Abstract (en)
Within the framework of this dissertation, the multiparametric
process of texturing of the partially oriented (POY) polyamide PA6.6
filament was studied, using the process of apparently "false" twisting
- "false twist" in relation to the newly established structure -
mechanical properties and property relations - process parameters. By
introducing all three parameters as the variables, the temperature of
the heaters, the texture rate and the D/Y ratio of the speed of discs
and yarn speed, changes of the modulus of elasticity of textured yarns
and the determined elasticity limits were observed, which is
experimentally difficult to determine. By examining the boundary
mechanical properties, the behavior of polyamide PA6.6 yarns in the
field of elastic deformations was studied, using intermittent force,
intermittent elongation, relative breaking forces, tearing operation and
variation measure for all of these characteristics.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
