Description
Regenerated protein fibers made from corn and maize. Zein fibers were commercially sold as Vicara from 1948 to 1957. They were made with the crushed meal of corn and maize after the oil was extracted. The meal is dissolved in an alkali bath then forced through spinnerets to form fine fibrils that were hardened with Formaldehyde. Fabric made from zein fiber is soft, tough and strong and has the warmth of wool. It is resistant to mildew, insects, sunlight, and temperatures to 140 C. Vicara was usually blended with Cotton, Wool, or rayon. It was used in suits, sweaters, blankets and pile fabrics.
