20090042475 | MIXED FIBERS AND NONWOVEN FABRICS MADE FROM THE SAME - The subject matter disclosed herein relates generally to the production of a predetermined ratio of multicomponent fibers in combination with monocomponent fibers or other multicomponent fibers, preferably through a spunbonding process. After extrusion, these fibers can produce a fiber network that is subsequently bonded to produce a nonwoven fabric comprising multiple types of fibers. The multicomponent fibers within the network may be processed to remove one component by dissolution or to split the individual components into separate fibers. As a result, the fabric will be comprised of fibers with a range of diameters (micro- or nano-denier fibers as well as higher denier fibers) such that the fibers will not pack as tightly as in a homogeneous nonwoven fabric produced from one type of monocomponent or multicomponent fiber. The present invention additionally relates to methods for producing nonwoven fabrics with increased loft, breathability, strength, compressive properties, and filtration efficiency. | 02-12-2009 |

20100041294 | CORE-SHEATH FIBER, NONWOVEN AND ARTIFICAL LEATHER - A core-sheath fiber has a core and a sheath. The core comprises 0.1 to 10 wt % of carbon black pigment particles.

Therefore, a lifetime of a punch needle used in machinery to produce a nonwoven is maintained and the nonwoven can undergo high frequency treatment to form artificial leather. Additionally, the sheath has little or no carbon black pigment particles, so the sheath is improved compatibility with polyurethane (PU) used for high frequency treatment. | 02-18-2010 |
