Description

FIBERS COMPRISING CULTIVATED MICROALGAE, METHOD FOR MANUFACTURING THE SAME, AND
YARNS, FABRICS AND GARMENTS COMPRISING SUCH FIBER
TECHNOLOGICAL FIELD
The present invention is directed to fibers, yarns and fabrics comprising at least one cultivated microalgae.
BACKGROUND
The unique properties of algae help to protect our skin against the harmful environmental influences which we are exposed to in our daily lives. The algae are pure and rich in essential substances such as vitamins, trace elements, amino acids and minerals.
The substances found in algae help to activate cell regeneration, which in turn can help to relieve skin diseases, reduce inflammation and soothe itchiness. Its high level of antioxidants protects the skin against harmful free radicals, which damage our skin cells.
The natural moisture level of the skin enables an active exchange of those beneficial substances between the fiber and the skin, providing a noticeable sense of wellbeing.

Solvents used in such processes may be selected from NaOH solution, CS2 solution, acetone, organic solvents, acetic anhydride, amine oxide, cuprammonium liquor, tetraaminecopper dihydroxide, N-methylmorphine N-oxide (NMMO) solution, acetic acid and combinations thereof. In some embodiments, said fiber post-treatment of step (d) is performed by drawing, washing, drying and any combinations thereof.
Example ¨ Preparation of acetate fiber of the invention Acetate fiber is produced by reacting high purity wood pulp and 5% crude cultivated red microalgae with acetic anhydride. The acetate flakes that are produced
8 PCT/IL2018/051236 through this chemical reaction are dissolved in a solvent, filtered, and adjusted to obtain spinning stock solution. The spinning stock solution is extruded through controlled nozzles with extremely small pore diameters ranging from 30 to 50[tm. The solvent is then evaporated, and the yarns are formed. This process for producing acetate fiber is known as the dry spinning method. The cross-section of acetate fiber is called a "chrysanthemum," and is shaped uniquely with many lobes. After the spinning stock has been extruded through the pores, it takes on a round-shaped cross-section.
However, rapid evaporation of the solvent from the surface results in the formation of a skin layer on the surface of the fiber. After that, evaporation of the solvent from the inside of the fiber causes the skin layer to cave in toward the fiber cross-section, giving rise to the final multi-lobal cross-section.
