Patent number: 6024813Abstract: Fibrous structures containing immobilized particulate matter and processes for making them are disclosed. These structures may be used for filters and for fabrics including chemical defense garments and others. The fibrous structures have webs containing composite fibers having a lower melting component and a higher melting component. The particles are distributed into the interior of the web and fused to the low melting component of the individual fibers without substantially reducing the available surface area of the particle. A fibrous structure of a composite staple having a nylon sheath and a polyester core, with activated carbon particles bonded to the sheath is specifically disclosed. The processes for producing such a fibrous structure include carding a web of staple fibers and distributing particulate matter therein, air laying a web of staple fibers and particulate from a suspension thereof between two wet formed layers of staple fibers.Type: GrantFiled: September 3, 1997Date of Patent: February 15, 2000Assignee: AQF Technologies LLCInventors: Herbert Gunter Groeger, George Allibone Serad, Clinton Dale Felton

Patent number: 5779847Abstract: A novel, high performance yet permeable, tough, fibrous structure, and a process for making the structure are disclosed. The fibrous structure includes a stabilized microstructure of improved uniformity of fiber and particulate distribution. Beneficially, the fibrous structure is of improved structural integrity and stiffness, as a result of being reduced in thickness.The process includes the steps of dry forming a fibrous web including crimped staple composite fibers, thereafter distributing and entrapping the functional particles in the web, and thereafter heating the fibrous web to form a microstructure-stabilized fibrous web. According to the process, the microstructure-stabilized fibrous web is thereafter by an additional heat treating step carried out without application of pressure to the web, heated to a thermoforming temperature, and thereafter the heated web is reduced in thickness and yet microstructural relative geometry is maintained. IR heat may be used.Type: GrantFiled: April 22, 1996Date of Patent: July 14, 1998Assignee: Hoechst Celanese CorporationInventor: H. Gunter Groeger
