ABSTRACT:
In a carpeting material of the kind comprising a backing fabric and fibres standing up from the backing fabric as pile or tufts, the pile or tuft fibres comprise 75 to 98 per cent by weight of conventional carpet fibres and 2 to 25 per cent by weight of stiff fibres or filaments arranged to act as dirt scrapers. The conventional carpet fibres are nylon, acrylic, regenerated cellulose, wool, polyester, cotton or polypropylene fibres, or a mixture of two or more of these, of less than 30 decitex per filament. The stiff fibres or filaments may be heavy monofilaments, for example of nylon, polyester or unplasticized polypropylene of from 30 to 300 tex, or they may be of metallic material. Alternatively, the stiff fibres can be in the form of twisted yarn which has been resinated to stiffen it.
Processes for making the carpeting material are also described and claimed.
