Abstract:
A carpet having a pile layer, a support layer and a rear coating. The carpet has an intermediate layer formed from a mat comprising fibrous parts made predominantly of plastic which are in part thermoplastic and of low-melting point fibers and in part higher-melting point fibers, and melted regions providing coherence of both of the fibers, the melted regions being formed of partly melted regions of the low-melt-ing point thermoplastic fibers.
Abstract:
A method of producing a nonwoven mat from recycled carpet. The carpet comprises high and low melting thermoplastic fibers. The method comprises shredding the carpet into pieces, scattering the pieces onto a support web to form a layer and heating at least the surface thereof to affect melting of the lower melting thermoplastic fibers.
Abstract:
A camouflage material, preferably in the form of a camouflage mat, for use as protection against radar observation, comprises a support layer (1) with filament or threadlike pieces, which affect radar waves, for example carbon or metal thread. With a view to optimal protection against radar observation, these substances are applied to the support layer (1) with arbitrarily mutual directions and positions and with random spatial orientations and distribution.
Abstract:
Die Erfindung betrifft zunächst ein Belagelement (1), insbesondere Teppichfliese mit einer ersten, eine Sichtseite bildenden Lage (2) und einer zweiten Verbindungslage (3), wobei die Verbindungslage (3) zur möglichst rückstandsfrei wieder entfernbaren Aufbringung des Belagelements (1) auf einem Untergrund (6) ausgebildet ist. Zur gebrauchsvorteilhaften Weiterbildung, wird vorgeschlagen, dass die Verbindungslage (3) durch einen Schaumstoff gebildet ist, wozu die Einstellung des Schaums so vorgenommen ist, dass sich oberflächlich eine zerklüftete Struktur ergibt, wodurch sich bei Aufdrücken auf den Untergrund (6) ein Anhafteffekt ergibt. In einer weiteren Lösung wird diesbezüglich vorgeschlagen, dass die Verbindungslage (3) durch geschäumten Latex gebildet ist, wozu die Einstellung des Latexschaums so vorgenommen ist, dass bei einem Aufdrücken des Belagelementes (1) auf einen Untergrund (6) zumindest in der äußersten Schicht der Verbindungslage (3) befindliche Membrane der Schaumstoffporen (5) zum Platzen gebracht werden und wobei sich bei einer Aufhebung des Anpressdruckes (P) zufolge elastischer Rückstellung der Schaumstoffschicht ein Ansaug-Unterdruckeffekt in den so aufgeplatzten Poren (5) ergibt.
Abstract:
A fabric is formed of yarns having soiling-hiding and soilingprone characteristics which are visually distinct one from the other in the surface of the fabric once the fabric has been soiled. The soiling-prone yarns comprise yarns formed of multi-lobal fibers or filaments where the soiling particles collect in the cavities of the lobed surfaces. Preferably, the soilinghiding yarns are formed of hollowfil synthetic fibers or filaments. By embedding one or more yarns of the soiling-prone type in the fabric, e.g., carpet, the yarns become differentially visually distinctive relative to one another upon soiling of the fabric.
Abstract:
Bitumen-polymer membrane (10), of the type comprising a support (11) immersed in a mixture of bitumen, polymeric resins and fillers (12), and surrounded by such mixture (12), characterized in that the support (11) comprises a perforated metallic support the holes or openings of which are adapted to be passed through by the mixture (12) in the semifluid state, and is such as to retain the mixture (12) during cooling and consolidation during a process for producing the bitumen-polymer membrane, the mixture (12) being clung to the support (11) by way of the holes or openings.
Abstract:
A fabric (10) is formed of yarns having soiling-hiding (18) and soilingprone (18) characteristics which are visually distinct one from the other in the surface of the fabric (10) once the fabric (10) has been soiled. The soiling-prone yarns (18) comprise yarns formed of multi-lobal fibers or filaments (22) where the soiling particles collect in the cavities of the lobed surfaces. Preferably, the soilinghiding yarns (18) are formed of hollowfil synthetic fibers or filaments (24). By embedding one or more yarns of the soiling-prone type (18) in the fabric (10), e.g., carpet, the yarns (18) become differentially visually distinctive relative to one another upon soiling of the fabric.
Abstract:
A composite elastic layer, which has improved resistance to shear force and functions both as a cushioning material and as a sound proof material, is comprised of a loop pile tufted fabric, which is made from a backing fabric and a plurality of loop piles. An elastomer composition is applied to the pile stratum of the loop pile tufted fabric. The elastomer composition infiltrates into voids between fibers of the loop pile, and forms a solid skin on the fibers of the loop pile. The composite elastic layer reinforces the elastic property of the loop pile, and on the other hand, the fiber of the loop pile also reinforces the tensile strength, especially the resistance to tearing, of the solid skin.
Abstract:
METHOD OF BACK-COATING PILE CARPET CONTAINING PILE YARNS BOUND BY EMBEDMENT IN A RELATIVELY IMPREVIOUS POLYMER LAYER COMPRISING THE STEPS OF PERFORATING THE IMPERVIOUS LAYER TO PERMIT PASSAGE OF GASES THERETHROUGH, AND APPLYING A HEAT BONDABLE POLYMERIC BACK-COATING TO THE PERFORATED CARPET.
Abstract:
A PILE FABRIC COMPRISING: (A) A BACKING MATERIAL AND, (B) PILE LOOPS ANCHORED IN SAID BACKING MATERIAL, SAID PILE LOOPS COMPRISING: (1) A FLAMMABLE FIBER AND, (2) A METALLIC LAMINATE THREAD COMPRISING: (A) A SELF-SUPPORTING METAL PLY AND, (B) A POLYMERIC PLY BONDED TO THE METAL PLY.
THESE PILE FABRICS ARE SELF-EXTINGUISHING AND STATIC CHARGE RESISTANT.
