New Developments in Acrylic Carpet Fibres for Specific End–uses

Abstract

There is considerable activity in the introduction of new acrylic fibres, and second–and third–generation fibres are being developed for specific end–uses. Bicomponent fibres have found considerable application in woven carpets because their increased bulk and cover offer advantages over traditionally used fibres. Improved flame–resistant fibres incorporating halogen compounds have been developed to meet flammability requirements for carpets. Modacrylic blends are used for shag and some ‘saxony’ (high–pile low–density) applications. Three acrylic fibres of different dyeability have been developed for continuous piece dyeing: reduced–affinity basic, regular or deep basic, and acidic. Rapid–dyeing fibres are being introduced for use on the Craw ford–Mohasco equipment with which the fixation time is limited to 3 min at 100°C Finally, highshrinkage fibres can be used to impart extra bulk and cover or alternatively to produce sculptured effects in woven or tufted carpets.
