The invention relates to a textile fabric having a coating composed of two layers of thermoplastic hot-seal adhesives of differing compositions applied one on top of the other, the second hot-seal adhesive, which is applied to the first, having a melting point of &#x3e;135&#xb0; C. and a melt flow index (MFI) value of 50 to 250 g/10 minutes (190&#xb0; C./2.16 kg). The invention further relates to a method for producing a textile fabric, comprising the following steps: a) producing a textile fabric using a textile fabric manufacturing technique; b) applying a layer of a first hot-seal adhesive to the textile fabric; and c) applying a layer of a second hot-seal adhesive to the textile fabric so as to d) form a layer of the second hot-seal adhesive over the layer of first hot-seal adhesive, the second hot-seal adhesive used having a melting point of &#x3e;135&#xb0; C. and a melt flow index (MFI) value of 50 to 250 g/10 minutes (190&#xb0; C./2.16 kg). The textile fabrics may be used as interlining or lining material which can withstand stress during care treatment.

Textile fabric with improved finish, production and use thereof

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.

Hook and loop fastener for flat materials

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

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.

Bodies containing superabsorber polymers, methods of producing such bodies, and the use of such bodies

A flame penetration blocker for fuselages which is a laminate of a 100 to 600 g/m.sup.2 mica paper having laminated on one or both sides of it 30 to 300 g/m.sup.2 needled fabric layers made of flame-retardant fibers. The adhesive effect of the laminate is produced by a partially cross-linked, latently adhesive, temperature resistant binding agent incorporated into the mica paper itself. The laminate is made by adhesive bonding one or both surfaces of a mica paper of the named type with a needled fabric layer under pressure and at a temperature that does not trigger the final cross-linking of the binding agent.

Flame penetration blocker for fuselages

An interior equipment part for vehicles, in particular a support part for automobile roof linings, of single-layer or three-layer construction, such that the layer(s) exposed to the action of heat consist of 25-100% by weight of polybutylene terephthalate fibers and of at most 75% by weight of higher melting polyester fibers.

Interior equipment part for vehicles

In a process for manufacturing an interior fitted part for motor vehicles, such as an inside roof lining for automobiles, a staple-fiber formed fabric of a drawn polyethylene terephthalate matrix component and of a binding component is subjected at least once during the process to an annealing process, which increases the thermal stability of the fitted part. Also disclosed is a fitted part manufactured by this method.

Method for manufacturing interior fitted part for motor vehicle

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.

Method for preparing a microporous film

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.

Process of making a surgical sponge containing an x-ray contrast agent

Disclosed is a composite adhesive web and a process for the production of such a web. The thermally adhesive web of the invention is comprised of a composite of randomly arranged thermoplastic filaments or, parallel thermoplastic filaments interconnected by randomly arranged thermoplastic fibers or filaments, and a fibrous thermal adhesive nonwoven sheet containing thermoplastic fibers, preferably low melting thermally adhesive fibers.

Composite adhesive webs and their production

The invention disclosed herein relates to a method for bonding the opposing surfaces of textile materials to each other with a heat-seal adhesive. The heat-seal adhesive is a polyurethane urea heat-seal adhesive prepared by first preparing a chain-extended polyurethane from at least one diisocyanate, at least one polydiol, and chain-extenders. The chain-extenders may comprise a mixture of low molecular weight diols comprised of at least one low molecular weight diol having a molecular weight below about 500 and having side chains or ether groups, and at least one unbranched low molecular weight diol having a molecular weight below about 500. The chain-extended polyurethane has a free-isocyanate group content which comprises from about 10 to about 40 mole percent of the isocyanate content of the starting mixture. An emulsifier is added to the chain-extended polyurethane, and the polyurethane and emulsifier mixture is emulsified with water. Diamines or diamine mixtures may be added to the emulsion.
