Abstract: The present invention is a lightweight carpet for use in aircrafts that meets rigorous fire standards testing, is impervious to fluids, and is capable of being printed for decorative effect. In one embodiment, the carpet composed of a layer of fire retardant treated PET fibers adhered to a fire retardant treated PE film. This carpet is durable to normal foot traffic, resistant to most stains, non-fraying, and can be recycled.

Abstract: Antimicrobial/antifungal fluid conduits (are extruded, co-extruded, molded and/or otherwise thermoformed or thermoset), and films formed on non-thermoplastic conduit walls. One or more inorganic antimicrobial agents are selectively dispersed and concentrated near a surface at which antimicrobial/antifungal properties are desired. The agents resist wear from repeated fluid flows through embedding in a thin thermoplastic layer disposed upon the conduit wall. The fluid conduits preferably comprise high tenacity polymers (e.g. PET, PE, PP, ABS, PVC, Styrene, EVA) in at least one structurally supportive layer and the same or other thermoplastic or thermoset polymer in the thin inner layer including the antimicrobial agents.

Abstract: Anti-microbial and/or anti-fungal synthetic hollow fiber (2) and various products made partially or wholly therefrom are formed in pure hollow or mock-hollow shapes and composed of various thermoplastic polymers having dispersed therein organic or inorganic, antimicrobial additives. The thickness of the fiber walls are optimally equal to or slightly less than the average maximum dimensions of the anti-microbial additive particles. Thus, a portion of the additive particles will be present at outer and/or inner surfaces of the fiber walls, effectively imparting antimicrobial characteristics to the hollow fiber and any fibrous products made therefrom. The additives can be selectively dispersed in certain regions of the fibers in order to reduce the amount of the additives required, and are resistant to separation from the fiber wall, prolonging the fiber's antimicrobial effectiveness.

Abstract: An anti-microbial and/or anti-fungal synthetic fiber that comprises various thermoplastic polymers and additives in a bi-component form in either a core-sheath or side-by-side configurations. The anti-microbial synthetic fibers comprise inorganic anti-microbial additives, distributed in certain areas to reduce the amount of the anti-microbial agents being used, and therefore the cost of such fibers. The fibers can incorporate anti-microbial additives so that they are not removed by repeated washing in boiling water and in dry clean cycles and become ineffective and conversely enhance access to the additives by washing or the like. The fibers comprise high tenacity polymers (e.g. PET) in one portion and hydrolysis resistance polymers (e.g. PCT) in another portion with the additives. The fibers can further be blended with non-anti-microbial fibers such as cotton, wool, polyester, acrylic, nylon etc. to provide anti-microbial finished fabrics.

Abstract: Synthetic plastic fibers are enhanced by inclusions therein of micro-polyester particles (4), preferably sized or otherwise optimized to enhance surface (10) characteristics (abrasion resistance, hydrophilicity, coating receptiveness, increase dullness), reduce UV degradation. The synthetic plastic matrix is preferably polyester but can be any synthetic plastic. The invention is preferentially implemented in multi-component fibers (e.g. core (6)-sheath (8) bi-component fibers (3)) with the inclusions entirely or primarily in one or some, but not all such components. The PTFE inclusions, sizing, concentration, morphology can be adjusted to optimize their enhancing effects, reduce costs and enhance throughput of fiber production. Co-inclusions can be made with the PTFE including anti-microbial and/or coloring agents and with synergistic effects.

Abstract: An anti-microbial and/or anti-fungal synthetic fiber and various products made partially or wholly therefrom. Anti-microbial fabrics, garments and articles made from fibers that may comprise various thermoplastic polymers and additives in a mono-component form or a bi-component form in either a core-sheath or side-by-side configurations. The anti-microbial synthetic fibers comprise inorganic anti-microbial additives, distributed in certain areas to reduce the amount of the anti-microbial agents being used, and therefore the cost of such fibers. The fibers can incorporate anti-microbial additives so that they are not removed by repeated washing in boiling water and in dry clean cycles and become ineffective and conversely enhance access to the additives by washing or the like. The fibers comprise high tenacity polymers (e.g. PET) in one portion and hydrolysis resistance polymers (e.g. PCT) in another portion with the additives.

Abstract: Bi-component spiral crimped flame retardant fibers, and methods of manufacture thereof, are provided with side-by-side (10, 12) and core-sheath (14) arrangements of extruded PET materials having differing intrinsic viscosities. This difference leads to differential shrinkage and crimping through heating during manufacture of the fiber arrangement. Only one of the components exhibits flame-retardant qualities, the qualities imparted by flame-retardant additives (20) or polymers. Other embodiments include anti-microbial additives (22) interspersed in at least one of the extrusions.
