Abstract
Abstract Fibrous material is provided comprising cellulose fibers and mineral wool fibers in a weight ratio within the range from about 3:7 to about 10:1, impregnated with an amount of a water-soluble polyoxyalkylene ether alcohol sufficient to impart dimensional stability thereto and having the formula: R.sub.1 [--O--(C.sub.n.sbsb.1 H.sub.2n.sbsb.1 --O).sub.x --C.sub.n.sbsb.2 H 2n .sbsb.2 --OH] m wherein: R 1 is hydrocarbon or hydrocarbon substituted with secondary hydroxyl groups and free from primary hydroxyl groups and having from one to about twenty-four carbon atoms; m is a number within the range from 1 to about 6; n 1 is a number within the range from about 2 to about 4; n 2 is a number within the range from 3 to 4; and --C n .sbsb.2 H 2n .sbsb.2 --OH is a branched chain propylene or butylene group having only secondary OH groups; and the total of x in all of the m groups (x multiplied by m) is a number within the range from about 2 to about 200; and optionally also impregnated with a plastic material.
