  • Patent number: 6782589
    Abstract: A method for creating a nonwoven laminate fabric has steps of depositing a first nonwovne layer on a moving support, depositing a second nonwoven layer over the first layer, and conveying the layers under a manifold. The manifold has a plurality of jet clusters separated from one another by a distance. Water is directed form the jet clusters onto the underlying layers to thereby create a laminated fabric. Because the jet clusters are separated from one another, the laminate fabric is “pattern entangled”. Bundling occurs along substantially linear lines, with much lighter bundling in regions between the linear bundling regions. The result is a fabric with regions of relative strong entanglement and other regions of much lighter entanglement. When three layers are laminated, with top and bottom layers of thin veneer and a center layer of pulp the method of the invention has been discovered to result in a laminate fabric with particular utility as a flushable wipe product.

  • Patent number: 6751830
    Abstract: An apparatus and method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices and impinging on the fabric. The pressurized liquid exits in a coherent or columnar fashion from elongated orifices that are generally rectangular or linear in shape. The elongated orifices can be arranged so as to produce various effects on a web of fabric, including striping, graduated shading and seer-suckering. The elongated orifices also facilitate the hydroenhancement of high-warp-count fabrics without streak or moire effects. Liquid filtration can be relaxed without clogging the orifices, because the elongated orifices permit larger solid objects to pass. The use of elongated orifices also enhances the energy efficiency of the hydroenhancement process.

  • Patent number: 6735834
    Abstract: Colored patterning of a web-shaped nonwoven or a composite made of a nonwoven and a fabric or knit is achieved by water jet needling. The nonwoven provided as the upper layer of two layers is provided with one or more colors or is colored or printed itself and is placed on a second nonwoven or a woven or one that has a different color. Then both layers are subjected to the water jets that displace the fibers, with the colored fibers in the first layer being displaced into the second layer to produce a pattern on the underside of the second layer. It is also possible, instead of colored fibers in the nonwoven of the upper layer, to move them when they are not colored into a second layer that can have any color.

  • Patent number: 6557223
    Abstract: Improvements in Hydroenhancement efficiency are obtained by operating a manifold in relative movement to fabric transported under the manifold so as to deliver a low energy to the fabric per pass in multiple passes on the fabric. This results in greater enhancement efficiency and reduction in wasted energy, and also improves fabric coverage and reduces fabric shrinkage. The low-energy per pass, multiple-pass approach can be implemented with improved hydroenhancing equipment of reduced equipment size and cost which simulate multiple passes on the fabric. Embodiments employ a manifold or manifold system that is reciprocated, oscillated, or rotated to simulate multiple passes on the fabric. Other variations for improving hydroenhancement include angling the manifold at a diagonal to the fabric travel direction, using a high density number of double rows of jets to eliminate interference patterns.

  • Patent number: 6546605
    Abstract: A fabric having at least one hydraulically napped surface comprised of tangled fibers is disclosed. Because the fiber tangles are created from intact, undamaged fibers, fabric strength is not adversely affected by treatment. In addition, laundering enhances entanglement and the aesthetic qualities attributed to this fabric property: surface texture (hand), resistance to pilling, drapeability, and the like. These subjective characteristics have been quantified using values from the Kawabata Evaluation System. A process for creating such fabrics has also been disclosed. The fabric passes through one or two treatment zones in which high pressure fluids (e.g., water) are directed at the fabric surface as the fabric moves away from a support member. In the case of dual treatment zones, a substantially lower pressure is used in the second treatment zone.

  • Patent number: 6502288
    Abstract: A method of forming durable nonwoven fabrics by hydroentanglement includes providing a precursor web comprising a fibrous matrix of staple length fibers and/or substantially continuous filaments. The precursor web is subjected to hydroentanglement on a three-dimensional image transfer device to create a patterned and imaged fabric. Enhanced imaging is achieved by advancing the precursor web onto the movable imaging surface of the image transfer device at a rate substantially equal to the rate at which the image surface moves relative to one or more associated hydroentangling manifolds. Treatment with a polymeric binder composition enhances the integrity of the fabric, permitting it to exhibit desired physical characteristics, including strength, durability, softness, and drapeability. Mechanical compaction of the imaged and patterned fabric, such as by sanforizing, enhances the desired physical properties.

