  • METHOD AND APPARATUS FOR MAKING NONWOVEN FABRIC OF CRIMPED SYNTHETIC FIBERS
    Publication number: 20220316097
    Abstract: A method for producing a nonwoven fabric made of crimped synthetic fibers, wherein the synthetic fibers are spun and are deposited on a conveyor as a nonwoven web. The deposited nonwoven web is pre-bonded by means of at least one first hot-air bonding device, wherein a main suction air is sucked from below through the conveyor in the area of fiber deposition. A first suction air is sucked from below through the conveyor in the region of the first hot-air bonding device. The air speed of the main suction air is greater than the air speed of the first suction air.
