| Popis: | This paper presents the technology of production of synthetic fibrous materials from PET-raw by vertical blowing method. Fibre production by vertical blowing method is accompanied by complex and specific phenomena; therefore, development of new progressive technologies, high-performance machines and units for producing such materials is impossible without process modelling, which can significantly reduce the number of natural tests, cost and designing time and select optimal operating modes. Molten material motion in the melting unit of the hydrostatic type is determined by means of Poiseuille formula. Furthermore, the paper has proven that the melting unit has the greatest impact on process productivity by means of outlet radius and the pressure change of compressed air acting on the molten material surface. Increase in the height of the molten material column in the main cylindrical chamber of melting unit also leads to an increase in process productivity. |
