Main Function of Tissue Forming Felt

1. Carrying and transmitting paper web: It receives the thin pulp (0.2%~0.5% concentration) thrown out from the forming roll or cylinder mould, serves as a carrier to support the newly formed ultra-thin wet paper sheet (10-20 gsm), and smoothly feeds it into the press section.

2. Vacuum assisted dehydration: Combined with a vacuum box or vacuum suction roll, quickly remove free water.

Material and Structure of Tissue Forming Felt

(Multi Layer Laminated Needle Press Felt)

1. Surface fiber layer (Paper Side): in direct contact with the paper sheet
Material: Imported ultra-fine denier nylon/polypropylene fiber (1.7~3.3 dtex)
Requirement: Extremely delicate, smooth, seamless, and without felt lint

2. Middle support layer: provides elastic and permeable channels
Material: coarse nylon, high elasticity fiber
Function: High rebound, compression resistance, large water holding capacity

3. Base mesh layer (bottom mesh, BOM): skeleton, determines dimensional stability
Material: Nylon monofilament (warp: 0.15~0.4mm; weft: ply yarn)
Structure: Circular weft weight flat, 1/1 plain weave, multi-layer composite
Key: seamless (circular), high strength, low elongation, no deformation

4. Bottom fiber layer (Machine Side): wear-resistant, water conducting
Material: Wear resistant nylon
Function: Wear resistant, easy to clean, and moisture resistant

High Dewatering Anti-Contaminant Base Mesh	High Resilience Base Mesh

Suitable Tissue Paper Type

Crescent Former Tissue Machine (High Speed)
The press felt is wrapped around the forming roll and forms a pressure zone with the copper mesh. The pulp is dehydrated and formed under centrifugal force and vacuum
Requirements: High smoothness, high dehydration, high stability, anti contaminant

BF/Traditional Vacuum Cylinder Mould Machine
Felt wrapped vacuum cylinder mould, vacuum suction dehydration
Requirements: high filtration, high rebound, and compression resistance
