Amphoteric surfactants as glass fiber dispersants for the manufacture of uniform glass fiber mats

摘要

In accordance with the present invention, there is provided herein improved glass fiber dispersions for making uniform glass fiber mats by the wet-laid process. The well dispersed glass fiber compositions of this invention usually are prepared by mixing chopped glass fiber bundles in water with a small amount of an alkylamidoalkyl sultaine surfactant to disperse the bundles into individual fibers. As a feature of the invention, the dispersions may be formed at relatively high glass fiber consistencies. The resultant dispersions then are used to make very high quality glass fiber mats at high rates of production.
