Patent number: 4610352Abstract: Nonwoven fabrics are described comprising a layered fabric having an inner layer of substantially thermoplastic material, for example Nylon 6 fibers, disposed adjacent and recessed bonded to at least one outer layer or a pair of outer layers of textile length fibers by means of heat and pressure. The thermoplastic fibers in the inner layer have a lower melting point than the outer fibers in the fabric. A nonwoven fabric constructed in this manner has qualities of; low levels of debris, high compressibility, low abrasiveness, and dimensional stability. These qualities are decidedly of use in many products, most particularly as a liner in computer diskettes, wherein a liner material must be used to wipe the magnetic disk within the computer diskette to keep it free of foreign particles, which may cause errors in the transfer of information onto or from the magnetic disk.Type: GrantFiled: May 6, 1985Date of Patent: September 9, 1986Assignee: The Kendall CompanyInventors: Jon A. Howey, Randall J. Rogers

Patent number: 4606338Abstract: A bandage comprising a fabric formed from at least one layer of nonwoven hydroentangled fibers having a skim coat of adhesive disposed thereon. Subsequent to entangling the fibers, the fabric is compacted to arrange the fabric into a series of wave-like configurations having crests and valleys. These wave-like configurations allow the fabric to stretch when pulled, and recover to most of its original form when the tension is released. After compacting, a light coat of adhesive is applied to the crests of the fabric to impart some slip resistance to the surface of the fabric while leaving the valleys substantially free from adhesive. The adhesive may be applied to one side or both sides of the fabric, depending on the requirements of the fabric. The thusly formed bandage, when stretched for application, has discontinuous areas of adhesives disposed therein that provide sufficient slip resistance while also permitting complete repositionability.Type: GrantFiled: May 6, 1985Date of Patent: August 19, 1986Assignee: The Kendall CompanyInventors: J. Michael Greenway, Peter J. Schoots, Donald Patience

Patent number: 4586606Abstract: Nonwoven fabrics are described comprising a layered fabric having an inner layer of substantially thermoplastic material, for example fibers, disposed adjacent and thermally bonded to at least one outer layer or a pair of outer layers of textile length fibers by means of heat and pressure. The thermoplastic fibers in the inner layer have a lower melting point than any other fibers in the fabric. A nonwoven fabric constructed in this manner has qualities of; low levels of debris, high compressibility, low abrasiveness, and dimensional stability. These qualities are decidedly of use in many products, most particularly in computer diskettes, wherein a material must be used to wipe the magnetic disk within the computer diskette to keep it free of foreign particles, which may cause errors in the transfer of information onto or from the magnetic disk.Type: GrantFiled: October 28, 1983Date of Patent: May 6, 1986Assignee: The Kendall CompanyInventor: Jon A.

Patent number: 4531386Abstract: An improved fabric for covering dampener rolls comprising a ground yarn, a water shrinkable inlay yarn and a hydrophilic pile yarn. The fabric is fashioned into a cylindrical tube and is securely fastened to a roll by thoroughly wetting the tubular fabric and roll in water until the water shrinkable inlay yarn shrinks causing the fabric to tighten down on the roll. When the inlay yarn of the dampener cover shrinks it does so in a widthwise or circumferential manner, thereby exerting a force upon the surface of the dampener roll similar to the force exerted by a series of rubber bands, thus securing the dampener cover to the dampener roll. This unique fabric construction also allows for a reduction in lengths of fabric needed to cover a roll, because the fabric shrinks circumferentially and not lengthwise. Thus, a cover may be measured more precisely to the length needed to cover a specific roll.Type: GrantFiled: June 1, 1983Date of Patent: July 30, 1985Assignee: The Kendall CompanyInventors: William T. England, Wing Y. T. Lau

Patent number: 4499139Abstract: An aerated latex microsized single ply hydroentangled fabric wherein a latex mixture is aerated by an Oakes foamer, and then applied to a fabric by a knife-over-roll applicator whereby the latex is worked below the surface of said fabric. The thusly sized fabric is then dried by passing it through an oven. The present invention enables the acquisition of sufficient hydrophobicity in the fabric so as to be a bacterial barrier while preserving therein comfort, drapeability, air permeability, flexibility, and hand. In addition to preserving the above properties, microsizing does not detract from sterilizability of the fabric.Type: GrantFiled: March 2, 1984Date of Patent: February 12, 1985Assignee: The Kendall CompanyInventor: Walter E. Schortmann

