Mechanical properties and solubility of fibre obtained from liquid two‐phase systems water‐casein‐sodium alginate

Abstract

Abstract The mechanical properties (tensile strength and deformation under uniaxial tension and shearing strength) as well as the stability against dissolution of the fibre obtained from the liquid two‐phase system, water‐casein‐sodium alginate, can be much better than the properties of the fibres produced from binary systems, water‐casein and water‐sodium alginate, when concentrations of the macromolecular components and pH of the system are the same. These properties can be controlled by varying the composition of the system and by additional treatment in a 10% solution of CaCl 2 at 100 °C.
