| 20120034837 | BREATHABLE LAMINATE AND METHOD OF MAKING SAME - A breathable laminate has a liquid-resistant backing film layer having varied vapor permeability that includes breathable thinned localized regions and thicker non-breathable regions, wherein the film layer is co-extensively directly joined with a liquid- and vapor-permeable nonwoven fabric. The breathable laminate can have unidirectional air permeability. The present invention also relates to disposable apparel and absorbent products which incorporate the breathable laminate, and methods of making the breathable laminate. | 02-09-2012 |
| 20110159063 | Method of Cleaning Using An Anti-Microbial Nonwoven Wipe - The present invention is directed to a method of cleaning a hard surface with a nonwoven anti-microbial hard surface wipe, and more specifically to an anti-microbial hard surface wipe that more readily releases a disinfectant or anti-microbial agent, that includes coating a nonwoven wipe having a fibrous nonwoven substrate with a non-ionic and cationic binder mixture to provide a first coated nonwoven wipe, coating the first coated nonwoven wipe with a cationic dual quaternary ammonia anti-microbial agent to provide a second coated nonwoven wipe, providing a water source, and introducing the second coated nonwoven wipe to the water source wherein the cationic dual quaternary ammonia anti-microbial agent is readily released upon the second coated nonwoven wipe being introduced to the water source. | 06-30-2011 |
| 20110147301 | NONWOVENS AND ARTICLES CONTAINING SUBMICRON FIBERS - Nonwoven web products containing sub-micron fibers, and more specifically nonwoven web products having sub-micron fibers formed by fibrillation of polymer films, and nonwoven materials and articles incorporating them, and methods of producing these products. | 06-23-2011 |
| 20100120314 | APPARATUS FOR PRODUCING SUB-MICRON FIBERS, AND NONWOVENS AND ARTICLES CONTAINING SAME - An apparatus for producing sub-micron fibers, and more specifically an apparatus for effecting formation of sub-micron fibers by fibrillation of polymer films, and nonwoven materials and articles incorporating them. | 05-13-2010 |
| 20100098919 | FLAME-RETARDANT CELLULOSIC NONWOVEN FABRIC - The present invention is directed to a hydroentangled flame retardant nonwoven fabric, and more specifically, to a cellulosic flame retardant fabric comprising a self extinguishing fiber so as to minimize the total percentage of fabric weight lost upon burning in accordance with technical bulletin 604. Use of natural fiber fabrics in bedding components is desirable due to the softness and durability associated with the fabrics; however, natural fiber, such as cellulose, is highly flammable and therefore lacks the ability to provide the proper flammability protection often sought out in bedding components. In accordance with the present invention, a small amount of self-extinguishing fiber, such as a modacrylic fiber, was blended with the natural fiber and hydroentangled to form a nonwoven composite fabric that is soft, flame retardant, and suitable for bedding articles. | 04-22-2010 |
| 20100081354 | Nonwoven Multilayered Fibrous Batts And Multi-Density Molded Articles Made With Same And Processes Of Making Thereof - Thermal compression moldable nonwoven multilayered fibrous batts having substantially uniform density are provided, which are useful, for example, for fabrication of multi-density molded parts, such as multi-density molded vehicle liners. The nonwoven multilayered fibrous batts of uniform density comprising needle-punched first and second (and optionally third and/or fourth) fibrous batt layers formed with different fiber blends, wherein the multilayered batt can be molded into acoustical parts having multi-densities. | 04-01-2010 |
| 20090305590 | Durable Flame-Retardant Nonwoven Fabric - This invention relates to a durable fire retardant nonwoven fabric and method of making the same. Said fabric performs in accordance to the requirements set forth in Technical Bulletin 603 of the State of California Department of Consumer Affairs (TB_603), wherein the fire retardant fabric includes at least two layers including at least one strength and reinforcing layer. | 12-10-2009 |
| 20090295020 | Apparatus and Die Cartridge Assembly Adapted for Use Therewith, and Process for Producing Fibrous Materials - Apparatus ( | 12-03-2009 |
| 20090246492 | Multi-Lobal Fiber Containing Nonwoven Materials and Articles Made Therefrom - Nonwoven polymer materials and articles made therefrom. Materials of the invention include at least one nonwoven polymer web with at least one layer of at least about 50% by weight of a multi-lobal fiber. Materials and articles of the invention have improved properties, such as particle retention capacity, acoustic absorption, stiffness, crop color uniformity, and crop yield, when compared with nonwoven polymer materials and articles made with round fiber in place of all of the multi-lobal fiber. | 10-01-2009 |
| 20090169885 | Composite Reinforcement Fiber Having Improved Flexural Properties, And Castable Products Including Same, And Methods - Improved fibrous structural reinforcements ( | 07-02-2009 |
| 20090039564 | PROCESS AND APPARATUS FOR FORMING UNIFORM NANOFIBER SUBSTRATES - The present invention is directed to a method and apparatus for making nanofiber webs, wherein a source of process air is utilized to affect the spray pattern and quality of fibrillated material expressed from a die assembly including a multi-fluid opening. Appropriately, the aforementioned process air is defined herein as an alternate or ancillary air source apart from primary process air, which primary air is simultaneously supplied with the molten polymeric material to the fiber forming multi-fluid opening. The ancillary air source of the invention is further distinct from secondary air, which is also known in the art as quenching air. The ancillary air can be described as a continuous fluid curtain of shielding or shaping air. | 02-12-2009 |
