  • Device for the continuous production of a nonwoven web
    Publication number: 20060040008
    Abstract: Device for the continuous production of a nonwoven web from filaments made from a thermoplastic synthetic, with a spinning nozzle, a cooling chamber, a stretching unit and a depositing device for depositing the filaments to the nonwoven web. Two or more different polymer fusions can be fed to the spinning nozzle, and a device for merging the different polymer fusions is provided such that bi-component filaments and multi-component filaments can exit from the spinning nozzle openings of the spinning nozzle. The cooling chamber is divided into at least two cooling chamber sections in which the bi-component filaments and multi-component filaments can be respectively acted upon by process air with different convective heat conduction means.
