High Thermal Conductivity
High-Density Polyethylene Yarn (HDPE Yarn) is a textile yarn made by melting and stretching high-density polyethylene (HDPE) chips. Its material structure gives it excellent thermal conductivity. When the human body comes into contact with polyethylene yarn, the yarn efficiently conducts heat from the skin’s surface, creating a cooling effect. This process is known as heat conduction. As the yarn rapidly absorbs the heat from the skin and transfers it into the air, it provides a cool sensation.
Low Moisture Absorption
Polyethylene yarn has very low moisture absorption, typically much lower than natural fibers like cotton. Due to its poor moisture absorption, HDPE yarn remains relatively dry in low-humidity environments, reducing discomfort caused by excess moisture. In such conditions, garments made from polyethylene yarn feel cooler because they do not absorb large amounts of sweat, which helps maintain a lower level of humidity on the skin’s surface.
Hydrophobicity and Breathability
The hydrophobic nature of polyethylene yarn prevents it from easily absorbing sweat, allowing sweat to evaporate quickly and reducing any sticky feeling. Additionally, the structure of polyethylene yarn itself allows for good breathability, enabling air to flow freely through the material. This enhances the cooling effect. When worn, the airflow helps dissipate heat, keeping the skin's surface feeling drier and cooler.
Fiber Fineness and Surface Structure
The fineness and surface structure of polyethylene yarn also affect its cooling performance. Finer fibers reduce friction against the skin, increasing comfort. Additionally, the smoothness of the fiber surface enhances air circulation, further boosting the cooling effect.
Application
Summer Clothing: Due to its cooling properties, polyethylene yarn is commonly used in the production of summer sportswear, outdoor gear, work uniforms, etc. These garments typically require breathability, quick-drying, and cooling functions, which polyethylene yarn perfectly fulfills.
Mattress fabric: Products like mattress fabric and mattress cover. The cooling properties of polyethylene yarn provide added value in these applications, ensuring a more comfortable sleeping.Related Applications
