If the wearable textiles cannot quickly guide sweat and heat to the external environment of the fabric, the human body will not only produce uncomfortable feeling such as stickiness and sultry heat, but also easily provide excellent living conditions for bacteria and increase the risk of heat stroke, which seriously threatens human health. Therefore, in order to enable textiles to meet consumers' requirements for summer clothing or sportswear, as well as the needs of athletes, soldiers or industrial workers for cool and comfortable clothing under high temperature and high humidity conditions, hygroscopic cool textiles have emerged as the times require, and research and development Moisture-absorbing cool textiles are an inevitable trend for apparel textiles in summer and in extreme environmental conditions.

Hygroscopic and cool textiles mainly refer to textiles with good moisture absorption, moisture conduction and heat dissipation properties, which can quickly cool down and form a dry microclimate area around the wearing body, which can still keep human skin cool and comfortable in a high temperature and high humidity environment. of textiles.
