    Abstract: A composition fiber of cellulose-polyvinyl alcohol and a manufacturing method thereof are provided to prevent the elution of PVA(Polyvinylalcohol) component from generating into a washing cistern. The composition fiber comprises cellulose-polyvinyl alcohol of 70:30-99:1 wt %. In the polyvinyl alcohol, the syndiotactic diad group content is 53 to 63% and the degree of saponification is at least of 99.0%. In the cellulose, alpha-cellulose content is at least 96%. The cellulose-polyvinyl complex fiber has the dry intensity of 6 to 10 g/d, the dry elongation of 6 to 13% and the dry elasticity of 150 to 400 g/d. In the polyvinyl alcohol, viscosity-average degree of polymerization is 1500 to 1700. The mixing powder of the cellulose or syndiotactic polyvinyl alcohol is dissolved in the N-methylmorpholine-N-oxide solvent so that the dope is manufactured. The dope is spun by a spin nozzle. The spun filament is washed. At the washing process, the elution rate of polyvinyl alcohol is below 5%.
