US Patent:

6682672, Jan 27, 2004
Filed:

Jun 28, 2002
Appl. No.:

10/184048
Inventors:

Kunihiko Takeuchi - Conyers GA
Assignee:

Hercules Incorporated - Wilmington DE
International Classification:

D01D 402
US Classification:

264 83, 264168, 26417215, 2641761, 26417713, 26421114
Abstract:

Spinnerette including a plate including a plurality of capillaries which have capillary ends with dividers which divide each capillary end into a plurality of openings, and a process of making polymeric fiber. The process includes passing a molten polymer through a spinnerette comprising a plurality of capillaries which have capillary ends with dividers which divide each capillary end into a plurality of openings so that the molten polymer is formed into separate polymeric fibers for each opening or the molten polymer is formed into partially split fiber for each capillary, and quenching the molten polymer to form polymeric fiber.

US Patent:

57051194, Jan 6, 1998
Filed:

Feb 7, 1996
Appl. No.:

8/598168
Inventors:

Kunihiko Takeuchi - Conyers GA
Rakesh K. Gupta - Conyers GA
Shiv Sibal - Conyers GA

Walter J. Freeman - Landenberg PA
Assignee:

Hercules Incorporated - Wilmington DE
International Classification:

D01F 110
D01F 604
D01F 806
D01F 1104
US Classification:

264464
Abstract:

Process and apparatus for spinning polymer filaments permits the obtaining of skin-core filament structure by feeding a polymer composition to a spinnerette at a flow rate sufficient to obtain a spinning speed of about 10 to 200 meters per minute through the spinnerette; heating the polymer composition at a location at or adjacent to the spinnerette so as to heat the polymer composition to a sufficient temperature to obtain a skin-core filament structure upon quenching in an oxidative atmosphere; extruding the heated polymer composition through the spinnerette at a spinning speed of about 10 to 200 meters per minute to form molten filaments; and quenching the molten filaments in an oxidative atmosphere so as to effect oxidative chain scission degradation of at least a surface of the molten filaments to obtain filaments having a skin-core structure.

6/791000
Inventors:

Charles H. Miller - Newark OH
Kunihiko Takeuchi - Newark OH
Paul A. Goodridge - Granville OH
Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:

C03B 3704
US Classification:

65 14
Abstract:
