\n1.<\/u>Thermal Insulation Principles and Applications in Fibers<\/u><\/p>\n
Low thermal conductivity materials are porous structural materials with porosity levels often exceeding 90%. Because of their highly porous structure, the non-moving air trapped inside the material helps provide low thermal conductivity and lightweight properties. In many cases, the thermal conductivity can reach below 0.02 W\/mK.<\/p>\n
When these low thermal conductivity materials are applied to fibers, they can reduce heat or temperature transfer through fibers and textiles, thereby improving thermal insulation performance.<\/p>\n
\n2.<\/u>Thermal Conductivity of High Thermal Insulation Fiber Fabrics<\/u><\/p>\n
Thermal conductivity is a measurement used to evaluate a material\u2019s ability to conduct heat. It indicates how much heat can pass through a material per unit area and per unit time during heat transfer. The unit of thermal conductivity is W\/(m\u00b7K).<\/p>\n
The higher the thermal conductivity, the better the material is at conducting heat, meaning heat can be transferred or dissipated more quickly.<\/p>\n
In contrast, materials with lower thermal conductivity provide better insulation performance because they can block heat transfer and effectively reduce heat loss. This makes them suitable for thermal insulation and insulating material applications.<\/p>\n

Through its independently developed dispersion technology, KCI processes low thermal conductivity materials into functional masterbatch for fiber applications. These masterbatches can be used in polyester fibers, nylon fibers, and other textile materials.<\/p>\n
When 5\u201310% high thermal insulation masterbatch is added to fiber spinning raw materials, the produced fibers contain low thermal conductivity materials and can effectively reduce the thermal conductivity of the fibers. Once these fibers are woven or processed into fabrics, the overall thermal insulation performance of the fabric can be significantly improved.<\/p>\n
