1. one kind for utilizing the equipment of the long filament continuous manufacturing non-woven net of being made by thermoplastic synthetic material, there is a spinneret (1), a cooling chamber (2), a draw unit (4) and one for long filament being deposited to the precipitation equipment of described nonwoven webWherein two kinds or more kinds of different molten polymer can be fed into spinneret (1), and be provided with one for merging the device of described different molten polymers, to make, from the spinneret opening of spinneret (1), discharge bicomponent filament or multicomponent filamentsWherein, described cooling chamber (2) is apart from spinning plate (10) the certain distance setting on spinneret, described cooling chamber (2) is arranged on the below of spinning plate (10), a monomer-type getter device (27) is arranged between spinning plate (10) and air feed cabin (8), described monomer-type getter device (27) has a suction muffler (28), at least one induced-draught fan (29) is connected on described suction muffler (28), described suction muffler (28) has a first air-breathing slit (30) that is positioned at this suction muffler bottom, this first air-breathing slit leads to the formingspace of described long filament, described suction muffler (28) also has a second air-breathing slit (31) on the top of this suction muffler,And cooling chamber (2) is divided at least two cooling chamber regions (2a, 2b), at bicomponent filament described in these cooling chamber regions or multicomponent filaments, come in contact from the plant air with different temperatures and/or different air humiditys respectively;

  • Wherein the ratio of the length in the length in upside the first cooling chamber region (2a) and downside the second cooling chamber region (2b) is 0.15 to 0.6,And, the speed that plant air enters in downside the second cooling chamber region (2b) from upside the first cooling chamber region (2a) is 1.0 meter per second to 1.6 meter per seconds, and the speed that plant air enters in described draw unit (4) or center-aisle from downside the second cooling chamber region (2b) is 1.5 meter per second to 2.1 meter per seconds.
