Fiber Entangling And Interlocking Patents (Class 28/103)
  • Patent number: 4148676
    Abstract: Non-woven articles, including garments and porous sheet materials, are made from continuous filaments by ejecting continuous yarn or filaments into turbulent air and contacting them with binder in a high density fog while still suspended in air, so that the binder dries sufficiently to become non-migrating before the yarn is deposited on the screen or mold on which the fibers are brought into contact with each other and bonding takes place. This method is particularly suitable for making garments of elastomeric fibers, not easily handled in ordinary production machinery. Another generally applicable advantage is that the resultant products are exceptionally flexible and that the articles produced do not split into stratified binder-rich and-poor areas, but are uniformly bonded throughout.

  • Patent number: 4144370
    Abstract: A double layer, nonapertured textile fabric comprising two integrally entangled layers. The first layer contains fibers arranged to form a pattern of apertures or openings in the layer. The second layer comprises a plurality of entangled areas which are disposed within the apertures of the first layer to form a unitary textile fabric.

  • Patent number: 4127637
    Abstract: This invention relates to a unique method of fabricating a dry-formed, adhesively bonded nonwoven sheet and to the sheet formed thereby. The method of this invention includes the steps of forming a low integrity, dry-formed fibrous web having a basis weight in the range of from about 30 grams per square meter to about 170 grams per square meter; embossing the web to provide spaced-apart densified regions and high loft regions with the densified regions covering from about 15% to about 40% of the planar area of the web and having a density greater than about 0.150 grams per cubic centimeter, and with the high loft regions having a density of less than about 0.

  • Patent number: 4106166
    Abstract: This invention is directed to a method for expanding the width of preformed fibrous webs. Fibrous webs having fibers oriented in their lengthwise direction can be widened by this method and this orientation is still maintained in the widened web. The method involves feeding the web to a blade edge lying at an angle to the lengthwise direction, abruptly changing the direction of travel of the web at the edge from the lengthwise direction to a second direction, and turning the web fibers in the second direction while expanding the width of the web. The profile of fibrous webs, i.e., the thickness, uniformity, weight and fiber density, across its width can also be changed and controlled according to the method disclosed.

  • Patent number: 4095312
    Abstract: Method and apparatus for making a nonwoven fabric wherein a first group of filaments are projected in a longitudinal direction into the nip of a pair of nipped and moving collecting surfaces in such a manner that the filaments fold into and are captured and held by the nip with spans of the filaments lying in the plane of the nip and at the same time projecting a second group of filaments in a longitudinal direction toward one of the collecting surfaces at a location spaced from the nip. The second group of filaments impinges on an impact plate positioned above the collecting surface and is pulled off the impact plate by the moving collecting surface, this causing the filaments in the second group to extend primarily in the machine direction. The moving collecting surfaces carry the groups of filaments into contact with each other to form a nonwoven fabric which is subsequently bonded in a conventional manner to form a finished fabric.

  • Patent number: 4086687
    Abstract: Apparatus for loosening the needled structure of a textile fabric. A moveable surface having penetrating elements which penetrate the fabric, produce planar forces on the internal fibers of the fabric. A co-operating surface provides an opposite force to that exerted by the moveable surface. The moveable surface moves at a different speed than the cooperating surface and compressive forces are applied to the internal fibers of the fabric at discrete points by the penetrating elements, and internal fibers are moved relative to other fibers.

  • Patent number: 4064605
    Abstract: A method for continuously producing a non-woven web having uniform distribution of filaments from natural or synthetic fibers comprising drafting with use of a high speed air-jet type drafting device a number of filaments which are fed from a filament source and blasting the drafted filaments onto a face of a moving collector, which is characterized in that the distribution of the filaments is controlled by passing the filaments through a filament distribution-controlling device comprising a filament guide passage having a narrow rectangular cross section and an air sucking means provided at least an one rectangular side wall of the filament guide passage, said controlling of the distribution of the filaments being performed with the air stream sucked spontaneously or positively from the air sucking means.
