manufacturing method of filament using wasted-rope and interior sheet material of automobile thereby

摘要

The object of the present invention is to recycle waste rope to be used as a built-in interior sheet of automobiles. The main structure of the filament manufacturing method utilizing the rope of the present invention comprises: collecting a rope made of polypropylene; Removing foreign matter adhered to the collected rope; Cutting the debris-removed rope; Washing the cut rope; Drying to be within a moisture content of 0-3%; And a sponging step of spunning the rope in a sponge device to form a filament shape. In the step of cutting the rope with the foreign material removed, the length of the cut is 1 to 20 cm And the moisture content is 0 to 3% in the drying step. In the drying step, the drying method is characterized in that the drying is performed using superheated steam in the superheated steam room, In the spongy step, the filament has a thickness of 1-30 deniers at the spongy step of making the filament of the device by sponging (rubbing) the filament. When the rope is sponged (filed) The sponge device comprises a conveyor (2), a motor (8) for moving the conveyor (2), and a rotatable member (3) having a rake (3) A motor 10 for driving the rotating body 4 and an upper rotating body 6 for rotating the rotating body 4. The upper rotating body 6 has an upper rotating body 4 and a rake 3 provided on the rotating body 4, The rake 3 of the rotating body 4 and the rake 3 of the upper rotating body 6 do not collide with each other but overlap each other without overlapping each other. So that the rope is configured to be torn.
