[0002] With the continuous improvement of people's requirements for clothing comfort, especially in high temperature environment, consumers have put forward higher demands on the cool feeling, moisture absorption and perspiration performance and air permeability of clothing. Traditional fabric is usually difficult to meet these functions at the same time, especially in sports or outdoor activities, sweat is easy to accumulate on the skin surface, causing discomfort and sticky feeling.

[0003] Polyethylene (PE) fiber has unique advantages in the field of functional fabric due to its high thermal conductivity and 0 moisture regain characteristics. High thermal conductivity enables it to quickly transfer heat, bringing significant cool feeling effect, while 0 moisture regain makes it almost not absorb water, which can quickly conduct sweat and keep dry, and is very suitable for summer clothing and sports clothing. However, PE fiber also has the disadvantages of difficult dyeing and poor high temperature resistance, which limits its wide application in the field of textiles. Therefore, in order to develop a fabric based on PE fiber, which can meet the needs of cool feeling, one-way moisture-conducting, moisture absorption and perspiration, air permeability and color persistence, a PE composite cool feeling one-way moisture-conducting multifunctional fabric is proposed.
