The anisotropic Cosmological model Bianchi type III for cloud string with volume viscosity are studied, to get the determinate solution, the coefficient of volume viscosity assumed as a power function of an expansion ξ = kθⁿ and shear scalar (σ) is directly proportional to scalar expansion (θ), which leads to the relation between metric potential B = C^α. In the physical features is found that the power ends n has a significant influence on the cloud string model, when n < 1 then ‘big bang’ starts and n > 1 then no big bang start, In the special condition n = 0 the model reduces to the string model of constant-coefficient of volume viscosity.
