Nonwoven Fabric Has An Elastic Quality Patents (Class 442/328)
  • Patent number: 9724248
    Abstract: A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from a multi-layered, elastic film laminated to a nonwoven web facing. Latent elasticity is imparted to the composite through the use of at least one base layer that contains a thermoplastic elastomer and at least one skin layer that contains a propylene/?-olefin copolymer. During formation, the film is stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the propylene/?-olefin copolymer. The stretched elastic film may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated at or above the softening point of the copolymer) to soften the crystalline domains and allow the chains to return to their unoriented state.

  • Patent number: 9597855
    Abstract: A composite stretch material which is composed of a first nonwoven fabric sheet part and a second nonwoven fabric sheet part and elastic members disposed therebetween. In each nonwoven fabric sheet part, concave parts and convex parts are formed in the thickness direction. The concave and convex parts formed alternately repeatedly in a first direction define convex-concave rows. The convex-concave rows are separated from each other by non-shaped regions which contain neither concave parts nor convex parts and which extend along the first direction. The non-shaped regions are joined to each other with the elastic member therebetween. The convex parts of the first nonwoven fabric sheet part enter respectively into the concave parts of the second nonwoven fabric sheet part, while the convex parts of the second nonwoven fabric sheet enter respectively into the concave parts of the first nonwoven fabric sheet part.

  • Publication number: 20150044928
    Abstract: A non-woven fabric (1) that is modified with activated carbon is needled on an elastic or inelastic textile sheet material (2), preferably a woven fabric or a knitted fabric. With this method, it is achieved that the strength of the textile sheet material (2) can be imparted to a non-woven fabric (1) that is otherwise not tear-resistant, whereby the adsorption properties of the activated carbon that are necessary in protective textiles are completely retained. During needling, the elastic or inelastic textile sheet material (2) is stretched or kept stretched, and stress is relieved after needling. The effect that is thus achieved is that the non-woven fabric (1) does not tear when the textile good or the molded part is stretched again, since the non-woven fabric then is stretched out from a compressed initial state.

    Abstract: The invention relates to unique applications for the novel high melt flow, low viscosity, selectively hydrogenated styrene-butadiene-styrene (hSBS) or selectively hydrogenated controlled distribution styrene-butadiene/styrene-styrene (hSBSS) block copolymers, wherein the melt flow rate of said block copolymer is at least 100 g/10 min at 230° C. under 2.16 kg mass according to ASTM D1238. These block copolymers are novel and have the highest melt flow rate of any styrenic block copolymer also possessing high strength and elasticity. It has applications that prior to the present invention were not normally possible due to the normal low melt flow rate of styrenic block copolymers. The present invention also encompasses various fields of use such as a fiberglass hSBS or hSBSS reinforced mat, low viscosity hSBS or hSBSS coatings for industrial uses, hot melt adhesives prepared from hSBS or hSBSS blended with polyalpha-olefins, and elastic film, fiber, and nonwoven constructions using hSBS or hSBSS.

  • Patent number: 8415263
    Abstract: A composite material as a sheet material is described, being relatively cheap, most useful as a raw material of a sanitary product or the like, such as underwear, dust-proof mask or dispensable paper diaper, etc., and good in processability, stretchability, gas-permeability, softness, and touch. The composite material is formed by laminating a stretchable layer and a conjugate spunbonded nonwoven fabric including conjugate fibers including a low-melting-point component and a high-melting-point component. The conjugate fibers are partially bonded to each other by thermocompression, wherein each bonded portion has fine folded structures including alternate hill and valley regions in the CD, and the distance between neighboring hills is 100-400 ?m in average. The conjugate spunbonded nonwoven fabric exhibits stretchability through the spread of the fine folded structures, and has, at 5% elongation, a CD-strength of 0.1 N/5 cm or less and an MD/CD strength ratio of 200 or more.

  • Patent number: 8399368
    Abstract: A nonwoven web material that contains an elastic component is provided. The elastic component contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic component that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.

    Abstract: An elastomeric laminate that does not require mechanical activation comprises an elastomeric polymer film layer bonded to one or more other substrate layers. The elastomeric film composition, physical properties of the substrate, and bonding conditions are selected and controlled to form an elastomeric laminate that is stretchable and recoverable without the use of excess material or post-lamination mechanical activation. The resulting elastomeric laminate may be manufactured on relatively simple high-speed equipment at lower cost and with improved physical properties.
