Description
A fine silklike thread produced by forcing sodium alginate through spinnerets into a solution of a metallic salt, usually beryllium or calcium acetate. This changes the water-soluble alginate into a water-insoluble material. However, because the fibers will still dissolve in aqueous solutions that contain soaps or an alkali, alginic fibers must be dry-cleaned. They are commonly used as a spacing threads to produce fancy weave fabrics. The alginic fibers are woven into a fabric with other types of thread, such as fine wool, then washed out, leaving a loosely woven pattern. Alginic threads are also used to produce silk substitutes, fireproof fabrics, and surgical dressings that can dissolve into the blood stream.
Synonyms and Related Terms
alginic fibre; algin fiber; alginate fiber; fibra algínica (Esp.)
Risks
Nonflammable, but will decompose in flame with ash residue.
Physical and Chemical Properties
Soluble in weak alkalis like soap. Unaffected by organic solvents.
Fibers are striated; cross sections have serrated edges with occasional flat spots. Tenacity = 1.6-2.0 g/denier (dry); 0.5 g/denier (wet );
