of thermal underwear is developing to many functions, such as health care, antibacterial and so on. More attention should be paid to developing new products that conform to the contemporary aesthetic concept of human body curves. One of the major breakthroughs is that the thermal underwear has excellent resilience.

This underwear has been added to Lycra in fabric and raw materials, and the inner liner core layer adopts high elastic polymer. Although the price is higher than that of ordinary products, it has a good feeling of close fitting and no bloated feeling, and the activities of all joints are very comfortable.

Fifthly, we should choose brands: underwear produced by famous enterprises, from raw material selection, spinning, weaving, dyeing, compounding and sewing to factory inspection, all links and processes need to be strictly checked, so that all indexes such as thermal insulation, air permeability, antibacterial and elasticity of products meet the standards.

Therefore, consumers should first look at the price when choosing warm underwear. At the same time, they should pay attention to the purchase of products with strong strength, brand excellence and reputable enterprises, so as to ensure that they have no worries after purchase.
