Abstract
Method for making alloy fibers having high fluid-holding capacity, the alloy fibers being comprised of a matrix of regenerated cellulose having alkali metal salts of alginic acid uniformly dispersed therein.
Claims12
An article of manufacture comprising a highly fluid absorbent mass of alkaline alloy fibers comprising a matrix of regenerated cellulose and an alginic acid salt of alkali-metals dispersed therein, said salt being present in an amount of at least about 5 weight percent based on the weight of the cellulose.
An alkaline alloy fiber comprising a matrix of regenerated cellulose and alginic acid salt of alkali-metals, said fiber having a lubricating finish for cellulose thereon said salt being such, and present in such proportion, within the range of about 5 to about 30 percent based on the weight of cellulose, that the "fluid-holding capacity" is at least 4.79 cc./g.
A method of preparing highly absorbent alloy fibers comprising mixing an alginic acid salt of alkali-metals with a filament-forming viscose whereby the viscose predominates in the mixture, forming the mixture into fibers, coagulating and regenerating the fibers, applying a lubricating finish for cellulose to said fibers, and drying the fibers in an alkaline state with said alginic acid salt in said fiber in the form of an alkali-metal salt, the proportion of said alginic acid salt added to said viscose being at least about 5% based on cellulose.
