Abstract
Official abstract text for this publication.
The present invention concerns a method for the production of high-filled, preferably wet-laid non-woven fabrics, in particular non-woven glass fiber fabrics, which have a very low binder content, as well as the non-woven glass fiber fabrics produced according to this method and the use thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. A wet-laid or dry-laid non-woven fabric made of inorganic fibers, which is treated with a binder system, binder system I, which has at least one organic binder and at least one inorganic filler, and wherein: (i) the applied quantity of the binder system I is between 30 and 90% by weight, wherein the value refers to the total weight of the non-woven fabric after complete drying, and (ii) the content of organic binder(s) in the binder system I is between 2 and 20% by weight, wherein the value refers to the binder system I after complete drying, (iii) the content of inorganic filler(s) in the binder system I is between 98 and 80% by weight, wherein the value refers to the binder system I after complete drying, (iv) the non-woven fabric consolidated with the binder system I, after drying the binder system I, has a Gurley porosity, base 100 ml, of at most 200 sec; and (v) the non-woven fabric is impregnated with the binder such that the binder system is uniformly distributed within the non-woven fabric. 2. The non-woven fabric according to claim 1 , characterized in that it has the fire class A2. 3. The non-woven fabric according to claim 1 , wherein the applied quantity of the binder system I is between 35 and 75% by weight, wherein the value refers to the total weight of the non-woven fabric after complete drying. 4. The non-woven fabric according to claim 1 , wherein the content of organic binder(s) in the binder system I is between 5 and 16% by weight, wherein the value refers to the binder system I after complete drying. 5. The non-woven fabric according to claim 1 , wherein the content of inorganic filler(s) in the binder system I is between 95 and 84% by weight, wherein the value refers to the binder system I after complete drying. 6. The non-woven fabric according to claim 1 , wherein the non-woven fabric consolidated with the binder system I, after drying of the binder system I, has a Gurley porosity, base 100 ml, of less than 100 sec.
