Abstract
There is disclosed novel glass fiber particularly useful for preparing formed insulating articles having on the surface of the fibers an amorphous aluminum phosphate polymer wherein the polymer resiliently tacks the glass fibers together so as to provide regain of shape after deformation of the fibers as by compression. Also disclosed is a process for preparing glass fiber articles wherein the fibers are contacted with an ionic polymer which is then dehydrated to form an amorphous non-hygroscopic polymer.
Claims6
A process for preparing a form retaining insulating body of glass fibers comprising applying to the fibers a tacking agent comprising an aqueous acid aluminum phosphate solution containing a molar ratio of Al.sub.2 O.sub.3 to P.sub.2 O.sub.5 of less than 1, shaping said body and then removing water from said tacking agent to form an amorphous, water insoluble, non-hygroscopic polymer whereby the glass fibers of the body form are resilently bonded together.
A process for preparing a loose mass of glass fibers which comprises applying to the fibers a tacking agent comprising an aqueous acid aluminum phosphate solution containing a molar ratio of Al.sub.2 O.sub.3 to P.sub.2 O.sub.5 of from 1:2 to 1:4, and then removing water to form an amorphous, water insoluble,non-hygroscopic polymer.
