| 20090156075 | Multicomponent fiber with polyarylene sulfide component - This invention relates to a multicomponent fiber having an exposed outer surface, comprising at least a first component of polyarylene sulfide polymer, and at least a second component of a thermoplastic polymer free of polyarylene sulfide polymer, wherein said thermoplastic polymer forms the entire exposed surface of the multicomponent fiber. | 06-18-2009 |
| 20100147555 | NON-WOVEN SHEET CONTAINING FIBERS WITH SHEATH/CORE CONSTRUCTION - A non-woven sheet contains sheath/core polymer fibers with the polymer in the sheath having a melting point at least 15 degrees centigrade higher than the melting point of the polymer of the core. Preferably, the polymer of the sheath is polyphenylenesulfide and the polymer of the core is polyethyleneterephthlate. The nonwoven sheet can be used with a film to make a composite laminate suitable for use in electrical insulation. | 06-17-2010 |
| 20100151246 | POLYPHENYLENE SULFIDE SPUNBOND FIBER - The present invention is directed to a spunbond fiber comprising polyphenylene sulfide polymer having a zero shear viscosity at 300° C. of about 21,500 to about 28,000 Pa·s. | 06-17-2010 |
| 20100151760 | NON-WOVEN SHEET CONTAINING FIBERS WITH SHEATH/CORE CONSTRUCTION - A non-woven sheet contains sheath/core polymer fibers with the polymer in the sheath having a melting point at least 15 degrees centigrade higher than the melting point of the polymer of the core. The fibers have an average diameter greater than 7 microns and the sheet has a normalized air resistance greater than 0.25/(g/m | 06-17-2010 |
