Claims
- 1. An analysis material sheet, comprising:
- a water-impermeable support; and
- a fabric layer comprising a fabric including about 10% or more of a polyethyleneterephthalate synthetic hydrophobic organic polymer fiber and the remainder being natural fiber provided on said support, said fabric layer containing a reagent and being physically activated on at least one surface thereof to render the fabric layer hydrophilic and provide increased adhesiveness, with said physically activated surface being adhered to said support to form an integral structure, wherein said physical activation is conducted by a treatment selected from the group consisting of a glow discharge treatment, plasma discharge and a corona discharge treatment.
- 2. An analysis material sheet as claimed in claim 1, wherein an adhesive layer is provided between said support and said fabric layer.
- 3. An analysis material sheet as claimed in claim 1, wherein said fabric layer comprises about 30% or more of said hydrophobic organic polymer fiber.
- 4. An analysis material sheet as claimed in claim 1, wherein said natural fiber is fiber selected from the group consisting of cotton, kopak, flax, hemp, ramie and silk.
- 5. An analysis material sheet as claimed in claim 1, wherein the fabric layer comprises 100% of said hydrophobic organic polymer fiber.
- 6. An analysis material sheet as claimed in claim 1, wherein said fabric layer comprises mixed yarns.
- 7. An analysis material sheet, comprising:
- a reagent layer containing a reagent and having provided thereon a liquid sample-spreading layer of fabric, said fabric layer comprising a fabric including about 10% or more of a polyethyleneterephthalate synthetic hydrophobic organic polymer fiber and the remainder being natural fiber, and being physically activated on at least one surface thereof to render the fabric layer hydrophilic and provide increased adhesiveness, with said physically activated surface being adhered to said reagent layer to form an integral structure, wherein said physical activation is conducted by a treatment selected from the group consisting of a glow discharge treatment, plasma discharge treatment and a corona discharge treatment.
- 8. An analysis material sheet as claimed in claim 7, wherein an adhesive layer is provided between said reagent layer and said fabric layer.
- 9. An analysis material sheet as claimed in claim 7, wherein said fabric layer comprises about 30% or more of said hydrophobic organic polymer fiber.
- 10. An analysis material sheet as claimed in claim 7, wherein said natural fiber is fiber selected from the group consisting of cotton, kopak, flax, hemp, ramie and silk.
- 11. An analysis material sheet as claimed in claim 7, wherein the fabric layer comprises 100% of said hydrophobic organic polymer fiber.
- 12. An analysis material sheet as claimed in claim 7, wherein said fabric layer comprises mixed yarns.
- 13. An analysis material sheet as claimed in claim 1, wherein said fabric layer is provided directly on said water-impermeable support.
- 14. An analysis material sheet as claimed in any of claims 1 or 13, wherein said fabric layer is physically activated on both surfaces.
- 15. An analysis material sheet as claimed in claim 7, wherein said reagent layer is provided directly on said layer of fabric.
- 16. An analysis material sheet as claimed in any of claims 7 or 15, wherein said layer of fabric is physically activated on both surfaces.
- 17. An analysis material sheet as claimed in any of claims 1 or 15, wherein said reagent layer is water-permeable and has a transparent, water-impermeable support provided on a side opposite said spreading layer.
- 18. An analysis material sheet as claimed in any of claims 1 or 7, wherein the physical activation is a plasma discharge treatment.
- 19. An analysis material sheet as claimed in any of claims 1 or 5, wherein the physical activation is a corona discharge treatment.
- 20. An analysis material sheet as claimed in any of claims 1 or 7, wherein the physical activation is a glow discharge treatment.
- 21. An analysis material as claimed in claim 20, wherein the synthetic hydrophobic organic polymer fiber comprises 30% or more of the fabric layer.
- 22. An analysis material sheet as claimed in claim 21, wherein the synthetic hydrophobic organic polymer fiber comprises 100% of the fabric layer.
