①Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, the fiber can absorb moisture from the surrounding atmosphere, its moisture content is 8-10%, so when it touches human skin, it can make people feel soft.
②Moisturizing: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low. The cotton fiber itself is porous and highly elastic. Therefore, pure cotton fiber textiles have good moisture retention. Wearing pure cotton clothing makes people feel warm .
③Heat resistance: Pure cotton fabrics have good heat resistance ability. When the temperature is below 110°C, it will only cause the moisture on the fabric to evaporate without damaging the fiber.
④Alkali resistance: cotton fiber has a greater resistance to alkali, and cotton fiber will not be damaged in an alkaline solution.
⑤ Hygiene: Cotton fiber is a natural fiber, and the fabric has no irritation or negative effect in contact with the skin. It is beneficial to the human body when worn for a long time, and has good hygienic properties.
①Thick and Heavy
②Opaque and dull
③It is not easy to dry when exposed to water
④It becomes rough and hard after absorbing a large amount of sweat, which is easy to abrade the skin.
It has the advantages of good elasticity, strong moisture absorption, and good warmth retention. Wool socks can firmly lock the heat inside. They are good items for keeping warm and cold. They are also particularly soft and comfortable, warm and breathable.
①Since wool fiber is composed of protein, it can interact with alkali and be damaged.
②Wool has poor thermostability. If the wool fiber is boiled in boiling water for a long time, the protein will be hydrolyzed, resulting in fiber damage, weakened strength.
③In the rainy season, wool socks are easily get mildewed by absorbing water.
④ Although wool fiber has good elasticity, it is difficult to restore its original shape if the tensile force is too large and the stretching time is too long. To protect the clothing, remember not to stretch too much.
⑤Wool socks have poor sweat-absorbing ability, which may cause the feet to be wet and breed bacteria.
