from each nozzle are combined and drawn together in a drawing unit then they are deposited on a screen like conveyor belt moving horizontally the resulting loose nonwoven is presolidified in a calender with two steel rolls under a pressure of 1 5 metric tons at a rate of 25 m min both rolls are heated to 100 u00b0 c and the bottom roll has an engraved surface then the nonwoven is sprayed with a silicone finish and finally solidified in a continuous oven at 180 u00b0 c by softening the binding filaments variation coefficient of the surface mass less than 5 measured on a 10 u00d7 10 cm square tensile strength in the longitudinal direction untufted 200 n 5 cm tested according to european standard 290 73 t3 elongation at break in the longitudinal direction untufted 31 tested according to european standard 290 73 t3 tensile strength in the transverse direction untufted 180 n 5 cm tested according to european standard 290 73 t3 elongation at break in the transverse direction untufted 35 tested according to european standard 290 73 t3 tear propagation resistance in the longitudinal direction 170 n tested according to din 53 589 sheet 3 the following characteristics are obtained after tufting with an insertion density of 5 32 34 tensile strength in longitudinal direction tufted 250 n 5 cm tested according to european standard 290 73 t3 elongation at break in the longitudinal direction tufted 65 tested according to european standard 290 73 t3 tensile strength in the transverse direction tufted 180 n 5 cm tested according to european standard 290 73 t3 elongation at break in the transverse direction tufted 65 tested according to european standard 290.
