Porous, fibrous materials such as non-woven polyester or polypropylene web materials, cotton web, paper and other materials are saturated with a storage stable one-package latex composition. The latex composition is modified with a temperature sensitive cross-linking agent and neutralizing agents. The latex composition is tailored such that a fibrous material may be impregnated and dried at controlled temperature whereby a thermoplastic resin saturant web intermediate stock material having the thermoset properties is produced. The cross-linking system in the latex composition is later activated in a specific manufacturing process at heat forming and molding temperatures to obtain a specifically shaped manufacture of desired rigidity and flexibility. |
