Double Layer Press Felts include a 1+1 composite structure and a double layer of MD yarn structure.
Description
Double Layer Press Felts include a 1+1 composite structure and a double layer of MD yarn structure. The 1+1 composite structure consists of two-layer base meshes of different thicknesses.
One structure of 1+1 composite double Layer BOM Press Felts
One structure of double-layer of MD yarn double Layer BOM Press Felts
Both of these base meshes can be changed in construction and sizes to suit the requirements of different paper machines.
Double layer felts have the features of high press resistance, good flexibility, permeability and size stability, less elongation, excellent tensile strength.
The felts are also resistant to vacuum marks, blind hole marks, groove marks, etc.
Double-layer BOM felts are used in press types such as groove press, vacuum suction press, multi-press, large-diameter nip-roll press to produce high-grade printing papers, news-prints, technical papers, packaging papers, high-grade paper boards, etc.
