A volatile dispenser is provided, including a reservoir containing a quantity of volatile liquid having a viscosity of no greater than 3.9 centipoises. Each of its individual components has a vapor pressure of no less than 0.008 mm Hg. The dispenser also includes an emanator fluidly coupled to the reservoir (either directly or through a wick) that is comprised of elongated oriented bonded fibers, the fibers being impermeable to the volatile material.

I claim: 1. A volatile liquid dispenser comprises: an impermeable reservoir containing a volatile liquid to be dispensed; a wick in fluid communication with the liquid; and an emanator in fluid communication with the wick, wherein the emanator has a horizontal length extending between opposite ends
I claim: 1. A volatile liquid dispenser comprises: an impermeable reservoir containing a volatile liquid to be dispensed; a wick in fluid communication with the liquid; and an emanator in fluid communication with the wick, wherein the emanator has a horizontal length extending between opposite ends, and wherein the volatile liquid has a viscosity of no more than about 3.9 centipoises and further wherein the emanator is comprised of non-porous fibers that are thermally bonded together and oriented in parallel with and extend the length of the emanator. 2. The dispenser of claim 1, wherein the fibers include polyester fibers with a coating of high density polyethylene. 3. The dispenser of claim 2, wherein the fibers are bonded together by thermal fusion. 4. The dispenser of claim 3, wherein the volatile liquid has a viscosity of no more than about 2.5 centipoises. 5. The dispenser of claim 4, wherein an active ingredient of the volatile liquid is a scent, an insecticide, an attractant, a repellant, a sanitizer, a cleanser, an aromatherapeutic agent, or a medicinal fluid. 6. The dispenser of claim 4, wherein at least 95% by weight of all components comprising the volatile liquid have vapor pressures of no less than about 0.008 mm Hg at 20 degrees centigrade. 7. The dispenser of claim 1, wherein all components of the volatile liquid have a vapor pressure of no less than about 0.008 mm Hg at 20 degrees centigrade. 8. A volatile liquid dispenser, comprising: an impermeable reservoir containing a volatile liquid to be dispensed, wherein the volatile liquid has a viscosity of no more than about 2.5 centipoises; a wick in fluid communication with the liquid; and an emanator in fluid communication with the wick, wherein the emanator is comprised of bonded, oriented, non-porous polyester fibers with a coating of high density polyethylene; wherein the fibers are bonded together by thermal fusion; wherein at least 95% by weight of all components comprising the volatile liquid have vapor pressures of no less than about 0.008 mm Hg at 20 degrees centigrade; and wherein the emanator has a thickness in a first direction orthogonal to a longitudinal extent of the fibers, wherein the thickness being no more than 3.5 mm, and a width in a second direction orthogonal to both the first direction and the longitudinal extent, wherein the width is no less than 10 mm. 9. The dispenser of claim 1, wherein the fibers are selected from the group consisting of polyester, polypropylene, nylon, low density polyethylene, and high density polyethylene. 10. The volatile liquid dispenser of claim 1, wherein the emanator further comprises capillary channels throughout the body of the emanator. 11. The volatile liquid dispenser of claim 10, wherein the capillary channels are not sealed over entire lengths thereof. 12. The volatile liquid dispenser of claim 11, wherein the capillary channels have random interconnecting points disposed along lengths thereof. 13. The volatile liquid dispenser of claim 1, wherein the volatile liquid carried in the emanator is conveyed longitudinally and laterally. 14. The volatile liquid dispenser of claim 1, wherein the fibers have a diameter of between 0.010 and 0.075 mm. 15. The volatile liquid dispenser of claim 14, wherein the fibers have a diameter of between 0.018 and 0.025 mm. 16. The volatile liquid dispenser of claim 1, wherein the emanator has a thickness of between 1 mm and 3.5 mm, a width of between 10 mm and 50 mm, and a length of between 30 mm and 70 mm. 17. The volatile liquid dispenser of claim 16, wherein the length of the emanator is horizontally arranged. 18. The volatile liquid dispenser of claim 1, wherein the fibers extend horizontally. 19. The volatile liquid dispenser of claim 1, wherein the fibers are oriented substantially perpendicularly to the wick. 20. A volatile liquid dispenser, comprising: a reservoir containing a volatile liquid; a wick in fluid communication with the volatile liquid; and an emanator having a length extending between opposite ends and comprised of non-porous fibers that are thermally bonded together and oriented in parallel with and extend the length of the emanator, wherein the volatile liquid has a linear release rate of vaporization from the emanator.
