Method of spinning protein-detergent filament

Claim 1

A METHOD FOR THE PRODUCTION OF A FIBROUS PROTEIN MATERIAL WHICH COMPRISES THE STEPS OF FORMING A MIXTURE COMPRISING A PROTEIN, AN ORGANIC SULFONATE DETERGENT, A STRONG ALKALI AND WATER, SAID PROTEIN BEING PRESENT IN AMOUNT BETWEEN 12 AND 16% BASED ON THE WEIGHT OF SAID MIXTURE, SAID DETERGENT BEING PRESENT IN AMOUNT BETWEEN 2.5 AND 4.8%, BASED ON THE WEIGHT OF SAID MIXTURE, SAID PROTEIN AND SAID DETERGENT BEING PRESENT IN RELATIVE PROPORTIONS BETWEEN 77 PARTS BY WEIGHT OF PROTEIN TO 23 PARTS OF DETERGENT AND 83 PARTS BY WEIGHT OF PROTEIN TO 17 PARTS OF DETERGENT, AND SAID ALKALI BEING PRESENT IN AMOUNT SUFFICIENT TO IMPART TO SAID MIXTURE A PH BETWEEN 11.8 AND 11.9, PASSING SAID MIXTURE THROUGH A CONSTRICTED ZONE TO FORM A FILAMENT THEREOF, IMMERSING SAID FILAMENT IN AN ACID-SALT BATH TO COAGULATE SAID PROTEIN, THEREBY CONVERTING THE SAME TO A FIBER, AND STRETCHING, CURING, WASHING AND DRYING SAID FIBER.

Claim 2

A METHOD FOR THE PRODUCTION OF A FIBROUS PROTEIN MATERIAL WHICH COMPRISES THE STEPS OF FORMING A MIXTURE COMPRISING A PROTEIN, AN ORGANIC SULFONATE DETERGENT, A STRONG ALKALI AND WATER, SAID PROTEIN BEING PRESENT IN AMOUNT BETWEEN 12 AND 16% BASED ON THE WEIGHT OF SAID MIXTURE, SAID DETERGENT BEING PRESENT IN AMOUNT BETWEEN 2.5 AND 4.8%, BASED ON THE WEIGHT OF SAID MIXTURE, SAID PROTEIN AND SAID DETERGENT BEING PRESENT IN RELATIVE PROPORTIONS BETWEEN 77 PARTS BY WEIGHT OF PROTEIN TO 23 PARTS OF DETERGENT AND 83 PARTS BY WEIGHT OF PROTEIN TO 17 PARTS OF DETERGENT, AND SAID ALKALI BEING PRESENT IN AMOUNT SUFFICIENT TO IMPART TO SAID MIXTURE A PH BETWEEN 11.8 AND 11.9, PASSING SAID MIXTURE THROUGH A CONSTRICTED ZONE TO FORM A FILAMENT THEREOF, IMMERSING SAID FILAMENT IN AN ACID-SALT BATH TO COAGULATE SAID PROTEIN, THEREBY CONVERTING THE SAME TO A FIBER, AND STRETCHING, CURING, WASHING AND DRYING SAID FIBER.
