Abstract: The present invention discloses a method and apparatus for reinforcing non-woven sheets by printing a cross-linkable binder on one surface by means of a relief or photogravure printing cylinder while simultaneously printing the opposite surface at corresponding positions with a thermally softenable adhesive applied by means of a screen printing cylinder.

Abstract: A method is disclosed wherein a nonwoven fabric is synchronously coated with an adhesive composition and impregnated with a radiation cross-linkable binding agent under conditions that render the composition tacky and adherent but not penetrating and that cross-link the agent to at least in part bind the fibers of the fabric.

Abstract: A process of producing a pliable roller uses a flexible strip of material with a tension element longitudinally therealong, the tension element having a lesser longitudinal extensibility than the flexible strip of material. The tension element and the flexible strip of material are fixed together and portions of the flexible strip of material are longitudinally folded together along the tension element. At least after the fixing, the flexible strip of material with the tension element longitudinally therealong is wound, longitudinally, about a roller core in such manner as to form contiguous windings thereabout projecting outwardly from the roller core.

Abstract: A soft, fluffy, bulky, nonwoven fabric is disclosed which is made from bonded or at least partially fused fibers which have been needle-punctured.

Abstract: A method is disclosed wherein a nonwoven fabric composed at least in part of thermally fusible fibers is at least partially fused and then is punched by needles to produce a soft, fluffy fabric that resists mechanical wear.

Abstract: This application relates to a non-woven fabric wherein the fibers of the fabric are bonded to each other and/or to another material in a plurality of equally spaced-apart spots, wherein the spots are the same size and are combined in a plurality of identical groups of not less than three nor more than five identical spots, each of said groups of spots being spaced apart from each other, and each of said spots within each group being positioned along a curved or straight line wherein the steady extension of said line beyond the end-spots of said group positioned along said line intersects and adjacent line along which an adjacent group of spots is positioned, and wherein the ratio of the distance separating the spots within each group of spots to the distance from an end-spot in each group to the next adjacent line along which an adjacent group of spots is positioned, is about 0.5 to about 3.0.

Abstract: The present invention provides a method for manufacturing a fabric-type artificial leather, wherein a nonwoven fabric is formed by using a dry method to join together hydrophobic fibers. The fabric so formed is densified by needling and the activation of shrinking forces. It is then impregnated with a mixture of a heat sensitive elastomeric bonding agent, powdered barium sulfate and a compound that reacts with acid to form a gas. The impregnated fabric is then exposed to a heated, acidified liquid which triggers coagulation of the bonding agent and liberates a gas formed by reaction of the acid and acid-reactive compound. The resulting solidified fabric is then washed, dried and ground-over on at least one side to produce a nap. Finally, the fabric is intensively fulled.

Abstract: A multilayered nonwoven fabric is described which exhibits excellent resistance to drycleaning and washing abrasion but nevertheless is soft and drapable. It contains a varying amount of thermal bonding fibers in the various layers.

Abstract: A cleaning cloth for household and industrial use comprising a soft resilient needled nonwoven fabric having a plurality of rubber strips surmounting its top surface in the manner of relief, the height of the rubber strips being about 0.2 to 0.4 times their width but not more than about 0.5 times the thickness of the nonwoven fabric, the nonwoven fabric on its underside carrying a continuous layer of an open-pore latex foam which projects above the bottom surface and penetrates into the nonwoven to the extent of about 10 to 40 percent of the thickness of the nonwoven fabric.

Abstract: A method for improving the heat retention of a planar textile structure by coating at least one surface of the structure with a dispersion of liquid carrier, cross-linkable binder and metallic powder, and then cross-linking the binder and removing the liquid carrier from the coating.

Abstract: A method for bonding an unbonded fibrous web of natural and/or synthetic fibers by means of a binder which is cured by exposure to UV light, wherein the fibrous web is first compressed, smoothed, and heated, then one or both surfaces of the web is printed with a pattern of a prepolymer binder having a viscosity of from about 500 to 5000 centipoise and the prepolymer binder is cured by exposing the printed fibrous web to ultraviolet light.

Abstract: A nonwoven fabric having the appearance of a woven fabric and suited for use as a lining material for garments, comprising a nonwoven fabric substrate embossed on its face in a regular pattern of discrete areas of a maximum diameter of about 0.45 mm spaced not more than about 1.0 mm apart and carrying thereon in a regular printed pattern discrete areas of bonding-agent of a maximum diameter of about 0.45 mm spaced not more than about 0.7 mm apart. Advantageously the bonding-agent contains a coloring additive which differentiates it from the color of the nonwoven fabric, the spacing of the areas of the bonding-agent printed pattern is from about 50 to 95% of the spacing of the areas of the embossed pattern, the areas of the embossed and printed patterns are rectangular, the lengths of their lateral edges corresponding to a ratio of about 2:3, the sum of the length and width not exceeding a value of about 0.

Abstract: A fibrous nonwoven fabric of good drapability, comprising geometrically arranged spaced first surface areas of about 0.02 to 0.2 mm.sup.2 in area in which its fibers are chemically or thermally bonded at their intersections, and second area whose junctions are at least partially reopened and in which the bond points are disposed closely adjacent one another is produced by bonding a non-woven fleece chemically or thermally, and then stretching the resulting fabric at spaced areas so as to expand it partially and form areas where the fibers are less or not bonded. Where a chemical binder is used it may be set only partially prior to stretching, setting being completed thereafter.

Abstract: A nonwoven interlining and nonwoven chest piece are combined and together employed to be incorporated into a garment such as jacket or coat by pressing. This is accomplished by providing thermally activatable adhesive on both faces of the combination so that steam pressing serves to join it to the garment fabric. The individual nonwoven layers are only partially prefixed or internally bonded and a further mass of resilient binder adds to the cohesiveness of the unit.

Abstract: A scouring and cleaning cloth having a coating of a solid binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars, the bars in at least one surface having embedded therein at least one of an abrasive and a soap additive.

Abstract: An absorbent textile sheet material suitable for use as a cleaning cloth, skid-resistant underlayment or the like, comprising a consolidated nonwoven fabric coated on up to about 70% of both surfaces with binding agent present as a three-dimensionally superelevated printed pattern providing a squeegee-like action when wiped over a wet surface, is produced by impregnating a fibrous web with a binding agent and drying to form a coherent sheet material, applying to each surface of said sheet material a foamed dispersion comprising rubber, the foam being printed onto each surface to cover from about 30 to 70% of the surface, and heating to coagulate the foam and to leave on each surface a superelevated printed pattern of binder exerting a squeegee-like action in use. Advantageously the fibrous web weighs about 60 to 300 g/m.sup.
