Estimating the term…
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.
A carpeting material comprising a backing fabric and fibres standing up from the backing fabric as pile or tufts, wherein the pile or tuft fibres comprise 75 to 98 percent by weight of conventional carpet yarns and 2 to 25 percent by weight of stiff fibres of filaments which are not plied with the conventional carpet fibre yarns and which are arranged to act as dirt scrapers, said carpet yarns being formed from fibres selected from the group consisting of nylon, acrylic, regenerated cellulose, wool, polyester, cotton and polypropylene fibres of less than 30 decitex per filament, and the stiff fibres or filaments being more resistant to being trodden down than the conventional carpet yarns.
In a process for preparing carpeting material in which conventional pile or tuft carpet yarns formed of fibres selected from the group consisting of nylon, acrylic, regenerated cellulose, wool, polyester, cotton and polypropylene fibres of less than 30 decitex per filament are fed to carpet forming machinery selected from the group consisting of tufting machines and carpet looms to form rows of pile or or tufts, the improvement comprising the step of feeding stiff fibres or at least one stiff filament to the carpet forming machinery together with a conventional pile or tuft carpet yarn so that the pile or tuft fibres of the carpeting material produced comprise 75 to 98 percent by weight of the fibres of said conventional carpet yarns and 2 to 25 percent by weight of the said stiff fibres or filaments, said stiff fibres or filaments being more resistant to being trodden down than said conventional carpet yarn so as to be capable of acting as dirt scrapers.
