Abstract
Official abstract text for this publication.
A down-proof woven fabric includes a cloth composed of synthetic fibers with a yarn fineness of 33 decitex or less and having a weight per unit area of 50 g/m 2 or less and a cover factor of 1,400 to 1,800, wherein the cloth is coated at least on one surface thereof with a resin by an amount of 0.1 g/m 2 to 5 g/m 2 as a solid component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A down-proof woven fabric comprising a cloth consisting of synthetic fibers consisting of polymeric resin with a yarn fineness of 33 decitex or less, a weight per unit area of 50 g/m 2 or less and a cover factor of 1,400 to 1,800, wherein the cloth is coated at least on one surface thereof with a resin in an amount of 0.1 g/m 2 to 5 g/m 2 as a solid component to form a non-solid layer and the non-solid layer contains continuous voids, the cloth is calendered at least on one surface thereof, and subsequently coated with the resin on another surface thereof. 2. The down-proof woven fabric according to claim 1 , wherein the resin is a urethane resin. 3. The down-proof woven fabric according to claim 2 , wherein the resin is a non-solvent-based resin. 4. The down-proof woven fabric according to claim 2 , wherein the cloth is subjected to water repellent treatment and subsequently coated with the resin on at least one surface thereof. 5. The down-proof woven fabric according to claim 2 , which has a tear tenacity of 8 N to 30 N. 6. The down-proof woven fabric according to claim 1 , wherein the resin is a non-solvent-based resin. 7. The down-proof woven fabric according to claim 6 , wherein the cloth is subjected to water repellent treatment and subsequently coated with the resin on at least one surface thereof. 8. The down-proof woven fabric according to claim 6 , which has a tear tenacity of 8 N to 30 N. 9. The down-proof woven fabric according to claim 1 , wherein the cloth is subjected to water repellent treatment and subsequently coated with the resin on at least one surface thereof. 10. The down-proof woven fabric according to claim 9 , which has a tear tenacity of 8 N to 30 N. 11. The down-proof woven fabric according to claim 1 , which has a tear tenacity of 8 N to 30 N. 12. The down-proof woven fabric according to claim 1 , which has washing durability capable of holding an air permeability of 0.1 cc/cm 2 /sec to 1.5 cc/cm 2 /sec and a seam slippage of 2.5 mm or less. 13. An article of clothing comprising the down-proof woven fabric set forth in claim 1 . 14. An article of bed clothing comprising the down-proof woven fabric set forth in claim 1 . 15. A down-proof woven fabric comprising a cloth consisting of synthetic fibers consisting of polymeric resin with a yarn fineness of 33 decitex or less, a weight per unit area of 50 g/m 2 or less and a cover factor of 1,400 to 1,800, wherein the cloth is coated at least on one surface thereof with a resin in an amount of 0.1 g/m 2 to 5 g/m 2 as a solid component and then dried to form a non-solid layer and the non-solid layer contains continuous voids, the cloth is calendered at least on one surface thereof, and subsequently coated with the resin on another surface thereof.
