Abstract

Enhancement of cellulosic paper products with coarse diameter glass wool fibers (average diameter of from about 5.5 µm to about 11 µm) results in stronger, more air resistant, and less hygroexpansive paper products. Paper products comprising cellulose pulp and coarse diameter glass wool fibers are disclosed. Additionally disclosed are methods for making coarse diameter glass wool fiber enhanced cellulosic paper products.

Claims

AMENDED CLAIMS [received by the International Bureau on 04 January 2005 (04.01.2005); original claims 11, 15 amended, remaining claims unchanged (01 page )]
^w 10. The paper product of claim 9, wherein the paper product has an average air resistance of from about 108 to about 97 s/300cm3.
11. The paper product of claim 10, wherein the paper product has an average hygroexpansivity of about 0.08 to about 0.18,
12. The paper product of claim 8, wherein the coarse diameter glass wool fibers comprise about 5% by weight of the total dry weight of the cellulose pulp together with the coarse diameter glass wool fibers.
13. The paper product of claim 12> wherein the paper product has a weight of about
160 grams per square meter, and wherein the paper product has a tearing resistance of about 150 grams of force. 14. The paper product of claim 13, wherein the paper product has an average air resistaπce of about 97 s/300cm3.
15. The paper product of claim 14, wherein the paper product has an average hygroexpansivity of about 0.18,
16. A method of making a paper product comprising; preparing a stock comprising cellulose pulp, coarse diameter glass wool fibers, and an aqueous solution; applying the stock to a screen to form a web; and drying the web to form a paper product.
17. The method of claim 16, wherein the coarse diameter glass wool fibers have an average diameter between about 6.0 and about 10.0 microns. 18. The method of claim 17, wherein the coarse diameter glass wool fibers comprise about 3% to about 5% by weight of the total dry weight of the cellulose pulp together with the coarse diameter glass wool fibers.
