Abstract:
An adhesive sheet material comprising a dimensionally stabilized and water-resistant fibrous carrier, the back of which carries a continuous impermeable film adhering intimately to the carrier yet preserving its suppleness and conferring on it resistance to stretching and preventing it from fraying, a layer of dry adhesive on this film which is compatible therewith and adherent thereto to protect its suppleness against aging, insensitive to moisture, heat and cold, and adapted to be activated by a liquid medium prior to use.
Abstract:
The invention relates to the use of mixtures that contain an aqueous dispersion of a vinyl acetate polymer and an aqueous dispersion of a vinyl acetate-ethylene copolymer for carpet coating compositions, and corresponding carpet coating compositions, as well as carpets which are coated with such carpet coating compositions.
Abstract:
The carpet backing materials comprise a woven, non-woven or knitted thermoplastic backing fabric, preferably at least partially incorporating polyolefin, in particular polypropylene, yarns, to which a fleece is adhered by means of a hot melt powder adhesive having a softening point below that of the thermoplastic backing fabric. The fleece may, if desired, be pretreated to form a self-supporting web prior to being adhered to the backing fabric. A process for the preparation of the carpet backing materials and tufted carpets incorporating the backing materials are described and exemplified. When incorporated into tufted carpets, the backing fabrics avoid the problem of grinning, and improve tuft locking and dimensional stability of the finished carpets.
