ABSTRACT:
The disclosed invention relates to a process wherein zein fibers are prepared by mixing zein and water, preferably btween 0.degree. C. and 18.degree. C., to form a free-flowing, particulate mixture; heating the mixture to a temperature of about 45.degree. C. to about 80.degree. C. while simultaneously extruding the mixture through a spinneret to form zein fibers which are subsequently treated with a formaldehyde stabilizing solution and drawn. This process obviates the need for environmentally unfriendly alkaline solutions and acid coagulating baths.
