B. Morgenstern et al., CELLULOSE-BASED POLYMER BLEND FILAMENTS SPUN FROM N-METHYLMORPHOLINE-N-OXIDE, Die Angewandte makromolekulare Chemie, 243, 1996, pp. 129-142
The influence of a small addition (<15 wt.-%) of an aromatic polyamide
[poly(2,6-dichloro-1,4-phenylene terephthalamide) (P26ClPTA)] as addi
tive on the textile-physical properties of cellulose filaments was inv
estigated. The blend filaments were spun from homogeneous blend soluti
ons prepared in the common solvent N-methylmorpholine-N-oxide. Most of
the estimated properties of blend filaments containing not more than
10 wt.-% of P26ClPTA do not differ significantly from those of pure ce
llulose filaments. However, the wet abrasion resistance attains a maxi
mum at a P26ClPTA content of 10 wt.-%. At higher P26ClPTA content the
fibrillation tendency of the blend filaments is increased. Coincidenta
lly, a decrease of tenacity and wet abrasion resistance was obtained.
