This nonwoven material contains, at least, 50% of synthetic fiber with thickness between 3 and 40 tex and length between 2 and 12 cm. These fibers are joined with needle. After application to the nonwoven material of static pressure of 20 N/sq.cm, it preserves minimal thickness of 2 mm. The offered nonwoven material is especially designed for more efficient removal of perspirations of the seat user. EFFECT: higher efficiency. |
