| 20110092934 | PRODUCTION OF FINE STUFFERBOX-CRIMPED TOWS FROM SYNTHETIC FILAMENTS AND FURTHER PROCESSING THEREOF INTO TEXTILE HYGIENE ARTICLES - A process is described for producing thin crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped. The process can be carried out in-line with numerous further processing operations. The tows are particularly useful for producing textile hygiene articles such as diapers, sanitary napkins, inserts and incontinence guards and the like. | 04-21-2011 |

| 20110165470 | BICOMPONENT FIBER - The present invention relates to a new bicomponent fiber, a nonwoven fabric comprising said new bicomponent fiber and sanitary articles made therefrom. The bicomponent fiber contains a polyethylene-based resin forming at least part of the surface of the fiber longitudinally continuously and is characterized by a Co-monomer Distribution Constant greater than about 45, a recrystallization temperature between 85° C. and 110° C., a tan delta value at 0.1 rad/sec from about 15 to 50, and a complex viscosity at 0.1 rad/second of 1400 Pa.sec or less. The nonwoven fabric comprising the new bicomponent fiber according to the instant invention are not only excellent in softness, but also high in strength, and can be produced in commercial volumes at lower costs due to higher thoughputs and requiring less energy. | 07-07-2011 |

| 20110195214 | SUPERABSORBENT BI-COMPONENT FIBER - A superabsorbent bi-component fiber, wherein component A is at least one thermoplastic polymer and component B is a compound selected from at least one thermoplastic base polymer and at least one superabsorbent polymer (SAP), and also a method for production thereof are described. The melting point of the thermoplastic contained in component A is at least 20° C. higher than the melting point of the thermoplastic contained in component B, the average grain size of the SAP is 0.5 to 10 μm and the compound has an SAP-fraction of 0.5 to 40 wt %. The bi-component fiber can be used to produce superabsorbent textile fabrics which are used in particular in the field of hygiene and medicine. | 08-11-2011 |
