摘要
(WO200056201) A cleaning system is provided comprising a sealable container housing a saturated stack of durable fine spunbond fiber cleaning sheets; the cleaning sheets have an average fiber diameter less than 18 micrometers, a tensile strength of at least 140-g/g/m<2> and a basis weight between about 15 g/m<2> and 85 g/m<2>.  The cleaning sheets can be provided in stacked form and maintained within a sealed container wherein liquid is retained within the individual sheets as well as throughout the stack over time.  The sheets can subsequently be removed from the container and applied to a surface wherein a high percent of the liquid is released from the sheet onto the surface in the initial pass and thereby allowing for improved treatment and/or cleaning of the surface.

主权利要求
(WO200056201) 1. We claim: 1. A liquid delivery system comprising: a sealable container; stacked sheets having at least 10 layers, said sheets comprising spunbond fiber nonwoven webs having a basis weight of at least about 15 g/m2and a tensile strength greater than 0.13-kg per gram per square meter, and wherein said spunbond fibers have an average fiber diameter less than 18 micrometers; and liquid distributed throughout said stacked sheets and wherein said sheets have an initial liquid release of at least about 17%. 2. The liquid delivery system of claim 1 wherein said sheets comprise a pattern bonded nonwoven web of spunbond fibers. 3. The liquid delivery system of claim 1 wherein said sheets comprise a point bonded nonwoven web of spunbond fibers and wherein the bond area comprises between about 5% and about 30% of the surface area of said sheets. 4. The liquid delivery system of claim 1 wherein said liquid is substantially uniformly distributed throughout said stack. 5. The liquid delivery system of claim 4 wherein said sheets have a Taber resistance of at least 50 cycles. 6. The liquid delivery system of claim 4 wherein said sheets contain a wetting agent. 7. The liquid delivery system of claim 5 wherein said spunbond fibers comprise a polyolefin polymer. 8. The liquid delivery system of claim 5 wherein said spunbond fibers comprise a propylene polymer. 9. The liquid delivery system of claim 8 wherein said stack has a height less than 21 cm. 10. The liquid deliver system of claim 9 wherein said sheets have a coarse fiber layer upon the outer surface of at least one side of said sheet. 11. The liquid delivery system of claim 1 wherein said spunbond fiber webs comprise fibers having an average fiber diameter between about 8 and 15 micrometers and a mean pore size between about 15 and about 35 micrometers. 12. The liquid delivery system of claim 3 wherein said sheets have an initial liquid release of at least 20%. 13. The liquid delivery system of claim 12 wherein said spunbond fibers comprise a propylene polymer and wherein said sheets have a basis weight between 15 g/m2and 85 g/m2. 14. The liquid delivery system of claim 13 wherein said spunbond fibers have a Taber resistance of at least 65 cycles and a tensile strength of at least 0.21 -kg per gram per square meter. 15. A liquid delivery system comprising: a sealable container; stacked sheets having a stack height less than 21 -cm and at least 10 layers, said sheets consisting essentially of a bonded spunbond fiber nonwoven web wherein said spunbond fibers have an average fiber diameter less than 18 micrometers and wherein said sheet has a basis weight of at least about 15 g/m2; a liquid distributed throughout said stacked sheets wherein said sheets have a Taber Abrasion Resistance greater than 50 cycles and an initial liquid release of at least about 17%. 16. The liquid delivery system of claim 1 wherein said sheets comprise a pattern bonded web of propylene polymer spunbond fibers having a basis weight between about 15 g/m2and 85 g/m2. 17. The liquid delivery system of claim 16 wherein said sheets have a tensile strength greater than 0.18-kg gram per square meter. 18. The liquid delivery system of claim 17 wherein said sheets contain a wetting agent. 19. The liquid delivery system of claim 17 wherein said sheets have an initial liquid release greater than 20% wherein said liquid is substantially uniformly distributed throughout said stack. 20. The liquid delivery system of claim 19 wherein the spunbond fibers have an average fiber diameter between about 8 and 15 micrometers and a mean pore size between about 15 and about 35 micrometers.