Patent number: 4211227Abstract: A nonwoven hospital sponge material has been provided comprising a layered fabric having an inner core of a substantially hydrophilic material disposed adjacent at least one outer or surface layer or between a pair of outer layers of a substantially hydrophobic material, said sponge material being bonded by passing the material through rolls engraved in a pattern of lands and grooves in such a way that a repeating pattern of three degrees of compression are imposed therein: high compression, intermediate compression and, little or no compression. A nonwoven fabric bonded in this manner becomes more absorbent, loftier, has good surface integrity and does not adhere to the wound surface, when the nonwoven sponge material is then compacted subsequent to the bonding step. This thusly constructed, rather lighweight nonwoven material, produces a relatively inexpensive and disposable hospital sponge and dressing material having all of the desirable features of the more expensive woven materials commonly used today.Type: GrantFiled: July 3, 1978Date of Patent: July 8, 1980Assignee: The Kendall CompanyInventors: Gary C. Anderson, Jon A. Howey, Harish A. Patel

Patent number: 4186463Abstract: A nonwoven fabric having alternating stripes of high fiber density and low fiber density is made in such a manner that substantially all of the fibers in the stripes of high fiber density are oriented in substantially one direction, for example the machine direction, while substantially all of the fibers in the adjacent stripes of low fiber density are oriented in a direction substantially normal to that direction. This phenomenon can be produced by passing a fluid-borne stream of discretely separated fibers over a set of finger-like striping bars that are disposed, equidistantly from each other, directly over a moving conveyor screen or by a set of impervious resist areas in the shape of bars, or the like, disposed directly on the moving screen.Type: GrantFiled: December 22, 1975Date of Patent: February 5, 1980Assignee: The Kendall CompanyInventor: Preston F.

Patent number: 4183995Abstract: An unlayered nonwoven fabric has a uniformly repeating pattern of high fiber density areas, each surrounded by low fiber density areas. The low fiber density areas inconnecting the high fiber density areas are composed of substantially parallelized strands of fibers entering into the high fiber density areas from at least eight directions. These octadirectionally oriented nonwoven fabrics have advantageous tear characteristics, and by the nature of the uniform cover factor of the web, they have many desirable and advantageous uses.Type: GrantFiled: September 21, 1978Date of Patent: January 15, 1980Assignee: The Kendall CompanyInventor: Preston F. Marshall

Patent number: 4115911Abstract: A top-drive filling spindle for use in the manufacture of textile yarn is provided wherein the tapered tip thereof is of a through hardened steel material that would more readily resist wear caused by the driving action of the quill disposed thereon. A top-drive filling spindle having wear on the tapered tip thereof can advantageously be retipped by grinding the worn tip to a predetermined size; applying a sleeve of through hardened steel or the like thereover; securing the sleeve thereon; and, finally grinding the thusly secured sleeve to the standard taper for top-drive filling spindles. With the application of the through hardened sleeve, it is anticipated that spindle wear would not occur for perhaps six to twelve years or more -- a two to three fold increase over the life of spindles currently used by those skilled in the art.Type: GrantFiled: January 10, 1977Date of Patent: September 26, 1978Assignee: The Kendall CompanyInventors: Ernest G. Poole, Lucius M. Hair

Patent number: 4083913Abstract: Air-laid fibrous webs are formed from randomly-oriented mixed fibers containing a minor proportion of short, flock-length, thermoplastic and thermoretractile fibers. The air-laid web is then heated, without pressure, to cause melting of the thermoplastic fibers to the point of substantially complete loss of fiber identity. The relative orientation of the web thus formed is stabilized so that the fibers therein maintain their general positional relationships through subsequent stresses incurred during the operations of printing, saturating, drying, winding into roll form and the like.Type: GrantFiled: December 17, 1973Date of Patent: April 11, 1978Assignee: The Kendall CompanyInventor: Preston F.
