Method and device for production of linear fibre formation comprising nanofibres

摘要

The invention relates to a method for production of a linear fibre formation comprising a linear fibre core, on which in a spinning space of an electric field of high intensity the nanofibres produced through electrostatic spinning of polymer matrix are deposited. Through the spinning space of the electric field at least two straight segments of the linear fibre core are guided, between which the core outside the spinning space of electric field is guided at least along a section of circumference of the guiding cylinder, while in projection into a plane being tangential to circumference of the guiding cylinder and passing the respective segment of the core, this segment of the core and longitudinal axis of the guiding cylinder contain an acute angle. The invention also relates to a device for production of a linear fibre formation comprising a linear fibre core, on which there are deposited the nanofibres produced through electrostatic spinning of polymer matrix in a spinning space of an electric field induced between a spinning electrode and an collecting electrode. At the same time in the active chamber there is created guidance of the linear fibre core, which comprises a guiding cylinder arranged outside the spinning space of the electric field, while through the spinning space of the electric field at least two straight segments of the linear fibre core are guided. Between them the core is guided at least on a section of circumference of the guiding cylinder, and in projection into a plane being tangential to circumference of the guiding cylinder and passing the respective segment of the core, it with longitudinal axis of the guiding cylinder contain an acute angle.
