  • Publication number: 20020065384
    Abstract: Elastic fibers and fabrics made from homogeneously branched substantially linear ethylene polymers are disclosed which can be produced on conventional polypropylene or polyethylene fiber or fabric processes. They can be used to produce highly elastic structures that can have recycle compatibility between elastic and non-plastic components. The novel fibers have at least about 50% recovery at 100% strain. The fibers and fabrics are especially useful in making fabricated articles and components thereof (e.g., disposable diapers).

  • Publication number: 20020049269
    Abstract: The present invention relates to a method of making improved polyolefinic elastic articles from cured, irradiated or crosslinked amorphous ethylene interpolymers. In particular, the invention relates to a method of making a shaped article (e.g. film or fiber) characterized by improved elevated temperature elasticity as well as washability and dryability. The inventive elastic article comprises a substantially cured, irradiated, or crosslinked (or curable, irradiated or crosslinkable) homogeneously branched ethylene interpolymer characterized as having a density less than 0.90 g/cm3 and containing at least one nitrogen-containing stabilizer. The improved elastic article of the present invention is particularly suitable for use in applications where good elasticity must be maintained at elevated temperatures and after laundering such as, for example, elastic waist bands of undergarments and other clothing.

  • Publication number: 20020019490
    Abstract: The subject invention is directed to fibers and polymer blend compositions having improved bonding performance. In particular, the subject invention pertains to a multiconstituent fiber comprising a blend of a polypropylene polymer and a high molecular weight (i.e. low melt index or melt flow) ethylene polymer. The subject invention further pertains to the use of the fiber and polymer blend composition which has improved bonding performance in various end-use applications, especially woven and nonwoven fabrics such as, for example, disposable incontinence garments and diapers. The fibers have good spinnability and provide fabrics having improved bond strength and elongation.

  • Patent number: 6176952
    Abstract: The present invention relates to a method of making a breathable nonwoven fabric having enhanced moisture barrier properties. In particular, the invention pertains to a method of making a meltblown fibrous layer having an improved hydrohead performance (e.g. greater than 40 millibars (16 inches of H2O) and adjacent to at least one spunbond fibrous layer, wherein the method comprises secondary processing of the meltblown layer prior to bonding to spunbond layers. The resultant spunbond/meltblown (SM) nowoven fabric is breathable and characterized as having a cloth-like feel and softness and enhanced hydrohead performance rendering it suitable for use in, for example, personal hygiene, disposable industrial garment and infection control/clean room applications for items such as coverings, incontinence pads and diapers, especially as a diaper backsheet or containment flap.

  • Patent number: 4965135
    Abstract: A multilayer film is provided in the form of an extruded sheet for food wrapping and cooking procedures. The film is made up of alternating layers of a first generally ductile material and a second generally brittle material. Upon wrapping a food item or container, the film exhibits dead fold and/or twistability characteristics. In one embodiment, the materials of the film are chosen to have softening points above about 450 degrees F. so that the film can be used in conventional ovens.
