Mitsubishi Chemical-developed VENTCOOL is Side by side conjugate filament.
which is cubically transformed depending on wet and dry conditions.
Under dry condition, natural crimps of the fiber suppress breathability. When the fiber
moistens due to perspiration, it momentarily elongates to improve breathability,
automatically controlling ventilation within clothes. It is a new-typed high performance fiber.
In addition, it has improved hydrophilicity due to specific fiber modification and keeps
excellent hygroscopic and quick-drying performance even after repeated cleaning.
