Process of making wool-like cellulosic textile materials

Claim 1

A METHOD FOR PREPARING A CELLULOSE TEXTILE MATERIAL POSSESSING SUBSTANTIALLY THE SINGLE FIBER, LIVELINESS, CREASE RESISTANCE AND BULK CHARACTERISTICS OF WOOL, COMPRISING REACTING A CELLULOSE TEXTILE MATERIAL UNDER ANHYDROUS CONDITIONS IN THE PRESENCE OF A NITROGENEOUS CHEMICAL SWELLING AGENT FOR CELLULOSE SELECTED FROM THE GROUP CONSISTING OF AMMONIA AND AMINE COMPOUNDS WHICH SWELL THE CELLULOSE AND FORM NITROGENEOUS COMPLEXES WITH THE CELLULOSE AND CONTAINING A RADICAL SELECTED FROM THE GROUP CCONSISTING OF -NH2 AND >NH, WITH A WATER HYDROLYZABLE ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF (1) AN ESTER CORRESPONDING TO THE FORMULA ME(OR), WHEREIN ME IS A METAL SELECTED FROM THE GROUP CONSISTING OF TITANIUM, ZIRCONIUM, HAFNIUM, THORIUM, ALUMINUM AND IRON AND WHICH FORMS A WATER-INSOLUBLE OXIDE AND HAS A VALENCE SELECTED FROM THE GROUP CONSISTING OF 3 AND 4 AND A COORDINATION NUMBER IN THE OXIDE STATE AT LEAST ONE GREATER THAN THE VALENCE, R IS SELECTED FROM THE GROUP CONSISTING OF HYDROCARBON AND CHLORINATED HYDROCARBON RADICALS, AND X CORRESPONDS TO THE VALENCE OF THE METAL, AND (2) A CONDENSED ESTER OF SAID HYDROLYZABLE ESTER RESULTING FROM THE REACTION OF SAID ESTER WITH WATER, CONTINUING SAID REACTION UNTIL A HIGHLY TENDERED METAL ESTERAMINE CELLULOSE COMPLEX INTERMEDIATE PRODUCT IS FORMED OF SUBSTANTIALLY REDUCED TENSILE AND TEAR STRENGTH OVER THAT OF THE SWOLLEN CELLULOSE TEXTILE, OBTAINED FROM SAID CHEMICAL SWELLING AGENT TREATMENT CONTACTING SAID METAL ESTER-AMINE CELLULOSE COMPLEX INTERMEDIATE PRODUCT WITH AQUEOUS MEDIA CONSISTING ESSENTIALLY OF WATER WHICH REGENERATES AND RESTORES SAID PRODUCT TO SUBSTANTIALLY THE TENSILE STRENGTH OF THE ORIGINAL UNTREATED CELLULOSE TEXTILE MATERIAL, AND RECOVERING THE RESULTING CHEMICALLY MODIFIED CELLULOSE PRODUCT.
