 Full text | Abstract: This paper presents the modification of a technology for the production of melt-blown nonwoven filtration materials. A method of introducing a bioactive agent during melt-blown production was developed. Bioactive properties were obtained by means of biologically active modifiers. As a result of microbiological tests, it was proven that the addition of modifiers at the initial technological stage does not give satisfactory results because of difficulties in combining the modifier particles with the polymer granulate, as well as the negative influence of the temperature of the molten polymer on biocidal properties. The technological research was concerned with establishing a method of introducing various biocidal agents at different points of melt-blown production. To this end, modification of a laboratory station head and take up device was performed, and then the process parameters were optimised with special consideration for polymer consumption and polymer blow temperature. The results of the microbiological tests confirmed the usefulness of nonwoven filtration materials for the construction of respiratory bioprotective devices due to their bioactive properties. |
