Abstract:
The invention provides a yarn suitable for use in making a cleanable dirt control textile, comprising at least two sets of fibres which have been twisted together, the first set comprising fibres of 32 to 100 decitex, the second set comprising fibres of 110 to 290 decitex, wherein finished yarn is of 6000 - 9800 decitex. Preferably, the yarn contains a total of from 3 to 8 fibres.
Abstract:
A tufted carpet or mat product comprises a primary support fabric having an underside and an upper side, a layer of rubber or synthetic rubber adhered e.g. by vulcanization to the underside of the primary support fabric, and yarn nops extending through the primary support fabric for forming of a nap on the upper side of the primary support fabric and for forming of nap nop bottom parts between the rubber layer and the primary support fabric. In said tufted product the nap comprises 70-95, preferably 80 weight per cent animal wool and 5-30, preferably 20 weight per cent synthetic fibers, such as fibers of acryl, fluorocarbons, polyacetales, polyamides, polyesters, polyethylenes, polypropylenes, polyurethanes and similar fibers being relatively fire inhibiting, the primary support fabric material consists of fibers which per se has a high ignition point, and the rubber layer has been selected from the group of washable rubbers not being fire supporting and which preferably also are resistant against oils, gasoline, acids and bases. Thereby a tufted product is achieved which has a hitherto unknown self-extinguishing or fire inhibiting effect and which is washable after use and dirt and water binding during use.
Abstract:
A method of manufacturing a nap mat having a rubber backing with nap free rubber edge zones. The nap layer is fastened into a woven or non-woven primary texture, which along with the nap layer is fastened to the upper side of an unvulcanized rubber backing by a press vulcanizing operation, whereby the unvulcanized rubber is pressed by means of a press diaphragm and is heat vulcanized when the underside of the rubber backing is lying abutting against a moulding plate. Before the press vulcanizing operation rubber strips are placed against the underside of the rubber backing and below the encircling edge of the nap layer, and during the press vulcanizing operation the strips are joint vulcanized with the rubber backing, so that they are caused to form integrated parts thereof. Thereby it is possible to make the rubber backing all over thinner than it has been possible before, without the nap free rubber backing side edges becoming inclined to separate from the mat during frequent washing operations and consequently the mat having a lower weight is easier to carry and handle.
Abstract:
A dust control mat (5) with pile and a caoutchouc or plastic backing (6) comprises a layer (1) of pile and a non woven primary bottom thereof being fixed to the backing material (6). A flexible reinforcing layer (3) is embedded in the backing (6), which reinforcing layer consists of fibres selected from non woven materials and spun-bonded materials, the fibres of which have been heat fixed and crosslinked, and whereby at least a part of at least one of the side edges of the reinforcing layer (3) has been exposed on the surface of the backing (3) within the piled area.
