    Description / Table of Contents: Die physikalischen Eigenschaften von mit Methylmethacrylat und Methylacrylat in Stickstoffatmosphäre bei 60 °C unter Verwendung von Cerionen als Initiator gepfropftem Nylon-6-Garn wurden mit den Eigenschaften des Ausgangsgarns verglichen. Mit zunehmendem Pfropfungsgrad wurde eine höhere Dichte, geringeres Feuchtigkeitshaltevermögen und geringere Doppelbrechung festgestellt. Die mechanischen Eigenschaften wurden beträchtlich herabgesetzt. Bei den dynamischen Eigenschaften ergab sich eine höhere mechanische Dämpfung und vermindertes elastisches Verhalten. Die Anfärbbarkeit war ebenfalls herabgesetzt.
    Notes: The physical properties of nylon 6 yarn grafted with methylmethacrylate and methylacrylate in nitrogen atmosphere using ceric ion as initiator at a temperature of 60 °C have been compared with those of ether extracted and initiator treated parent yarn. With an increase in graft-on percentage an increase in density, decrease in moisture regain and birefringence was observed. The mechanical properties were impaired considerably. The dynamic mechanical properties results indicated increase in mechanical damping and reduction in elastic behaviour as a consequence of graft copolymerization. The dye uptake was also found to be decreased in these grafted samples.

    Description / Table of Contents: Das thermische Verhalten von natürlicher Wolle und mit Methylacrylat, Äthylacrylat, n-Butylacrylat und Methylmethacrylat gepfropften Wollproben wurde mittels Thermogravimetrie an Luft bis zu 575°C bei einer Aufheizgeschwindigkeit yon 6°C pro Minute untersucht. Die thermische Beständigkeit war bei mit Methylacrylat und Äthylacrylat gepfropfter Wolle mit kleinem Pfropfungsgrad höher als bei natürlicher Wolle, aber bei höherem Pfropfungsgrad nahm sie ab. Bei mit Butylacrylat und Methylmethacrylat gepfropften Proben veränderte sich die thermische Stabilität gegenüber der von natürlicher Wolle kaum.
    Notes: Thermal behaviour of natural wool and wool grafted with methylacrylate, ethylacrylate, n-butylacrylate, and methylmethacrylate was studied using dynamic thermogravimetry in air up to a temperature of 575°C at a heating rate of 6°C per minute. The thermal stabilities of the samples grafted to various percentages of graft-on were compared from their initial decomposition temperature (IDT), their integral procedural decomposition temperature (IPDT), and their activation energy values for decomposition. The thermal stability was found to be better in methyl- and ethylacrylate grafted wool with low graft-on as compared to that of natural wool; but at higher graft-on thermal stability decreased. In butylacrylate and methylmethacrylate grafted samples, thermal stability did not change significantly as compared to that of natural wool.

    Description / Table of Contents: Durch Röntgenbeugung wurden Wollproben untersucht, die mit Methylacrylat, äthylacrylat, n-Butylacrylat und Methylmethacrylat gepfropft worden waren. Die Hauptreflexionen der Wolle blieben unbeeinflußt. Das Verhältnis der Höhe beider Intensitätspeaks wuchs mit dem Gehalt an Pfropfpolymeren und zeigte eine Zunahme des Ordnungsgrades an. Die mittlere Kristallitgröße stieg auch mit der Pfropfung an und ergab bei den gepfropften Fasern ein engeres Spektrum an Ordnung.
    Notes: X-ray diffraction of wool graft-copolymerized with methylacrylate, ethylacrylate, n-butylacrylate and methylmethacrylate monomers was studied taking equatorial scans using an x-ray diffractometer. The prominent reflection arcs of wool remained unaffected by grafting as was evident from the x-ray photographs. The ratio of the two intensity peak heights increased with the percentage graft-on indicating an increase in the degree of order. The average crystallite size also increased with grafting showing a narrower spectrum of order in the case of grafted fibres.

    Description / Table of Contents: Das thermische Verhalten von natürlicher Wolle und chemisch modifizierten Wollfasern (oxidiert, reduziert, methyliert und vernetzt) sowie daraus gewonnener Pfropfpolymerer mit MMA wurden mittels dynamischer Thermogravimetrie in Luft und mittels Differentialthermoanalyse in Stickstoff untersucht. Die relative thermische Stabilität hängt von der chemischen Modifizierung ab; oxidierte Wolle erwies sich als thermisch stabiler als natürliche. Pfropfung reduzierte die Gesamtthermostabilität der Fasern.
    Notes: The thermal behaviour of natural wool and chemically modified wool fibres (oxidized, reduced, methylated and crosslinked) and their graft-copolymers with methyl methacrylate were investigated by dynamic thermogravimetry in air and differential thermal analysis in nitrogen atmosphere. The relative thermal stability depended on the chemical modification and oxidized wool was found to be thermally more stable than natural wool. Grafting reduced the overall thermal stability of the fibres.

    Description / Table of Contents: Das thermische Verhalten von Nylon 6 (20 Denier Monofilamente) und der Pfropfcopolymeren von Nylon 6 mit Acrylamid und Acrylnitril wurde durch dynamische Thermogravimetrie untersucht. Die thermischen Stabilitäten der gepfropften Proben wurden aus ihren Primärthermogrammen durch Berechung der Anfangszersetzungstemperatur (IDT), integralen Zersetzungstemperatur (IPDT) und Aktivierungsenergie (E) ermittelt. Die thermische Stabilität der mit Acrylnitril gepfropften Proben steigt mit höherem Pfropfungsgrad an, während die mit Acrylamid gepfropften Proben mit steigendem Pfropfungsgrad instabiler werden.
    Notes: The thermal behaviour of nylon 6, 20 denier, monofilament (semi-dull) and the graft copolymers of nylon 6 with acrylamide and acrylonitrile was studied using dynamic thermogravimetry in air at a heating rate of 6°C/min. up to a temperature of 550°C. The thermal stabilities of the samples grafted with acrylamide and acrylonitrile to various percentages of grafting were computed from their primary thermograms by calculating the values of initial decomposition temperature (IDT), integral procedure decomposition temperature (IPDT) and activation energy (E). The results show that the thermal stability of the samples grafted with acrylonitrile increases with increase in graft-on percentage and the thermal stability of the samples grafted with acrylamide decreases with increase in graft-on percentage. The reduction is, however, not very significant.
