| 发明名称 | Apparatus for spinning fibres and producing a fibrous-containing nonwoven | ||
| 摘要 | The apparatus (1) is used for producing melt-blown fibres (MF). It comprises a die head (104) with several spinning orifices, means (100, 101,102, 103) for extruding at least one melted polymeric material through the spinning orifices of the die head (104) in the form of meltblown filaments (f), and means (104a,104b) for blowing a hot primary gas flow (F1) towards the outlet of the die head (104) in order to draw and attenuate the polymeric filaments (f) at the outlet of the die head, and a drawing unit (105) that is positioned below the die head (104), and that is adapted to create an additional gas flow (F3) that is oriented downstream to further draw and attenuate the meltblown filaments (f). | ||

| 主权项 | 1. An apparatus for making a fibrous-containing nonwoven comprising: a die head with several spinning orifices: means for extruding at least one melted polymeric material through the spinning orifices of the die head in the form of filaments; a drawing unit positioned below the die head, and adapted to create a gas flow that is oriented downstream for drawing and attenuating the filaments; and supplying means for continuously feeding a stream of fibrous material at a position between the die head and the drawing unit, and nearby the filaments. | ||
