Summary: The effect of the heath on the PP fibres was studied. The
characteristic thermal constants and the behaviour in the wide temperature
interval up to the thermal decomposition was found out. The influence of
thermal and hydrothermal treatment on the performance properties was
examined. It was established, that the influence of heat, particularly of
hydrothermal treatment, causes dimensional changes which produce
deformations and limit the field of application of PP fbres.
Keywords: polypropylene fibres, thermal characteristics, diferential scanning calorimetry, thermogravimetric analysis, thermal treatment, hydrothermal treatment, performance properties

Summary: Photodegradation of poyester-, polyamide and
polyacrylonitrile fibre samples was investigated. The changes of the
tensile strength and elongation at break of the fibres after determined
exposure time under defined conditions were determined. The results
obtained showed different sensibility of some kinds of the fibres on
photodegradation, particularly on the influence of black dyestuff and
matting agents. Special importance is devoted to the interventions by which
a lower fiber tendency to pilling has been achived. Those interventions
increase the fibres sensibility on photodegradation process. W

Summary: Comparative investigations of some methods for quantitative
determination of preparations and oligomers in polyester fibres were
carried out. Based on the results obtained, the incorrectness of some
methods for determination of preparations (e.g. JUS F.S1.021), caused by
simultaneous considerable dissoliving of oligomers under regulated testing
conditions, is pointed out. The way of correction the results was
established and the most convenient methods and testing conditions
proposed.

Summary: The features of fibres depend considerably on the size and
morphology of molecules from which they are composed. Regarding the size of
polymer molecules, this dependence is not only function of the average
molecular mass, but first of all of its distribution. In the article a
survey of methods for the determination of molecular mass distribution is
given and their comparative advantages and disadvantages discussed. Based
partly on the experiences of the author, the diffculties that can appear in
their realization are indicated.

Summary: The physico-mechanical properties of steel cord and aramid
cord3300/3 dtex poly(p-phenylenterephtalamid) PPTA, Kevlar (DuPont)and
Twaron (Enka), were tested. Adhesion force was determinedbetween brassed
steel cord, impregnated aramid cord andvulcanisate based on natural rubber
and synthetic polyisoprenerubber. The laboratory procedure ASTM D-2229 with
supportinglayers, the so-colled T-test, was used to determine the
adhesionforce. The adhesion force was measured at room temperature, aswell
as after aging for 6 hours at 80, 120 and 160 grade Cel.,and after resting
the T-moulding for 1 hour, 3 hours, 5 hours and24 hours.

Summary: The influence of light (visible and UV-range) on certain
properties of polypropylene fibres has been studied. The isotactic index
was determined as an indicator of stereoregularity of polymere molecules.
Thermal stability loss was estimated throgh DSC and TGA curves and the
fibres morphological changes under the influence of light were determined
by scanning microphotographs.

Summary: It was investigated the influence on distribution of PET
fibres molecular weights produced by adding 0,2 to 0,4% trimethylolpropane
(TMP) as comonomere. The method of fractional disolving in column with the
gradient of solvent (solvent: phenoland nonsolvent: n-hephane) and
temperature, was used. Themolecular weights distribution curves are
determined by the Tung function approximation. Suggested method is suitable
for modestly equipped laboratories.

Summary: The influence of trimethylolpropane as comonomer for
polyester fibre polymer on the change of properties has ben investigated.
It was founded that a small addition of this substance will reduce the
tendency to pilling, at the same time increasing dyestuff affinity, but
total oligomers content grows.

Summary: The quantity of catalysts in polyester, which are added
during the process of the polymer synthesis, has a decesive influence on
some essential properties of polymers and fibers. Therefore, regular
industrial control of this parameter is needed. The paper deals with
possibilities of quantitative determination by means of spectrometric
procedures, neutronic activation analysis and polarography.

Summary: The orientation of the supermolecular structure of the
polyester fibres was investigated by measuring the optical unnisotropy. The
investigations were carried out with the polarisation microscopeby using
two methods: compensation method for determining birefrigance and
Jamin-Lebedef-s interferenc method for determining refractive index in the
direction of the main and side fibre axis. The factors of orientation and
the average angles of inclination of the supermolecular structure
asquantitative indications were calculated.

Summary: Poly(ethylene terephtalate) in the form of granules and,
after processing in the form of filaments, has been fractionated according
to molecular mass by the column dissolution method in phenol/n-heptane as a
solvent/nonsolvent system. Stepwise solventand temperature gradients were
used. The molecular mass distribution were dtermined and the distribution
functions were approximated by the theoretical Tung-s two parameter
function.

Summary: The effects of repeated washing, dry cleaning, short-term
thermal treatments as well as short-term succesive stresses on the
deformation resistance of elastomeric yarns through the forces at the
elastic limit and through the forces from the plastic area were
investigated. Covered elastomeric yarns and bare elastomeric filaments were
examined. The results obtained show a considerable influence of the crimp
characteristics of the texturized yarns in cover as well as certain
differences in the behaviour of yarns with elastodiene and elasthane core.
