Without sacrificing drainage characteristic this fabric caters to increased demand of higher fabric and filter retention. This design provides higher fiber support index compared to double layer design. This is achieved by providing an extra support shoot (small cross direction yarn) on the topside of double layer construction. This reduces the distance between the two top yarns and provides better support to cellulosic fiber. This fabric is used for making fine quality paper. 16 shaft 2.5 layer provides higher abrasion and increases the running time.
