Disclosed is a flame barrier made of a nonwoven fabric of partially graphitized polyacrylonitrile fibers having a weight per unit area of 40 to 100 g/m.sup.2 and a maximum thhickness of 1.8 mm. The nonwoven fabric is bonded with highly energetic water jets. The flame barrier can be used as a component of a planar multi-layer structure.

Flame barrier made of nonwoven fabric

A textile laminate consists of a nonwoven padding material of low specific volume and of a filament-reinforced nonwoven, the laminate having a total thickness of more than 2 mm. The nonwoven padding material has a raw density of less than 0.025 g/cm.sup.3 and a thickness of 1.6 to 60 mm. The filament-reinforced nonwoven is composed to 10 to 60 g/m.sup.2 of a fleece with a raw density greater than 0.35 g/cm.sup.3 and of 3 to 10 g/m.sup.2 reinforcing filament and is laminated onto the nonwoven padding material.

Nonwoven laminate

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.

An iron-on interlining composite of nonwoven and knit material is described, the knit being similar to the nonwoven material as to fiber structure and the knit fibers being tightly welded to the nonwoven fibers.

Iron-on interlining composite of knit layer and nonwoven layer of

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.

Filler fleece material and method of manufacturing same

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

Fused and needled nonwoven interlining fabric

Disclosed herein is a fixation insert having improved resistance to back-riveting (flash-through) and a method for the manufacture thereof, consisting of a planar textile structure of natural and/or synthetic threads and a coating, applied to the front side, of a thermally softenable adhesive compound, where the planar structure has at least on the back side a layer of fibers which extend beyond the surface of the planar structure predominantly perpendicularly, and where the fibers are elastically resilient. The fibers are elastically connected to the threads and are deposited thereon in an electrostatic field.

Fixation insert with improved flash-through safety and method for

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.

Method for the manufacture of a fluffy, light-weight, soft nonwoven

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.

Spot bonded pattern for non-woven fabrics

Described herein is a nonwoven fabric with improved hot-press properties and a method for manufacturing the same, consisting of natural and/or synthetic fibers which are united to form an open thread structure and are coated entirely or partially with a coating of an elastic bonding agent, where the ends of short fibers protruding beyond the surface of the nonwoven fabric in nap-fashion on one or both sides are bound into the coating. The short fibers are introduced into the thread structure in an electrostatic field and may be distributed regularly or irregularly.

Non-woven fabric with improved hot-press properties and method for

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.

Soft, drapable, nonwoven interlining fabric

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 0.9 mm, and the areas of the embossed and printed patterns are arranged in straight lines parallel and at right angles to the longitudinal direction, and the areas within the lines of the embossed pattern and within the lines of the printed pattern are evenly spaced. The underside of the fabric may carry an adhesive by means of which it may be bonded to the underside of an outer fabric as a lining therefor.

Nonwoven fabric having the appearance of a woven fabric

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.
