METHOD OF ENCREASING THE STRENGTH OF WET GLASS FIBER MATS MADE BY THE WET-LAID PROCESS

摘要

Abstract of the DisclosureIn accordance with the present invention, there isprovided herein a method of increasing the strength of wetglass fiber mats prepared by the wet-laid process. Thewet-strength of such freshly prepared glass fiber mats areimproved in this invention by treating the wet mat with adilute solution of an anionic surfactant. As a feature ofthe invention, the wet-strength of such mats are increasedsubstantially so that they may be conveniently handled andtransferred, even manually, for further processing, e.g.for applying binders and drying, into the finished glassfiber mat product.
