Key Equipment
-
Fiber Opening & Blending SystemComplete raw material unpacking, loosening, blending and quantitative feeding to break bundled fibers into loose fiber strands.
-
Carding MachineDouble cylinder and double doffer structure with multiple carding units to card fibers into uniform thin webs. High-precision rollers and bottom plate manufacture guarantee web uniformity.
-
Crosslapper MachineThe crosslapper multi-layer overlays thin webs to control basis weight (60 – 2000g/㎡) and thickness (10 – 200mm), improving uniformity and tensile strength.
-
Hot Air entanglement (Core)High-temperature drying room (150 – 200℃, heated by electricity/gas/heat transfer oil), low-melting point fibers melted to form bonding points at fiber intersections for 3D network shaping.
