US Patent:

7005395, Feb 28, 2006
Filed:

Dec 12, 2002
Appl. No.:

10/317416
Inventors:

Dimitri P. Zafiroglu - Wilmington DE, US
Geoffrey David Hietpas - Newark DE, US
Debora Flanagan Massouda - Wilmington DE, US
Thomas Michael Ford - Greenville DE, US
Assignee:

Invista North America S.a.r.l. - Wilmington DE
International Classification:

D04H 1/006
B32B 5/026
B32B 3/006
US Classification:

442352, 442401, 442360, 442362, 442381, 442382, 428103, 156 85
Abstract:

This invention relates to an improved method for preparing stretchable multiple-component bonded composite sheets which involves bonding a fibrous layer of spirally-crimpable multiple-component continuous filaments or staple fibers to one or more non-spirally-crimpable layers using an array of intermittent mechanical, chemical, or thermal bonds, and heating the bonded composite to activate the spiral crimp of the fibers in the spirally-crimpable layer. Multi-layer nonwoven fabrics prepared according to the method of the current invention have an improved combination of strength, aesthetics, stretch-recovery properties, and textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

US Classification:

28156, 264168, 264155, 442352, 442361, 428369, 428371, 428373
Abstract:

A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

US Patent:

8093161, Jan 10, 2012
Filed:

Sep 27, 2002
Appl. No.:

10/256626
Inventors:

Vishal Bansal - Richmond VA, US
Michael C. Davis - Midlothian VA, US
Thomas Michael Ford - Greenville DE, US

INVISTA North America S.àr.l. - Wilmington DE
International Classification:

D04H 5/00
US Classification:

442334, 442335, 442336, 442337, 442352
Abstract:

The invention relates to nonwoven fabrics containing polymeric multiple component fibers which include a core component and a plurality of wing components attached to the core. The polymeric core component has an elasticity that is greater than the elasticity of at least one of the wing polymeric components. The fibers assume a spiral twist configuration in which the plurality of wings substantially spiral about the core. In a preferred embodiment, the nonwoven fabrics have elastic stretch and recovery properties with a textile-like hand.

Filed:

Sep 2, 1994
Appl. No.:

8/300615
Inventors:

Aysen Dindi - Ponca City OK
Ray L. Johnston - Ponca City OK
Yung N. Lee - Ponca City OK
Debora F. Massouda - Ponca City OK
Assignee:

Conoco In. - DE
International Classification:

C08L 2318
US Classification:

524570
Abstract:

Flow of a stream comprised of hydrocarbons is improved by introducing into the stream a stable, non-agglomerating suspension comprising: (a) water, (b) highly dispersed in the water, and substantially insoluble therein, and extremely finely-divided, non-crystalline, ultra-high molecular weight, hydrocarbon-soluble, undegraded polyalkene having 2 to about 30 carbon atoms per alkene precursor and an inherent viscosity of at least 20 dL/g, and (c) a small but effective amount of a surfactant having a HLB of at least about 9. The finely divided polyalkene is prepared by polymerization and then cryogrinding below the glass transition temperature of the polyalkene.
