The nonwoven fibrous loop material of the invention contains an open fibrous loop layer comprised predominately of polypropylene polymer, copolymer or blend fibers. The nonwoven fibrous loop layer material is autogeneously bonded to a backing layer formed of polypropylene polymers or copolymers having a percent isotacticity of less than 70%, optionally with additional layers present provided so that the overall nonwoven fibrous loop material is a laminate having a circular bend stiffness of less than about 9 Newton and having tensile strength of at least 1500 g/2.54 cm-width.

Abstract: A multilayer hollow fiber body useful, for example, in a blood oxygenator. The multilayer hollow fiber body comprises a single hollow fiber mat arranged in the form of a body comprising a plurality of hollow fiber plies. The mat comprises a plurality of generally parallel hollow fibers disposed at regular intervals, and a plurality of connecting fibers holding the connecting fibers. The mat is repeatedly folded over on itself along fold lines, each of which is at an oblique angle to the hollow fibers, to form a multilayer hollow fiber body in which the hollow fibers of any ply of the multilayer hollow fiber body are disposed so as to cross the hollow fibers of an adjacent successive ply of the multilayer hollow fiber body. Also disclosed is a method of making the multilayer hollow fiber body.

Abstract: A diaper construction is provided with an external porous reinforcement strip at the front part of the outside of the diaper, which strip provides reinforcement against an adhesive fastening tab and provides an oil-contamination tolerant adhesion surface.

Abstract: An anisotropic elastic web, particularly an anisotropic elastic film layer having a machine direction and a cross direction and having a thickness of from 20 to 300 microns formed of an extruded blend of a block copolymer elastomer portion and a polyolefin polymer portion blended in a ratio of from 10:1 to 0.4:1, respectively. The elastomer portion generally is a block copolymer elastomer formed of A blocks and B blocks, the A blocks are formed predominately of monoalkenyl arene and the B blocks are formed predominately of conjugated diene. The polyolefin portion is comprised predominately of an inelastic fiber forming polyolefin polymer, copolymer or blend. The anisotropic film layer has a F10 force Ratio (MD to CD) of at least 1.5. This anisotropic elastic web is usable in a variety of garment applications where an elastic is supplied in roll form and requires strength in a machine direction and elastic properties in a cross direction.

Abstract: A method of forming apertures generally greater than about 0.05 square millimeters in a thin sheet material. The thin sheet material includes a first side and a second side at least one side of the thin sheet material is substantially coated with an adhesive. The method comprises the steps of (a) placing the adhesive-coated thin sheet material on a patterned anvil having a pattern of raised areas wherein the height of the raised areas is equal to or less than the thickness of the thin sheet material and the adhesive; and (b) subjecting the thin sheet material to a sufficient amount of sonic vibrations to aperture the thin sheet material and the adhesive; and whereby the thin sheet material and the adhesive is apertured in a pattern generally the same as the pattern of raised areas on the patterned anvil.

Abstract: A reinforced viral resistant seam for an article of protective apparel constructed by arranging first and second thermoplastic webs and at least one reinforcing strip thermally bondable with the webs along a common seam edge. An ultrasonic welding wheel having a cutting edge immediately adjacent to the welding surface is used to form a viral resistant, comfortable, high tensile strength seam suitable for articles of protective apparel.

The coating composition utilizes an inorganic metal oxide in combination with particular anionic surfactants. The coating compositions are particularly useful in the manufacture of disposable surgical masks and face shields.

Abstract: A modular blood treatment system with a blood treatment cartridge having a blood treatment media receiving opening defining an entrance of a first chamber. The first chamber defines a first interior space and a second interior space. At least one cardiotomy blood sucker port is in fluid communication with the first interior space via a cardiotomy manifold. The cardiotomy manifold preferably defines a downward curving surface from the at least one cardiotomy blood sucker port to the first interior space having a radius of about 2.54 to 7.62 cm. A venous blood inlet is in fluid communication with a second interior space within the interior space. A first blood treatment media is interposed between the first interior space and the second interior space. A second blood treatment media is interposed between the second interior space and the blood treatment media receiving opening. A blood storage section has an outlet port extends substantially across the blood treatment media receiving opening.
