Abstract (en)
[origin: EP2119816A1] The spinneret (140a) is used for manufacturing a web by a spunbond process or meltblown process, and has longitudinal axis (X) that corresponds to the width of the spunbonded or meltblown web. Said spinneret comprises bilobal spinning orifices (141) each having a longitudinal central axis (A). The angle (±) between the longitudinal axis (X) of the spinneret and the longitudinal central axis (A) of one bilobal spinning orifice (141) is between 75° and 87°, in order to improve the cooling and attenuation of the filaments.
