Nomenclature
Polyacrylonitrile; Fiber A. Description and references
Obtained by polymerizing acrylonitrile. Review
of prepn, properties, and uses: R. W. Moncrieff, Man-Made Fibres (John Wiley, New York, 1963) pp 446-467.
Properties
White fiber. Sticks at 235°. Ironing temps above
160° may cause yellowing. Sp gr 1.17. Flammability similar to that
of rayon and cotton. Generally has very good resistance to mineral
acids; excellent resistance to common solvents, oils, greases, neutral
salts, sunlight; fairly good resistance to weak alkalies but is degraded
by strong alkalies. Resists attack by molds, mildew, insects. 100%
polyacrylonitrile fibers rarely used commercially due to difficulty
in dyeing.Use
Fiber suitable for outdoor furnishings (awnings,
tents, outdoor furniture), indoor furnishings, anode bags in electroplating,
knitwear, rugs.
