1, hygroscopicity

Moisture absorption refers to the ability of an object to absorb or release gaseous water in the air. Specifically, it refers to the ability of clothing materials to absorb sweat and steam discharged from the surface of human skin in time, and transmit them to the other side of the fabric through fibers and release them into the air. The better the performance, the better the hygroscopicity, the drier the human skin, and people will not feel sultry, especially in sultry summer and strenuous exercise.

Among the clothing materials, natural fiber materials have the best hygroscopicity. Because some natural fibers have more hydrophilic groups and some have cavities or capillaries, their hygroscopicity and moisture permeability are mostly good; The yarn is fluffy, and the thinner the material, the more sparse it is. Porous materials have large gaps, which are beneficial to the absorption and volatilization of sweat.

2. Keep warm

The warmth retention of clothing materials refers to the ability of materials to prevent air from passing through, that is, to prevent the heat exchange of air on both sides of materials.

Clothing materials should have proper warmth retention in a certain period of time, such as clothing in winter (including cold areas) should have strong warmth retention to prevent human frostbite; Clothing in summer requires good breathability and proper warmth in spring and autumn, which makes people feel neither too cold nor too hot.

The warmth retention of clothing materials depends on the structure of fibers and yarns, the thickness and density of fabrics, etc. In other words, it depends on how much static air they contain.
