Water resistant fibrous material

摘要

A method of providing a water resistant treatment on a fibrous cellulosic material, the method including the steps of coating the cellulosic material with a waterproofing globular protein such as ovalbumen in water, heating the coated material to about 180 DEG C to bring the protein into stable chemical contact with the cellulose and allowing to cool. The process is applicable to paper and cotton materials and it allows good waterproofing from a water-based treatment.
