The fabrics of clothing such as casual wear and sportswear require both good comfort, and during activities, once sweating occurs, the clothing will not stick to the skin and produce a feeling of cold and wetness. So consumers put forward new requirements for fabrics with moisture wicking function.
Natural fiber-good moisture absorption performance, comfortable to wear. However, when the human body sweats slightly, the cotton fiber will swell due to moisture absorption, and the air permeability will decrease and stick to the skin, hindering the body's activities, and its water distribution speed is also slower, causing a feeling of coldness and dampness to the human body.
Polyester fiber-one of the largest varieties of synthetic fibers today, it has high breaking strength, good abrasion resistance, and resistance to insects, so it is loved by people. However, polyester fiber is hydrophobic, its moisture absorption and perspiration performance is poor, the electrostatic effect makes it easy to be stained, the surface of the fabric is easy to fuzz and pilling, and the wearing comfort is greatly reduced.
As the baking temperature increases, the moisture absorption and quick-drying effect of the fabric is significantly improved. After finishing polyester fabrics and polyester-cotton fabrics, the moisture absorption and quick-drying effect is compared with that of unwashed fabrics. The increase of the capillary height and the decrease of the moisture evaporation rate gradually decrease, indicating that as the baking temperature increases, the durability performance increases. This is because as the temperature increases, the finishing agent can be better produced with the finished fabric. Co-crystallization, thereby firmly adsorbing on the surface of the fiber, so that the moisture absorption and quick-drying performance and durability of the fabric after the moisture-absorbing and quick-drying finishing can be improved. However, it can be seen from the breaking strength retention rate in the table that with the increase of temperature, the strength of polyester fabrics and polyester-cotton fabrics also continues to decrease. Comprehensive considerations, the finishing process is generally controlled at 190°C
