Abstract: An absorbent facing is disclosed which has significant one-way valve characteristics for aqueous fluids. The facing is produced by a process which comprises the steps of: (a) superimposing a thin polymer film and a first web comprising absorbent fibers, to form a second web; (b) heating the second web to a temperature such that the polymer film is in a formable state; (c) while the said second web is so heated, simultaneously applying shearing and compressive forces to the second web to form said polymer film into a coating on said first web, the coating comprising a fine pattern of continuous areas which lie between and interconnect discontinuous areas, wherein the polymer in the continuous areas comprises a continuous or substantially continuous coating on the surface of said first web, and wherein most of the polymer in the discontinuous areas is coated on individual fibers; and (d) cooling the coated web thus formed to cool the polymer below its forming temperature.

Abstract: A strong, durable nonwoven fabric comprising polyester and/or polyolefin fibers arranged in a pattern of high density, lightly entangled fiber regions. Distributed throughout the fibers is an adhesive binder material to provide the final fabric with improved strength characteristics.Entangled nonwoven fabrics are dry print bonded to produce nonwoven fabrics having an excellent combination of strength, softness and durability.

Abstract: A high bulk, heat shrunk fabric of texturized thermoplastic yarns in an open pattern of lock stitch knitted or leno woven yarns, said fabric exhibiting good biaxial stretch and recovery.

Abstract: A water impervious laminated material is described. A preferred embodiment comprises a three-layer plastic film sandwiched between and fuse bonded to two layers of conjugate fibers having a low melting sheath and a high melting core. The inner layer of the plastic film is relatively high melting while the two outer plies of the film are low melting. The sheaths of the conjugate fibers have been fuse bonded to the plastic film at a temperature below the melt temperature of the cores of the conjugate fibers so that the cores retain their initial fiber-like integrity.

Abstract: An apparatus, method and fabric formed thereby for heat or fusion bonding a web comprising conjugate fibers.

Abstract: An apertured non-woven fabric comprising a web of thermoplastic fibers is described. The fabric is formed with a multiplicity of fused patterned regions and adjacent substantially non-fused regions, there being apertures formed within a plurality of the fused patterned regions but not within the adjacent regions. The fabric is produced by heat embossing a non-woven web of thermoplastic fibers at a temperature above the softening point of the fibers whereby the regions of the web compressed by the projections of the embossing means become fused, and immediately thereafter drafting the embossed web so that apertures are formed in the fused patterned regions.

Abstract: An extensible water impervious laminated material having an improved hydrostatic head at higher extension is described. A preferred embodiment comprises an inner creped hydrophobic microfine fiber structure sandwiched between and bonded to two reinforcing layers of nonwoven fibers, said microfine fiber structure comprising at least one ply of microfine fibers having a fiber diameter of up to 10 microns. This material is especially useful as an operating room gown.

Abstract: There is disclosed a fabric made up of short conjugate fusible fibers and longer, base fibers. The conjugate fibers have an exposed low melting point component having a lower melting point than the remainder of said fibers and said base fibers. In the method of the present invention, a web of short conjugate fibers and longer base fibers is passed through an entangling mechanism where the short fusible fibers are concentrated and intertwined in heavily entangled knot areas. The entangled web is heated to thermobond at least the low melting point component of the conjugate fibers to each other and preferably to the surrounding base fibers to reinforce and strengthen the fabric.

Abstract: An absorbent pad of non-woven fabric having high absorbency and integrity has on one side a layer of binder material for providing a surface having an absorbency reduced with respect to the remainder of the pad, the remainder of the pad being free of binder.

Abstract: An extensible elastic composite with elastic recovery and process for making the same comprising intermittently securing an elastic member to a substrate which prior to initial stretching is easily less extensible than said elastic member.

Abstract: A water impervious laminated material is described. A preferred embodiment comprises a three-layer plastic film sandwiched between and fuse bonded to two layers of conjugate fibers having a low melting sheath and a high melting core. The inner layer of the plastic film is relatively high melting while the two outer plies of the film are low melting. The sheaths of the conjugate fibers have been fuse bonded to the plastic film at a temperature below the melt temperature of the cores of the conjugate fibers so that the cores retain their initial fiber-like integrity.

Abstract: A fabric of which at least 10% by weight comprises polyester fibers, which fabric is durably soil releasing on laundering and which is useful for preparing the facing sheets of mattress pads. This fabric is finished with a soil release finish consisting essentially of a cured mixture of a fluorochemical soil release agent, an adhesive binder and a cross-linking agent.

Abstract: A water impervious laminated material is described.

Abstract: A sterile low cost disposable fabric suitable for use in making repellant breathable drapes and gowns for use in a sterile environment, said fabric comprising rudimentary discontinuous and alternating rows of entangled cellulosic and polymeric fiber rows extending in the machine direction, and having a predominantly poylmeric surface and predominantly cellulosic surface and at least said cellulosic fibers being subject to a repellant treatment, yielding a breathable repellant soft fabric with enhanced drape and enhanced frictional properties.

Abstract: A method and apparatus is disclosed for producing high quality fibrous webs at high rates of speed. Fibers are fed to a rotating lickerin for opening, then to a rotating card cylinder for individualizing, and are then doffed into an air stream from which the fibers are condensed, as on a moving foraminous belt.
