Improvements in the art of making pile fabrics by needle looming a non-woven fabric. The conventional needle loom is modified to use needles in which the conventional barbed end is replaced with a knife edge end so that a filament or fiber pushed out of the non-woven fabric by the needle is cut as the needle reaches its maximum throw between the needle knife edge and an anvil means placed below the tufting plate. The anvil means provides a surface against which to cut the filaments or fibers whi...

An iron-in stiffening insert comprising a support carrying a multiplicity of dots of adhesive arranged thereon in a random pattern. This arrangement prevents a furrowed appearance or a moire effect. The dots are generally circular and the spacing between adjacent dots ranges from about 1 to 2.5 times the average diameter of the dots with the spacing between adjacent dots being within 20% of the average adjacent dot spacing.

An apparatus for use with a device for producing a suitable electric field to effect the electrodynamic spraying of solutions, dispersions, or mixtures of solids. The apparatus includes at least one spray station for spraying into a given spray zone. Each spray station includes two spaced apart tanks for holding the medium to be sprayed and which are disposed on both sides of the spray zone. An endless band is supported by pulleys disposed at each tank for circulating the band and constantly run...

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 ...

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 colo...

A hydrophilic foam is produced by mixing an isocyanate terminated branched polyethylene polyol with a polyester prepolymer and water. The foam may be used to impregnate fabrics, e.g., non-wovens, to produce reinforced sheets of foam of high absorbency and markedly improved abrasion resistance. Preferred polyesters are condensation products of adipic acid plus one or more alkanediols or a polylactone. Other prepolymers may also be included in the mix undergoing foaming, along with conventional ad...
