Problems solved by technology

[0003] As we all know: natural fibers, such as cotton, have good hygroscopicity and are comfortable to wear, but when people sweat a little, the cotton fibers will swell due to moisture absorption, and their air permeability will decrease and stick to the skin. The divergence speed is also slow, which creates a cold and wet feeling to the human body; synthetic fibers, such as polyester, have low water absorption and poor moisture permeability. Due to the accumulation of static electricity, it is easy to cause entanglement when wearing Easily feel stuffy during activities
[0004] Most of the softeners used in the traditional post-dyeing and finishing processing are water-repellent polymer compounds, which make chemical fibers such as Polyester (polyester) or Nylon (nylon) which are non-absorbent fibers more hydrophobic and comfortable to wear The problem of sexual decline
However, general water-absorbing softeners have either too high yellowing or insufficient softness.

Description

technical field [0001] The invention relates to a moisture-absorbing and sweat-wicking agent and a preparation method thereof, belonging to the field of textile materials. Background technique [0002] In recent years, people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics. With the increase of people's outdoor activities, the trend of mutual penetration and integration of casual wear and sportswear is also It is increasingly favored by consumers. The fabrics of this type of clothing require good comfort, but also require that once sweating occurs during activities, the clothing will not stick to the skin and produce a cold and damp feeling. Therefore, new requirements for moisture absorption and perspiration are put forward for the fibers of the fabric. [0003] As we all know: natural fibers, such as cotton, have good hygroscopicity and are comfortable to wear, but when people sweat a little, the cotton...
