ORLON
Orlon is obtained by polymerizing acrylonitrile. It is represented
as [CH2 CH (CH)]n, It is a white fibre; sticks at 235°;
ironing temperatures above 160°C may cause yellowing; sp. gr. is 1.17. Its
inflammability is similar to that of rayon and cotton. Generally it has very
good resistance to mineral acids; excellent resistance to common solvents,
oils, greases, neutral salts, sunlight but it is degraded by strong alkalis. It
resists attack by moulds, mildew and insects. The 100% polyacrylonitrile fibres
are rarely used commercially due to difficulty in dyeing.
Orlon fibre is suitable for furnishing (awnings, tents and furniture),
anode bags in electroplating, knitwear, rugs, and dressings.
