A three-dimensionally structured fiber fabric has a high fluid absorption capacity of at least 5 g fluid per g of fiber fabric and elevations and depressions that occur alternately and regularly with reference to the fabric plane, which includes at least one nonwoven fabric layer and a shrunk fabric bonded to it. The bond between the nonwoven fabric layer and the shrunk fabric has been produced by hot bonding, and the hot bonding occurred at least perpendicular to the direction of the greatest shrinkage of the shrunk fabric, in the form of regularly arranged lines. Furthermore, spaces have formed between the nonwoven fabric layer and the shrunk fabric, at the alternately occurring elevations and depressions, which spaces promote the fluid absorption capacity of the fabric. These fabrics may be used as wiping cloths, wet wipes, as fluid dispensers for cleaning or for applying fluids, etc.

Nonwoven fabrics with high fluid absorption capacity and a regular structure, process for their production, and their use

A laminate is claimed, having a first cover layer, a fabric with perforations as the middle layer, and a second cover layer, as are a method for its production and the use of the laminate as a fluid absorption and distribution layer made of a nonwoven fabric layer oriented in the Z direction, for absorbent hygiene articles. A three-dimensional form is achieved in that the fabric is present in the shrunk state in the middle layer, i.e. is brought into this state.

Laminated material and method for its production

A three-dimensionally structured fibrous web made up of continuous-filament layers which alternate perpendicular to the surface plane, and denser short-fiber layers that are permanently thermally bonded in a continuous or spot-like manner to the filament layers, the wide-mesh continuous-filament layers representing a scrim, lattice, or netting, has on the short-fiber layers repeating, fold- or wave-shaped elevations. In the manufacturing process, all of the layers of the laminate are subjected together to a shrinkage process at a temperature which lies between the softening and melting points of the scrim material.

Flat nonwoven fiber aggregate with three-dimensional structure and method for its production

A hook and loop fastener for flat structures, particularly for textile products, having a hook part and an interlocking part, the interlocking part being made of a nonwoven composite having worked-in, textured, polymeric threads, the nonwoven composite being used as support for the textured threads, and the textured threads forming the loops for the hooks.

A medical bandaging material made of a microfilament nonwoven fabric with a mass per unit area of 30 to 150 g/m and a tear strength of >40 N/5 cm, the nonwoven fabric being made of continuous multicomponent filaments, melt-spun, stretched, and directly laid down to form a nonwoven fabric, having a titer of 1.5 to 5 dtex, and the continuous multicomponent filaments, after optional prebonding, being split, at least to the extent of 80%, into continuous microfilaments having a titer of 0.01 to 1.0 dtex and bonded.

Medical bandaging material

A composite material, including a laminate ( ) made of a film ( ) bonded to a nonwoven ( ), wherein the nonwoven ( ) and the film ( ) are only bonded together at discrete points and the laminate ( ) is stretched in at least one direction after being formed.

Composite material

Bodies containing superabsorber polymers, having superabsorber polymers bonded together with polymer fibers, wherein at least part of the superabsorber polymers are present as a microporous open-celled foam. The bodies are used for producing diapers, sanitary napkins, tampons and other articles of personal hygiene.

An insole for shoes is a three-dimensionally shaped laminate composed of two adhesive-free formed fabrics, the formed fabric on the foot side being thin and abrasion-resistant, and the thicker formed fabric forming the base material of the insole consisting of staple fibers, having a composition of 50-60% by weight of core/sheath-polyester/copolyester fibers with a melting range of the core component of 255.degree.-260.degree. C. and of the sheath component of 110.degree.-140.degree. C., 5-15% by weight of high-shrinkage polyester fibers, and 25-40% by weight of absorbent fibers. The base material has a mass per unit area of 800-1200 g/m.sup.2 with a thickness of 0.70-0.85 cm. The insole is produced by shrinking the loosely needled base material by means of superheated water vapor, subsequently laminating the base material to an emboss-bonded and heated formed fabric by means of an adhesive compound, deep drawing of the laminate which was first heated above the melting range of the sheath component of the base material fibers inside an unheated molding press, and subsequently punching out the individual deep-drawn molded insoles.

Inner sole for shoes and process for its manufacture

The invention refers to a lining material for shoes, comprising two to three layers of nonwoven fabric which are spot (heat) bonded together, wherein a wear resistant ply facing towards the foot (inside of the shoe) is comprised of synthetic fibers and that ply is adhered on its the side facing away from the foot to a moisture absorbent ply which contains about 30 to 70 wt. % cellulosic fibers.

A microporous, polymeric film is prepared by dissolving methylene-chloride-soluble, film-forming polymers completely in methylene chloride. Then an aqueous phase is prepared containing non-methylene-chloride-soluble, water-soluble thickeners and, if desired, additives, and brought to a viscosity of about 0.07 to 0.5 Pa s. The aqueous phase is then dispersed in the polymer solution and the resultant paste is spread onto a support material or intermediate support, the methylene chloride is evaporated, the resultant membrane is transferred to the actual support, and finally the water is removed by drying.

Disclosed is a process for producing a surgical sponge which contains contrast agent embedded in a polymer matrix in proportions of up to 70 wt. %. The matrix consists of a polymer material free of plasticizers. In the process for the production of the sponge a matrix for the contrast agent is used, which is an uncrosslinked, viscous liquid, prepolymer state until after it has been extruded onto the basic fleece material, and not until a process step that then follows is the polymerization completed.

Disclosed is a nonwoven, textile sponge for use in medical and hygienic applications consisting of at least one outer, thermally consolidated, moisture-repellent fiber layer containing at least 80% synthetic heterofil filaments and at least one layer of absorbent fibers. The sponge is perforated, but does not have any substantial fiber entanglement, and contains no binding agent of any kind. Also disclosed is a method for the manufacture of the sponge, in which the fiber nonwovens are laid one on the other, hydraulically perforated without fiber entanglement, and then thermally consolidated through heterofil filaments.

The filler fleece material of the invention consists of a laminate of two layers of fleece containing bonding fibers. The thinner layer, which serves as a covering fleece, consists to at least 60% of thermoplastic bonding fibers which melt at the same or a lower temperature than those of the central fleece. This combination makes it possible, after the depositing of the fiber layers and the thermal consolidation of the central fleece, to perform a process for smoothing the cover layer, in which the laminate is exposed in a roller gap to a temperature that is above the fiber melting point of the cover fleece. The filler fleece material of the invention, on account of its smooth yet still sufficiently air-permeable cover layer, is no longer subject to fiber protrusion. Furthermore, the clinging of projecting fibers during application to textile surface materials is reliably prevented.

A microporous, multilayer material has a layer of microfibers having a weight of from about 0.5 to about 60 g/m.sup.2, the microfibers having diameters of from about 0.1 to about 10 microns. The microfiber layer is covered on opposite sides with nonwoven layers and all the layers are bonded together with a pattern of water repellent and, preferably, elastic paste members sufficiently penetrating through the layers. A process for making the microporous, multilayer material imprints the paste for the penetration-bonding paste members on one or both sides of the layers only squeezed dry after washing and water-repellentizing baths.
