Abstract (en)
[origin: WO03066942A1] Non-thermoplastic starch fibers having no melting point and having apparent peak wet tensile stress greater than about 0.2 MegaPascals (MPa). The fibers can be manufactured from a composition comprising a modified starch and a cross-linking agent. The composition can have a shear viscosity from about 1 PascalOESeconds to about 80 PascalOESeconds and an apparent extensional viscosity in the range of from about 150 PascalOESeconds to about 13,000 PascalOESeconds. The composition can comprise from about 50% to about 75% by weight of a modified starch; from about 0.1% to about 10% by weight of an aldehyde cross-linking agent; and from about 25% to about 50% by weight of water. Prior to cross-linking, the modified starch can have a weight average molecular weight greater than about 100,000 g/mol.