In the preferred embodiment, the finishing station includes a substantially excess-free applicator which helps to prevent thick spots in the coated fabric web which may occur when a coating applicator is stopped and restarted. In the preferred embodiment, the finishing station includes a curing station downstream from the applicator. The curing station may include both a drying station and a heat set station downstream from the drying station. The operating temperatures of the drying and heat set stations are controlled to minimize the amount of air having VOCs to be treated before being discharged into the atmosphere.

  • Publication number: 20020050037
    Abstract: The present invention is directed to a method of imaging a woven textile fabric by positioning the fabric on a three-dimensional image transfer device, and subjecting the fabric to treatment with high pressure liquid streams. A regular pattern defined by the image transfer device is thereby durably imparted to the fabric. The use of a three-dimensional image transfer device facilitates efficient commercially viable use of the method, while avoiding the creation of repeating defects which can occur when imaging fabrics on wire mesh screens.

  • Patent number: 6343410
    Abstract: Improvements in hydroenhancement efficiency are obtained by operating a manifold in relative movement to fabric transported under the manifold so as to deliver a low energy to the fabric per pass in multiple passes on the fabric. This results in greater enhancement efficiency and reduction in wasted energy, and also improves fabric coverage and reduces fabric shrinkage. The low-energy-per-pass, multiple-pass approach can be implemented with improved hydroenhancing equipment of reduced equipment size and cost which simulate multiple passes on the fabric. In one embodiment, a jigging hydroenhancing equipment transports the fabric back and forth under a stationary manifold between a pair of unwind/windup reels to simulate multiple passes on the fabric. Other embodiments employ a manifold or manifold system that is reciprocated, oscillated, or rotated to simulate multiple passes on the fabric. Other variations for improving hydroenhancement are disclosed.

  • Publication number: 20010023521
    Abstract: Improvements in hydroenhancement efficiency are obtained by operating a manifold in relative movement to fabric transported under the manifold so as to deliver a low energy to the fabric per pass in multiple passes on the fabric. For example, a low energy per pass of {fraction (1/10)} to {fraction (1/48)} the total energy delivered in 10 passes or more can obtain good enhancement results as compared to conventional hydroenhancing at higher total energy levels delivered in fewer passes. This results in greater enhancement efficiency and reduction in wasted energy, and also improves fabric coverage and reduces fabric shrinkage. The low-energy-per-pass, multiple-pass approach can be implemented with improved hydroenhancing equipment of reduced equipment size and cost which simulate multiple passes on the fabric. In one embodiment, a jigging hydroenhancing equipment transports the fabric back and forth under a stationary manifold between a pair of unwind/windup reels to simulate multiple passes on the fabric.

  • Patent number: 6253429
    Abstract: A method and system for improving the appearance, covering ability and physical properties of woven fabrics by supporting the fabric which is to be treated on a foraminous surface, directing a plurality of columnar liquid streams in the form of oblique vanes against the fabric at an angle which is oblique to the warp direction of the cloth. The columnar streams impinge the cloth under pressure which is sufficient to penetrate and effect an enter-entangling of the fibers in the fabric, and the fabric which is thus treated is advanced under similar streams to treat substantially the entire surface of the fabric. The direction of the jets impinges on opposite sides of the fabric and they are oriented in a position which places them in direct opposition of one another.

  • Patent number: 6055710
    Abstract: The permeable drum for needling tissues, nonwovens, or other permeable materials of a certain width consists of a normally perforated sheet metal drum on which strips that are thin and extend axially over the length of the drum are arranged with small distances between them around the drum. The strips radially support a very thin sheet metal jacket with microfine perforations and produce a uniform flow of liquid through the material that rests externally against the sheet metal jacket. The strips can be joined together for example to form a honeycomb profile and thus uniformly transfer the hydrodynamic load developed during needling to the screen drum.
