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.
