: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows; 1. A method for pulping straw comprising: mixing straw chips with steam and water to form a mixture; exposing the mixture to temperatures and pressures sufficient to significantly soften the straw chips to form straw pulp, lignins and hemicellulose when exposed to a rapid decrease in pressure; passing the mixture through a press to separate a portion of Iignins and hemicellulose from the straw pulp; passing the straw pulp through a defiberizer to form fierier straw pulp; and treating the fierier straw pulp with a caustic solution to provide caustic treated straw pulp. 2. The method of Claim ! wherein the straw chips are mixed with a caustic before the mixture of straw chips, steam and water is exposed to temperatures and pressures sufficient to significantly soften the straw chips to form straw pulp, lignin’s and hemicellulose in the mixture when exposed to a rapid decrease in pressure.
